I'm not sure what he answer to the second part is, but for the first part, find the area of the whole figure, so multiply 15.5 by 10.4 to get 161.2. then find the area of the semi circles and since there are 2 of them, it is one full circle so use the formula for the area of a circle, A=(pi)r^2, to find the area of the semicircles. when you substitute and solve, you get about 84.95. then subtract the semicircles' area from the rectangle's area to get 76.25.

The table shows the temperatures in degrees Celsius, y, inside a shed at x hours past noon. The maximum and minimum temperatures

kolbaska11 [484]

Answer:

y = 3 cos (pi/12x - pi/4) + 17

Step-by-step explanation:

First find the average temperature which is 20 + 14/2 = 17

Find the amplitude

20 - 17 = 3

This means that that at noon, the shift is 3hrs past

the best equation that represents this scenario is $y = 3 cos (\frac{\pi}{12}x - \frac{\pi}{4}) + 17$

in addition to dog walking on Tuesday Eric made $45 dog sitting at one of his customers homes if he made $168 on Tuesday right i

Rus_ich [418]

Since we don't know how much Eric makes per dog, let's let x represent that value. Let's also let y represent our answer.

First, let's consider the two numbers we KNOW will be in the equation. The 56 that Eric made dog sitting and the 168 he made in total on Tuesday. Now, we're going to need to use subtraction and division in this equation.

(168 - 45) ÷ x = y

Hope this answer helped you out. :)
