Step-by-step explanation:

180-53-97

Given:

The given function is:

[tex]f(x)=11x-11[/tex]

To find:

The value of [tex](f\circ f^{-1})(-11)[/tex].

Solution:

We have,

[tex]f(x)=11x-11[/tex]

First we have to find the inverse of this function.

Putting f(x)=y, we get

[tex]y=11x-11[/tex]

Interchange x and y.

[tex]x=11y-11[/tex]

Isolate the variable y.

[tex]x+11=11y[/tex]

[tex]\dfrac{x+11}{11}=y[/tex]

[tex]y=\dfrac{x+11}{11}[/tex]

Putting [tex]y=f^{-1}(x)[/tex], we get

[tex]f^{-1}(x)=\dfrac{x+11}{11}[/tex]

Now,

[tex](f\circ f^{-1})(-11)=f(f^{-1}(-11))[/tex]

[tex](f\circ f^{-1})(-11)=f\left(\dfrac{-11+11}{11}\right)[/tex]        [tex]\left[\because f^{-1}(x)=\dfrac{x+11}{11}\right][/tex]

[tex](f\circ f^{-1})(-11)=f\left(\dfrac{0}{11}\right)[/tex]

[tex](f\circ f^{-1})(-11)=f\left(0\right)[/tex]

The given function is [tex]f(x)=11x-11[/tex].

[tex](f\circ f^{-1})(-11)=11(0)-11[/tex]

[tex](f\circ f^{-1})(-11)=-11[/tex]

Therefore, the value of [tex](f\circ f^{-1})(-11)[/tex] is [tex]-11[/tex]. Hence the correct option is A.

Answer:

[tex] {eb}^{2} = {ab}^{2} + {ea}^{2} \\ {ab}^{2} = {eb}^{2} - {ea}^{2} \\ {ab}^{2} = {20}^{2} - {12}^{2} \\ ab = 16 \\ \\ {db}^{2} = {bc}^{2} + {dc}^{2} \\ {bc}^{2} = {db}^{2} - {dc}^{2} \\ {bc}^{2} = {20}^{2} - {16}^{2} \\ bc = 12 \\ \\ so \: ac = ab + bc \\ ac = 28[/tex]

As we know that,

[tex]\bigstar \: \boxed{\sf {Area_{(Trapezium)} = \dfrac{1}{2} \times ( a + b) \times h}} \\ [/tex]

Substituting values, we get :

[tex] \longmapsto [/tex] Area = [tex]\sf \dfrac{1}{2} [/tex] × ( 60 + 40 ) × 30 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = [tex]\sf \dfrac{1}{2} [/tex] × 100 × 30 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 1 × 100 × 15 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 100 × 15 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 1500 ft[tex] \sf ^2 [/tex]

Answer:

The quadrilateral is a rhombus

Step-by-step explanation:

Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) Is a rhombus

A rhombus is a quadrilateral with all its sides equal to each other.

We prove this using the formula

√(x2 - x1)² + (y2 - y1)²

When given vertices (x1, y1) and (x2, y2)

For sides PL

P(-2, 3) L( 2, 6)

√(2 - (-2))² + (6 - 3)²

= √4² + 3²

= √16 + 9

= √25

= 5 units

For sides LU

L( 2, 6) U (7,6)

√(7 - 2)² + (6 - 6)²

= √5²

= √25

= 5 units

For side US

L( 2, 6) U (7,6)

= √(7 - 2)² + (6 - 6)²

= √5² + 0²

= √25

= 5 units

P(-2, 3), S(3, 3)

= √(3 - (-2))² + (3 - 3)²

= √5² + 0²

= √25

= 5 units

From the above calculation,

PL = LU = US = PS = 5 units

Hence, the above quadrilateral is a rhombus

Answer:

Step-by-step explanation:

GIVEN :-

TO PROVE :-

CONSTRUCTION :-

FACTS TO KNOW BEFORE SOLVING :-

PROCEDURE :-

∠QPR + ∠QOR = 180°

⇒ ∠QOR = 180° - ∠QPR

In ΔQOR , OQ = OR (∵ Radii of the circle are equal)

⇒ ΔQOR is an isosceles triangle (∵ OQ = OR i.e. two sides of the triangle are equal.)

⇒ ∠OQR = ∠ORQ (∵ In an isosceles triangle , the base angles are equal)

So,

∠QOR + ∠OQR + ∠ORQ = 180°

⇒ ∠QOR + 2∠OQR = 180°  (∵ ∠OQR = ∠ORQ)

⇒ 180° - ∠QPR = 180° - 2∠OQR  (∵ ∠QPR + ∠QOR = 180°)

⇒ -∠QPR = -2∠OQR  (∵ Cancelling 180° from both the sides.)

⇒ ∠QPR = 2∠OQR (Proved)

Answer:

94° and 86°

Step-by-step explanation:

'x-8' = smaller angle

'x' = larger angle

x - 8 + x = 180

2x = 188

x = 94

94 - 8 = 86

Answer:

slope = - [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{5}{3}[/tex] x + [tex]\frac{3}{4}[/tex] ← is in slope- intercept form

with slope m = - [tex]\frac{5}{3}[/tex]

they leave a tip of $1.20, the total would be $9.20

Answer:

$9.2

Step-by-step explanation:

Four friends spend 8 dollars. However, they also leave a 15% tip. So, you will have to multiply .15 by 8. However that is not it. After, you have to add the product of that with 8. Which will give you 9.2.

Answer:

Option A 1/2x³ is your answer

Answer:

Step-by-step explanation:

Answer:

59.7°

Step-by-step explanation:

Working based on the solution diagram :

The angle of elevation = x

From trigonometry :

Opposite side = 12 feets

Adjacent side = 7 feets

Tan x = opposite / Adjacent

Tan x = 12 / 7

Tan x = 1.7142857

x = tan^-1(1.7142857)

x = 59.744°

The angle of elevation from the duck is 59.7°
