Answers

Answer:

D: 64 x^27 y^125

Step-by-step explanation:

You can use either a calc or your knowledge of cube roots. I will be using knowledge.

You can automatically rule out a and b as if you take the cube root of 12, no whole number comes out. You are left with c and d. Option D is correct because the cube root of 64 is a whole number (4), the cube root of 27 is a whole number (3), and the cube root of 125 is also a whole number(5).

Answer:

Step-by-step explanation:

the answer is c

The statement must be true about parallelogram ABCD is BE ≅ DE option (C) BE ≅ DE is correct because the diagonals of a parallelogram bisect each other.

What is a Parallelogram?

A parallelogram is a polygon with four sides, opposite sides of the parallelogram are parallel.

The parallelogram ABCD is shown in the figure.

A parallelogram is a type of quadrilateral,

The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.

The parallelogram has two diagonals, AC and BD.

From the property of Parallelogram,

The diagonals of a parallelogram bisect each other.

So, AC and BD bisect each other.

AE = ECBE = CE

The correct answer is BE ≅ DE.

Thus, the statement must be true about parallelogram ABCD is BE ≅ DE option (C) BE ≅ DE is correct because the diagonals of a parallelogram bisect each other.

Factor the numerator

Critical points are

X =-3  X =2  X=7

We need to check the values when

x≤3  -3 ≤ x≤2           2 ≤x<7   x>7  

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

Step-by-step explanation:

Seth has just decided to replace his computer. His old computer cost him $1,433 when he bought it exactly seven years ago. Seth paid for it with his credit card, which has an APR of 11.70%, compounded monthly. He made no other purchases with the card and paid off his balance after two and a half years of making identical monthly payments. The computer consumed about $0.79 of electricity every day. In total, what percentage of the lifetime cost of the computer did the electricity make up? (Assume that two out of the seven years were leap years, and round all dollar values to the nearest cent.)
a.
82.157%
b.
58.500%
c.
21.718%
d.
54.898%


Please select the best answer from the choices provided.

A
B
C
D

Answers

Answer:

The answer is D

Step-by-step explanation:

The solution would be like this for this specific problem:

Cost of the computer:

i = 0.117 / 12 

i = 0.00975 

= monthly payment 

= (i * P * (1 + i)^n) / ((1 + i)^n - 1) 

= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1) 

= $55.32 

Electricity cost:

= $0.79 * 365.25 * 7 

= $2019.83 

Electricity Percentage: 

= $2019.83 / ($2019.83 + $1659.60) 

= 54.89% 

Electricity: 

= ($0.79 * 365 * 5) + ($0.79 * 366 * 2) 

= $2020.03 

 

Electricity Percentage: 

= $2020.03 / ($2020.03 + $1659.60) 

= 54.898%

In total, the electricity made up 54.898% of the lifetime cost of the computer.

A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?
____gallons

Answers

Answer:

1.548 gallons

Step-by-step explanation:

Length of the rectangular wall = 25.1 ft.

Width of the rectangular wall = 18.5 ft.

Area of the rectangular wall = length * width = 25.1 * 18.5

= 464.35 square feet

300 square feet wall can be painted using 1 gallon of paint.

=> 1 square feet wall can be painted using  gallon of paint.

=> 464.35 square feet wall can be painted using  gallon of paint.

= 1.548 gallons of paint

Answer:

4 gallons

Step-by-step explanation:

The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.

The segments shown below could form a triangle.

Answers

Answer:

A. True

Step-by-step explanation:

The Triangle Inequality Theorem says that the sum of any two sides must be greater than the third side. Let's see if this is true.

a + b

9 + 1 = 10>9

a + c

9 + 9 = 18>1

c + b

9 + 1 = 10>9

True, the segments shown below could form a triangle. Option A is correct.

What is the triangle?

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

According to the Triangle Inequality theorem, any two sides' total must be bigger than the third side. Verify one by one;

⇒a + b>c

⇒9 + 1 >9

⇒10>9

a + c>b

9 + 9 >1

18>1

c + b>a

9 + 1 >9

10>9

True, the segments shown below could form a triangle.

Hence, option A is correct.

For the real-valued functions, find the composition and specify its domain using interval notation.

Answers

Answer:

Composition:   [tex]f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]

Domain = { [tex]x\,/\,x\geq \,-4[/tex]  }

Step-by-step explanation:

Given

[tex]f(x)=4\,x-1\,\,\, and \,\,\, h(x)=\sqrt{x+4}[/tex]

The requested composition becomes:

[tex]f(x)\,^o\,h(x)=f(h(x))\\f(x)\,^o\,h(x)=f(\sqrt{x+4} )\\f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]

Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:

[tex]x+4\geq \,0[/tex]  (so the square root is defined in the Real number system)

This means [tex]x\geq \,-4[/tex]

The Domain is then all the Real x-values such that [tex]x\geq \,-4[/tex]

Answers

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

Find the other endpoint of the line segment with the given endpoint and midpoint.

Answers

Find the distance between the two x values: -10 to -7 is 3 units, so add to the midpoint: -7 + 3 = -4

The x value is -4

Now do the same for y:

Because the midpoint is less than the end point subtract:

Y = -3 -10 = -13

Y = -13

length of the hypotenuse is 7.1 centimeters. Answer parts a and b.
a. Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.​

Answers

Answer:

c ≅ 35.4 cm.

Step-by-step explanation:

To find the length of the Hypotenuse of a triangle, the formula  a² + b² = c² will need to be used. Therefore:

26² + 24² = c² (c is the hypotenuse)

1252 = c²

√1252 = c

c ≈35.38

Round to tenths place:

c ≅ 35.4 cm. This is the Hypotenuse of the triangle.
