Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.
Answer: 20.25 m
Step-by-step explanation: To find the area of a triangle, use the formula (b•h)/2. Using this formula, substitute the numbers:
(9•4.5)/2
Then solve.
40.5/2
20.25
The answer to your question is option A
Answer:
The present was 300 feet above ground 5 seconds after being thrown.
6.47 seconds passed before the present hit the ground.
Step-by-step explanation:
We have the following quadratic function
Which determines the height of the present.
Determine when the present was 300 feet above the ground.
This is when 
. So
This is 
and 
. There are no negative time instants. So the present was 300 feet above ground 5 seconds after being thrown.
Determine how many seconds passed before the present hit the ground.
This is t when 
6.47 seconds passed before the present hit the ground.
Answer:
50/10=5 so the ratio is 5 times more
there was 6 sheets of red paper and there is 5 times more so 5 x 6 = 30 red sheets
