# How do you factor this trinomial 4a^2-4a+1

Step-by-step explanation:

To write the factored form, multiply a*c from the standard form . Here it is 4*1 = 4.

Then find factors of 4 that add to b=-4.

4: 1,2,4

-2+-2 = -4

Split the middle term into -2x+-2x and factor by grouping.

Mom wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 20% syrup?

Let x pound of the sugar to make 20% syrup.

As per the statement:

Mom wants to make 5 Ibs of the sugar syrup.

We have to find how much water and sugar does she need to make 20% syrup.

By definition of proportion; we have

Simplify:

Multiply both sides by 5 we get;

Remaining = 5 -1 = 4 pounds of water

Therefore, 1 pounds of sugar and 4 pounds of water does she need to make 20% syrup.

The gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV = nRT, where n is the number of moles of the gas and R = 0.0821 is the gas constant. Suppose that, at a certain instant, P = 8.0 atm and is increasing at a rate of 0.14 atm/min and V = 13 L and is decreasing at a rate of 0.16 L/min. Find the rate of change of T with respect to time at that instant if n = 10 mol. (Round your answer to four decimal places.)dT/dt = ___ K/min

Step-by-step explanation:

We have to calculate the time derivative of T=PV/nR with P and V variable and n and R constants. This is:

What we have to do is the derivative of a product:

Substituting, we have:

where all these values are given since the time derivatives of P and V are their variation rate, using minutes.

We then substitute everything, noticing that already everything is in the same system of units so they cancel out:

And then just calculate:
