Answer:
The last one.
Step-by-step explanation:
Answer:
4 + x < 22
that's what the equation is
Step-by-step explanation:
a number just means a variable ex: x, y
at least is this : <
so 4 + x < 22
A) n(0) = 20 because n(0) = 20(2)^0 and anything to the power 0 is 1. The reason that any number to the zero power is 1 is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1
Thus, n(0) = 20(1) = 20. In terms of the situation, if 0 days have passed since Monday, 20 people know about the rumor.
b) n(-2) = 20(2)^-2 = 20* 1/(2^2)
=20/(2^2) = 20/4 = 5.
In terms of the situation, two days before Monday, 5 people know the rumor.
7^2 + 5^ 2 = 49 + 25 = 74
The answer is the last picture ( Purple triangle)
