find (g•f)(3) f(x)=3x-2 g(x)=x^2
Answer:
f(x)=3x-2
g(x)=x^2
(g o f)(3)=?
(g o f)(3)=g(f(3))
x=3→f(3)=3(3)-2
f(3)=9-2
f(3)=7
(g o f)(3)=g(f(3))=g(7)
x=7→g(7)=7^2
g(7)=49
Answer: (g o f)(3)=49
OR,if you like this answer can also work
For this case, the first thing we must do is the composition of functions.
We have:
f (x) = 3x-2
g (x) = x ^ 2
(gOf) (x) = (3x-2) ^ 2
We now evaluate the function:
(gOf) (3) = (3 * (3) -2) ^ 2
(gOf) (3) = (9-2) ^ 2
(gOf) (3) = (7) ^ 2
(gOf) (3) = 49
Answer:
(gOf) (3) = 49
Both are same

3 feet is how many meters? Hint: 1 ft = 0.305 m Round your answer to the nearest tenth.
Answer:
3 feet = 0.9 meters.
Step-by-step explanation:
If one foot equals 0.305 meters and you need to find how many meters three feet would be, you need to multiply 3 and 0.305. The answer is 0.915, and after rounding that to the nearest tenth, you get 0.9.

what is the measure of
a) 30 degrees
b) 40 degrees
c) 70 degrees
d) 110 degrees
Answer:
70
Step-by-step explanation:
The sum of the angles of a triangle should always add up to 180 degrees.
In this problem, they have given us 2 angle measures of the triangle - 40 degrees and 70 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.
I'm just going to do some simple math:
40 + 70 = 110 (sum of the 2 angles)
180 - 110 = 70 (subtracting 180 by the sum of the 2 angles)

What is the slope of a line perpendicular to the line whose equation is 12x-9y=135
Answer:
[tex]\frac{-9}{12}[/tex]
Step-by-step explanation:
First, we need to isolate y.
1. Subtract 12x from both sides.
-9y=-12x+135
2. Divide by -9 in order to isolate y.
[tex]y=\frac{12}{9} x-15[/tex]
3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].
The mean of 8 and another number is 13. what is the other number?
Work Shown:
x = the unknown number
The mean of 8 and the unknown number is 13. This indicates we add up 8 and x, then divide by 2, and we'll get 13.
(8+x)/2 = 13
8+x = 2*13 .... multiply both sides by 2
8+x = 26
x = 26-8 .... subtract 8 from both sides
x = 18
As a check,
(8+18)/2 = 26/2 = 13
This shows the mean of {8,18} is 13.
The second number is 18.
Given to us,
First number, [tex]N_f = 8[/tex],
Mean of two numbers, [tex]m = 13[/tex]
Let us assume second number as x,
Also, we know mean is the arithmetic average of given numbers.
[tex]Mean =\dfrac{Sum\ of\ all\ the\ data\ given}{Numbere\ of\ data\ given}[/tex]
[tex]m=\dfrac{8+x}{2}\\\\13=\dfrac{8+x}{2}\\\\13\times 2 = 8+x\\8+x=26\\x=26-8\\x=18[/tex]
Hence, the second number is 18.

what is there value of y?
what is the value of x?
Answer:
x=14
y=30
Step-by-step explanation:
5x+25=3x+53
5x=3x+28
2x=28
x=14
2y+35=95
2y=60
y=30
(I assumed all of the angles are equal, correct me if I'm wrong.)
Answer:x=14
Step-by-step explanation:
Let's first understand what we need to do. We need to solve for two variables, x and y. We do these by setting two systems of equations equal to each other. This is easily done for x, but for y the other equation is missing. Keep this in mind for later.
So, we will first start off by solving for x. We do this by using inverse operations.
5x+25=3x+53 We will subtract
5x=3x+28
2x=28 Divide
x=14
You can plug 14 into both the xs and they will be similar, and both will have the similar results once you solve for y and plug it into the equation along with x.
We know that the 5x+25 on the left is adjacent to 2y+35, and so is the second x. Adjacent angles add up to 180 total, and so to solve for y we need to plug 12 in the first x.
5(14)+25=95
180-95=85
85 is the value of 2y+35
We will solve for y just like any other alegrbaic problem
85=2y+35
50=2y
y=25
We know know that y is 25 and x is 14
Plug both values into 2 adjacent angles and they will add up to 180.

Explain how to find the change in temperature.
Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9
