Answer:

  (d)  x = 3  or  x = 4

Step-by-step explanation:

The zero product property can be used to find the solutions to a polynomial equation when it is written in factored form.

__

Your polynomial can be put in factored form like this:

  x² +12 = 7x . . . . . given

  x² -7x +12 = 0 . . . . . standard form

  (x -3)(x -4) = 0 . . . . . factored form*

  x = 3  or  x = 4 . . . . . . values of x that make the factors zero

_____

* The constants in the binomial factors must have a sum of -7 and a product of +12. It is often convenient to find them by listing factor pairs of 12:

  12 = (-1)(-12) = (-2)(-6) = (-3)(-4)

Negative factors are used because we know the sum must be negative. Both have the same sign so their product is positive. The sums of the pairs shown are -13, -8, -7. The last pair is what we're looking for.

The location final image from the mirror, which is made when an object is placed 1.00 m to the left of the lens, is 0.58 right to the mirror.

The focal length of the lens is the length of the distance between the middle of the lens to the focal point.

It can be find out using the following formula as,

[tex]-\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}[/tex]

Here, (v)is the distance of the image, (u) is the distance of the object, and (f) is the focal length of the lens.

The lens and mirror in the Figure are separated by 1.00 m and have focal lengths of +79.2 cm and -50.6 cm, respectively. Change the units of focal length in meters,

[tex]f_l=79.2\text{ cm=0.792 m}\\f_m=-50.6\text{ cm=0.506 m}[/tex]

An object is placed 1.00 m to the left of the lens. Put the value in the lens formula as,

[tex]-\dfrac{1}{v_l}+\dfrac{1}{1}=\dfrac{1}{0.792}\\-\dfrac{1}{v_l}=\dfrac{1}{0.792}-1\\v_1=3.81[/tex]

The distance of the image made by lens is 3.81 meters. The distance of this image from the mirror is,

[tex]u_2=3.81-1\\u_2=2.81\rm \; m[/tex]

This distance is work as object distance for the mirror. The focal length of mirror is -0.506 m. Thus, the location of the final image is,

[tex]-\dfrac{1}{v_2}+\dfrac{1}{3.81}=\dfrac{1}{-0.506}\\\dfrac{1}{v_2}=-\dfrac{1}{3.81}-(-\dfrac{1}{0.506})\\v_2=-0.58[/tex]

Thus, the location final image from the mirror which is made when an object is placed 1.00 m to the left of the lens, is 0.58 right to the mirror.

Answer:

90%

Step-by-step explanation:

We know that 9 of 10 people were less than 65. It means, that if they would ask 100 people, the number would be 90.

The percent of population less than 65 is 90%

Ninety percent of the population was less than 65.

The percentage is defined as the ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

According to data from the U.S. Census Bureau,

Approximately 9/10 of the U.S population was less than 65 years old.

Nine out of ten people, as far as we know, were under 65.

In other words, if they surveyed 100 persons, the answer would be 90.

Hence, Ninety percent of the population was less than 65.

The statement is true is: A 16,000-BTU air conditioner meets the manufacturer recommendation.

Option A

BTUs=16,000/(20 feet×20 feet×8 foot)

BTUs=16,000/3200 feet

BTUs=5 BTUs

Option B

BTUs=14,000/(10 feet×20 feet×8 foot)

BTUs=14,000/1600 feet

BTUs=8.75 BTUs

Option C

BTUs=20,000/(20 feet×40 feet×8 foot)

BTUs=20,000/6400 feet

BTUs=3.125 BTUs

Option D

1: [tex]3n^{2}+9n+6[/tex]

notice that each part is divisible by 3

[tex]3n^{2}[/tex] ÷ 3 = [tex]n^{2}[/tex]

9n ÷ 3 = 3n

6 ÷ 3 = 2

so it becomes [tex]3(n^{2} +3n+2)[/tex]

3n can be rewritten as 2n+n

-you want to rewrite it into two numbers that multiply to the number that's alone (in this case 2)

which would get you

[tex]3(n^{2} +2n+n+2)[/tex]

