I believe the answer is they are drawing an Octagon because a polygon has 5 sides add that by three it's an Octagon
Use the Pythagorean Theorem: a^2 + b^2 = c^2
a and b are the measures of the legs and c is the measure of the hypotenuse
Let's solve for a (the length of the other leg)
<em>*I am hoping that m is not a variable and just an abbreviation for meters* </em>
b = 4 m
c = 6 m
a^2 + 4^2 = 6^2
a^2 + 16 = 36
a^2 = 20
a =
![\sqrt{20}](https://tex.z-dn.net/?f=%20%5Csqrt%7B20%7D%20)
<em>after simplifying...</em>
<em />a =
![2 \sqrt{5}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B5%7D%20)
m
Therefor we can conclude it is 2098 and we have made cheap and easy air travel.
Answer: C
Step-by-step explanation:
the equation for X is
use proportion to solve
2 + x = 16
x = 14
(14,y)
The equation for Y is
use proportion to solve
-1 + y = 6
y = 7
(14,7)
now use the distance formula
(14,7) (2,-1)
which gets you 14.4 or C
Answer: ![\bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}](https://tex.z-dn.net/?f=%5Cbold%7By%3D7cos%5Cbigg%28%5Cdfrac%7B2%5Cpi%7D%7B7%7Dx%5Cbigg%29%7D)
<u>Step-by-step explanation:</u>
y = A cos (Bx - C) + D
- A = amplitude (vertical stretch)
- Period = 2π/B
- C/B = phase shift
- D = vertical shift
The minimum is -7 and the max is 7 so A = 7 and D = 0
Period is 7. Since P = 2π/B then 7 = 2π/B --> B = 2π/7
Nothing was stated about a phase shift so you can use any value for C. I chose C = 0.
Now, input A = 7, B = 2π/7, C = 0, & D = 0 into the equation
![y=7\cos\bigg(\dfrac{2\pi}{7}x-0\bigg)+0\\\\\\\text{Simplify}:\\y=7\cos\bigg(\dfrac{2\pi}{7}x\bigg)](https://tex.z-dn.net/?f=y%3D7%5Ccos%5Cbigg%28%5Cdfrac%7B2%5Cpi%7D%7B7%7Dx-0%5Cbigg%29%2B0%5C%5C%5C%5C%5C%5C%5Ctext%7BSimplify%7D%3A%5C%5Cy%3D7%5Ccos%5Cbigg%28%5Cdfrac%7B2%5Cpi%7D%7B7%7Dx%5Cbigg%29)
