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:

C. 10 units

Step-by-step explanation:

The half diagonals of a rhombus are the legs of a right triangle with the hypotenuse being the side of the rhombus.

EG and FH are the diagonals of the rhombus. The half-diagonals measure 8 and 6.

We can use the Pythagorean theorem to find the hypotenuse length with is the length of the side of the rhombus.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = c^2

100 = c^2

c^2 = 100

c = 10

Answer: 10 units

The length of one side of the rhombus is 10 units.

A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.

Given that,

EFGH is a rhombus.

Length of the two diagonals are also given.

EG = 16 and FH = 12

In a rhombus, the diagonals bisect each other at right angles.

Let the intersection point of the diagonals be O.

Consider ΔOFG.

Using Pythagoras Theorem,

(FG)² = (OG)² + (OF)²

OG = EG / 2 = 16 / 2 = 8

OF = FH / 2 = 12 / 2 = 6

(FG)² = 8² + 6²

        = 100

FG = √100 = 10

Hence the length of one side of the rhombus is 10 units.

Look at the other pictures

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

Hope my answer has helped you and if not i'm sorry.

Step-by-step explanation:

If (p, 0) and (q, 0) are x-intercepts, then p and q are zeros.

The intercept form of an equation of a quadratic function:

y = a(x - p)(x - q)

p, q - x-intercepts (zeros).

We have the equation: y = 2(x + 4)(x - 6) = 2(x - (-4))(x - 6)

Therefore the x-intercepts are -4 and 6.

The zeros are -4 and 6 too.

Answer:

Around $93.65

Step-by-step explanation:

(1 - 37%)(x) = 59

(0.63)(x) = 59

x = 93.65

Final answer:

To find the original price of the printer before a 37% discount, we set up an equation and solve for the original price. After solving, the original price is found to be approximately $93.65.

Explanation:

To calculate the original price of the printer before the discount, we need to understand that the sale price represents 100% - the discount percentage of the original price. Given that the sale price is $59 after a 37% discount, we set up an equation where the original price (which we'll call P) minus 37% of P equals $59.

The equation looks like this: P - 0.37P = $59. We can simplify this equation by combining like terms, which gives us 0.63P = $59. To find P, we then divide both sides of the equation by 0.63, leading us to the original price.

Let's do the math:

The original price of the printer is calculated to be approximately $93.65.

The probability of drawing three queens in a row from a standard deck of cards, starting with the first card drawn as a queen and with no replacement, is approximately 0.0181% or 0.000181.

The probability of drawing a queen from a deck of 52 cards, given that the first card drawn was a queen and that cards are not replaced, involves a combination of multiplying probabilities for independent events:

To find the total probability of drawing three queens in a row, we multiply these independent probabilities together: (1/13) * (3/51) * (2/50). This totals to approximately 0.000181, or 0.0181%, which is the probability of drawing three queens in a row from a standard deck of cards without replacement after drawing the first queen.

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

Final answer:

The function f(x) = 2x^3 – x^2 – 6x is found by factoring the function, resulting in the zeros at x = 0, x = -3/2, and x = 2.

Explanation:

To find the zeros of the function f(x) = 2x^3 – x^2 – 6x, we must set the function equal to zero and solve for x. If possible, this can be done by factoring the function or using synthetic division. In this case, the function can be factored by taking out a common factor of x:

f(x) = x(2x^2 - x - 6) = 0

Next, we can factor the quadratic equation 2x^2 - x - 6 to find the remaining zeros:

2x^2 - x - 6 = (2x + 3)(x - 2)

This gives us the following zeros for the function:

x = 0

x = -3/2

x = 2

Therefore, f(x) has three zeros: 0, -1.5 (or -3/2), and 2.

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.

Inequality which represents the number of sodas is 0 ≤ s ≤ 3.

Given:

Cost of soda = $2.75

Cost of bottled water = $2.00

2.75s + 2w ≤ 15

Let, number of sodas be s.

number of bottled water be w.

Three Alexandra's friends asked for water.

∴ w = 3

⇒ 2.75s + 2(3) ≤ 15

⇒ 2.75s + 6 ≤ 15

Subtracting 6 from the both sides, we get:

⇒ 2.75s ≤ 15 - 6

⇒ 2.75s ≤ 9

Divide both sides by 2.75, we get:

⇒ s ≤ 9/2.75

⇒ s ≤ 3.27

But the number of sodas (s) should be a whole number and not an integer.

⇒ s ≤ 3
