2 answers:

4 0

The answer would be a negative number.
Say we have -3³.
That would be -3 x -3 x -3, which you would end up with -27.
On even exponents with a negative number, You would end up with a positive.

Find angle B. What is angle B.

julsineya [31]

Answer:

B=45 Degrees

Step-by-step explanation:

You can use law of sines to answer. Law of Sines states that $\frac{sin(a)}{A} =\frac{sin(b)}{B}$ . That means that $\frac{sin(60)}{4\sqrt{6} }=\frac{sin(b)}{8}$ . Multiplying 8 to both sides gives us $\frac{8sin(60)}{4\sqrt{6} }=sin(b)$ . By using inverse of sin, we get $b = sin^{-1} (\frac{8sin(60)}{4\sqrt{6} } )$ . Plugging that into a calculator gives us b=45 degrees.

If the Math Olympiad Club consists of 13 students, how many different teams of 5 students can be formed for competitions?

rjkz [21]

Answer:

2 teams

Step-by-step explanation:

13 divided by 5 is 2.6, but you cannot split a person in half, so it would be two teams with a remainder of three people.

Solve for C.<br> 5/4= -4c + 1/4

dybincka [34]

5/4= -4c + 1/4

Inverse operation

$\frac{5}{4} = -4c + \frac{1}{4}$

- 1/4 -1/4

5/4 - 1/4 = 4/4

$\frac{4}{4} = -4c$
-4c/-4 = 4/4 ÷ -4/1

4/4 *- 1/4 = c
-4/8 = c
c = -1/2

Answer: $c = - \frac{1}{2}$

sdas [7]

solution:

$x^{2}+12x-7=0\\add 7 to both side of the equation\\x^{2}-12x=7\\to creat a trinomial square on the left side of the equation.\\find a value that is equal to the square of b and the cofficent of x.\\(\frac{b}{2})^2=(-6)^2\\add the term to each side of the equation\\x^2-12x+(-6)^2=7+(-6)\\x^2-12x+36=43\\(x-6)^2=43\\solve the equation for x.\\$ $take the square root of each side of the equation to the set up the solution x,\\(x-6)^2.\frac{1}{2}=\pm \sqrt{43}\\x-6=\pm \sqrt{43}\\x=6\pm \sqrt{43}$

HELP ME PLEASE!!!!!!! What is the volume of the cube?

tatiyna

The answer is A. 3375 mm^3. This is because, since it is a cube, all of the sides are the same, meaning that you have to do 15 × 15 = 225, and then multiply that by 15 which is 3375. I hope this helps!
