Select the correct function. Select the function with an average rate of change of 3 over the interval [1, 3].
Answers
Answer:
Function g(x)
Step-by-step explanation:
Given
See attachment for functions
Required
Which has an average rate of 3 over [1,3]
The average rate of change (m) is calculated as:
[tex]m = \frac{f(b) - f(a)}{b -a}[/tex]
Where:
[tex][a,b] = [1,3][/tex]
So, we have:
[tex]m = \frac{f(3) - f(1)}{3 -1}[/tex]
[tex]m = \frac{f(3) - f(1)}{2}[/tex]
From the table f(x), we have:
[tex]f(3) = 6\\ f(1) = -2[/tex]
So:
[tex]m = \frac{6 - -2}{2}[/tex]
[tex]m = \frac{8}{2}[/tex]
[tex]m =4[/tex]
From the graph of g(x), we have:
[tex]g(3) = 4\\ g(1) = -2[/tex]
So:
[tex]m = \frac{g(3) - g(1)}{2}[/tex]
[tex]m = \frac{4 - -2}{2}[/tex]
[tex]m = \frac{6}{2}[/tex]
[tex]m =3[/tex]
Since only one of the function has an average rate of change of 3 over the given interval,
Then g(x) answers the question

Answers
Step-by-step explanation:
5x²-45=05x²=45x²=9x=√9x=3hope it helps.
Answer:
x=±√9 or x= 3, x=-3
Step-by-step explanation:
The problem requires us to find the x.
So we must isolate the variable, as so-
[tex]5x^2-45=0\\5x^2=45[/tex] (add 45 to both sides)
Now we can divide both sides by -
[tex]5x^2=45\\x^2=9[/tex]
Now we must square root both sides to find the root of x.
[tex]\sqrt{x^2} =\sqrt{9}[/tex]
x=±√9
or x= 3, x=-3

Alexandra paid $7dollar to park her car for 3hours at the parking garage. The garage charges a constant hourly parking rate. Write an equation that shows the relationship between p, the number of hours parked, and c, the cost in dollars.
Let the constant = k
The relationship is written as:
c = p×h + k
P = cost of parking
h = Number of hours parked
c = $7 × 3 + k
c = 21 + k

The length of a swing is 2.1m if the length of the arch that is made by the swing is 4.4m calculate the angle swept by the swing
Answers
Answer:
The angle swept by the swing is 120 degrees
Step-by-step explanation:
Here, we are given the radius of the circle that makes the arc, and the length of the arc
Mathematically, we are to find the central angle
That would be;
The length of an arc is;
theta/360 * 2 * pi * r
theta is the central angle we are looking for and r in this case is 2.1 m
Thus, we have it that;
theta/360 * 2 * 22/7 * 2.1 = 4.4
theta = (360 * 4.4 * 7)/(2 * 22 * 2.1)
theta = 120 degrees

[tex]38+7·(x-3)=9·(x+1)[/tex]
Answers
[tex]38 + 7x - 21 = 9x + 9[/tex]
Combine like terms.
[tex]17 + 7x = 9x + 9[/tex]
Eliminate a x.
[tex]17 = 2x + 9[/tex]
[tex]8 = 2x[/tex]
[tex]x = 4[/tex]
38 + 7x - 21 = 9x + 9
7x + 17 = 9x + 9
Subtract both sides 9
7x + 17 - 9 = 9x + 9 - 9
7x + 8 = 9x
Subtract sides 7x
7x - 7x + 8 = 9x - 7x
8 = 2x
Divide both sides by 2
8 ÷ 2 = 2x ÷ 2
x = 4
