How much money has to be invested at 2.9% interest compounded continuosly to have 34,000 after 18 years
navik [9.2K]

Answer:

\$20,173.31  

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

we have  

t=18\ years\\ A=\$34,000\\ r=0.029  

substitute in the formula above  

34,000=P(e)^{0.029*18}  

P=34,000/((e)^{0.029*18})=\$20,173.31

Find the value of x
erik [133]

Answer:

x= 1.74

Step-by-step explanation:

Area of triangle= ½ ×base ×height

We are given that the base is (x +4), the height is x and the area is 5.

5= ½(x +4)(x)

Multiply both sides by 2:

x(x +4)= 10

Expand:

x² +4x= 10

x² +4x -10= 0

Let's use the quadratic formula!

\boxed{x =  \frac{ - b± \sqrt{ {b}^{2}  - 4ac} }{2a} }

x =  \frac{ - 4± \sqrt{ {4}^{2}  - 4(1)( - 10)} }{2(1)}

x =  \frac{ - 4± \sqrt{56} }{2}

x= 1.74 or x= -5.74 (reject)

(nearest hundredth)
