Answer:
cred că 34 îmi pare rău că nu am un român bun ;w;
Step-by-step explanation:
Step-by-step explanation:
Below is an attachment containing the solution.
I think you mean to find b in terms of the constants a, c and d.
(x + a ) / b - c = d
(x + a) / b = c + d
Cross multily:-
x + a = b(c + d)
b = (x + a) / (c + d)
Answer:
64π/5 cubic units.
Step-by-step explanation:
The line x = 2 and y = x^3 intersect at the point (2 , 2^3) = (2, 8).
The required volume = volume of the cylinder with height 8 and radius 2 - the volume of shape form between the curve and the y axis when revolved about the y-axis.
Using the disk method for volumes of revolution:
Note that x = y^1/3 so:
the second volume = Integral π ((y^1/3)^2) dy between y = 0 and y = 8.
= 3/5 y^5/3 * π between 0 and 8
= 96π/5.
The required volume = π 2^2 *8 - 96π/5
= 32π - 96π/5
= 64π/5.
Answer:
m<BAC= 110 degrees
Step-by-step explanation:
Since the outside angle m<BCD is 130 degrees the inside angle m<BCA would be 50 degrees. At this point you should know that inside angles of a triangle add up to 180 degrees so add the two angles that you know then subtract from 180 degrees. 50+20= 70 degrees and 180-70= 110 degrees.
