Tom [10]

p = 12x is the function rule to calculate the total number of pens when you know the number of boxes

<em><u>Solution:</u></em>

Given that,

Pen are shipped to the office supply store in boxes of 12 each

To find: Write a function rule to calculate the total number of pens when you know the number of boxes

Let "p" be the total number of pens

Let "x" be the number of boxes

Number of pens in each box = 12

Then from given information,

Total number of pens = Number of boxes multiplied by number of pens in each box

$p = x \times 12\\\\p = 12x$

Thus the function rule is found

Find a solution x = x(t) of the equation x′ + 2x = t2 + 4t + 7 in the form of a quadratic function of t, that is, of the form x(

Temka [501]

The particular quadratic solution to the ODE is found as follows:

$x=at^2+bt+c$
$x'=2at+b$

$(2at+b)+2(at^2+bt+c)=t^2+4t+7$
$2at^2+(2a+2b)t+(b+2c)=t^2+4t+7$

$\begin{cases}2a=1\\2(a+b)=4\\b+2c=7\end{cases}\implies a=\dfrac12,b=\dfrac32,c=\dfrac{11}4$

Note that there's also the fundamental solution to account for, which is obtained from the characteristic equation for the ODE:

$x'+2x=0\implies r+2=0\implies r=-2$

so that $x_c=Ce^{-2t}$ is a characteristic solution to the ODE, and the general solution would be

$x=Ce^{-2t}+\dfrac{t^2}2+\dfrac{3t}2+\dfrac{11}4$

Given the Functions.

Furkat [3]

Answer:

The Answer is: A, B, and E.

Step-by-step explanation:

The given equations are:

f(x) = -2x + 8

g(x) = 6x - 10

Test each option:

a. g(-1) = 6(-1) - 10 = -6 - 10 = -16, True.

b. g(2) = 6(2) - 10 = 12 - 10 = 2, True

c. f(4) = -2(4) + 8 = -8 + 8 = 0, False

d g(6) = 6(6) - 10 = 36 - 10 = 26, False

e f(2) = -2(2) + 8 = -4 + 8 = 4, True

Hope this helps!! Have an Awesome day!!! :-)
