Function f(4) = -10 and if g(x) = 2 , x = 0.
To find f(4), we will observe the graph of f(x).
According to the graph of f(x),
when x = 4, y is -10 which means when x is 4 value of f(4) is -10.
To find the value of x when g(x) is 2, we will observe the graph of g(x).
According to the graph of g(x),
when y = 2, x is 0 which means that when x is 0, the value of g(x) is 2.
Hence, f(4) is -10 and x = 0 when g(x) = 2.

Answer:

Step-by-step explanation:
The reference angle is an acute angle that angle in standard position makes with the positive x-axis.
The given angle in radians is

This angle is already acute and hence it is itself a reference angle.
The reference angle of any angle in the first quadrant is the same angle.
Answer:
Exfoliation
Step-by-step explanation:
Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.
49 pieces because 7/8 is equivalent to 49/56. If each piece is 1/56, then there 49 of them.
Answer:
The third one
Step-by-step explanation:
Its because we need to find the number that it has grown.
so we add the number that it grew to the size it was before.
