Answer:

The height of the hovercraft at the time of takeoff is  33  meters.

Step-by-step explanation:

Height of hovercraft  x  seconds after takeoff  =  h(x)  =  -(x - 11)(x + 3)

Height after takeoff is  =  h(0)  =  -(0 - 11)(0 + 3)  =  -(-11)(3)  =  33

So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.

Answer: 33  meters.

The equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]

In a standard deck of cards, there are:

Ace = 4

Cards = 52

So, the probability of selecting an ace is:

[tex]p = \frac{4}{52}[/tex]

Simplify

[tex]p = \frac{1}{13}[/tex]

The probability of not selecting an ace is calculated using the following complement rule

[tex]q = 1 - \frac{1}{13}[/tex]

Simplify

[tex]q =\frac{12}{13}[/tex]

The expected value is then calculated as:

[tex]E(x) = \sum x * P(x)[/tex]

This gives

[tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]

Hence, the equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]

The equivalent quotient of the expression √16 / √8 are as follows:

√16 / √8

√16 = 4

Therefore,

√16 / √8 = 4 / √8 = 4 / 2√2 = 2 / √2

2 / √2 × √2 / √2 = 2√2 / 2 = √2

Answer:

32 degrees.

Step-by-step explanation:

So every triangle =180 degrees.

Firstly, 14 + 45 = 59

Secondly, 180 - 59 = 121

so angle AEB = 121 degrees.

Using vertical angles theorum, angles AEB and CED are equal to each other

so CED = 121 degrees.

121 + 27 = 148

then 180 - 148 = 32

Angle D = 32 degrees

Step-by-step explanation:

The following information is missing:

The hypotenuse of that triangle is 13√2 ft.

The 45°- 45°- 90° triangle theorem states that the length of the hypotenuse is √2 times the length of the legs. This means that, in this case, the length of the legs are 13 ft. One of the legs is the height of the wall.

Answer:

65°

Step-by-step explanation:

∠1=115°

∠2=65°

∠3=65°

∠4=115°

∠5=115°

∠6=65°

∠7=115°

∠8=65°

We get this because Line m and l are parallel. Also ∠1+∠2=180° so if ∠1 is 115°, then ∠2 is 180°-115° or 65°.

Good luck on your assignment

Answer:

0.52

Step-by-step explanation:

→The formula for the volume of a cone is:

V = π[tex]r^2\frac{h}{3}[/tex]

→The "r," (radius) is half the diameter (1), so it's 0.5:

V = π[tex]0.5^2\frac{2}{3}[/tex]

V = 0.52

Answer:

9x + 25 + 3x = 34 + 54

9x + 3x = 12x

34 + 54 = 88

12x + 25 = 88

      - 25    - 25

12x = 63

x = 5.25

Answer:

x = 21/4 = 5 1/4

Step-by-step explanation:

9x +25+3x = 34 + 54

Combine like terms

12x+25 = 88

Subtract 25 from each side

12x+25-25 = 88-25

12x =63

Divide by 12

12x/12 = 63/12

x = 21/4

Answer:

[tex]30 {in}^{2} [/tex]

Step-by-step explanation:

First we have to find the value of the other leg of the triangle. To find that we can use the PYTHAGORAS theorem because this is an right triangle.

[tex] {h}^{2} = {p}^{2} + {b}^{2} \\ {13}^{2} = {12}^{2} + {b}^{2} \\ 169 = 144 + {b}^{2} \\ 169 - 144 = {b}^{2} \\ 25 = {b}^{2} \\ b = \sqrt{25 } \\ b = 5 \: \: in[/tex]

Now let's find the area.

[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 5 \times 12 \\ = \frac{60}{2} \\ = 30 {in}^{2} [/tex]

Answer:

We add 11 to each side to get rid of -11 so x = -18 + 11 = -7.

Answer:

x = -7

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Add 11 to both sides:

x + (-11) = -18

x - 11 = -18

x - 11 (+11) = -18 (+11)

x = -18 + 11

Simplify. Combine like terms:

x = -18 + 11

x = -7

x = -7 is your answer.
