Answer:
<u>3rd graph (on bottom left)</u>
Step-by-step explanation:
First, find the <u>zeros of the function</u>.
- f(x) = x² - x - 2
- f(x) = x² + x - 2x - 2
- f(x) = x(x + 1) - 2(x + 1)
- f(x) = (x - 2)(x + 1)
The zeros are :
- x - 2 = 0 ⇒ x = 2
- x + 1 = 0 ⇒ x = -1
Therefore, the graph of the function intersects the x-axis at :
The correct graph is <u>3rd graph (on bottom left)</u>
Answer:
If we split this figure into a rectangle and triangle, we can solve:
THe rectangle would have an area of 4.14 (a=b x h) and the triangle would have an area of 8.28 (a=1/2bh)
If we add these numbers together we should have the area
a=4.14+8.28
a=12.42
Step-by-step explanation:
Radii is defined as the line joining the centre of the circle to a point on the circumference
as there are infinite points on a circle
therefore there are infinite number of radii and hence there is no fixed number.
The answer is five remainder four
