What is the advantage of using function notation instead of using y?

1 answer:

6 0

The advantage of using function notation is that you can see the input and the output in the answer. For Example: if f(x)=2x + 1 then f(3)=7

Answer:

Scale factor = 2

Step-by-step explanation:

Scale factors deal multiplication. So, you would need to find a number to multiply by 6 to get 12. You can do this by doing 12 / 6.

12 / 6 = 2

What is the formula for the sum of the interior angles of a polygon

andrey2020 [161]

Answer:

Sum of the interior angles = (n-2) x 180°

where

n is the number of sides of the polygon

Step-by-step explanation:

The formula for the sum of the interior angles of a polygon is:

$sum=(n-2)*180$

where

$sum$ is the sum of the interior angle of the polygon

$n$ is the number of polygons

Let's check the formula using an example:

We want to find the sum of the interior angles of a square, we know that a square has 4 sides, so $n=4$ .

Replacing values

$sum=(4-2)*180$

$sum=(2)*180$

$sum=360$

We can apply the same procedure to any convex polygon with n sides.

a local high schools cheerleading squad is selling snow cones during lunch to raise money for a national cheerleading competitio

svlad2 [7]

We have:

Volume of cone = 535 cm³ at the maximum
Height of cone= 8cm

We know the formula to find volume of cone is $\frac{1}{3} r^{2} \pi h$

We need to find the radius of the base of the cone
$535= \frac{\pi r^{2}8} {3}$
$535*8= \pi r^{2}$
$\frac{4280}{\pi}= r^{2}$
$r= \sqrt{ \frac{4280}{ \pi} }$
$r=36.9$ to the nearest one decimal place

The width of the opening of the cone is the diameter of the circle. Diameter is twice the radius, hence 2×36.9=73.8 cm
