Graph the function h(x) =-3x-1

The period of the graph is π/2.

The length of one function wave is referred to as the period. One entire wave in this situation is 180 degrees, or radians. Without using a graph, you can get this simply dividing 2 by the frequency, which in this case is 2.

Given: 5 sin (4πx)+3

Period = 2π / 4

Using simple multiplication, the cost of 1 1/3 pounds of raspberries equals 12 pounds.

Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.

Given,

Cost of 3/5 pounds of raspberries = $9

Cost of 1 pound of raspberries = 9 × 5/3

Cost of 1 pound of raspberries = 15 pounds

Cost of 1 1/3 pounds of raspberries = 4/3 × 15

By median ,  test scores of 40 students are listed below.  So five number summary is 25, 58,72,81,98

What are median in math?

First we need to sort the data from Smallest to largest data value which is allready sorted

n = 40

Five number summary can be calculated as

Minimum = 25

Q1 can be calculated as

Lower Half of 40 values is 20, so median of 20 values will give us 25th percentile so Median = (20+1)/2 = 10.5th here 10th value is 57 and 11th value is 59 so Q1 = (57+59)/2 = 58

Median = (n+1)/2 = (40+1)/2 = 20.5th value and 20th and 21st value is 72 so median = (72+72)/2 = 72

Upper 20 values after median will provide us Q3 or 75th percentile which can be calculated as 20+(20+1)/2 = 30.5th value so 30th value is 81 and 31st value is also 81. So Q3 = (81+81)/2 = 81

Max = 98

So five number summary is 25, 58,72,81,98

And correct boxplot for this data is A. Boxplot A is correct which shows correct five number summary.

The number of numbers circled with only one color found using arithmetic progression formula are 809 numbers

An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms in the sequence is constant

The given parameters are;

The set of the numbers written on the paper = Numbers from 1 to 2022

Numbers circled with red circles by Caitlin = All even numbers between 1 and 2022

Numbers Nicole circles using yellow = Numbers that are multiples of 5

Required; The number of numbers that are circled with one colour only

Solution; The even numbers are numbers that are a multiple of 2

The number of even numbers between 1 and 2022 are found using arithmetic progression formula as follows;

[tex] a_{n} = a_{1} + (n - 1)\cdot d[/tex]

Where;

[tex]a_{1}[/tex] = The first term = 2 (First even number)

d = The common difference = 2

n = The number of terms

Given that 2022 is an even number, we have;

[tex] a_{n} = 2022 = 2 + (n - 1)\cdot 2[/tex]

Which gives;

[tex] \displaystyle {n = \frac{(2022 - 2)}{2} + 1 = 1011} [/tex]

We note that 10 is the lowest common multiple of 2 and 5, which gives;

Multiples of 10 have two colors, therefore, the numbers that have only one color is given by the difference between the number of even numbers and the number of multiples of 10 as follows;

The number of multiples of 10 are;

[tex] \displaystyle {n = \frac{(2020 - 10)}{10} + 1 = 202} [/tex]

Which gives;

The numbers having only one colour = 1011 - 202 = 809

The distance traveled, d = 2/5 miles = 0.4 miles.

The time taken to travel 0.4miles is given as, t = 1/4 hr = 0.25 hr.

Thus, the average speed, s = distance traveled divided by time taken.

i.e.

we can now go through the options and see the correct answers:

option A is correct because unit rate per hour is the same thing as average speed

option B is wrong because average speed is greater than 1mile/hr from our calculation above

option C is wrong because 13/5 gives us 2.6 miles/hr

option D is correct because the average speed is indeed greater than 1

option E is wrong because average speed is 1.6 miles/hr not 2 1/4 miles/hr

Time taken by Victor to repay the subsidized student loan of $24,000 at an annual interest rate of 4.55% is equal to 59 months.

