The function below can be used to calculate the cost of surfing the internet, f(m), which is based on a $10 initial charge and a fee of $.15 per minute, m, till you sign off. f(m)=10+0.15m if jon paid $40, how many minutes did he use the internet? select one: a. 200 b. 267 c. 150 d. 50

Option A

Number of minutes internet is being used is 200 minutes

Solution:

Given that,

The function below can be used to calculate the cost of surfing the internet, f(m) is given as:

f(m) = 10 + 0.15m

Where f(m) is the total cost of surfing the internet

10 denotes the initial charge

m is the number of minutes internet is being used

To find: If Jon paid $ 40 we have to find number of minutes internet is being used

Substitute f(m) = 40 in given function

40 = 10 + 0.15m

0.15m = 40 - 10

0.15m = 30

m = 200

Thus number of minutes internet is being used is 200 minutes

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
