Answer 2

The period of the given periodic function is 48 sec.

What is periodic function?

A periodic function is a function which returns same values at regular intervals. Let f be a periodic function then  

f( x +P ) = f(x) , for every x in the domain of f and P is some non zero constant

P is the regular interval or period after which a periodic function returns same values.

P=[tex]\frac{1}{f}[/tex]

where [tex]f[/tex] is the frequency of the periodic function

or [tex]f[/tex] = no of cycles per unit time

Given that a periodic function goes through 5 cycles in 4 min

therefore frequency for this periodic function , f  is given by

[tex]f=\frac{5}{4}[/tex] cycles per min

or

[tex]f=\frac{5}{4*60} \\f=\frac{5}{240} \\[/tex]

[tex]f=\frac{1}{48}[/tex]   cycles per sec

Thus,

Period of the given periodic function , P =[tex]\frac{1}{f}=1/\frac{1}{48}=48[/tex] sec

B) The information we got from equation of the function is used to determine domain and range.

Given,

The whole amount spent is $750.

As a result, our equation is

ca = 750

calculating c,

c = 750 / a

The function's domain and range are:

a ≤ 5

Each prize now needs to be under 50.

= 50 ≤ c

Using the formula, ac = 750

A's maximum value is 75.

we can say that domain is

5 ≤ a ≤ 50

Step-by-step explanation:

-0.5x-3.69=x-1.9-2.39

Step 1: Simplify both sides of the equation.

−0.5x−3.69=x−1.9−2.39

−0.5x+−3.69=x+−1.9+−2.39

−0.5x−3.69=(x)+(−1.9+−2.39)(Combine Like Terms)

−0.5x−3.69=x+−4.29

−0.5x−3.69=x−4.29

Step 2: Subtract x from both sides.

−0.5x−3.69−x=x−4.29−x

−1.5x−3.69=−4.29

Step 3: Add 3.69 to both sides.

−1.5x−3.69+3.69=−4.29+3.69

−1.5x=−0.6

Step 4: Divide both sides by -1.5.

−1.5x/−1.5 = −0.6/−1.5

x=0.4

The value of x will be 0.4.

Which of the following is the solution to | x | +9 ≤7?
A. No solution
B. All values are solutions
C. x≤-2
D. x≤-2 and x> -16

Answers

The solution for the inequality | x | + 9 ≤ 7 is (option d) x ≤ -2 and x > -16

You can solve an inequality by: adding the same amount to each side; taking the same amount away from each side; multiplying or dividing each side by the same positive amount. The inequality symbol needs to be turned around if either side is multiplied or divided by a negative number. Therefore, the answer is x > 1.

Given,

The expression:   | x | + 9 ≤ 7

If | x | ≤ a ⇒ -a ≤ x ≤ a

Then,

-7 ≤ | x | + 9 ≤ 7

⇒ -7 - 9 ≤ x ≤ 7 - 9

⇒ -16 ≤ x ≤ -2

That is x ≤ -2 and x > -16.

Answers

The fraction expression (17)/(2)g - (9)/(2)h is not the same as (9)/(2)h-(17)/(2)g.

How to subtract fractions?

We are given the fraction expression;

(17/2)g - (9/2)h

Now, the fraction (17/2) is greater than (9/2) and as such the result of the subtraction of the fractions will be positive.

Now, if we change the order of the subtraction to be;

(9/2)h - (17/2)g

This means that the result will now be negative since (9/2) is less than (17/2).

Thus, we can conclude that the expression (17)/(2)g - (9)/(2)h is not the same as (9)/(2)h-(17)/(2)g.

b) The slope represent the hourly pay for each job.

c) The intercepts represent the fixed salary for each job.

d) The pay will be the same on both jobs after 25 hours, of $425, as given by the intersection point on the graph.

e) For 40 hours, the payment on Job A is of $635 and on Job B of $680, hence, due to the higher payment, Tommy should accept Job B.

What is a linear function?

A linear function is modeled by the following rule:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.

