Keegan deposited $700 into his bank account. After one year, his bank account balance was $761.60. What interest rate did he ear

ikadub [295]

Answer:

8.8%

Step-by-step explanation:

We first divide the new amount by the original and close it with brackets.

Our one year will be shown as 1/1 as an indices

(761.60/700)^1/1

= 1.088

We then convert it to 0.088 and times it by 100.

0.088×100= 8.8% Compound interest rate.

This is correct as:

700×1.088= 761.6

Have a nice day! :)

A company is trying to decide where to build a cell phone tower so that its signal will have the same strength in 3 towns. The l

r-ruslan [8.4K]

The position of the cell phone tower is an illustration of the triangle midpoint

The cell phone tower should be located at $(9, \frac 83)$

<h3>How to determine the coordinates of the cell phone tower </h3>

The coordinates are given as:

A(1, 1), B(13, 6), and C(13, 1)

The midpoint is then calculated as:

$(x,y) = \frac 13 * (x_1 + x_2 + x_2, y_1 + y_2 + y_3)$

So, we have:

$(x,y) = \frac 13 * (1 + 13+ 13, 1 + 6 +1)$

Evaluate the sum

$(x,y) = \frac 13 * (27, 8)$

Evaluate the product

$(x,y) = (9, \frac 83)$

Hence, the cell phone tower should be located at $(9, \frac 83)$
