What is the trigonometric ratio for sin S?

Enter your answer, as a simplified fraction. 

f(-2) is negative, so use the x < 0 equation: 2(-2) = -4

f(-1) is also negative, so: 2(-1) = -2

f(0) goes with the x > 0 side, which would be: (0) + 7 = 7

f(1) and f(2) are the same as f(0), so it would be (1) + 7, (2) + 7

If f(x) = 3x - 8, then ... 

f(2x) = 3(2x) - 8

2f(x) = 2(3x - 8)

Yah....you are CORRECT.....had been thinking a bit about that....another answer soon..... bummer !   HaHa

4 out of the 64 are painted on two surfaces

  there are an additional 24 cubes are painted on one side   out of 64

        so 64 - (24+4) = 36 have no paint

EP, your solution method will not give the correct result. 

The performance times (contributions) of an individual worker is combined (buried) with the times of two (2) other individual workers. These individual times have to be extracted (separated) from the data before they are recombined for a collective result. 

Note that by doubling your result, the time will then be very close to the correct calculated time. This is because the times used in your calculation are based on two workers.

During a football match in a tournament a goalkeepers save rate was given as 33%. After saving the next shot on target it rose to 40%. How many more shots on target does he need to save to raise his save rate to 50%?   

                                           3 saves out of  9 shots is 33%. 

add 1 more save and  ...    4 saves out of 10 shots is 40%. 

add 2 more saves and  ...  6 saves out of 12 shots is 50%.

You should post each Q seperately with their own header.......but here is this one

M/L = 2/3

A.    4/L = 2/3   solve for L = 6 mi

B.   M/930 = 2/3    solve for M = 620 m

C.   4 : 6      620: 930    are equiv to  2:3

There are 8 + 4 + 8 + 6 = 26 such planes.

1) Angle AOB is 45 degrees.

2) Angle ABC is 120 degrees.

amountleft = amount (1-.5)ⁿ        Where n = number of half lifes     amount left = 1 - .76 = .24

.24 = (1-.5)ⁿ

.24 = .5ⁿ        Log both sides

log .24 = n log .5

log .24 / log .5 =  n

n = 2.0589 half lifes = 61.77 seconds

yes! thank you.:)

I think this?

9^x  + 3^1+2x  = 50

3^2x  + 3^1+2x

3^2x +3 * 3^2x

4* 3^2x  = 50

3^2x  = 50/4 = 12.5   take logs of both sides

2x log 3 = log 12.5

2x = log12.5/log3

x = 1.1495

Let's see how long it wil take them to build THREE walls....then divide the resulting time by 3

1/6  + 1/9  + 1/12  =  3/x

(12 + 8 + 6) / 72  = 3/x

26/72 = 3/x

x = 3 * 72/26    x = 8.30769   for THREE walls  

One wall = 2.7692 days

9^x+3 and everything past 3 is the exponent 1+2x is the exponent and it all equals 50. Find the exact solution of the exponential equation in terms of logarithms.

The maximum value of GCD of [11n +3] and [2n +1] = 5

Your equation is still a bit of a mess.....

Let the initial amount of A = A
Let the initial amount of B = B

A + B = 320
A =320 - B
B =320 - A

A =[320 - B] - 0.20[320 - B]
B =[320 - A] +0.20[320 - B]

B =[320 - A] + 0.20[320 - B] - 0.20 {[320 - A] + 0.20[320 - B]} = -0.8 (A + 0.2 B - 384.)

A =[320 - B] - 0.20[320 - B] + 0.20 {[320 - A] + 0.20[320 - B]} = 0.04 (-5 A - 21 B + 8320)

A = 100 dollars - A started with
B = 220 dollars - B started with
