Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $22 monthly fee

vladimir2022 [97]

Company a = 22 + 0.07m
company b = 8 + 0.12m

We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b

company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280

Therefore, the two companies will cost the same if you talk for 280 minutes

A countrys population in 1995 was 173 million in 1997 it was 178 million estamate the population in 2005 using the expontial gro

9966 [12]

Answer: the population in 2005 is

199393207

Step-by-step explanation:

The formula for exponential growth which is expressed as

A = P(1 + r/n)^ nt

Where

A represents the population after t years.

n represents the periodic interval at which growth is recorded.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 173 million

A = 178 million

t = 1997 - 1995 = 2 years

n = 1

Therefore

178 × 10^6 = 173 × 10^6(1 + r/1)^2 × 1

178 × 10^6/173 × 10^6 = (1 + r)^2

1.0289 = (1 + r)^2

Taking square root of both sides, it becomes

√1.0289 = √(1 + r)^2

1 + r = 1.0143

r = 1.0143 - 1 = 0.0143

Therefore, in 2005,

t = 2005 - 1995 = 10

A = 173 × 10^6(1 + 0.0143)^10

A = 173 × 10^6(1.0143)^10

A = 199393207

On a number line, suppose point E has a coordinate of 4, and EG = 11. What are the possible coordinates of point G?

navik [9.2K]

Answer:

-7, 15

Step-by-step explanation:

The positive difference between E and G is 11.

<h3>Solution</h3>

G - E = 11

G = 11 + E = 11 + 4

G = 15 . . . . . . . . . . . . . when G is right of E

__

E - G = 11

E - 11 = G = 4 - 11

G = -7 . . . . . . . . . . . . when G is left of E

Possible coordinates for G are -7 and 15.
