Answer:
g(x) = -2^x
Step-by-step explanation:
This is an exponential function from the looks of the value for x as it decreases toward the negative value (increase in the absolute value calculation) y is constricted from its vigorous values down to the fractional components of an equation of the standard appearance of y = C^x. For this, try some values. x = 1 y = 2, x = 2 y = 4. There is a trend that is established through these points, and g(x) = -2^x seems to follow this trend as it is reflect across the x-axis. Enter points, it is confirmed and a graphing calculator further substantiates. Try for yourself!
Answer:
-18b + 66
Step-by-step explanation:
-6 + 9(8 - 2b)
-6 + 72 - 18b
-18b + 66
Tim gets 5 and sam gets 25 or 5:25
The method that can be used to randomly choose these 500 people is the use of systematic random sampling.
<h3>What is random sampling?</h3>
Random sampling is defined as the method of sampling in which the whole sampling frame is being considered.
In order the survey a community of people to see whether they are willing to have their taxes increased for one year to fund the construction of the skate park, both the male and female should be considered.
The systematic random sampling will give the both male and female equal opportunity to the chosen.

Answer:
A
Step-by-step explanation:
Givens
- The board has been placed 1/2 the length of the 10 foot ladder across to 1/2 the length of the 15 foot ladder.
- That means that the rung holding the board on the 10 foot ladder is 1/2 up the length of the 10 foot ladder.
- That makes the hypotenuse of the small triangle = 5
- The distance from where the ladders meet to the paint = x
Find x
x^2 + 3^2 = 5^2
x^2 + 9 = 25 Subtract 9 from both sides
x^2 = 25 - 9 Combine
x^2 = 16 Take the sqrt of both sides
x = 4
Find the height
The ratio of all dimensions involving the 2 ladders and the board is 1 to 2.
So the total height from where the ladders meet to the ground is 2*4 = 8
Answer: The distance from the bucket to the ground is 1/2 * 8 = 4
