Suppose a one year subscription to a magazine cost $12.99 and a three-year subscription cost $25.98 the cost and length of the subscription are related write an equation to a model the cost of a subscription for any period of time

Answers

Answer 1

Answer:

y = $38.97

y = 6.495(5) + 6.495

Step-by-step explanation:

So for this problem, since it states the cost and length of the subscription are related, you can use the two subscription costs as data (or coordinate) points.

1 year = 12.99, 3 year = 25.98; so (1,12.99), (3, 25.98) use these points to calculate the average rate of change (or the slope (m)).

(y - y1)/(x - x1) = m so, (25.98-12.99)/(3 - 1) = 6.495, this is the slope, m

y = 6.495(x) + b now just pick one of the points and put in the x and y values to solve for b

12.99 = 6.495(1) + b solve for b and you discover it also = 6.495 = b

so y = 6.495(x) + 6.495 is the equation of the line, to answer their question, just pop in x=5 for the 5 years subscription cost

y = 6.495(5) + 6.495

y = $38.97

An ice cream cone has a diameter of 3 inches and a height of 6 inches. How much ice cream can just the cone hold?

Answers

Answer:

14.13 cubic inch

Step-by-step explanation:

volume=(π x r^2 x h) divided by 3

Volume=(3.14x(1.5)^2x6) divided by 3

Volume=(3.14x1.5x1.5x6) divided by 3

Volume=42.39 divided divided by 3

The population of a certain inner-city area is estimated to be declining according to the model P(t)=259,000e−0.012t, where t is the number of years from the present. What does this model predict the population will be in 13 years? Round to the nearest person.

Answers

Answer:

259000 people

Step-by-step explanation:

Since t is the number of years, you sub 13 into the equation as t,

P(13)=259,000e−0.012(13)

= 258999.844 (round since its people --> 259000)

The biologist is expecting the number of salmon to rise during salmon season. If the ratio stays the same and he expects 120 Steelhead, how many Chinook should he expect to count at the dam? Show your work.

Answers

Based on the ratio of Chinooks to Steelhead, if there are 120 Steelheads, the biologist should expect to count 48 Chinooks.

How many Chinooks will the Biologist find?

The first part of the question shows that for every 4 Chinooks, there are 10 Steelheads.

The ratio of Chinooks to Salmon is therefore:
= 10 / 4

= 2.5

This means that for every 1 Chinook, there are 2.5 Steelhead.

If there are 120 Steelheads, the number of Chinooks would be:

= 120 / 2.5

= 48 Chinooks

in a company 37% of the 1500 employees are females

work out the number of males in the company

I'm struggling pls help me

Answers

Answer:

Answers : 945 males

Step-by-step explanation:

37%

555 females

1500 - 555

total males = 945

Answer:

945 males

Step-by-step explanation:

37% of 1500 = female

37% of 1500 = 555 (number of females)

1500 - 555 = number of males

1500-555 = 945

To double check this, we can do:

100% - 37% = 63% of 1500 are males

63% of 1500 = 945

So, the answer is 945

I can assure you this is the correct answer.

Hope this helps! If you need further explanation, let me know!

The time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds

Functions and values

Given the height of the ball expressed by the function below;

h = -16t^2 + 96t + 112

where

t is the time in seconds

If the car is 156ft above the ground, hence

Substitute

-16t^2 + 96t + 112 = 156

Multiply through  by -1
16t^2 - 96t -  112 = -156

16t^2 - 96t -  112 + 156 = 0
16t^2 - 96t + 44 = 0

4t^2 - 24t + 11 = 0
