-30x + 16. You use the distributive property to get -24x + 28 -12 -6x. Then combine like terms to get -30x + 16.

Given the function h(x), determine the functions which correctly decompose h(x) into component functions f(x) and g(x) so that h

$\large\boxed{g(x) = 7x + 2\text{ , } f(x) = \sqrt{x} - 10}$

$\text{h(x) = f(g(x)), so determine what g(x) was substituted into f(x):}\\\\\text{Given the equation } h(x) = \sqrt{7x +2}- 10:\\\\\text{In the part of the equation with a variable, we see that "7x + 2" is in a square root:}$

$\text{Therefore, we can say that g(x) = 7x + 2:}\\\\\text{If h(x) = f(7x + 2), then f(x) must be:}\\\\f(x) = \sqrt{x} - 10$

$\text{The respective functions would be:}\\\\g(x) = 7x + 2\\\\f(x) = \sqrt{x} - 10$

The angle of elevation of a cloud from a point 60m above the surface of the water of a lake is 30 and the angle of depression of

Doss [256]

Answer:

The height of the cloud is 120m

Step-by-step explanation:

From the attached diagram

BC if the height of the cloud

Given:

CD = 60 (opposite sites of ADCE are equal)

Applying Pythagoras rule to calculate AD

Tan60 = CD/AD

AD = CD X Tan60

= 60 X 1.732 = 103.92m

Using Pythagoras rule to find BD

Tan30 = BD/AD

BD = AD X Tan30

= 103.92 X 0.5773

= 59.993

BC = BD + CD

= 59.993 + 60

= 119.993

BC ~ 120m

The height of the cloud is approximately 120m