As given in the question,

Principal = $24000 (given)

Rate of interest = 4.55% (given)

Time duration of subsidized loan  = 8 years (given)

Repayment (equated monthly instalment) rate = $500 per month

To find: time for Victor to repay loan

We know that Principal + Simple Interest = Amount

Let t be the expected time duration for repayment of the subsidized student loan for Victor

24000+[tex]\frac{(24000).(4.55).t}{100}[/tex] = 500x12t  (Simple Interest = Principal x Rate x Time)/100

=> 24000 + 1092t = 6000t

=> 4908t = 24000

=> t = 4.89 years ≈ 59 months

Therefore,  it will take 59 months for Victor to repay the subsidized student loan of $24,000 at an annual interest rate of 4.55%.

The required monthly payment is $ 180,000

Simple interest is the cost of borrowing money that does not take compounding into consideration. In other words, just the principal is affected by simple interest. Simple interest is calculated by multiplying the principal by the time, interest rate, and time period. "Simple Interest = Principal x Interest Rate x Time" is the written formula.

Given: Principal= $60000

Rate= 8% and time= 25 years

To calculate the monthly payment use the formula:

Simple interest=PRT/100

= 60,000×8×25/100

=120,000

  2x^2 -4x +5 +8/(4x -1)

Step-by-step explanation:

You want to divide 8x^3-18x^2+24x+3 by 4x-1 using polynomial long division.

Polynomial long division is similar to numerical long division, except that the quotient term is always the ratio of the leading dividend term to the leading divisor term.

As with numerical long division, the dividend at each step is reduced by the product of the quotient term and the divisor.

When the dividend is of lower degree than the divisor, the division is finished. That dividend is the remainder.

The attachment shows the division in detail. Your result is ...

  q(x) +r(x)/b(x) = (2x^2-4x+5) +(8)/(4x-1)

The following statement is true about the triangles (d) D = 77 and E = 79

Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor,

Where the scale factor does not equal to one.

From the attached image, we understand that there are two shapes

The shapes are triangles

One triangle is the scaled factor of the other

So, the triangles are similar shapes

As a general rule, the following are the properties of a scaled copy of another figure

Using the above as a guide, we have the following

D =B = 77 -- by corresponding angles

Also, we have

E = A = 180 - 77 - 24 -- by corresponding angles

E = A = 79

Hence, the true statement is (d) D = 77 and E = 79

The definition is option B No, it is not differentiable at x = 0.

Given,

The function, f(x) = 8x²

We have to find that the function is differentiable at x = 0.

So, lets check:

f(x) = 8x²

x = 0

f'(0) = [tex]\lim_{h\to \ 0}[/tex] [tex]\frac{f(0+h)-f(0)}{h}[/tex]

f(0 + h) = 8(0 + h)² = 8 (0 + 0 + h²) = 8h²

f(0) = 8 × 0² = 0

f(0 + h) - f(0) = 8h² - 0 = 8h²

f'(0) = [tex]\lim_{h \to \ 0}[/tex] 8h²/h = 8h = 8 × 0 = 0

The estimation of numbers is the approximation of the said number.

This means that the estimation of a number is close to the said number, but it has a slight different value

The number of books is given as

Number of books = 253,625

From the question, we understand that:

You want to make sure that the number of books is enough

This means that we estimate the number of books to a number greater than 253,625

Jane sent= 31 messages

Ravi sent= x-8= 31-8 = 23 messages

Alan sent= 4(x-8) = 92 messages

The best way to solve an expression is from left to right if all the operations are the same (for instance, only addition, only subtraction, only multiplication, or only division). However, we must adhere to the order of operations for expressions including several operations.

The rule that dictates how to solve an expression involving numerous operations is known as the order of operations.

PEMDAS can help you remember that sequence. In PEMDAS, each letter denotes a mathematical operation.

Let, Jane sent x number of messages

Then, Ravi sent x-8 number of messages

and, Alan sent 4(x-8) number of messages

Total number of messages by them = 146

now,

x+(x-8)+4(x-8)=146

6x-40=146

x=31
