Answer:

Line segment U V is a secant Line segment X Y is a tangent and intersects the circle at point U

Step-by-step explanation:

The required, XY is tangent to Circle Z, as of the given condition.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.

Here,
From the diagram, we can use the Pythagorean theorem to justify whether XY is tangent to the circle Z, because if XY is the tangent then XYW is the right triangle.

So,
XY² = XW² + WY²

Substitute the value in the above expression,
16² = [2×6.4]² + 9.6²
256 = 256

Thus, XY is tangent to Circle Z.

Answer:

1/6

Step-by-step explanation:

Step-by-step explanation:

Given

In a circle

Radius (r) = 3 / 4 inches

Diameter (d)

= 2 * r

= 2 * 3 /4

= 3 /2 inches

Hope it will help :)❤

The diameter of a circle with a radius of 3/4 inches is 6/4 inches.

We are given that;

The radius of a circle = 3/4 inches

Now,

The diameter of a circle is twice the radius of the circle. Therefore, to find the diameter of a circle with a radius of 3/4 inches, we need to multiply 3/4 by 2. We can do this by multiplying the numerators and the denominators:

(3/4) x 2 = (3 x 2)/(4 x 2) = 6/8

We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:

6/8 = (6/2)/(8/2) = 6/4

Therefore, by the circle the answer will be 6/4.

Answer:

area = 520 units²

Step-by-step explanation:

divide the hexagon into 6 equal triangles.

each triangle has a base of 14 and a height of 12.1 so:

the area of one triangles = 1/2BH = 1/2(14)(12.1) = 86.8 units ²

86.8 x 6 triangles = 520.8 units²

Answer:

12mm (triangle)

165mm (whole shape)

Step-by-step explanation:

The triangle is 6 x 4 = 24 ÷ 2= 12

(divide by 2 because its a teiangle)

2nd shape is 10 x 8 = 80

3rd shape is 6 x 12 = 72

72 + 80 + 12 = 165mm

Answer:

B- Parallelogram PQRS is also a rhombus.

Step-by-step explanation:

Given

Parallelogram PQRS with perpendicular diagonals

Required

Which of the option is true

(a) PQRS can be a rectangle

A rectangle do not have perpendicular diagonals.

Hence, (a) is false

If (a) is false, then (d) is also false

(b) PQRS can a rhombus

The diagonals of a rhombus are not perpendicular.

So (b) is true

No need to check for (c), since only option is true

Answer:

B- Parallelogram PQRS is also a rhombus.

Answer:

Slope  = 3

y intercept = -8

y = 3x  - 8

Step-by-step explanation:

From the table shown, we can make use of the coordinate points

(0, -8) and (1, -5)

Slope m = y2-y1/x2-x1

m = -5-(-8)/1-0

m = -5+8/1-0

m = 3/1

m = 3

Slope  = 3

The standard form of an equation is y = mx+b

b is the y intercept

Substitute m = 3 and (0, -8) into y = mx+b

-8 = 3(0) + b

-8 = b

b = -8

Hence y intercept is -8

Get the required equation

Recall that y = mx+b

y = 3x + (-8)

y = 3x  - 8

This gives the required equation

if i know

Answer:

200.96

or

201 (if you round it up)

Step-by-step explanation:

1) Well, if we know that the diameter (D) is 16 cm, then we know that the radius (r) is 8 cm (D = 2 * r).

2) Next, we square (^2) the radius, and we get 64 (r^2 = r * r = 8*8 = 64)

3) Finally, we multiply π by 64, and we get 200.96 cm^2 (3.14 * 64) which is very close to 201 cm^2.
