Answer:

the answer is A

Step-by-step explanation:

the reason why is because the car starts at 0mph and as the car increases in speed the line will continue to increase and then the car stays at a constant speed which means the line will not go up or down on the y but will get longer on x because of time. and then the the speed decreases. and the only graph that shows an increase, constant, and decrease is graph A.

To find the mean: You have to add them all together, then divide them by how many numbers there are.
 
So: 23+25+32+35+36+25+27 = 203

How many numbers did we add up? 7.

203 ÷ 7 = 32.85714 (That is the mean rounded up to the nearest hundredth thousandth).

Which two values of x are roots of the polynomial below?
Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}

3. Solve the square root:

x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}

x=\frac{-5+-\sqrt{25-28} }{2(1)}

x=\frac{-5+-\sqrt{-3} }{2(1)}

4. Simplify the rest:

x=\frac{-5+-\sqrt{-3} }{2}

5. Separate the solutions:

x=\frac{-5+\sqrt{-3} }{2}  , x=\frac{-5-\sqrt{-3} }{2}

Thus, options B and C are the answers.

hope this helps!
