You solve for the domain by setting the radicand less than or equal to 0 and solving for x. Dividing by a -x, we switch the sign so we have that the domain is less than or equal to 0, or all negative numbers. We know that it breaks every law in math to have a negative radicand with an even index, so if the domain is all negative values of x, taking a negative of a negative gives us a positive. The negative sign OUTSIDE the radical means you are flipping the graph upside down. So instead of having a range of y is greater than or equal to 0 as does the parent graph, you have flipped it upside down so it heads more negative in regards to the range. Therefore, the domain and the range both have the same sign, thee last choice from above.
Centripetal acceleration is given by:
g=v^2/r
where:
v=velocity
r=rate
But
V=200 m/s, g=9.8 m/s^2
plugging the values in the formula we obtain:
9.8=200^2/r
r=200^2/9.8
r=4081.63 m
Filling in the given information, you are asked to find "r" from
64π = 4πr²
Dividing by 4π gives
16 = r²
And taking the square root tells you
4 = r
The appropriate choice is ...

Answer. No , we can say that all parallelograms are similar , because if we consider a rectangle and a square side by side , they are not similar to each other , we can take rhombus and square as another example . There are many types of parallelograms , with have something uncommon among themselves
