Answer:
5 seconds
Step-by-step explanation:
In 5 seconds it will be at 98 meters
x = -b/2a
x = -20/2(-2) = -20/-4 = 5
In this problem, represents the sea level. Since Dominic is feet below the surface (sea level), his current location is at feet.
The same concept can be applied to Karen, who is at feet.
We need to find who is lower, or farther below . This means the answer is .
A
I think it's A because it mostly multiplies then adds and subtracts so you get your answer doing this
Function: y = 2x²-5
<u>Find y-intercept:</u>
y = 2(0)²-5
y = -5
<u>Find x-intercept:</u>
2x²-5 = 0
2x² = 5
x² = 2.5
x = ±√2.5
x = -1.5811 , 1.5811
