Answer:

See Explanation

Step-by-step explanation:

Given

Savings = \$500

Withdrawal = \$12 weekly

Required

The question is incomplete as the linear function or table or graph of Melissa's plan is not given.

The available details can only be used to solve the function of the given individual

Let the number of weeks be w.

So: the amount left in w weeks is:

Amount = Savings - Withdrawal * w

Amount = 500- 12* w

Amount = 500- 12w

Represent as a function

f(w)= 500- 12w

To solve the amount left at the end of a certain week (say week 5), simply substitute 5 for w in f(w)= 500- 12w

f(5) = 500 - 12 * 5

f(5) = 440

F(x) = 4x^2+2x+6 what is the discriminant of f? How many distinct real number zeros does f have?
Sunny_sXe [5.5K]

Answer:

The discriminant of f is 92, and it has no real zeros

Step-by-step explanation:

The discriminant of a quadratic is b^2-4ac, where the quadratic is in the form ax^2+bx+c. The discriminant of this one is therefore:

2^2-4(4)(6)=4-96=-92

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!

Three of the four vertices of a rectangle are located at (4, 2), (7, 2) and (4, 8). a. What are the coordinates of the missing v
34kurt

Answer:

a) The coordinates of the missing vertex = (7, 8)

b) Area = 18 square units

   Perimeter = 18 units

Step-by-step explanation:

a) We know three of the four vertices:

A: (4, 2)           C ______ D(?)

B: (7, 2)               |             |

C: (4, 8)           A |______| B  

To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:

B_{x} - A_{x} = 7 - 4 = 3                    

Hence, the distance of point D from point C in the x-direction is:

D_{x} = C_{x} + 3 = 4 + 3 = 7

Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:

C_{y} - A_{y} = 8 - 2 = 6  

Then, the distance of point D from point B in the y-direction is:

D_{y} = B_{y} + 6 = 2 + 6 = 8

Therefore, the coordinates of the missing vertex (point D) are:

D = (D_{x}, D_{y}) = (7, 8)    

b) The area of the rectangle is:

a = (B_{x} - A_{x})*(C_{y} - A_{y}) = 3*6 = 18 units^{2}

The perimeter is given by:

p = 2*(3 + 6) = 18 units

I hope it helps you!
