MArishka [77]

Answer:

y=3x+16

Step-by-step explanation:

slope=(4-10)/(-4+2)=-6/-2=3

or slope=(-14-4)/(-10+4)=-18/-6=3

eq. of line is y-10=3(x+2)

or y=3x+6+10

or y=3x+16

Suppose that the price p (in dollars) and the weekly sales x (in thousands of units) of a certain commodity satisfy the deman

HACTEHA [7]

Answer:

dx/dt = 12 (in thousands of units /week)

Step-by-step explanation:

We have from problem statement that:

8*p³ + x² = 104 (1)

Where p is price in $, and "x" is the weekly sales in thousands of units

All variables x and p change in relation to time then

Differentiating on both sides of the equation, we get:

24*p²*dp/dt + 2*x*dx/dt = 0 (1)

We need to find dx/dt and we know

p = 20

x = 200

And price is falling at the rate of 0,5 $/week

Then plugging these values in equation (1)

24*p²*dp/dt = - 2*x*dx/dt

24*(20)²(-0,5) = -400*dx/dt

-4800 = -400*dx/dt

dx/dt = 4800/400

dx/dt = 12 (in thousands of units /week)

[Right Triangles Only] Pythagorean Theorem:
$\displaystyle a^2 + b^2 = c^2$

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify given variables.

a = 30

b = 3

c = x

Step 2: Find x

Let's solve for the general equation that allows us to find the hypotenuse:

[Pythagorean Theorem] Square root both sides [Equality Property]:
$\displaystyle \begin{aligned}a^2 + b^2 = c^2 \rightarrow c = \sqrt{a^2 + b^2}\end{aligned}$

Now that we have the formula to solve for the hypotenuse, let's figure out what x is equal to:

[Equation] Substitute in variables:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2}\end{aligned}$
Evaluate:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2} \\& = \boxed{ \sqrt{909} } \\\end{aligned}$
