Take a quadratic equation in standard form:
If there exists a sum of two numbers that equal b, whose addends produce a product that equals c. You can rewrite the quadratic as a product of two binomials.


For example take
When thought through throughly, -5 had addends, -2 and -3 that produce 6 when multiplied
Thus, we can rewrite the quadratic as.

Recall the scenario about Eric’s weekly wages in the lesson practice section. Eric's boss has been very impressed with his work.
Ira Lisetskai [31]

Answer:

f(x)= 12x   where x is the number of hours worked (only whole numbers)

Domain= {10,11,12,13,.............., 25}

Range = { $ 120, $ 132,  $ 144,$ 156 ,$ 168, $ 180, $ 192, $ 204, $ 216, $ 228,        $ 240, $ 252, $ 264, $ 276, $ 288, $ 300}

Step-by-step explanation:

Let x be the number of hours worked then the function will be

f(x)= 12 (x)       for {x=10,11,12,13,.............., 25}

x cannot taken any fractional value or decimal value.

The domain of the function is the input values

Domain= {10,11,12,13,.............., 25}

Now range of the function is the set of all possible output values

f(10)= 12 *10= $ 120

f(11)=  12 *11= $ 132

f(12)=  12 *12= $ 144

f(13)=  12 *13= $ 156

f(14)=  12 *14= $ 168

f(15)=  12 *15= $ 180

f(16)=  12 *16= $ 192

f(17)=  12 *17= $ 204

f(18)=  12 *18= $ 216

f(19)=  12 *19= $ 228        

f(20)=  12 *20= $ 240

f(21)=  12 *21= $ 252

f(22)=  12 *22= $ 264

f(23)=  12 *23= $ 276

f(24)=  12 *24= $ 288

f( 25) = 12*25= $ 300

Range = { $ 120, $ 132,  $ 144,$ 156 ,$ 168, $ 180, $ 192, $ 204, $ 216, $ 228,        $ 240, $ 252, $ 264, $ 276, $ 288, $ 300}

I need help on this please
irakobra [83]

Your answer would be the last option, 0.71.

To find the probability of the next pizza not being a cheese pizza, we need to find how many pizzas in the sample weren't cheese by adding them up. This gives us:

14 + 23 + 14 = 51

The total number of pizzas made is 21 + 14 + 23 + 14 = 72.

Therefore the probability of not making a cheese pizza would be 51/72 = 0.708 = 0.71

I hope this helps!

So if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7

A train leaves in Zurich at 22 40 and arrives in Vienna 07 32 the next day Work out the Time train takes
myrzilka [38]

Answer:

The train takes 8 hours and 52 minutes.

Step-by-step explanation:

Both Zurich and Vienna are in the same time zone, so there is no time to adjust the time zone.

Leaves: 22:40

Arrives: 7:32

From 23 to 7:32 there are (7 - 0) + (24 - 23) = 8 hours.

32 + (60 - 40) = 32 + 20 = 52 minutes.

The train takes 8 hours and 52 minutes.

At the beginning of a basketball season, the Panthers won 40 games out of 60 games. At this rate, how many games will they win i
Sholpan [36]
The panthers won 40 games out of 60, by hypothesis.
Let x be the number of matches they will win out of 110 games, if they keep the same rate. We'll use the rule of three:

40 games ---> 60 games
x games ---> 110 games

x = (110*40) / 60
x = 4400/60
x ≈ 73.33

So the panthers, at this rate, will win 73 games out of 110.

Hope this helps! :)
