Use the long division method to find the result when 4x^3+23x^2 + 21x + 30 is
divided by x +5.

Answers

Answer 1

Answer:

A polynomial is an algebraic expression made up of two or more terms subtracted, added, or multiplied. A polynomial can contain coefficients, variables, exponents, constants, and operators such as addition and subtraction.

It is also important to note that, a polynomial can’t have fractional or negative exponents. Examples of polynomials are; 3y2 + 2x + 5, x3 + 2 x 2 − 9 x – 4, 10 x 3 + 5 x + y, 4x2 – 5x + 7) etc. Like number, polynomials can undergo addition, subtraction, multiplication, and division.

We saw addition, subtraction, multiplication, and long division of polynomials previously.

Answers

Answer:

15, 25

Step-by-step explanation:

Answer:The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. The answer is C.

You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?

Answers

Answer:

$17,276

Step-by-step explanation:

Given data

Time= 5 years

Principal= $14,000

Rate= 4.3%

We want to find the final amount

A=P(1+r)^t

Substitute

A= 14000(1+0.043)^5

A= 14000(1.043)^5

A= 14000*1.234

A=$17276

Hence the total amount is $17,276

Answer:

[tex] m\angle XYZ = 70\degree [/tex]

Step-by-step explanation:

By exterior angle theorem:

4x° = 2x° + 70°

4x° - 2x° = 70°

2 x° = 70°

2x = 70

x = 70/2

x = 35

[tex] m\angle XYZ = 2x\degree [/tex]

[tex] m\angle XYZ = 2\times 35\degree [/tex]

then you multiply 4 by 3 and thats 12 and 3 times 5 is 15 so no they arent perportional

(12,6) (4,4)

Answers

Answer:

I'm sorry that no one is helping you, the correct answers are A and F.

Step-by-step explanation:

The line's equation is [tex]y=\frac{1}{4} +3[/tex]. You know this because the slope of the line is found by subtracting the y-value of the two points and dividing it by the difference of the x-values, which would be [tex]\frac{6-4}{12-4} = \frac{2}{8} = \frac{1}{4}[/tex]. Using the slope, you can calculate the y-intercept of the equation, which you just multiply the slope by the distance to the y-axis and subtract that from the y-value of (4, 4), which you will get [tex]4 + (-4*\frac{1}{4}) = 4+(-1) = 3[/tex]. So the equation of the line is [tex]y=\frac{1}{4} +3[/tex]. When you simplify all the choices below, you'll get that only A and F are equivalent to the equation, so those are the correct choices.

Rachel ran 3 miles when she was training for a race. How many feet did she run?

Answers

Answer:

15,840 i did this in test and got 100%

Step-by-step explanation:

The total feet ran by Rachel is given by the equation A = 15,840 feet

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the total miles ran by Rachel be A = 3 miles

Now , the value of 1 mile = 5,280 feet

Substituting the values in the equation , we get

The distance of 3 miles in feet = 3 x value of 1 mile

On simplifying the equation , we get

The distance of 3 miles in feet = 3 x 5,280

The distance of 3 miles in feet = 15,840 feet

Therefore , the distance ran by Rachel A = 15,840 feet

Hence , the equation is A = 15,840 feet

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

A support wire is attached to the top of an antenna. The support wire connects to the ground 15 feet from the bottom of the antenna.

Let x be the height of the antenna.

We can find the length of the antenna using the trigonometric ratios:

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying tan ratio in the right angle triangle:

tan70 = x/15

x =15tan70

x = 41.212 feet  ≈ 41.23 feet

Thus, the height of the antenna is 41.23 feet if the support wire is attached to the top of the antenna.

To find:

The number of quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

[tex]8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}[/tex]

Therefore, there are 33 quarts in [tex]8\dfrac{1}{4}[/tex] gallons.
