Thomas invests $50,000 in an account that compounds interest continuously and earns 15%. How long will it take for his money to
WARRIOR [948]

Answer:

It will take about 7.3 years for his money to triple.

Step-by-step explanation:

Identify the variables in the formula.

A = 150,000

P = 50,000

r = 0.15

t = ?

A = Pe^rt

Substitute the values into the formula.

150,000 = 50,000e^0.15*t

Solve for t. Divide each side by 50,000.

3 = e^0.15*t

Take the natural log of each side.

ln 3 = ln e^0.15*t

Use the power property and then simplify.  

ln 3 = 0.15*t ln e

ln 3 = 0.15-t

Divide each side by 0.15.

(ln 3) /(0.15) = t

Approximate the answer.

t ≈ 7.3

Triangle ABC is reflected over the Y axis. what are the coordinates of the reflected triangle
Liula [17]
Original Coordinates: A(1, 3) B(4, 5) C(3, 1)

Now, It is reflected over y-axis, so the sign of their x-coordinate will change.,

It would be: A'(-1, 3) B'(-4, 5) C'(-3, 1)

Hope this helps!

the school chorus has 52 students, which represent 26% of the seventh graders. how many student are in the seventh grade?
Alisiya [41]
So the equation would be 52/x (x being the number of total number of 7th graders) and 26/100 (100 being 26% out of 100%). 
You do cross multiplying which would be 52/x = 26/100 ------ 5200 = 26x
You divided 26 by both sides. 
5200/26=200
There are 200 7th graders total.
