Answer:
A=50.26548246units^2
Step-by-step explanation:
Radius is 4 because half the diameter (8) is the radius (4)
A=πr^2
A=π(4)^2
A=50.26548246units^2
Step-by-step explanation:
The largest possible ellipse will have a semi-minor axis of 2 feet and a semi-major axis of 4 feet. If we center the board on the origin of the cartesian coordinate plane, we can derive the location of the foci and thus, the length of string he will need:
x^2 / 16 + y^2 / 4 = 1
Vertices:
(-4 , 0) , (4 , 0)
(0 , -2) , (0 , 2)
Your choice of answer D is correct.
_____
When the number of days is zero, the height is 130 inches. This eliminates choices B and C. Evaluating the expression for n=13 gives
... 130 + 13×13 = 130 + 169 = 299 . . . . . corresponding to answer D.
Answer:
D
Step-by-step explanation:
This is exponential growth, and to my understanding, the format goes:
<em>initial amount (percent growth/ decay)^time</em>
percent growth = (<em>decimal percent + 1)</em>
<em>percent decay = (1 - decimal percent) </em>
Your equation:
1500(1.02)^t
Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.
i think
6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y
I hope this Helps!
