Answer:
x = 6
Step-by-step explanation:
r = 6 sec θ
r = 6 / cos θ
r cos θ = 6
x = 6
The graph is a vertical line passing through (6, 0).
<u>ANSWER</u>
<u>EXPLANATION</u>
Given 
and
We want to find
This means we substitute the function 
in to another function 
and evaluate.
This implies that;
We expand the parenthesis to obtain;
We simplify further to obtain;
Hence the correct answer is A
3 hours is 180 minutes.
She rested for 20 additional minutes, thus it will take her 200 minutes.
Explanation:
f(x) = (x-4)(x+2)
1) For x-intercept, y will be 0
<u />
<u>x-intercept</u>: (4, 0), (-2, 0)
2) For vertex: x = -b/2a where ax² + bx + c
<u>Quadratic function</u>:
<u>vertex</u>:
y: (x-4)(x+2) = (1-4)(1+2) = -9
ordered pair of vertex: (1, -9)
3) For y-intercept, x will be 0
<u>y-intercept</u>: (0, -8)
