Hello from MrBillDoesMath!
Answer:
r = C/6.28
Discussion:
Note that C = 2 * Pi * r is the exact formula. As Pi is approximately 3.14, the given formula, C = 2 (3.14) r, is an approximation. Solving it for r:
C = 2(3.14) r => as 2 * 3.14 = 6.28
C = 6.28 r => divide both sides by 6.28
r ( 6.28/6.28) = C/6.28 => as 6.28/6.28 = 1
r = C/6.28
Thank you,
MrB

To solve this question, we have to find the acceleration of the car first. Acceleration refers to the rate of change of velocity of an object with respect to time.
Acceleration [A] = [V0 - V1] / T
Where VO = Initial velocity and V1 = Final velocity T represent time.
V0 = O
V1 = 18
T = 8
A = [ 0 - 18] / 8 = - 2.25
A = - 2.25 M/S^2.
To find force, we are going to use the formula: F = MA
F = ?
M = 1550
A = - 2.25
F = 1550 * - 2.25 = 3487.5
Therefore, F = -3487.5 N
The value of AOB and BOC based in the information given in the circle will be 53°.
<h3>How to calculate the values in the circle?</h3>
From the information given, the central angle is the angle that the vertex is at the center of the circle.
It was stated that OB bisects AOC. Therefore, since AOB is 53°, BOC is also 53°.
The value of AOC will now be:
= AOB + BOC
= 53° + 53°
= 106°

Answer:
Step-by-step explanation:
Equation of a line:
The equation of a line that passes through point , in point-slope form is given by:
In which m is the slope.
Finding the slope:
To find the slope of a line, we need a pair of points. The slope is given by the change in y of these points divided by the change in x.
In this question:
Points (2,2) and (4,6).
Change in y: 6 - 2 = 4
Change in x: 4 - 2 = 2
Slope:
So
I can consider any of these two points , i will use (2,2). So
