If a cubic polynomial has zeros at x= -4, x=0 and x=7, then


A). The polynomial has no imaginary zeros.

B). The polynomial as a pair of imaginary zeros.

Answers

Answer 1
I think the answer ia A that what i think
Answer 2

Answer:

A

Step-by-step explanation:

The Fundamental theorem of algebra tells us that a polynomial of degree n has n roots.

Here the polynomial is a cubic, that is of degree 3

Thus it will have 3 roots, real and/ or imaginary.

Since imaginary roots occur in conjugate pairs

Since the polynomial has 3 real roots there are no imaginary roots, thus

A is the required response.

Two ships leave the same port. Ship A travels at a constant speed of 30 km/h. Ship B travels at a constant speed of 37 km/h. The angle between their paths 62 degrees. How far apart are the two ships from eachother three hours later?

Answers

Answer:

The distance between them is 105.07 km

Step-by-step explanation:

First we need to find the distance travelled by each ship.

To find this distance, we should use the formula:

distance = speed * time

For ship A, we have:

distance1 = 30 * 3 = 90 km

For ship B, we have:

distance2 = 37 * 3 = 111 km

Now, to find the distance between the ships, we can use the law of cosines, where a, b and c are the respectively the distance travelled by ship A, the distance travelled by ship B and the distance between them:

c^2 = a^2 + b^2 - 2*a*b*cos(62)

c^2 = 90^2 + 111^2 - 2*90*111*0.4695

c^2 = 11040.39

c = 105.07 km

The distance between them is 105.07 km

Answer:

(8.47,0) (-0.47,0)

Step-by-step explanation:

y = a(x - h)² + k

y = a(x - 4)² - 20

-4 = a(0 - 4)² - 20

16 = 16a

a = 1

y = (x - 4)² - 20

x-intercepts: y = 0

(x - 4)² = 20

x - 4 = +/- 4.47..

x = 4.47+4, -4.47+4

x = 8.47, -0.47

Answers

Answer:

"As one gets larger, the other gets smaller. So if x = 3, then y = 4218.8, which is under half the original value."

Step-by-step explanation:

In order to complete the sentence we must find the value of "y" when x = 3. We have:

y = 10000*(0.75)^3

y = 4218.8

The sentence then is:

"As one gets larger, the other gets smaller. So if x = 3, then y = 4218.8, which is under half the original value."

Marcus builds kites for a 14 day summer kite festival he plans to give away about the same number of kites each day he gives away 492 kites the first two days did Marcus stick to his plan?

Answers

Answer:

He did not stick to plan; he does not have enough kites.

Step-by-step explanation:

A key information is missing from the question, the number of kites that Marcus made.

After a quick web search, I have found that, in this problem, Marcus has built 2,744 kites in total.

It is know that he gave away 492 kites in the first two days, in a 14 day festival, there are 7 two-day periods. The number of kites required for Marcus to keep that same rate throughout the whole festival is:

[tex]n=\frac{14}{2}=7 \\K=7*492\\K=3,444\ kites[/tex]

Therefore, Marcus did not stick to his plan since he would have needed 3,444 kites to give kites away at the same rate as he did for the first couple days. This could also be interpreted as Marcus giving away too many kites in the first couple days.

The area of grandiose rectangular painting is 56 in.² the width of the painting is 7 inches what is the diagonal of the painting

Answer:

The diagonal of the rectangular painting is  [tex]z = 10.63 \ m[/tex]

Step-by-step explanation:

The diagram for this question is shown on the first uploaded image

From the question we are told that  

    The area is [tex]A = 56 \ in^2[/tex]

    The width of the painting is [tex]w = 7 \ in[/tex]

     

Generally the area of the rectangle is mathematically represented as

          [tex]A = l * w[/tex]

where [tex]l[/tex] the length which is mathematically evaluated as

          [tex]l = \frac{A}{w}[/tex]

substituting value  

         [tex]l = \frac{56}{7}[/tex]

          [tex]l = 8 \ in[/tex]

According Pythagoras theorem

     [tex]z ^ 2 = l^2 +w^2[/tex]

Where z is the diagonal of the rectangular painting

  Now substituting values

      [tex]z = \sqrt{7^2 + 8^2}[/tex]

      [tex]z = 10.63 \ m[/tex]

What is the measure of \angle B∠Bangle, B?
^\circ

degrees

Answers

Answer:Angle B is 44 Degrees

Step-by-step explanation: Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees

The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees

The angles of triangle ABC must add up to 180 degrees

m∠A+m∠B+m∠C=180

46+m∠B+90=180

m∠B+136=180

m∠B=44

The measure of Angle B in the given diagram is 44 Degrees

Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees

The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees

What is the sum of the angles in a triangle?

The angles of triangle ABC must add up to 180 degrees.

m∠B+136=180

m∠B=44

Therefore, The measure of Angle B in the given diagram is 44 Degrees.

Your goal is to design a new shape for a cereal container that will hold the same volume of cereal as a standard ceareal box and costs as little as possible to make. Assume that cardboard costs $0.05 per square inch. How cheaply can you package cereal?

These figures are available.
* triangular prism
* rectangular prism
* cube
* pyramid
* cone
* cylinder
* sphere

You need to keep the volume the same as the original, the surface area has to be less, and the price has to be the cheapest. The original volume was 192in^3. The surface area was 272in^2.

Answers

Answer:

$14.50

Step-by-step explanation:

To calculate the cost for manufacturing a standard cereal box, we must take in account its surface area. The volume will be used to estimate the amount of cereal, the box can contain. The box is a cuboid as standard cereal boxes are cuboid.

So, we will consider the surface area. Given are:

Length- 8 inches

Width- 3 inches

Height- 11 inches

We will find the surface area as : 2lw + 2wh +2lh

= (2x8x3) + (2x3x11) + (2x8x11)

= 48 + 66 + 176 = 290 square inches

Given is - the cost of manufacturing the box is $0.05 per square inch.

So, cost of manufacturing the box with 290 square inches area =

0.05 x 290 = $14.50

The answer is $14.50
