Answer:
s = 22.5 m
Step-by-step explanation:
the equation for the speed change of a coach moving along a straight section of the road and starting braking at a speed of 20 m / s has the form v (t) = 25-5t. Using integral calculus, determine the coach's braking distance.
v (t) = 25 - 5 t
at t = 0 , v = 20 m/s
Let the distance is s.

Let at t = t, the v = 20
So,
20 = 25 - 5 t
t = 1 s
So, s = 25 x 1 - 2.5 x 1 = 22.5 m
Solution:
use the trigonometric function which is tangent
tangent is equal to opposite/hypotenuse
the angle is 11 degrees
28 foot will be your opposite
your hypotenuse is the missing
tan(11 degrees)=28 foot/ hypotenuse
hypotenuse= [28 foot/ (tan 11 degrees)]
hypotenuse = 98.8 feet
Answer:
The x-intercept is 5.
Some people prefer you right it as a point (5,0).
Step-by-step explanation:
The x-intercept can be found by setting y=0 and solving for x.
Just like to find the y-intercept you can set x=0 and solve for y.
Let's find the x-intercept.
So we will set y=0 and solve for x:
3x-9y=15
3x-9(0)=15
3x-0 =15
3x =15
Divide both sides by 3:
x =15/3
x =5
So the x-intercept is (5,0).
