Find the inverse of f(x) = √x-1
Answer:
Step-by-step explanation:
For a function to have an inverse, it has to pass the horizontal and vertical line test, yes both of them. This function does, so we can continue. The first step for finding an inverse is replacing f(x) with y. Then switch the places of x and y.
[tex]x=\sqrt{y-1}[/tex]
Now the next step is to solve for this new y value, which is equivalent to f^-1(x). Square both sides to get rid of the radical.
[tex]x^2=y-1[/tex]
Add 1 to both sides and that is your inverse function
[tex]y=x^2+1[/tex]

Pix diameter = Circumference
A group of students stood in a circle to play a game. The circle had a diameter of 22 meters.
Which measurement is closest to the circumference of the circle in meters?
A 34.54 m
B 1,519.76 m
C 379.94 m
D 69.08 m
Answer:
69.08m
Step-by-step explanation:
Circumference of a circle = πd where
d is the diameter of the circle
Given
diameter = 22metres
circumference of the circle = 3.14(22)
circumference of the circle = 69.08m
Hence the circumference of the circle is 69.08m

What is an equation of the line that passes through the points -6, -2 and 6,-2
Answer:
y = 2
Step-by-step explanation:
m = (2 - 2)/(6 - (-6))
m = 0
there's no slope, so it's just 2
As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.
The equation will be just what I said y=2

Answer:
9) 5/10
10) 4/5
Step-by-step explanation:
A terminating decimal is a decimal that stops eventually
2/3 = 0.6666666...
5/6 = 0.833333...
5/10 = 0.5
6/9 = 0.6666666...
5/10 has a result of a terminating decimal
8/9 = 0.888888...
1/7 = 0.142857...
4/5 = 0.8
4/11 = 0.36363636....

Answer:
x=37, Angle A is 74. Exterior angle B is 185
Step-by-step explanation:
I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree
angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

Help please.
Is algebra.
Answer:
3
Step-by-step explanation:
To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).
Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).
So we have: (87-45) / (29-15)
This can be simplified to: 42/14, or 3.

is -0.75 bigger or less than -0.4?
Answer:
Because they are both negative that means they are on the left side so -0.4 is closer to the 0 so less.
Phyllis invested $13,000, a portion earning a simple interest rate of 5¼% per year and the rest earning a rate of 5% per year. After one year the total interest earned on these investments was $672.50. How much money did she invest at each rate?
Answer:
Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.
Step-by-step explanation:
Formula for the simple interest is,
Interest = [tex]\frac{P\times r\times t}{100}[/tex]
Here, P = Principal amount
r = rate of interest
t = Duration of investment
Let Phyllis invested amount (at 5.25% rate of interest) = $x
Therefore, Interest on this amount,
Interest = [tex]\frac{5.25\times x}{100}[/tex]
= $0.0525x
If he invested the rest amount $(13000 - x) at the rate of 5%,
Interest earned on this amount = [tex]\frac{(13000-x)\times 5\times 1}{100}[/tex]
= $(650 - 0.05x)
Interest earned on total amount = $672
Therefore, $0.0525x + $(650 - 0.05x) = $672.5
0.0025x + 650 = 672.5
0.0025x = 22.5
x = $9000
Rest amount = 13000 - 9000
= $4000
Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Actually Welcome to the Concept of the Surface areas and Volume.
Since Box A is cube, it's volume is Side^3
hence taking the cube root of 512 , we get as,
Side length of Box A is 8 m.
hence diving 8/2 = 4 m
4 m is a side of Box B.
hence, Volume of Box B is = (4)^3 = 64 cubic metres.
Vol. Box B = 64 m^3
Answer:
The correct answer is D: 64 meters cubed
Step-by-step explanation:
You can take any example but let's say 128 times 2 times 2 which equals box A, now you must divide all dimensions by 2 and you will get 64 times 1 times 1 which adds up to 64, this will work with any example.
