The linear equation that passes through the given points is:

y + 9 = -10*(x - 1)

A general linear equation that passes through two points (x₁, y₁) and (x₂, y₂) has a slope given by:

a = (y₂ - y₁)/(x₂ - x₁)

Then using any of these points we can write the line as:

y -  y₁ = a*(x - x₁)

Here the points are (1, -9) and (-10, 101), then the slope is:

a = (101 + 9)/(10 - 1) = 110/-11 = -10

And using the point (1, -9) we can write the line as:

y + 9 = -10*(x - 1)

The correct equation to isolate principal, P, is:

Simple interest refers to the interest that is earned on an initial amount of money, known as the principal, over a fixed period of time. It is called "simple" because it is calculated based only on the initial principal amount and does not take into account any interest earned on the interest itself, which is known as compound interest.

To isolate principal, P, we need to rearrange the given formula as follows:

[tex]A - P(1 + rt) =[/tex] Interest earned on principal (I)

The interest earned on the principal (I) is given by:

[tex]I = Prt[/tex]

Now, we can rewrite the above formula as:

[tex]A = P + I[/tex]

Substituting the value of I, we get:

[tex]A = P + Prt[/tex]

Now, we can isolate P by subtracting Prt from both sides:

[tex]A - Prt = P[/tex]

Therefore, the correct equation to isolate principal, P, is:

[tex]P = (A - Prt)[/tex]

The correct equation to isolate P is c. P = A/(1 + rt)

Simple interest is the term used to describe the interest that is accrued over a predetermined amount of time on an initial sum of money, known as the principal. It is known as "simple" interest because it is computed just using the initial principal sum and ignores any interest that has been earned on top of the interest itself, a concept known as compound interest.

The formula for the final amount earned using simple interest is A = P(1 + rt), where A is the total amount at the end of t years, P is the principal amount, r is the interest rate, and t is the time in years.

To isolate P, we can rearrange the formula as:

A = P(1 + rt)

Divide both sides by (1 + rt):

A/(1 + rt) = P

Therefore, the correct equation to isolate P is:

c. P = A/(1 + rt)

How To Calculate Cost Of Living

Subtract the index of your current city from the index of the city you want to move to: 115.1 - 90.9 = 24.2.

Divide the resulting difference by the index of your current city: 24.2 ÷ 90.9 = 0.266.

Multiply the resulting quotient by 100 to get the percentage: 0.266 x 100 = 26.6%

The probability that a chosen point, in the figure lies in the shaded region is 3.18.

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%

The probability of the point chosen in the shaded region is calculated by the formulae

Probability = [tex]\frac{Area of shaded region}{Total area}[/tex]

To find the total area we need to find the area of a triangle and the area of a semicircle.

Area of triangle = 1/2 * Base * Height

                          = 1/2 * 15 * 6

                          = 45

Area of semicircle =  [tex]\frac{\pi r^{2} }{2}[/tex]

                              = [tex]\frac{\pi (3)^{2} }{2}[/tex]

                              =14.13

Therefore the probability that chosen point = [tex]\frac{45}{14.13}[/tex] = 3.18

36/150 = x/1500

x = (36/150) * 1500

x = 360

For Christy:

42/150 = x/1500

x = (42/150) * 1500

x = 420

For Celina:

22/150 = x/1500

x = (22/150) * 1500

x = 220

Therefore, Henry is predicted to receive 360 votes, Christy is predicted to receive 420 votes, and Celina is predicted to receive 220 votes for the president’s position.

Using the equations we know that the square should be finished by adding 9 to both sides.

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others.

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.

So, write the equation so that the terms with x are on the left and the constants are on the right:

x² – 6x = 5

Ensure that the x2 term's coefficient is 1:

x² – 6x = 5

Including a phrase on both sides will complete the left side's square. The x term's coefficient is multiplied by two and squared to achieve this.

To make the equation equal on both sides, add the same amount to the right side.

x² – 6x + 9 = 5 + 9

(x-3)² = 14

Therefore, using the equations we know that the square should be finished by adding 9 to both sides.

Step-by-step explanation:

The value of x in the tangent angle formed by the intersecting chords on the circle is 8.

The value of x is calculated by setting up equation for the sum of angles in a circle in order to obtain the value of the opposite arc angle (arc WX) as shown below.

arc WX + arc WV + arc VX = 360 ( sum of angles in a circle)

arc WX + 96⁰ + 64⁰ = 360⁰

arc WX + 160 = 360

arc WX = 360 - 160

arc WX = 200

The value of angle WVX is equal to half of arc angle WX (based on intersecting chord theorem).

m ∠WVX = ¹/₂ arc WX

12x + 4 = ¹/₂ (200)

12x + 4 = 100

12x = 100 - 4

12x = 96

x = 96/12

Using the area formula,

Area of the prism = 40mm².

