The surface area will increase by a factor of 49/16
Answer:
Step-by-step explanation:
Here time (t) is the independent variable; power (p) is the dependent one.
The graph of p = 100 - 4t is a straight line with slope -4. 100 is the vertical intercept. Battery power begins at 100 and steadily decreases after that.
Answer:
Step-by-step explanation:
The inequality equation can be determined by using the concept of arithmetic progression;
a(n) = a₁ + (n-1)d
where;
a(n) = 1000
a = 200
d = 50
The inequality will be:
1000 = 200 + ( n - 1) 50
1000 = 200 + 50n - 50
1000 = 150 + 50 n
1000 - 150 = 50 n
850 = 50 n
n = 850/50
n = 17 months
So, if Ms. Thomas is planning to have more than $1000 in her account, she will need to save for 17 moths before she can buy the phone.
