The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
Well, this equation as a sum would be -46.38 + -24.6
so the answer would be -70.98.
I hope this helps, and have a fantastic day!
Answer:
option B
28
Step-by-step explanation:
Given in the question,
C(8,2)
Formula to use
<h3> nCr = n! / r! * (n - r)!</h3>
here n = 8
r = 2
We have to calculate combinations of 8 object taken 2 at a time, then
C(8,2)
8C2
8! / 2! * (8 - 2)!
56/2
28
So, 8C2 = 28
A) the Johnson family will travel 300 miles in 5 hours
Assuming 5, represents the amount of hours & 300 representing miles
Lliana has a 5/10, or 50% chance of getting chocolate milk
Vishal has a 2/10, or 20% chance of getting apple juice
