Answer:

6

Step-by-step explanation:

(g o f)(3) = g(f(3))

We can find f(3) using its formula with x=3:

f(3) = -2·3 +8 = -6 +8 = 2

Now, we can find g(2) using its formula with x=2:

g(2) = 3·2 = 6

So, the composition value is ...

(g o f)(3) = 6

Answer:

(-2, 3 )

(-1, 2[tex]\frac{1}{2}[/tex])

(0, 2)

(1, 1[tex]\frac{1}{2}[/tex])

(2, 1)

Step-by-step explanation:

You just simply substitue the values given into the equation, and the answer worked out will be the value of y.

a = - [tex]\frac{1}{2}[/tex] × -2 + 2 = 1 + 2 = 3

b = - [tex]\frac{1}{2}[/tex] × -1 + 2 = [tex]\frac{1}{2}[/tex]  + 2 = 2[tex]\frac{1}{2}[/tex]

c =  -[tex]\frac{1}{2}[/tex] × 0 + 2 = 0 + 2 = 2

d = -[tex]\frac{1}{2}[/tex] × 1+ 2 =  -[tex]\frac{1}{2}[/tex]  + 2 = 1[tex]\frac{1}{2}[/tex]

e = -[tex]\frac{1}{2}[/tex] × 2+ 2 = -1 +2 = 1

Answer:

0.03

Step-by-step explanation:

Given the following :

Instructor __no of failure __prop (failure /100)

A ________ 13__________0.13

B ________0___________0

C________11___________0.11

D________16__________0.16

Prof. B adds no proportion to the data and hence excluded in the estimation.

Mean(m) = 0.13 + 0.11 + 0.16) / 3

= 0.4 / 3

= 0.1333

Standard deviation :

Σ(X - m)² / N - 1

Σ(0.13 - 0.1333)² + (0.11 × 0.1333)² + ( 0.16 - 0.1333)² = 0.0012668689

= 0.0012668689 / 2

= 0.00063343445

√0.00063343445

= 0.0251681

= 0.03 To 2 decimal places

Answer: f(30) = -1

You would substitute every X with 30

Answer:

-1

Step-by-step explanation:

First, plug in 30 to your equation (f(x) = 14 - 0.5(30)

0.5 • 30 is 15, so subtract 15 from 14 and you get -1

Answer:

f(g(3)) = 56

g(f(3)) = 25

Step-by-step explanation:

fog = f(2x+1)

f(2x+1) = (2x+1)^2 + 2x+1

(2x+1)^2 + 2x+1 = 4x^2+6x+2

f(g(x)) = 4x^2+6x+2

f(g(3)) = 4(3)^2+6(3)+2

f(g(3)) = 56

gof = g(x^2+x)

g(x^2+x) = 2(x^2+x)+1

2(x^2+x)+1 = 2x^2 + 2x + 1

g(f(x)) =  2x^2 + 2x + 1

g(f(3)) = 2(3)^2 + 2(3) + 1

g(f(3)) = 25

Answer:

X = 62

Step-by-step explanation:

The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like

(x + 1) + 55 + x = 180

Now you just solve.

Since there are 2 x's you can combine the like terms making them equal 2x

Now the equation should look like 2x + 1 + 55 = 180

Simplify the other like terms: 2x + 56 = 180

Now you want to get x by itself so you subtract 56 from both sides:

2x + 56 = 180

    -56      -56

------------------------

2x = 124

Now to finish getting x by itself, divide both sides by 2.

2x = 124

-----   ------

2         2

x = 62

FINALLY you plug in x to see if it worked.

(62 + 1) + 55 + 62 = 180

Answer:

Deductive

Step-by-step explanation:

Answer:

Nope because, wait did you forget a parenthesis to the left of -40?

But if there is no parenthesis, you don't have to distribute it.

If there are parenthesizes however, you would need to distribute it.

Answer:

72 weeks

Step-by-step explanation:

If 1 week =$10.75 then $774 will be equal to $774×1 week=774 then divide by $10.75=72 weeks

It will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.

We have - Roberto and Maria Santana's who spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and dryer would cost them a total of $774.

We have to determine in how many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer.

You will save $100 in = [tex]\frac{100}{5}[/tex]  = 20 days.

According to question, we have -

Cost of a Laundromat = $10.75/week

Total cost of a new washer and dryer = $774.

The number of weeks it will take for the laundromat cost to equal the cost of a new washer and dryer will be -

n(W) = [tex]\frac{774}{10.75}[/tex] = 72 weeks

Hence, it will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.
