Step-by-step explanation:

Given c = longest of triange = 15m

Given b = short side of triangle = 9m

By pythagoras' Theorem,

${c}^{2} = {a}^{2} + {b}^{2} \\ {a}^{2} + {b}^{2} = {c}^{2} \\ {a}^{2} + {(9)}^{2} = {(15)}^{2} \\ {a}^{2} + 81 = 225 \\ {a}^{2} = 225 - 81 \\ {a}^{2} = 144 \\ a = \sqrt{144} \\ = 12m$

Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formul

Fittoniya [83]

Answer:

The correct formula should be I= 600(0.07)(2). Juanita made a very common error, she didn't put the percentage of interest in decimal form; or she didn't put the percent sign on it so we know to put it in decimal form. Her error will make a big difference; with using her calculations the answer would be $8,400. With the correct formula the answer is $84.

If the distance covered by an object in time t is given by s(t)=t^2+5t , where s(t) is in meters and t is in seconds, what is th

alisha [4.7K]

Answer:

E. 44 meters

Step-by-step explanation:

The function that models the distance covered by the object is

$s(t)=t^2+5t$

where s(t) is in meters and t is in seconds.

The distance covered by the object after 1 second is

$s(1)=1^2+5(1)=6m$

The distance covered by the object after 1 second is

$s(1)=5^2+5(5)=50m$

The distance covered between 1 second and 5 seconds is

50-6=44m
