Answer:
Profit = 935
Step-by-step explanation:
Purchase price: 500×1.28=640
Selling price: 500×3.15=1575
Profit: selling price - purchase price = profit
1575 - 640 = 935
Profit = 935
Answer:
<h3>
x = 3 units</h3><h3>
</h3>
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = h
b = 8/2 = 4
c = 5
<u>plugin values into the formula:</u>
h² + 4² = 5²
h² = 5² - 4²
x = √9
x = 3
Answer:
x = 3.7
Step-by-step explanation:
By applying sine ratio for the given angle B,
sin(39°) = 
sin(39°) = 
0.6293 = 
AD = 4.41
By applying tangent ratio for the given angle C,
tan(50°) = 
1.19 = 
1.19 = 
x = 3.7

Step-by-step explanation:
We can prove the statement is false by proof of contradiction:
We know that cos0° = 1 and cos90° = 0.
Let A = 0° and B = 90°.
Left-Hand Side:
cos(A + B) = cos(0° + 90°) = cos90° = 0.
Right-Hand Side:
cos(A) + cos(B) = cos(0°) + cos(90°)
= 1 + 0 = 1.
Since LHS =/= RHS, by proof of contradiction,
the statement is false.
