Explain how to write a quadratic equation given the following three points on the graph (5,31) (3,11) (0,11)
masha68 [24]

Given:

The graph of a quadratic function passes through the points (5,31) (3,11) (0,11).

To find:

The equation of the quadratic function.

Solution:

A quadratic function is defined as:

y=ax^2+bx+c            ...(i)

It is passes through the point (0,11). So, substitute x=0,y=11 in (i).

11=a(0)^2+b(0)+c

11=c

Putting c=11 in (i), we get

y=ax^2+bx+11               ...(ii)

The quadratic function passes through the point (5,31). So, substitute x=5,y=31 in (ii).

31=a(5)^2+b(5)+11

31-11=a(25)+5b

20=25a+5b

Divide both sides by 5.

4=5a+b                  ...(iii)

The quadratic function passes through the point (3,11). So, substitute x=3,y=11 in (ii).

11=a(3)^2+b(3)+11

11-11=a(9)+3b

0=9a+3b

Divide both sides by 3.

0=3a+b                 ...(iv)

Subtracting (iv) from (iii), we get

4-0=5a+b-3a-b

4=2a

\dfrac{4}{2}=a

2=a

Putting a=2 in (iv), we get

0=3(2)+b

0=6+b

-6=b

Putting a=2,b=-6 in (ii), we get

y=(2)x^2+(-6)x+11

y=2x^2-6x+11

Therefore, the required quadratic equation is y=2x^2-6x+11.

The prices for different lengths of ribbon sold at a fabric store are shown in the table.
PolarNik [594]

Answer:

B. This relationship represents a function because no length of ribbon has more than one price.

Step-by-step explanation:

A relation is considered as a function when there is exactly just one possible range value that any of the domain value can give. In order words, each domain value of a function cannot have more than one range value.

In the given table of values representing the length and price of ribbon, the domain includes all the set of lengths of the ribbon while the range is the set of the corresponding prices the lengths can cost.

Thus, each length given has exactly just one price. No particular length has more than one price. Therefore, we can consider this as a function.

AB is tangent to circle O. If AO=24 and BC=50, what is AB? <br> The diagram is not to scale.
Oksana_A [137]

Answer:

The correct option is 70

Step-by-step explanation:

It is a right triangle so we will use Pythagorean theorem to find AB:

We have One side = 24 and hypotenuse = 24+50 which is 74

Now apply Pythagorean theorem:

AB = √(74)²-(24)²

AB = √5476-576

AB= √4900

Take the square root of 4900.

AB= 70

Thus the correct option is 70....
