alisha [4.7K]

Answer:

Emily have 33 cookies.

Step-by-step explanation:

Given that:

Batches of cookies baked = 3

Number of cookies in each batch = 13

Total number of cookies = 3 * 13 = 39 cookies

She ate 2 cookies.

Remaining = 39 - 2 = 37 cookies

She gave 10 to her neighbor

Remaining = 37 - 10 = 27 cookies

1 batch = dozen cookies

half batch = 6 cookies

Total cookies = 27 + 6 = 33 cookies

Hence,

Emily have 33 cookies.

aliina [53]

The graph shows the height h, in feet, of s football at time t, in seconds, from the moment it was kicked at ground level.

We are supposed to find the average rate of change in height from t=1.5 seconds to t=1.75 seconds.

Average rate of change in height=\frac{\text{Change in Height}}{\text{Time taken}}\\

As we can see from the the change in distance for the time interval 1.5 second to 1.75 second=12-7=5

and time=1.75-1.5=0.25

Average rate of change in height=\frac{5}{0.25}\\=20ft/sec

Hence Required Rate of change is -20 ft/sec, because its falling(In the direction of negative y-aixs)

The expression - 370 + 15z represents a submarine that began at a depth of 370 feet below sea leve
Aleks [24]

Answer:

<em>The depth of the submarine was 295 feet</em>

Step-by-step explanation:

<u>Function Modeling</u>

The following expression models the depth of a submarine that began at -370 m and ascended at 15 ft/minute:

d = -370 + 15z

Where z is the time in minutes.

We are required to find the depth of the submarine at t=5 minutes. Substituting t=5 into the function model:

d = -370 + 15(5)

d = -370 + 75

d = -295 feet

The depth of the submarine was 295 feet
