Answer:

Option (C)

Step-by-step explanation:

Cost of ordering the number of shirts is represented by the function,

f(x) = 12.75x + 3.5

where x = number of players in the bowling team

Since number of players a bowling team can have,

6 ≤ x ≤ 10

Therefore, domain of the function: 6 ≤ x ≤ 10

For x = 6,

f(6) = 12.75(6) + 3.5

= 80

For x = 7,

f(7) = 12.75(7) + 3.5

= 92.75

For x = 8,

f(8) = 12.75(8) + 3.5

= 105.5

For x = 9,

f(9) = 12.75(9) + 3.5

= 118.25

For x = 10,

f(10) = 12.75(10) + 3.5

= 127.5 + 3.5

= 131

Therefore, for the given domain range of the function will be,

Range : {80, 92.75, 105.5, 118.25, 131}

Option (C) will be the answer.

Assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt. x2 + y2 = 25 (a) Fin

Artemon [7]

Answer:

(a) $\frac{dy}{dt}=-3\frac{3}{4}$

(b) $\frac{dx}{dt}=3\frac{3}{4}$

Step-by-step explanation:

$x^{2} +y^{2}=25$

Take $\frac{d}{dt}$ of of each term.

$\frac{d}{dt}(x^{2})+\frac{d}{dt}(y^{2})=\frac{d}{dt}(25)\\\\(\frac{d}{dx}(x^{2})*\frac{dx}{dt}) +(\frac{d}{dy}(y^{2})*\frac{dy}{dt})=\frac{d}{dt}(25)\\\\2x\frac{dx}{dt} +2y\frac{dy}{dt} = 0\\\\$

For Question a

$2y\frac{dy}{dt}=-2x\frac{dx}{dt}\\\\\frac{dy}{dt}=\frac{-2x\frac{dx}{dt}}{2y} \\\\\frac{dy}{dt}=-\frac{x}{y}\frac{dx}{dt}$

Given that x = 3, y = 4, and dx/dt = 5.

$\frac{dy}{dt}=-\frac{3}{4}*5=-\frac{15}{4}\\ \\\frac{dy}{dt}=-3\frac{3}{4}$

For Question b

$2x\frac{dx}{dt}=-2y\frac{dy}{dt}\\\\\frac{dx}{dt}=\frac{-2y\frac{dy}{dt}}{2x} \\\\\frac{dx}{dt}=-\frac{y}{x}\frac{dy}{dt}$

Given that x = 4, y = 3, and dx/dt = -5.

$\frac{dx}{dt}=-\frac{3}{4}*-5=\frac{15}{4}\\ \\\frac{dx}{dt}=3\frac{3}{4}$

Use the Midpoint Formula three times to find the three points that divide the line segment joining (x1, y1) and (x2, y2) into fo

fredd [130]

We are given points $A(x_1,y_1)$ and $B(x_2,y_2)$ .

We first find the midpoint M, of AB, which divides the segment AB into 2 equal parts,

then we find the midpoint N of AM, and midpoint K of MB.

Thus each of the half parts is divided into 2 equal parts. The whole segment is divided into 4 equal parts.

The coordinates of M, N and K are found as follows:

the coordinates of M are: $( \frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

the coordinates of N are:

$\displaystyle{( \frac{x_1+\frac{x_1+x_2}{2}}{2} , \frac{y_1+\frac{y_1+y_2}{2}}{2})=( \frac{\frac{2x_1+x_1+x_2}{2}}{2} , \frac{\frac{2y_1+y_1+y_2}{2}}{2})$

$=\displaystyle{(\frac{3x_1+x_2}{4}, \frac{3y_1+y_2}{4})}$

similarly, the coordinates of k are:

$=\displaystyle{(\frac{x_1+3x_2}{4}, \frac{y_1+3y_2}{4})}$
