Answer:

Step-by-step explanation:
Let the function of quantity in the lung of air be A(t)
So 
so, A(t) = Amax sin t + b
A(t) = 2.8t⇒ max
A(t) = 0.6t ⇒ min
max value of A(t) occur when sin(t) = 1
and min value of A(t) = 0
So b = 0.6
and A(max) = 2.2

at t = 2 sec volume of a is 0.6
So function reduce to

and t = 5 max value of volume is represent
so,

when t = 5

so the equation becomes

Step-by-step explanation:
I didn't need the other angles, but right of the bat you can tell it's two right triangles back to back.
<em>y </em> has to be 90° , as you have noticed they already gave you 70° on the right side of the shape meaning if you were to add 90 which is why plus 70 what would that give you? 160.
the total interior for a triangles angles has to be 180°. if you do the math 180 - 160 you get the leftover 20° for x.
I suck at explaining stuff, hope this helps
Well 32 divided by 8 would be 4 so... 32 x 4 would be 128 so 128 times. If it’s not correct I’m really sorry.
Answer:
1. The equation is given as
324 = 220 +135 + C
2. We have 166 As the correct answer but is not in the option
Step-by-step explanation:
We are been given the following values
No. of trophies = 3
Total Legos required for all trophies = 324
No. of Legos for largest trophy(A) = 220
No. of Legos for smallest trophy(B) = 135
No. of Legos required for final trophy(C) which is unknown
Total legos will addition of everything
Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)]
Substituting the values
324 = 220 +135 + C
Making C subject of formula
324 = 355 + C
324 - 355 = C
-31 = C
135 + 31 = 166
We have 166 As the answer
