Answer:

y-1= -4(x+3)

Step-by-step explanation:

When finding point slope form, this is the format: y-y1=m(x-x1). First, plug in your coordinate to the equation. It should look like this: y-1=m(x+3). However, one thing you should know is if the coordinate is a negative, it becomes a positive in point slope form. Next, plug in the slope to the equation. This is your final answer: y-1= -4(x+3). Hope this helped!

The circumference of a pizza is about 38 inches. What is the diameter of the pizza? Round to the nearest tenth if necessary

anygoal [31]

Answer:

The diameter of the pizza is 12 inches

Step-by-step explanation:

Given:

Circumference of a pizza = 38 inches

To Find:

The Diameter of the pizza =?

Solution:

Circumference:

The distance around the edge of a circle (or any curvy shape). It is a type of perimeter.

We know that the shape of the pizza is circle.

So the given circumference is circumference of a circle.

Now,

Circumference of the circle(pizza)= $2\pi r$

where r is the radius of the circle

circumference of the pizza =38

Thus

$2\pi r= 38$

$\pi r=\frac{38}{2}$

$\pi r=19$

$r=\frac{19}{3.14}$

r=6.050 inches

Now,

Diameter = $2\times r$

Diameter = $2\times 6.05$

Diameter=12.1 inches

Rounding to the nearest tenth

Diameter=12 inches

The length of the hypotenuse of a 30° -60° -90° triangle is 4. Find the longer leg.

Oduvanchick [21]

longest leg = 2 $\sqrt{3}$

The longest leg is opposite the 60° angle

= 4 × sin60°

= 4 × $\sqrt{3}$ / 2 = 2 $\sqrt{3}$
