Answer:
a = A/πb
Step-by-step explanation:
To solve this subject of the formulae given that A = πab.
<u>solution</u>
A = πab
the next step is to look for a unique way to get rid of the variables disturbing "a" from standing alone. this variables are π and b, we need to detach dem from a
A = πab
divide both sides by πb
A/πb = πab/πb
A/πb = a
a = A/πb
therefore the value of a in the fomular A = πab is evaluated to be a = A/πb
The answer is C
the mean is the average which is solved by adding up all of the numbers and then dividing that by how many numbers there are, 45/5 = 9
You would have to do length times the width or count all the sides.
Answer:
3 is the quotient and 5 is the remainder
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
For the ellipse
+ 
= 1
Then the vertices are (a, 0), (- a, 0) and (0, b), (0, - b)
Given
+ 
= 1
Then
a² = 4 ⇒ a = 2 and b² = 100 ⇒ b = 10
Hence the vertices are
(2, 0), (- 2, 0) and (0, 10), (0, - 10)
