The reference angle is given as 45 degrees

the angle is in the 4th quadrant

sin 315 = - sqrt(2) / 2

cos 315 = sqrt(2) / 2

We have θ = 315

θ is seen to lie between 270 degrees and 360 degrees in the 4th quadrant

In the fourth quadrant the reference angle has been solved by:

360 - θ

360 - 315

= 45 degrees

The reference angle is 45 degrees

sin 315 = sin( 360 - 45)

= [tex]-\frac{\sqrt{2} }{2}[/tex]

= - sqrt(2) / 2

cos 315 = cos (360 - 45)

= [tex]\frac{\sqrt{2} }{2}[/tex]

= sqrt(2) / 2

Hence, in response to the provided question, we can say that As a result,  equation  A(1,2) and A'(5,12) are not dilations.

An algebraic equation is a method of connecting two quotes by using the equals symbol (=) to express equality. In algebra, an explanation is a definitive expression that verifies the equivalency of two formula. For example, the identical character divides the numbers 3x + 5 and 14. A linear equation might be used to recognize the connection that existing between the texts written on separate sides of a letter. The product and application both frequently the same. 2x - 4 equals 2, for example.

To evaluate if the points A(1,2) and A'(5,12) reflect a dilation, we must first determine the dilation's scale factor.

Let's use the given points to compute the scale factor:

(length of A' A) / scale factor (length of A)

A's length A [tex]=\ sqrt[(5-1)2 + (12-2)2] = \sqrt[16^2 + 10^2] =\ sqrt(296) (296)[/tex]

A's length is one.

[tex](\sqrt(296)) / 1\\\sqrt(x) = scale factor (296)[/tex]

As a result, the scaling factor is not an integer. That is, the transformation from point A to point A' is not a dilation with a whole number scale factor.

As a result, A(1,2) and A'(5,12) are not dilations.

Answer:

the sum of a+b+c is 56.

Step-by-step explanation:

If a:b:c = 1:3:4 and c = 28, we can find the values of a and b using the ratios.

Since a:b:c = 1:3:4, we can write:

a = x, b = 3x, c = 4x

where x is some constant of proportionality.

We are given that c = 28, so we can substitute this value to get:

4x = 28

Solving for x, we get:

x = 7

Therefore, a = x = 7 and b = 3x = 21.

The sum of a, b, and c is:

a + b + c = 7 + 21 + 28 = 56

So the sum of a+b+c is 56.

The sine rule (also known as the law of sines) is a mathematical formula that relates the sides and angles of a triangle. Specifically, it relates the ratios of the lengths of the sides of a triangle to the sine of the opposite angles.

By the use of the sine rule;

a/Sin A = c/Sin C

Sin C = cSin A/a

C = Sin-1(cSin A/a)

C = Sin-1(7.8 * sin 66.4/9.2)

C = 50.98°

B = 180 - (50.98° + 66.4)

B = 62.62°

Then;

a/Sin A = b/Sin B

9.2/Sin66.4 = b/Sin 62.62

b = 9.2 * Sin 62.62/Sin66.4

b = 9.2 * 0.89/0.92

Answer:

To find the x and y intercepts, we set x and y to zero respectively:

x-intercept: setting y = 0 gives us 6/(x^2 - 5x - 6) = 0, which has no real solutions.

y-intercept: setting x = 0 gives us s(0) = 6/(-6) = -1.

To find the vertical asymptotes, we set the denominator equal to zero and solve for x:

x^2 - 5x - 6 = 0

(x - 6)(x + 1) = 0

This gives us two vertical asymptotes at x = 6 and x = -1.

To find the horizontal asymptote, we need to look at the behavior of the function as x approaches infinity and negative infinity. As x becomes very large in magnitude, the terms involving x^2 become much larger than the terms involving x or the constant term, and so we can ignore those terms. This gives us:

s(x) ≈ 6/x^2 as x → ±∞

Therefore, the horizontal asymptote is y = 0.

In summary:

x-intercept: none

y-intercept: (0, -1)

vertical asymptotes: x = 6 and x = -1

horizontal asymptote: y = 0

The balance in the account after 4 years is $3,376.50.

