what polynomial could you add to 3x^4 - 9x^3 + 5x^2 - x + 7 to get a sum of 3+4x^4 + 3x-x^3 + 3x^2

Answers

Answer 1

x^4 + 8x^3 - 2x^2 - 4x - 4. I just thought of it like the second polynomial plus the polynomial you need to solve for equals the first polynomial.

Three highways connect the centers of three towns and form a triangle. A cell phone company wants to place a new cell tower so that it is the same distance from the centers of the three towns. How can the company find where to place the tower? Explain.Three highways connect the centers of three towns and form a triangle. A cell phone company wants to place a new cell tower so that it is the same distance from the centers of the three towns. How can the company find where to place the tower? Explain.

Answers

The company can find where to place the tower by determining the point of concurrency of these three (3) towns.

What is a triangle?

A triangle refers to a two-dimensional shape that is typically made up of three (3) sides, three (3) vertices and three (3) angles. This ultimately implies that, a polygon that has three (3) lengths of sides is a triangle.

What is a point of concurrency?

A point of concurrency can be defined as a single point that is shared by three (3) or more lines, segments, rays, or planes. Thus, a triangle is considered to be concurrent when at least three (3) lines intersect at a single point.

Based on geometry, the point (circumcenter) that is equidistant from the vertices of the triangular tower would be equal in distance from each of the centers of these three (3) towns.

Generally, the circumcenter of a triangle can easily be determined by constructing the point of concurrency of the perpendicular bisectors of a triangle.

In conclusion, the company can find where to place the tower by determining the point of concurrency of these three (3) towns, so that they all have the same distance from the centers.

Read more on point of concurrency here: https://brainly.com/question/11844452

Answer:

For the tower to be the same distance from each of the centers, the company must find the point that is equidistant from the vertices of the triangle. This is the circumcenter of the triangle and can be found by constructing the point of concurrency of the perpendicular bisectors of the triangle.

The tower needs to be equidistant from the vertices of the triangle.

The tower should be placed at the circumcenter of the triangle.

To find the circumcenter, find the intersection point of the three perpendicular bisectors of the triangle.

Match the solution set of each of the following inequalities with its graph.

Answers

The following inequalities with its graph are:

For graph 1: x≤-2,

For graph 2: x≥2,

For graph 3: x≥2,

For graph 4: -2<x

For graph 5: x<2

Inequality is defined as a relationship between two expressions or values that are not equal to each other.

A number line is a representation of real numbers in the form of a graduated straight line.

The solution for the first graph is x less than or equal to -2.

1. x≤-2

The solution to the second graph is x higher than or equal to 2

x≥2

In the third graph, the solution x is greater than or equal to 2

As a result, the inequalities for the respective graphs are x-2, x2, x2, -2x, and x2.

Could 3.2, 10.7, and 5.5 be the side lengths of a triangle?

Answers

no because the 2 shorter sides has to be more than the longer side

No, for any triangle with sides a,b, and c, a+b>c

Here 3.2+5.5=8.7

And 8.7<10.7, so this could not be a triangle.

The length of a rectangle is 4 inches more than its width. The area of the rectangle is equal to 4 inches less than 5 times the perimeter. Find the length and width of the rectangle.

Answers

Solution:
Let the width of the rectsngle (b) be x
and the length of the rectangle (l) =x+4
Area of the rectangle (A)=?
Perimeter of the rectangle (P)=?
Now,
P= 2 (l+b)
= 2 (x+4+x)
= 2 (2x+4)
= 4x+8
And,
A= l×b
= x(x+4)
= x^2+4x
According to the question,
A=5P-4
or, x^2+4x =5 (4x+8)-4
or, x^2 +4x =20x+40-4
or, x^2 = 20x-4x+36
or, x^2 = 16x+36
or, x^2-16x-36 = 0
or, x^2-(18-2)x-36 = 0
or, x^2-18x+2x-36 = 0
or, x (x-18)+2 (x-18) = 0
or, (x-18) (x+2) = 0

Either, Or,
x-18 = 0 x+2 = 0
so, x = 18 so, x = -2

Taking the value of x = 18 ( Because the length is always positive)
Length = x+4 = 18+4 = 22 cm
Width = x = 18 cm

A packet of sour worms contains four strawberry, four lime, two black currant, two orange sour, and three green apples worms. What is the probability that Dustin will choose a green apple sour worm, P(green apple)?

