Answer:A. Yes, they are inverse of each other.
B. Domain and range of the compositions is .
Step-by-step explanation:
A. We have, and .
Now, 'when two functions f and g are inverses of each other, they satisfy the property '.
So, we have,
Thus, we get for the given function f and g, .
Hence, they are inverse of each other.
B. Now, as we have,
That is, the composition of the functions is equal to the identity function.
Thus, the domain and range are the set of all real numbers respectively.
So, in the interval notation, we have,
Domain and range of the compositions is .

help me please don't understand (see picture)
Answer:
< F would be 140 degrees
Step-by-step explanation:
So what you would do is that since they told you angle D is 40 degrees and you know that the 2 lines in there are parallel, and since they are asking for angle F, whne you add angle F and angle H they should equal 180 degrees which you know so you just subtract 40 degrees from 180 and you get 140 degrees which if angle F and you can subtract 40 since angle H and angle D would be congruent.

Arnie is mixing red and yellow paints to make two different shades of orange. To make 1 cup of dark orange paint, he needs 7 ounces of red paint and 1 ounce of yellow paint. To make 2 cups of light orange paint, he needs 13 ounces of yellow paint and 3 ounces of red paint. Answer parts a and b.
Answer:
Arnie has enough red paint
Step-by-step explanation:
step 1
Find out the number of ounces of red paint needed to make 3 cups of dark orange paint
Let
x -----> number of ounces of red paint
y -----> number of ounces of yellow paint
z ----> cups of dark orange
we know that
\frac{x}{z}=\frac{7}{1}\ \frac{ounces\ red\ paint}{cups\ dark\ orange}
z
x
=
1
7
cups dark orange
ounces red paint
so
For z=3 cups
substitute and solve for x
\frac{x}{3}=\frac{7}{1}
3
x
=
1
7
x=21\ ounces\ of\ red\ paintx=21 ounces of red paint
step 2
Find out the number of ounces of red paint needed to make 3 cups of light orange paint
Let
x -----> number of ounces of red paint
y -----> number of ounces of yellow paint
z ----> cups of light orange
we know that
\frac{x}{z}=\frac{3}{2}\ \frac{ounces\ red\ paint}{cups\ light\ orange}
z
x
=
2
3
cups light orange
ounces red paint
so
For z=3 cups
substitute and solve for x
\frac{x}{3}=\frac{3}{2}
3
x
=
2
3
x=4.5\ ounces\ of\ red\ paintx=4.5 ounces of red paint
step 3
Adds the ounces of red paint
21+4.5=25.5\ ounces\ of\ red\ paint21+4.5=25.5 ounces of red paint
25.5\ ounces < 32\ ounces25.5 ounces<32 ounces
therefore
Arnie has enough red paint

Answer:
c) [tex]h(t)=-16(t-1.5)^{2}+676[/tex]
Step-by-step explanation:
Each of the given equations is written in vertex form. This means that the vertex is written in the equation. The quadratic term (the term to the second degree), contains (x), and a value that is either added or subtracted to it. The additive inverse (meaning a number times negative one) of that number is the x-coordinate of the vertex. Therefore, the term inside the parenthesis is (-1.5). The constant is the y-coordinate of the vertex, and therefore it is 676. Since the object is being thrown off a cliff, gravity acts on it. The gravitational constant in feet per second is (-16), hence the coefficient of the quadratic term is (-16).

Aylin went to the store to buy some new folders for school . She bought a total of 7 folders and spent a total of $12. She bought two different types of folders. Plain folders that cost $1 each and folders with cartoons that cost $2 each. How many did each type of folder did Aylin buy?
Answer:
2 plain folders and 7 folders with cartoons
Step-by-step explanation:
Given data
Let the number of plain folders be x
and the number of folders with cartoons be y
x+y=7------------1
x+2y=12----------2
from 1
x= 7-y
put this in 2
7-y+2y=12
7+y= 12
y= 12-7
y=5
Put y=5 in 1
x+5= 7
x= 7-5
x= 2
Hence Ayin bought 2 plain folders and 7 folders with cartoons

What is the slope of the line?
Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.
Step-by-step explanation:
Answer:
slope = [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]
