How to solve this problem

S_A_V [24]

Step One
Solve for y
Cos(A) = adjacent / hypotenuse
Cos(A) = y / 8
y = 8 * cos(A)
y = 8 * cos(73)
y = 8 * 0.2924
y = 2.339

Step Two
Solve for x
Sin(A) = opposite / hypotenuse
Sin(73) = x / 8
x = 8 * sin(73)
x = 8 * 0.9563
x = 7.550

Check
x^2 + y^2 =? 8^2
2.339^2 + 7.55^2 =? 8^2
5.471 + 58.53 =? 64
64.000921 = 64 which is close enough.

Someone help solve 6 & 7 (will give brainliest)

riadik2000 [5.3K]

6.
$T(I(h))= \sqrt{5000( \frac{12h-h^2}{36} )}$

Since, function I stated that hours, h, pertains to the hours after 6am, and the question asks what is the temperature by 2pm, we will have h=8 because 2pm is 8 hours after 6am.

So, $T(I(h))= \sqrt{5000( \frac{12(8)-(8)^2}{36} )}

T(I(h))= \sqrt{5000( \frac{96-64}{36} )}

T(I(h))= \sqrt{5000( \frac{32}{36} )}

T(I(h))= \sqrt{ \frac{40000}{9} }

T(I(h))=66.6666 or 67$

so the answer is (3), 67.
