with an x-intercept of 4?
y =
5
4 -3 -2 -1

Answer:

Option C. 50 square centimeters

Step-by-step explanation:

we know that

The surface area is equal to the area of four triangles plus the area of rectangle

so

[tex]SA=2[\frac{1}{2}(4)(2)]+2[\frac{1}{2}(6)(3)]+(6)(4)[/tex]

[tex]SA=8+18+24[/tex]

[tex]SA=50\ cm^{2}[/tex]

Answer:

C

Step-by-step explanation:

The total area comprises of the rectangle (area is base * height) and the 4 triangles (area = 1/2 * base * height).

Area of rectangle = 6 * 4 = 24

Area of top triangle = 1/2 * 6 * 3 = 9

Area of bottom triangle = 1/2 * 6 * 3 = 9

Area of rightside triangle = 1/2 * 4 * 2 = 4

Area of leftside triangle = 1/2 * 4 * 2 = 4

Let's add them up and find the correct answer:

Area = 24 + 9 + 9 + 4 + 4 = 50

Answer:

a) Current month's interest is: $40

b) The final payment is $7,440

c) Amount saved by paying off loan early is: $600

Step-by-step explanation:

Principal = $6,000

Interest rate = 8% or 0.08

Time = 36 months or 3 years

After 20 payments, the payment is $2,849.08.

a) What is the CURRENT month's interest?

The formula used to find the interest is:

I = P*r*t

Where P= Principal Amount

r = interest rate

and t = time in years

Putting the given values:

I = 6,000 * 0.08 * 3

I = 1440

Total Interest = $1440

Current Month interest = 1440/36

Current Month interest = 40

So, Current month's interest is: $40

b) What is the final payment?

The formula used is:

A = P(1+r*t)

A = 6,000(1+0.08*3)

A = 6000*(1.24)

A = 7,440

So, the final payment is $7,440

c) How much is saved by paying off the loan early?

The current balance paid is $2,849.08

The loan is paid when next payment is due.

So, remaining amount to be paid is:

Remaining Amount = Final Payment - Current balance paid

Remaining Amount = 7,440 - 2,849.08

Remaining Amount = 4,590.92

Remaining months in which amount is to be paid: 36-20 = 16 months

The loan is paid off next month so interest rate of remaining 15 months = 15*40 = 600

The amount paid on next payment = 4590.92 - 600 = $3990.9

So, amount saved by paying off loan early is: $600

Final answer:

Lionel Cooper saved $136.63 by paying off his loan early. The current month's interest on his loan was $19.09, making his final payment $2,868.17 after paying off the remaining balance of $2,849.08.

Explanation:

Lionel Cooper paid for new mechanic's tools with an installment loan of $6,000 at 8% annual interest rate for 36 months, with monthly payments of $187.80. After 20 payments, he decides to pay off the remaining balance of $2,849.08.

a.) What is the CURRENT month's interest?

First, calculate the monthly interest rate, which is 8% annually, or 0.08/12 per month = 0.0067. The current month's interest is the balance multiplied by the monthly interest rate: $2,849.08 * 0.0067 = $19.09.

b.) What is the final payment?

The final payment is the sum of the current month's interest plus the remaining balance: $19.09 (interest) + $2,849.08 (balance) = $2,868.17.

c.) How much is saved by paying off the loan early?

Normally, Lionel would pay $187.80 for 16 more months, totaling $3,004.80. By paying off early, he only paid $2,868.17, so he saved $136.63.

We have been given the following functions:

f(x) = 3x - 9

g(x) = x

(G*f) means to multiply the function of g and f together:

x(3x - 9)

3x^2 - 9x

Now multiply the product of the solution above by 5:

5(3x^2 - 9x)

15x^2 - 45x

So,  (g*f)(5) = 15x^2 - 45x

Answer:

6

Step-by-step explanation:

Substitute x = 5 into f(x) then substitute the value obtained into g(x)

f(5) = (3 × 5) - 9 = 15 - 9 = 6, then

g(6) = 6

Hence (g ￮ f)(5) = 6

Answer:

[tex]f(x)=(x-5)^{2}+19[/tex]

Step-by-step explanation:

we have

[tex]f(x)=x^{2}-10x+44[/tex]

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]f(x)-44=x^{2}-10x[/tex]

Complete the square. Remember to balance the equation by adding the same constants to each side.

