Answer:

6 years

Step-by-step explanation:

Given

Initial\ Investment = 150

Ratio = double

Required

When will it get to 4000

This question illustrates a geometric progression and will be solved using:

T_n  = ar^{n-1}

In this case;

T_n = 4000

r = double = 2

a = 150

So, we're to solve for n

4000 = 150 * 2^{n - 1}

Divide through by 150

\frac{4000}{150} = 2^{n-1}

26.67= 2^{n-1}

Take Log of both sides

Log26.67= Log2^{n-1}

Apply law of logarithm

Log26.67= ({n-1})Log2

Take Log values

1.42602301569 = (n  - 1) * 0.30102999566

Make n - 1 the subject

n - 1 = \frac{1.42602301569}{0.30102999566}

n - 1 = 4.73714591984

Add 2 to both sides

n = 1 + 4.73714591984

n = 5.73714591984

n = 6 (Approximated)

<em>Hence, it'll take 6 years</em>

What is the y coordinate of the point that divides the
svet-max [94.6K]

Answer:

the y coordinate is 5

Step-by-step explanation:

In the figure attached, the  directed line segment is shown.

J is located at (-3, 1) and K is located at (-8, 11)

run: x2 -x1 = -8 - (-3) = -5

rise: y2 - y1 = 11 - 1 = 10

Taking J as reference, the coordinate of the point that divides the  directed line segment from J to k into a ratio of 2:3 is:

c = 2/(2+3) = 0.4

(x1 + c*run, y1 + c*rise)

(-3 + 0.4*-5, 1+0.4*10)

(-5, 5)
