Answer:
good evening,
You should notice that :
n=4K or n=4K+1 or n=4K+2 or n=4K+3
If n=4k so n(n+1)(n+2)(n+3)is a multiple of 4
If n=4K+1 so n+3 =4(k+1) so n(n+1)(n+2)(n+3)is a multiple of 4
If n=4K+2 so n+2 =4(k+1) so n(n+1)(n+2)(n+3)is a multiple of 4
If n=4K+3 so n+1=4(k+1) so n(n+1)(n+2)(n+3)is a multiple of 4
:)
Memorize Soh Cah Toa, which means:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite & adjacent are determined based on the angle being referenced.
hypotenuse is ALWAYS opposite of the 90 degree angle.
sin Y = 12/13
cos Y = 5/13
tan Y = 12/5
Answer:
(-5,4)
Step-by-step explanation:
If you look at A and then at AB midpoint you will see that A is 5 down from M and 4 right from M. So, if you minus 4 from -1 you get -5, and if you add 5 from -1 you get 4. Therefor the answer is (-5,4)
Let's translate the words into expressions:
11 less than 7 times a number is
5 more than 6 times the number is
So we have the equation
Subtract 6x from both sides:
Add 11 to both sides:
.84(25)=21
84%=.84
So 84%of 24 is .84*25
