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]
how to I do Ratios with cross multiplying
Answer:
To cross multiply, multiply the numerator from one side with the denominator of the other side and put that product on one side of the equation. Do the same with the other numerator/denominator and put that on the other side. From there, solve for the unknown part.
So your ratio might look like this:
4/6=x/12
6x=12(4)
6x=48
x=8
So in this case 4/6 would equal 8/12.

Answer:
angle 1 and angle 2 are supplementary angles
Step-by-step explanation:
When the base of the angles forms a straight line, the sum of the angles is 180°. That's the definition of supplementary angles.
Complementary angles form a right angle. The sum of complementary angles is 90°
A slightly silly way to remember Complementary angles: The two angles look at each other and compliment each other saying, "You look all right to me!"
"Yes, we are so right together!"
:)
Write the ratio as a fraction in simplest form write the whole number in the numerator and denominator 24:56

Solve: 4 - 2 x 8 + (6 x 2) x 4 + 3^2
Answer:
42
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
4 - 2 × 8 + (6 × 2) × 4 + 3²
= 4 - (2 × 8) + (6 × 2) × 4 + 3²
= 4 - 16 + 12 × 4 + 9
= (4 - 16) + (12 × 4) + 9
= -12 + 48 + 9
= 45

A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length 2 feet. The height, h, of the sand in the container increases at a rate of approximately 8 inches per minute. Create an equation that models the volume, V, of the sand in the container in terms of h, then use the equation to determine the time at which the volume is 64 cubic feet. Note that the volume of a rectangular prism is V=l×w×h, where l, w, and h are the length, width, and height of the prism.

12. A line contains of at LEAST two points.
13. A plane contains at least three non-collinear points.
14. Two lines intersect at a point.
15. Two planes intersect at a point.
16. A line and a plane intersect at a line.
Answer:11 is false. Through any two points there is exactly one line. 12 is true. 13 is true. 14 is true. 15 is false. Two planes intersect at a line. 16 is false. A line and a plane would intersect at a point

w-7=-4 i do not no this one please help me
Answer: i believe what you're looking for is W so, W=3
Step-by-step explanation: you add +7 to each side of the equation, which gives you W=3
Answer:
w= 3
Step-by-step explanation:
Add 7 to both sides of the equation w-7 = -4
w-7+7=-4+7
Simplify : w-7+7=-4+7 which simplifies to w= -4 +7
So, w = -4 +7 is w= 3

A train is traveling at a constant speed and goes 17 kilometers in 8 minutes. How far will the train travel in 60 minutes.
Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
Distance B = 1275 km
