Answer:

  1.13 feet

Step-by-step explanation:

We know that the sine relation is ...

  Sin = Opposite/Hypotenuse

so the length (L) of the ramp surface will be ...

  sin(angle) = 2/L

  L = 2/sin(angle)

For 18°, the ramp length will be about ...

  L = 2/sin(18°) ≈ 6.472 . . . . feet

For 22°, the ramp length will be about ...

  L = 2/sin(22°) ≈ 5.339 . . . . feet

The difference in lengths is about ...

  6.472 -5.339 = 1.133 ≈ 1.13 . . . . feet

When a certain basketball player takes his first shot in a game he succeeds with prob. 1/3. If he misses his first shot, he loses confidence and his second shot will go with prob. 1/4. If he misses his first 2 shots, his third shot will go with pro. 1/5. If he misses his first 3 shots, his fourth shot will go with prob. 1/6. If he misses his first 4 shots, the coach will remove hom from the game. Assume that the player keeps shooting until he succeeds or he is removed from the game. Let X denote the number of shots he misses until his first success or until he is removed from the game.

Required:
a. Compute the p.m.f. of X
b. Compute E[X]

Answers

Answer:

X : ____ 0 ____1 ____ 2 ____ 3 ____ 4

P(x) : _ 0.333_0.167 _0.100_0.067__0.333

E(X) = 1.9

Step-by-step explanation:

From the question above:

X ; number of misses

For :

X = 0 ; P(X = 0) = 1/3 = 0.333

X = 1 ; misses first ; succeeds on second

P(X = 1) = 2/3 * 1/4 = 2/12 = 1/6 = 0.167

X = 2 ; misses first, misses second, succeeds on third

P(X = 2) = 2/3 * (1 - 1/4) * 1/5 = 2/3*3/4*1/5 = 6/60 = 1/10 = 0.10

X = 3 :misses first, misses second, misses third succeeds on fourth

P(X = 3) = 2/3 * 3/4 * (1 - 1/5) * 1/6 = 2/3*3/4*4/5*1/6 = 24/360 = 0.067

X= 4

P(X =4) = 2/3 * 3/4 * 4/5 * 5/6 = 120/ 360 = 1/3 = 0.333

X : ____ 0 ____1 ____ 2 ____ 3 ____ 4

P(x) : _ 0.333_0.167 _0.100_0.067__0.333

E(X) :

Σx*p(x) = (0*0.333) + (1*0.167) + (2*0.100) + (3*0.067) + (4*0.333)

0 + 0.167 + 0.2 + 0.201 + 1.332

= 1.9

f(2)=−14 and g(2)=13 Find (f+g)(2).

Answers

Answer: The value of (f+g)(2) = -1

Step-by-step explanation:

Given: f(2)=-14 and g(2)=13

To find: (f+g)(2)

Addition of two functions:

(f+g)(x) = f(x)+g(x)

Then, (f+g)(2) = f(2)+g(2)

(f+g)(2)  = -14+13  [given]

(f+g)(2)  = -1

Therefore , the value of (f+g)(2) = -1

Step-by-step explanation:

The expression is for the interior angle of the hexagon; one interior angle is equal to .

Since an interior angle of a hexagon measures 120°, we have the equality

.

Now it is just a matter of solving for  

11x=120-21

11x=99

x=99/11

x=9

The value of {x} for the hexagon shown is 9.

What is Hexagon?

A hexagon is a polygon with 6 equal sides. The perimeter of a hexagon is the sum of all the six lengths. The measure of the interior angle of a hexagon is 120 degrees.

Given is to find the value of {x} in the Hexagon shown below.

The measure of the internal angle of a hexagon is 120 degrees. So, we can write -

(11x + 21) = 120

11x = 120 - 21

11x = 99

x = 9

Therefore, the value of {x} for the hexagon shown is 9.

First input: (7.6, 9.3)


Second input: (10.5, -2.1)

Answers

Answer:

[tex](-0.6,12.9)[/tex]

[tex](2.3,1.5)[/tex]

Step-by-step explanation:

Given:  For one part of the game, Jonny uses the  rule [tex](x,y)[/tex] → [tex](x-8.2,y+3.6)[/tex] to move objects on the screen.

