What should be done to x^2+ 15x in order to create a perfect square?

Answers

To create a perfect square, add 225/4 in the quadratic function x²+ 15x.

What is a quadratic equation ?

Any equation of the form Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

We have a quadratic function:

= x²+ 15x

To create a perfect square, add and subtract by 225/4

= x²+ 15x + 225/4 - 225/4

= x²+ 15x + 15²/2² - 225/4

= (x + 15/2)² - 225/4

Thus, to create a perfect square, add 225/4 in the quadratic function x²+ 15x.

A hot tub has capacity of 1458 liters 487 liters and 750 ml were put in how much more needs to be put in

Answers

Well the easiest way we can do it is convert liters in to milliliters and since there are 1000 milliliters in a liter multiply 1458 by 1000 and 487 by 1000 which will get you 1458000 milliliters of capacity and the 487 liters turns into 487000 mililiters we add this to the 750 milliliters  to get 487750 milliliters. Now it is all a matter of subtracting to find out how much more needs to be put in. 1458000-487750=970250  milliliters. So the amount needed to fill the hot tub is 970250 ml or if you want to convert it back to liters 970.250 l

-9/4 v + 4/5 = 7/8 v=? step by step need help asap please

Answers

-9/4v + 4/5 = 7/8; First, you subtract 4/5 from each side to have variable v on a side and numbers on the other: -9/4v = 7/8 - 4/5; -9/4v = 35/40 - 32/40; -9/4v = 3/40; Then you divide each side to get the variable v alone on a side, and one number on the other: V= (3/40) / (-9/4); Dividing to fractions is equal to multiplying the first one by the inverse of the second: V= (3/40) * (-4/9); V= -12/360; V= -1/30; You can re-check your answer (very important): (-9/4)*(-1/30)+4/5=7/8; The answer has been approved. Hope this helps! :)

949 round off to the nearest hundred

Answers

Good luck on your assignment and enjoy your day!

900 The digit in the 'hundreds' place is the 

9
The nearest hundred will, therefore, be either 900 or 1000

A number less than 950 will round down, while a number from 950 upwards will round to 1000

We need to look at the digit in the 'tens' place to know whether we will round up or down. The digit in the '10s' place is 4.

949 is less than 950 so you round down to 900

Identify intervals on which the function is increasing, decreasing, or constant. g(x) = 4 - (x - 6)^2 ??

Answers

Taking the derivative will give you the velocity at any time.

g(x)=4-(x-6)^2

g(x)=4-(x^2-12x+36)

g(x)=4-x^2+12x-36

g(x)=-x^2+12x-32

dg/dx=-2x+12

So g(x) will be increasing when dg/dx>0

-2x+12>0

-2x>-12
