<span>Let's solve your equation step-by-step.
-x^2 = -36
</span><span>Step 1: Divide both sides by -1.
</span><span>-x^2/-1 = -36/-1
x^2 = 36
</span><span>Step 2: Take square root.

Answer:
y - 5 = 
(x - 1)
Step-by-step explanation:
Note that 
= 
Differentiate using the power rule
(a
) = na
Given
y = x
= x. 
= 
, then
=
When x = 1
= . 1 =
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = and (a, b) = (1, 5), thus
y - 5 = (x - 1) ← equation of tangent
What is the median of the set 1,5,8,10,11,12,14,17,19,21,22,23?
Ilia_Sergeevich [38]
The median of this set is 13.
Explanation: we have 12 numbers, so we take the number between number 6 and 7 which are 12 and 14, between 12 and 14 we got 13, so that’s the median.

Answer:
x = 2
Step-by-step explanation:
The product of secant lengths to the near and far circle intercepts is the same for both secants:
3 · (3+5) = 4 · (4+x)
24 = 4(4 +x) . . . . simplify
6 = 4 +x . . . . . . . .divide by 4
2 = x . . . . . . . . . subtract 4
