A) I=PRT
I=3000(.12)(2)
I=$720
In equation 1, When x = 0, y = -3 ( 0, -3)
And when y = 0, x = -3....( 3,0)
In equation 2, when x = 1, y = -4(1,-4)
and when y = 2, x = 5....(5,2)
You have to plot the points on graph paper and the solutions are where the two lines intersect.
You can use any points for x and y.
Answer:
t = ln(0.5)/-r
Step-by-step explanation:
The decay rate parameter is missing. I will assume a value of 4% per day.
The exponential decay is modeled by the following equation:
A = A0*e^(-r*t)
where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).
At half-life A = A0/2, then:
A0/2 = A0*e^(-0.04*t)
0.5 = e^(-0.04*t)
ln(0.5) = -0.04*t
t = ln(0.5)/-0.04
t = 17.33 days
In general the half-life time is:
t = ln(0.5)/-r
Answer: 17 inches
Explanation: so we have a triangle with the two side lengths 8 and 15 and we’re trying to find the hypotenuse. so using the pythagorean theorem, we have 8^2 + 15^2 = c^2. when we solve we get 64 + 225 = c^2, which is 289 = c^2. next, we find the square root of both sides and c = 17 inches.
hope this helped!
The formula of a slope:
We have the points (2, 2) and (-1, -4).
Substitute:
