Answer:
161
Step-by-step explanation:
Given the functions
f (x) = 2x^2 – 1
g(x) = 3x
we are to find f(g(3))
First look for the composite function f(g(x))
f(g(x)) = f(3x)
f(3x) = 2(3x)² - 1
f(3x) = 2*9x² - 1
f(3x) = 18x² - 1
f(g(x)) = 18x² - 1
Substitute x = 3 into the result
f(g(3)) = 18(3)² - 1
f(g(3)) = 18*9- 1
f(g(3)) = 162-1
f(g(3)) = 161
Hence f(g(3)) is 161
Answer:
<h2>Q1. x = 17.1; y = 5.6</h2><h2>Q2. x = 9.7; y = 24.1</h2>
Step-by-step explanation:
Use sine and cosine.


Q8.
We have:

Substitute:
<em> multiply both sides by 18</em>

<em>multiply both sides by 0.9511</em>

Q9.
We have:

Substitute:
<em>multiply both sides by 26</em>

<em>multiply both sides by 26</em>

Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
<h3>Lines and angle</h3>
A line is the shortest distance between two points where. the points where two lines meet is an angle.
There are several types of angles including acute, obtuse, right and straight
For acute angle, the angle is less than 90 degrees
For obtuse, the angle is greater than 90 and less than 180 degrees
For right angle, the angle is 90 degrees
Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
