Answer: The first diagram you selected is the correct visual representation.
Check out the diagram I posted below. The red vertical line is x = 0, aka the y axis. The blue parabola is 3x = y^2. The green horizontal line is y = 6. The region bounded by these curves is the gray shaded region.
Spinning that gray region around the y axis results in the first diagram in your answer choices. The disk in pink is a cross section to help find the volume (through the use of integral calculus).
Answer:The ordered pairs (a,b) of a function are (b,a) for the inverse function.
Step-by-step explanation:
Given :-
sam and Bethan shareare in the ratio 5:4 respectively.
Total no of money is = 54ÂŁ
Solution :-
Let Sams share is be x ie = 5
Let Bethans share be y ie = 4
Total no of share is = 9
Therefore the persons share is (particular persons share / total no of share) *
total value of money
Ans : -
Therefore sams share x is = (5/9)* 54 =30ÂŁ
Therefore Bethans share y is = (4/9) * 54 = 24ÂŁ
Answer:
11 units
Step-by-step explanation:
Let's do it this way:
Length = l
width = w
initial equation for area is l * w
We know that l = w+5
substitute.
w+5 * w = 36
solve.
6w = 36
w=6
The width is 6 units.
6+5 = 11
length = 11 units
2A. Answer is 42.7. C squared minus B squared equals A squared. C^2 - B^2 = A^2. 48^2 - 22^2 = 42.66^2.
