Answer:

(a^2+ax-y) (a^2+ax+y^2)

Step-by-step explanation:

a^4+2xa³+a²x²-y^4

(a^2+ax)^2-y^4

(a^2+ax-y) (a^2+ax+y^2)

Answer:

  (a^2 +ax -y^2)·(a^2 +ax +y^2)

Step-by-step explanation:

This can be factored as the difference of squares.

  a^4 +2a^3x +a^2x^2 - y^4 = a^2(a+x)^2 - y^4

  = (a(a+x) -y^2)(a(a+x) +y^2)

  = (a^2 +ax -y^2)·(a^2 +ax +y^2)

Answer:

Step-by-step explanation:

1). Figure given on the top shows two lines with red marks (on segments UT and SR) are equal in measure.

Therefore, UT ≅ RS

2). In the second figure, Two angles have been marked with red arcs are equal in measure.

Therefore, ∠C ≅ ∠D

3). Angle marked with red square is a right triangle.

∠D = 90°

Answer:

  15.8°

Step-by-step explanation:

The relationship between angle trig functions and sides of a right triangle is summarized in the mnemonic SOH CAH TOA. Here, we're given the side opposite the angle (the height of the deck), and the side adjacent to the angle (the horizontal distance). So, the applicable relation is ...

  Tan = Opposite/Adjacent

  tan(angle) = 1450/5128

Then the angle is found using the inverse tangent function:

  angle = arctan(1450/5128) ≈ 15.8°

The angle of depression is about 15.8°.

Answer:

165

Step-by-step explanation:

its the answer trust me rank me brainiest

Answer:

B. 165

Step-by-step explanation:

Table: x = 11 and y = 770

Graph: x = 11 and y = 605

770 - 605 = 165

Answer:

He is likely to be accurate.

Step-by-step explanation:

An estimate is a value that is close to the true or actual value. Usually, a sample from a smaller group is projected into a larger population. To crosscheck the trueness of the estimate, we compare the small sample to the large sample thus;

If 40 employees =  8 applicants for vacation

1200 employees = ? applicants for vacation

Cross multiplying the above gives;

1200 * 8

40

= 9600/40

= 240 applicants for vacation.

The figure 240 is close to the owner's estimate of 250.

Answer:

[tex]10\:\mathrm{meters}[/tex]

Step-by-step explanation:

We can use trigonometry for a right triangle to solve this problem:

[tex]\tan 18^{\circ}=\frac{h}{30},\\h=30\cdot\tan 18^{\circ},\\h\approx \fbox{$10\:\mathrm{m}$}[/tex].

The height of the flagpole is 10 meters.

"It is the angle from the horizontal upward to an object."

For given question,

Consider the following figure.

The angle of elevation is 18°

⇒ ∠ACB = 18°

Also, BC = 30 meters

We need to find the height of the flagpole i.e., we need to find the distance AB.

Consider a tan(∠ACB )

[tex]\Rightarrow tan(18^{\circ})=\frac{AB}{BC}\\\\ \Rightarrow 0.3249 = \frac{AB}{30}\\\\ \Rightarrow AB=9.747 ~~meters\\\\\Rightarrow AB\approx 10~~meters[/tex]

Therefore, the height of the flagpole is 10 meters.

Answer:

135c^7

Step-by-step explanation:

[tex]135c^7[/tex] is the simplified equation of the given expression.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

To simplify [tex]5c(3c^2)^3[/tex], we need to apply the power rule of exponents, which states that [tex](a^m)^n = a^{(m*n)[/tex].

In this case, we have [tex](3c^2)^3[/tex], which means we need to multiply the exponent 3 by the exponent 2, giving us 6. So, we can rewrite the expression as:

[tex]5c(3c^2)^3 = 5c(3^3c^{(2*3)})[/tex]

Simplifying further, we get:

[tex]5c(3^3c^6) = 5c(27c^6)[/tex]

Finally, we can simplify by multiplying 5 and 27, and adding the exponents of c:

[tex]5c(27c^6) = 135c^{(1+6)} = 135c^7[/tex]

Therefore, [tex]5c(3c^2)^3[/tex] simplifies to [tex]135c^7[/tex].

Answer:

A.

Step-by-step explanation:

in order for a function to be a function, one input must only have one output.

We see that in option B, -1 has two outputs (10, 18)

In option c, we see that -4 has two outputs (2, -2)

In option D, we see that -3 has two outputs (5, 0)

This means A is the correct option because each input has only one output.

Answer:

Let's try C

Step-by-step explanation:

Step-by-step explanation:

You find the rate of change by taking the change in y over the change in x. If you look at A, you'll quickly realize there is no change in y as x increases. If you look at B the same is true, as x increases y stays the same.

Answer:

The math club has 22 students, and the art club has 34 students.

Step-by-step explanation:

Given that there are a total of 56 students between the art club and the math club, and that the art club has 12 more students than the math club, to determine how many students there are in each club, the following calculation must be performed:

X + X + 12 = 56

2X + 12 = 56

2X = 56 - 12

X = 44/2

X = 22

Thus, the math club has 22 students, and the art club has 34 students.
