Answer:
smallest triangle BCD
x = 15
Step-by-step explanation:
9/x = x/(16 + 9)
x² = 25(9)
x = ±15
Answer:
probably way over 50% of the time I'm not 100% sure tho
20/100 = x/12
The 20/100 in the expression represents the 20%. The x in this scenario is the unknown amount in which the person will tip. The /12 is the cost of the original price. So, in order to find the value of x, you would need to cross multiply.
x = $2.40
The total cost would be $2.40 + $12.00 = $14.40
Oh maybe that since the derivative of sine is cosine and cosine is bounded above by 1, then
<span><span><span><span>sin(x)−sin(0) /</span><span>x−0</span></span>≤1</span>
\frac{\sin(x)-\sin(0)}{x-0}\leq 1</span> so
<span>sin(x)≤<span>x</span></span>
