A bullet train travels at a speed of 365km/h. In August 2001, Singapore’s record for the man’s sprint was set at 10.37 second. H

Vera_Pavlovna [14]

Answer:

It is 91.01 m/s faster than the Singaporean sprinter

Convert km/hr to m/s

U get 101.38m/s (speed of bullet train)

Speed of the Singaporean sprinter is 10.37m/s

So subtracting the train speed from the sprinter's speed,

101.38 - 10.35= 91.01m/s

Gabriel models the volume of a popcorn box as a right rectangular prism and the box can hold 74 cubic inches of popcorn when it

vodka [1.7K]

If the volume of the popcorn box is 74 cubic inches. Then the length of the popcorn box in inches will be 0.3 inches.

<h3>What is a rectangular prism?</h3>

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.

Gabriel models the volume of a popcorn box as a right rectangular prism and the box can hold 74 cubic inches of popcorn when it is full.

Its width is 3 and 1/2 in and its height is 77 in.

Then the width of the prism will be

$\rm W = 3 + \dfrac{1}{2}\\\\W = \dfrac{7}{2}$

Then the length of the popcorn box in inches will be

$\rm V \ = LWH\\\\\\74= L \times \dfrac{7}{2} \times 77\\\\\\L\ = 0.2745 \approx 0.3$

More about the rectangular prism link is given below.

Calculate the average rate of change for given function, from x=2 to x=7

LenaWriter [7]

"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."
