Answer:

The complex number is B, [tex]3\sqrt{\frac{7}{5}}+\sqrt{-\frac{9}{5}}[/tex]

Step-by-step explanation:

A complex number should be written in the form [tex]a+bi[/tex], where a and b are real numbers, and i is an imaginary number.

Recall that [tex]\sqrt{-1}=i[/tex]. Since letter B has the second term [tex]\sqrt{-\frac{9}{5}}[/tex], we can say

[tex]\sqrt{-\frac{9}{5}}=\sqrt{-1\cdot\frac{9}{5}}=i\sqrt{\frac{9}{5}}[/tex]

Therefore, the number can be written as

[tex]3\sqrt{\frac{7}{5}}+i\sqrt{\frac{9}{5}}[/tex].

Step-by-step explanation:

I don't know what the parent function is. you did not specify that.

I guess it is f(x) = x² ?

anyway, x² is the prime example of a parabola, which simply opens upward and has the vertex (its minimum) at 0, 0.

now, g(x) is first of all multiplying this by -1.

that turns the original curve upside-down.

therefore, g(x) opens downward, and it has a maximum.

because of the mentioned upside-down action, this is a reflection across the x-axis.

the multiplication by 1/4 actually decreases the functional values compared to the basic x² curve, so the curve is below the x² curve and that means it stretches the original curve.

Answer:

First linear equattion is equation with two variables and its formlla is y=mx+b . Where y and x are variables and m is the slope . And b is rhe y intercept means the value which get from the value of x is 0. and x intercept is the value when y is 0

The scale ratio of a model is the proportionate ratio of the model's linear dimensions to the equivalent characters. The actual mural will be 5 inches wide and 11 inches tall.

The scale ratio of a model is the proportionate ratio of one of the model's linear dimensions to the equivalent characters in the original.

As it is given that Arnold is using a scale in which 12 inches represents 1 foot to paint the mural. but since we know that 12 inches are equal to 1 foot.

Therefore, the actual mural will also be 5 inches wide and 11 inches tall.

where the two sides are given equal, one side is common in there and they have a right angle between the mentioned two sides.

So, it makes it more reasonable

Hope you understood ~ ask me if there's any doubt or more questions !

Answer:

75°

Step-by-step explanation:

Let x = unknown angle

Therefore, if a right triangle has one angle that measures 15°:

⇒ x + 15 + 90 = 180

⇒ x + 105 = 180

⇒ x = 180 - 105

⇒ x = 75°

Explanation:

So 552 digits are used to number the pages of a book consecutively from page one. How many pages are there in the book?

1 to 9 = 9 digits

10 to 99 = 2*90 = 180 digits

So, 1 to 99 uses 189 digits.

552 - 189 = 363

3 digits per page = 363/3 = 121 pages starting at page 100.

Page 100 to 220 is 121 pages

220 pages in total

I hope this is logic is right - you might want a second opinion, too.

The number of the pages in the book which has a number from 1 to 552 digits will be 220.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

To number a book from 1 up to its last page took 552 digits.

Then the number of pages in the book will be

1 to 9 there are 9 digits.

From 10 to 99, the number of digits will be

2 × 90 = 180

10 to 99 there are 180 digits.

From 1 to 99, there are 189 digits.

Then the remaining digits will be

552 – 189 = 363

Three digits per page will be

363/3 = 121

Page starting at hundred.

Then the total number of pages will be

120 + 100 = 220

Then, you also have to add in all the numbers less than 5, which are 1, 2, 3, 4. Now, 1, and 3, are already selected so you need to add 2 and 4. This leaves you with a group of numbers, 1, 2, 3, 4, 5, 7, 9. Those are 7 numbers, out of the possible 10, which means there's a 7/10 chance. (70%) chance.

Only option A, [tex]f(x)[/tex] is a polynomial function is the correct answer based on the table given.

A polynomial is mathematical equation consisting of independent variables such that, for each value of the independent variable, the function have a unique value.

As for uniques values of the variable [tex]x[/tex], the value of the function [tex]f(x)[/tex] is unique so, [tex]f(x)[/tex] is a polynomial function.

The function, [tex]g(x)[/tex] is not a function as it have equal values for two different values of the variable [tex]x[/tex].

Option E and F are incorrect as, we can see in the table that sometimes the value of [tex]f(x)[/tex] is more and sometime the value of the function, [tex]g(x)[/tex] is more.

Thus, only option A is the correct answer.

The least number of tickets each person needs to buy to meet that goal of volleyball team is 3 tickets.

The algebraic expression are used to represent the general problem in the mathematical way to solve them to find the value of unknown variable.

Let suppose the number of tickets sold are n. As the volleyball team is selling raffle tickets for $1.50 each and the total fund raised by selling the ticket is $250.

Thus, the number of tickets sold are,

[tex]n=\dfrac{250}{1.5}\\n\approx167[/tex]

Now everyone buys the same number of tickets and there are 75 people at the fundraiser. Thus, the number of tickets purchased by each fundraiser is,

[tex]x=\dfrac{167}{75}\\x=2.23[/tex]

The number of tickets should be more than 2.23 buy by each people to earn the profit at least or more than $250.

Hence, the least number of tickets each person needs to buy to meet that goal of volleyball team is 3 tickets.
