Answer:
Step-by-step explanation:
30t - 5t² = 10
5t² - 30t + 10 = 0
t = [30 ± √(30² - 4 ⋅ 5 ⋅ 10)] / [2 ⋅ 5]
= [30 ± √700] / 10
= [30 ± 10√7] / 10
= 3 ± √7
≈ 0.35 seconds and 5.65 seconds
Answer:
the expression is equal to -27
whichever expression equals -27 is the answer
Step-by-step explanation:
Answer:
x² + 10x - 24
Step-by-step explanation:
Given the roots are x = - 12 and x = 2 then the corresponding factors are
(x + 12) and (x - 2) and their product equals zero , that is
(x + 12)(x - 2) = 0 ← expand using FOIL
X² + 10X - 24 = 0
Let's check every choices until one choices satisfy the graph :
Choice A is just a translation of -5 units or 5 units to the left
If we look at the graph between A"B"C" and A'B'C'
A"B"C" is 5 units to the left of A'B'C'
Therefore Choice A is True!
The correct answer is A.
No need to check for the other choices since you got a true statement at the first Choice.
IF in case that A is False, then you need to check the other choices.
.no lo sé, pero como necesito puntos, ¿sí?
