Step-by-step explanation:
A geometric random variable X with parameter p has probability function:

<span>To fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and vertical asymptotes.
A sign chart is a chart which help in solving polynomial inequalities.</span>
1. y=4x
2. (I am not able to graph it, but here are some points on the line.)
(0,3) (3,6) (5,8) those three should get you to graph a line. When you have these types of problems, make a table. plug in random numbers, that are reasonable, usually 1-6, and plug them into the equation and enter your new y values, then graph the ordered pairs and connect them.
Answer:
x^2-2x+1
Step-by-step explanation:
f(x)=x^2
g(x)=x-1
f(g(x))=f(x-1)=(x-1)^2=x^2-2x+1
Answer:
Step-by-step explanation:
<u>Use the law of cosines to find the side AB:</u>
<u>Use the Heron's area formula next:</u>
, where s- semi perimeter
- s = 1/2[x + x + 3 +
) = 1/2 (2x + 3 +
) - s - a = 1/2 (2x + 3 +
- 2x - 6) = 1/2 (
- 3) - s - b = 1/2 (2x + 3 +
- 2x) = 1/2 (
+ 3) - s - c = 1/2 (2x + 3 +
- 2
) = 1/2 (2x + 3 -
)
<u>Now</u>
- (s - a)(s - b) = 1/4 [(x²+3x+9) - 9] = 1/4 (x² + 3x)
- s(s - c) = 1/4 [(2x + 3)² - (x² + 3x + 9)] = 1/4 (3x²+ 9x) = 3/4(x² + 3x)
<u>Next</u>
- A² = 3/16(x² + 3x)(x² + 3x)
- 300 = 3/16(x² + 3x)²
- 1600 = (x² + 3x)²
- x² + 3x = 40
<u>Substitute this into the first equation:</u>
