David is keeping track of the internal temperature of a chicken he is cooking. The table below

Nataly_w [17]

Using the average rate of change, it is found that the average rate is of:

(1) 2.1 °F per minute

<h3>What is the average rate of change of a function?</h3>

It is given by the <u>change in the output divided by the change in the input</u>.

In this problem:

At 15 minutes, the temperature was of 90ºF.

At 45 minutes, the temperature was fo 153ºF.

Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:

r = 63/30 = 2.1 °F per minute.

Leni [432]

Answer: The sunflower be 50 inches tall after 6 weeks.

Total height of sunflower in w weeks = 20+1.5 w,

Step-by-step explanation:

Given: In the beginning, the sunflower was 20 inches tall.

The sunflower then began to grow at a rate of 1.5 inches per week.

Then, total height of sunflower in 6 weeks = 20+1.5 ×20, where 1.5 ×20= growth in 6 weeks

= 20+30

= 50 inches

So, the sunflower be 50 inches tall after 6 weeks.

Let w = number of weeks, then

Total height of sunflower in w weeks = 20+1.5 w, where 1.5 w= growth in w weeks.

nika2105 [10]

Answer:

Kathy would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.

Step-by-step explanation:

Kathy ran the 400-meter dash in 60.48 seconds, so if she now divided that time into 8 equal time segments we have:

$t = 60.48 s$

By dividing the above equation into 8:

$t = \frac{60.48 s}{8} = 7.56 s$

Hence, she would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.

I hope it helps you!
