Answer:

undefined.  

Step-by-step explanation:

so there is a point at the origin, and from there there are two rays coming off it.  One goes along the positive x axis, so it goes straight right, then the other goes through point (0,1).  That point is right above the origin.  So it makes an l shape.  what sort of polygon could you fit into the corner of an L?  Well, a square or rectangle, and the corners of a square and rectangle are all 90 degrees is theta.

Now it wants tan of 90 degrees.  tangent is sine divided by cosine, so let's find those.

sine of 90 is the y value on the unit circle at 90 degrees.  Since the unit circle has a radius of 1 then when it points straight up or down the y value is either 1 or -1 respectively.  Similarly cosine is 1 when pointing to the right, at 0 degrees or 360 degrees, and -1 at 180 degrees.  For sine straight up is of course 90 degrees and down is 270 degrees.

Now, sine of 90 is 1 and cosine of 90 is therefore 0.  so now we want sine divided by cosine.  this is 1/0.  Well you can't divide by 0, so it is undefined.

Step-by-step explanation:

Under a reflection in the line y = - x

a point (x, y ) → (- y, - x ), thus

S(- 2, - 10 ) → (10, 2 )

T(- 2, - 3 ) → T'(3, 2 )

U(3, - 3 ) → U'(3, - 3 )

V(3, - 10 ) → V'(10, - 3 )

Answer:

Horizontal shift to the right

Vertical compression

Reflection across the x axis

Vertical shift up

Step-by-step explanation:

Given that the parent function was [tex]g(x)=x^2[/tex]

we notice the following transformations:

a) a horizontal shift to the right in 1 (one) unit rendering: [tex]g(x)=(x-1)^2[/tex]

b) a vertical compression by multiplying our function by a number smaller than 1 ( [tex]\frac{1}{5}[/tex] ), rendering: [tex]g(x)=\frac{1}{5} (x-1)^2[/tex]

c) a reflection across the x-axis by flipping the sign of the function and rendering: [tex]g(x)=-\frac{1}{5} (x-1)^2[/tex]

d) a vertical shift of 7 units up thus giving finally: [tex]g(x)=-\frac{1}{5} (x-1)^2+7[/tex]

The parent function f(x) = x² has undergone a reflection across the x-axis, a vertical compression, a horizontal shift right, and a vertical shift up to transform into g(x) = -1/5(x - 1)² + 7.

The student asked about the transformations that turned the parent function f(x) = x² into g(x) = -1/5(x - 1)² + 7. Examining the function g(x), we can identify several transformations:

Considering these observations, the correct transformations from the provided options are f, e, h, and a.

Answer: 1 1/2 yards of yarn

Step-by-step explanation: For this problem, we will simply be multiply 1/2 yard by 3 to get the amount of yard that Ahlam will need.

1/2 x 3/1 = 3/2 or 1 1/2 yards of yarn. Basically you multiply the top of the fractions first (1 x 3) = 3 Then, you multiply the bottom of the fractions second  (2 x 1) = 2    (3/2 or 1 1/2)

Answer:

1.5 yards

Step-by-step explanation:

Salma: ½ yard

Ahlam: 3 × ½ = 1.5

Answer: C. 10 cm

Step-by-step explanation:

the hypotenuse of a right triangle will always be longer than the other 2 sides.  So 10 cm

To solve this you must use Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 8 cm

b = 6 cm

c = x

^^^Plug these numbers into the theorem

[tex]8^{2} +6^{2} =x^{2}[/tex]

simplify

64 + 36 = [tex]x^{2}[/tex]

100 = [tex]x^{2}[/tex]

To remove the square from x take the square root of both sides to get you...

√100 = x  

Which is when simplified:

(choice C)

10 cm

Answer:

C. k = -3

Step-by-step explanation:

First of all please try and understand math, cheating will never get you anywhere :)

So we can deduce that the value k is -3 for the following reasons:

If k is greater than 1, it will become narrower

If k is negative, it will shift right

Therefore we can conclude that k = -3

(I might be wrong but we will see)

The function g(x) transformed to f(x) by 3 unit on right side.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have the graph

g(x) = f(k x)

Here k represent the transformation or we can say shifting.

