The quadratic function that passes through the point  (0,6), (3,15.8), and (9.5,0) is y = -0.6x² + 5.07x + 6

<h3>How to determine the quadratic function?</h3>

The points are given as:

(0,6), (3,15.8), and (9.5,0)

A quadratic function is represented as:

y = ax² + bx + c

Next, we substitute the points in the equation.

a(0)² + b(0) + c = 6

a(3)² + b(3) + c = 15.8

a(9.5)² + b(9.5) + c = 0

Simplify the expressions

c = 6

9a + 3b + c = 15.8

90.25a + 9.5b + c = 0

Solve for a, b and c using a graphing calculator

a = -0.6

b = 5.07

c = 6

Hence, the quadratic function is

y = -0.6x² + 5.07x + 6

Cost of computer $1000.00 (listed in order)
agasfer [191]
The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.

1. In the figure, m DE = 106 degrees and m BC = 62 degrees. The diagram is not to scale.
k0ka [10]
For question 1, the formula for that is m1= 1/2(a-b). 106 being A and 62 being B. You should get m1=.5*(106-62) which equals B.22

Can someone help? Thanks :D
Rufina [12.5K]

Answer:

y\leq -x+4

Step-by-step explanation:

The first thing that we can do is look at the equation of the line and then worry about the inequality afterwards.

This line has a y-intercept of 4 and a slope of -1.

This means that the equation of this line would be y=-x+4

Now that we have the equation of the line, we just need to determine which inequality sign to use.

As the shaded region is BELOW the line, we will use a less than (<) sign.

As the line is fully shaded, I can only assume that it is meant to include the line, which would mean that y\leq -x+4 would be the equation for this inequality.
