Answer:

when f(x) is -1, f(x) = -3

when f(x) is 0, f(x) = 1

when f(x) is 3, f(x)= 13

so is -3, 1 and 13.

you basically replace x with the number and then evaluate

hope is helpful!!

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (4, 6)

Point (-2, -2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $\displaystyle d = \sqrt{(-2-4)^2+(-2-6)^2}$
Subtract: $\displaystyle d = \sqrt{(-6)^2+(-8)^2}$
Exponents: $\displaystyle d = \sqrt{36+64}$
Add: $\displaystyle d = \sqrt{100}$
Evaluate: $\displaystyle d = 10$

10 is 1/10 percent of what number? The answer key says 1,000. Can you please explain why? Thank you.

inn [45]

The key lies in translating "1/10 percent." If the unknown number is n, then 0.001n = 10. Mult. both sides by 1000: n = 10000 (answer)

An initial population of 20 rabbits triples every half year. The function f(x) = 20(3^x) gives the population after x half-perio

luda_lava [24]

The number of rabbits that there will be in 3 years is 14,580.

<h3>What is the number of rabbits in 3 years?</h3>

The growth rates of the rabbits is an exponential growth. The formula that can be used to represent the population of the rabbits in 3 years is:

f(x) = 20(3^x)

Where x represents the number of years. The number of years is 6(3 x 2)

20 x 3^6 = 14,580

How t solve polynomials????? HELPPPP EXAM TMRW!!!!

Alecsey [184]

Answer:

B) 1296 D) 729

Step-by-step explanation:

It's pretty straight forward, just put the values into your calculator. The question is asking to evaluate instead of simplifying, so this works. If you don't have a calculator, here are some tricks. Do them step by step in your head slowly if you have to, for fractions do them alone, and then divide them. Also in D, don't let the second value of (3)3)0 scare you, any exponent with a 0 in it is automatically 1! Hope I could help.
