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 $y = 3 cos (\frac{\pi}{12}x - \frac{\pi}{4}) + 17$

Which expression is equivalent to 2 (t-4) +1. A 2t-5 B.2t-7 C. 2t-9 D. 2t -3

seraphim [82]

Answer: 2t + -8

Step-by-step explanation: Let's simplify this problem using the distributive property.

The first thing we want to do is change this minus to plus a negative.

Now we can distribute or multiply this 2 times

each of the terms inside the set of parentheses.

So we get 2(t) + 2(-4) and this simplifies to 2t + -8.

2t + -8 is the same thing as 2t -8.
