A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(

gavmur [86]

We have the following function:
f(t) = −16t2 + 34t + 546
By definition, the average rate of change is:
Avr = (f (t2) - f (t1)) / (t2 - t1)
We have then:
For t1 = 5:
f (5) = -16*(5)^2 + 34*(5) + 546
f (5) = 316
For t2 = 5:
f (7) = -16*(7)^2 + 34*(7) + 546
f (7) = 0
Substituting values:
Avr = (0 - 316) / (7 - 5)
Avr = -158
Answer:
The average rate of change of f (t) from t = 5 seconds to t = 7 seconds is -158 feet per second.

a recent survey determained that 7 out of 9 students eat school lunch at least once a week. if 54 students were surveyed how man

Setler [38]

Answer:

12 students

Step-by-step explanation:

Given

$Students = 54$

Required

Determine the number of students that eat lunch once a week

In Sets;

If out of 9, at least 7 eats one a week then

9 - 7 eats lunch once a week

$9 - 7 = 2$

<em>In other words;</em>

2 out of 9 students eat lunch once a week

Number of students in this category is then calculated as thus;

$Number = \frac{2}{9} * 54$

$Number = \frac{2 * 54}{9}$

$Number = \frac{108}{9}$

$Number = 12$
