Answer: square root of 3/2 seconds
Step-by-step explanation:
h=-16x²+24
Set the height to be 0
0=-16x²+24
-24=-16x²
24=16x²
24/16=x²
x²=3/2
x= square root of 3/2
Answer:
1/0.4=10/4=5/2...............
Answer:
Lori would have to save $5,760
Step-by-step explanation:
Since 320×6=1920, you would have to add to see witch number would be best to save up too. You would get $5,760 when you multiple by 3.If you multiple by 2,it wouldn't give you enough money.
First subtract -19 - 1 = -20
Next, + (-24) is the same as just simply subtracting 24
-20 - 24
Subtract that and you get -44
So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)
