Answer:

The center of a circle is the point where we place the tip of our compass while drawing a circle. It is the mid-point of the diameter of the circle. In a circle, the distance between the center to any point on the circumference is always the same which is called the radius of the circle.

2. Solve for x. Round to the nearest hundredth if necessary.<br> Х<br> 19<br> 29°

marysya [2.9K]

Answer:

x ≈ 34.28

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan29° = $\frac{opposite}{adjacent}$ = $\frac{19}{x}$ ( multiply both sides by x )

x × tan29° = 19 ( divide both sides by tan29° )

x = $\frac{19}{tan29}$ ≈ 34.28 ( to the nearest hundredth )

PLEASE HELP!!! <br>What is the equation of the line graphed?

Sholpan [36]

Answer:

The equation of this line is y = 3x - 2

Step-by-step explanation:

In order to find this, start by finding two points on the line. We'll use (0,-2) and (1, 1). From there we start by finding the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (1 - -2)/(1 - 0)

m = (1 + 2)/(1)

m = 3/1

m = 3

Now using that, we can plug it, along with a point into point-slope form to get the answer.

y - y1 = m(x - x1)

y - 1 = 3(x - 1)

y - 1 = 3x - 3

y = 3x - 2

Mary is twice as old as her brother Zane.Zane is four years less than twice as old as his cousin chase.If chase is 4 years old,h

zzz [600]

Answer:

Mary is 8 and that Zane and Chase are both 4 years old.

Step-by-step explanation:

For this equation, we will say Mary = M, Zane = Z, and Chase = C.

We will now convert the word problem into equations.

$2m = z, 2c - 4 = z, c = 4$

Now I will solve the equations by putting C into the equation.

$2(4) = 8, 2(4) - 4 = 4, c = 4$

So we can see that Mary is 8 and that Zane and Chase are both 4 years old.
