AEFG is not a right triangle, as the sum of the squares of AE and FG does not equal the square of EF. The slope of GH is -11/13.

A triangle is a three-sided polygon with three angles that can be acute, right, or obtuse. It is one of the basic shapes in geometry, and is used in many areas of mathematics, engineering, and construction. Its angles are the basis for trigonometric functions and are the basis for all other shapes in two dimensions. Triangles are also used in architecture and art, as well as for decoration.

No, AEFG is not a right triangle. To prove this, we can use the Pythagorean Theorem. This states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side. In this case, the longest side is the line segment EF, and its length can be calculated using the distance formula:

d(EF) = √((7- (-2))² + ((-8) - 7)²) = √(81 + 81) = √162 = 12.7

The lengths of the two shorter sides, AE and FG, can be calculated in the same way:

d(AE) = √((-2 - (-6)²) + (7 - 3)²) = √(64 + 16) = √80 = 8.94

d(FG) = √((7 - (-6))² + ((-8) - 3)²) = √(81 + 121) = √202 = 14.2

Therefore, the sum of the squares of AE and FG is not equal to the square of EF.

d(AE)²+ d(FG)² = (8.94)²+ (14.2)² = 80.94 + 201.64 = 282.58
d(EF)^2 = (12.7)^2 = 160.49

Since d(AE)² + d(FG)²≠ d(EF)², AEFG is not a right triangle.

The slope of GH can be calculated using the slope formula:

m(GH) = (y2 - y1) / (x2 - x1)

Where (x1, y1) and (x2, y2) are the coordinates of two points on the line. In this case, the coordinates are (7, -8) and (-6, 3).

m(GH) = (3 - (-8)) / (-6 - 7) = 11 / -13 = -11/13

Therefore, the slope of GH is -11/13.

In conclusion, AEFG is not a right triangle, as the sum of the squares of AE and FG does not equal the square of EF. The slope of GH is -11/13.

Where the above conditions are given,  the correct option is: Plan 1 is a better deal for more than 5 cards purchased.

To determine   which pricing plan is a better deal,we need to compare the total cost for a certain number of game cards purchased.

Let's calculate the   total cost for different numbers  of game cards.

For Plan 1  -

- Admission fee  - $5 (fixed)

- Cost per game card  - $1

For Plan 2  -

- Admission fee  - $2.50 (fixed)

- Cost per game card  - $1.50

Now, let's compare the total cost for different numbers of game cards  -

1. If you purchase 1 game card  -

  - Plan 1  - $5 (admission fee) + $1 (cost per game card) = $6

  - Plan 2  - $2.50 (admission fee) + $1.50 (cost per game card) = $4

2. If you purchase 5 game cards  -

  - Plan 1  - $5 (admission fee) + $5 (cost for 5 game cards) = $10

  - Plan 2  - $2.50 (admission fee) + $7.50 (cost for 5 game cards) = $10

3. If you purchase 8 game cards  -

  - Plan 1  - $5 (admission fee) + $8 (cost for 8 game cards) = $13

  - Plan 2  - $2.50 (admission fee) + $12 (cost for 8 game cards) = $14.50

Based on these calculations, we can conclude that  -

- Plan 1 is a better deal for more than 5 cards purchased.

- Plan 2 is a better deal for more than 8 cards purchased.

Therefore, the correct option is  - Plan 1 is a better deal for more than 5 cards purchased.

To calculate the number of votes that Mr. Dyer received, we need to multiply the ratio with the total votes. Mr. Dyer received 1,080 votes.

Ratio of votes = 4:3:2

Total votes = 4 + 3 + 2 = 9

Total votes cast = 2,700

Mr. Dyer's votes = (4/9) x 2,700 = 1,080 votes

The ratio of votes cast for Mr. Dyer, Ms. Frau and Mr. Borak was 4:3:2 respectively. This means that for every 9 votes cast, 4 votes were for Mr. Dyer, 3 votes were for Ms. Frau and 2 votes were for Mr. Borak. Since none of the 2,700 voters cast more than one vote, the total votes cast for each candidate would be 2,700. To calculate the number of votes that Mr. Dyer received, we need to multiply the ratio with the total votes. Therefore, Mr. Dyer received 1,080 votes (4/9 x 2,700).

The scatterplot between a predictor variable and an outcome with a non-linear relationship would not form a straight line, but rather a curved or nonlinear shape.

In linear regression, we assume that there is a linear relationship between the predictor variable and the outcome. However, this assumption may not hold in all cases, and there may be cases where the relationship between the two variables is not linear.

In such cases, a straight line may not be a good fit for the data, and a non-linear model may be more appropriate. In a scatterplot, a non-linear relationship would be indicated by a curve or a nonlinear shape rather than a straight line.

Examples of non-linear relationships include exponential, logarithmic, and polynomial relationships. It is important to identify and account for non-linear relationships when modeling data to ensure accurate and valid results.

The values for compound interests are -

Investment 1 - PV = $500, r = 0.1, m = 1, t = 40, FV = $22629.6277

Investment 2 - PV = $500, r = 0.11, m = 1, t = 40, FV = $32500.4336

Investment 2 - PV = $500, r = 0.12, m = 1, t = 40, FV = $46525.4852

What is Compound Interest?

