An initial investment of $100 is now valued at $150. The annual interest rate is 5%, compounded continuously. The equation 100e0
nikitadnepr [17]

Answer:

8\ 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

we have  

t=?\ years\\ P=\$100\\A=\$150\\ r=0.05  

substitute in the formula above  

150=100(e)^{0.05*t}  

1.5=(e)^{0.05*t}  

Applying ln both sides

ln(1.5)=(0.05t)ln(e)  

ln(1.5)=(0.05t)  

t=ln(1.5)/(0.05)  

t=8\ years

Find the triangle of the following figure: A. 30cm2 B: 36cm2 C. 18cm2 D. 15cm2
hram777 [196]

Answer:

D. 15cm2

Step-by-step explanation:

To find the area of a triangle, you multiply the base (10cm) and height of the triangle (3cm) and divide that by 2. So 10×3=30. Then, you need to divide this by 2. Since 30 is an even number, you won't get a decimal. So 30/2=15. And dont forget your units!

Why can't a trapezoid have 4 obtuse angles
In-s [12.5K]
Hello there, and thank you for posting your question here on brainly.

A trapezoid is not possible to have for obtuse because it would look more like a diamond. Also, if it had 4 obtuse angles, it would have 6 sides.

Hope this helped!! ☺♥

Bow do I graph y less than or equal to -x squared - 5
scZoUnD [109]

You would first graph [ y <em>equal to</em> -x² - 5 ], then look at the IN-equality.
It describes any point that's either ON that line or UNDER it.

Every point on that graph is equal to it, and every point directly under that graph
is less than it.

So the solution to the IN-equality is the line (the upside down parabola)
AND every point that's directly under any point on the parabola.

It winds up looking like a gray shower curtain that's hanging from a parabola
and has no bottom edge.  Starting from the parabola, it keeps going infinitely
far down, because every point that's under the parabola, no matter how far under,
satisfies the inequality.