To find: outputs for the given inputs

Solution:

Given rule is [tex](x,y)[/tex] → [tex](x-8.2,y+3.6)[/tex]

Put the first input as [tex](x,y)=(7.6,9.3)[/tex]

Output is [tex](x-8.2,y+3.6)=(7.6-8.2,9.3+3.6)=(-0.6,12.9)[/tex]

Given rule is [tex](x,y)[/tex] → [tex](x-8.2,y+3.6)[/tex]

Now, put input the second input as [tex](x,y)=(10.5,-2.1)[/tex]

Output is [tex](x-8.2,y+3.6)=(10.5-8.2,-2.1+3.6)=(2.3,1.5)[/tex]

Answer:

(-3.2 , 12.3)

(0.7 , 3.6)

The rule :

(x, y)→(x−7.5, y+6.8)

For the x - coordinate ; Subtract 7.5

For the y - coordinate `; add 6.8

First input : (4.3, 5.5)

Output :

x = 4.3 - 7.5 = - 3.2

y = 5.5 + 6.8 = 12.3

Output = (4.3, 5.5) →(-3.2 , 12.3)

Second input : (8.2, -3.2)

Output :

x = 8.2 - 7.5 = 0.7

y = - 3.2 + 6.8 = 3.6

Output = (8.2, -3.2)→(0.7 , 3.6)

The outputs obtained are :

(-3.2 , 12.3) and (0.7 , 3.6)

What is the slope of a line parallel to the line whose equation is 6x - y = 1. Fully
reduce your answer.

Answers

Answer:

6x

Step-by-step explanation:

To find a parallel line, you will need to put everything into the slope intercept form(y=mx+b).

When you do this, you should get -y=-6x+1. You cannot have a negative y, so you will divide everything by -1 to get y=6x-1.

Two lines are parallel when their slope is the same. The slope in this equation is 6.

For the function f(x) = -3sin(x) + 2, the distance between the maximum and minimum values is 6. Which statement must be true about this function? HINT: It's not B.

A. The amplitude is 3.
B. The midline is y = 3.
C. The period of the function is 3pi.
D. The range is [-3, 3].

Answers

Answer: A. The amplitude is 3.

Step-by-step explanation:

Given function : [tex]f(x) = -3sin(x) + 2[/tex]

Period of a sine function is [tex]2\pi.[/tex]

Since [tex]-1\leq \sin x \leq 1[/tex]

[tex]\Rightarrow\ -3\leq -3\sin x\leq 3\\\\\Rightarrow\ -3+2\leq -3\sin x+2\leq 3+2\\\\\Rightarrow\ -1\leq -3\sin x+2\leq 5[/tex]

i.e. Range is [-1,5]

Amplitude = 3 [coefficient of sin x]

1. What is solution to 0.2(6x - 12) = 0.3(6 - 4x)

Answers

Answer:

x = 1.75

Explanation:

0.2(6x - 12) = 0.3(6 - 4x)

Simplify both sides of the equation

0.2(6x − 12) = 0.3(6 − 4x)

(0.2)(6x) + (0.2)(−12) = (0.3)(6) + (0.3)(−4x) (Distribute)

1.2x + −2.4 = 1.8 + −1.2x

1.2x − 2.4 = −1.2x + 1.8

Add 1.2x to both sides

1.2x − 2.4 + 1.2x = −1.2x + 1.8 + 1.2x

2.4x − 2.4 = 1.8

Add 2.4 to both sides

2.4x − 2.4 + 2.4 = 1.8 + 2.4

2.4x = 4.2

Divide both sides by 2.4

2.4x / 2.4 = 4.2 / 2.4

x = 1.75

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.

Answers

Answer:

r = 7

Step-by-step explanation:

You first need to know the formula for area of a circle. It is:

Area = π*r^2 (π = pi, r = radius)

Plug in for the given values:

153.86 = 3.14 * r^2

49 = r^2 (Divided both sides by 3.14)

r = 7

The region outside the circle is under the consideration. Then the correct option is B.

What is an equation of a circle?

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x – h)² + (y – k)² = r²

The inequality equation of the graph is given below.

(x – 3)² + (y + 4)² > 36

(x – 3)² + (y + 4)² > 6²

From the equation, the radius of the circle will be 6 units and the center of the circle will be (3, –4).

The region outside the circle is under the consideration.

Then the correct option is B.

The graph is given below.
