You need to put the 15 over 1 and multiply 6 by 3 to get 18, which would be added to 2 to get 20/3, which you flip in order to get 3/20. You multiply the 15 by the 3 and the 1 by the 20 to get 45/20. You then simplify to get 2 1/4

The function. In the graph is f(x) =
Tanya [424]

Answer:

x^3-2x^2-5x+6

Step-by-step explanation:

We have been given a graph of the function f(x).

Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:

x^4-2x^2+5x+6

x^3-2x^2-5x+6

x^3-2x^2+5x+6

-x^4-2x^2+5x+6

We see that graph has end points in opposite direction then the degree of polynomial must be ODD.

Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.

Only x^3-2x^2-5x+6 satisfies the given points from graph.

Hence correct choice is x^3-2x^2-5x+6.

Use the remainder theorem to find the remainder of 2x^4 + x^2 - 10x -1 divided by x +2.
Svetllana [295]

Remainder Theorem says that if there is any Polynomial equation P(x), which is to be divided by (x - a) then remainder can be calculated by substituting value of a in equation P(x).  

2x^{4} +x^{2}-10x-1 = P(x)   divided by   (x+2)

Step 1: Find a

To find a we will have to convert (x+2) into (x - a) form

i.e.  (x+2) = (x - (-2))

therefore, a = -2

Step 2: Substitute value of a in P(x),

By substitution we get,

2(-2)^{4}+(-2)^{2}-10(-2)-1

= 2(16) + 4 +20 -1

= 32 +4 + 20 - 1

= 55 = Remainder

Hence, Remainder is 55.

Find The Slope &amp;&amp; Y-Intercept Of The Graph ...<br><br>Y = 6x + 11
Licemer1 [7]
The slope is the term that follows the x, so...

\boxed{\boxed{slope=6}}

now, the interception of Y happens when the X is equal 0, then...

y=6x+11

y=6*0+11

\boxed{\boxed{y=11}}

Below are 36 sorted ages of an acting award winner. Find P80.
blsea [12.9K]
P80 = 36 * 0.80 = 28.8

The above equation shows that the 80th percentile will have 28.8 values below it. So obtaining the 29th value will be the 80th percentile. 

Looking at the given values, P80 = 67.

Find the area of a quarter circle with the radius of 6cm
Ronch [10]

Answer:

28.27cm³

Step-by-step explanation:

Area of a circle:

A=\pi r^2

First, find the area of a full circle with this given radius:

\rightarrow A=(3.14159)(6)^2\\\rightarrow A=(3.14159)(36)\\\rightarrow A=113.09734\\

Now, to find the radius of a quarter circle with the same radius, just divide by 4:

\rightarrow A = \frac{113.09734}{4}\\\rightarrow A = 28.27433

The radius of the quarter circle is about 28.27cm³
