12.04

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\$

From the question we have

$d = \sqrt{ ({ - 9 - - 10})^{2} + ({1 - - 11})^{2} } \\ = \sqrt{ ({ - 9 + 10})^{2} + ({1 + 11})^{2} } \\ = \sqrt{ {1}^{2} + {12}^{2} } \\ = \sqrt{1 + 144} \\ = \sqrt{145} \: \: \: \: \: \: \: \: \\ = 12.041594$

We have the final answer as

12.04 to the nearest hundredth

Hope this helps you

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.
