Answer:
True
Step-by-step explanation:
Given:
The equation is

To find:
The number of roots and discriminant of the given equation.
Solution:
We have,

The highest degree of given equation is 2. So, the number of roots is also 2.
It can be written as

Here,
.
Discriminant of the given equation is





Since discriminant is
, which is greater than 0, therefore, the given equation has two distinct real roots.
.....Jeremy did not make a good inference. The ratio is not in proportion to 2/15. The correct inference would be about 26 students who did not read any books in July. The sample might be biased since it was limited to those at the pool....
Answer:
8.86
Step-by-step explanation:
Im guessing you want the rectangles area
Finding circle area do radius times radius times 3.14 so 1 x 1 = 1 x 3.14 = 3.14
Rectangle area is length times width so 3 x 4 = 12 - 3.14 = 8.86
