Answer:
a) Arithmetic yₙ = 3*(n - 1) + 13
b) Geometric yₙ = 2*5⁽ⁿ⁻¹⁾
Step-by-step explanation:
Answer:
Length of QR = 7
Step-by-step explanation:
20 - 13 = 7
3x/7-2=15
3x/7 = 17
3x = 119
x = 39.67
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
Answer: Negative
Step-by-step explanation: Since the values of A and B are both negative (because they are below 0), adding them together will also make the sum negative.
