Answer:
The parametric equations represents an ellipse by the rectangular equation 
.
Step-by-step explanation:
We proceed to use the following trigonometric identity to derive an expression in rectangular form:
(1)
Where:
and 
Then, we expand the expression as follows:
(2)
The parametric equations represents an ellipse by the rectangular equation .
Answer:
w = -7.04 and 1.705
Step-by-step explanation:
First lets distribute.
We have 8w-6w(w-4), so let's distribute the -6w to w and -4
8w-6w^2+24w = 2(w+9)
Now for the other side we distribute 2 to w and 9
8w-6w^2+24w = 2w +18
Now we combine like terms
6w^2+32w = 2w +18
Carry both 2w and 18 to the other side
6w^2 +30w -18 = 0
Now we can factor the equation, i used the quadratic method which is x= -b+- the square root of b^2-4ac /2a (in this case x would be w)
Plugging that in:
x= -32 +- square root of 32^2 -4(6 * -18) / 2(6)
-32 +- square root of 1024 +1728 / 12
-32 +- square root of 2752 /12
-32 +- 52.46 /12
x = -32 - 52.46/12 and -32 + 52.46/12
x= -84.46/12 and 20.46/12
x= -7.04 and 1.705
so w = -7.04 and 1.705
Sorry this was so complicated, but I hope this helps
A) One tenth is equal to 0.1, so you do 830,000 x 0.1 to get 83,000 people. You can also do 830,000 divided by 10 to get the same answer since it is one-tenth.
B) You can divide 5280 by 4 to find the answer of this one.
C) Divide by 4 again (because it is a fourth), but then multiply by three because the question asks for three-fourths.
D) A minute is 60 seconds, so 60 divided by 3 is 20. Given that it asks for two-thirds, you then multiple 20 by 2 to get the final answer of 40 seconds.
E) There are 24 hours in a day, so divide 24 by 8.
Hopefully this helps "get the ball rolling" for you!
