Answer:
yes; -1² is 1.
if you put -1 in parentheses, like this (-1)², then it comes out as 1
Answer:
y = -2x+4
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
= (-4-2)/(4-1)
= -6/3
= -2
point slope form
y-y1 = m(x-x1)
y-2 = -2(x-1)
distribute
y-2 =-2x +2
add 2 to each side
y-2 +2 =-2x+2+2
y = -2x+4
in slope intercept form
y = -2x+4
Answer:
5
Step-by-step explanation:
The height of the largest triangle = √(9 * 25) = 3 * 5 = 15
y is the square root of (25^2 + 15^2)
y = √(625 + 225)
y = √850
y = √(2 * 5*5 * 17)
y = 5 * √34
5 goes in the box.
I suppose the third term should say -10/3, not -103.
Notice that
-2 = -6/3
-4 = -12/3
so that, starting with the first term <em>a</em>(1) = -6/3, the every following term is obtained by subtracting 2/3.
-2 - 2/3 = -6/3 - 2/3 = -8/3
-8/3 - 2/3 = -10/3
-10/3 - 2/3 = -12/3 = -4
and so on.
So the recursive rule is
<em>a</em>(1) = -2,
<em>a</em>(<em>n</em> + 1) = <em>a</em>(<em>n</em>) - 2/3, for <em>n</em> ≥ 1
or C.
