From the diagram you can see that we have constructed a right triangle, with height A and base 15.
Length of shadow = 15 feet.
Height of flagpole = A.
We know the angle of elevation is
40
∘
. Using this angle and the tangent ratio, we can find A.

Answer:
y = - 8 x + 2
Step-by-step explanation:
Use any two pairs to find the slope with
slope = (y2-y1)/(x2-x1)
for example: (0, 2), and (1, -6)
slope = (- 6 - 2) / (1 - 0) = - 8
so the equation should look like:
y = -8 x + b
use point (0, 2) to find b:
2 = - 8 (0) + b
b = 2
Then
y = - 8 x + 2
Answer:
2 + 2 + 2 + 2 + 2 + 2 = 4 × 3

Answer:
0.038 in decimal form.
Step-by-step explanation:
3.8% means 3.8 per 100 or simply 3.8/100.
If you divide 3.8 by 100, you'll get 0.038 (a decimal number).
As you can see, to convert from percent to decimal just divide the percent value (3.8) by 100, and remove the "%"
