2s+5≥49

First: Subtract 5 on both sides
You'll get: 2s ≥ 44
Last: Divide each side by 2 so your s would be alone
You'll get: s ≥ 22 <That would be your answer

HOPE THIS HELPS! ^_^

The table shows the results of an experiment in which subjects taking either a drug or a placebo either reported fatigue or did

Angelina_Jolie [31]

Answer:

- more subjects took the drug than took the placebo.

- a greater percent of the subjects did not report fatigue.

- a greater percentage of subjects taking the placebo did not report fatigue.

Step-by-step explanation:

60% of the subjects took the drug and 40% took the placebo.

56% of the subjects did not report fatigue and 44% reported fatigue.

28% of subjects taking the placebo did not report fatigue and 12% report fatigue.

The equation of a circle is ( x - 3) 2 + ( y + 2) 2 = 25. The point (8, -2) is on the circle.

Shtirlitz [24]

Answer:

x =8 is the equation of the tangent.

Step-by-step explanation:

Here the equation of the given circle is: $(x-3)^{2} + (y+2)^{2} = 25$

Now, comparing it with the general equation of circle: $(x-h)^{2} + (y -k)^{2} = r^2$

we get the central coordinates (h,k) = (3,-2)

So, the slope of the line joining center and (8, -2) = $\frac{-2 -(-2)}{8-3} = \frac{0}{5} = 0$

Since the slope of line = 0, line is parallel to x axis.

Now, as tangent and the line is perpendicular to each other

⇒Slope of the tangent = -1/ slope of the line = $\frac{-1}{0}$

Now, by point slope formula: the equation of the tangent is

(y-y0) = m (x-x0)

or, $(y +2) = \frac{-1}{0} (x -8)$

or x =8 is the equation of the tangent.
