Answer:
The equation is 
Step-by-step explanation:
From the equation we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally the polar equation for e = 1 and y = + c is mathematically represented as
So
Answer:
4 2/3 hours
Step-by-step explanation:
There are 7 days in a week
2/3 of an hour per day * 7 days
2/3 *7 = 14/3 hours
Changing to a mixed number
4 2/3 hours
Answer:
x = 7
Step-by-step explanation:
I reversed it for easy viewing:
(x+7)/3x = 2/3
<=> (x + 7).3 = 2.(3x)
<=> 3x + 21 = 6x
<=> 21 = 6x - 3x
<=> 3x = 21
<=> x = 7
<span>Find
the number of bluejays bird and robins birds as joan counted it
=> the number of Robins is twice as bluejay
=> Robins = 2X
=> The number of bluejay is about to know:
=> Bluejay = X
The total number of birds is 21.
=> 2X + X = 21
=> 3x = 21
=> 3x / 3 = 21 / 3
=> x = 7
Thus the number of bluejay is 7
=> Robin = 2(7)
=> Robin = 14
Thus the number of Robin is 14</span>
Let's use PEMDAS for this expression (parentheses, exponent, multiplication/division, addition/subtraction) Even though subtraction is first, you would multiply first because multiplication is before subtraction So multiply -(1/4) and (4/9) and you get -(1/9). Now add (2/3) and you get a final answer of (5/9)
