express the result in standard form.
US

Answers

Answer 1

Answer:

[tex](f\circ g)(x)=x^2+9x+20[/tex]

Step-by-step explanation:

We have the two functions:

[tex]f(x)=x^2+5x+6\text{ and } g(x)=x+2[/tex]

And we want to find:

[tex](f\circ g)(x)[/tex]

This is equivalent to:

[tex](f\circ g)(x)=f(g(x))[/tex]

Therefore, we will have:

[tex]f(x+2)[/tex]

By substitution:

[tex]f(x+2)=(x+2)^2+5(x+2)+6[/tex]

Simplify. Square and distribute:

[tex]f(x+2)=(x^2+4x+4)+(5x+10)+6[/tex]

Rearrange:

[tex]f(x+2)=(x^2)+(4x+5x)+(4+10+6)[/tex]

Combine like terms:

[tex]f(x+2)=(f\circ g)(x)=x^2+9x+20[/tex]

What are two other ways to name Z

The given set ℤ can be written as {..., -3, -2, -1, 0, 1, 2, 3, ...}.

The given set ℤ can be written as { x | x is an integer, -∞ < x < ∞}.

Disclaimer:

I assume that in the question indicates the set of all integers.

Sets are the basis of mathematics. One can write sets in different ways and form smaller sets of elements from a larger set.

Any set can be written in two forms.

Roster formSet-builder notation

Roster form:

Roster form is one way to write sets. The roster form lists the elements of a set within braces, { }. Let's see a few examples for the roster form.

We write the set containing the elements 5, 6, 7, and 8 as {5, 6, 7, 8}We write the set of multiples of 5 as {5, 10, 15, 20, 25, 30,...}.

So, the given set ℤ can be written as {..., -3, -2, -1, 0, 1, 2, 3, ...}

Set-builder notation:

Set-builder notation is another way to write sets. Set-builder notation describes by enumerating its elements or stating the properties that its elements must satisfy. Let's see a few examples for the set-builder notation.

We write the set containing the elements 5, 6, 7, and 8 as { x | x is a natural number, 4 < x < 9}We can write the set of multiples of 5 as { x | x is a multiple of 5}. This is read as "the set of all real numbers x, such that x is a multiple of 5".

So, the given set ℤ can be written as { x | x is an integer, -∞ < x < ∞}. This is read as "the set of all real numbers x, such that x is an integer".

The expression as a number in scientific notation is 4.2 * 10^5

How to write the expression as a number in scientific notation?

The expression is given as:

quantity 7 times 10 cubed end quantity times quantity 5.4 times 10 to the fourth power end quantity all divided by quantity 9 times 10 squared

Rewrite properly as:

[7 * 10^3 * 5.4 * 10^4]/[9 * 10^2]

Evaluate the product of 7 and 5.4

So, we have:

[37.8* 10^3 * 10^4]/[9 * 10^2]

Evaluate the product of 10^3 and 10^4

So, we have:

[37.8* 10^7]/[9 * 10^2]

Evaluate the quotient of 37.8 and 9

So, we have:

[4.2 * 10^7]/[10^2]

Evaluate the quotient of 10^7 and 10^2

So, we have:

4.2 * 10^5

Hence, the expression as a number in scientific notation is 4.2 * 10^5

Jordan uses 1/4 of the 31/2 yards of fabric she has to make a top. How many yards did she use?

Answers

The fabric left is 2 1/4 yards which is calculated using subtraction.

Total fabric = 3 1/2 = 7 / 2 yards

Used fabric = 1 / 4 yards

Fabric left will be calculated using subtraction.

So, we get that:

Left fabric = 7 / 2 - 1 / 4

= 14 / 4 - 1 / 4

= 13 / 4

= 2 1/4 yards.

Therefore, we get that, the fabric left is 2 1/4 yards which is calculated using subtraction.

The morning announcements said that two out of every seven sixth-grade students in the school have an overdue library book. Jasmine said, “That would mean 24 of us have overdue books!” Grace argued, “No way. That is way too high.”

How can you determine who is right?

Answers

Answer:

We need to know how many students are in sixth grade and compare the real number with the 84 sixth graders that Jasmine claims to be.

Step-by-step explanation:

We would need to know how many students are in sixth grade to determine who is right. If two students out of seven have an overdue library book and grace claims that 24 of them are overdue by that means, what we would need to do is divide the allegedly 24 students between 2. Now we have 12 pairs of students that have overdue books. For every pair of students in sixth grade that have overdue books, seven students don’t have overdue books, so now we multiply 12 pairs of students with overdue books times 7 students who don’t have overdue books. By Jasmine calculation then, sixth grade have 84 students.  

If sixth grade have indeed 84 students, Jasmine is right. If there are not 84 students in sixth grade, she is wrong. Grace is right if there are fewer students than 84 in sixth grade.

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'y' to each side of the equation.

2x + -1y + y = -42 + y

Combine like terms: -1y + y = 0

2x + 0 = -42 + y

2x = -42 + y

x = -21 + 0.5y

Step-by-step explanation:

75x + -300 = 25x + 200

Reorder the terms:

-300 + 75x = 25x + 200

Reorder the terms:

-300 + 75x = 200 + 25x

Solving

-300 + 75x = 200 + 25x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-25x' to each side of the equation.

-300 + 75x + -25x = 200 + 25x + -25x

Combine like terms: 75x + -25x = 50x

-300 + 50x = 200 + 25x + -25x

Combine like terms: 25x + -25x = 0

-300 + 50x = 200 + 0

-300 + 50x = 200

Add '300' to each side of the equation.

-300 + 300 + 50x = 200 + 300

Combine like terms: -300 + 300 = 0

0 + 50x = 200 + 300

50x = 200 + 300

Combine like terms: 200 + 300 = 500

50x = 500

Divide each side by '50'.
