Answer:

10.4403 or the square root of 109

Step-by-step explanation:

We do this by finding the height (3) and squaring it then the base (10) and squaring that, this sets up the Pythagorean theorem which is A^2+B^2=C^2 then you square C to find it's value

F(x)=-2x^2+4x+5<br> Find the critical numbers
frez [133]

Answer:

To find critical points, take the first derivative and set it equal to zero:

f(x) = -2x^2 + 4x + 5

f'(x) = -4x + 4

-4x+4 = 0

-4x = -4

x = 1

Critical point at x = 1

Alternatively, if you mean zeros, or where the x intersects, you can use the quadratic equation.

A tap can fill a bucket in 6 hours. After half the bucket is filled, three more similar taps are opened. What is the total time
777dan777 [17]

The total time taken to fill the bucket completely is 3 hours 45 minutes

The time taken to fill the bucket by one tap= 6 hours

Then the time take by one tap to fill half of the bucket= 3 hours

Part filled by one tap in one hour =\frac{1}{6}

Part filled by four taps in one hour =4(\frac{1}{6})=\frac{4}{6}=\frac{2}{3}

Given, that after half the bucket is filled, three more similar taps are opened

Then the remaining part = 1-\frac{1}{2}=\frac{1}{2}

Time taken to fill the half of the bucket= (\frac{1}{2} )(\frac{2}{3})=\frac{3}{4} hours

Convert the hours to minutes

(\frac{3}{4})60=45 minutes

Therefore,

Total time taken to fill the bucket= The time taken by one tap to fill half of the bucket+  Time taken by 4 taps to fill the half of the bucket

=3 hours+ 45 minutes

=3 hours 45 minutes

Hence, The total time taken to fill the bucket completely is 3 hours 45 minutes