Define area?

The word "area" designates a vacant region. The length and width of a form are used to calculate its area. The units of unidimensional length are feet (ft), yards (yd), inches (in), etc. Yet, the area of a shape is a two-dimensional quantity. Measurements like square inches (in²), square feet (ft²), square yards (yd²), etc. are used to measure anything in a square.

In the figure,

We have 2 equal rectangles and 2 equal triangles.

Now dimensions of the rectangles, l = 4mm and b = 3mm.

Area of 2 rectangles = 2 × 4 × 3

= 24mm².

Height of triangle, h = 4mm and base, b = 4mm.

Area of 2 triangles = 2 × 1/2 × b × h

= 4 × 4

= 16mm².

Therefore, total area of the prism = 24 + 16 = 40mm².

Based on the amount predicted to be spent, the hypotheses Null Hypothesis = $1,007.24 and Alternate Hypothesis ≠ $1,007.24

The null hypothesis, or H0, in statistics science is the exact reverse of what the researcher wants to investigate. Generally, unless there is compelling proof to the contrary, the null hypothesis is taken to be correct. Another theory that will demonstrate the area one wants to investigate and be reflected by H1 must be developed.

The forecast is confirmed by the null hypothesis, which in this instance is that the typical consumer will indeed spend $1,007.24. According to the Alternate Hypothesis, the predicted occurrence won't occur, so in this instance, the shopper wouldn't spend $1,007.24.

Answer: D Mario owes the bank a little less than $50

The fact that PC is less than 50% indicates a higher probability of underage.

However, without additional information on the costs associated with overage and underage, we cannot determine which cost is higher.

From the information given in the student question, it is clear that the probability of underage (PC) is less than 50%, as indicated by the shaded area under the graph.

To determine whether the cost of overage or the cost of underage is higher, follow these steps:
1. Identify the costs associated with overage and underage in the given context. Overage cost refers to the cost incurred when the inventory is higher than demand, while underage cost refers to the cost incurred when the inventory is lower than demand.
2. Analyze the graph or data provided to compare the costs of overage and underage. Since the student question does not provide any specific data or graph, we cannot accurately determine which cost is higher based on the given information.
3. Interpret the results. If the cost of overage is higher than the cost of underage, this means that having excess inventory is more expensive than having insufficient inventory.

Conversely, if the cost of underage is higher than the cost of overage, this means that not having enough inventory is more expensive than having excess inventory.

Answer:

∠1 = 126°

∠4 = 54°

∠7 = 126°

Step-by-step explanation:

Since line p and line q are parallel lines we can use the angle relations to find the missing angle measures.

∠1 and ∠3 are alternate and congruent, so their measures are equal and 126° each.

∠4 and ∠3 are making a straight line and are supplementary angles, so their sum is adding up to 180°.

To find ∠4 we need to subtract 126 from 180:

180 - 126 = 54°

∠7 and ∠3 are corresponding angles and so they are equal in measurement and 126° each.

The limit of the given function as x approaches infinity is 2.

Infinity is a concept used in mathematics to represent a quantity that is unbounded or without limits. It is often used to describe a value or set of values that increases or decreases indefinitely without ever reaching a final value.

To find the limit of the given function as x approaches infinity, we need to determine the behavior of the function as x becomes very large (positive or negative).

Let's examine the expression inside the limit as x approaches infinity:

StartFraction 4 - 3x + x² Over 2x² + 1 EndFraction

As x approaches infinity, the highest power term in the numerator and denominator dominates. In this case, the term x² dominates in the numerator and denominator. So we can simplify the expression by dividing both numerator and denominator by x²:

Start Fraction 4/x² - 3/x + 1 Over 2 + 1/x² End Fraction

As x approaches infinity, both the terms 3/x and 1/x² become very small and can be ignored. Therefore, the expression approaches:

Start Fraction 4/x² - 0 + 1 Over 2 + 0 End Fraction

which simplifies to:

Start Fraction 4 Over 2 End Fraction = 2

what is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.

To solve this problem, we can use the equation:

F = m*a

where F is the force applied, m is the mass of the object, and a is the acceleration.

We can rearrange this equation to solve for acceleration:

a = F/m

Using this equation, we can find the acceleration of the golf ball:

a = 450N / 0.025kg = 18000 m/s²

Next, we can use the equation:

v = v0 + a*t

where v is the final velocity, v0 is the initial velocity (which we'll assume is 0 m/s), a is the acceleration, and t is the time.

We know the acceleration and the time, so we can solve for the final velocity:

v = 0 + (18000 m/s²) * 0.012 s

v = 216 m/s

Therefore, the velocity of the golf ball will increase by 216 m/s.
