Answer:
y=1x+11
Step-by-step explanation:
1. Find the slope of the given points
2. Pick any point to find the y-intercept
(3, 14)
x=3, y=14, m=1
3. Substitute
y=mx+b
14=1(3)+b
14=3+b
14-3=b
11=b
4. Write the linear function rule
y=mx+b
y=1x+11
I'm not sure if this is correct but you would put it into an equation while you solve for X. so 0.75x=150 or equivalently would be like (3/4)x=150 Then after that you would divide both sides by 0.75 or 3/4
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:
8.22in
Step-by-step explanation:
Area of circle = πr²
r is the radius
Given
Area = 212in²
Substitute
212 = πr²
r² = 212/3.14
r² = 67.52
r = √67.52
r = 8.22in
hence the radius of the circle is 8.22in
