Answer:

Step-by-step explanation:

Activity 2:

c² - 6c - 40

Sum = -6

Product = -40

Factors= -10 , 4

c² - 6c -40 = c² - 10c - 4c - 10*4

                = c(c - 10) - 4(c - 10)

               = (c -10) (c -4)

e²  + 10e +16

Sum = 10

Product = 16

Factors= 2 , 8

e² + 10e + 16 = e² + 2e + 8e + 2*8

                      = e(e + 2) + 8(e + 2)

                     = (e + 2)(e +8)

h²  - 5h  - 24

Sum = -5

Product = -24

Factors = 3 , -8

h²  - 5h - 24 = h²  + 3h - 8h - 3*8

                     = h(h + 3) - 8(h + 3)

                    = (h +3)(h - 8)

3x²  - 5 x - 12

Sum = -5

Product = -12 * 3 = - 36

Factors = -9 , 4

3x²  - 5x - 12 = 3x²  - 9x + 4x - 4*3

                    = 3x(x - 3) + 4(x - 3)

                   =(x - 3) (3x + 4)

4x²  + 4 x  - 15

Sum = 4

Product = 4 * -15 = - 60

Factors = 10 , -6

4x²  + 4x - 15 = 4x²  + 10x - 6x - 3*5

                      =2x (2x + 5) - 3(2x +5)

                     = (2x + 5)(2x - 3)

I need help.. A diameter of a circle has endpoints p(-10, -2) and q(4, 6)
Phoenix [80]

A: The center is the mid point of the diameter. So, the center of the circle will be the midpoint of points P and Q. The coordinates of the midpoint are the averaged coordinates of the endpoints.

So, the x-cooardinate of the center is the average of the x-coordinates of P and Q:

C_x = \dfrac{P_x+Q_x}{2}=\dfrac{-10+4}{2}=\dfrac{-6}{2}=-3

Try to do the same thing with the y coordinates, and you'll get the y-coordinate C_y. This first part will be over, because the circle will be point

C=(C_x,C_y)

B: The radius is exactly half the diameter. So, we find the length of the diameter, and we divide it by 2. To find the length of the diameter, we use the standard formula for the distance between two points:

d=\sqrt{(P_x-Q_x)^2+(P_y-Q_y)^2}=\sqrt{(-10-4)^2+(-2-6)^2}=\sqrt{260}=2\sqrt{65}

Divide this length by 2 and you'll get the radius.

C: At this point, we have both the radius and the coordinates of the center. The equation of the circle depends on these two parameters, and it is

(x-C_x)^2+(y-C_y)^2=r^2

Substitute C_x and C_y with the coordinates of the center (found in point A.) and r with the radius (found in point B.) and you'll have the equation of the circle.

Stacy goes to the county fair with her friends . The total cost of ride tickets is given by the equation c=3.5t , where c is the
madreJ [45]

Answer:

<h2><u>$52.5</u></h2>

Step-by-step explanation:

Step one:

given data

we are given that the linear function for the cost is  c=3.5t

c is the cost and

t is the number of tickets.

We are told that t=15, to find c, let us put the value of t in the linear function for the cost

c=3.5(15)\\\\c=52.5

<u>This shows that 15 tickets will cost $52.5</u>

Please plot this linear equation on a graph, and also explain how to plot it. <br> <img src="https://tex.z-dn.net/?f=y%3D3x-7" i
olasank [31]

Answer:

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day.

We can solve this equation in a single step, we just need a bit of theory and a graph.

We can first see that its in y=mx+b form. Which is also known as Slope-Intercept form.

This means that we know the following.

  • b is the y coordinate of the y intercept.
  • m is the slope of the line.

Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).

Now that we've gotten that, we can start graphing.

The y intercept is -7 so we can plot (0,-7) as one of our points.

The slope of 3 means that we got up 3 units then right a single unit.

Therefore, another point could be (1,-4).

With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.

Cheers!
