Whats The Axis Of Symmetry?

Answers

Answer 1

Answer:

x = -1

Step-by-step explanation:

With the axis of symmetry, think of it as where you would slice this line in half, and both sides would look identical to each other. Since this is a quadratic function, this would be at where the vertex is.

The vertex is the part of the line where it "turns" around and starts going the other way. So vertex of this line is at (-1, 3).

Therefore, the axis of symmetry is at x = -1. This is since the function is pointing either up/down, and any value that is x = _ is a vertical line.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that A 2-gallon bucket of paint costs $58.00. Therefore, the price per gallon is,

Price per gallon = $58/2

Since a gallon is equal to 4 quarts. Therefore, the price per quart is,

Price per quart  = $58/(4×2) = $7.25 per quart

Use this formula to
find the following values of the function:

F(a/2)
F(x-1)

F(x+h)

Answers

Answer:

F(2x+3) = 12/(2x+3) +1/2

Step-by-step explanation:

Put the argument of the function where the variable is. You can simplify if you want, but the original function definition is not simplified, so we assume it is not required.

F(x) = 12/x + 1/2

Put (2x+3) where x is:

F(2x+3) = 12/(2x+3) + 1/2

A Ferris wheel has a radius of 50 feet, and its center is 60 feet off the ground. How many points on the Ferris wheel are: 30 feet off the ground?

The answer is 6

The number of points are:

2 points for 30 feet off the ground. 1 points for 110 feet off the ground. 0 points for 5 feet off the ground.What is Circumference?

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.

Circumference (or) perimeter of circle = 2πR

A Ferris wheel has a radius of 50 feet, and its center is 60 feet off the ground.

So, DA = r = 50 feet

OB = 30 feet

<AOC = 2 <AOB

          = 2 x arc sin (4/5)

and, Circumference = 2πr = 100π

Then, AC = (2π - 2 arc sin (4/5)) . 50

Let there are total p points

So, A= (1- arcsin (4/5)/π )p

Thus, 2 points for 30 feet off the ground.

and, 1 points for 110 feet off the ground.

and, 0 points for 5 feet off the ground.

The probability as a fraction is 5/11

============================================================

Explanation:

There are 250 red and 300 blue. This gives 250+300 = 550 total marbles.

Divide the number of red (250) over the number total (550) to get the fraction 250/550. Reduce this fraction by dividing both parts by 50. Note how 50 is the GCF of 250 and 550.

Let A = 250 and B = 550.

A/GCF = 250/GCF = 250/50 = 5 which is the numerator already written for usB/GCF = 550/50 = 11 will go in the blank in the denominator

The fraction A/B = 250/550 fully reduces to 5/11.

We can think of it like saying "There are 5 red marbles out of 11 total".

5/11 = 0.4545 = 45.45% approximately
