The coefficient 6.3 rounds to 6
The coefficient 9.9 rounds to 10
So we go from this
(6.3 x 10^(-2))(9.9 x 10^(-3))
To this
(6 x 10^(-2))(10 x 10^(-3))
Multiply out the coefficients to get 6*10 = 60
Add the exponents to get -2 plus -3 = -5
So we end up with 60 x 10^(-5)
Be careful. This is NOT the final answer. We need to convert this to scientific notation
60 = 6*10 = 6 x 10^1
60 x 10^(-5) = ( 6 ) x 10^(-5)
60 x 10^(-5) = ( 6 x 10^1 ) x 10^(-5)
60 x 10^(-5) = 6 x (10^1 * 10^(-5)
60 x 10^(-5) = 6 x 10^(1+(-5))
60 x 10^(-5) = 6 x 10^(-4)
The final answer is choice A
Answer:
B. 2/5 barrel/hour
Step-by-step explanation:
cross multiply 1/5 and 2/1
=2/5
V=127.16pi m^3
The formula for the Volume of a Cylinder is V=(pi)r^2h
First we have to fill in the variables with the information we have. The radius is 3.4m. The height is 11m. We want to leave the answer in terms of pi, so we won't multiply by pi at all. Let's plug it in.
V=(pi)3.4^2•11
To square a number we multiply it by itself, so 3.4 • 3.4 equals 11.56.
V=(pi)11.56•11
Next, we multiply the radius squared, which we already found by the height of the cylinder which is 11. 11.56 times 11 equals 127.16.
V=127.16pi
We found the final answer and don't use pi since we want it in terms of pi. Since a Cylinder is a 3-D figure, that means the units of measurement is cubed.
The answer is A) 127.16pi m^3
we are given
graph of a quadratic function
Quadratic function:
Those function which has degree=2
we can write it as
Since, the degree is 2
so, the shape of the curve will be parabolic
so, option-B.........Answer
Assuming it’s a rectangle, the dimensions should be 10ft by 6ft or something like that
