Answer:

37.5 [tex]units^2[/tex]

Step-by-step explanation:

As the area of each of the side of the cube are the same we can multiply the area of one side by 6.

The area of one side is

[tex]2.5*2.5=6.25\\\\6.25*6=37.5[/tex]

Answer:

37.5

Step-by-step explanation:

Surface area of a rectangular prism (a cube is a rectangular prism) is 2B + Ph

B is area of the base so do width x length. In cube all side lengths are the same, so do 2.5 x 2.5.

B= 6.25

P is perimeter of base so do 2.5 + 2.5 + 2.5 + 2.5 = 10

P=10

h is the height of the prism, but all sides are the same anyway so it's 2.5

h=2.5

2(6.25) + 10(2.5)

12.5 + 25

37.5

The polynomial would be p(x) = x⁴ - 12x³ + 55x² -116x + 102

How to write the polynomial with these roots?

We know that the roots must be:

2± √2i and 4 ± i

Then we can write the polynomial as:

p(x) = (x - 2- √2i)*(x - 2+√2i)*(x - 4+i)*(x - 4 - i)

Notice that when x equals any of the roots, the polynomial becomes zero, now just expand the products, we will get:

p(x) = (x - 2- √2i)*(x - 2+√2i)*(x - 4+i)*(x - 4 - i)

p(x) = ((x-2)² + 2 )*( (x - 4)² + 1)

p(x) = (x² - 4x + 4 + 2)*(x² - 8x + 16 + 1)

p(x) = (x² - 4x + 6)*(x² - 8x + 17)

p(x) = x⁴ - 12x³ + 55x² -116x + 102

Final answer:

Mariana can spend a maximum of $1,050.00 per month on credit cards and loans to avoid credit overload, which is 20% of her annual take-home pay divided by 12 months.

Explanation:

Mariana's annual take-home pay is $63,000. To avoid credit overload, financial advisors often recommend that no more than 20% of your annual take-home pay should go towards servicing debt. To determine the monthly amount Mariana can safely allocate to pay off credit cards and loans, we first calculate 20% of her annual take-home pay, and then divide that number by 12 to get the monthly amount.

First, calculate the annual amount: 20% of $63,000 = 0.20 \(*\) $63,000 = $12,600.

Next, calculate the monthly amount: $12,600 / 12 months = $1,050.00 per month.

Therefore, the maximum amount Mariana can spend per month on debt repayment to avoid credit overload is $1,050.00.

Answer:

3. 2000 pounds to 600 pounds and 5. 250 cents to 75 cents

Step-by-step explanation:

The ratio is 10:3 so just multiply the first number by ten and the and the second by 3 to see if it matches

ex. 10 x 200= 2000    3 x 200= 600

10 x 25=250   3 x 25= 75

I hope this makes sense, this is kinda hard to physically explain.

The ratio 2000 pounds to 600 pounds and 250 cents to 75 cents are equivalent to 10:3.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b.

Final answer:

8/4 of a dollar is equivalent to 2 dollars, as 1/4 of a dollar is 0.25 dollars and multiplying this by 8 yields 2.

Explanation:

The question, what is 8/4 of a dollar?, falls under the category of elementary Mathematics, specifically fractions and monetary equivalence. To find the value of 8/4 of a dollar, you first need to understand that 4 quarters make up a dollar, which means that each quarter is worth 0.25 dollars or 25 cents. Therefore, to compute 8/4 of a dollar, you simply multiply 8 by the value of 1/4 of a dollar (0.25 dollars).

Here is the step-by-step calculation:

Understand that 1 quarter is 0.25 dollars.

Multiply 8 by 0.25 (1 quarter): 8 x 0.25 = 2.

So, 8/4 of a dollar is the same as 2 dollars

Answer:

[tex]\sqrt{\frac{x}{4}}[/tex]  and  [tex]-\sqrt{\frac{x}{4}}[/tex]

Step-by-step explanation:

The function is given as  [tex]f(x)=4x^2[/tex]

to find inverse, we follow the steps shown below:

1. write "y" in place of "f(x)"

2. interchange "x" and "y"

3. solve for the new "y"

4. replace y with f^-1(x)

Let's do this:

[tex]f(x)=4x^2\\y=4x^2\\x=4y^2\\y^2=\frac{x}{4}\\y=+-\sqrt{\frac{x}{4}}[/tex]

These 2 are the inverse functions.

