The inequality for the figure:
x > -30
-30 is not included because there's a hole circle upon number -30. -30 will be included if the circle doesn't have a hole. See the difference on image attached.

So the answer will be the numbers bigger than -30, they are: -10, 25, 0, 83 (ACDF)

What is the slope of the line tangent to the curve y+2 = (x^2/2) - 2siny at the point (2,0)?

kirza4 [7]

, y+2 = (x^2/2) - 2sin(y) so we are taking the derivative y in respect to x so we have dy/dx use chain rule on y so y' = 2x/2 - 2cos(y)*y'

Now rearrange it to solve for y' y' = 2x/2 - 2cos(y)*y' 0 = x - 2cos(y)y' - y' - x = 2cos(y)y' - y' -x = y'(2cos(y) - 1) -x/(2cos(y) - 1) = y'
we know when f(2) = 0 so thus y = 0 so when f'(2) = -2/(2cos(0)-1)
2/2 = 1
f'(2) = -2/(2cos(0)-1) cos(0) = 1 thus f'(2) = -2/(2(1)-1) = -2/-1 = 2 f'(2) = 2

Please make Y=x+12 and 4x+2y=27 into one equation.

tiny-mole [99]

So what you need to start with is taking the x from both sides as adding 12 to them. Then, you move the 27 over 4 decimals.

There are two sizes of red and blue marbles in a box. If the big marbles in the box, 45 are red and 3/4 are blue. The fraction o

Nat2105 [25]

Let
x------> amount of big marbles in the box
y------> amount of small marbles in the box
R----> amount of small marbles that are red in the box
B----> amount of small marbles that are blue in the box

we know that
x=45+(3/4)*x----> x-(3/4)*x=45----> x/4=45-----> x=180

R+B=y-----> equation 1
R=(2/5)*y---> equation 2
B=(3/5)*y---> equation 3
B=R+24----> equation 4

substitute equation 2 in equation 1
[(2/5)*y]+B=y----> equation 5

substitute equation 2 in equation 4
B=[(2/5)*y]+24----> equation 6

resolve the system
[(2/5)*y]+B=y---> multiply by 5----> 2y+5B=5y----> 3y=5B
B=[(2/5)*y]+24----> multiply by 5----> 5B=2y+120

using a graph tool
see the attached figure

the solution is
B=72
y=120
R=y-B----> R=48

total marbies=x+y-----> 180+120-----> 300
tota; big marbies=180
percent of the marbles are big marbles
if 100%-----------> 300
X----------------> 180
x=180*100/300-----> x=60%

the answer is
60%
