Sinhx = 8/15 what are the other hyperbolic functions?

Answers

Answer 1

Answer: cosh^2x - sinh^2x = 1

coshx = sqrt( 1 + sinh^2x)

= sqrt(1 + (8/15)^2) = 17/15

for tanh

just divide

sinhx/coshx = tanhx = 8/17

for sech , cosech, coth << just flip the original as normal trigonometric functions

Answers

$2x+3y=12\n3y=-2x+12\ /\ :\ 3\ny=-\frac23x+4\na=-\frac23$

1.

$6y-4x=2\n6y=4x+2\ /\ : 6\ny=\frac23x+\frac13\na=\frac23$

2.

$6y+4x=2\n6y=-4x+2\ /\ : 4\ny=-\frac23x+\frac13\na=-\frac23$

3.

$4x-6y=2\n-6y=-4x+2\ /\ : (-6)\ny=\frac23x-\frac13\na=\frac23$

4.

$6x+4y=-2\n4y=-6x-2\ /\ : 4\ny=-1,5x-0,5\na=-1,5$

Step-by-step explanation:

Each time Jenny presses the tab key on the keyboard, the software reflects the logo she is designing across the x axis. Her cat steps on the tab key 25 times. In which quadrant does the logo end up. Explain.So that's all there is sorry if it's not clear but's its word for word

Answers

lol where do teachers find these types of problems XD
all jokes aside, let me explain.
so quadrants are numbered like this:
Top right:1
top left:2
bottom left:3
bottom right:4

and when you reflect something across an axis, it ends up in the quadrant opposite what it was in before. so If the logo is in quadrant 1 its first reflection will end up in quadrant 4. repeat and it will end up in quadrant one again. in other words if the number of times the tab key is hit is even, it will stay in the same quadrant. If it is odd it will end up in the quadrant opposite it. Since no quadrant number is given in the question we must assume that it just wants us to say whether it stays in the same quadrant or the one opposite it. In this case, because of what I said before, it would be in whatever quadrant was opposite the one it started in. Very badly worded question, but this is the only answer possible. Hope this helped! :) If you are still confused than just comment and I will try to help you out more.

a pastry recipe calls for 3 cups of flour to make 8 serving .how many cups of flour are needed to make 6 serving

Answers

If you would like to know how many cups of flour are needed to make 6 servings, you can calculate this using the following steps:

3 cups of flour ... 8 servings
x cups of flour = ? ... 6 servings

3 * 6 = 8 * x
18 = 8 * x /8
x = 18/8
x = 9/4
x = 2 1/4 cups of flour

The correct result would be 2 1/4 cups of flour.
