Answer:

12.12%

Step-by-step explanation:

We have that the formula is given by:

A = p * e ^ (r * t)

From here, we know that A = 200000; p = 20000 and the time we can calculate 40 - 21 = 19

if we replace we have:

200000 = 20000 * e ^ (19 * r)

we must calculate r:

e ^ (19 * r) = 200000/20000

e ^ (19 * r) = 10

19 * r = ln 10

r = ln 10/19

r = 0.1212

In other words, the rate of growth is 12.12%

Y’all give me dis answer to
Leto [7]

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4     Eqn 1

4x+y = 1     Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3

Putting y = -3 in equation 1

x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1

Hence,

The solution is: (1,-3)
