Answer:
−1.13348172≤x≤1.13348172
Step-by-step explanation:
For this problem
Add −5x2 to both sides of the inequality.
−x16 + 1 + 5x2≥0
Convert inequality to an equation.
−x16 + 1 + 5x2 = 0
Factor −x16 + 1 + 5x2
Set the factor equal to 00.
x16−5x2−1 = 0
x≈ − 1.13348172,1.13348172
so,
x≤ − 1,13348172
−1.13348172≤x≤1.13348172
x≥1.13348172
−1.13348172≤x≤1.13348172
Answer:
-88
Step-by-step explanation:
If a=2, we can say that - would be -4.
Secondly, if a=2 and b=-6 we can assume that 4ab would become -48.
Finally, if b=-6 we can say that - would become -36.
Adding all of those up gives you -88, your answer.
Answer:
7
Step-by-step explanation:
Amplitude is the positive multiple of sin(theta) which is 7 here.
The problem is simply asking us to convert the units from BTU to units of foot pound force. To do this, we use the conversion ratio 1 BTU/778.169 ft-lbf. We do as follows:
1500 BTU/hr ( 777.169 lbf-ft / 1 BTU ) = 1165753.5 lbf-ft/hr
Hope this answers the question.
