Answer:

Step-by-step explanation:

Hello

A beekeeper’s hives are making Honey at a constant rate. The profit from honey can be represented by the equation

P(t)= -16t^2 + 2050t +150, where t is the time in days and P(t) is the profit the beekeeper receives. After how many days should she harvest her honey to maximize profit?

A: 4212100

B: 2050

C: 150

D: 64

P(64)= -16(64)^2 + 2050(64) +150 = -16 * 4096 + 131200 + 150 = 65814

P(150)= -16(150)^2 + 2050(150) +150 = -16 * 22500 + 307500 + 150 = -52350

P(64)= -16(2050)^2 + 2050(2050) +150 = -16 * 4202500 + 4202500 + 150 = -63 037 350

The only is positif, it’s 64 days

An aquarium 2 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquariu
loris [4]

Answer:

Workdone = 2450Joules

Step-by-step explanation:

Let the top of the aquarium be at height 0.

Let the bottom of the aquarium be at height 1

F = mg = 2p◇x × g

F= 2000◇x × 9.8

F = 19600◇x

Workdone = 19600xdx

Total workdone = Integral (limits 0.5 -0)19600×dx

Total work = [9800x^2]^0.5

Total work= 9800× 0.5^2 = 2450 Joules

Victoria has a 2 pound package of flour. She uses 2/5 of the flour to make pizza. She then uses 3/10 of the remaining flour to m
timama [110]
One pound= 16 ounces 

2 x 16 = 32 ounces = 2 pounds

2/5 can also be expressed in decimal form as .4

so 32 x .4 = 12.8

and then 3/10 also is .3 

so 32 x .3 = 9.6 

add the two 12.8 + 9.6 = 22.4

Rationalize the denominator of $\frac{2}{3\sqrt{5} + 2\sqrt{11}}$ and write your answer in the form $\displaystyle \frac{A\sqrt{
vlada-n [284]

Answer:

<h2>19</h2>

Step-by-step explanation:

Given the surdic expression \frac{2}{3\sqrt{5} + 2\sqrt{11}}\\, to rationalize the expression, we will have to multiply the numerator and denominator of the expression by the conjugate of the denominator as shown;

= \frac{2}{3\sqrt{5} + 2\sqrt{11}} * \frac{3\sqrt{5} - 2\sqrt{11}}{3\sqrt{5} - 2\sqrt{11}}\\\\= \frac{2(3\sqrt{5} - 2\sqrt{11})}{(3\sqrt{5} + 2\sqrt{11})(3\sqrt{5} - 2\sqrt{11})}\\\\= \frac{6\sqrt{5} - 4\sqrt{11}  }{9\sqrt{25}+6\sqrt{55}- 6\sqrt{55}-4\sqrt{121}  } \\\\=  \frac{6\sqrt{5} - 4\sqrt{11}  }{9(5)-4(11)  }\\\\=  \frac{6\sqrt{5} - 4\sqrt{11}  }{45-44  }\\\\= \frac{6\sqrt{5} - 4\sqrt{11}  }{1}

Comparing the result \frac{6\sqrt{5} - 4\sqrt{11}  }{1} with the expression \frac{A\sqrt{B} + C\sqrt{D}}{E}, it can be seen that A = 6, B = 5, C = -4, D = 11 and E = 1

A+B+C+D+E = 6+5+(-4)+11+1

A+B+C+D+E = 11-4+12

A+B+C+D+E = 19

Hence the value of A+B+C+D+E is 19
