Answer:
The skydiver will fall 1600 ft in 10 seconds.
Step-by-step explanation:
<u>Distance a body falls from rest varies directly as the squares of the time it falls </u>
Let distance = s
time = t
Therefore , s = k
Given, the body falls 64 ft in 2 seconds.
Substituting in above equation,
64 = k
64 = k
k =
k = 16 ft/
We have to find how much he will fall in 10 seconds.
s = k
s =
s =
s = 1600 ft

Answer:
12 and 10 and
-12 and - 10
Step-by-step explanation:
Givens
Larger number = x
Smaller number = x - 2
Equation
x*(x - 2) = 120
Solution
Remove the brackets
x^2 - 2x = 120
Subtract 120 from both sides
x^2 - 2x - 120 = 0 Factor
(x - 12)(x + 10) = 0
x - 12 = 0
x - 12 + 12 = 12
the other number is 2 less than this one or x = 10
=================
x + 10 = 0
x = - 10
The number that is 2 less than this one is
x = -10 -2
x = -12
The answer would be $60
i hope this helpssss
Step-by-step explanation:
a) 4 , 7 , 10 , . . . . .
Here we can see that ,
- Common difference = 10-7 = 3
- First term = 4.
We know the formula of nth term as ,
Sum of 20 terms as ,
b) -15 , -8 , -1 . . . . .
Here we can see that ,
- Common difference = -8+15 = 7.
- First term = (-15).
We know the formula of nth term as ,
Sum of 20 terms as ,
