Answer:
True
Step-by-step explanation:
The formula for an area of a circle is a = pi times radius squared
Answer:
x = 14
Step-by-step explanation:
∠ DCA and ∠ BCF are adjacent angles and sum to 180° , then
∠ DCA = 180° - 124° = 56°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
6x is an exterior angle , then
6x = 2x + 56 ( subtract 2x from both sides )
4x = 56 ( divide both sides by 4 )
x = 14
Answer:
Left side of graph of function would be up .
Step-by-step explanation:
Given : 
.
To find : In which direction does the left side of the graph of this function point.
Solution : We have given that .
We can see from the given function Degree is even and leading coefficient is positive .
By the behavior of end points : left side of graph would be up .
Therefore, left side of graph of function would be up .
Answer:
f⁻¹(x) = x/4 + 1/2
Step-by-step explanation:
To find the inverse of a function, switch the x and y variables, then isolate y.
f(x) replaced y, so you can replace it back.
y = 4x - 2
x = 4y - 2 Switched x and y
x + 2 = 4y Added 2 to both sides
y = x/4 + 2/4 Divided both sides by 4
y = x/4 + 1/2 Simplified
f⁻¹(x) = x/4 + 1/2 Use function notation
