Solve. m - 15 = 20 m =

Fittoniya [83]

$\text{Hello There!}$

$\text{We are going to need to isolate the variable}$

$m - 15 = 20$

$\text{Add 15 to both sides.}$

$\text{We do this because we need to perform inverse operations to find}$ $\text{the value of the variable.}$

$m - 15 + 15 = 20 + 15 = 35$

$\fbox{Therefore, your answer is going to be 35.}$

$\rule{300}{1.5}$

The formula

son4ous [18]

Answer:

The truck travel must to have a constant speed of $22.06\ ft/sec$

Step-by-step explanation:

we have

$d=1.3t^{2}+t+2$

where

d expresses a car's distance in feet

t is the number of seconds

Find the distance d for t=8 sec

$d=1.3(8)^{2}+8+2=93.2\ ft$

Find the distance d for t=8.2 sec

$d=1.3(8.2)^{2}+8.2+2=97.612\ ft$

The total distance in this interval of 0.2 sec is

$97.612-93.2=4.412\ ft$

Find the speed of the car

Divide the total distance by the time

$4.412/0.2=22.06\ ft/sec$

therefore

The truck travel must to have a constant speed of $22.06\ ft/sec$
