B. Because of the slope and where it the lines intersect the y axis
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
Answer: QE = 10
Step-by-step explanation: To solve this problem, it's important to understand that the diagonals of a parallelogram bisect each other.
This means that E is the midpoint of diagonal SQ.
So we can setup the equation x² + 9x = 4x + 6.
To solve this polynomial equation, set it equal to zero first.
So we have x² + 5x - 6 = 0 and we get (x + 6)(x - 1) = 0
when we factor the left side of the equation.
So this means that x = -6 or x = 1.
However, -6 will give us a negative length when we plug it in
to find QE so this will not work.
However, plugging 1 in will give us 10 as a length so QE = 10.
Answer:
I'm pretty sure it's the 8 feet deep hole
Step-by-step explanation:
You're earning 8 dollars so that can't be negative.
Temperature can be negative but it doesn't have the - in front of it.
It would be a confusing question if that's the answer because then you'd be basically guessing at it.
I don't think it's the throw because you can't actually throw in negative/throw backwards for it to be negative.
8 feet hole is the only one that makes sense, since you're going down
No, 1.888 is a rational number.
