Hi Melody,
Thank you very much for your help :)
+7? no clue
arigato gaburiera-chan
I did Sin(300 in my calculator and got
-0.8660254038 no clue if I am right (still in 8th grade)
0.75 times 0.75 = 0.5625 or in other words 9/16 (nine over sixteen) five star if I helped!
4cos^2ϴ = 0 divide both sides by 4
cos^2ϴ = 0 take the sq rt of both sides
cosϴ = 0 at 90° and 270°
22,278 =2.2278 x 104
3x = 2y+14 (1)
y = -6x+18 (2) sub (2) into (1)
3x = 2 ( -6x+18 ) + 14
3x = - 12x + 36 + 14
3x = - 12x + 50 add 12x to both sides
15x = 50 divide both sides by 15
x= 50/15 = 10/3
And
y = -6(10/3)+18 = - 20 + 18 = -2
s+h= fridge
stomach+hunger=fridge
3/5
1.75x
32^(P-2) = 8^(3P) equate bases
(2^5)^(P - 2) = (2^3)^(3P)
2^(5P - 10) = 2^(9P) ...... so ......
5P - 10 = 9P subtract 5P from both sides
- 10 = 4P divide both sides by 10
-10/4 = P = - 5 / 2
tons of fun jus hangin' wid my buds
Rats !!!.....Melody beat me to it.....!!!!!
Re-arrange the first equation to get y = 9+x Substitute this in to the second equation
10 + 2x = -2(9+x) Solve for 'x'
10 + 2x = -18 - 2x add 2x to both sides of the equation
10 + 4x = -18 Subtract 10 from both sides
4x = -28
x = -7 (and y= 9+x = 2)
[9^(3k) * 27^(3k-1) * 3^k] / 81^(4k)
[ (3^2)^(3k) * (3^3)^(3k - 1) * 3^k] / [3^4]^{4k)
[ 3^(6k) * (3)^(9k - 3) * 3^k ] / [3^16]^k
[ 3^ ( 6k + 9k - 3 + k ) ] / [3^(16k)]
[ 3^(16k - 3) ] / [3^ (16k)]
3^(16k - 3 - 16k) =
3^( -3 )
1 / 27
Four :l
Two Because 50%(sale price) goes into 100% (original price) twice
40 % off means you are only paying 60% 60% of 80 = .6 x 80 = $ 48.
10 x log (10/5) = Approx 3db gain
There are three feet per yard so 7 yards = 7 x 3 = 21 feet so 7 yards < 50 feet
9^3k * 27^3k-1 * 3^k all divided by 81^4k like a fraction
\(\;\;\;\frac{9^{3k} * 27^{3k-1} * 3^k }{ 81^{4k} }\\ =\frac{3^{2*3k} * 3^{3(3k-1)} * 3^k }{ 3^{4*4k} }\\ =\frac{3^{6k} * 3^{9k-3} * 3^k }{ 3^{16k} }\\ =3^{6k+9k-3+k-16k}\\ =3^{-3}\\ =\frac{1}{3^3}\\ =\frac{1}{27}\)
what cphill said
[6^(2n)*36^(n+2)] / 216
[ (6^2)^n * (6^2)(n + 2)] / [36 * 6]
[ (6^2)^[n + n + 2] ] / [ 36^1 * 36^(1/2) ]
[ (6^2)^ [ 2n + 2] ] / 36^(3/2)
(36)^[2n + 2 - 3/2]
(36) ^ [ 2n + 1/2]
(6^2)^(2n + 1/2)
6^ (4n + 1)
@answer plz
it would be 5 gain
ummm its... 4 like are u in like grade 1 ?
