we should invest $479.17 each month to accumulate $81,000 in 12 years with an APR of 4 percent.
what is percent?
Percent is a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin phrase "per centum," which means "by the hundred."
In the given question,
To calculate the monthly deposit needed to accumulate $81,000 in 12 years with an APR of 4%, we can use the formula for future value of an annuity:
FV = PMT x [(1 + r)ⁿ - 1] / r
Where:
FV = Future value of the investment (in this case, $81,000)
PMT = Monthly deposit
r = APR / 12 (monthly interest rate)
n = Number of months (12 years x 12 months per year = 144 months)
Substituting the given values, we get:
$81,000 = PMT x [(1 + 0.04/12)¹⁴⁴ - 1] / (0.04/12)
Simplifying this equation, we get:
PMT = $81,000 x (0.04/12) / [(1 + 0.04/12)¹⁴⁴ - 1]
PMT = $479.17
Therefore, you should invest $479.17 each month to accumulate $81,000 in 12 years with an APR of 4%.

With the given values of circle, the value of x=3 and VS = 5.
What is circle?
A circle is a geometrical shape consisting of all the points in a plane that are equidistant from a given point called the center of the circle.
Since VZ = UZ, then Z is on the perpendicular bisector of QR and ST. This means that Z divides QR and ST into two equal parts.
Using the midpoint formula, we can find the midpoint of QR and ST:
Midpoint of QR = ( (1/2)*(4x-2) , 0 ) = (2x-1, 0)
Midpoint of ST = ( (1/2)*10 , 8 ) = (5, 8)
Since Z is the midpoint of QR and ST, we can set up two equations:
2x-1 = 5
0 = 8
The second equation is not possible, so we ignore it. Solving the first equation gives us:
2x-1 = 5
2x = 6
x = 3
Now that we know x, we can find the length of VS:
VS = ST - TV = ST- (ST/2) = 10 - (5) = 5
Therefore, x = 3 and VS = 5.

What is the area of a right triangle with a height of seven and three fourths yards and a base of 20 yards?
140 yds2
155 yds2
thirty eight and three fourths yds2
seventy seven and one half y
Answer: If the height of seven and three fourths yards and a base of 20 yards, then the area of the right triangle is 77.5 square yards.
To calculate the area of a right triangle, we can use the formula:
Area = (base * height) / 2
where the base is one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.
In this case, the height of the right triangle is 7 and 3/4 yards, and the base is 20 yards. Plugging these values into the formula, we get:
Area = (20 * 7.75) / 2 = 155 / 2 = 77.5 square yards
In summary, to calculate the area of a right triangle, we can use the formula that relates the base and height to the area. In this case, we needed to use the given values of the height and base of the right triangle to compute the area in square yards.
The resulting area represents the amount of surface inside the triangle and is useful in many applications, such as geometry, physics, and engineering.

What is right angle similar triangle?If the hypotenuse and one of the legs of one right triangle are proportional to their relative lengths in the second right triangle, then the two triangles are comparable.
Right triangles don't all look the same. There are two right triangles that we can have where this is not the case. For two triangles to be comparable, the ratios comparing the lengths of their respective sides must all be equal.
Use the Pythagorean theorem to solve the tiny right triangle in ΔBCE;
BC² = BE² + EC²
x² = 8² + 6²
x² = 64 + 36
x² = 100
Then, x = 10
Apply the Pythagorean theorem once more to the triangle with upper right angle ΔABE;
AB² = BE² + AE²
AB² = 8² + y²
AB² = 64 + y²
Apply the Pythagorean theorem to the large right triangle ΔABC as well.
AC² = AB² + BC²
(6 + y)² = AB² + x² (put all above values)

5 hours at 12 mph and 6 hours at 10 mph.
Define about the relation of speed and time:In the study of physics, the three key variables are speed, distance, and time. How quickly or slowly an object moves through one point to another is determined by the concept of speed. The distance travelled in a unit of time is referred to as speed. Distance is exactly proportional to velocity and speed, while time is constant.
The formula for speed:
speed = distance/time
Then ,
time = distance / speed
Let speed S1 = 12 mph , for this time taken t1.
Let the speed S2 = 10 mph , for this time taken t2.
Since, in each distance is same say 'd'.
Total time t = 11 hours.
t = t1 + t2
t = d/s1 + d/s2
11 = d(1/12 + 1/10)
11 = d(12+10) / (12*10)
d = 11*120 / 22

