Set the function equal to zero and solve for x. 0=x^2+4x+12 factors to 0=(x-2)(x+6) which gives you intercepts of x=2 or -6.
Answer:
AB = 10, BC = 10
Step-by-step explanation:
AB = length of segment AB = sqrt( (-3-5)^2 + (-4-2)^2 ) = sqrt( 64 + 36) = sqrt(100) = 10
BC = sqrt( (5-11)^2 + (2-(-6))^2 ) = sqrt( 36 + 64 ) = sqrt( 100 ) = 10
I would say y = ln x + 4
you can use a graphing calculator
The cable should be 50 feet.
If you draw the picture, you will see that you have a right triangle.
Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).
30^2 + 40^2 = c^2
2500 = c^2
50 = c
15) Answer is B because you can clearly see it's only 1 inch
