Answer:
The shape of the graph of the parametric equations given is:
Step-by-step explanation:
By inserting each of the equations given in a graphing calculator (Annex 1), it can be identified that both the first and second equations have an elliptical or ellipse shape, which is characterized by being periodic in the two directions in which it runs. Thus, the equation x = 3 cos t runs with elliptical motion on the Y-axis of the Cartesian plane, while the equation y = 2 without t + 1 runs with elliptical motion on the X-axis.

Ok lets see if i can explain this properly. sorry it's long but i had to explain it properly
A) to calculate the final value received at the end of a period of time when the percentage is known we divide the percentage by 100 to give it to us as a decimal ( lets call this "X". this value is then added to 1 to give 1+X.
1+X is then put to the power of the period of time passed. in this case 3. so this gives us 1+X to the power of 3.
the initial value is then multiplied by 1+X to the power of three to give the value of the final answer.
so the equation used is final value = initial value * (1+X)^3
to give us the percentage we rearrange the equation to give us.
<u />x= (cube root of, final value/initial value) -1
= (cube root of, 42830/42000) -1
=0.0065 to two sig figs
as mentioned before to find X we divide the interest rate by 100. so to find the interest rate here we must multiply X by 100
=0.65%
B) 6%/ 100 = 0.06
0.06+1=1.06
1.06^4=1.263 to 3 decimal places
1.263*42000=53046
yes pablo will have 50000 at the end of the 4 years
This is not a random sample since she is outside of a pet store and the probability of people owning a dog coming out of that store is very very high. If she went around the neighborhood and knocked on people’s door and asked if they had a dog or not would be random sample.
