Question
Find the surface area of the regular pyramid.
Answer:
Surface area:The sum of all the sides to a figure.Given that the area of the base is 440.4, all we would need to find out is the sum of all the areas of the triangles surrounding it.
Formula for area of a triangle:
A = BH x 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 simply means to divide the product of those two lengths(base and height) by 2.
Plug in what we know:-
A = BH x 1/2
A = 16(20) x 1/2
A = 320 x 1/2
A = 320/2
A = 160 mm is the area of one triangle, but we want to know the area of all 5 triangles, so;
160(5)
= 800 mm is the area of all the triangles.
Now add the base area to the area of all the triangles.
440.4 + 800
= 1,240.4 mm.
Therefore the surface area of this pyramid is 1,240.4 mm.
Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
A = 1/2 x base x slant height
For the 5 triangles,
A = 5 x 1/2 x base x slant height = 1/2 x 5 x slant height
Substitute values,
A = 5 x 1/2 x 16mm x 20mm = 800 mm²
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²

Answer:
x=5
Step-by-step explanation:
6x-3=3x+12. Subtract 3x from both sides.
3x-3+12. Add 3 to both sides.
3x=15. Divide 3 from both sides.

What happens to a number when you multiply by 1000? Why does this happen?
Answer:
the number will get 1000 times larger than its original number or 3 zeroes will be added in the last place of the number
Step-by-step explanation:
let's say x=5,
if we multiply 5 by 1000 it becomes 5000 (it is 1000 times more or larger than its orignal number and 3 zeroes are added in 5000).

Step-by-step explanation:
i)
Consider the exponential equation
[tex]y = a {e}^{bt} [/tex]
Now Substitute these points to get a and b value
(0,37000) , (1,20350)
[tex]37000 = a \times {e}^{b \times 0} [/tex]
[tex]37000 = a \times 1[/tex]
Hence a=37000
Now Substitute t=1
[tex]20350 = 37000 \times {e}^{b \times 1} [/tex]
[tex] \frac{20350}{37000} = {e}^{b} [/tex]
[tex]0.55 = {e}^{b} [/tex]
[tex]b = log_{e}(0.55) = - 0.5978[/tex]
b≈(-0.6)
[tex]y = 37000 {e}^{ - 0.6t} [/tex]
is the required equation
ii)
[tex]y = 37000 {e}^{ - 0.6 \times 0.4} [/tex]
[tex]y = 37000 {e}^{ - 0.24} [/tex]
iii) it decreases by a factor of
[tex] {e}^{0.6} [/tex]
every decade
So the factor by which the price of car decreases every year is
[tex] {e}^{ \frac{0.6}{10} } [/tex]
as 1year =1/10 decade
Hence the required factor
[tex] {e}^{0.06} [/tex]

find the area of the shaded region. Use the formula A= pie r^2 to find the area of a circle
Answer:
(π6x+21π)m²
Step-by-step explanation:
Solution,
For small circle
radius(r)=x+2
Area(A1)=πr²
Area(A1)=π×(x+2)²
Area(A1)=π×(x²+4x+4)
Area(A1)=πx²+π4x+4π
For big circle
radius(r)=x+5
Area(A2)=πr²
Area(A2)=π×(x+5)²
Area(A2)=π×(x²+10x+25)
Area(A2)=πx²+π10x+25π
Again,
Area of shaded part=A2-A1
Area of shaded part=πx²+π10x+25π-(πx²+π4x+4π)
Area of shaded part=πx²+π10x+25π-πx²-π4x-4π
Area of shaded part=π6x+21π

Answer:
171 Square Feet
Step-by-step explanation:
We first cut the figure up into smaller parts...
we then use the formula (L x W = A) to find the area
L = Lenth
W = Width
the first rectangle (1)...
15 x 5 = 75
the second figure (2)...
8 x 9 = 72
the third figure (3)...
6 x 4 = 24
now we have to add up all the values to find the area of the entire figure...
75 + 72 + 24 = 171

Complete the first 4 steps for graphing the quadratic function given. (Use ^ on the keyboard to indicate an exponent.) Then graph the quadratic function. Be sure to label the axes and vertex.
y = -x^2 - 4x - 3
( Thanks in advance!! )
The quadratic equation y = -x^2 - 4x - 3 has a degree of 2
The vertex of the function is (-2,1)
How to graph the function?The equation of the function is:
y = -x^2 - 4x - 3
Differentiate
y' = -2x - 4
Set to 0
-2x - 4 = 0
Solve for x
x = -2
Substitute -2 for x in y = -x^2 - 4x - 3
y = -(2)^2 - 4(-2) - 3
y = 1
The above means that the vertex of the function is (-2,1)

There are 9 balls numbered 1 through 9 placed in a bucket. What is the probability of reaching into the bucket and randomly drawing four balls numbered 6, 9, 8, and 7 without replacement, in that order? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Using the permutation formula, as the order is important, it is found that there is a 0.000331 probability of selecting the balls in the desired order.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem, 4 balls will be taken from a set of 9, hence the total number of outcomes is:
[tex]P_{9,4} = \frac{9!}{5!} = 3024[/tex]
The desired outcome is only one, hence the probability is given by:

Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°. Which of the following is a possible way to classify the triangle by side and angle measurements?
A. Obtuse and isosceles
B. Acute and scalene
C. Obtuse and equilateral
D. Acute and equilateral
Answer:
Acute and Scalene
Step-by-step explanation:
The measurments of the triangle are all almost equal and all the angles are less than 90 degrees, so all of them are acute angles. The scalene triangle has almost all equal sides.
The possible way to classify the triangle by side and angle measurements is,
⇒ Acute and scalene.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°.
Since, All the angles are less than 90 degree.
Hence, It shows the Acute angle.
Here, Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm.
Clearly, All the sides of triangle are not same in length.
Thus, It shows scalene.
