Answer:
a. $3.36
b. $70.86
Step-by-step explanation:
5% of $67.50 is $3.36
$67.50 + $3.36 = $70.86
Answer:
2(d-vt)=-at^2
a=2(d-vt)/t^2
at^2=2(d-vt)
Step-by-step explanation:
Arrange the equations in the correct sequence to rewrite the formula for displacement, d = vt—1/2at^2 to find a. In the formula, d is
displacement, v is final velocity, a is acceleration, and t is time.
Given the formula for calculating the displacement of a body as shown below;
d=vt - 1/2at^2
Where,
d = displacement
v = final velocity
a = acceleration
t = time
To make acceleration(a), the subject of the formula
Subtract vt from both sides of the equation
d=vt - 1/2at^2
d - vt=vt - vt - 1/2at^2
d - vt= -1/2at^2
2(d - vt) = -at^2
Divide both sides by t^2
2(d - vt) / t^2 = -at^2 / t^2
2(d - vt) / t^2 = -a
a= -2(d - vt) / t^2
a=2(vt - d) / t^2
2(vt-d)=at^2
Answer:
-3 + sqrt 42
-3 - sqrt42
Step-by-step explanation:
assuming you want me to factor it and then find the roots:
2x^2 +12x-66
2(x^2 + 6x-33)
The two numbers that adds up to 23 and mutliplies to 26 are 1.19 and 21.808.
21.808 + 1.19 ≈ 23
21.808 × 1.19 ≈ 26
Answer:
40
Step-by-step explanation:
There are 98 fliers in total
she posted 2/7 in the first week which is equal to : 98 ÷ 7 × 2 = 28
In second week she posted 3/7 of the remaining fliers which is equal to : 70 ÷ 7 × 3 = 30
She has 40 fliers left that is not posted yet.
