Suppose you invest 1600 dollars at an annual interest rate of 4.6% compounded continuously how much will you have in the account
mezya [45]
Hello!

We will add up 0.046 of our number each year for four years as seen below.

1600(0.046)=73.6
1600+73.6=1673.6

1673.6(0.046)≈76.99
1673.6+76.99=1750.59

1750.59(0.046)≈80.53
1750.59+80.53=1831.12

1831.12(0.046)≈84.23
1831.12+84.23=1915.35

Therefore, you will have about $1,915.35 in your account after 4 years.

I hope this helps!

In the diagram, point P is a point of tangency. Find the radius r of circle O.​
vlabodo [156]

Answer:

r = 12

Step-by-step explanation:

From the figure attached,

QP is a tangent to the circle O at the point P.

Therefore, by the property of tangency,

OP ⊥ QP

By applying Pythagoras theorem In right triangle QPO,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

(OQ)² = (OP)² + (PQ)²

(25 + r)² = (35)² + r²

625 + r² + 50r = 1225 + r²

50r = 1225 - 625

50r = 600

r = 12

Therefore, r = 12 units is the answer.

nevsk [136]

Answer:

$1950

Step-by-step explanation:

Simple interest amount payable is given by

A=P(1+rt) where p is principal amount, A is final amount paid, t is time and r is rate of interest. For the first case

A=15000(1+0.03*4)=$16800

For second case

A=15000(1+0.05*5)=$18750

Difference will be 18750-16800=$1950
