It should be 10...because the 2 angles in the base are the same so the length is mirrored
Answer:
See below in bold.
Step-by-step explanation:
Total = A(1 + r/n)^nt where A = initial amount , t = number of years, r = the rate (as a decimal fraction) and n = number of payments a year. So:
Total after 1 year = 8000(1 + 0.09/2) ^ 1*2
= RS 8736.20.
Compound interest = RS 736.20
Answer:
Mean: 23. 54545455
Median: 22
Step-by-step explanation:
The median represents the center the most because when you are solving for the median, you look for the direct center of the terms which will be 22, the median.
G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
Count change of signs to tell positive roots
then replace x with -x and evaluate, then count change in sign for negative roots
initially
+, -, -, +, +, -
3 changes
3 or 1 positive roots
replacing x with -x
-,-,+,+,-,-
2 changes
2 or 0 negative roots
