<span>width = x
</span><span>length = 2x
x * 2x = 30
2x</span>² = 30
x² = 15
x = √15 ≈ 3.87 yds ← width
length = 2x = 2√15 ≈ 7.74 yds
Answer:
m = -3
b = 4
Step-by-step explanation:
you dont have that choice tho....but thats the answer
Make sure that you are looking at the right boxes
Answer:
S = π( 2(9) + 2(3)(14))
Step-by-step explanation:
Here we are to select which of the options best describe the equation that could be used to find the surface area of the cylinder.
Mathematically,
the surface area of a cylinder can be calculated using the formula
S = 2 π r^2 + 2 π rh
from the question, we have r as d/2 = 6/2 = 3cm and h = 14cm
We plug these two values into the equation above
Thus, we have
S = 2 * π * 3^2 + 2 * π * 3 * 14
S = π( 2(9) + 2(3)(14))
Answer:
Step-by-step explanation:
According to the law of logarithm;
Given
Comparing with the original expression;
a = 9, b = 2 and c = 2x - 1
Substitute into the result indicinal expression;
This gives the required exponential equation
