Answer:
AB
Step-by-step explanation:
A tangent is a line that touches a circle but never goes through it. Wherever the the tangent touches is called the point of tangency and creates a perpendicular bisector (90° angle).

Step-by-step explanation:
1. Let's calculate the unit price for each brand of diapers.
A. Stay-Dry: 108 diapers for US$ 25.18
Unit price = 25.18/108
<u>Unit price = US$ 0.23</u>
B. Uber-Soft: 180 diapers for US$ 39.14
Unit price = 39.14/180
<u>Unit price = US$ 0.22</u>
C. Cuddlies: 160 diapers for US$ 38.77
Unit price = 38.77/160
<u>Unit price = US$ 0.24</u>
<u>D. James should advise his mom to purchase Uber-Soft diapers, because the unit price is the lowest.</u>
Answer:
The probability that the time between two successive student arrivals at Benson is greater than 2 minutes is 0.000335.
Explanation:
The arrival rate of students is 4 students per minute.
The time between 2 successive arrivals is a random variable having exponential distribution.
The formula for exponential distribution is:
where L = Arrival rate of students (per minute) = 4
Hence,
We require the probability that the time between two successive arrivals is greater than 2 minutes. Therefore,
We are given the function <span>f(x) = 3^x+1 - 2 and is asked for the asymptote and y-intercept. In this case, we transform the function to
y +2 = 1/3^(x+1)-1
y = 1-2</span>/3^(x+1)-1/(3^(x+1)-1)
let 3^(x+1)-1 = 0
<span>1/3^(x+1) = 0
x = infinity
when x = infinity
y = 0 - 2
y = -2
The y-intercept is the value where x = 0. substituting,
y = 3^(0+1) - 2 = 1 </span>
2 ways to find the y int.
(1) put the equation in y = mx + b form and the y int will be in the b position
7x - 3y = -5
-3y = -7x - 5
y = 7/3x + 5/3....so 5/3 is ur y int
(2) another way is to sub in 0 for x and solve for y
7(0) - 3y = -5
-3y = -5
y = -5/-3
y = 5/3...ur y int