If  k is greater than 1 then the graph will become narrower

and, if  k is negative or less than then it will shift right.

From the graph the function g(x) is shifted to f(x) by 3 units.

Thus, the value of k is -3 ( Right side shifting)

(4x3 + 7z– 9x – 3) - (-523 + 11x – 4)

4x3 + 7z– 9x – 3 - (-523 + 11x – 4)     Distribute the negative over the parentheses:

=  4x3 + 7z– 9x – 3 + 523 - 11x + 4

= 4x3 + 7z– 9x - 11x– 3 + 523 - 4

Step-by-step explanation:

Answer: The radius of the circle is 7.75 m (approximately)

Step-by-step explanation: The area of a sector is determined as follows;

Area of sector = (∅/360) x πr²

The area has been given as 10π, and the angle subtended by the sector has been given as 60. Substituting for known values we now have;

10π = (60/360) x πr²

10π = (1/6) x πr²

By cross multiplication we now have;

(10π/π) x 6 = r²

10 x 6 = r²

60 = r²

Add the square root sign to both sides of the equation

√60 = √r²

7.7459 = r

The radius of the circle is approximately 7.75 meters

Answer:

D. square root of 2

Step-by-step explanation:

The square root of 2 is an irrational number because it cannot be written as a ratio of two integers.

Final answer:

Choice D, square root 2, is an example of an irrational number. Unlike the other options, it cannot be expressed as a fraction with an integer numerator and denominator.

Explanation:

An irrational number is a number that cannot be expressed as a simple fraction, meaning its decimal form is non-terminating and non-repeating. Among the options given, choice D, which is square root 2 (written as √2), is an example of an irrational number. Option A is 74/99, a fraction that simplifies to a rational number; option C is 3/4, also a rational number; and the option B is missing from the context provided.

To determine between which two consecutive integers an irrational number like √2 lies, we first identify the perfect squares nearest to the number we are taking the square root of. For √2, the perfect squares are 1 (√1) and 4 (√4), which correspond to the integers 1 and 2. √2 lies between these two integers because 2 is greater than 1 and less than 4, and since the square root function is increasing, √2 is more than 1 and less than 2.

Use the base and height to calculate the area of the triangular base, B.

The volume of the tent is 96 ft3.

A triangular prism is a polyhedron made up of two triangular bases and three rectangular sides. It is a three-dimensional shape that has three side faces and two base faces, connected to each other through the edges. If the sides are rectangular, then it is called the right triangular prism else it is said to be an oblique triangular prism.

Answer:

Open circle

Step-by-step explanation:

If the inequality has < or > it is an open circle.

If the inequality has =< or >= it is closed

Have A Great day

Answer:

Open circle. You only use a closed circle if it is greater/less than or equal to (which is the greater/less than sign with a line under it to indicate the "or equal to" part)

Step-by-step explanation:

The first thing is to define each one:

Polynomial: expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication. Exponents can only be natural numbers and the polynomial cannot have an infinite number of terms.

Example:

This is a:  [tex]5x^{3} + 4x^{2} -99x +20[/tex]

Degree: It is the exponent with the highest degree. If a monomial of those that are forming the polynomial has two unknowns, each with its exponent, these add up since we would be doing a multiplication of monomials.

Example: [tex]5x^{3} + 4x^{2} -99x +20[/tex]

The degree of this polynomial is 3 because it is the largest exponent.

Linear term coefficient: is the number that multiplies the variable with the highest exponent

Example: [tex]5x^{3} + 4x^{2} -99x +20[/tex]

In this case it is 5 because [tex]x^{3}[/tex] is the variable with the highest exponent

Constant term coefficient: is one that is found in a polynomial alone, that is, without multiplying the x or another unknown.

Example:  [tex]5x^{3} + 4x^{2} -99x +20[/tex]

In this case it is 20 because it is the one found without multiplying any linear term (x)
