Answer:
Step-by-step explanation:
A function is given to us and we need to find the x Intercepts of the graph of the given function . The function is ,
For finding the x intercept , <u>equate the given function with 0, we have ;</u>
Equate each factor with 0 ,
Divide both sides by 2 ,
Again ,
Taking squareroot on both sides,
Add 5 to both sides,
Similarly ,
<u>Hence</u><u> the</u><u> </u><u>x </u><u>Intercepts</u><u> </u><u>are </u><u>-</u><u>4</u><u> </u><u>,</u><u> </u><u>0</u><u> </u><u>and </u><u>5</u><u> </u><u>.</u>

Answer:
The answer is B and E.
Step-by-step explanation:
Given:
Radius of a circle = 21 m
Area of a sector of the circle = 27.72 m²
To find:
The angle at the center of the circle.
Solution:
The area of a second is:
Where, r is the radius of the circle and is the central angle.
Putting in the above formula, we get
Therefore, the central angle of the sector is .
Answer:
The common difference = 42
Step-by-step explanation:
We are given the hourly rate that the truckers charge for moving things.
We are supposed to find the common difference of the sequence according to which the truckers charge money.
From graph, for 3 hours,the cost is 204 and for 6 hours it is 330.
Only the cost for first hour is different and for the remaining hours its the same.
Common difference =
= 42
Also for the first hour, the cost = x + 2 44 = 204
x = 116
The arithmetic sequence = 116 + 42n
