1) (12²)³ ₓ 12⁻⁴ = multiply exponents when you raise an exponent to an exp.
   12⁶ ₓ 12⁻⁴ = add
   12²

2) (12⁷ ₓ 12⁻⁵) / 12² = add the exponents up top
   12² / 12² = move all numbers to numerator and change signs
   12² ₓ 12⁻² = add the exponents

Complete this activity. Interest at the rates of 5%, 6%, and 8% is earned on investments of $13,000, $12,000, and $4,000 respect

zvonat [6]

The answer is 1690. First find the amount of interest by a single investment by multiplying the investment amount by the percent interest in decimal form. Then calculate the total by adding up all the products of investment times interest. Matrices will allow to multiply two things together and add the products up all at the same time. So we need to find the investment matrix and interest matrix.

Investment matrix A (transposed) = (a1 a2 a3) = (13,000 12,000 4,000)

Interest Matrix B = (b1 b2 b3) = (0.05 0.06 0.08)

Amount of interest earned = a1b1 + a2b2 + a3b3

Amount of interest earned = (0.05) (13,000) + (0.06) (12,000) + (0.08)(4,000)

Amount of interest earned = 1690

Henry knows that the circumference of a circle is 18mc006-1.jpg inches. What is the area of the circle?

lesantik [10]

The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?

Solution:
Circumference (C) of the circle can be written as:

$C=2 \pi r \\ \\ 18 \pi =2 \pi r \\ \\ r=9$

Using this value of radius, we can find the Area(A) of the circle.

$A= \pi r^{2} \\ \\ 
A= \pi (9)^{2} \\ \\ 
A=81 \pi$

Therefore, area of the circle having a circumference of 18π inches will be 81π inches²
