Answer:
1st one is "square root of 2x"
2nd one is "2 square root of x"
3rd one is "is not"
Step-by-step explanation:
1st one: you have 2x for g(x) then you plug that into the x for f(x) giving you square root of 2x
2nd one: you have square root of x for f(x) then you plug that into the x for g(x) giving you 2 square root of x
3rd one: the inverse of the square root of x is x^2
Solution:
Let
X = height of Cody on the first day of school last year
Given:
Y= height of Cody on the first day of school year = 165 cm
10%(X)+X=Y
.10(X)+X=165
1.10X=165
X=165/1.1
<span>X=
150 cm = height of Cody on the first day of school last year</span>
The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)
<h3>What inequality represents the figure</h3>
In accordance with the figure, we have an inequation of the form y ≥ f(x). Now we proceed to find the <em>quadratic</em> equation of the parabola:
f(x) = a · (x + 1) · (x - 9)
- 125 = a · (4 + 1) · (4 - 9)
- 125 = a · 5 · (- 5)
- 125 = - 25 · a
a = - 5
f(x) = 5 · (x + 1) · (x - 9)
f(x) = 5 · (x² - 8 · x - 9)
f(x) = 5 · x² - 40 · x - 45
The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)