[tex]f(x)-44+25=x^{2}-10x+25[/tex]

[tex]f(x)-19=x^{2}-10x+25[/tex]

Rewrite as perfect squares

[tex]f(x)-19=(x-5)^{2}[/tex]

[tex]f(x)=(x-5)^{2}+19[/tex]

Answer:

Inverse of y=x^3 is f^-1(x) = ∛x

Step-by-step explanation:

We need to find the inverse of y=x^3

Step 1:

Interchange the variables:

x= y^3

Step 2: Now solve to find the value of y

=> y^3 = x

taking cube root on both sides of the equation

∛y^3 = ∛x

y=∛x

Step 3: Replace y with f^-1(x)

f^-1(x) = ∛x

So inverse of y=x^3 is f^-1(x) = ∛x

Answer:

The measure of arc AC  is equal to 33°

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

so

∠ABC=(1/2) arc AC

substitute the values

(2.5x+4)=(1/2)(7x-2)

solve for x

5x+8=7x-2

7x-5x=8+2

2x=10

x=5

Find the measure of arc AC

arc AC=(7(5)-2)=33°

Final answer:

The measure of arc AC can be calculated by using the inscribed angle theorem and solving the equation 2×(2.5x + 4) = 7x - 2, which represents the relationship between the inscribed angle and its intercepted arc.

Explanation:

To determine the measure of arc AC, we need to consider the relationship between the inscribed angle of a circle (ABC in this case) and the corresponding arc (arc AC).

By the inscribed angle theorem, the measure of an inscribed angle is half the measure of its intercepted arc. This relationship allows us to set up the equation (2.5x + 4) degrees = 0.5×((7x-2) degrees).

By solving this equation, we can find the value of x, and consequently, the measure of arc AC.

substitute the values

(2.5x+4)=(1/2)(7x-2)

solve for x

5x+8=7x-2

7x-5x=8+2

2x=10

x=5

Find the measure of arc AC

arc AC=(7(5)-2)=33°

ANSWER

Answer:

[tex]|m-32|\leq 8[/tex]

Range: [tex]24\leq m\leq 40[/tex]

Step-by-step explanation:

Let m represent cost of medication.

We have been given that a pharmacy claims that the average medication costs $32 but it could differ as much as $8.

[tex]|\text{Actual}-\text{Ideal}|\leq \text{tolerance}[/tex]

[tex]|m-32|\leq 8[/tex]

Using absolute value inequality definition, if [tex]|u|\leq a[/tex], then [tex]-a\leq u\leq a[/tex], we will get:

[tex]-8\leq m-32\leq 8[/tex]

[tex]-8+32\leq m-32+32\leq 8+32[/tex]

[tex]24\leq m\leq 40[/tex]

Therefore, the range of medication costs at the pharmacy is [tex]24\leq m\leq 40[/tex].

Answer:

[tex]x^\frac{5}{3} y^\frac{1}{3}[/tex]

Step-by-step explanation:

This question is on rules of rational exponential

where the exponential is a fraction, you can re-write it using radicals where the denominator of the fraction becomes the index of the radical;

General expression

[tex]a^\frac{1}{n} =\sqrt[n]{a}[/tex]

Thus    [tex]\sqrt[3]{x} =x^\frac{1}{3}[/tex]

Applying the same in the question

[tex]\sqrt[3]{x^5y} =x^\frac{5}{3} y^\frac{1}{3}[/tex]

=[tex]x^\frac{5}{3} y^\frac{1}{3}[/tex]

Answer: Second option

[tex](x^5y)^{\frac{1}{3}} = x^{\frac{5}{3}}y^{\frac{1}{3}}[/tex]

Step-by-step explanation:

By definition we know that:

[tex]a ^{\frac{m}{n}} = \sqrt[n]{a^m}[/tex]

In this case we have the following expression

[tex]\sqrt[3]{x^5y}[/tex]

Using the property mentioned above we can write an equivalent expression for [tex]\sqrt[3]{x^5y}[/tex]

[tex]\sqrt[3]{x^5y} = (x^5y)^{\frac{1}{3}}[/tex]

[tex](x^5y)^{\frac{1}{3}} = x^{\frac{5}{3}}y^{\frac{1}{3}}[/tex]

Therefore the correct option is the second option

If you want calculate it, then:

The vectors AB and DC are congruent and the vectors BC and AD are congruents too.

If a vector ,< a, b > is congruent to a vector < c, d >, then a = c and b = d.

The formula of coordinates of the vetror:

< x₂ - x₁, y₂ - y₁ >

We have A(-2, 4), B(1, 3), C(4, -1) and D(x, y). Substitute:

vector AB = < 1 - (-2), 3 - 4 > = < 3, -1 >

vector DC = < 4 - x, -1 - y >

vector BC = < 4 - 1, -1 - 3 > = < 3, -4 >

vector AD = < x - (-2), y - 4 > = < x + 2, y - 4 >

Therefore we have the equations:

AB = DC ⇒ 4 - x = 3 and -1 - y = -1 ⇒ x = 1 and y = 0

BC = AD ⇒ x + 2 = 3 and y - 4 = -4 ⇒ x = 1 and y = 0
