Answer:

  P = 20000×1.625^(n/4)

Step-by-step explanation:

An exponential equation can be written using the given data:

  value = (initial value)×(growth factor in period)^(n/(period))

Here, the growth is by a factor of 32500/20000 = 1.625, and the period is 4 years. Then your exponential equation is ...

  P = 20000×1.625^(n/4)

Problem 44. The sum of a certain quantity "p" together with two-third of that number, and one-third of that number, becomes 234.
emmainna [20.7K]

Answer:

p=117

Step-by-step explanation:

Given number is p.

Two-third of the number = \frac{2}{3}p

One-third of the number = \frac{p}{3}

The sum of a certain quantity p together with two-third of that number, and one-third of that number, becomes 234.

p+\frac{2}{3}p+\frac{p}{3}=234\\\\\frac{3p+2p+p}{3}=234\\\\\frac{6p}{3} =234\\\\2p=234\\p=117

Find the value of y in the equation attached to this question
dlinn [17]

Answer:

y = 4

Step-by-step explanation:

1) Simplify 3^5 to 243.

{9}^{y}=\frac{243\times {9}^{6}}{{27}^{3}}

2) Simplify {9}^{6} to 531441.

{9}^{y}=\frac{243\times 531441}{{27}^{3}}

3)  Simplify  243\times 531441 to  129140163.

{9}^{y}=\frac{129140163}{{27}^{3}}

4) Simplify  {27}^{3}  to  19683.

{9}^{y}=\frac{129140163}{19683}

5) Simplify  \frac{129140163}{19683} to 6561.

{9}^{y}=6561

6) Convert both sides to the same base.

9^y=9^4

7)  Cancel the base of 9 on both sides.

y=4
