Answer:
Step-by-step explanation:
Hello, we know that if the equation is
Then the vertex is the the point (h,k)
Here, the vertex is the point (-2,-20) so we can write, a being a real number that we will have to find,
On the other hand, we know that the y-intercept is (0,-12) so we can write
So the equation becomes.
And we can give the standard form as below.
Thank you.
Answer: 1, 3
For a cubic polynomial, there are either 3 real roots or 1 real root nad 2 complex roots in a conjugate pair.
Deep because it has a line above the 4
Each car is traveling 40 miles per hour
So 119 out of 250 people had a pool in their backyard...119/250 = 47.6%
so out of 10,000 people, expected value of ones with a pool is :
47.6% of 10,000 ...
0.476 * 10,000 = 4760 people <===
