Answer:

3boxes

Step-by-step explanation:

1st we should know the number of cookies

7*5=35

Divide the total of cookies to cookies per box 35/12=2 11/12

2 boxes and 11 cookies remaning (they need an extra box)= 3 boxes

Solve the differential equation 3ydx+(xy+5x)dy=0

Brrunno [24]

The ODE is separable:

$3y\,\mathrm dx+(xy+5x)\,\mathrm dy=0\implies x(y+5)\,\mathrm dy=-3y\,\mathrm dx\implies\dfrac{y+5}y\mathrm dy=-\dfrac3x\,\mathrm dx$

Integrating both sides gives

$\displaystyle\int\left(1+\frac5y\right)\,\mathrm dy=-3\int\frac{\mathrm dx}x\implies y+5\ln|y|=-3\ln|x|+C$

Which of the following represents the zeros of the function

umka21 [38]

<span>g(x) = x^3 - 9x^2 + 2x + 48 ?

Probe some roots. When you use x = - 2

you will have: (-2)^3 - 9(-2)^2 + 2(-2) + 48 = -8 - 36 - 4 + 48 = 0

So, - 2 is a root

From that you can divide x^3 - 9x^2 + 2x + 48 by x + 2 and you will get

x^2 - 11x + 24

Then you can factor that: (x - 8)(x - 3)

So, the three roots are x = - 2, x = 3 and x = 8, which is the option B.

Answer: option B. x = 8, x = -2 , and x = 3

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,

alina1380 [7]

Answer:

We are have the function f(x).

Part 1: It is given that the function f(x) is transformed to f(x)+2.

This gives us that the function is translated 2 units upwards.

As, the y-intercept of f(x) is f(0). So, the y-intercept of f(x)+2 is f(0)+2, which is also translated 2 units up.

Translation does not change the behavior of the function.

So, if f(x) is increasing (or deceasing), then f(x)+2 will be increasing(or decreasing) respectively.

Moreover, f(x)+2 will be even or odd if f(x) is even or odd respectively.

Part 2: It is given that the function f(x) is transformed to $\frac{-1}{2}f(x)$

This gives us that the function is shrinked vertically by a factor of $\frac{1}{2}$ followed by a reflection across x-axis.

Also, the y-intercept of is $\frac{-1}{2}f(0)$ .

The graph of f(x) after changing to $\frac{-1}{2}f(x)$ will flip over the x-axis.

So, the function $\frac{-1}{2}f(x)$ will increase or decrease when f(x) decrease or increase respectively.

Moreover, $\frac{-1}{2}f(x)$ will be even if f(x) is even or odd respectively.
