8 0

Answer:

there are 720 possible answers

Step-by-step explanation:

(10 choices) on the first, then the second (9 choices) then the third (8 choices). So there would be 10 x 9 x 8 = 720 possible choices.

Answer:

720

Step-by-step explanation:

If order mattered, we would say select the first number (10 choices), then the second (9 choices) then the third (8 choices). So there would be 10 x 9 x 8 = 720 possible choices.

Reginald answered at 78% of the questions on his social studies quiz correctly what fractional part of the question did he not a

Otrada [13]

If Reginald answered 78% correctly out of a total 100%, we can subtract 78 from 100:

100 - 78 = 22

He answered 22% of the question incorrectly. But how do we find the bottom number? Remember what we said earlier. The total is 100%. He got 22% out of 100% wrong. Wouldn't that be $\frac{22}{100}$ ?

Now that we know our fraction, we can reduce it. Let's start by dividing our fraction in half:

$\frac{22}{100}$ = $\frac{11}{50}$

Can we reduce that any more? No, because 11 can not be divided by anything else.

If you want the first fraction, go with $\frac{22}{100}$ , but if they want a reduced fraction, then $\frac{11}{50}$ would be best.

Answer:

f(x) = (x +4)(x -1)(x -2)²

Step-by-step explanation:

The given points are all x-intercepts of the function. As such, each corresponds to a factor of the function. The x-intercept x=p corresponds to factor (x-p), for example.

Here, the x-intercept (2, 0) is repeated. It is said to have "multiplicity 2". That multiplicity value means the factor will have an exponent of 2 in the factored form of the function:

f(x) = (x -(-4))(x -2)(x -1)(x -2)

f(x) = (x +4)(x -1)(x -2)²

_____

Additional comment

When an x-intercept has even multiplicity, the graph will touch the axis there, but will not cross.

Answer:

see below

Step-by-step explanation:

I will be using pythagorean triples for some, but you can use sqrt(a^2+b^2)=c^2

1. 12 13 5 x=5

2. 3 4 5 x=5

3. sqrt(14.7^2-11.9^2)=sqrt(74.48) or around 9 (root is irrational)

4. sqrt(15.4^2-6.3^2)=sqrt(197.47) or around 14 (same thing)

5. sqrt(15^2-11^2)=2*sqrt(26) or around 10

6. sqrt(4^2-sqrt(6)^2)=sqrt(16-6)=sqrt(10) or around 3

7. sqrt(12^2+9^2)= 15, so it is a right triangle

8. 9, 12, 15 divide by 3- 3, 4, 5 pythagorean triple - is a right triangle

9. 9, 12, 15-17>15, obtuse

10. sqrt(20.1^2+18^2)=20.4 - 20.1<20.4, acute

11. sqrt(4.8^2+28.6^2)=29, 29=29, right
