Yes it’s a rectangle because the diagonals bisect each other, and they are equal in length.
Yes, it’s a rectangle.

A rectangle is a four-sided flat shape where every angle is a right angle (90°). Opposite sides are parallel and of equal length (so it is a Parallelogram).

Answer:

y = 4x - 3

Step-by-step explanation:

The equation for a line is y = mx +c

We need to find m which is the gradient:

To do this pick any two coordinates on the line:

(1, 1) and (2, 5)

Next divide the difference of the y coordinates by the difference of the x coordinates:

5 - 1 / 2 - 1

= 4/1 = 4

so our gradient is 4

We'd write that as y = 4x + c

Next we need to find c which is the y-intercept

To do this just simply look for where the line crosses the y-axis

This is -3

So we'd write that as y = 4x - 3

Hope this helps :)

A skateboard ramp has a slope of 4/9. What is the measure of the angle the ramp forms with the ground

Answers

Answer:

Step-by-step explanation:

tanθ = 4/9

θ = arctan(4/9) ≈ 23.96°

The measure of the angle the ramp forms with the ground is :

-Angle is 23.96 degrees.

"Measure of the angle"

Let the angle is = x

We know that tan(x) is the slope.

tan(x)=\frac{4}{9}

tanθ = 4/9θ

tanθ = arctan(4/9)

tanθ≈ 23.96°

height of a cone is 30cm, its slant height is 32 cm, then the radius is- ?

Answers

Given:

Height of a cone is 30cm, its slant height is 34 cm.

To find:

The radius of the cone.

Solution:

Using the Pythagoras theorem, the relation between Height, radius and slant height is

[tex]r^2+h^2=l^2[/tex]

[tex]r^2=l^2-h^2[/tex]

Where, r is radius, h is height and l is the slant height.

Putting the given values, we get

[tex]r^2=(34)^2-(30)^2[/tex]

[tex]r^2=1156-900[/tex]

[tex]r^2=256[/tex]

Taking square root on both sides.

[tex]r=\pm\sqrt{256}[/tex]

[tex]r=\pm 16[/tex]

Radius cannot be negative. So, r=16 cm.

Therefore, the correct option is b.
