Answer:
342.85714 %
Step-by-step explanation:
Percentage increase is given by
increase= (new - original)/ original * 100 %
The new is 186 and the original is 42
= (186 - 42)/ 42 * 100 %
=144/42* 100 %
=3.42857 * 100%
=342.85714 %
Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
5.2(2)*6=
5.2(2)*6=
I think it’s right
We can use synthetic division as a short cut solution to answer this problem. First is we put the root on the left side and the numerical coeff. in the right side. Then we bring down 1 and start multiplying to the root. Add the numbers in column.
-10 | 1 0 -75 250
-10 100 -250
1 -10 25 0
Since the final answer is 0, <span>x + 10 a factor of the function f (x) = x^3 - 75x + 250.</span>
