Demand for your tie-dyed T-shirts is given by the formula q = 510 − 90p0.5 where q is the number of T-shirts you can sell each m

telo118 [61]

Answer:

The demand will drop approximately 23 T-shirt per month.

Step-by-step explanation:

Consider the provided formula.

$q = 510-90p^{0.5}$

You currently sell T-shirts for $15 each and you raise your price by $2 per month,

That means p=$15 and $\frac{dp}{dt}=2$

We need to find how fast demand will drop.

So differentiate the above function with respect to time.

$\frac{dq}{dt} =0-45p^{0.5-1}\frac{dp}{dt}$

$\frac{dq}{dt} =-45p^{-0.5}\frac{dp}{dt}$

Substitute the respective values as shown:

$\frac{dq}{dt} =-45(15)^{-0.5}(2)$

$\frac{dq}{dt} \approx-23.24$

Hence, the demand will drop approximately 23 T-shirt per month.

Answer:

Question 22

x intercept is 7

y intercept is 4

The answer is C

Question 24

x intercept is -4

y intercept is 7

The answer is B

Step-by-step explanation:

x and y intercepts are the points at which the graph meets x and y axes.

x and y intercepts can be found the following way,

y intercept - substitute 0 to x

x intercept - substitute 0 to y

Question 22

$7y=28-4x$

Substitute x=0 to find the y intercept

$7y=28-4*0$

= $7y=28$

= $y=4$

Substitute y=0 to find x intercept

$7*0=28-4x$

= $0=28-4x$

= $4x=28$

= $x=7$

Therefore,

x intercept is 7

y intercept is 4

The answer is C

Question 24

$4y=7x+28$

Substitute x=0 to find the y intercept

$4y=7*0+28$

= $4y=28$

= $y=7$

Substitute y=0 to find x intercept

$4*0=7x+28$

= $0=7x+28$

= $-7x=28$

= $x=-4$

Therefore,

x intercept is -4

y intercept is 7

The answer is B
