What is the measure of ∠3 if c∥d ?

Answers

Answer:

72°

Step-by-step explanation:

Since c||d, ∠3 would be the same as ∠1

Since those two are supplementary angles, subtract 180 with 108 to get the measure of ∠1 which is 72°.

Since ∠1 and ∠3 are corresponding angles, they'll be congruent meaning ∠3 is also 72°.

:Cual es la solucion en notación decimal
de la ecuacion 4/3y-5=-6
Anota tu respuesta en el espacio provisto.​

Answers

For this case we must solve the following equation:

[tex]\frac {4} {3} y-5 = -6[/tex]

Adding 5 to both sides of the equation we have:

[tex]\frac {4} {3} y = -6 + 5[/tex]

Different signs are subtracted and the major sign is placed.

[tex]\frac {4} {3} y = -1[/tex]

We multiply by 3 both sides of the equation:

[tex]4y = -3[/tex]

We divide by 4 on both sides of the equation:

[tex]y = - \frac {3} {4}\\y = -0.75[/tex]

Thus, the solution of the equation is [tex]y = -0.75[/tex]

Answer:

[tex]y = -0.75[/tex]

Consider the function.
f(x) = -2/3x-24
Which conclusions can be drawn about f^-1(x)? Select two options.

Answers

Answer:

Statement 3

Step-by-step explanation:

y = -2/3x-24

Make x the subject

y + 24 = -(⅔)x

x = -(3/2)(y + 24)

Intersection variables

f^-1(x) = -(3/2)(x + 24)

Slope: -3/2

No domain restrictions

y-intercept: x = 0

-(3/2)(0+24)

-36

(0,-36)

x-intercepts: y = 0

0 = -(3/2)(x + 24)

x = -24

(-24,0)

Linear function, range is all real values of y

Answer:

[tex]f^{-1}(x)\: \textsf{ has a y-intercept of }\:(0,-36)[/tex]

[tex]f^{-1}(x)\: \textsf{ has a range of all real numbers.}[/tex]

Step-by-step explanation:

Given function

[tex]f(x)=-\dfrac{2}{3}x-24[/tex]

The given function has an unrestricted domain and range.

Domain:  (-∞, ∞)  →  all real numbersRange:  (-∞, ∞)  →  all real numbers

Inverse of a function

[tex]f^{-1}(x)[/tex] is the notation for the inverse of the function.  The inverse of a function is a reflection in the line y = x

Finding the inverse of the given function

Swap f(x) for y:

[tex]\implies y=-\dfrac{2}{3}x-24[/tex]

Rearrange the equation to make x the subject:

[tex]\implies -\dfrac{2}{3}x=y+24[/tex]

[tex]\implies -2x=3y+72[/tex]

[tex]\implies x=-\dfrac{3}{2}y-36[/tex]

Swap the x for [tex]f^{-1}(x)[/tex] and the y for x:

[tex]\implies f^{-1}(x)=-\dfrac{3}{2}x-36[/tex]

The inverse function has a slope of -3/2

The domain of the inverse function is the range of the function.

The range of the inverse function is the domain of the function.

Therefore, the domain and the range are unrestricted.

Domain:  (-∞, ∞)  →  all real numbersRange:  (-∞, ∞)  →  all real numbers

The y-intercept of the inverse function is when x = 0:

[tex]\implies f^{-1}(x)\: \textsf{ has a y-intercept of }\:(0,-36)[/tex]

The x-intercept of the inverse function is when y = 0:

[tex]\implies -\dfrac{3}{2}x-36=0[/tex]

[tex]\implies -\dfrac{3}{2}x=36[/tex]

[tex]\implies x=-24[/tex]

[tex]\implies f^{-1}(x)\: \textsf{ has a x-intercept of }\:(-24,0)[/tex]

Conclusion

[tex]f^{-1}(x)\: \textsf{ has a y-intercept of }\:(0,-36)[/tex]

[tex]f^{-1}(x)\: \textsf{ has a range of all real numbers.}[/tex]

In the right triangle shown, \angle B = 60^\circ∠B=60

angle, B, equals, 60, degrees and AB = 12AB=12A, B, equals, 12.
How long is ACACA, C?
Answer exactly, using a radical if needed.

Answers

The length of the side AC for the right triangle is 12√3 and the measure of angle C is equal to 30°.

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.

The basic trigonometric ratios includes;

sine, cosine and tangent.

Considering angle 60 for the right triangle with side AC opposite it we get;

tan 60 = AC/12 {opposite side/adjacent side}

√3 = AC/12

AC = 12 × √3 {cross multiplication}

AC = 12√3

angle C = 180 - (60 + 90) {sum of interior angles of a triangle}

angle C = 180 - 150

angle C = 30°.

Therefore, using the tangent of angles 60 we have the side length AC to be 12√3 and the measure of angle C is 30°.

Question:

In the right triangle shown below, angle B = 60° and side length AB = 12. How long is the side AC, and what is the size of angle C?

Answers

i like tacos:) thats the answer lol

The inequality for width(w) is 12[tex]\leq[/tex]w [tex]\leq[/tex] 33

What is inequality?

An inequality statement in algebra uses the inequality symbol to show the relationship between two expressions. On either side of an inequality sign, the expressions are not the same. It implies that the articulation on the left-hand side ought to be more noteworthy than or not exactly the articulation on the right-hand side or the other way around.

Given that a machine can roll a paper wide as 33feet and narrow as 12 feet

here we can say that 33 feet is the maximum limit of machine and 12 feet is minimum .

so the equation of width(w) should lie between 12 and 33 , so width can be greater or equal to 12 and less and equal to 33.

Hence the possible inequality is 12[tex]\leq[/tex]w [tex]\leq[/tex] 33

26.309932 MN  if gravity was normal gravity force and on basis salt water was 1030 kg/m3

Step-by-step explanation:

The rule below is something I just found.

To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity

Let f(x) = x² + x - 6 and g(x) = 3x - 6, what are f ⋅ g and f/g. state the resulting function and it's domain.

Answers

Answer:

[tex](f.g)(x) = 3x^3-3x^2-24x+36[/tex]

Domain of (f.g)(x) = All real numbers  

[tex](\frac{f}{g})(x) = \frac{x+3}{3}[/tex]

Domain of (f/g)(x) = All Real Numbers

Step-by-step explanation:

Given functions are:

[tex]f(x) = x^2+x-6\\g(x) = 3x-6[/tex]

We have to calculate f.g and f/g

In order to find f.g we have to multiply both functions

[tex](f.g)(x) = (x^2+x-6)(3x-6)\\= 3x(x^2+x-6) - 6(x^2+x-6)\\= 3x^3+3x^2-18x-6x^2-6x+36\\= 3x^3+3x^2-6x^2-18x-6x+36\\=3x^3-3x^2-24x+36[/tex]

The domain of (f.g)(x) is all real numbers

Now

[tex](\frac{f}{g})(x) = \frac{f(x)}{g(x)}\\= \frac{x^2+x-6}{3x-6}\\=\frac{x^2+3x-2x-6}{3x-6}\\=\frac{x(x+3)-2(x+3)}{3(x-2)}\\=\frac{(x+3)(x-2)}{3(x-2)}\\=\frac{x+3}{3}[/tex]

The domain of (f/g)(x) is all real numbers.

Hence,

[tex](f.g)(x) = 3x^3-3x^2-24x+36[/tex]

Domain of (f.g)(x) = All real numbers  

[tex](\frac{f}{g})(x) = \frac{x+3}{3}[/tex]

Domain of (f/g)(x) = All Real Numbers