The balance in the account after 25 years is $16,050.07.

The tractor will be worth $9,449.11 after 3 years.

All posted credit and debit transactions are included in your account balance. It's the balance in your account before any pending charges are subtracted. The amount that can be used for withdrawals or purchases is your accessible balance.

1. We can use the formula A = P(1 + r/n) to determine the account balance after 4 years with a $3,000 principal receiving 3% compounding annually (nt)

where A represents the balance, P represents the principal, r represents the yearly interest rate, n represents the number of times interest is compounded annually, and t represents the passage of time in years.

By typing in the indicated values, we get:

A = 3000(1 + 0.03/1)^(1*4)

A = 3000(1.03)^4

A = 3000(1.1255)

A = $3,376.50

Thus, $3,376.50 remains in the account after 4 years.

2. We can once more apply the formula: A = P(1 + r/n) to determine the account balance after 25 years with a $2,000 principal, receiving 7% compounding semi-annually (nt)

Then then, it's a case of the same thing happening again.

By typing in the indicated values, we get:

A = 2000(1 + 0.07/2)^(2*25)

A = 2000(1.035)^50

A = $16,050.07

Thus, the account has a balance of $16,050.07 after 25 years.

3. Considering that the tractor loses 15% of its value per year, we can apply the formula A = P(1 - r)t to determine how much it will be worth after three years.

where A represents the final value, P the starting point, r the depreciation rate, and t the passage of time in years.

By typing in the indicated values, we get:

A = 14340(1 - 0.15)^3

A = 14340(0.85)^3

A = $9,449.11

The tractor will therefore be valued $9,449.11 after three years.

Answer: B 14.0

Step-by-step explanation:

Answer:

Each student received 40/37 of a pizza slice.

Step-by-step explanation:

To find the fraction of the pizza each student received, we can start by finding the total number of pizza slices. Since each pizza was shared equally among 37 students, we can multiply the number of pizzas (5) by the number of slices in each pizza to get the total number of slices:

Total number of slices = 5 pizzas x 8 slices per pizza = 40 slices

Next, we can divide the total number of slices by the number of students to get the number of slices each student received:

Number of slices per student = 40 slices ÷ 37 students

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1:

Number of slices per student = 40/37 slices

Therefore, each student received 40/37 of a pizza slice.

Hope this helps! I'm sorry if it doesn't. If you need more help, ask me! :]

To find the fraction of the pizza each student received, we need to divide the total number of pizzas by the total number of students:

5 pizzas ÷ 37 students = 5/37 pizzas per student

Therefore, each student received 5/37 of a pizza.

Step-by-step explanation:

Now, Distance= 165 km and we got velocity= 47.5km/hour

                          = 47.5 =165/time

Time taken =      165/47.5= 3hours and 50 minutes.

Therefore, Time taken to remaining 165 km of her trip is 3hours and 50 minutes.

We can be 95% confident that the true population mean difference between the two samples falls within the range of 0.374 to 0.562

To construct a 95% confidence interval for the data, we need to calculate

The formula for the mean difference is:

x₁ - x₂ = 3.4123 - 2.9442 = 0.4681

The formula for the standard deviation of the differences is:

sD = √[(s₁²/n₁) + (s₂²/n₂)]

SD = √[(1.7458²/57) + (2.0382²/57)]

SD = 0.3555

The margin of error is calculated using the following formula:

ME = t * (sD / √(n))

where t is the critical value for a 95% confidence interval with 56 degrees of freedom

So, we have

ME = 2.003 * (0.3555 / √(57))

ME = 0.0943

Finally, we can calculate the upper and lower bounds of the confidence interval:

CI = (x₁ - x₂) ± ME

CI = 0.4681 ± 0.0943

CI = (0.4681 - 0.0943, 0.4681 + 0.0943)

CI = (0.3738, 0.5624)

Approximate

CI = (0.374, 0.562)

Thus, the 95% confidence interval for the mean differences is (0.374, 0.562), rounded to three decimal places.
