Answer:

Step-by-step explanation:

y=mx+b

m=(y2-y1)/(x2-x1), (-6,3), (-5,2)

m=(3-2)/(-6+5)=-1

y=-x+b, using point (-6,3) we can solve for b

3=-(-6)+b

3=6+b

b=-3

y=-x-3

A woman invests $5800 in an account that pays 6% interest per year, compounded continuously.

mel-nik [20]

Answer:

Part a) $\$6,539.48$

Part b) $5.36\ years$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

Part a) What is the amount after 2 years?

we have

$t=2\ years\\ P=\$5,800\\ r=0.06$

substitute in the formula above

$A=\$5,800(e)^{0.06*2}=\$6,539.48$

Part b) How long will it take for the amount to be $8000?

we have

$t=?\ years\\ P=\$5,800\\ r=0.06\\A=\$8,000$

substitute in the formula above and solve for t

$\$8,000=\$5,800(e)^{0.06t}$

$(8,000/5,800)=(e)^{0.06t}$

Applying ln both sides

Remember that

ln(e)=1

$ln(8,000/5,800)=0.06t$

$t=ln(8,000/5,800)/0.06=5.36\ years$

Solve the equation. Write your answer as an integer or simplified fraction. 8n−9 n−2 =17 n=

Paul [167]

Answer:

n = - 19

Step-by-step explanation:

8n - 9n - 2 = 17 , that is

- n - 2 = 17 ( add 2 to both sides )

- n = 19 ( multiply both sides by - 1 )

n = - 19

What is the greatest common factor of 24s3, 12s4, and 18s? 3 6 3s 6s

Arte-miy333 [17]

Answer:

=> 6s

Step-by-step explanation:

Given terms

24s^3 ,12s^4 and 18s

GCF consists of the common factors from all the terms whose GCF has to be found.

In order to find GCF, factors of each term has to be made:

The factors of 24s^3:

24s^3=2*2*2*3*s*s*s

The factors of 12s^4:

12s^4=2*2*3*s*s*s*s

The factors of 18s:

18s=2*3*3*s

The common factors are(written in bold):

GCF=2*3*s

=6s

So the GCF is 6s ..
