The answer above is mostly correct, HOWEVER The ellipse is a vertical ellipse and therefore uses the equation (x^2/b^2)+(y^2/a^2)=1
a=10/2=5
b=8/2=4
put it in the equation and it is (x^2/4^2)+(y^2/5^2)=1
Simplify and the answer is (x^2/16)+(y^2/25)=1
Answer:
The formula y = mx + b sometimes appears with
different symbols.
For example, instead of x, we could use the
letter C. Instead of y, we could use the letter F.
Then the equation becomes
F = mC + b.
All temperature scales are related by linear
equations. For example, the temperature in
degrees Fahrenheit is a linear function of degrees Celsius.

Answer:
long time huh You a fan of bts
Working out
Percentage= Difference/Original value x 100
Difference =4735-4049=686
P=686/4735
=0.1448... × 100
=14.5
Answer:
a) 2.5×2.5×2.5-1.4×1.4×1.4=12.881
b) (2.5)2+2.5×1.4+(1.4)2=31.5
Step-by-step explanation:
yuh multiple 2.5 three times and subtract 1.4 multiple three times. 2.5×2.5×2.5-1.4×1.4×1.4
15.625-2.744=12.881.
b) when opening bracket Yuh multiple the number in the bracket by the number outside the bracket. when bracket is open Yuh can now add, multiple to obtain your answer please
(2.5)2+2.5×1.4+(1.4)2
5+2.5×1.4+2.8
7.5×4.2=31.5
