Answer: Choice C
Domain: x < -2
Range: y > 1
=================================
Explanation:
When going from the original function [tex]f(x)[/tex] to its corresponding inverse [tex]f^{-1}(x)[/tex], or vice versa, the roles of x and y swap places. The inverse undoes whatever the original function does.
This swap means that the domain and range also swap as well. The original domain x > 1 becomes the range y > 1 for the inverse. The range y < -2 in the original becomes x < -2 which is the domain of the inverse.
The domain and range of the inverse functions are:
domain: x < - 2range: y > 1.What are the domain and range of the inverse function?We know that two functions are inverses if:
f( g(x)) = x
g( f(x)) = x
So, the domain of f(x) is the range of g(x), and the range of f(x) is the domain of g(x).
Then the domain and range of the inverse function are:
domain: x < - 2range: y > 1.If you want to learn more about domain and range:

In AHIJ, the measure of ZJ=90°, the measure of ZI=62°, and IJ = 57 feet. Find the
length of JH to the nearest tenth of a foot.
Answer:
[tex]x = 107.2[/tex]
Step-by-step explanation:
[tex]57 = ih \cos(62) \\ ih = \frac{57}{ \cos(62) } \\ \\ x = ih \sin(62) \\ x = \frac{57}{ \cos(62) } \times \sin(62) \\ x = 107.2[/tex]
Answer:
Step-by-step explanation:
The graph had prove the adjacent length of angle ZI, which is 57. And asks the opposite side of angle ZI, we use tan. to solve for x.
tan (62) = opposite side / adjacent side
tan (62) = x / 57
tan (62) x 57 = x
x = 107.2

3(a - 4) + 1 = 9 - a
O a = 3
a = 5
O a = 6
O a = 10
Answer:
B. a = 5
Step-by-step explanation:
3(a - 4) + 1 = 9 - a
Distribute the 3 into the parenthesis.
3a - 12 + 1 = 9 - a
Add -12 and 1.
3a - 11 = 9 - a
Add a to both sides.
4a - 11 = 9
Add 11 to both sides.
4a = 20
Divide both sides by 4.
a = 5.
Proof:
3(a - 4) + 1 = 9 - a
Substitute variable.
3(5 - 4) + 1 = 9 - 5
Subtract inside parenthesis.
3(1) + 1 = 9 - 5
Multiply 3 and 1.
3 + 1 = 9 - 5
Add 3 and 1.
4 = 9 - 5
Subtract 5 from 9.
4 = 4.

[tex]\\ \sf\longmapsto Area=3.14(25)[/tex]
[tex]\\ \sf\longmapsto Area=78.5cm^2[/tex]
Answer:
1. Diameter of a semicircles =14cm
Radius or semicircle =7cm
*Area if circle =pi radius 2
=22/7 × 7×7cm 2
=154cm 2
But semicircle is half if a circle so,
Area of a semicircle =1/2 ×154cm2
=77cm2
2. Radius of the circle =1cm
Area of the circle=pi radius 2
=3.14×1×1
=3.14cm2
3.Diameter of a circular lawn=10m
Radius of the circular lawn =5m
Area of the circular lawn =pi radius2
=3.14×5m×5m
=78.5m2

You invest $10,000 into two accounts. One account earns 5% annually and the other earns 8% annually. If the total interest earned from both accounts in a year is $590, how much is invested in each account?
Answer:
$7,000 in the 5% account
$3,000 in the 8% account
Step-by-step explanation:
Let x be the amount invested at 5% the remainer is at 8%
.05x + .08(10000 - x) = 590
Distribute
.05x + 800 - .08x = 590
Combine like terms
-.03x = -210
Divide both sides by-.03
x = 7000 in the 5% account
1000 - x = 3000 in the 8% account
Put these in order starting with the smallest.

Answer:
1/2
Step-by-step explanation:
A quadratic equations that has solutions p and q can be factored as ...
(x -p)(x -q) = 0
When this is expanded, it becomes ...
x^2 -(p+q)x +pq = 0
That is, the opposite of the x-coefficient is the sum of the solutions.
__
We can put your quadratic into this form by dividing by the leading coefficient, 4.
(1/4)(4m^2 -2m -6) = 0
m^2 -1/2m -3/2 = 0
The coefficient of the linear term is -1/2. This tells us the sum of the solutions is -(-1/2) = 1/2.
is the product of two irrational numbers always gonna be irrational
well, we can say that √2 and √7 are irrational numbers, they do not provide a value that can be written in a "ration" or fractional.
we can also say that √2 * √7 is √(14), which is also irrational.
However, how about √7 * √7, that's √7² or namely just 7, and that's a rational, so nope, not always.
Which of these is a ratio equivalent to 3/2?
A. 6/4
B. 3/4
C. 5/2
D. 5/2

Step-by-step explanation:
________|45 ÷ 15=3|__________________________|5/6 AND 3/4: 5 + 3= 8, 6 + 4= 10|If Parin digs a hole at a rate of 5/6 feet every 15 minutes. After digging for 45 minutes, Parin places a bush in the hole that fills exactly 3/4 feet of the hole. Then the elevation of the hole after placing the bush in the hole is [tex]1\frac{3}{4}[/tex]
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Parin digs a hole at a rate of 5/6 feet every 15 minutes.
In 45 minutes, Parin digs a hole of 5/6×45/15
5/6×3
5/2
The total depth of the digging = 5/2
Now, 3/4 feet dig is filled by bush, so the remaining elevation of the depth, = 5/2- 3/4
five by two minus three by four.
5/2-3/4
Take LCM of 2 and 4
(10-3)/4
7/4
the elevation of the hole after placing the bush in the hole is 7/4.
Now we can write in mixed fraction [tex]1\frac{3}{4}[/tex]
Hence elevation of the hole after placing the bush in the hole is [tex]1\frac{3}{4}[/tex]

Answer:
x can equal any number between 0 and 8. This also includes 8.
Step-by-step explanation:
As noted in the problem, x is more than -1 (x > -1)
So we can infer that -1 and anything past it to the left is not a viable answer.
As noted in the problem, x is lesser than or equal to 8 (x ≤ 8) meaning that anything past 8 to the right will not be a viable answer.///

The centroid of a triangle divides the triangle in 1/3 and 2/3.
The length of NM is 6 units
The given parameters are:
IM = 18
KN = 4
HL = 15
The centroid of the triangle divides line IM to NM and NI, where NM < NI
So, we have:
[tex]\mathbf{NM = \frac 13 \times IM}[/tex]
This gives
[tex]\mathbf{NM = \frac 13 \times 18}[/tex]
