Answer:
1 and 3 are both perpendicular to segment NY
Step-by-step explanation:
1. Find the slope of line NY
slope of NY = 5-(-7)/-11-5 = - 3/4
Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.
2.Find the slope of perpendicular lines
the inverse of negative slope of NY = - (-4/3) = 4/3
Answer: None of the above are correct.
Step-by-step explanation:
Given function: ![y=\tan x](https://tex.z-dn.net/?f=y%3D%5Ctan%20x)
We know that the value of tan x =0 at x=0.
Also, ![At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{3}=\sqrt{3}](https://tex.z-dn.net/?f=At%5C%20x%3D%5Cfrac%7B%5Cpi%7D%7B3%7D%2C%5C%20%5Ctan%5Cfrac%7B%5Cpi%7D%7B3%7D%3D%5Csqrt%7B3%7D)
![At\ x=\frac{\pi}{2},\ \tan\frac{\pi}{2}=\infty](https://tex.z-dn.net/?f=At%5C%20x%3D%5Cfrac%7B%5Cpi%7D%7B2%7D%2C%5C%20%5Ctan%5Cfrac%7B%5Cpi%7D%7B2%7D%3D%5Cinfty)
![At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{4}=1](https://tex.z-dn.net/?f=At%5C%20x%3D%5Cfrac%7B%5Cpi%7D%7B3%7D%2C%5C%20%5Ctan%5Cfrac%7B%5Cpi%7D%7B4%7D%3D1)
Hence, the only option is correct is "None of the above are correct".
Is this suppose to be for elementary because I'm in middle school and I got 900 2^2*3^2*5^2=900
Given:
First side(A): 2B - 7
Second side(B): B
Third side(C): B + 4
Plug in values:
A + B + C = 80
2B - 7 + B + B + 4 = 80
If you look at the coefficients only, you can rewrite the equation like this:
2B + B + B - 7 + 4 = 80
This means that 4B - 7 + 4 = 80
=4B - 3 = 80
= 4B = 80 + 3
B = 83/4, so you can either write B as 83/4 or as 20.75.
Checking your work:
A: 2(20.75) - 7 = 34.5
B: 20.75
C: 4 + 20.75 = 24.75
34.5 + 20.75 + 24.75 = 80cm.
Hope this helped.
