Answer:
Rate: 11%
Step-by-step explanation:
Interest formula.
Interest = Principal * Rate * Time
121 = 1100 * r * 1
Simplify equation to equal 121/1100 = r
There the rate is equal to 121 divided by 1100 which is 0.11.
To get the percent multiply my 100.
There the rate is 11%.
Proof:
1100 * 11 percent is equal to $121.
A. A negative times a negative is a positive
Answer:
4 · 1/4 (I-0) = (A-0)∧2
see details in the graph
Step-by-step explanation:
Matrix A is expressed in the form A∧2=I
To proof that Matrix A is both orthogonal and involutory, if and only if A is symmetric is shown by re-expressing that
A∧2=I in the standard form
4 · 1/4 (I-0) = (A-0)∧2
Re-expressing
A∧2 = I as a graphical element plotted on the graph
X∧2=I
The orthogonality is shown in the graphical plot displayed in the picture. Orthogonality expresses the mutually independent form of two vectors expressed in their perpendicularity.
Answer:
Step-by-step explanation:
x+5y=-27
-2x-5y=24
If the signs are the same u minus if they are different u add
So they are different were gonna add
x+5y=-27
-2x-5y=24
-1=-3
You cant divide it further x=-3
Next were gonna subsitute in any equation
x(-3)+5y=-27
-3+5y=-27
+3 to -27
-7+3=-24
5y=24
24/5=4.8 y=4.8
I hope this helps.
