You can look at -32 as being -2^5 so if you write (-2^5)^3/5 the 5's cancel out making it -2^3 which equals -8
Answer:
It is arithmetic and it has a common difference of -99
Answer:
the zero of a function is the value of x which makes the final value zero
First Equation:
So let 25 - 2x equal to 0
<em>25 - 2x = 0</em>
x = 12.5
Second Equation:
Let 2x² - 11x - 6 equal to zero
<em>2x² - 11x - 6 = 0 </em>
<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>
<em>2x(x - 6) + 1(x - 6) = 0</em>
<em>(2x + 1) (x - 6) = 0</em>
So we can transpose either one of the brackets below the zero
(2x + 1) = 0 or (x-6) = 0
x = -1/2 or x = 6
Answer:
Step-by-step explanation:
(-1,5)....x1 = -1 and y1 = 5
(-5,-5)..x2 = -5 and y2 = -5
slope = (y2 - y1) / (x2 - x1)
slope = (-5 - 5) / (-5 - (-1) = -10 / (-5 + 1) = -10/-4 = 5/2 <===
Answer:
= 4√53 units
that is option(a)
Step-by-step explanation:
all sides of the square are of the same length
so if we get the length if this side, we can calculate its perimeter
there's this formula,
<u>side length between two points, let's say A(x, y) and B(p, q), is equal to </u>
so here we go,
the same points A and B here are
(4, 7) and (-3, 5)
therefore, side length :-
the side length comes out to be <u>√(</u><u>53</u><u>) </u>
now perimeter of a square is
4 × side length
= 4√53 units
