Answer:

- 3 $x^{4}$ + 15x² - 3x

Step-by-step explanation:

Given

(5 $x^{4}$ - 3x + 8x²) - (8 $x^{4}$ - 7x²)

Remove the parenthesis on first and distribute second by - 1

= 5 $x^{4}$ - 3x + 8x² - 8 $x^{4}$ + 7x² ← collect like terms

= - 3 $x^{4}$ + 15x² - 3x ← in standard form

Answer:

Make sure you are using a perfect circle. This method won't work with ellipses, ovals or anything but a real circle. A circle is defined as all the points on a plane that are an equal distance from a single center point. The lids of jars are good household objects to use for this exercise.You should be able to calculate pi roughly because in order to get exact results of pi, you will need to ...

Measure the circumference of a circle as accurately as you can. The circumference is the length that goes around the entire edge of the circle. Since the circumference is round, it can be difficult to measure (that's why pi is so important). Lay a string over the circle as closely as you can. Mark the string off where it circles back around, and then measure the string length with a ruler.

Measure the diameter of the circle. The diameter runs from one side of the circle to the other through the circle's center point.

Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.[3] X Research source

Repeat this process with several different circles, and then average the results.

Given:

Measure of arcs 50°, 115° and 85°

To find:

The measure of the numbered angle 5.

Solution:

Let the missing arc measure be A.

The arc measure of a full circle is 360°

m(ar A) + 50° + 115° + 85° = 360°

m(ar A) + 250° = 360°

Subtract 250 from both sides.

m(ar A) = 110°

<em>If two chords intersects inside a circle, then the measure of the angle formed is half of the sum of intercepted arcs.</em>

$$\Rightarrow m\angle 5 =\frac{1}{2} (110^\circ+115^\circ)$

$$\Rightarrow m\angle 5 =\frac{1}{2} (225^\circ)$

$$\Rightarrow m\angle 5 =112.5^\circ$

The measure of the numbered angle is 112.5°.

Consider the function f(x) = x(x-4.

jeyben [28]

Step-by-step explanation:

point (c-2, y) lies on the graph of f(x)=x(x-4)f(x)=x(x−4) .

Step-by-step explanation:

Given function f(x)=x(x-4)f(x)=x(x−4) also point (2+ c,y) is on the graph of f(x) ,

We have to find out of given point which point will also be on the graph of f(x).

Consider the given function f(x)=x(x-4)f(x)=x(x−4)

f(x)=x(x-4)f(x)=x(x−4) can be rewritten f(x)=x^2-4xf(x)=x

−4x

Now we substitute the given point (2+ c, y) in the function given ,

we have,

f(x)=y=x(x-4)f(x)=y=x(x−4)

put for x as 2+c , we have,

\Rightarrow y=(2+c)(2+c-4)⇒y=(2+c)(2+c−4)

Solve, we get

\Rightarrow y=(2+c)(c-2)⇒y=(2+c)(c−2)

Thus, both point (2+c, y) and (c-2, y) lies on the graph of f(x)=x(x-4)f(x)=x(x−4)

Thus, option (1) is correct.