What do you mean by the term Triangle and kinds of triangle ?A triangle is a geometrical figure with three straight sides and three angles. It is the simplest polygon and the building block for more complex shapes.
There are several kinds of triangles:
Equilateral triangle: This is a triangle with three equal sides and three equal angles of 60 degrees each.
Isosceles triangle: This is a triangle with two equal sides and two equal angles.
Scalene triangle: This is a triangle with no equal sides or angles.
Right-angled triangle: This is a triangle with one angle of 90 degrees, which is also known as the right angle. The side opposite to the right angle is the longest side, called the hypotenuse, while the other two sides are called legs.
Acute triangle: This is a triangle in which all three angles are acute angles, meaning they are less than 90 degrees.
Obtuse triangle: This is a triangle in which one angle is an obtuse angle, meaning it is greater than 90 degrees. The other two angles are acute angles.
The equation that can be used to solve for mº depends on the given information or conditions. If the problem provides the measures of two angles and their sum, then we can use the equation:
A + B + m = 180°
where A and B are the measures of the given angles, and m is the measure of the unknown angle in degrees.
However, if the problem only gives the measures of two angles and their sum is not required, we can use the equation:
A + B = m
where A and B are the measures of the given angles, and m is the measure of the unknown angle in degrees.
Based on the given information in the question, we are only provided with the measures of two angles, 49° and 32°, and there is no indication that their sum is required. Therefore, the correct equation to solve for mº is:
49° = 32° + mº
We can simplify this equation to solve for mº:
49° - 32° = mº
mº = 17°
Therefore, the value of mº is 17°. Answer: (D) 49 = 32° + mº.

The solutions to the original equation are x = 2nπ, where n is an integer.
What is trigonometric identity?A trigonometric identity is an equation that is true for all values of the variables within the domain of the functions involved.
According to question:We can use the trigonometric identity cos(2x) = cos²(x) - sin²(x) to simplify the left-hand side of the equation:
cos(2x)cos(x) - sin(2x)sin(x) = (cos²(x) - sin²(x))cos(x) - 2sin(x)cos(x)sin(x)
Simplifying further using the identity sin(2x) = 2sin(x)cos(x), we get:
(cos²(x) - 3sin²(x)cos(x)) + sin(2x) = 1
Substituting sin(2x) = 2sin(x)cos(x), we get:
cos³(x) - 3sin²(x)cos(x) + 2sin(x)cos(x) - 1 = 0
We can factor this expression as follows:
(cos²(x) - 1)(cos(x) - 2sin(x) + 1) = 0
The first factor has solutions cos(x) = ±1, which means x is an integer multiple of π/2. However, these solutions do not satisfy the original equation, since the left-hand side is always equal to zero.
The second factor gives us the equation cos(x) - 2sin(x) + 1 = 0. We can rewrite this as:
cos(x) + 1 = 2sin(x)
Using the identity sin²(x) + cos²(x) = 1, we can square both sides of this equation to get:
1 + 2cos(x) + cos²(x) = 4sin²(x)
Substituting sin²(x) = 1 - cos²(x), we get:
5cos²(x) - 4cos(x) - 3 = 0
This quadratic equation can be factored as:
(5cos(x) + 3)(cos(x) - 1) = 0
The first factor gives us the solution cos(x) = -3/5, but this is not a valid solution since the cosine function only takes values between -1 and 1.
The second factor gives us the solution cos(x) = 1, which means x is an integer multiple of 2π.
Therefore, the solutions to the original equation are:
x = 2nπ, where n is an integer.

Sumi owns a plant store she wants to put 438 plants in 7 equal rows How many plants will be left over after putting them in do
There will be 4 plants left over after putting them in 7 equal rows.
Calculating the number of left over plantsTo find out how many plants will be left over after putting them in 7 equal rows, we need to divide the total number of plants (438) by the number of rows (7) and then find the remainder.
We can use integer division to find out how many plants will be in each row:
438 ÷ 7 = 62
So each row will have 62 plants.
To find out how many plants will be left over, we can subtract the total number of plants from the product of the number of rows and the number of plants in each row:
438 - (7 x 62) = 438 - 434 = 4

How to calculate for the lateral and total surface area of the triangular prismsThe triangular prisms A and B have two same size triangle faces and two different size rectangle face with a rectangle bottom face.
For 6 and 7;
area of one triangle face = 1/2 × 21 × 9
area of one triangle face = 94.5
area of the two triangle faces = 2(94.5) = 189
area of one smaller rectangle face = 16 × 14 = 224
area of one bigger rectangle face = 17 × 16 = 272
Area of lateral surface area = 188 + 224 + 272 = 685
Area of bottom rectangle face = 21 × 16 = 336
Total surface area of prism A = 685 + 336 = 1021
For 8 and 9;
area of one triangle face = 1/2 × 24 ×
area of one triangle face = 84
area of the two triangle faces = 2(84) = 168
area of one smaller rectangle face = 7 × 5 = 35
area of one bigger rectangle face = 25 × 5 = 125
Area of lateral surface area = 168 + 35 + 125 = 328
Area of bottom rectangle face = 24 × 5 = 120
Total surface area of prism A = 328 + 120 = 448
Therefore, the prism A have lateral surface area = 685 and total surface area = 1021, while the prism B have lateral surface area = 328 and total surface area = 448.

