Line 1 to 2: Commutative Property of Multiplication, because all that changed was the order of the things being multiplied.
Line 2 to 3: Commutative Property of *Addition*, because all that changed was the order of the things being added.

All that changed in either step was the ordering of the things being multiplied or added. That’s the commutative property.

Answer:

The quality control facility operates for 10 hours each day.

Step-by-step explanation:

The given function models the number of cars that are put through a quality control test each hour at a car production factory.

The given function is

$c(t)= -t^2+8t+20$

We need to find the number of hours does the quality control facility operate each day.

Rewrite the given function it factored form.

$c(t)= -t^2+(10t-2t)+20$

$c(t)= (-t^2+10t)+(-2t+20)$

Taking out the common factors from each parenthesis.

$c(t)= -t(t-10)-2(t-10)$

$c(t)= (t-10)(-t-2)$

$c(t)=-(t-10)(t+2)$

The factored form of given function is c(t)=-(t-10)(t+2).

Equate the function equal to 0 to find the x-intercept.

$0=-(t-10)(t+2)$

$t-10=0\Rightarrow t=10$

$t+2=0\Rightarrow t=-2$

Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.

Therefore the quality control facility operates for 10 hours each day.

You have 4/6 of a cup of lemonade concentrate. If you mix 1/3 of a cup of the concentrate with a quart of water you make a small

Vadim26 [7]

Answer:

Numbers of pitchers of lemonade = 8

Step-by-step explanation:

Given as

Amount of lemonade concentration = $\frac{4}{6}$ of a cup

Now, $\frac{1}{3}$ of a cup of concentration mix with $\frac{1}{4}$ of water

So, $\frac{1}{3}$ - $\frac{1}{4}$ = $\frac{1}{12}$ of cup of lemonade,

∴ The number of small pitcher of lemonade = $(\frac{4}{6} /\frac{1}{12} )$

= 4 × 2 = 8 Answer
