B= the square root of 65
Formula: a^2= c*2-b^2
a^2= 81-16= 65
Once you find the square root of 65, thats your answer, but here they want you to keep it as 65.
Hope this helps!
Answer: f(2)=15, f(-2)=18, all real #s
Step-by-step explanation:
1. f(2)=4(2)^2-2+1=16-1=15
2. f(-2)=4(-2)^2-(-2)+1=16+3=18
A fleet of nine taxis is to be dispatched to three airports in such a way that three go to airport A, five go to airport B, and one goes to airport C. In how many distinct ways can this be accomplished?
2.44) Refer to Exercise 2.43. Assume that taxis are allocated to airports at random.
a) If exactly one of the taxis is in need of repair, what is the probability that it is dispatched to airport C?
b) If exactly three of the taxis are in need of repair, what is the probability that every airport receives one of the taxis requiring repairs?
So, my answer to 2.44a is 1/9. Hopefully this is correct at least :)
For 2.44b, my guess was
(3C1)(1/3)(2/3)2 * (5C1)(1/3)(2/3)4 * 1/3
The solutions manual on chegg (which seems to be riddled with errors) says something completely different. Is my calculation correct?
Answer:
b
Step-by-step explanation:
i think the answers b
Answer:
A.
Step-by-step explanation:
Given
Required
Determine the coordinates of C
Since, point D divides line AB in ratio, 5 : 3;
We start by calculating the coordinates of D;
This is done as follows;
Where
<em />
<em>Since AC is vertical</em>
<em>Then, Point C has the same x coordinate as A</em>
<em />
<em />
<em />
<em>Similarly;</em>
<em>Since CD is horizontal</em>
<em>Then, Point C has the same y coordinate as D</em>
<em />
<em />
<em />
Hence,
