Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun
Answer:
h(x) = - 4x² + 5
Step-by-step explanation:
To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)
h(x) = - 2(2x² + 1) + 7
= - 4x² - 2 + 7
= - 4x² + 5
3. X= y-3
You subtract 3 to the other side to make X the subject of the formula.
