A circle has a central angle measuring 7pi/6 radians that intersects an arc of length 18 cm. What is the length of the radius of

pochemuha

Α * R = L where L is the length of the arc of the circle, R is the radius of the circle, and α is the central angle measured in radians, so:

$\cfrac{7 \pi }{6}* R =18 \\ \\ 7*3.14* R=18*6 \\ \\ 21.98 R=108 \\ \\ R=108/21.98 \approx4.9 \ \text{cm}$

Determine the formula, in terms of x, that best describes the area of the plot.

liq [111]

The area of a plot is the amount of space on the plot

The area of the plot is 2x^2 -x - 1

<h3>How to determine the area</h3>

The dimensions of the plot are given as:

Length=2x+1

Width=x-1.

The area of the plot is the product of its dimension.

So, we have:

$Area = (2x + 1)(x - 1)$

Expand

$Area = 2x^2 - 2x + x - 1$

Evaluate the like terms

$Area = 2x^2 -x - 1$

Hence, the area of the plot is 2x^2 -x - 1

X+19=13 Find the value of x.

Oliga [24]

To find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-

x + 19 = 13
x = ?
13 - 19 = x
13 - 19 = -6
x = - 6

CHECK OUR WORK:-

x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!

So, x = -6

Hope I helped ya!! xD

Solve for y in terms of x.

krek1111 [17]

Answer:

$y=\frac{3}{2} x+6$

Step-by-step explanation:

We are given the following equation and we are supposed to solve y in terms of x. It simpler terms, it means that we have to make y the subject of the equation while x being used in it as it is:

$\frac{2}{3} y-4=x$

Taking the constant 4 to the side where x is to get:

$\frac{2}{3} y=x+4$

Multiplying the denominator 3 to the other side of the equation to get:

$2y=3x+12$

Isolating y to make it the subject:

$y=\frac{3}{2} x+\frac{12}{2}\\ \\y=\frac{3}{2} x+6$
