Which function is the inverse of function f?
f(x)=9x^2–12
Answers
Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D

PLEASE HELPP!!! And show the work/explain please. Picture is above :)
Answers
Answer:
x = -24/7
Step-by-step explanation:
To solve, you need to multiply both sides by 10 ( the GCF of 5 and 2) to get rid of the fractions. Once multiplied, you get this:
2(4x-2) + 5(1) = 5(3x+7) - 10(1)
Now, just distribute the parenthesis:
8x - 4 + 5 = 15x + 35 - 10
Now, combine like terms:
8x + 1 = 15x + 25
15x + 25 = 8x + 1 (rearranged the equation)
Subtract the x's:
7x + 25 = 1
Now solve:
7x = -24
x = -24/7

Whole numbers have no decimals or fractions. The area is found by multiplying the base times the height.
a cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.
enter the height, in feet, of the cylinder in decimal from. round your answer to the nearest tenth.
Answers
Answer:
Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:
[tex]R = \dfrac{D}{2}[/tex]
So, radius, R = [tex]\frac{6}{2} \Rightarrow 3[/tex] feet
Let height of cylinder be [tex]h[/tex] feet.
Formula for volume of cylinder is given by:
[tex]V = \pi R^{2} H[/tex]
Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,
[tex]V = \dfrac{36 \pi}{5} ft^{3}[/tex]
Using formula for volume, [tex]V = \pi R^{2} H[/tex]
[tex]\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft[/tex]
Hence, Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].

Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this: [tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex](the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form: [tex]ax^{2} +bx+c=0[/tex])
So, we just have to input the stuff from our equation into the formula!
[tex]x=\frac{-4+-\sqrt{32} }{2}[/tex]
Now, we can simplify the square root of 32 into 4 times the square root of 2
[tex]x=\frac{-4+-4\sqrt{2} }{2}[/tex]
And, we can divide 2 from it all!
[tex]x=-2+-2\sqrt{2}[/tex]
So, there you have it! The Answer is C, or 3.
Hope this helps!

Answer:
Step-by-step explanation:
A) Cost of canvas = $ x
Cost of 4 canvases = 4 *x = 4x
Money left over after buying 4 canvases = $2.20
Equation: 25 - 4x = 2.2
Solution: Subtract 25 from both sides
-4x = 2.2 - 25
-4x = - 22.8
Divide both sides by (-4)
-4x/-4 = -22.8/-4
x = 5.7
B) Money in Molly's account= x
4 times of Molly's account = 4x
Equation: 4x - 2.2 = 25
Solution: 4x = 25 +2.2
4x = 27.2
x = 27.2/4
x = 6.8

Which is a possible turning point for the continuous
function f(x)?
O (-2,0)
O (0, -2)
O (2-1)
O (4,0)
Answers
Answer:
(0, -2)
Step-by-step explanation:
A turning point is a point at which the derivative changes sign from positive to negative or vice versa. Then, a turning point coincides with a relative maximum or a relative minimum (also known as local minimum and maximum).
From the table, we see that f(x) decreases from x = -6 to x = 0 and it increases from x = 0 to x = 6. Therefore, there is a minimum at (0, -2)

What is the slope of the line that is represented by the values in the table above?
Answers
Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope, [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To calculate the slope we only require two pair of points.
Let us take: [tex](x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)[/tex]
[tex]m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5[/tex]
The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.

y y=-7x+3
y=-x-3
Answers
Answer:
The equation of the line in slope-intercept form is:
[tex]y=-\frac{3}{7} x+3\\[/tex]
In one of the many possible standard forms:
[tex]3\,x+7\,y=21[/tex]
Step-by-step explanation:
First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):
[tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{0-3}{7-0}=-\frac{3}{7}[/tex]
Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:
[tex]y=m\,x+b\\y=-\frac{3}{7} x+3[/tex]
And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":
[tex]y=-\frac{3}{7} x+3\\7\,y=-3\,x+21\\3\,x+7\,y=21[/tex]

[tex]V \approx 3053.63[/tex] [tex]cm^3[/tex] (Rounded to the nearest hundredth if needed)
Step-by-step explanation:
-To find the volume of sphere, you need this formula to help you solve the problem:
[tex]V = \frac{4}{3} \pi r^3[/tex]
-Use the given radius [tex]9[/tex] for the formula:
[tex]V = \frac{4}{3} \pi 9^3[/tex]
-Then, you solve:
[tex]V = \frac{4}{3}\pi \times 9^3[/tex]
[tex]V = \frac{4}{3} \pi \times 729[/tex]
[tex]V = \frac{4 \times 729}{3} \pi[/tex]
[tex]V = \frac{2916}{3} \pi[/tex]
[tex]V = 972\pi \approx 3053.628[/tex] [tex]cm^3[/tex]
