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
Answer:
<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u> </u></em></h2>
Step-by-step explanation:
<em><u>As</u></em>,
It has shown that line c cuts line b by making 90° so those lines are called <em><u>perpendicular bisectors </u></em><em><u>.</u></em>
<em><u>Hence</u></em>,
<em>Option B is the correct symbol shown for perpendicular bisector of line </em><em>c</em><em> </em><em>to line </em><em>b</em><em>.</em>

Answer:
$42.26
Tom spent more on tax ($1.54 vs his cousin's $0.72)
Step-by-step explanation:
Tom: $22 x 1.07 = $23.54
tax spent = 22 x 0.07 = $1.54
Cousin: $18 x 1.04 = $18.72
tax spent = 18 x 0.04 = $0.72
Total= $23.54 + $18.72 = $42.26
