Answer:
The domain is the interval (-∞,∞)
The range is the interval [-4,∞)
Step-by-step explanation:
we have
This is the equation of a vertical parabola in vertex form
The vertex is the point (-4,-4)
The parabola open upward (because the leading coefficient is positive)
The vertex represent a minimum
The domain is the interval (-∞,∞)
so
The domain is all real numbers
The range is the interval [-4,∞)
so
The range is all real numbers greater than or equal to -4
Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
Answer:
Step-by-step explanation:
1/3 + a = 5/4
-1/3 -1/3
<u>a = 4/1 </u>
We can write this expression as 10 - 4 = 9 - x
10 - 4 = 9 - x
6 = 9 - x
6 - 9 = 9 - x - 9
-3 = -x
-3/-1 = -x/-1
3 = x
Hope This Helped! Good Luck!
If it were 100 it would be $20, so for 1000 you just add one more zero and it’s $200
