Answer:

390625

Step-by-step explanation:

The questions are all independent -- the answer on one question does not limit the number of possible answers on another question.

The quiz has 5 choices for each question, so there are

5\times5\times5\times5\times5\times5\times5\times5 ways to answer the quiz questions.

Notice that this could be written 5^8.  You could say that the number of ways to answer the questions is

number \, of \, choices^{number \, of \, questions}

Use a calculator to find 5^8

How to turn this equation: <br> y= -1.02(x-3)^2+9.25<br> into factored form
MatroZZZ [7]

Answer:

y=(102x-306-5\sqrt{3774})(102x-306+5\sqrt{3774})

Step-by-step explanation:

You first equate it to zero to get:

-1.02(x-3)^2+9.25=0

Then solve using square root method

-1.02(x-3)^2=-9.25

(x-3)^2=\frac{-9.25}{-1.02}

(x-3)^2=\frac{925}{102}

x=3\pm\sqrt{\frac{925}{102}}

Or

x=3\pm{\frac{5\sqrt{3774}}{102}}

x={\frac{306\pm5\sqrt{3774}}{102}}

Now work it backwards

102x-(306\pm5\sqrt{3774})=0

(102x-306-5\sqrt{3774})(102x-306+5\sqrt{3774})=0

Hence the factored form is:

y=(102x-306-5\sqrt{3774})(102x-306+5\sqrt{3774})

SOLVE FOR M <br><br> −4m+7=−5
Masteriza [31]

Answer:

m=3

-4m+7= -5

Combine like terms.Put +7 on other side.

-4m= -5-7

-4m= -12

It's -4 times m = -12 right ?

So the answer is m=3 because m= -12/-4

5 equivalent fractions of 4/8​
qwelly [4]

Answer:

2/4 1/2 5/10 6/12 10/20

Step-by-step explanation:

just pick an even denominator and take half of that number for the numerator. This only works because the most basic form of 4/8 is 1/2. This method only works if your selected fraction is equivalent to 1/2.