Answers

When you add all the worms in the bag together, you have a total of 15 worms. There are three green apple flavored sour worms. the ratio of green apple to the total is 3/15. To simplify this ratio further, divide by the common factor of 3. You will get 1/5. The probability that Dustin will pick a green apple worm is 1/5. To convert to percentage , simply divide one by 5. you will get .2, which in percent is 20%. The probability that Dustin will pick a green Apple worm is 1/5 or 20%.

Answers

The slope of the given line y = x – 2 is 1. Therefore, the slope of a line perpendicular to y = x – 2 is -1/1, or just -1.

In point-slope form, the equation of the new line is

y-10 = -1(x-[-12]), or y-1 = -(x+12) or y-1 = -x - 12, or
y = -x - 11.

Jim’s statement is correct for all numbers greater than or equal to 0 and negative integers. It does not work for negative non-integer numbers.

Step-by-step explanation:

Given :

The output of the floor function is the number before the decimal point.

Solution :

Jim’s statement is correct for all numbers greater than or equal to 0 and negative integers. It does not work for negative non-integer numbers.

For example, the floor of –5.5 is –6, the floor of -4.5 is -5 (the number before the decimal point).

For more information, refer the link given below

https://brainly.com/question/13666156?referrer=searchResults

The floor function outputs the number before the decimal point for non-negative real numbers.

Jim's statement is correct for non-negative real numbers.

The floor function rounds down to the nearest integer, which is always the number before the decimal point.

For example, if the input is 3.8, the output will be 3.

If the input is -2.5, the output will be -3.

The weight of an African elephant is 6x10^6 grams; the weight of a tiger is 3x10^5 grams. How many times heavier is the elephant than the tiger?

Answers

so that means
elephant= x times tiger

6 times 10^6=x times 3 times 10^5
divide both sides by (3 times 10^5)
remember that (x^m)/(x^n)=x^(m-n)
so
(6 times 10^6)/(3 times 10^5)=x
(6/3) times (10^6)/(10^5)=x
2 times 10^1=x
2 times 10=x

that would be 2 times 10^1 or 20 times

The answer would be 20 times longer.

Mr. and Mrs. McClurrie are debating on whether or not to remove a tall tree in their front yard. Mr. McClurrie is concerned that the tree could fall during a storm and land on their home. Mrs. McClurrie disagrees. She thinks the tree poses no danger to their home and wants to keep the tree because of the wonderful shade it provides. They decide to estimate the height of the tree using special right triangles.

They stood 25 feet from the base of the tree to create a 30° angle from the ground to the top of the tree.

If their home is 20 feet from the base of the tree, could the McClurrie's wait a few more years before cutting down the tree or does it pose a risk now?

Answers

Check the picture.

Let A be the point where Mr. and Mrs. McClurrie are standing, let B be the base of the tree and C the top of the tree. Let H be the point representing the house.

ABC is a right triangle, with m(BAC)=30°.

so by special triangles, if the length of the hypotenuse is 2x, the length of BC is x, since it is the side opposite to the 30° angle.

by the pythagorean theorem :

[tex](AC)^{2}= (AB)^{2}+(BC)^{2} [/tex]
[tex](2x)^{2}= (25)^{2}+(x)^{2} [/tex]
[tex]4x^{2}= (25)^{2}+x^{2}[/tex]
[tex]3x^{2}= (25)^{2}[/tex]
[tex]x= \sqrt{ \frac{(25)^{2} }{3}}= \frac{25}{ \sqrt{3} }= \frac{25 \sqrt{3} }{3} [/tex]
[tex]\frac{25 \sqrt{3} }{3}=25* \frac{ \sqrt{3} }{3}=25*0.577= 14.43[/tex] (feet)

so even if the tree falls, it falls more than 5 feet away from the house.

Answer: they can wait a few more years.
