Is this a right triangle or not?  If it's a right triangle, you could use the Pythagorean Theorem to find the length of the 3rd side, which would be the hypotenuse.  Thus, 14^2 + 4^2 = c^2, where c is the length of the hypot.

Then                        196 + 16 = 212, and this is c^2.  Then c, the length of the hypotenuse, is sqrt 212, or approx. 14.6 inches.

This does not agree with any of the four possible answers.  Thus, you must look at each of these possible answers and eliminate any that could not be correct.

for example:  if you take 10 inches and add 4 inches, you get 14 inches.  The result would not be a triangle, but rather a straight line.  

Check out the others similarly.

Given f (x) = 6x + 2, find f (x + 3).
Dovator [93]

Answer:

6x+20

c.

Step-by-step explanation:

If f(x)=6x+2 and you are asked to find f(x+3), then you just replace all the x's in f(x)=6x+2 with (x+3).

Doing this gives you:

f(x)=6x+2        with new input (x+3) in place of out input (x)

f(x+3)=6(x+3)+2

f(x+3)=6x+18+2

f(x+3)=6x+20

The slope field for the differential equation dy/dx=(3y)/(xy+5x) will have vertical segments when
Inessa05 [86]

Answer:

E) x=0 or y=-5

Step-by-step explanation:

The slope field will have vertical segments when dy/dx is undefined, that is, dy/dx is a division by 0.

We have that

dy/dx=(3y)/(xy+5x)

So the slope field will have vertical segments when

xy + 5x = 0

x(y + 5) = 0

This is when x = 0 or y = -5.

So the correct answer is:

E) x=0 or y=-5
