I need to find the equation of the line. Can someone please help?

NikAS [45]

The formula is y = mx + b when b = y-intercept and m is the slope.

Slope = Rise/Run So 1/2.

Y-Int. = The y value at which x = 0. Which is -3

The line has the formula:

Y = 1/2x - 3

Hope this helps :)

A team is being formed that includes eight different people. There are eight different positions on the teams. How many differen

abruzzese [7]

Answer:

40320 different ways

Step-by-step explanation:

That problem is a permutation one

We have eight people to occupy one position in a team, without any constraint at all

Total number of events = P(8)

P (8) = 8!

P (8) = 8*7*6*5*4*3*2*1

P (8) = 40320 different ways

What is the area? Please help!!!

anyanavicka [17]

Answer: 96 ft²

Step-by-step explanation:

<u>This figure can be divided into two rectangles:</u>

The first rectangle has dimensions 6 ft by 14 ft.
The second rectangle had dimensions 4 ft by 3 ft.

<u />

<u>Find the area of both rectangles:</u>

The first rectangle: 6 × 14 = 84 ft²
The second rectangle: 4 × 3 = 12 ft²

<u />

<u>Add them together to find the total area of the figure:</u>

84 + 12 = 96 ft²

Using an exponential function, it is found that the Tequesta settlement is 1845 years old.

<h3>What is an exponential function?</h3>

The exponential equation for a decaying amount of a substance is given by:

$A(t) = A(0)e^{-rt}$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

Researching on the internet, the half-life of carbon 14 is of 5,730 years, hence A(5730) = 0.5A(0), which we use to find r.

$A(t) = A(0)e^{-rt}$

$0.5A(0) = A(0)e^{-5730r}$

$e^{-5730r} = 0.5$

$\ln{e^{-5730r}} = \ln{0.5}$

$5730r = -\ln{0.5}$

$r = -\frac{\ln{0.5}}{5730}$

$r = 0.00012096809$

Hence, the equation is:

$A(t) = A(0)e^{-0.00012096809t}$

The wood chips were found to contain 80% of the atmospheric carbon-14, hence we have to find t for which A(t) = 0.8A(0).

$A(t) = A(0)e^{-0.00012096809t}$

$0.8A(0) = A(0)e^{-0.00012096809t}$

$e^{-0.00012096809t} = 0.8$

$\ln{e^{-0.00012096809t}} = \ln{0.8}$

$-0.00012096809t = \ln{0.8}$

$t = -\frac{\ln{0.8}}{0.00012096809}$

$t = 1845$

The Tequesta settlement is 1845 years old.
