Roots of the given equation will be imaginary because it's discriminant is less than 0 and hence it'll yield imaginary solutions
D < 0
b² - 4ac < 0
4² - 4 ( 5 ) < 0
16 - 20 < 0
-4 < 0
Hence it's character is stated above

Answer:
-8
Step-by-step explanation:
substitute x with 3
-4(3) + 4
simplify (multiply)
-12+4
simplify
-8
Answer:
If n > 0, then n= 1
If n < 0, then n=n
If you could word this a bit differently, I might be able to help more, but this is what I'm getting from it. The way you worded it is a bit confusing.
Answer:84mph there and 42mph back
Step-by-step explanation:do 924 divided by 11 and 924 by 22
Answer:
230
Step-by-step explanation:
The scale factor is by what amount the bigger is bigger than smaller, or what amount the smaller is smaller than the bigger.
Now, we first have to use same units. Lets use cm.
We know 100 cm = 1 meter
For projection (big one):
10 meters by 4.6 meters, that, in cm would be:
10*100 = 1000 cm
4.6 * 100 = 460 cm
So, the projection is:
1000cm (long) by 460 cm (tall)
The T-Rex on lens is:
x cm (long) by 2 cm (tall)
So, the height is given for both, so we can see that
2cm in lens is to 460 cm in projector
The scale factor is:
460/2 = 230
That means the projected image is 230 times the real image
THe scale factor is 230
