Answer:

x = 27°

Step-by-step explanation:

Hello!

Complementary angles add up to 90°.

Since angles A and B are complementary, we can sum up the equations to 90° and solve for x.

The value of x is 27°.

Step-by-step explanation:

Rewrite the middle term.

Rerrange terms.

[tex]x^4+2x^2y^2+y^4-x^2y^2[/tex]

Factor first three terms by perfect square rule.

Step-by-step explanation:

Step-by-step explanation:

Answer:

x= -3

Step-by-step explanation:

2x + y = -2 ---> y = -2 - 2x

instead: 5x-2y = -23 ---> 5x - 2(-2 -2x) = -23 ----> 5x+4+4x= -23 ---> 9x= -27

                   ---> x = -3

We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.

Remember the exponent property:

[tex]\frac{a^n}{a^m} = a^{n - m}[/tex]

Here we have the expression:

[tex]\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2}[/tex]

We can reorder this to get:

[tex]\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2} = \frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2}[/tex]

The right side can be simplified to:

[tex]\frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2} = 64.04*10{12 - 3 - 2} = 64.04*10^{7}[/tex]

Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:

[tex]6.404*10^8[/tex]

Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).

Problem 36

Answer:  [tex]\boldsymbol{n(A \cap C) = 1}[/tex]

Reason:

To be able to count the number of items inside set [tex]A \cap C[/tex], we first need to determine what this set looks like. In other words, we need to know the number(s) inside this set.

The upside down U symbol is the intersection symbol. It indicates we want to find what the sets A and C have in common. In this case, it's the value "4" and nothing else. This number is in both set A and set C at the same time. It might help to draw a venn diagram as you see below. I'm ignoring set B entirely since your teacher is not asking about the set in this problem.

We can then say [tex]A \cap C = \{4\}[/tex]

There's only one item inside this set, which is why [tex]n(A \cap C) = 1[/tex]

Step-by-step explanation:

Each term is   the product of the previous two terms minus the term that is two before

3*5  - 3 = 12

5 x12 - 5   = 55

12 x 55 - 12 = 648

55 * 648  - 55 = 35 585

or each term is   term that is two before x  (term before -1)

3 (5-1) = 12

5 x (12-1) = 55

12 * (55-1) = 648

55 * ( 648-1) = 35 585

The required next term in the sequence is 35,185.

Inductive reasoning is defined as, tempting judgments by moving from the details to the fact. It's usually determined with inferential reasoning, where you move from known information to precise conclusions.

When a function is shifted right, the transformation rule is:

(x, y) = (x - h, y)

This means that the transformation is (d) A horizontal shift 16 units to the right

Since the parent function is a base linear function.

The transformation can also be represented as:

(x, y) = (x, k - h)

From the graph, we have:

The average rate of change is then calculated as:

Rate = (58.77 - 47.45)/(2021 - 2011)

Evaluate

Rate = 1.132

2022 is 11 years from 2011.

So, the predicted annual attendance for 2022 is;

Attendance = 47.45 + 1.132 * 11

Attendance = 59.90

The years with unusual growth are 2020 and 2021.

This is so because they have the same attendance.

Step-by-step explanation:

If you think about it, if you were to shift the side DC to the left until it aligns with FE, you would get a straight line. This line would be parallel, and equal to AB, which can be determined by using the right angles, which are given. So AB = FE + DC, and the value of AB is given as well as the value of DC. So plugging in the known values you get 20 = FE + 6. Now subtract 6 from both sides and you get 14 = FE. So FE is 14 inches
