Step-by-step explanation:
At d, f'(x) is increasing (concave up), but it is not positive. The tangent line at that point has a negative slope.
Answer:
A 144
B no
Step-by-step explanation:
Decagon is a 10 sided figure
interior angle = 180 (n-2)/n where n=10
180*(10-2)/10
180*8/10
144
To tessellate, the angle must divide evenly into 360
360/144= 2.5
This is not evenly so it will not tessellate
Answer:
14
Step-by-step explanation:
right angle is equal to 90 so you just minus 76 from 90
