Answer:
60°
Step-by-step explanation:
x + 160° + 140° = 360°
x + 300° = 360°
x = 360° - 300°
x = 60°
Answers:
M for 1 is: 114
M for 2 is: 34
Why?
First you need to find out what the angle is for the corner to the left of angle 1 to do so
180-135 which equals 45
then to find on you take 180 (the sun of all interior angles in a triangle equal 180) and subtract all the angles give...
180-21-45= 114 (which makes since because angle one is obtuse and so is it)
Now for angle to you need to find the corner that is next to angle 1 to do so you do...
180-114 (because angle equals 114) this equals 66
Then you do 180-66-80 to get angle 2 which equals 34
Hope this helps :D
Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858
The question is not well-expressed, but it looks like you want to evaluate
5 + (-3) - 65 + (-3) - 65 + (-3) - 6
Answer:
-140
Step-by-step explanation:
First of all, note the following
- Multiplying a negative number by another negative number gives a positive number.
- Multiplying a negative number by a positive number gives a negative number.
- Multiplying a positive number by a positive number gives a positive number.
- Brackets mean multiplication.
So
5 + (-3) - 65 + (-3) - 65 + (-3) - 6
= 5 - 3 - 65 - 3 - 65 - 3 - 6
= -140
The solution for this problem would be:
f'(x) = 1 - 1/x^2 = (x^2 - 1)/x^2
is positive where |x| > 1
hence (-inf, -1) and (1, inf) are the regions in which f' is positive and therefore f is increasing.
Therefore, the answer is (-infinity,-1] U [1,infinity).
