What is true about the sum of the two polynomials?
const2013 [10]

Answer:

f'(x) = -f(x) = 9xy² - 6x²y + 5x³

Step-by-step explanation:

f(x) = –9xy² + 6x²y – 5x³

additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³

f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0

Jeremias invested $20 at a rate of 8.5% compounded continuously. How long would it take to triple his money?
3241004551 [841]

Answer:

  • 13

Step-by-step explanation:

<u>Use formula for continuous interest:</u>

  • A = Pe^{rt}, where r- interest rate, t- time in years

<u>If A = 3P, and r = 0.085 then the equation is:</u>

  • 3P = Pe^{0.085t}
  • 3 = e^{0.085t}
  • ln 3 = 0.085t
  • 1.099 = 0.085t
  • t = 1.099 / 0.085
  • t = 12.9 ≈ 13 years

8^x times 2^(4-x) = 1<br> Find x.<br> With detailed steps.
Dafna1 [17]

Answer: x= -1

Step-by-step explanation:

In mathematics when you have bases that are the same while multiplying you add the powers. In this case we do not have the same bases so we are going to make it look like 8 is 2. So we sort of simplify it. So we get 8 and put into like 2^4. We do not eliminate the power x that was already there though. So we will have 2^4x × 2^4-x. So like I said earlier we add the powers. Soo we will have

  1. 4x +4-x
  2. 4x-x=1
  3. 3x+4-4 =1-4
  4. 3x/3 = -3/3
  5. x= -1

The cost of a ticket to the circus is $19.00 for
DENIUS [597]

<u>Answer:</u>

The number of tickets bought is 1000 adults tickets and 700 children were present  

<u>Explanation:</u>

Let the number of children and adults present in the circus be x and y respectively

According to question,

Then, x + y = 1700  ……………..equation (1)

And, cost of ticket to circus for children and adult be 19, 42 respectively

Total cost of ticket;

for adults = 42y; for children = 19x

19x + 42y = 55300  …………………equation (2)

Multiplying equation (1) by 19

19x + 19y = 32300  ……………… eqn (3)

Subtracting equation 1 and 3, we get

23y = 23000

y = 1000

putting this value in eq (1), we get x = 700

Therefore, 1000 adults and 700 children were present .
