Answer:
spend what
Step-by-step explanation:
Do you see that when we change
f(x) = 7x - 5
to
f(2) = 7(2) - 5
we are simply saying to substitute in 2 for x? Well that is what we are doing:
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9
Now we find g(4) the same way:
g(x) = 4(x)
g(4) = 4(4)
g(4) = 16
Now we find the difference of the two functions:
f(2) - g(4)
9 - 16
-7
So, the answer is B.
Pi is an irrational and a real number
Multiplying the values given above we obtain a value of 0.01386. In scientific notation, 1.386 x 10^-2. <span>The </span>significant figures<span> of a number are </span>digits<span> that carry meaning contributing to its measurement resolution. From the multiplicand and the multiplier, the least number of significant significant figure would be one. Therefore, we write as
1.0 x 10^-2</span>
Step-by-step explanation:
First of all we need to know the formula for the circumference which is:
We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.
The formula for the area is: Solve for r;
Now that we've found the radius, we simply plug it into the circumference formula.
