The function A(t) = 1950 (0.65)t models the amount A(t) , in dollars, that Ted's company deducts from his check for health insurance based on time t, in months that Ted has worked for the company. Determine the rate used in this formula and identify as growth or decay.

Answers

Answer 1

Answer:

This is an Exponential decay

The Exponential decay rate = 35%

Step-by-step explanation:

Looking at that the above question, it is an Exponential decay

The formula for Exponential decay is:

A(t) = Ao (1 - r)^t

In the above question:.

A(t) = 1950 (0.65)^t

r = rate

Hence:

(1 - r) = (0.65)

1 - r = 0.65

r = 1 - 0.65

r = 0.35

Converting to percentage

0.35 × 100

= 35%

Hence, the Exponential decay rate is 35%

Answers

Answer:

x=2.202545727

Step-by-step explanation:

Use the Law of Sines:

a=b(sinα /sinβ)

3x+12=(x+25)(sin40 /sin70)

3x+12=(x+25)(0.6840402867)

3x+12=0.6840402867x+17.10100717

2.315959713x+12=17.10100717

2.315959713x=5.10100717

x=2.202545727

So x=2.202545727

Write the equations of the fully simplified slop-intercept form.​

Answers

Answer:

y = -6x - 4

Step-by-step explanation:

Using two points on the line, (0, -4) and (-1, 2),

[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - (-4)}{-1 - 0} = \frac{6}{-1} = -6 [/tex]

m = -6

y-intercept (b) = -4 (the value of y when x = 0)

To write the equation, substitute m = -6, and b = -4 into y = mx + b

y = -6x - 4

Okay so you a chart with increments of 5 years between each recorded population. Each 5 years the population decreases more than the previous 5 years until you get to 2010 where it had decreased more between 2005 than it did by 2010. This means the population does not decrease at a certain percentage or by a specific equation. It is more random but has the common pattern that it decreases. Guirllimo basically has his own equation where he thinks he can predict the what the population would be at any given time after the year 1990. In his equation you can test it out where the t stand for years after 1990. They want to know what the population would be after 5 years according to his equation. To do this you replace t by 5 which is the years after 1990. So -26x5+5649= guirllimos estimated population . -26x5= -130. -130+5649= 5519. 5519 is guirllimos estimated number of what the population would be according to his equation. According to the data he recorded the actual data population was 5530. According to his calculation he was only off the actual amount by 11 people. This is a close estimate but like I said the population decreases by not by any specific percentage or equation. Even tho this is true his equation seems to be within 50 people of a difference than what the actual answer would be. This is pretty good given the population is more at a random rate than a controlled rate.

What is the slope of the line given by the equation 4x−7y=5?

Answers

Answer:

4/7 or 4 up, 7 to the right.

Step-by-step explanation:

We have to isolate y, so if we subtract 4x from both sides we get:

-7y = -4x + 5

Then we divide by -7

y = 4/7x + 5/7

The slope is 4/7 or 4 up, 7 to the right.
