Y= 5/2 x + 5 because you rise 5 up starting from (2,0) and run over 2 and that gives you slope and y-intercept is 5 because it the one point that cross through the y-axis
Answer:
2rcosθ+3rsinθ=6
Step-by-step explanation:
x=rcosθ
y=rsinθ
2rcosθ+3rsinθ=6
6 - 34 + 96 - 384 +...
a 1 = 6 , a 2 = a 1 * ( - 4 ) , a 3 = a 2 * ( - 4 ), a 4 = a 3 * ( - 4)...
a 5 = - 384 * ( - 4 ) = 1,536
a 6 = 1536 * ( - 4 ) = - 6,144
a 7 = - 6,144 * ( - 4 ) = 24,576
This is a sum of a geometric sequence:
S 7 = 6 - 24 + 96 - 384 + 1,536 - 6,144 + 24,576 = 19,662
Another way to solve this:
S 7 = a 1 * ( r^n - 1) / ( r - 1 ) = 6 * (( - 4) ^7 - 1 )/ (- 4 - 1)=
= 6 * (-16,385) / (-5 ) = 19,662
We are given

where
y is the cost in dollars
x is distance in dollars
now, we can find derivative



so,

So,
the rate of change of the cost in dollars with respect to the number of miles is 1.5.........Answer
Answer:
c = 1, f = 5, and r = 1
Step-by-step explanation:
5(1)/(5) = 1/(1)
5/5 = 1/1
1 = 1
