Answer:
h=7.5 in
Step-by-step explanation:
see the attached figure with letters to better understand the problem
In the right triangle ABC
sin(CAB)=15/18 ----> opposite side divided by the hypotenuse
In the right triangle CDE
sin(DCE)=h/9 ----> opposite side divided by the hypotenuse
In this problem
∠CAB=∠DCE ------> by corresponding angles
therefore
sin(CAB)=sin(DCE)
15/18=h/9
solve for h
h=15*9/18
h=7.5 in
Answer:
Step-by-step explanation:
The function seems to increase at a constant rate of 3 units. This means that the equation that satisfies these points could be that of a straight line.
We use the first two points to find the slope of the line.
(0, -10)
(1, -7)
(2, -4)
The equation of a line is:
Where m is the slope of the line and b is the cutoff point with the y axis.
To find the slope of a line we use the following equation:
So:
The cut point (b) is found by replacing in the previous equation, any of the three points provided and clearing b.
Now we can write the equation of the line sought.
You can verify that the three points provided belong to this equation.
