Answer: a and b are correct
I am very sure
Step-by-step explanation:
There's always a decimal at the end of a whole number. here it's behind the last zero. move that decimal so that the non-zero digit is less than 10 but more than 1.
4.73, the decimal was moved 4 places to the left. so the scientific notation is
4.72X10^4
Answer:
Step-by-step explanation:
Given
Required
Simplify and present your answer in
First, we need to expand and factorize the numerator:
Express 12 as 10 + 2
Split into two using brackets
Split to two fractions:
Factorize the numerator of the first fraction
The first fraction can be simplified to give:
Hence, by comparison:
We have simplified the given expression to the required format of:
Which implies that:
and
Answer:
80 ft/s
Step-by-step explanation:
Given that,
A ball is thrown vertically upward from the top of a 96-ft tower, with an initial velocity of 16 ft/sec. Its position function is given by :
...(1)
When it hits the ground, s(t) = 0
At t = 3 s it will hit the fround.
We need to find its velocity when it hits the ground.
Differentiate equation (1) to find its velocity.
...(2)
Put t = 3 in equation (2)
Hence, when it will ground its velocity is 80 ft/s.
Answer:if your lookin for what p = then here
Step-by-step explanation:
10p−14=9p+17
Subtract 9p from both sides.
10p−14−9p=17
Combine 10p and −9p to get p.
p−14=17
Add 14 to both sides.
p=17+14
Add 17 and 14 to get 31.
p=31
