To express it in scientific notation, we have to write the first digit that appears after the zeroes, this is 2. Now, write the decimal dot after it and the others digits after that.
The exponent of 10 will be the number of zeroes in the left including the one that is before the decimal dot in negative form:

Answer:
y = x - 4
Step-by-step explanation:
equation of a line can be expressed as
(x - x1)/(x2 - x1) = (y - y1)/(y2 - y1)
(x - 5)/(10 - 5) = (y - 2)/(-3 - 2)
cross multiplying,
-5(x - 5) = 5(y - 2)
clearing the parentheses
-5x + 10 = 5y - 10
hence,
5y = 5x - 20
y = x - 4
Answer:
Step-by-step explanation:
To find the total surface area of a cylinder
We get
S.A=2πr^2+2πrh
S.a=2×3.142×4×4+2×3.142×4×16
S.A=100.544inches sq+401.192inches sq
S.a=502.464inches sq
