Answer:

The average height of poodles in your kennel is 25.19 inches.

Step-by-step explanation:

This is a weighed average problem.

To find the weighed average, we sum each value of the set multiplied by it's weight, and then we divide by the sum of the weights.

In this problem, we have that:

Average 20.5 inches has weight 28.

Average 32.1 inches has weight 19.

What is the average height of poodles in your kennel?

$A = \frac{32.1*19 + 20.5*28}{19+28} = \frac{1183.9}{47} = 25.19$

The average height of poodles in your kennel is 25.19 inches.

QUESTION 1

The given logarithm is

$8\log_g(x)+5\log_g(y)$

We apply the power rule of logarithms; $n\log_a(m)=\log_(m^n)$

$=\log_g(x^8)+\log_g(y^5)$

We now apply the product rule of logarithm;

$\log_a(m)+\log_a(n)=\log_a(mn)$

$=\log_g(x^8y^5)$

QUESTION 2

The given logarithm is

$8\log_5(x)+\frac{3}{4}\log_5(y)-5\log_5(z)$

We apply the power rule of logarithm to get;

$=\log_5(x^8)+\log_5(y^{\frac{3}{4}})-\log_5(z^5)$

We apply the product to obtain;

$=\log_5(x^8\times y^{\frac{3}{4}})-\log_5(z^5)$

We apply the quotient rule; $\log_a(m)-\log_a(n)=\log_a(\frac{m}{n} )$

$=\log_5(\frac{x^8\times y^{\frac{3}{4}}}{z^5})$

$=\log_5(\frac{x^8 \sqrt[4]{y^3} }{z^5})$

So first you will need to multiply 9 by 4. You get 36. Now you need to add the 10 percent and you get 39.6! That's the answer!

Answer:

x + 4y

Step-by-step explanation:

(x∧2+8xy+16y∧2)∧(1/3) · (x+4y)∧(1/3) = ((x+4y)∧2 · (x+4y))∧(1/3) = ((x+4y)∧3)∧(1/3)=

= (x+4y)∧(3/3) = x+4y

Good luck!!!
