Answer:
t = 9.58 s
Step-by-step explanation:
Given that,
The height from where the cell phone is dropped, h = 450 feet
We need to find the time for the cell phone to reach the ground. Let the time be t. Using second equation of kinematics to find it.
u is initial velocity, u = 0
a = g
So,
So, it will take 9.58 seconds to reach the ground.
The answer is c! hope this helped!
Answer:
a) 7 numbers in term of n = n+1, n+2, n+3, n+4, n+5, n+6 and n+7
b) n+1+n+2+n+3+n+4+n+5+n+6+ n+7
= 7n+28

Here, we need to find out what is the length of the rectangle. To do this, we'll divide 800 by 25: 800/25 = 32
So we now know that the length is 32 m and the width is 25 m. So we can now find the perimeter:
(32 + 32) + (25 + 25) =
64 + 50 = 114
The perimeter is 114 m. To find how much is will cost to fence 114 meters, we'll multiply the number of meters by the cost per meter: 114 * $12 = $1368
It will cost $1368.
ANSWER
c. Domain: [0,18]
Range: [0,360]
EXPLANATION
The domain refers to the values of x for which the function is defined.
The given straight line graph is defined for x=0 to x=18.
Hence the domain is [0,18]
The range refers to the values of y for which x is defined.
The graph is defined for y=0 to y=360.
The range is [0,360]