Solve the right triangle. Round your answers to the nearest tenth.
m∠A = _____ degrees
m∠B = _____ degrees
AB = ____ units
(40 points)
Answer:
m∠A = 50°
m∠B = 40°
AB = 15.5 units
Step-by-step explanation:
This is a right trangle, so we can use the Pythagorean Theorem to calculate AB.
AC² + BC² = AB²
AB² = 11.9² + 10²
AB² = 141.61 + 100
AB = √241.61
AB ≈ 15.5 units
Since this is a right triangle, we only need the angle measurement of either m∠A or m∠B to calculate the angle measurement of the other.
I will use sine function to calculate the angle measurements of A and B. Try to use a more precise value for AB than the rounded answer so our angle measurement will be closer to the actual angle.
sin(m∠B) = 10/15.54381
m∠B = sin⁻¹(10/15.54381)
m∠B = 40.04°
Round to nearest tenth, so m∠B = 40°
m∠A + m∠B + 90° = 180°
m∠A + 130° = 180°
m∠A = 50°
The distance from the Earth to the sun is 93 million miles or 93,000,000 miles. How would this number be written in scientific notation?
Answer: To write 93,000,000 in scientific notation, we need to move the decimal point to the left so that there is one non-zero digit to the left of the decimal point.
Counting the number of places we move the decimal point, we get:
93,000,000 = 9.3 x 10^7
Therefore, 93 million miles can be written in scientific notation as 9.3 x 10^7 miles.
Step-by-step explanation:
Write an exponential function whose graph passes through the points (0, –5) and (–2, –20). Then, write a complete sentence describing if the function represents exponential growth or decay and why.
[tex]f(x) = -5 * 2[/tex] is one conceivable exponential function (-x). The coordinates of this function are (0, -5) and (-2, -20).
Because the exponent's base falls between 0 and 1, this function depicts exponential decay. The output of the function decreases at an increasing rate as x rises because the value of 2(-x) shrinks. The function starts at a number larger than zero and lowers with time, as shown by the negative sign. The initial value of -5 denotes the function's beginning point. As a result, when x rises, the function's output gets closer to zero but never quite hits it.
Because to the diminishing nature of the exponent's base, the function [tex]f(x) = -5 * 2(-x)[/tex] generally indicates exponential decay.

In a board game, the cards you draw tell how many spaces to move. Which expression gives the total number of spaces traveled during the 4 turns?
The expression-4 gives the total number of spaces traveled during the 4 turns can be found using integers or its absolute values.
What are integers?
Integers are the collection of negative, positive numbers including zero. The positive integers lie on the right side of the zero on the number line and the negative lie on the left side of zero on number line. The positive numbers are larger than the negative numbers. Also zero is greater than all negative numbers.The absolute value/modulus of any integer is its magnitude without sign. It is the distance of any given integer from zero.
Here the spaces travelled in each turn is given as +7, +2, +5 and -8.
The total sum of the spaces=(+7) + (+2) + (+5) + (-8)
= 7+2+5-8

A 30-foot beam leans against the wall. The beam reaches the wall 16 feet above the ground. What is the measure of the angle formed by the beam and the ground?
(HINT: DRAW THE PICTURE)
The measure of the angle is degrees
(60 points)
the measure of the angle formed by the beam and the ground is approximately 57.76 degrees. the measure of the angle formed by the beam and the ground is approximately [tex]57.76^\circ[/tex] degrees.
What is Right triangles?
A right triangle is a type of triangle that has one angle measuring 90 degrees (a right angle). The side opposite to the right angle is called the hypotenuse, and the other two sides are called the legs.
The Pythagorean theorem is a fundamental concept in mathematics that relates to right triangles, stating that the square of the length of the hypotenuse is equal to the sum of the squares of lengths of two legs.
To solve this problem, we can use trigonometry and the properties of right triangles.
First, let's draw the picture:
In this diagram, we have a right triangle formed by the beam, the wall, and the ground. The height of the triangle is given as 16 feet, and the length of the hypotenuse (the beam) is 30 feet.
We need to find the length of the base of the triangle (the distance between the wall and the bottom of the beam), which we can call d.
Using the Pythagorean theorem, we can find the length of the opposite side of the triangle:
length = √(beam² - wall²)
length = √(30² - 16²)
length = √(900 - 256)
length = √644
length ≈ 25.37 feet
Now we can use the tangent function to find the angle θ:
tan(θ) = opposite/adjacent
tan(θ) = ground/wall
tan(θ) = 25.37/16
tan(θ) ≈ 1.586
To find θ, we need to take the inverse tangent (or arctangent) of 1.586:
[tex]\Theta = tan-1(1.586)[/tex]
[tex]\Theta \approx 57.76^\circ[/tex] degrees
Therefore, the measure of the angle formed by the beam and the ground is approximately [tex]57.76^\circ[/tex] degrees.
