The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is
Where a is the first term, n is the nth term, d is the common difference
On substituting there values,we will get
= 15(84000+52200) = 15*136200 =2043000
And for company A, it is
Difference between them =2043000-2002500= 40500
So the correct option is the second option .
Answer:r-1
Step-by-step explanation:
(-r-5)-(-2r-4) Or (-r-5)-(-2r-4)
-r+-5+2r+4. -r-5+2r+4
r-1 r-1
You bring down the first Parentheses Then have to multiply the (implied 1) -1•-2=2 and -1•-4=4 and do the math regularly
The graph below shows the velocity of two bicyclists A and B in arace from time t=0 to time t=16. The racers start side by side andtravel along the same road. The race begins at time t=0 and at timet=16 one of the racers completes the course.
Hey!!
How do you find slopes?
Ans - In order to find slop, we will need to use the slop formula which is
( y₂ - y₁ ) / ( x₂ - x₁ )
Now let's take two points on the graph
I will take the points ( -1 , 0 ) and ( 1 , 2 )
Now let's plug in these values :
y₂ = 2 , y₁ = 0 and x₂ = 1 and x₂ = -1
( 2 - 0 ) / ( 1 + 1 )
2 / 1
Hence, the slope is 2
Hope my answer helps!!
