A fishing club on the Restigouche River in Canada kept detailed records on the numbers of fish caught by its members between 188

0 and 1930. Average catch tends to be cyclic each decade with the average minimum catch of 0.9 salmon per day occurring in years ending with O an average maximum catch of ʼ salmon per day occurring in years ending with 5.t (Note: This exercise corresponds to the subsection Characteristics of a Sine Function and requires use of the formulas for average value, amplitude, period, and horizontal shift to construct sine models rather than curve-fitting using technology.) (a) Calculate the period and horizontal shift of the salmon catch cycle. Use these values to calculate the parameters b and c for a model of the form rx) = a sin(bx + c) + d, where x = 0 corresponds to the year 1880. (Round your answers to three decimal places.)
(b) Calculate the amplitude and average value of the salmon catch cycle amplitude average value salmon per day salmon per day (c) Use the constants from parts (a) and (b) to construct a sine model for the average daily salmon catch. (Round all numerical values to three decimal places.)

For each trip, a taxi company charges a fixed fee of $2.00 plus $0.75 for each 1/2 mile or fraction of 1/2 miles. If, for every
nydimaria [60]

Answer:

E: 2.00 + 0.75 [ 2r]

Step-by-step explanation:

r represents the number of miles. For each 1/2 mile the taxi will charge and extra free of $0.75. Then, for each mile, the taxi will charge $0.75*2. For example:

For a trip of 1 mile the taxi will charge:

$2.00+$0.75*2

For a trip of 2 miles, the taxi will charge:

$2.00+0.75*4

For a trip of 10 miles, the taxi will charge:

$2.00+$0.75*20

Notice that the variable fee (the one that depends on the number of miles) is $0.75 times the double of miles. In each case the number of miles is multiplied by two. Then the correct answer is E: 2.00 + 0.75 [ 2r]

Tariq lives in Palm Beach, Florida, and purchased a house for $250,000. The amount of millage for property tax is 11.8. What is
IRISSAK [1]

Answer:

$29500

Step-by-step explanation:

We have been given that Tariq lives in Palm Beach, Florida, and purchased a house for $250,000. The amount of millage for property tax is 11.8%. We are asked to find the amount of property tax that Tariq paid.

To find the amount of property tax paid by Tariq, we need to calculate 11.8% of $250,000.

\text{Amount of property tax paid by Tariq}=\$250,000\times \frac{11.8}{100}

\text{Amount of property tax paid by Tariq}=\$2500\times 11.8

\text{Amount of property tax paid by Tariq}=\$29,500

Therefore, Tariq paid an amount of $29500 in tax.

Which of the following ordered pairs are y-intercepts? Check all that apply
Varvara68 [4.7K]

A y-intercept is the value at which x = 0.

(4,0) is not a y-intercept because x = 4.

(-1, 1) is not a y-intercept because x = -1.

(0,0) is a y-intercept because x = 0.

(0, -7) is a y-intercept because x = 0.

(-2, 2) is not a y-intercept because x = -2.

(0, -0.25 is a y-intercept because x = 0.
