Answer:
i) = 23 °C
ii) = 4.4° C
Step-by-step explanation:
i) The temperature on the surface of the planet.
At the surface of the planet the height is Zero
Therefore, X = 0
Thus; using the equation, the temperature, y will be;
y = 23 - 5x
y = 23 - 5(0)
<u> = 23 °C</u>
ii) the temperature change for every kilometer from the surface,
From the equation;
y = 23 - 5x
we take, y to be 1
Therefore;
1 = 23 -5x , subtracting 23 on both sides we get
-22 = -5x
x = -22/-5
<u> = 4.4° C</u>
Answer:
Step-by-step explanation:
The only graph shown in the question doesn't have amplitude 1/2. look for a graph of a periodic wave function that has maximum y-value 1/2 (0.5) and minimum y-value 1/2 (0.5), or if it is not oscillating around the x-axis, verifies that the distance between minimum y-value and maximum y-value is "1" (one). This is because the amplitude is half of the peak-to-peak distance.
Look at the attached image as example.
The maximum value of the function y= -3+4 cos(5pi/6(x+4)) can be determined by differentiating the equation then make the derived function equal to zero. In this case, the function becomes 4 sin (5pi/6(x+4)) * (5pi/6) or equal to 10pi/3 sin (5pi/6(x+4)) = 0. sin -1 of 0 is equal to zero. hence, 5pi/6(x+4) should be zero. x is equal to -4. substituting -4 in the original equation,<span>y= -3+4 cos(5pi/6(-4+4)) is equal to 1. The maximum value is 1. </span>
