Answer:
100 units
Step-by-step explanation:
We want to find x when ...
C = 11030
x² +10x +30 = 11030 . . . . fill in for C
x² +10x = 11000 . . . . . . . . subtract 30
x² +10x +25 = 11025 . . . . add 25 to complete the square
(x +5)² = 105² . . . . . write as squares
x +5 = ±105 . . . . . . . take the square root
x = -5 ±105 = {-110, 100}
The number of units manufactured at a cost of $11,030 is 100.
Answer:
it is number 4 why because
Answer:
plug in -3 where any x is in the equation. I reccomend doing it in parenthesis just so things work out nicely
Step-by-step explanation:
![x^2-x^3\\(-3)^2-(-3)^3\\(-3*-3)-(-3*-3*-3)\\(9)-(-27)\\9+27\\36](https://tex.z-dn.net/?f=x%5E2-x%5E3%5C%5C%28-3%29%5E2-%28-3%29%5E3%5C%5C%28-3%2A-3%29-%28-3%2A-3%2A-3%29%5C%5C%289%29-%28-27%29%5C%5C9%2B27%5C%5C36)
Answer:
34 degrees
Step-by-step explanation:
Assuming that ADJ is a right angle, we can add 4x and 3x-8 and set equal to 90 degrees to simply to get get x.
7x-8=90
Add 8
7x = 98
x= 14
Now that we know x, we can plug in the value to find angle CDJ.
3x-8
3(14)-8
34 degrees
