Step-by-step explanation:

Answer:

0 is a value of a for 7/a to make irrational number.

Answer:

24

Step-by-step explanation:

Given the following car options :

Number of doors = (2 - door, 4 - door) = 2 options

Color = 6 different options

Interior design = two options

To obtain the total Number of option combination ; we apply the rule of product;

Number of door option * Number of color option * number of interior design option

(2 * 6 * 2) = 24 different option combination can be made by the manufacturer.

Answer:

4 cups

Step-by-step explanation:

Given the point (8, 1 )

This tells us that 1 cup can be filled using 8 fluid ounces

Divide 32 by 8 to find number of cups

32 ÷ 8 = 4

Then 4 cups can be filled from 32 fluid ounces

Plot the point (32, 4 ) on the grid

Answer:

1). 4 glasses

2). The graph of a line whose equation is; y = [tex]-\frac{1}{8}x + \frac{63}{64}[/tex]

Step-by-step explanation:

The container has 32 fl oz of orange juice.

He is filling glasses with the juice; such that each glass will hold one cup of the juice.

From the graph, 8 ounces of juice goes into one cup (equivalent of one glass)

So we expect Enrique to fill 32 ÷ 8 = 4 glasses

The graph is the line passing through points (8,1) and (32,4) whose equation is;

y = [tex]-\frac{1}{8}x + \frac{63}{64}[/tex]

Answer:

n(k + m) = number of fruits

Step-by-step explanation:

n(k + m)

Remember that the fruits combined would be k + m.

Then to find the total, you would need to multiply by the number of plates, which is n. Therefore, you would get n(k+m) to showcase the total amount of fruits on the table.

Answer:

height:6

if the base is a square that means all the side lengths are equivalent so it would be 8 for side lengths, and the volume is 128. plug it in with the formula to get 6

The height of a pyramid is 8cm

Supposing that:

The length of the sides of the square base the pyramid has = b units

The height of the considered square based pyramid = h units,

Then, its volume is given by: [tex]V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3[/tex]

Given;

The volume of pyramid= 128cm3

Length of side of square base= 8cm

Now,

128=1/3 x 8x8xh

128= 64/3 xh

h= 128x3/64

h=8

Therefore, the height with the volume 128cm3 will be 8cm

Vertex: -3, -1

Focus: -3, 1

Vertex of the parabola is (-3,-1)

Focus is (-3,1)

Given parabola equation is x^2+6x-8y+1=0

x^2+6x = 8y-1

x^2+6x+9 = 8y-1+9

(x+3)^2 = 8y+8

(x+3)^2 = 8(y+1)

(y+1) = 1/8 (x+3)^2

Here vertex V(h,k) = (-3,-1)

Focus = (-3,1)

Hence, Vertex of the parabola is (-3,-1)

Focus of the parabola is(-3,1)

Answer:

{−2, 0, 4}

Step-by-step explanation:

[tex]\displaystyle 6x^3 - 12x^2 - 48x \\ 6x[x^2 - 2x - 8] \\ 6x[x + 2][x - 4] \\ \\ 0, 4, -2 = x[/tex]

I am joyous to assist you at any time.

The roots of the cubic polynomial 6x³ - 12x² - 48x  = 0 are  -2, 0 and 4.

The degree of a cubic polynomial is 3. Degree of a polynomial is the highest power of the variable in that polynomial. In cubic polynomial, the variable [x] has the highest power of 3 (x³).

Given is the following cubic polynomial -

6x³ - 12x² - 48x  = 0

In order to find the roots of this cubic equation, we will plot its graph. The number of y - intercepts [coordinates where the graph cuts the x axis] will give us the roots or zeroes of the polynomials. The degree of a cubic polynomial is [3], therefore the number of zeroes of this cubic polynomial will be 3. Refer to the graph attached, it can be seen that the graph cuts the x-axis at three points -

x = -2, 0, 4

Which are the roots of this cubic polynomial 6x³ - 12x² - 48x  = 0.

Therefore, the roots of the cubic polynomial 6x³ - 12x² - 48x  = 0 are  -2, 0 and 4.

Answer:

The shape of the cross-section is a square

Step-by-step explanation:

Given

[tex]r =2[/tex]

[tex]h = 4[/tex]

See attachment

Required

The shape of the cross-section

From the attachment, we can see that when the cylinder is cut vertically, the shape formed is a quadrilateral of equal opposite sides.

The dimension of the shape is: the height of the cylinder and the diameter of the base circle

From the given parameters, we have the radius and the height to be:

[tex]r =2[/tex]

[tex]h = 4[/tex]

The diameter (d) is:

[tex]d = 2 * r[/tex]

[tex]d = 2 * 2[/tex]

[tex]d = 4[/tex]

So, the dimension is:

[tex]h = 4[/tex] and [tex]d = 4[/tex]

Since the height and the diameter have the same lengths, then the shape is a square.

Step-by-step explanation:

Answer:

In this question one has to look forward to the information's already given. Based on those given information's the answer to the question can be easily determined.

Principal amount = $4000

Time for which money is borrowed = 5 years

Rate of interest = 6%

Then

Amount of Interest = Principal * Rate * Time

                              = 4000 * 6% * 5

                              = 4000 * 6/100 * 5

                              = 40 * 30

                              = 1200 dollars

So the amount of interest that needs to be given is 1200 dollars. I hope the naswer and the procedure is clear enough for you to understand.
