This is what the graph should look like when you're using 2/3x=y-1 as the equation.
-66 is the 27th term.
You have a function in terms of n. Recall that n is the nth term in the sequence.
Substitute n = 27 into the equation to find the 27th term.
a₂₇ = -10 + (27 + 1)(-2) = -10 + (28)(-2) = -10 - 56 = -66
Answer the answer is A
thank you have a good day
Step-by-step explanation:
Answer:
The answer is 2pi
Step-by-step explanation:
To find the area of a cirlce, use the equation ( pi * r^2 ) so for a semi circle, which is half, simply divide that by 2. Plug in 2 for radius and you get 4pi/2 which simplifies to 2pi.
First find the slope using (y1-y2)/(x1-x2)
(-2-4)/(5+16) = -6/21 or -2/7
Then plug in one of the points into y-y=m(x-x)
y + 2 = (-2/7)(x - 5)
Distribute the slope.
y + 2 = -2x/7 + 10/7
Subtract 2
y = -2x/7 - 4/7
So the answer is A.
