Part A: Find the area of the circle of spilled milk as a function of time, or A[r(t)].
A(r(t)) = A(4t) = π(4t)^2 = 16πt^2
A[r(t)] = 16πt^2
Part B: How large is the area of spilled milk after 4 minutes? You may use 3.14 to approximate π in this problem.
After 4 minutes, A = 16(3.14)(4)^2 = 803.84 cubic meters.
Answer:
x = -y + 7
or
x = 7 - y
Step-by-step explanation:
x + y = 7
Step 1: Subtract y from both sides to get x alone.
x + y = 7
-y -y
x = 7 - y
Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.
The answer should be .4 X cubed +1300 X squared -300+50
The productivity of labor increases by 5% would cause the firm to increase hiring capital and decrease hiring of labor
<u>Step-by-step explanation:</u>
A company can convert input data to output data. So, it gets divided the data into broad categories called production factors. Productivity variations, or more precisely the marginal products of labour, work in the same way as differences in real wages. Remember that marginal prices depend on both - real wages and the productivity.
If in case, productivity increases, perhaps because the company has increased its capital base, thereby marginal costs will decrease. Companies will produce more products and employ more employees. Conversely, if productivity drops, companies will produce less and destroy jobs.
The problem is asking you to simplify the exponents. When you multiply two or more powers with the same base, the exponents can be added and subtracted. In this case, the base is 7.
7 can also be written as
.
The answer would be 7³ if you kept the exponent, or 343 if you simplified further.
