Harrizon [31]3 years ago

Answer: The answer is 5x³.

Step-by-step explanation: We are given to simplify the following radical expression:

R_e=3\sqrt{125x^9}.

We are to find the cube root of the 125 and that of x to the power 9 and will multiply both of them to get the complete answer.

The simplification is as follows:

R_e\\\\=\sqrt[3]{125x^9}\\\\=\sqrt[3]{5^3(x^3)^3}\\\\=5^{3\times \frac{1}{3}}\times (x^3)^{3\times\frac{1}{3}}\\\\=5\times x^3\\\\=5x^3.

Thus, the answer is 5x³.

Use the given graph of f to estimate the intervals on which the derivative f ' is increasing or decreasing. (Enter your answers
NARA [144]

The derivative of a function is used to determine whether the function is increasing or decreasing on any intervals in its domain.

Derivative of function f is increasing in interval  (-2 , 1) and (3 , 6)

Derivative of function f is decreasing in interval (1 , 3) and (6 , 9)

If f′(x) > 0 at each point in an interval , then the function is said to be increasing in that interval.

If f′(x) < 0 at each point in an interval , then the function is said to be decreasing on that interval.

By observing graph, it is observed that slope  of function f is positive in interval  (-2 , 1) and (3 , 6) . Hence, derivative of  function f is increasing in interval  (-2 , 1) and (3 , 6)

By observing graph, it is observed that slope  of function f is negative in interval  (1 , 3) and (6 , 9) . Hence, derivative of  function f is decreasing in interval  (1 , 3) and (6 , 9).

Maricopa's Success scholarship fund receives a gift of $ 75000. The money is invested in stocks,
Airida [17]

Answer:

Maricopa's Success invests $25,000 in stocks, $40,000 in bonds, and $10,000 in CDs.

Step-by-step explanation:

a = Stocks

b = Bonds

c = CDs

a + b + c = 75000

b = 30000 + c

a = 75000 - c - 30000 - c = 45000 - 2c

0.065(45000 - 2c) + 0.044(30000 + c) + 0.0225c = 3610

2925 - 0.13c + 1320 + 0.044c + 0.0225c = 3610

0.0635c = 635

c = 10000

So b = 40000 and a = 25000
