Solve the following system of equations. -3x-7y=-3-2x+5y=-2
1) Let's solve that system by elimination. We'll eliminate the x terms firstly:
Since the LMC, between 3 and 2 is 6 let's multiply the first and the second equation to get 6x
-3x-7y=-3 x -2
-2x+5y=-2 x 3
6x +14y= 6
-6x+15y=-6
-------------------------
0 + 29y = 0
y= 0
2) Now let's plug into one of those equations, usually the simpler one, that value for y. To find out the x.
-2x +5y=-2
-2x +5(0) =-2
-2x= -2
2x=2 Divide both sides by 2
x=1
3) So the solution for this system is (1,0).

The given triangle is a right triangle because one of its angles is 90 degrees. We would find b by applying the pythagorean theorem which is expressed as
hypotenuse^2 = one leg^2 + other leg^2
From the information given,
hypotenuse = 17
one leg = 7
other leg = b
Thus,
17^2 = 7^2 + b^2
289 = 49 + b^2
b^2 = 289 - 49 = 240
b = √240
b = 4√15

Write each rate as a fraction in lowest terms 5 feet in 35 seconds
The rate 5/35 feet per seconds as a fraction in lowest terms would be 1/7
In this question we need to write each rate as a fraction in lowest terms 5 feet in 35 seconds.
The rate would be feet per seconds.
i.e., 5/ 35
To convert this rate in simplest terms, we need to reduce all common factors.
5 = 5 × 1
and 35 = 5 × 7
So, the rate would be,
5/35 = (5 × 1)/(5 × 7)
5 is the common factor for both the numbers 5 and 35.
5/35 = 1/7 ..........(cancel the common factor)
Therefore, the rate 5/35 feet per seconds as a fraction in lowest terms would be 1/7

make up a story for the graph below. describe all 5 events A-E of your story. note whether you mention whether your events are decreasing increasing or constant distance
Explanation:
We need to describe a story such that for event A, C, and E the distance is increasing, for event B the distance is constant, for event D, the distance is decreasing. So, the story is:
Answer:
On a specific day, you decided to travel to another city with your friends but you are the only one with a car, so you need to pick up each of your friends, so the y-axis represents the distance from your home.
So, event A is when you go to pick up your first friend that lives 2 hours away. This friend wasn't ready so you wait for an hour (event B). Then you go to the house of your second friend (event C) and at that moment you realize that you forget a third friend that lives closer to your house, so you have to come back to his house (event D). Finally, they start to travel to the city (event E).

Answer:
electrical
Step-by-step explanation:
You want the kind of energy produced by a windmill's generator.
WindmillA typical windmill has airfoils in the wind stream that are connected to a shaft that rotates when the wind moves them. The rotation of the shaft turns the rotor in a generator, which causes wire to move through a magnetic field, producing a current in the wire. That current represents electrical energy produced by the generator.
Construct sinusoidal functionsThe graph of a sinusoidal function intersects its midline at (0, -3) and then has a maximum point at (2, -1.5).Write the formula of the function, where x is entered in radians.
We have a sinusoidal function.
[tex]y=A\cdot\sin (b\cdot x+c)+d[/tex]Its midline is intersected at (0,-3) and has a maximum point at (2,-1.5).
As the midline intersects at y=-3, we know that function has an offset of 3 units down.
This offset is the value of the parameter d, so we have:
[tex]y=A\cdot\sin (b\cdot x+c)-3[/tex]The maximum value happens at point (2,-1.5). The maximum value happens when the pure sin function reaches the value 1, so we can write:
[tex]\begin{gathered} y_{\max }=A\cdot1-3=-1.5 \\ A-3=-1.5 \\ A=-1.5+3 \\ A=1.5 \end{gathered}[/tex]The amplitude is A=1.5, so we can write:
[tex]y=1.5\sin (b\cdot x+c)-3[/tex]We can find the values of the parameters b and c using the x-values of the the points (0,-3) and (2,-1.5):
[tex]\begin{gathered} (x,y)=(0,-3) \\ y(0)=1.5\sin (b\cdot0+c)-3=-3 \\ 1.5\cdot\sin (c)=-3+3 \\ 1.5\cdot\sin (c)=0 \\ \sin (c)=0 \\ c=0 \end{gathered}[/tex][tex]\begin{gathered} (x,y)=(2,-1.5) \\ y(2)=1.5\cdot\sin (b\cdot2)-3=-1.5 \\ 1.5\cdot\sin (2b)=-1.5+3 \\ 1.5\cdot\sin (2b)=1.5 \\ \sin (2b)=1 \\ 2b=\frac{\pi}{2} \\ b=\frac{\pi}{2}\cdot\frac{1}{2} \\ b=\frac{\pi}{4} \end{gathered}[/tex]The function becomes:
[tex]y(x)=1.5\sin (\frac{\pi}{4}x)-3[/tex]The graph of the function is:

5 = 60(0.93)^x
Initial value:
Growth or Decay:
Growth/Decay Rate:
Initial value is 60 and growth factor is -0.93 in this instance.
How are growth and decay determined?The formulas f(x) = a(1 + r)t and f(x) = a(1 - r)t provide the necessary computations for the exponential growth and decay. Here, t is the length of time or the time factor, an is the initial quantity, r is the growth or decay constant.
The formula is 5 = 60(0.93)^x.
The beginning value and growth/decay factor should be determined.
Solution:
Y = a(1+r)^x is the formula for the exponential growth/decay model in general (i)
where an is the starting value, r>0 indicates growth factor, r0 indicates decay factor, and x indicates time.
As a result, 5 = 60(0.93)^x.
It can be expressed mathematically as 5 = 60(1 + (-0.93))x (ii)
We obtain a = 60 and r = -0.93 when comparing I with (ii).
Initial value is 60 and growth factor is -0.93 in this instance.

Step-by-step explanation:
Empirical Probability is the experimental probability.
The probability formula is
the number of times an event occured/total times all events happen.
We know we rolled the dice 60 times so that will be in the numerator.
We roll 2, 9 times
We roll 4, 12 times
We roll 6, 8 times so

There are three parts to this question. A) The number of people initially infected is? (round to the nearest whole number as needed)
a.
To find the initial number of people infected, let's calculate the value of f(t) for t = 0:
[tex]f(0)=\frac{102000}{1+5200e^0}=\frac{102000}{1+5200}=\frac{102000}{5201}=19.61[/tex]Rounding to the nearest whole number, the initial value is 20 people.
b.
Using t = 4, let's calculate the value of f(t):
[tex]f(4)=\frac{102000}{1+5200e^{-4}}=\frac{102000}{1+5200\cdot0.0183156}=\frac{102000}{96.24112}=1.059.84[/tex]Therefore the number of infected people is 1060.
c.
When t tends to infinity, the value of 5200e^-t will tend to zero, therefore we have:
[tex]\lim_{t\to\infty}f(t)=\frac{102000}{1+0}=102000[/tex]Therefore the limiting size is 102000 people.
