Answer:
B. a = 4, b = -8, c = -3
Step-by-step explanation:
The quadratic equation given is:

The general form of a quadratic equation is given as:

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

Therefore, by comparing:
a = 4
b = -8
c = -3
The correct option is B
Answer:
Lateral area of cone=pi *r*l
where r is radius
l is slant hieght
and pi can be 22/7 or 3.14
Step-by-step explanation:
- therefore, lateral area= 3.14*6*10
- =31.4*6
- 188.6m^2
Answer:
It would take 336 seconds
Step-by-step explanation:
Set up as a proportion:
50 meters/21 seconds = 800 meters/x
Then we cross multiply to find the answer:
336 = x
Ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375
hence ,<span> there is a greater proportion of smokers in the second city than in the first.
