Answer:
x = 361/32
Step-by-step explanation:
I'm assuming that "8 x/2" is a mixed number.
Answer:
$872
Step-by-step explanation:
Simple interest = Principle * Rate * Time / 100
= ( 800 * 6 * 18/12 ) / 100
= $ 72
The balance after 18 months = principle + interest
= 800 + 72
= $ 872
Answer:
(5,2)
Step-by-step explanation:
You have to look to the X axis and you'll see the smiley face 5 bars/lines across from the vertex or 0.
Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.
So all you need to do is put the numbers into (x,y) and you'll get (5,2)
Hope this helps!
Answer:
x = 9
Step-by-step explanation:
6x = 4x + 18
6x - 4x = 18
2x = 18
x = 9
The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different, for sine and cosine respectively.
The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.
Here is a procedure, first take a derivative
Then compute critical points of a derivative
.
Then evaluate at .
You will obtain global maxima and global minima respectively.
The answer is .
Hope this helps.
