Find the distance between the points (1, 4) and (-2, -1).

Answers

The distance between the two points is √34

Distance between two points

The formula for calculating the distance between two points is expressed as:

D = √(x2-x1)² + (y2-y1)²

Given the coordinate points (1, 4) and (-2, -1). Substitute into the formula to have:

D = √(-1-4)² + (-2-1)²

D = √(-5)² + (-3)²

D = √25 + 9

D = √34

Hence the distance between the two points is √34

Darlene purchases 20,000 worth of stock on her brokers advice and pays her broker a 1.5% broker fee darlene purchases 20,000 worth of stock on your brokers advice and pays her broker a 1.5% broker freeshe sells her stock when it increases to $28,600.02 years later and uses a discount broker who charges $21 per trade compute Darlenes net proceeds after the broker fees are taken out

Answers

Answer:

Darlene's net proceeds after the broker fees are taken out is $8,279.

Step-by-step explanation:

From the question, the following can be obtained:

Basic cost of purchase of the stock = $20,000

Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300

Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300

Selling price = $28,600

Broker fees related sales = 21

The net proceed can therefore be calculated as follows:

Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock = $28,600 - $21 - $20,300 = $8,279

Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.

Camillo estimates the weight of his dog. The veterinarian says that the dog weighs 84 pounds. The percent error in Camillo's estimates is less than 10%.Decide whether each of the following weight estimates could have been Camillo's estimate.
a. 80 pounds yes or no
b. 78 pounds yes or no
c. 94 pounds yes or no
d. 77 pounds yes or no
e. 92 pounds yes or no
f. 75 pounds yes or no

Answers

Answer:

A.Yes B.Yes C.No D.Yes E.No F.No

Step-by-step explanation:

10% of 84 is 8.4 and 84-8.4=76.6 and anything between 76.6-84 could have been the estimate.

Final answer:

Camillo's weight estimate could have been 80 pounds, 78 pounds, 77 pounds, or 92 pounds.

Explanation:

The percent error measures the discrepancy between an estimated value and an actual value. It is calculated using the formula: Percent Error = (|Measured Value - Actual Value| / Actual Value) * 100%. Since the given problem states that Camillo's estimate has a percent error less than 10%, we can calculate the percent error for each weight estimate and determine if it is less than 10%.

a. 80 pounds: Percent Error = (|80 - 84| / 84) * 100% = 4.76%, which is less than 10%. So, yes, this could have been Camillo's estimate.
b. 78 pounds: Percent Error = (|78 - 84| / 84) * 100% = 7.14%, which is less than 10%. So, yes, this could have been Camillo's estimate.
c. 94 pounds: Percent Error = (|94 - 84| / 84) * 100% = 11.9%, which is not less than 10%. So, no, this could not have been Camillo's estimate.
d. 77 pounds: Percent Error = (|77 - 84| / 84) * 100% = 8.33%, which is less than 10%. So, yes, this could have been Camillo's estimate.
e. 92 pounds: Percent Error = (|92 - 84| / 84) * 100% = 9.52%, which is less than 10%. So, yes, this could have been Camillo's estimate.
f. 75 pounds: Percent Error = (|75 - 84| / 84) * 100% = 10.71%, which is not less than 10%. So, no, this could not have been Camillo's estimate.
