Answer:
у = x² + 7x - 30
Step-by-step explanation:
x₁ = 3 and x₂ = -10
Use the formula (x - x₁)(x - x₂) = 0
(x - 3)(x - (-10)) = 0
(x - 3)(x + 10) = 0
x² + 10x - 3x - 30 = 0
x² + 7x - 30 = 0
If I can remember correctly I think it is C: stocks
Answer:
35/36
Step-by-step explanation:
1) Remove parentheses.
3/4 + 2/9
2)Simplify
= 35/36
If it is 4 1/2, you can make 10 four and a half inch strips with no remainder
If is the distance the runner travels between first and second base, then the distance between him and home plate satisfies
(where the 90 here refers to the distance between first base and home)
Differentiating both sides with respect to time gives
The runner's speed is . When he is away from first base, he is
away from home plate. So he is moving away from home plate at a rate of