Now that it's rewritten, you can factor out n + 2 from the equation.

the answer is

3(n+2)(n+1)

And you can check that by multiplying (n+2)(n+1) which is [tex]n^{2} +2n+n+2[/tex] and then each of those by 3, which is [tex]3n^{2} +6n+3n+6[/tex] or [tex]3n^{2}+9n+6[/tex], our origional equation

2: [tex]28+x^{2} -11x[/tex]

So I rewrote this as [tex]x^{2} -11x+28[/tex] (it's the same thing, just reordered using the commutative property)

now -11x can be rewritten as -4x-7x

(remember, the two numbers should multiply to equal 28, which is our constant.)

[tex]x^{2} -4x-7x+28[/tex]

now we can factor out x from the first expression and -7 from the second

[tex]x(x-4)-7(x-4)[/tex]

and lastly you factor out x-4,

which would give you

(x-4)(x-7)

Make sure to check your work and make sure it multiplies to [tex]x^{2} -11x+28[/tex]

3: [tex]9x^{2} -12x+4[/tex]

The first thing I notice when looking at this problem is that both 9 and 4 are perfect squares. Not only that, but they are the squares of 2 and 3, which are products of -12

So if you rewrite 9 as [tex]3^{2}[/tex] and 4 as [tex]2^{2}[/tex], the equation becomes

[tex]3^{2} x^{2} -12x+2^{2}[/tex]

now that [tex]3^{2} x^{2}[/tex] is ugly so it can be turned into [tex](3x)^{2}[/tex]

and -12x can be rewritten as [tex]-2*3x*2[/tex]

so our equation now looks like [tex](3x)^2-2*3x*2+2^{2}[/tex]

There's a rule that says [tex]a^{2} -2ab+b^{2} = (a-b)^{2}[/tex]

In our case, a=3x and b=2

so the final answer is

[tex](3x-2)^2[/tex]

Using the conversion of exponent to power, the equivalent expression is given as follows:

[tex]a^{\frac{n}{m}} = \sqrt[m]{a^n}[/tex]

In this problem, we are given the following expression:

[tex]x^{\frac{1}{2}}y^{-\frac{1}{4}}z^{-2}[/tex]

Negative exponents go to the denominator, hence the equivalent expression is given by:

arc = 9π units

Step-by-step explanation:

the arc is half the circumference of the circle, then

arc = [tex]\frac{1}{2}[/tex] × 2πr = πr , then

arc = π × 9 = 9π

Answer:

[tex]\boxed{\tt 9\pi }[/tex]

Step-by-step explanation:

What we want to find here is the arc length of 1/2 of a circle, we'll start by finding the of the circle.

[tex]\tt 2\pi \times 9[/tex]

[tex]\tt 9\times 2\pi[/tex]

[tex]=\tt 18\pi[/tex]

Step 2:- find the arc length of 1/2 of the circle →

The arc length is 1/2 of the circumference of the circle:-

[tex]\boxed{\sf Circumference \; of \;\cfrac{1}{2}\; of\; the \; circle=\cfrac{1}{2}\times 18\pi}[/tex]

[tex]\tt \cfrac{18}{2} \pi[/tex]

6 pint / 2 = 3 quarts

12 / 2 = 6 quarts

8 x 2 = 16 pints

In order to order the measurement, all the measurements have to be in the same units. All the units would be converted to cups

1 quart = 4 cups

4 x 6 = 24 cups

Step-by-step explanation:

The area of a parallelogram is base • height.

So:

1. Calculate the area of what you can get for $50. 5 • 212 = 1060 square meters.

2. Now you divide the first price ($50) by the desired price ($1). This one is easy because 50 / 1 = 50, but I'm putting this here for future reference in case you need to solve a problem that has a desired price that's greater than $1.

3. Divide the answer to step one by the answer to step two to get the area you can have painted for $1. 1060 / 50 = 21.2 square meters.
