The standard equation of an ellipse is:
(x/h)^2+(y/k)^2=1 where h and k are the radii of the x and y axis...so
(x/14)^2+(y/10)^2=1 or if you prefer
x^2/196+y^2/100=1
ANSWER
The value of theta in the second quadrant is,
EXPLANATION
The given trigonometric equation is
This implies that,
This implies that the principal solution is
and it is an angle in the first quadrant.
But the solution we are looking for is an angle in the second quadrant.
This is given by
Answer: 2 19/24 hours was spent in practising.
Step-by-step explanation:
During the first hour, they practiced for 5/8 of an hour. During the second hour, they practiced for 2/3 of an hour. This means that the total time for which they practiced in the first 2 hours would be
5/8 + 2/3 = 31/24 hours
During the last two hours, they first practiced for 3/5 of an hour, took a 1/2 hour break and then practiced the rest of the time. This means that the rest of the time for which they practiced is
2 - (3/5 + 1/2) = 2 - 11/10 = 9/10
Therefore, the time they spent practicing in total would be
31/24 + 3/5 + 9/10 = 67/24 =
2 19/24 hours
The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30
Answer:
Nine less than twice a number 2x-9
Seven divided by a number 7-x
Ninety-nine plus the difference of eleven and five 99+(11-5)
Four-fifths more than three times. Number 3x+4/5
