Answer:
<h2>The answer is 1</h2>
Step-by-step explanation:
The slope of the line between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question is points are
(8, 1) and (-1, 10)
Substitute the values into the above formula and solve for the slope
That's

We have the final answer as
<h3>1 </h3>

Answer:
h = 10sin(π15t)+35
Step-by-step explanation:
The height of the blade as a function f time can be written in the following way:
h = Asin(xt) + B, where:
B represets the initial height of the blade above the ground.
A represents the amplitud of length of the blade.
x represents the period.
The initial height is 35 ft, therefore, B = 35ft.
The amplotud of lenth of the blade is 10ft, therefore A = 10.
The period is two rotations every minute, therefore the period should be 60/4 = 15. Then x = 15π
Finally the equation that can be used to model h is:
h = 10sin(π15t)+35
Answer:
x= -9
Step-by-step explanation:
7(x+2)=-49
divide both sides by 7
(x+2)=-7
subtract 2 from both dies
x= -9