For this case we must find the inverse of the following function:

[tex]f (x) = 4x ^ 2[/tex]

We follow the steps below:

Replace f (x) with y:

[tex]y = 4x ^ 2[/tex]

We exchange variables;

[tex]x = 4y ^ 2[/tex]

We solve for y:

[tex]4y ^ 2 = x[/tex]

We divide between 4 on both sides of the equation:

[tex]y^ 2 = \frac {x} {4}[/tex]

We apply square root to both sides to eliminate the exponent:

[tex]y = \pm \sqrt {\frac {x} {4}}[/tex]

We substitute y for [tex]f ^ {- 1} (x)[/tex]:

 [tex]f ^ {- 1} (x) =\pm \sqrt {\frac {x} {4}}[/tex]

Answer:

Part 1) Option A. The axis of symmetry is x=4

Part 2) Option C. minimum

Part 3) Option A. (4,-4)

Part 4) Option B. (2,0) and (6,0)

Step-by-step explanation:

we have

[tex]f(x)=x^{2}-8x+12[/tex]

Part 1) What is the axis of symmetry of the parabola described by the equation above?

we know that

The equation above is a vertical parabola open upward

The axis of symmetry is the x-coordinate of the vertex

Find the vertex of the parabola (convert the equation in vertex form)

[tex]f(x)-12=x^{2}-8x[/tex]

[tex]f(x)-12+16=x^{2}-8x+16[/tex]

[tex]f(x)+4=x^{2}-8x+16[/tex]

[tex]f(x)+4=(x-4)^{2}[/tex]

[tex]f(x)=(x-4)^{2}-4[/tex] ----> equation in vertex form

The vertex of the parabola is (4,-4)

so

The axis of symmetry is x=4

Part 2) The vertex of the equation above is also

we know that

The equation above is a vertical parabola open upward

therefore

The vertex is a minimum

Part 3) What is the vertex of the parabola described by the equation above

we know that

The equation of the parabola into vertex form is equal to

[tex]f(x)=(x-4)^{2}-4[/tex]

therefore

The vertex of the parabola is (4,-4)

Part 4) What are the  x-intercepts of the parabola described by the equation above

we know that

The x-intercepts are the values of x when the value of y is equal to zero

so

[tex]f(x)+4=(x-4)^{2}[/tex]

f)x)=0

so

[tex]4=(x-4)^{2}[/tex]

take square root both sides

[tex](x-4)=(+/-)2[/tex]

[tex]x=4(+/-)2[/tex]

[tex]x=4(+)2=6[/tex]

[tex]x=4(-)2=2[/tex]

therefore

The x-intercepts are

(2,0) and (6,0)

You appear to be missing side A. Here is the equation for that:

a = √(c² - b²)

So do c squared (13 squared) - b squared (12 squared)

= 25

However, the answer is not c squared - b squared, but the SQUARE ROOT of c squared - b squared.

In other words, we want the square root of 25, so your answer is...

Answer:

25°

Step-by-step explanation:

The angle shown in a right angle, which is 90°. Let's start with 3x-10. We want to get rid of the 10 so we add 10 as positive and negative cancel each other out. So when we add 10 to 90 we have 100. Now we have x+3x=100. Simplify that to 4x=100. Divide both sides by 4 to isolate the x and the answer is 25. To double check,

• 25×3=75

•75-10=65

•65+25=90

The whole angle is equal to 90 degrees therefore you can make an equation using the two angle values and set it equal to 90 like so...

x + 3x - 10 = 90

Combine like terms ( x and 3x)

(x + 3x) - 10 = 90

4x - 10 = 90

Bring the 10 to the other side by adding it to both sides

4x + (-10 + 10) = 90 + 10

4x + 0 = 100

4x = 100

To further isolate x divide 4 to both sides

4x/4 = 100/4

x = 25
