Answer:
13188mm^2
Step-by-step explanation:
D=60mm
H=136mm
L=140mm
then v=1/3xd^2x h= 1/3x3.14x60^2x136
SA=tc pl/2
=3.14x60x140= 13188mm^2
hope this helps!
<u>Answer</u>:
Therefore has one solution.
<u>explanation</u>:
Given equations:
6x + y = -7
-24x -7y = 25
Make y the subject:
6x + y = -7
y = -7 - 6x ..............equation 1
-24x -7y = 25
-7y = 25 + 24x
y = (25 + 24x)/-7 ..........equation 2
Solve them simultaneously:
(25 + 24x)/-7 = -7 - 6x
25 + 24x = -7 (-7 - 6x)
25 + 24x = 49 + 42x
42x - 24x = 25- 42
18x = -24
x = 
Then y is:
y = -7 - 6x
y = -7 - 6(
)
y = 1
Has one separate value of x and y: (
, 1 ); so it has one solution.
I think its c. because m-7 is difference and + 15 is increasing
The result of
is 
<h3>Composite functions</h3>
Composite functions are functions that are gotten by combining multiple functions
<h3>The functions</h3>
The functions are given as:


To calculate f(x) * g(x), we have:
![f(x) \times g(x) = [x^2 + 8x + 15] \times [x + 5]](https://tex.z-dn.net/?f=f%28x%29%20%5Ctimes%20g%28x%29%20%3D%20%5Bx%5E2%20%2B%208x%20%2B%2015%5D%20%5Ctimes%20%5Bx%20%2B%205%5D)
Expand the above expression

Collect like terms

Evaluate the like terms

Hence, the result of
