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
In synthetic division, you start by bringing down the first 1 in the box. Multiply that by the 1 outside the box and get a 1. Put that new 1 under the 2 inside the box and add to get 3. Multiply the outside the box by that 3 to get 3 and put that new 3 under the -3 in the box and add to get 0. Multiply that 0 by the 1 outside the box to get 0. Put that 0 under the 2 and add to get the remainder of 2. Your answer is 2, C.
Answer:
The diameter of the circle = 10 cm
The radius of the circle= 10/2= 5 cm
Step-by-step explanation:
Area of the circle = pi r^2
= pi 5^2
=3.14 *25
= 78.5 cm ^2
The variable x always equals 1
Answer: h(-4)
Step-by-step explanation:
If h(x) something is equal to 4 then set the equation equal 4 and solve for t.
4t +20 = 4
-20 -20
4t = -16
t = -4
So h(-4) = 4
