You can split the figure into a top and bottom box.
Top box has the measurements of 3 by 18 by 20. When you multiply those together you get the volume of that box- 1080.
Bottom box has the measurements of 15 by 8 by 8. Multiplied together for the volume is 960.
Adding the top and bottom box together (1080+960) you get a total of 2040 yards cubed.
Answer:
6cm is the correct answer
Answer:
Attachment 1 : 5x + 6y = 5, Attachment 2 : 4cotθcscθ
Step-by-step explanation:
Remember that we have three key points in solving these types of problems,
• x = r cos(θ)
• y = r sin(θ)
• x² + y² = r²
a ) For this first problem we need not apply the third equation.
( Multiply either side by 5 cos(θ) + 6 sin(θ) )
r
( 5 cos(θ) + 6 sin(θ) ) = 5,
( Distribute r )
5r cos(θ) + 6r sin(θ) = 5
( Substitute )
5x + 6y = 5 - the correct solution is option c
b ) We know that y² = 4x ⇒
r²sin²(θ) = 4r cos(θ),
r = 4cos(θ) / sin²(θ) = 4 cot(θ) csc(θ) = 4cotθcscθ - again the correct solution is option c
13*13= 169
12*19= 228
19*62= 1,178
This was very easy.
The answer is
(x,y)=(3,-4)
