A square has a side of length 12. Find the length of one diagonal.

Answer:

[tex]x=\frac{3}{4}[/tex]

Step-by-step explanation:

First, we know we want to get x all by itself. So, let's multiply it by 2.

[tex]\frac{2}{x}(2) = \frac{3}{4}(2)\\[/tex]

Then we have:

[tex]x=\frac{3}{4}(2)[/tex]

Now, we have to simplify the right side of the equation, so, let's rewrite it.

[tex]x=\frac{3*2}{4*2}[/tex]

All we have to do now is simplify.

[tex]x=\frac{6}{8}[/tex]

Luckily (and ironically) both the numerator and denominator are divisible by 2, so...

[tex]x=\frac{3}{4}[/tex]

I hope this helps!

Answer:

C is the correct answer.

Step-by-step explanation:

All of the angles in a triangle add up to 180 degrees. 65+80=145 and when you do 180-145, you get 35 degrees. You can check to see if it's correct by adding 35, 65, and 80 together.

[tex]65+80=145[/tex]

[tex]180-145=35[/tex]

[tex]35+65+80=180[/tex]

The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC. Option C is correct.

What exactly is a triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

ΔDEF

∠F=80°

∠F=35°

The sum of the angle of the triangle DEF is;

∠D+∠E+∠F=180°

∠D=180°-115°

∠D=65°

In ABC

/_A = 65°

/_B= 80°

∠A+∠B+∠C=180°

∠D=180°-145

∠D=35°

The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC.

Hence,option C is correct.

Answer:

-6

Step-by-step explanation:

Sorry, no explaination, but it's correct (trust me)

The value of n for which the considered quadratic equation p(x) and k(x) are such that p(x) = k(x) + n is n = -6

If a quadratic equation is written in the form

[tex]y=a(x-h)^2 + k[/tex]

then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)

This graph goes through three points, (-3,3), (3,3), and (0,-6) (the last point is the vertex of the quadratic equation).

Let the function p(x) be:

[tex]p(x) = a(x-h)^2 + k[/tex]

Since the vertex lies on the point (h,k) = (0,-6), putting h = 0, and k = -6, we get:

[tex]p(x) = ax^2 -6[/tex]

Now, as this graph passes through (x,y) = (-3,3), putting x= -3, and y (output, or say p(x)) = 3, we get:

[tex]3 = a(-3)^2 - 6\\3 = 9a-6\\9a = 9\\a =1[/tex]

Thus,  the function p(x) is:

[tex]p(x) = x^2 - 6[/tex]

But since [tex]k(x) = x^2[/tex], therefore,

[tex]p(x) = x^2 - 6 = k(x) - 6[/tex]

On comparison with p(x) = k(x) + n, we deduce that n = -6

Thus, the value of n for which the considered quadratic equation p(x) and k(x) are such that p(x) = k(x) + n is n = -6

Answer:

9 different car washes

Step-by-step explanation:

From the services that Jorge offers we can see that there are 3 options (wax, vacuum, and interior cleanings) on 3 different categories of vehicles (cars, trucks, and SUV). Therefore, in order to calculate the number of possible combinations or car washes that you can make, we need to multiply the number of options by the number of categories of vehicles. Like so...

3 * 3 = 9

Therefore, we can see that there are a total of 9 different car washes that you can make for the weekend.

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr²[tex]\frac{h}{3}[/tex]

We know the radius = 12

and the height = 8

Substitute :

V = π12²[tex]\frac{8}{3}[/tex]

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = [tex]\frac{2^4*3^2*8\pi }{3}[/tex]

Cancel the common factor - 3 :

V = [tex]2^4 * 8 * 3\pi[/tex]

Multiply 8 and 3π :

V = [tex]2^4 * 24\pi[/tex]

Solve the exponent :

V = [tex]16 * 24\pi[/tex]

Multiply :

V = [tex]384\pi[/tex]

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³
