Hey!
This could be rewritten as:
2x + 1 + 5x
We can add like terms together:
7x + 1
The numerator is 0, the denominator is -11, the division symbol is -, and the value of the fraction is 0 because the value of the numerator is 0
Answer:
Actually it's not polygon. it's a nonagon. With r=8.65mm″, the law of cosines gives us side a:
a=√{b²+c²−2bc×cos40°}
a=√{149.645−149.645cos40°}
Area Nonagon = (9/4)a²cos40°
=9/4[149.645−149.645cos40°]cot20°
=336.70125[1−cos(40°)]cot(20°)
Applying an identity for the cos(40°) does not get us very far…
= 336.70125[1−(cos2(20°)−1)]cot(20°)
= 336.70125[2−cos2(20°)]cot(20°)
= 336.70125[2−(1−sin2(20°))]cot(20°)
= 336.70125[1+sin2(20°)]cos(20°)sin(20°)
= 336.70125[cot(20°)+sin(20°)cos(20°)]mm²
Answer:
Step-by-step explanation:
<h3>Table 1</h3>
- x- values change 1 to 4
- y- values change inconsistently and repeat at -2
This is <u>not</u> a linear function
<h3>Table 2</h3>
- x- values change 1 to 4
- y- values change consistently, with common difference of -2
<u>This is a linear function</u>
<h3>Table 3</h3>
- x- values change 1 to 4
- y- values change inconsistently, the difference is not common
This is <u>not</u> a linear function
<h3>Table 4</h3>
- x- values change 1 to 4
- y- values change inconsistently, the difference is not common
This is <u>not</u> a linear function
