Answer:
Ex1. X=-1
Ex2. 3rd choice
Step-by-step explanation:
Ex1. The only discontinuity in the domain is x=-1
Ex2. You just add values of x to those options and see which one applies
By the graph of a straight line through the origin with a slope equal to the unit rate
Answer:
g(a+1)=5a+2
Step-by-step explanation:
so (a+1) is the value of x
you can write it like this:
x=a+1
using substitution, we can swap out all 'x's for 'a+1's. like so;
g(a+1)=5(a+1)-3 -- given
=5a+5-3 -- distribute
=5a+2 -- simplify!
Hope i helped! have a great day! please mark brainliest!!
Answer:
3
Step-by-step explanation:
f(1)=−3
f(n)=2⋅f(n−1)+1
f(2)= 2×1(2-1)+1
= 2×1+1
= 2+1
= 3
Area = π r²
area of the required sector = (80/360) π * 15²
≈ 157.08
