let's recall the vertical line test, <u>for a function, if we run a vertical line anywhere it, it'll touch it only once</u>. is that true for a horizontal line? yeap.
Answer:
(a) 0.018 dm^3
(b) 20 x 10^15 ml^3
Step-by-step explanation:
a) 18 cm^3 to dm^3
1 cm = 0.1 dm
So,
1 cm^3 = 0.001 dm^3
So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3
b) 20 hl^3 to ml^3
1 hl = 100000 ml
So, 1 hl^3 = 10^15 ml^3
So,
20 hl^3 = 20 x 10^15 ml^3.
The factors of 32 are 1, 2, 4, 8, 16, and 32.
The factors of 20 are 1, 2, 4, 5, 10, and 20.
The common factors of 32 and 20 are 1, 2, and 4.
The greatest one is 4.
32 = 4 x 8
20 = 4 x 5
32 + 20 = (4 x 8) + (4 x 5)
32 + 20 = <em>4 (8 + 5)</em>
This is what I got, but you might want to double check me because I'm not that good at math (this is what I got for the discontinuity);
1. f(x)= x^2+6+8/x+4
*x+4=0
-4 -4
x= -4
This means that x cannot equal -4
2. f(x)= (x+2)(x-4)/(x+2)(x+2)
*Note: When I did my calculations, I cancelled out all (x+2) binomials except for one in the denominator*
f(x)= x-4/x+2
*x+2=0
-2 -2
x= -2
This means x cannot equal -2
*You may want to check my work, but I believe that your answer is going to be either C or D. Personally, I assume it's C, but that's just me. Anyway, it's probably going to be C or D, or at least that's what I think.*
The answer is D. 35. The x’s cancel out because x divided by x is 1 leaving you with 70/2 which is then 35.
Hope this helped.
