In looking for f(g(x)), one has to substitute the expression of g(x) in place of the variable "x" in f(x). This is shown below:
Given:
f(x) = 9x - 2
g(x) = -x + 3
f(g(x)) = 9(-x + 3) - 2
f<span>(g(x)) = -9x + 27 - 2
</span>f<span>(g(x)) = -9x + 25</span>
Answer:-2
Step-by-step explanation:
slope = rise / run
y2-y1/x2-x1
(3,6) is the first set of coordinates
(5,2) is the second set of coordinates
2-6/5-3= -4/2= -2
Answer:
<h2>
The area of the sector is 40πcm²</h2>
Step-by-step explanation:
The question looks incomplete. Here is the restructured question.
"A sector with a radius of 8cm has a central angle measure of 225°. Find the area of the sector"
Formula for calculating the area of the sector is given as shown;
Area of a sector=
is the central angle and r is the radius of the circle.
Given radius = 8 cm and = 225°
On substitution, area of a sector =
The area of the sector is 40πcm²
