The correct equation is simply just X=3 :)

Answer:

x=3

Step-by-step explanation:

y = mx + b

m = (y2 - y1)/(x2 - x1)

m = (8+4)/(3-3) = 12/0 = UD

x = 3

x + 4y = 23
-2x + 3y = -2

Answers

Answer:

(x, y) = (7, 4)

Step-by-step explanation:

I find a graphing calculator to give a solution quickly and easily.

(x, y) = (7, 4)

Here, we can solve the first equation for x, then substitute into the second.

x = 23 -4y

-2(23 -4y) +3y = -2 . . . . . substitute for x

-46 +8y +3y = -2 . . . . . eliminate parentheses

11y = 44 . . . . . . . . . . . collect terms

y = 4 . . . . . . . . . . . . divide by the coefficient of y

x = 23 -4·4 = 7 . . . . use the expression for x to find x

(x, y) = (7, 4)

A water tank is a cube of side 2m the depth of water in it is60cm. What is the volume of water in the tank?

Answers

Answer:

Step-by-step explanation:

The base is made of a square that is 2 meters by 2 meters.

Base = 4 m^2

The height of the water is 60 cm

60 cm// 100 cm/meter = 0.6 meters

Volume = Base * height

Base = 4m^2

height = 0.6 m

Volume = 4 * 0.6 = 2.4 m^3

ACME insurance company estimates that the probability of the owners’ of a house worth between $120,000 to $170,000 making a claim for $5000 is 0.08, and that the probability of the house and contents being totally destroyed is 0.0041. Should that tragedy happen, the company will have to pay $150,000. The company charges $1300 for the insurance policy.

What is the expected value of this policy to the insurance company?

Round your answer to two decimal places.

Answers

The expected value of this policy to the insurance company is $285.00.

Using this formula

Policy expected value=Insurance policy charges-[(Probability × Claim)+(Probability × Claim)]

Let plug in the formula

Policy expected value=$1,300-{(.0041)($150,000)+(.08)($5,000)]

Policy expected value=$1,300-($615+$$400)

Policy expected value=$1,300-$1,015

Policy expected value=$285.00

Inconclusion the expected value of this policy to the insurance company is $285.00

Juanita is tying ribbon on gift bags. She has 24 feet of ribbon and each gift bag uses 0.75 foot of ribbon. The function

r = 24 -0.75g represents the amount of ribbon r Juanita has left after tying ribbon on g gift bags. Find the zero of the function. Describe

what this value means in the context of this situation

The zero of the function is at ___. This represents that after tying ribbon on ____ gift bags, Juanita will have ____ feet of ribbon left.

Answers

The zero of the function is at 32 gift bags. This represents that after tying ribbon on 32 gift bags, Juanita will have zero feet of ribbon left.

According to the question;

The function r = 24 -0.75g represents the amount of ribbon r Juanita has left after tying ribbon on g gift bags.

The zero of the function is at, r = 0.

Therefore;

0 = 24 -0.75g

g = 24/0.75

g = 32.

This value means that after tying 32 gift bags, Juanita will have zero feet of ribbon left.

If f(1) = 10 and f '(x) ≥ 3 for 1 ≤ x ≤ 6, how small can f(6) possibly be?

Answers

Answer:

[tex]f'( x ) = \frac{f(b) - f(a)}{b - a} \\ = \frac{f(6) -f(a)}{6 - 1} \\ 3\leqslant \frac{f(6) - 10}{5} \\ 15\leqslant f(6) - 10 \\ f(6) \geqslant 15 + 10 \\ f(6) \geqslant 25[/tex]

Answer:

Step-by-step explanation:

Our "best" case is when [tex]f'(x) = 3[/tex] everywhere - if it changes it means [tex]f(x)[/tex] will grow faster. But if [tex]f'(x)[/tex] is constant, it means [tex]f(x)[/tex] is the straight line [tex] y-10 = 3 (x-1) [tex], which passes through the point (6, 25)

You deposit $9000 in an account that pays 5% interest compounded quarterly.

A. Find the value of one year

B.Use the future value formula for simple interest to determine the effective annual yield
(Formula: A=P(1 +rt)

Answers

Step-by-step explanation:

Given:

Deposit P = $9000Interest rate r = 5% = 0.05Time t = 1 yearNumber of compounds n = 4

A. Find the value of one year

[tex]A = P(1 + r/n)^{nt} = 9000(1+0.05/4)^4=9458.51[/tex]

B. Use the future value formula for simple interest to determine the effective annual yield

[tex]A=P(1+rt)\\[/tex][tex]r=(A/P-1)/t[/tex][tex]r=(9458.51/9000-1)/1=0.0509[/tex] r = 5.1%

Answer:

A) $9458.51

B) 5.09% (2 d.p.)

Step-by-step explanation:

Part A

Compound Interest Formula

[tex]\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}[/tex]

where:

A = final amountP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsed

Given:

P = $9000r = 5% = 0.05n = 4 (quarterly)t = 1 year

Substitute the given values into the formula and solve for A:

[tex]\implies \sf A=9000\left(1+\frac{0.05}{4}\right)^{4 \times 1}[/tex]

[tex]\implies \sf A=9000(1.0125)^4[/tex]

[tex]\implies \sf A=9458.508032...[/tex]

Therefore, the value of the account after 1 year is $9458.51.

Part B

Simple Interest Formula

A = P(1 + rt)

where:

A = final amountP = principalr = interest rate (in decimal form)t = time (in years)

Given:

A = $9458.51P = $9000t = 1 year

Substitute the given values into the formula and solve for r:

[tex]\implies \sf 9458.51=9000(1+r(1))[/tex]

[tex]\implies \sf 9458.51=9000(1+r)[/tex]

[tex]\implies \sf \dfrac{9458.51}{9000}=1+r[/tex]

[tex]\implies \sf r=\dfrac{9458.51}{9000}-1[/tex]

[tex]\implies \sf r=0.050945...[/tex]

[tex]\implies \sf r=5.0945... \%[/tex]

Therefore, the effective annual yield is 5.09% (2 d.p.).
