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.
Answer:
Simplifying
X + -4 = 2x
Reorder the terms:
-4 + X = 2x
Solving
-4 + X = 2x
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X = 4 + 2x
Combine like terms: -4 + 4 = 0
0 + X = 4 + 2x
X = 4 + 2x
Simplifying
X = 4 + 2x

Answer:
$3.4
Step-by-step explanation:
Total amount spent by Mila equals $71.05
She bought 5 yards of fabric at $12.85 per yard. Hence, the total amount she spent on fabric is 12.85 × 5 = $64.25
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $71.05
Amount spent on thread = $71.05 - Amount spent on fabrics.
Amount spent on thread = $71.05 - $64.25 = $6.8
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $6.8, one spool would cost $6.8 ÷ 2 = $3.4
