Let the function f(x) have the form f(x) = Acos(x + C). To produce a graph that matches the one shown below, what must the value of A be?

Answers

A general cosine function has the form:

f(x) = A*cos(c + x)

We want to find the value of A that matches the one in the image, and we will find that A = 3

Ok, a general cosine function is:

f(x) = A*cos(c + x)

Where A is the amplitude.

To find the amplitude of a cosine function, we just need to find half of the difference between the maximum and minimum value of the function:

By looking at the given graph, we can see that the maximum is y = 3, and the minimum is y = -3

Then the amplitude is:

A = (3 - (-3))/2 = 6/2 = 3

The correct option is B.

Iceberg lettuce is grown and shipped to stores for about 30 cents a head, and consumers purchase it for about 72 cents a head. Find the percent increase.

Answers

The percent increase in sales of Iceberg lettuce is 140% .

What is profit percentage ?

Profit percentage are used to refer to the amount of profit that has been incurred in terms of percentage. It should also be stated that the profit percentage is one of the methods for comparing two quantities which the shopkeeper gets a profit.

How to calculate percent increase of the given product ?

It is given that Iceberg lettuce is grown and shipped to stores for about 30 cents a head and consumers purchase it for about 72 cents a head.

Thus cost price of the product is 30 cents whereas the selling price is 72 cents.

Therefore, profit incurred is = (72 - 30) = 42 cents.

Percent increase -

= (profit / cost price) * 100 %

= (42/30) * 100 %

= 140 %

Thus, the percent increase in sales of Iceberg lettuce is 140% .

#SPJ2

In this question, you divide the number it has increased, by original amount and times it by 100 to get the percent.

In this case, 72-30 = 42
42/30 = 7/5
7/5 x 100 = 140%

Four brothers each bought two hot dogs and a bag of chips at the football concession stand. If the bag of chips was $1.25, and the total was $18.20, which equation can be used to find the price of one hot dog?

Answers

Items bought in total:
4 brothers X two hot dogs and one bag of chips=
4X3=
12.

Hot dogs- x, chips- y.
4y + 8x= $18.20

Chips= $1.25 each so
4($1.25) + 8x= $18.20
5 + 8x= $18.20
8x= $18.20-5
8x= $13.20
x= $13.20/8 [13.20 divided by 8]
x= $1.65

This means that one hot dog= $1.65.
