Answer: Saturated solutions contain the maximum dissolvable amount of solute while unsaturated solutions contains less than that amount. Finally, a supersaturated solution can be formed by adding additional
solute to a saturated solution and then heating the solution. The solution can then be cooled and left undisturbed. If the solution is disturbed in some way such as a scratch on the glass or the addition of a “seed crystal”, the extra solute will come out of the solution as crystals.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =

andrey2020 [161]

we have

$f(x)=x^{2}-2x-3$

Find the roots

Equate the function to zero

$x^{2}-2x-3=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2}-2x=3$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$x^{2}-2x+1=3+1$

$x^{2}-2x+1=4$

Rewrite as perfect squares

$(x-1)^{2}=4$

Square root both sides

$(x-1)=(+/-)2$

$x=1(+/-)2$

$x=1+2=3$

$x=1-2=-1$

therefore

the answer is

$x=3$

Solve 5x-97>-34 or 2x+31<29

Komok [63]

I'll do both.

$5x-97>-34\Rightarrow x>\frac{-34+97}{5}=\frac{63}{5}=\boxed{12.6} \\\boxed{x\in(12.6, \infty)} \\ \\2x+31$

Answer:

The amount of money you will receive is $927.419

Step-by-step explanation:

Consider the provided information.

A youth group has a yard sale to raise money for a charity. The group earns $800 but decides to put its money in the bank for a while.

We need to calculate the amount of money if hot bank pays an interest rate of 3% compounded annually, and the youth group leaves the money in for 5 years.

Future value can be calculated as:

$FV=PV(1+r)^n$

Substitute PV=800, r=0.03 and n=5 in above equation.

$800(1+0.03)^5$

$800(1.03)^5=927.419$

Hence, the amount of money you will receive is $927.419
