Your model locomotive is 18 inches long. It is an exact model of a locomotive that is 72 feet long. A window on the locomotive is how many times wider than a window on the model?

Answers

Answer 1

Answer: Your model locomotive (x) = 18 inches
72 feet (y)= 72*12 inches
= 864 inches

Ratio = x:y
= 18:864
= 18/864
= 1/48
= 1:48

2) Amanda invests $6,540 in a retirementaccount with a fixed annual interest rate of
5% compounded 6 times per year. What will
the account balance be after 20 years?
A) $16,031.88 B) $17,704.05
C) $15,329.01 D) $16,844.10

Answers

Answer:

B) $17,704.05

Step-by-step explanation:

20 years later is a time in the future so you use Future value formula;

FV = PV* (1+r)^t

where PV= Amount invested in the present = $6,540

r= discount rate = (5% / 6) = 0.833% or 0.00833

t= total duration = 20 *6 = 120

Next, plug in the numbers into the formula;

=6,540* (1+0.00833)^120

=6,540 * 2.707041491

= 17,704.05

Which of the following equations matches the function shown above?

Answers

The equation which matches the function the function shown in the graph is; Choice A: y = 3sin(x - π).

First, the y-intercept of the function can be evaluated at point, x = 0.

At x= 0; we have;

y = 3sin(0 - π).

y = 3sin (-π)

y = -3 × 0

y = 0.

Similarly, when x= π;

y = 3 × 0

y = 0.

Ultimately, the required function is; Choice A; y = 3sin(x - π).
