Answer:
n > 3
Step-by-step explanation:
isolate n on the left side by subtracting 8 from both sides
n > 3
Answer:
D
Step-by-step explanation:
lx+2l+7>10 /-7
lx+2l>3
if x >0, x+2>3 /-2, x>1
if x <0, x+2<-3 /-2, x<-5
Answer:
SEE BELOW IN BOLD.
Step-by-step explanation:
a.
h = -16t^2 + 50t
h = 20 t
When the height is the same:
-16t^2 + 50t = 20t
-16t^2 + 30t = 0
t(-16t + 30) = 0
t = 0 or -16t + 30 = 0, so:
t = 0 or -30/-16 = 1.875
So the answer is 1.88 seconds to the nearest hundredth.
b.
For the ball
h = -16t^2 + 50t
Finding the derivative and equating to zero:
dh/dt = -32t + 50 = 0
t = -50/-32 = 1.563
Maximum height after 1.56 seconds to nearest hundredth
c.
When the ball hits the ground h = 0 so
-16t^2 + 50t = 0
-16t(t - 50/16)= 0
T = 3.13 SECONDS TO THE NEAREST HUNDERDTH
Answer:
2x^2-2x
Step by Step Explanation:
The 2 x^2 come together to form 2x^2 and since there is no other number that has x but no ^2 -2x stays the same.
In this problem your going to need to find volume.
The formula for volume of a rectangular prism (Which is what we are trying to find)
Is Volume = Length x Height x Width
So in your problem we can create the equation:
7 x 4 x 12 = Your answer.
7 x 4 = 28
28 x 12 = 336.
Your going to need 336 feet^3 (D)
Hope this helps!
