What is the value of b^2 0 4ac for the following equation?2x^2 0 2x 0 1 = 0
04
0
12

Answers

Answer 1
Answer: 2x^2 - 2x - 1 = 0 a = 2, b = -2, c = -1 b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12
so the answer is 12

_______________

The distance in meters of a basket suspended on a spring to a tabletop below is dependent on the number of steel bearings in the basket. The function representing this relationship is d(m) = 7 – 2m, where d(m) represents the distance in meters, and m represents the number of steel bearings in the basket. Which set represents the evaluation of the function d(m) = 7 – 2m when m ∈ {0, 1, 2, 3}?

Answers

The set representing the evaluation of the function d(m) for m ∈ {0, 1, 2, 3} is {7, 5, 3, 1}.

What is the set of the evaluation?

To evaluate the function d(m) = 7 - 2m for different values of m, we simply need to substitute each value of m from the given set {0, 1, 2, 3} into the function and compute the corresponding d(m) values.

Let's calculate d(m) for each value of m:

For m = 0:

d(0) = 7 - 2(0) = 7

For m = 1:

d(1) = 7 - 2(1)= 7 - 2 = 5

For m = 2:

d(2) = 7 - 2(2) = 7 - 4 = 3

For m = 3:

d(3) = 7 - 2(3) = 7 - 6 = 1

So the set representing the evaluation of the function d(m) for m ∈ {0, 1, 2, 3} is {7, 5, 3, 1}.

180(.6) because 40% off is 0.4 and what is left over is 60% or 0.6. When you multiply this you get 108. 5% sales tax is a 5% increase, so multiple 108(1.05) and you get $113.40.
