For (x, f(x)) = (5, -4), you want to find (x, -1/4·f(x)). That will be
... (5, -1/4·(-4)) = (5, 1)
Answer:
$666.25
Step-by-step explanation:
Use the equation A = P(1 + rt)
P=16.25
$650+$16.25=666.25
The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.
Set up a proportion:
3.9/11.7 = 13.2/x
Cross multiply:
3.9x = 154.44
Divide 3.9 to both sides:
x = 39.6
So the shadow for an object that is 13.2 will be 39.6 feet long.
