Given F(x) =3x+2 and g(x) = 2x2 , find the following composite functions:
a. (g*f)(3)
b. (f*g)(x)
Answer:
b. (f*g)(x)
Step-by-step explanation:
Set up the composite result function.
g ( f ( x ) )
Evaluate
g (f ( x ) )
by substituting in the value of
f into g . g ( 2 x 2 + 3 ) =3 ( 2 x 2 + 3 ) − 2
Simplify each term.
g ( 2 x 2 + 3 ) = 6 x 2 +9 − 2
Subtract
2 from 9 . g ( 2 x 2 + 3 ) = 6 x2+ 7
Answer: B
Step-by-step explanation:
Set up the composite result function.
g ( f ( x ) )
Evaluate
g (f ( x ) )
by substituting in the value of
f into g . g ( 2 x 2 + 3 ) =3 ( 2 x 2 + 3 ) − 2
Simplify each term.
g ( 2 x 2 + 3 ) = 6 x 2 +9 − 2
Subtract
2 from 9 . g ( 2 x 2 + 3 ) = 6 x2+ 7

Answer:
Pic 1: [tex]x=31[/tex]
Pic 2: [tex]x=20[/tex]
Step-by-step explanation:
Picture 1:
[tex]2x+x-3=90\\3x-3=90\\3x=93\\x=31[/tex]
First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
Picture 2:
[tex]7x+x+20=180\\8x+20=180\\8x=160\\x=20[/tex]
First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.
Step-by-step explanation:
First picture
We can make an equation with this
2x+x-3=90
3x=93
x=31 degrees
Second picture
We can make and equation
7x+x+20=180
8x=160
x= 20

Answer: 1 brain
Step-by-step explanation:
If one person has a brain, the number of brains they have, x, is 1.
Then, upon giving a brain to another person, x decreases by 1, becoming 0.
Then, when given a brain, x increases by 1, settling at 0.

Mr. Reynolds is a rancher. He started with a 150 cows in his herd. Due to a hole in his fence, he now has 120 cows in his herd. By what percentage was the number of cows in Mr. Reynold's herd reduced?
Answer:
20%
Step-by-step explanation:
Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".
Here given that,
Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.
Number of cows Mr. Reynolds have
[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %
So, the number of cows Mr. Reynolds reduced is
[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %
Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

I CANT HELP MY BROTHER SOLVE THIS QUESTION AND I DONT WANT HIM TO CALL ME D*UMB PLZ HELP
Answer:
yes
Step-by-step explanation:
7 weeks * 7 days per week = 49 days49 days * 2 meals per day = 98 total meals98 meals * 31 grams per meal = 3038 grams after 7 weeksAnswer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.
Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Please explain I am very confused!
Answer:
42°
Step-by-step explanation:
Altitude of an isosceles triangle divides it vertex in equal angles
so ∠ABD = ∠PBC = 48/2 = 24
In ΔABC sum of angles = 180 and ∠A = ∠C
48 + A + C = 180
2A = 180 - 48 = 132
A = 132/2 = 66 = ∠C
As PB = PC ---> ∠PBC = ∠PCB = 24
∠ACB = 66 = ∠PCD + ∠PCB
66 = ∠PCD + 24
∠PCD = 42

i. Statements b and d would map Shape l onto Shape IIii. Statements a, c, e, and f does not map Shape l onto Shape IITransformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.Translation is a method that requires moving every point in a given shape in the same direction and same unit.
Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased.Thus the answers to the question are listed as follows:
a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 18 units. Does not Map Shape l onto Shape IIb. a 90° clockwise rotation about the origin and then a translation left 18 units Answer: Maps Shape l onto Shape IIc. a 90° counterclockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation left 18 units d.

The Cost C (in dollars) of making n watches is represented by C=15n+85. How many watches are made when the cost is $385?
Answer:
The number of watches made is 8
Step-by-step explanation:
SO the equation is C=15n+85 where C is the total cost and N is the amount of watches
1)plug in C
385=15n+85
2)move 85 to the other side so it would become -85
385=15n+85 → 385-85=15n → 100=15n
3)divide 15 from both sides
100/15=15n/15 → 25/3=n
since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)
