Helpppppp Two points defining a linear function are shown in the table below.

storchak [24]

A linear function is a function that creates a completely straight line. If we use the rise over run formula (x/y), we can see that when x goes up 4, y goes up 6. 4/6 simplified is equal to 2/3, so the slope is 2/3.

the area formula is a parallelogram is equal to (Base)*(height). If the area if a parallelogram is given by the trinomial x^2-14

abruzzese [7]

Answer:

x-12

Step by step explanation:

Here it is given that the area of a parallelogram is given by base * height. And if the area is represented by ,

$\longrightarrow A = x^2-14x+24$

And the base of the parallelogram is given by,

$\longrightarrow Base = x-2$

Substituting the values in the given formula, we have;

$\longrightarrow Area = base \times height$

$\longrightarrow x^2-14x+24=h(x-2)\\$

Divide both sides by (x-2) .

$\longrightarrow h =\dfrac{x^2-14x+24}{x-2}$

Factorise the term in numerator,

$\longrightarrow h =\dfrac{x^2-12x-2x+24}{x-2}\\$

$\longrightarrow h =\dfrac{x(x-12)-2(x-12)}{x-2}\\$

$\longrightarrow h =\dfrac{(x-2)(x-12)}{x-2}$

Simplify,

$\longrightarrow \underline{\underline{ height= x-12}}$

This is the required answer!

a circle with a radius of 3 has a sector with a central angle of 1/9 pi radians. What is the area of the sector?

Iteru [2.4K]

Answer:

The area of the sector is $\frac{\pi}{2}\ units^2$

Step-by-step explanation:

step 1

Find the area of complete circle

$A=\pi r^2$

we have

$r=3\ units$

substitute

$A=\pi 3^2$

$A=9\pi\ units^2$

step 2

Find the area of the sector

we know that

The area of complete circle subtends a central angle of 2π radians

using proportion

Find out the area of a sector by a central angle of 1/9 pi radians

$\frac{9\pi}{2\pi}=\frac{x}{\frac{1}{9}\pi} \\\\x=9\pi(\frac{1}{9}\pi})/2\pi\\\\x=\frac{\pi}{2}\ units^2$
