The formula
in solving the integral of the infinity of 3 is ∫3<span>∞?</span>(1<span>)÷((</span>x−2<span><span>)<span><span>(3/</span><span>2)</span></span></span>)</span><span>dx</span>
Substitute the numbers given
then solve
limn→inf∫3n(1/((n−2)(3/2))dn
limn→inf[−2/(n−2−−−−−√)−(−2/3−2−−−−√)
=0+2=2
Solve for the integral of 2 when 2 is approximate to 0.
Transpose 2 from the other side to make it -2
∫∞3(x−2)−3/2dx=(x−2)−1/2−1/2+C
(x−2)−1/2=1x−2−−−−√
0−(3−2)−1/2−1/2=2

Answer:
(A)129 Pounds
Step-by-step explanation:
Let x be the number of 23% zink alloy
Therefore:
Since the total result is 516 pounds
The number of pounds of 42% zink alloy =516-x pounds
We then have the resulting equation:
0.23x+0.42(516-x)=0.3725*516
0.23x+216.72-0.42x=192.21
Colect like terms
0.23x-0.42x=192.21-216.72
-0.19x=-24.51
Divide both sides by 129
x=129 pounds
Therefore, the number of pounds of 23% zink alloy that must be mixed is 129 pounds.
Answer:
C.
Step-by-step explanation:
Jack's rate = 28/2 = 14 boxes/hour
Walter's rate = 36/3 = 12 boxes/hour
Combined rate = 14 + 12
= 26 boxes/hour
26 = 65/t
26t = 65
Answer:
The area of the triangular garden is 
Step-by-step explanation:
we know that
The equilateral triangle has three equal sides and three equal internal angles (the measure of each internal angle is 60 degrees)
The area of a triangle applying the law of sines is equal to
In this problem we have a equilateral triangle
therefore
substitute
