Determine the slope of the line that has the following coordinates: (5, 9)(11, - 3)

AlladinOne [14]

Answer:

$x_1 = 5, x_2 =11, y_1 =9, y_2 = -3$

The slope can be founded with this formula:

$m =\frac{y_2 -y_1}{x_2 -x_1}$

And replacing we got:

$m =\frac{-3 -9}{11-5}= -2$

And the best answer for this case would be :

$m=-2$

Step-by-step explanation:

For this case we have the following two points given:

$x_1 = 5, x_2 =11, y_1 =9, y_2 = -3$

The slope can be founded with this formula:

$m =\frac{y_2 -y_1}{x_2 -x_1}$

And replacing we got:

$m =\frac{-3 -9}{11-5}= -2$

And the best answer for this case would be :

$m=-2$

If 2000 dollars is invested in a bank account at an interest rate of 6 percent per year, find the amount in the bank after 7 yea

AfilCa [17]

Answer:

$3007.26

Step-by-step explanation:

Step one:

given data

Principal= $2000

rate= 6%= 0.06

time= 7years

Required:

The final amount A

Step two:

the expression for the compound interest is

$A= P(1+r)^t$

substituting we have

$A= 2000(1+0.06)^7\\\\A= 2000(1.06)^7\\\\A=2000*1.50363\\\\A=3007.26$
