Answer:

-4x^2+232x-675

Step-by-step explanation:

x*(232-4x-7)-3(232-4x-7) remove the term from the first parentheses and multiple. Then, remove the parentheses .

232x-4x^2-7x-696+12x+21 Calculate the like terms and then rearrange.

=-4x^2+232x-675.

Hope that helps.

Answer:

-4x^2 + 237x - 675

Step-by-step explanation:

(x - 3)*(232 - 4x -7) >> Distribute x and -3 to the trinomial

232x - 4x^2 - 7x - 696 + 12x + 21 >> Simplify

-4x^2 + 237x - 675

What is the slope of the line below

Fofino [41]

Answer:

C. $\frac{1}{2}$

Step-by-step explanation:

You can use the formula to find the slope: $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

(-1.5, 1.5) & (1.5, 0)

$\frac{0-(-1.5)}{1.5-(-1.5)} =\\\\\frac{0+1.5}{1.5+1.5} =\\\\\frac{1.5}{3} =\\\\\frac{1}{2}$

The slope is $\frac{1}{2}$

Mar 12: 3

erastovalidia [21]

Answer:

Mar 18: 125
Mar 19: 318
Mar 20: 743
Mar 25: 15,070

Step-by-step explanation:

The six seemingly arbitrary points have no common difference or ratio, so cannot be modeled by a linear or exponential function.

The differences of the differences are not constant at any level, so the only polynomial model is 5th-degree. It is ...

(6n^5 -95n^4 +600n^3 -1825n^2 +2814n -1320)/60

where n = days after Mar 11. (Mar 12 corresponds to n=1.) The domain is n ≥ 1.

____

The 5th-degree polynomial increases very fast, but not as fast as an exponential function would.

The values for Mar 12 through Mar 25 are ...

3, 8, 11, 16, 25, 50, 125, 318, 743, 1572, 3047, 5492, 9325, 15070

Analyze Corey’s work to find his error. What is Corey’s mistake? He substituted 80 for x instead of y. He should have added 88.2

Anni [7]

x is the temperature and y is the number of swimmers. If there are 80 swimmers, then y = 80 instead of x = 80

This is how Corey should have solved

y = 1.505*x - 88.21

80 = 1.505*x - 88.21 <--- replace y with 80

1.505*x - 88.21 = 80

1.505*x = 80 + 88.21 <--- add 88.21 to both sides

1.505*x = 168.21

x = 168.21/1.505 <--- divide both sides by 1.505

x = 111.767

x = 111.8

If there are 80 swimmers at the pool, then the possible outside temperature is roughly 111.8 degrees F. This temperature seems awfully large, so it's possible that Corey's regression equation has limited scope; in other words, it isn't too useful if x is outside a given interval
