Answer:
D) 12x^2+2
Step-by-step explanation:
As we are dealing with composite functions, the rule is that f(g(x)) means whatever the value of g(x) is, we substitute that value for x in f(x):
[tex]f(x)=3x^2+2\\g(x)=2x\\f(g(x))=3(2x)^2+2\\f(g(x))=3(4x^2)+2\\f(g(x))=12x^2+2[/tex]
So, f(g(x))=12x^2+2, making D the right answer
Answer:
the answer is the third possible answer
If you flip a coin and roll a 666-sided die, what is the probability that you will flip a heads and roll a 2?
Answer: [tex]\dfrac1{12}[/tex]
Step-by-step explanation:
Outcomes for tossing a coin =2 [tail and head]
Outcomes of rolling a 6-sided die =6
Total outcomes for rolling both = 2 x 6 = 12
Favorable outcomes for getting a head and 2 on die = 1
Probability = [tex]\dfrac{favorable\ outcome}{Total\ outcomes}[/tex]
Now , the probability that you will flip a heads and roll a 2 [tex]=\dfrac1{12}[/tex]
Hence, the required probability = [tex]\dfrac1{12}[/tex]

Sam has a rectangular rug with an area of 48 square feet. The rug is 8 feet longer than it is wide. What is the width of the rug?
Given:
Arear of rectangular rug = 48 sq. feet.
The rug is 8 feet longer than it is wide.
To find:
The width of the rug.
Solution:
Let x feet be the width of the rug.
The rug is 8 feet longer than it is wide.
Length of the rug = (x+8) feet
Area of a rectangle is
[tex]Area=Length\times Width[/tex]
Arear of rectangular rug is 48 sq. feet.
[tex]48=(x+8)\times x[/tex]
[tex]48=x^2+8x[/tex]
[tex]0=x^2+8x-48[/tex]
Splitting the middle term, we get
[tex]x^2+12x-4x-48=0[/tex]
[tex]x(x+12)-4(x+12)=0[/tex]
[tex](x+12)(x-4)=0[/tex]
Using zero product property, we get
[tex](x+12)=0\text{ and }(x-4)=0[/tex]
[tex]x=-12\text{ and }x=4[/tex]
Width cannot be negative. So, [tex]x=4[/tex].
Therefore, the width of the rug is 4 feet.
RST with vertices R(–2, 3), S(1, 2), and T(2, –1) is rotated 270° counterclockwise about the origin.
Answer:
vertices are rotation by 270° about the origin
R¹( 3, 2), S¹( 2, -1) and T¹ (-1,- 2)
Step-by-step explanation:
Explanation:-
The rule for a rotation by 270° about the origin is
( x,y) → (y,-x)
Given vertices are R(–2, 3), S(1, 2), and T(2, –1)
Given vertices are rotation by 270° about the origin
R¹( 3,-(-2)) , S¹( 2 , -1) and T¹ (-1 , -(2))
R¹( 3, 2), S¹( 2,-1) and T¹ (-1,- 2)
2(x + 5) = 3x + 1 I need help. Its saying that the answer is 9. When I typed in 9, it says explain how you got it.
Answer:
Step-by-step explanation:
just solve the equation
2x+10=3x+1
we will subtract 10 from one side and 3x from the other
2x-3x=-10+1
-x=-9 we will multiply by negative 1
x=9
you got the answer by solving the equation and find the value of x

The Slow Fix auto shop charges $28 for parts and $48 per hour of labor. The We Work Cheaper auto shop charges $59 for parts and $44.90 per hour of labor. For how many hours will the total cost the same for both auto shops?
Answer: 10 hours
Step-by-step explanation:
Given
Slow fix auto charge $28 for parts and $48 per hour of labor
We work charge $59 for parts and $44.90 per hour of labor
Suppose both works for x hours
Cost of Slow fix= [tex]\$(28+48x)[/tex]
Cost of We work= [tex]\$(59+44.90x)[/tex]
When these costs are the same
[tex]28+48x=59+44.90x\\3.1x=31\\x=10\ hours[/tex]

3x - 6y = -48 and 2x + 3y = 38 How would I solve by substitution?
Answer:
(4,10)
Step-by-step explanation:
3x-6y= -48
3x=6y-48
x=2y-16
2(2y-16)+3y=38
4y-32+3y=38
7y=70
y=10
3x-6(10)=-48
3x=12
x=4

10% of the passengers on a fly with us airlines flight are in first class. If there are 40 passengers in first class, how many total passengers are on the flight
Answer:
400 passengers
Step-by-step explanation:
To solve the problem, a proportion would be best!
First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:
[tex]\frac{10p}{100w}[/tex] (with p standing for part and w standing for the whole)
Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:
[tex]\frac{10p}{100w} = \frac{40p}{x}[/tex]
To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!

Ethan's football team scored a total of 35 separate times this season, with a mix of touchdowns and field
goals. Each touchdown is worth 7 points, and each field goal is worth 3 points. If the team scored a total of
193 points this season, how many touchdowns and field goals did they score?
9514 1404 393
Answer:
22 touchdowns13 field goalsStep-by-step explanation:
Let t represent the number of touchdowns scored. Then 35-t is the number of field goals, and the total score is ...
7t +3(35 -t) = 193
4t = 88 . . . . . . . . . . simplify, subtract 105
t = 22
35 -t = 13
The team scored 22 touchdowns and 13 field goals.
