Answer:

b= -33

Step-by-step explanation:

b-38= -71

to isolate b, you have to add 38 to both sides

b= -71+38

b= -33

Answer:

b = -33

Step-by-step explanation:

Step 1: Add 38 to both sides

b - 38 = -71

b - 38 + 38 = -71 + 38

b = -33

Eli invested $ 330 $330 in an account in the year 1999, and the value has been growing exponentially at a constant rate. The val

Cloud [144]

Answer:

The value of the account in the year 2009 will be $682.

Step-by-step explanation:

The acount's balance, in t years after 1999, can be modeled by the following equation.

$A(t) = Pe^{rt}$

In which A(t) is the amount after t years, P is the initial money deposited, and r is the rate of interest.

$330 in an account in the year 1999

This means that $P = 330$

$590 in the year 2007

2007 is 8 years after 1999, so P(8) = 590.

We use this to find r.

$A(t) = Pe^{rt}$

$590 = 330e^{8r}$

$e^{8r} = \frac{590}{330}$

$e^{8r} = 1.79$

Applying ln to both sides:

$\ln{e^{8r}} = \ln{1.79}$

$8r = \ln{1.79}$

$r = \frac{\ln{1.79}}{8}$

$r = 0.0726$

Determine the value of the account, to the nearest dollar, in the year 2009.

2009 is 10 years after 1999, so this is A(10).

$A(t) = 330e^{0.0726t}$

$A(10) = 330e^{0.0726*10} = 682$

The value of the account in the year 2009 will be $682.

write an equation in slope intercept form of the line with a slope- 2 and y intercept 3. Graph the line

charle [14.2K]

Answer:

y = -2x + 3

Step-by-step explanation:

Step 1: Find out what each part of slope intercept form is

Slope Intercept Form: y = mx + b

m is the slope

b is the y-intercept

Step 2: Plug in the information into the formula

m/slope = -2

b/y-int = 3

y = -2x + 3

Answer: y = -2x + 3

Given the following sequence, find the 23rd term: 10.5, 11, 11.5, 12, 12.5, . . .

4vir4ik [10]

10.5, 11, 11.5, 12, 12.5...this is an arithmetic sequence with a common difference of 0.5

an = a1 + (n - 1) * d
n = term to find = 23
a1 = first term = 10.5
d = common difference = 0.5

sub and solve

a(23) = 10.5 + (23 - 1) * 0.5
a(23) = 10.5 + 22 * 0.5
a(23) = 10.5 + 11
a(23) = 21.5 <===
