Determine what type of model best fits the given situation:
lyudmila [28]

Let value intially be = P

Then it is decreased by 20 %.

So 20% of P = \frac{20}{100} \times P = 0.2P

So after 1 year value is decreased by 0.2P

so value after 1 year will be = P - 0.2P (as its decreased so we will subtract 0.2P from original value P) = 0.8P-------------------------------------(1)

Similarly for 2nd year, this value 0.8P will again be decreased by 20 %

so 20% of 0.8P = \frac{20}{100} \times 0.8P = (0.2)(0.8P)

So after 2 years value is decreased by (0.2)(0.8P)

so value after 2 years will be = 0.8P - 0.2(0.8P)

taking 0.8P common out we get 0.8P(1-0.2)

= 0.8P(0.8)

=P(0.8)^{2}-------------------------(2)

Similarly after 3 years, this value P(0.8)^{2} will again be decreased by 20 %

so 20% of P(0.8)^{2}  \frac{20}{100} \times P(0.8)^{2} = (0.2)P(0.8)^{2}

So after 3 years value is decreased by (0.2)P(0.8)^{2}

so value after 3 years will be = P(0.8)^{2}   - (0.2)P(0.8)^{2}

taking P(0.8)^{2} common out we get P(0.8)^{2}(1-0.2)

P(0.8)^{2}(0.8)

P(0.8)^{3}-----------------------(3)

so from (1), (2), (3) we can see the following pattern

value after 1 year is P(0.8) or P(0.8)^{1}

value after 2 years is P(0.8)^{2}

value after 3 years is P(0.8)^{3}

so value after x years will be P(0.8)^{x} ( whatever is the year, that is raised to power on 0.8)

So function is best described by exponential model

y = P(0.8)^{x} where y is the value after x years

so thats the final answer

Find the x intercept and y intercept for 6x-2y=18 . provide an explanation and show steps
allochka39001 [22]

Answer:

The slope intercept form would be y = 3x - 9

Step-by-step explanation:

To find this slone in slope intercept form, all we need to do is solve for y.

6x - 2y = 18 ---> Subtract 6x from both sides

-2y = -6x + 18 ----> Divide both sides by -2

y = 3x - 9

What is the height of a
vagabundo [1.1K]

Answer:

12 meters

Step-by-step explanation:

The area of a parallelogram can be found using:

a=bh

We know that the base is 7 meters, and the area is 84 square meters. Therefore, we can substitute 7 in for b, and 84 in for a.

84=7h

We want to find the height. To do this, we have to get h by itself. Since h is being multiplied by 7, divide both sides by 7.

84/7=7h/7

12=h

So, the height is 12 meters
