Each member drinks 5t gallons
So 11 members will drink 11*5t=55t gallons

If the island starts with 800 gallons and 55t are removed, then
f(t)=800-55t

Find the distance between the two points in simplest radical form.<br> (-9,5) and (0,0)
7nadin3 [17]

Answer:

\sqrt{106} units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 9, 5)

d = \sqrt{(-9-0)^2+(5-0)^2}

   = \sqrt{(-9)^2+5^2}

   = \sqrt{81+25}

    = \sqrt{106}

3. Which expression is equivalent to log532?
saul85 [17]

Answer: The Nth power xN of a number x was originally defined as x multiplied by itself, until there is a total of N identical factors. By means of various generalizations, the definition can be extended for any value of N that is any real number.

(2) The logarithm (to base 10) of any number x is defined as the power N such that

x = 10N

(3) Properties of logarithms:

(a) The logarithm of a product P.Q is the sum of the logarithms of the factors

log (PQ) = log P + log Q

(b) The logarithm of a quotient P / Q is the difference of the logarithms of the factors

log (P / Q) = log P – log Q

(c) The logarithm of a number P raised to power Q is Q.logP

log[PQ] = Q.logP

We need to find what percent of $84 is $12.

To find what percent a part is of a whole, divide the part by the whole and multiply by 100.

12/84 * 100% = 14.2857...%

Answer: 14.3%
