Answer:
6 seconds
Step-by-step explanation:
h(x)=-(x-2)^2+16
We want h(x) to be 0 ( that is when the ball hits the ground)
0 = -(x-2)^2+16
Subtract 16 from each side
-16 = -(x-2)^2+16-16
-16 = -(x-2)^2
Divide by -1
16 = (x-2)^2
Take the square root of each side
sqrt(16) = sqrt((x-2)^2)
±4 = x-2
Add 2 to each side
2±4 = x-2+2
2±4 =x
2+4 = x 2-4 = x
6 =x -2 =x
Time cannot be negative so x=6
Answer:
5m^5-m^3-3
Step-by-step explanation:
What you do is you have to distribute the negative sign into the equation.
-m^5-2m^3+4m-6. Next, you will either add or subtract from the other equation.
6m^5-m^5=5m^5.
m^3-2m^3=-m^3.
-4m+4m=0m or you don't put anything.
3-6=-3. Then you put it all together to get.
5m^5-m^3-3 as your answer.
are of a circle=pie r squared. So first find the area using the diameter. half of 3.5 is 1.75. 1.75 squared is 3. 06. 3.14 times 3.06 is 9.61. Now find half of that which is 4.81
