How would you find the area in this regular polygon

Mathematics

This is a pentagon, with five equal central angles.  Each central angle is 360 degrees/5 = 72 degrees.

The pentagon has five pie-shaped pieces, each with an angle of 72 degrees and two other angles, which are equal, of 54 degrees.

The "base" of each such triangular (pie-shaped) pieces is 5.

Use this info to find the area of ONE of these pieces.

Then multiply your result by 5 to obtain the total area of this pentagon.

Varvara68 [4.7K]

Hello!

Let's solve this equation for y first.

-10x+y=4

Add 10x to both side.

y=10x+4

Now, let's plug in our x-values to find y.

x: -2, -1, 0, 1, 2

y:-16,-6, 4,14,24

I hope this helps!

100PTS PLS HURRY I ONLY HAVE 40 MINUTES Determine the common ratio and find the next three terms of the geometric sequence.
hammer [34]

Answer:

\Large \boxed{\mathrm{\bold{B.} \ -0.5 \ ; \ 0.875 \ , \ -0.4375 \ , \ 0.21875}}

Step-by-step explanation:

The common ratio can be found by finding the quotient of a term and the previous term in the sequence.

\displaystyle \frac{3.5}{-7} =-0.5

The common ratio is -0.5.

The rule is to multiply a term in the sequence by -0.5 to get the next term.

Next 3 terms :

-1.75 \times -0.5=0.875 \\\\ 0.875 \times -0.5 = -0.4375 \\\\ -0.4375 \times -0.5=0.21875

The next 3 terms are 0.875, -0.4375, 0.21875.

Evaluate fog and gof if f(x)=5x-8 and g(x)= x^3
DerKrebs [107]

Answer:

see explanation

Step-by-step explanation:

note that f ○ g = f(g(x))

To evaluate substitute x = x³ into f(x)

f(g(x)) = f(x³) = 5x³ - 8

In the same way

g ○ f = g(f(x))

To evaluate substitute x = 5x - 8 into g(x)

g(f(x)) = g(5x - 8) = (5x - 8)³
