If we take the graph with x as number of years and y as amount of dollars in it as mentioned in the equation;
gradient of the graph/ slope (m) = Change in y / change in x
so if we take a certain portion of the graph
x is the number of years, since we know the growth for one year,
lets take change in x as 1 year
y is amount of dollars, the change in amount of dollars for one year is 28
therefore change in y is 28
m(slope) = 28(change in y) / 1 (change in x)
= 28

Answer:
Vertical angle=9.5°
Time to reach maximum height = 1.24seconds
Step-by-step explanation:
The maximum distance x is reached when rope swings to a maximum height, maximum height is gotten from the equation KE= 1/2MU^2 = MgH = MgL= Mgl(1- cos theta.
Where theta is the vertical angle, U=2m/s and L= 15m
2gl -2glcostheta=U^2
2gl U^2=2gl cos theta
But theta= Acos(1- U^2)/2gl
Acos(1-/(2×9.8×15)
Theta =9.5°
Maximum height li given by
Lsintheta
But X= UxT
T=X/UX= Lsintheta/U = 15sin9.5 /2 =1.24seconds
Answer:
Hi there! The width of the rectangle is 5.5ft and the length is 8ft.
Let the width of the rectangle be represented by X. This learns us the length of the rectangle is 2X - 3.
Therefore the area of the rectangle (which is length * width) would be
Since the area of the rectangle is 44 ft^2, we end up with the following equation.
Since X represents the width (and width can't be negative), the width of the rectangle is 5.5ft
The length is
2X - 3 = 2 × 5.5 - 3 = 11 - 3 = 8ft.