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

The Compound Interest Formula is: FV = PV(1+r/m)^mt

• FV is the future value of the investment

• PV is the present value of the investment (the principal you start with, your first deposit)

• r is the annual rate of interest as a decimal (10% is expressed as the decimal 0.1)

• m is the number of times per year the interest is compounded (monthly=12, annually=1

etc.). Interest will be compounded once a year (1).

• t is the number of years you leave it invested (in this case, 40)

The present value of investment is = $500

The rate of interest is 10%, 11% and 12%.

The time period in years is 40 years.

For the 1st investment, PV = 500, r = 0.1, m = 1 and t = 40

Apply the formula for compound interest -

FV = PV(1+r/m)^mt

Substitute the values into the equation -

FV = 500(1+0.1/1)^1(40)

FV = 500(1.1)^40

FV = 500 × 45.25925

FV = 22629.6277

So, the final value is $22629.6277.

For the 2nd investment, PV = 500, r = 0.11, m = 1 and t = 40

Apply the formula for compound interest -

FV = PV(1+r/m)^mt

Substitute the values into the equation -

FV = 500(1+0.11/1)^1(40)

FV = 500(1.11)^40

FV = 500 × 65.00086

FV = 32500.4336

So, the final value is $32500.4336.

For the 3rd investment, PV = 500, r = 0.12, m = 1 and t = 40

Apply the formula for compound interest -

FV = PV(1+r/m)^mt

Substitute the values into the equation -

FV = 500(1+0.12/1)^1(40)

FV = 500(1.12)^40

FV = 500 × 93.05097

FV = 46525.4852

So, the final value is $46525.4852.

The probability that x is between 11 and 35 is approximately 0.6826 or 68.26%.

To find the probability that x is between 11 and 35, we need to standardize the values using the formula z = (x - μ) / σ, where μ is the mean and σ is the standard deviation.
For x = 11, z = (11 - 23) / 12 = -1.00
For x = 35, z = (35 - 23) / 12 = 1.00
Using a standard normal distribution table or calculator, we can find the probability of z being between -1.00 and 1.00, which is approximately 0.6827. Therefore, the probability that x is between 11 and 35 is approximately 0.6827.
To find the probability that x is between 11 and 35 for a normally distributed random variable with a mean of 23 and a standard deviation of 12, you'll need to use the z-score formula and a standard normal distribution table.
First, convert the given values of 11 and 35 to their respective z-scores using the formula:
z = (x - mean) / standard deviation
For 11: z1 = (11 - 23) / 12 = -1
For 35: z2 = (35 - 23) / 12 = 1
Now, refer to a standard normal distribution table to find the probabilities corresponding to z1 and z2.
P(z1) ≈ 0.1587
P(z2) ≈ 0.8413
Finally, subtract the two probabilities to find the probability that x lies between 11 and 35:
P(11 < x < 35) = P(z2) - P(z1) = 0.8413 - 0.1587 = 0.6826
So, the probability that x is between 11 and 35 is approximately 0.6826 or 68.26%.

Caroline saved $3. 84 on a discounted item that was marked down 15% off of the original price of the item. What was the original price of the item before the discount, the original price of the item was $4.52 before the discount.

Let the original price of the item be $x. The item was marked down by 15%, so the discounted price is 85% of the original price. This is equivalent to saying that the discounted price is 100% - 15% of the original price. Mathematically, we can write this as: 0.85x = discounted price

Since Caroline saved $3.84 on the discounted item, we can write an equation that equates the amount she paid for the item to the discounted price minus the amount she saved. Mathematically, we can write this as:

0.85x - 3.84 = amount paid

Solving for x (the original price) requires us to rearrange the equation to isolate x. Mathematically, we can write this as:

x = (amount paid + 3.84) / 0.85

Substituting in the given values gives: x = ($0.00 + $3.84) / 0.85 = $4.52

The formula for the arc length of the function f(x) in the interval [a, b] is given by the formula,

L = ∫a^b sqrt[1 + (f '(x))^2]dx

Given the function, y= 3/2 (x-1)^(3/2),

the derivative is given by, y' = (3/2) * (3/2) * (x - 1)^(1/2) = (9/4)(x - 1)^(1/2).

Substitute the derivative in the formula to obtain the arc length as,

L = ∫1^4 sqrt[1 + (9/4(x - 1)^(1/2))^2]dxL = ∫1^4 sqrt[1 + 81/16(x - 1)]dxL = ∫1^4 sqrt[(81x + 13)/16]dx

Using the substitution, u = 81x + 13, du = 81dx, the limits change to u(1) = 94, u(4) = 337

Therefore, the integral is,∫(94/16)^(337/16) sqrt(u)/81 du = (16/81)[(2/3)u^(3/2)](94/337) = 8/27 (337^(3/2) - 94^(3/2))

The arc length in decimal approximation is given by,8/27 (337^(3/2) - 94^(3/2)) = 55.632 (approx.)

Therefore, the exact arc length is 8/27 (337^(3/2) - 94^(3/2)) and the decimal approximation is 55.632.

Hence, the required answer is "Compute the arc length of the graph of y= 3/2 (x-1)^(3/2),1≤x≤4.
