Answer:
Option a) circle 5 meters and 22 meters
Step-by-step explanation:
We are given the following information in the question:
A pair of diameter and the circumference is given. We have to find a correct approximations for the diameter and circumference.
a) circle 5 meters and 22 meters
b) 19 inches and 50 inches
c) 33 centimeters and 80 centimeters
Thus, no pair gives a reasonable approximation. Only the circle with diameter 5 and circumference 22 meters have closest approximation.
Height above ground (in feet) = 10 [ 1 - 3 cos (9t degrees) ]
't' is the time, in seconds, after you sit down and the wheel starts turning.
Answer:
y-3 = -4 (x-1)
Step-by-step explanation:
y= -4x - 5
In slope-intercept form, they give us the slope, -4, and the y-intercept, -5 (we don't need for point-slope form).
Use the point (1,3) and substitute it into the equation.
Point-slope form: y-y1 = m(x-x1)
y-3 = -4 (x-1)
Answer:
b = - 14
Step-by-step explanation:
Given
- (8 + 5b) = 75 + b
Multiply through by 6 ( the LCM of 6 and 3 ) to clear the fractions
- 5(8 + 5b) = 450 + 10b ← distribute left side
- 40 - 25b = 450 + 10b ( subtract 10b from both sides )
- 40 - 35b = 450 ( add 40 to both sides )
- 35b = 490 ( divide both sides by - 35 )
b = - 14
Answer: 8x - 6
Step-by-step explanation:
Perimeter is found by doing 2l + 2w
The length is 3x - 7 and width is x + 4
2(3x - 7) + 2(x + 4) =
6x - 14 + 2x + 8 =
8x - 6