For this problem, the two functions are given as follows:

A(h) = 75 + 14h. (slope of 14 as when x changes by 2 y changes by 28).B(h) = 17h. (slope of 17 as when x changes by 2 y changes by 34).

The functions are graphed at the end of the answer.

Hence:

a) The rate of change for Job A is of $14, while the rate of change for Job B is of $17, and these are the hourly pay for each job.

b) The slope represent the hourly pay for each job.

c) The intercepts represent the fixed salary for each job.

The pay will be equal when:

A(h) = B(h)

Hence:

75 + 14h = 17h

3h = 75

h = 25.

d) The pay will be the same on both jobs after 25 hours, of $425, as given by the intersection point on the graph.

For 40 hours, the payments are given as follows:

A(40) = 75 + 14 x 40 = $635.B(40) = 17 x 40 = $680.

Hence:

e) For 40 hours, the payment on Job A is of $635 and on Job B of $680, hence, due to the higher payment, Tommy should accept Job B.

Answers

She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

To make the recipe,

3/4 quart of lemonade and 3 cups of cranberry juice

The ratio of cranberry juice to a quart of lemonade

⇒ 3/(3/4) = 4

To make the same recipe with 1(2/5) quarts of lemonade the ratio of cranberry juice to a quart of lemonade must be maintained.

So,

4 = cranberry juice / 1(2/5)

(5/7) × cranberry juice = 4

Cranberry juice = 28/5 ⇒ 5 (3/5).

Problem (PLEASE HELP AND EXPLAIN)

Jamar wants to hire a plumber to fix his shower. The plumber informs him that 1 shower job requires 3 hours of work. The plumber charges $25 per hour, but he will only accept British Pounds as payment. Every British Pound is worth $1.62. How many British Pounds will Jamar need to pay the plumber for the shower job?
Which two units canceled?
Why is it important to cancel units when solving problems with multiple units? Use at least 2 complete sentences.

Answers

Answer:

[tex] \sf \fbox{46.296 British Pounds}[/tex]

Step-by-step explanation:

1 shower job requires 3 hours of work,

plumber will fix only 1 shower that means he will work for 3 hours,

Charges of 1 hour = 25$

Charges of 3 hour = 25× 3 = 75$

The currency that plumber accept is British pound (£),

1 British pound (£) = 1.62 dollar ($)

x British pound = 75 dollar

[tex] \frac{1}{x} = \frac{1.62}{75} [/tex]

taking reciprocal both the side,

[tex] \frac{x \cancel £}{1\cancel£} = \frac{75 \: \cancel\$ }{1.62 \:\cancel \$} [/tex]

[tex]x = 46.296[/tex]

Jamar need to pay 46.296 British Pounds to plumber for the shower job.

The two units that were cancelled was Dollar & Pound.

It is required to cancel units because, mathematical operation does not work for different units. For e.g. If I have given two measurement one is volume(cm³) & another is length(cm) so I cannot add them.

[tex] \sf Volume + Length = Not \: possible [/tex]

Same thing happens with division Operation of two different units, the magnitude gets cancelled but unit still remains there.

A football team has P points.
P= 3W + D
Wis the number of wins.
D is the number of draws.
a) A team has 5 wins and 3 draws.
How many points does the team have?
b) After 35 games a different team has 50 points.
14 games were draws.
How many games has this team lost?

Answers

Answer:

a)18 points

Step-by-step explanation:

a)

[tex]p = 3(w) + d[/tex]

therefore

[tex]p = 3(5 \: wins ) + 3 \: draws [/tex]

find the product of 5 and 3

[tex]p = 15 + 3[/tex]

[tex]p = 18[/tex]

B) how many games lost

[tex]3x + 14 = 50[/tex]

[tex]3x + 14 - 14 = 50 - 14[/tex]

[tex]3x = 36[/tex]

[tex] \frac{3x}{3} = \frac{36}{3} [/tex]

[tex]x = 12 \: games \: won| [/tex]total Games= Games won + games drawn + games lost

[tex]35 = 12 + 14 + x[/tex]

[tex]35 - 26 = 26 - 26 + x[/tex]

[tex] \times = 18 \: games \: lost[/tex]
