let f(x)=4+3x and g(x)=x^2-3. find each function value: (f+g)(-4)

Answers

Answer 1

Answer:

Step-by-step explanation:

You are going to want to substitute the x of the function f(x) with the function of g(x) and replace the x in g(x) with -4

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

=43

Answers

Right format of question:

Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.

Answer:

[tex]D' = (-4,-6)[/tex] and [tex]D' = (-4,8)[/tex]

Step-by-step explanation:

Given

[tex]D(x,y) = (-4,1)[/tex]

Required

Determine a point 7 points from D and in the same x coordinate

Represent this point with D'.

From the requirement of the question, D' has two possible values and these values are:

[tex]D' = D(x,y-7)[/tex] ----> 7 units down and

[tex]D' = D(x,y+7)[/tex] ----> 7 units up

Substitute values for x and y in [tex]D' = D(x,y-7)[/tex] and [tex]D' = D(x,y+7)[/tex]

So, we have:

[tex]D' = D(x,y-7)[/tex]

[tex]D' = (-4,1 - 7)[/tex]

[tex]D' = (-4,-6)[/tex]

[tex]D' = D(x,y+7)[/tex]

[tex]D' = (-4,1+7)[/tex]

[tex]D' = (-4,8)[/tex]

PLEASE HELP ME ANSWER The probability that Scott will be late for work is 0.15. In a year Scott works for 240 days. Work out the expected number of days that he will be late......

Answers

Answer:

36 days

Step-by-step explanation:

Given

[tex]p = 0.15[/tex] -- probability of coming late to work

[tex]n = 240[/tex] -- number of days

Required

Determine the expected number of days of coming late (E(x))

This is calculated using:

[tex]E(x) = np[/tex]

[tex]E(x) = 240 * 0.15[/tex]

[tex]E(x) = 36[/tex]

can that be possible, when the multiplication table only
goes to 9?

Answers

Answer:

See below, please!

Step-by-step explanation:

There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.

For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?

Step-by-step explanation:

Solve 64 = h + 30.
K=?

Answers

Answer:

h = 34

Step-by-step explanation:

64=h+30

Step 1: Flip the equation.

h+30=64

Step 2: Subtract 30 from both sides.

h+30−30=64−30

h=34

Assuming you meant “h =?” instead of “K=?”. In that case,
h = 34.

To find this answer, you just subtract 30 from 64, isolating h on it’s own side. Or imagine the problem arranged “h + 30 = 64.”

8units²

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the opposite sides

h is the height

Take a square as 1 unit

a = 1 unit

b = 3 units

height h = 4 units

Substitute

A = 1/2(1+3)*4

A = 1/2 * 4 * 4

A = 16/2

A = 8units²

Hence the area of the trapezoid is 8units²

WHAT ARE THE PRINCIPALS PLEASE HELP ME!

You have 2 different savings accounts. For Account A, the simple interest earned after
6 months is $4.63. For Account B, the simple interest earned after 21 months is $16.80. If the interest rate is 3.7% for Account A and 2.4% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.

Answers

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount of money invested.

R represents interest rate

T represents time

Considering the investment on account A,

I = $6.94

R = 3.7%

T = 9 months = 9/12 = 0.75 years

6.94 = (P × 3.7 × 0.75)/100 = 0.02775P

P = 6.94/0.02775 = $250

Considering the investment on account B,

I = $13.80

R = 2.3%

T = 18 months = 18/12 = 1.5 years

13.8 = (P × 2.3 × 1.5)/100 = 0.0345P

P = 13.8/0.0345 = $400

To determine the account that earned more interest in the first month,

250/9 = $27.8

400/18 = $22.2

Account A earned you the most interest the first month because $27.8 is higher than $22.2
