Find the constant of variation k for the direct variation.


A. k = 2

B. k = –0.5

C. k = –1.5

D. k = –2

Answer: 5

Step-by-step explanation:

use formula a^2 + b^2 = c^2

a^2 + 12^2 = 13^2

a^2 + 144 = 169

       - 144   -144

a^2 = 25

sqrt   sqrt

a = sqrt (25)

a = 5

Answer:

In the triangular prism calculator you can easily find out the volume of that solid. A general formula is volume = length * base_area; the one parameter you always need to have given is the prism length, and there are four ways to calculate the base - triangle area. Our triangular prism calculator has all of them implemented, isn't it awesome?

The specific formulas look as follows:

Length * Triangular base area given triangle base and height

It's this well-known formula mentioned before:

volume = length * 0.5 * b * h

Length * Triangular base area given three sides (SSS)

If you know the lengths of all sides, use the Heron's formula to find the area of triangular base:

volume = length * 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )

Length * Triangular base area given two sides and the angle between them (SAS)

You can calculate area of a triangle easily from trigonometry:

volume = length * 0.5 * a * b * sin(γ)

Length * Triangular base area given two angles and a side between them (ASA)

You can calculate that using trigonometry:

volume = = length * a² * sin(β) * sin(γ) / (2 * sin(β + γ))

Answer:

9/16

Step-by-step explanation:

Use the Part = 18, as the numerator and use the Whole = 32, as the denominator. The part-to-whole fraction is 18/32

Meaning:

The Part is 18/32 of the Whole

Reducing the fraction, it is also true that:

The Part = 9/16 of the whole

Answer:

Yes and no solution :)

Step-by-step explanation:

No explanation needed for the first part.

2 as a fraction is 2/1

So rewrite as 2/1 + 2/1

We can multiply the whole equation by lets say.... 428

Now we have 856/428 + 856/428

Now we can put 0 at the other side of the equation... because... yes

856/428+856/428 = 0

Now lets just move one of these to the other side of the equation :)

856/428 = -856/428

Now I dont know, how about we cancel out the denominators.

856=-856

now if we move the right side back to the left... we get

1712=0

This equation is not true therefor 2+2 has no solution

Answer:

A = 216.314

C = 52.124

Step-by-step explanation:

We know the radius so now we need to know the diameter. So multiple the radius by 2.

R = 8.3

D = 16.6

Let's find the area first

A = 3.14×r²

A = 3.14×68.89

A = 216.314

Now find the circumference

A = 3.14×d

A = 3.14×16.6

A = 52.124

Answer:

x = 3

Step-by-step explanation:

(8x + 4) + (- 11x + 5)

= 8x + 4 - 11x + 5

= 8x - 11x + 5 + 4

= - 3x + 9

- 3x + 9 = 0

- 3x = - 9

x = - 9 ÷ - 3

x = 3

I think the answer is b.

Step-by-step explanation:

I added all of the numbers together to get the total (the denominator). after that I subtracted 4 since that's the number of railroad property and got 7. which mean its 7/11.

Answer:

108

Step-by-step explanation:

f(x) = 12(4 - x), x=-5

=f(-5) = 12(4 - x)

12(4-(-5)

=108

Answer:

f(-5) = -12 The picture has the work.

Answer:

Step-by-step explanation:

Without more input from you, it's hard to find an exact value for b.  However, b may take on a large range of values.  b = 10 and b = -3 (chosen arbitrarily) are acceptable choices.

Take a look at the quadratic formula.  The discriminant is b^2 - 4ac.  There is nothing about this equation that restricts or forbids the use of any value of b.

Answer:

Reduction

Step-by-step explanation:

Whenever you see a shape graphed where the points have ' after the letter, then that is the RESULT. So, the yellow parallelogram ABCD is the original, and the blue parallelogram A'B'C'D' is the result, which is obviously smaller than the original. So that means that it's a reduction.

I hope this made sense and helped! :)

Answer:

Step-by-step explanation:

The yellow rectangle is an enlargement of the blue one, and is a positive dilation.  The blue rectangle is shrunken from the yellow one and is a negative dilation.

Answer:

No choices, but 3(2x) is simplified to 6x

Step-by-step explanation:

3(2x) = 3 × 2x = 6x

Answer: The expression that is equivalent to (2x)3 is 6

Step-by-step explanation: The answer is 6 because x is equal to 3 so 3*2=6

Answer:

two unequal real roots

Step-by-step explanation:

35 - 5(4)(-3) simplifies to 35 + 60, or 95.

Because the discriminant is positive, the quadratic has two unequal real roots.

Answer:

This is not a right triangle(No)

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

If you use Pythagorean Theorem, you can determine whether or not these measurements make a right triangle. The hypotanuse is always the longest side, or c, in this equation.

a^2+b^2=c^2

14^2+23^2=25^2

196+529=625

725=625

Obviously, this set of measurements do not make a right triangle. Hope this helped!

Answer:

male= 1/3 brown =1/2, both 1/6

Step-by-step explanation:

there is 2 males and 6 total, simplified is 1/3. there are 3 browns and 3 whites, so simplified is 1/2 instead of 3/6. There is only one brown male, so you cannot simplify it more than 1/6.

We are assuming that only one puppy is given away!

Step-by-step explanation:

6 puppies in total

4/6 are female 2/6 are male

2/6 female and brown 2/6 female and white 1/6 male and brown 1/6 male and white

We want all of the male population which is 2/6 and the 2/6 of the female population that are brown added together
