The functions are illustrations of composite functions.
<em>The soil temperature at 2:00pm is 67</em>
The given parameters are:
---- the function for sun intensity
-- the function for temperature
At 2:00pm, the value of h (number of hours) is:
![\mathbf{h = 2:00pm - 6:00am}](https://tex.z-dn.net/?f=%5Cmathbf%7Bh%20%3D%202%3A00pm%20-%206%3A00am%7D)
![\mathbf{h = 8}](https://tex.z-dn.net/?f=%5Cmathbf%7Bh%20%3D%208%7D)
Substitute 8 for h in
, to calculate the sun intensity
![\mathbf{I(8) =\frac{12 \times 8 - 8^2}{36}}](https://tex.z-dn.net/?f=%5Cmathbf%7BI%288%29%20%3D%5Cfrac%7B12%20%5Ctimes%208%20-%208%5E2%7D%7B36%7D%7D)
![\mathbf{I(8) =\frac{32}{36}}](https://tex.z-dn.net/?f=%5Cmathbf%7BI%288%29%20%3D%5Cfrac%7B32%7D%7B36%7D%7D)
![\mathbf{I(8) =\frac{8}{9}}](https://tex.z-dn.net/?f=%5Cmathbf%7BI%288%29%20%3D%5Cfrac%7B8%7D%7B9%7D%7D)
Substitute 8/9 for I in
, to calculate the temperature of the soil
![\mathbf{T(8/9) =\sqrt{5000 \times 8/9}}](https://tex.z-dn.net/?f=%5Cmathbf%7BT%288%2F9%29%20%3D%5Csqrt%7B5000%20%5Ctimes%208%2F9%7D%7D)
![\mathbf{T(8/9) =\sqrt{4444.44}}](https://tex.z-dn.net/?f=%5Cmathbf%7BT%288%2F9%29%20%3D%5Csqrt%7B4444.44%7D%7D)
![\mathbf{T(8/9) =66.67}](https://tex.z-dn.net/?f=%5Cmathbf%7BT%288%2F9%29%20%3D66.67%7D)
Approximate
![\mathbf{T(8/9) =67}](https://tex.z-dn.net/?f=%5Cmathbf%7BT%288%2F9%29%20%3D67%7D)
Hence, the soil temperature at 2:00pm is 67

1/2
Is the answer
To the problem
Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x
Step-by-step explanation:
Answer:
The zeroes are -1, 3, and -2
The y intercept is located at (0,6)
Step-by-step explanation:
(x+2)=0
x=-2
The easiest way is to use an online graph like desmos and graph the problem there. You can see where the y intercept is.
NO. Sine is opposite/hypotenuse, so the answer should be 24/25
