Answer:x is 15
Step-by-step explanation:
Check all options:
A. The notion
represents the line YX. As you can see the line YX is present in the diagram.
B. Start with point Z, go to the point X and then to the point Y. You path is along ∠ZXY sides, this means that you can see ∠ZXY on the picture.
C. The notion
represents the ray ZX. On the picture is given segment ZX, not ray, then this option is false.
D. To form the ∠XYZ you have to connect points Z and Y. Without this connection ∠XYZ cannot be seen. This option is false.
Answer: True options are A and B.
Let's see.
We have function
. We have to determine if the function is even or odd or neither.
We can find this out in many ways but the assignment specifically asks to prove this algebraically.
Function is even if
, so,
Which is true since negative raised to an even power is positive to that same number.
Similarly, function is odd if
, that is,
.
So we have prooved that function
is an even function not an odd function and therefore also not neither.
Hope this helps.
Hello!
To solve this you have to find the ratio between the two cylinders
Cylinder 1 height is 30
Cylinder 2 height is 20
this is a 30:20 ratio
This can be reduced to a 3:2 ratio
Now you look for one that are also equal to 3:2
3 * 7 = 21
2 * 7 = 14
The answers are 3:2 and 21:14
Hope this helps!
