A company has found that the number of items sold, x, depends upon the price, p at which they're sold, according the equation x=77000−5p^2

The price has been increasing by $7 per month. Find the rate at which revenue is changing when the price is $70. Note: the answer might be negative

Answers

Answer 1

Since the price has been increasing by $7 per month, the rate at which revenue is changing when the price is $70 is $24500/month

To answer the question, we need to know what revenue is

What is revenue?

This is the total price for the total amount of goods sold.

Revenue, R = px where

p = price and x = quantity = 77000 - 5p²

So, R = px

= p(77000 - 5p²)

= 77000p - 5p³

The rate at which the revenue is increasing

To find the rate at which the revenue is increasing with respect to price, we differentiate R with respect to p.

So, dR/dp = d(77000p - 5p³)/dp

= 77000dp/dp - 5dp³/dp

= 77000 - 15p²

The rate at which the revenue is changing with the price is $70

Substituing p = 70 into dR/dp, we have

dR/dp = 77000 - 15p²

dR/dp = 77000 - 15(70)²

= 77000 - 15(4900)

= 77000 - 73500

= 3500

The rate at which the revenue is changing per month

The rate at which the revenue is changing per month is

dR/dt = dR/dp × dp/dt where dp/dt = rate at which price is changing = $7 per month.

Now, dR/dt = dR/dp × dp/dt

So, dR/dt = 3500 × $ 7/month

dR/dt = $24500/month

So, the rate at which revenue is changing when the price is $70 is $24500/month

f (x) =-3x+25; Find f(x)=52

Answers

Solution for -3x+25=52 equation:

Simplifying

-3x + 25 = 52

Reorder the terms:

25 + -3x = 52

Solving

25 + -3x = 52

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-25' to each side of the equation.

25 + -25 + -3x = 52 + -25

Combine like terms: 25 + -25 = 0

0 + -3x = 52 + -25

-3x = 52 + -25

Combine like terms: 52 + -25 = 27

-3x = 27

Divide each side by '-3'.

x = -9

Simplifying

x = -9

Do not write beyond this border.

Answers

Answer:

Step-by-step explanation:

a) ∫from 0 to 2 of te^(4-t^2) dt. Let u = 4-t^2. du= -2dt. And, tdt= -dy/2.

If x=0, u= 4 and if x=2, u=0.

Therefore our new integral will be, -(1/2) ∫ from 0 to 4 of e^u du.

= -(1/2)(e^u) | 0 to 4

= -(1/2)(e^0 - e^4)

= -(1/2) + (1/2)e^4

= (1/2)(e^4 -1)  miles

Therefore, from t=0 to t=2, Chloe has travelled a distance of (1/2)(e^4-1) miles.

b) At t=3, C(t)=12-3t-t^2

C(t) is already a function of velocity so simply plug in C(3), which is -6 miles/hour.

We also need to know acceleration.

C'(t)= -3 - 2t

C(3)= - 9 miles/hour squared.

Therefore, since velocity and acceleration are both negative, Chloes speed is increasing at t =3 hours.

At a tournament, the bowling league is providing 160 sandwiches for its members. The table shows the number of different types of sandwiches that were ordered. The ratio of turkey sandwiches to roast beef sandwiches is 5:3. Drag the numbers to complete the table.

Answers

Answer: See below

Step-by-step explanation:

The total number of ordered sandwiches is 160

The total number of Turkey Sandwiches is 80

The ratio of Turkey to Roast Beef is 5:3

So from this, 5 times of a value is 80

So 5x = 80

And x = 16

So the Roast beef sandwiches are 16×3=48

Therefore, the table is:

Sandwich type       Number

Turkey                         80

The angles in a quadrilateral are 4y - 10°, y + 40°, 3y + 20° and 2y + 10° in order as you go around the quadrilateral.
a) Set up and solve an equation, to find the value of y.
b) Hence work out the value of each angle.
c) What type of quadrilateral is this?

Answers

Answer:

see explanation

Step-by-step explanation:

the sum of the interior angles of a quadrilateral = 360°

sum the 4 angles and equate to 360

4y - 10 + y + 40 + 3y + 20 + 2y + 10 = 360 , that is

10y + 60 = 360 ( subtract 60 from both sides )

10y = 300 ( divide both sides by 10 )

y = 30

then 4 angles are

4y - 10 = 4(30) - 10 = 120 - 10 = 110°

y + 40 = 30 + 40 = 70°

3y + 20 = 3(30) + 20 = 90 + 20 = 110°

2y + 10 = 2(30) + 10 = 60 + 10 = 70°

Since the angles measures are in order around the quadrilateral, then

the opposite angles are congruent, thus quadrilateral is a parallelogram

A two-sided test of H0: μ=0, α=0.05 (two sided), yields a p-value of 0.19. Will the 95% confidence interval for μ include 0?

Group of answer choices

No

Unknown

Yes

Answers

Answer:  Yes

Explanation

Rule: if the p-value is smaller than alpha, then we reject the null.

We're given a p-value of 0.19 and alpha = 0.05

Based on that rule, it means we fail to reject the null (i.e. "accept" the null), since the p-value is not smaller than alpha.

Therefore, we conclude that mu = 0 must be the case, which means this value is in the confidence interval.

If mu = 0 was outside the confidence interval, then we would reject the null.

Based on the supply and demand of the baseball caps, the relevant supply quantities are:

a. 20,000 baseball caps. b. 60,000 baseball caps.c. 30,000 baseball caps. d. 40,000 baseball caps.

What quantity of baseball caps will be supplied domestically?

At the price of €2, the supply according to the graph is:

= 20,000 baseball caps.

What quantity will be imported?

The quantity imported is shown as:

= Demand at €2 - Domestic supply at €2

= 80 - 20

= 60,000 baseball caps

What quantity will be supplied domestically with the tariff?

A tariff of €1 would increase the price to €3.

At this price, the supply would be:
= 30,000 baseball caps.

What quantity will be imported with the tariff?

At the new price, the quantity imported is:

= Demand at €3 - Domestic supply at €3

= 70,000 - 30,000

= 40,000 baseball caps.
