9. What is the vertex of the function? f(x) = 3x² - 8x + 10​

Mathematics
1 answer:
Delvig [45]2 years ago
7 0

Answer:

The vertex of the function is (1.333, 4.667)

Step-by-step explanation:

1. Calculate -b / 2a. This is the x-coordinate of the vertex.

2. simply plug -b / 2a into the equation for x and solve for y.

Y = 3x^{2}  - 8x + 10\\Compare with the form of   y = ax^{2} + bx + c\\So that means a = 3, b = -8, and c = 10.

Calculate -b/2a:

X = -(-8)/2(3)

X = 8/6

This is equal to 1.33 recurring

Plug 8/6 for x and solve for y:

Y = 3x^{2} - 8x + 10

Y = 3(\frac{8}{6})^{2} - 8(\frac{8}{6}) + 10

Y = \frac{48}{9} - \frac{64}{6} + 10\\

This is equal to 4.66 reccuring.

Plot each of the three elevations as a point on a vertical number line. Label each point with its numerical value
Whitepunk [10]

What is Elevation ?

When the height of a point is its vertical distance above or below the surface of a reference plane you have selected, it is called the elevation of that point. When the height of a point is its vertical distance above or below mean sea level , it is called the altitude of the point.

Elevation is defined as the height above the ground or other surface, or a place or position of height. An example of elevation is a plane flying at 36,000 feet above the ground. An example of elevation is a pope being raised to the position of saint.

If you go out to eat with 3 friends and your meal was $72.50, there is 6.75% sales tax
netineya [11]

After the tax and the tip are counted, we conclude that each friend must pay $30.

<h3>How much should each person pay?</h3>

We know that the meal cost is $72.50.

Now, there is a 6.75% sales tax and a 15% tip on the waiter (we assume that the tip is based on the total meal cost, after the tax is applied).

Then the total meal cost is:

C = $72.50*( 1 + 6.75%/100%) = $72.50*(1 + 0.0675) = $77.39

Now we also need to add the tip, which is a 15% of that, so the total cost with the tip included is:

C' = $77.39*(1 + 15%/100%) = $88.998 = $90

(Where we rounded up).

Then, if there are 3 friends, each one must pay:

$90/3 = $30

Each friend must pay $30.

A rectangle has an area of 120 square cm. Its length and width are whole numbers. List the possible dimensions of the rectangle.
Nadusha1986 [10]

Answer: kindly check explanation

Step-by-step explanation:

Given that:

Area of rectangle = 120 cm²

Assume ; Length and width are whole numbers

Possible dimension of the rectangle will be :

Area of a rectangle = Length × width

Area = 120cm²

Possible dimensions :

80cm by 1 cm

40cm by 2cm

20cm by 4cm

10cm by 8cm

5cm by 16cm

Possibility which gives the smallest perimeter :

Dimension = 10cm by 8cm

Perimeter of Rectangle = 2(length + width)

Perimeter of Rectangle :

= 2(10 + 8)cm

= 2(18)cm

= 36cm

Given the endpoint A(1, 3) and the midpoint C(6, 2), find the other endpoint B(x, y).
Tpy6a [65]

Right away we know we don't have fractions; the midpoint is the average of the coordinates, so if it and one endpoint are integers so is the other endpoint.

We can do a kind of point arithmetic:

C = (A+B)/2

2C = A+B

B = 2C - A

B = 2(6,1) - (1,3) = (12,2)-(1,3)=(11,-1)

Answer: That's none of the above, but a typo away from the first choice.
