Answer:what equation?
Step-by-step explanation:
Answer:
I bellive its 4
Step-by-step explanation:
This is because 1,2,3 are for sure wrong. So if its not 4, its 5. But 95% sure its 4
The given curve is y = 5x -4, -1 ≤ x ≤ 3.
The length of the arc is computed from the formula
The derivative is
y' = 5
Therefore
Note that
x = -1 +> y = 5(-1) - 4 = -9
x = 3 => y = 5(3) - 4 = 11
The distance between the points (-1, -9) and (3, 11) from the distance formula is
D = √[(3-(-1))² + (11-(-9))²] = √(16+400) = 20.396
This answer agrees with that obtained by integration.
Answer: 20.396
Obtained by integration and verified by the distance formula.
Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
<u>+</u><u>7x-3y</u><u>=</u><u>-41</u>
<u>22x</u>=<u>-110</u>
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
<u>+25</u><u>.</u> <u>+25</u>
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
