Answer:

Linear

Step-by-step explanation:

$y=.35x+26$

$y=\frac{7}{20}x+26$ <em>.35 = 7/20</em>

The form $y=mx+b$ represents a linear equation. Our equation fits that form, with $m=\frac{7}{20}, b=26$ .

Evaluate the line integral, where c is the given curve. (x + 9y) dx + x2 dy, c c consists of line segments from (0, 0) to (9, 1)

viktelen [127]

$\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=\int_C\langle x+9y,x^2\rangle\cdot\underbrace{\langle\mathrm dx,\mathrm dy\rangle}_{\mathrm d\mathbf r}$

The first line segment can be parameterized by $\mathbf r_1(t)=\langle0,0\rangle(1-t)+\langle9,1\rangle t=\langle9t,t\rangle$ with $0\le t\le1$ . Denote this first segment by $C_1$ . Then

$\displaystyle\int_{C_1}\langle x+9y,x^2\rangle\cdot\mathbf dr_1=\int_{t=0}^{t=1}\langle9t+9t,81t^2\rangle\cdot\langle9,1\rangle\,\mathrm dt$
$=\displaystyle\int_0^1(162t+81t^2)\,\mathrm dt$
$=108$

The second line segment ( $C_2$ ) can be described by $\mathbf r_2(t)=\langle9,1\rangle(1-t)+\langle10,0\rangle t=\langle9+t,1-t\rangle$ , again with $0\le t\le1$ . Then

$\displaystyle\int_{C_2}\langle x+9y,x^2\rangle\cdot\mathrm d\mathbf r_2=\int_{t=0}^{t=1}\langle9+t+9-9t,(9+t)^2\rangle\cdot\langle1,-1\rangle\,\mathrm dt$
$=\displaystyle\int_0^1(18-8t-(9+t)^2)\,\mathrm dt$
$=-\dfrac{229}3$

Finally,

$\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=108-\dfrac{229}3=\dfrac{95}3$

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality

goldfiish [28.3K]

If a pharmacist is filling small empty bottles with cough syrup from a larger bottle. The statement that describes the number of small bottles the pharmacist can fill is: A. The pharmacist can fill 30 bottles or fewer.

<h3>Number of small bottles the pharmacist can fill</h3>

Given:

inequality=1,000-25x ≥250

Let x represent the number of small bottles

Hence:

1,000-25x ≥250

Collect like terms

1,000-250 ≥25x

750 ≥25x

Divide both side by 25x

x=750/25

x=≤30 bottles or fewer

Therefore If a pharmacist is filling small empty bottles with cough syrup from a larger bottle. The statement that describes the number of small bottles the pharmacist can fill is: A. The pharmacist can fill 30 bottles or fewer.
