16<2(3x-1)<28 divide all terms by 2
8<3x-1<14 add 1 to all terms
9<3x<15 divide all terms by 3
3<x<5
x=(3,5) in interval notation
On a number line, it would be a line segment from 3 to 5 with open circles at 3 and 5.
On a coordinate system graph, it would be an infinitely high shaded plane between the vertical lines x=3 and x=5
Recall that
sin²(<em>x</em>) = (1 - cos(2<em>x</em>))/2
so that
sin²(7<em>π</em>/8) = (1 - cos(7<em>π</em>/4))/2
sin²(5<em>π</em>/8) = (1 - cos(5<em>π</em>/4))/2
Then
sin²(7<em>π</em>/8) + sin²(5<em>π</em>/8) = (1 - cos(7<em>π</em>/4) + 1 - cos(5<em>π</em>/4))/2
… = 1 - 1/2 (cos(7<em>π</em>/4) + cos(5<em>π</em>/4))
… = 1 - 1/2 (1/√2 - 1/√2)
… = 1
Answer:
x=3
Step-by-step explanation:
First we will distribute the 4 into the (x+7) and 9 into (x-1).
You should then got
4x+28=9x-9+22
Afterwards we combine like-terms
4x+28=9x+13
Then, we put all the alike values on the same side together.
4x+28=9x+13
-4x -4x
___________
28=5x+13
-13 -13
____________
15=5x
You then divide both sides by 5 to isolate x
15/5= 3
x=3

Girl I don't even think that's possible to answer.
6. 1256.6cm
8. 570.2 cm
(I think that’s right, I solved your questions by using the formula calculator for cylinders on google!)
