Answer:

The object has fallen [tex] \boxed{\sf 289} [/tex] feet from ts intial position.

Step-by-step Explanation:

Given:

Formula:

[tex] \rm v = \sqrt{2gh} [/tex]

Where,

v = velocity (in feet per second)

h = Height fallen (in feet)

g = acceleration due gravity (in feet per second squared) = approximately 32 ft/s²

To find:

How far an object has fallen if its velocity (v) is 136 ft/s

Solution:

By substituting the value of g & v in the formula we get:

[tex]\rm \implies 136 = \sqrt{2 \times 32 \times h} \\ \\ \rm \implies 136 = \sqrt{64h} \\ \\ \rm \implies 64h = {136}^{2} \\ \\ \rm \implies h = \dfrac{ {136}^{2} }{64} \\ \\ \rm \implies h = \dfrac{18496}{64} \\ \\ \rm \implies h = 289 \: ft[/tex]

Answer:

x = 20

Step-by-step explanation:

We know that a straight line is 180 degrees. We also know that the line A and B is a supplementary angle.

We subtract 180 - 110 which will come out to 70 which is the value of angle B

We know that angles D and E are 90 degrees and since D and C is 180 degrees, that means C and E is equal to 90 degrees as well.

Since B is equal to 70 degrees, we subtract 90 - 70 to get 20 degrees which is the value of x

The length of XN is 6

Calculation

By angle bisector theorem

Answer:

  (9, 7)

Step-by-step explanation:

You want the coordinates of the image of point (9, -7) after it has been reflected across the x-axis.

The image point will be as far above the x-axis as the original point is below the x-axis. The y-coordinate of -7 tells you the point is 7 units below the x-axis. The reflected point will be 7 units above the x-axis, so will have a y-coordinate of +7.

The image coordinates are (9, 7).

Reflection across the x-axis changes the sign of the y-coordinate.

Step-by-step explanation:

If the doors for the small cabinets are 17.5 in long, and the doors for the large cabinets are 3.5 times longer, find the length of the large cabinet doors by multiplying the length of the small cabinet doors by 3.5:

⇒ Length of large cabinet doors = 17.5 × 3.5 = 61.25 in

1 foot = 12 inches

⇒ 12 foot = 12 × 12 = 144 inches

To find how many large doors can be cut from a board that is 12 feet long, divide 144 inches by the found length of the large door:

⇒ 144 ÷ 61.25 = 2 r 21.5

Therefore, 2 large doors can be cut from a board that is 12 feet long.

(There will be 21.5 inches of board left over).

Segment QR is the included segment to ∠PQR and ∠PRQ, which are each congruent to ∠PAB and ∠PBA, respectively in ΔPAB and segment AB is the included side to ∠PAB and ∠PBA, therefore, the line segment on triangle ΔPAB that corresponds to line segment QR is segment AB

Part C: Angle ∠Q on triangle ΔPQR is adjacent to segment QR on the right and angle ∠P on the left, while angle ∠A is adjacent segment AB on the right and ∠P on the right, segment AB in ΔPAB corresponds to segment QR on triangle ΔPQR, therefore, by the relative position of angle ∠A on triangle ΔPAB, it is the angle that corresponds to angle ∠Q

Where:

Based on all the given facts, the primitive absolute value function (f'(x) = |x|) is translated horizontally 3 units in the +x direction and vertically 5 units in the +y direction. If we know that a = 3 and b = 5, then we find the absolute value function y = |x - 3| + 5, whose representation is shown below.

The probability distribution is a) discrete, with b) a mean of 1.23, the standard deviation is c) 0.6458, d) the probability that an American will take 3 or more trips is 0.04, e) the probability that an American will take 2 or less trips is 0.96 and, f) the probability to take at least one trip is 0.94

It is given that the probability distribution of the no. of trips an American adult takes that lasts 5 nights or more

x              probability

0                  0.06

1                   0.70

2                  0.20

3                  0.03

4                  0.01

a)

Here we can see that all the values are isolated and there is no continuity between them. The distribution clearly has breaks between them.

Hence, we can say that the distribution is discrete.

b)

The expected value of any probability

E(X) = ∑xp(x)

where,

x is the random variable

p(x) is the probability of the corresponding random variable hence we get

E(X) = 0 × 0.06  +  1 × 0.70  +  2 × 0.20  +  3 × 0.03  +  4 × 0.01

= 0  +  0.7  +  0.4  +  0.09  +  0.04

= 1.23

Hence the expected value is 1.23

c)

The standard deviation is √σ²

Where σ² = variance of the distribution

σ² = E(X²) - {E(X)}²

{E(X)}² = 1.23²

= 1.5129

E(X²) = ∑x²p(x)

= 0 × 0.06  +  1 × 0.70  +  4 × 0.20  +  9 × 0.03  +  16 × 0.01

= 0.7  +  0.8  +  0.27  +  0.16

= 1.93

Therefore,

σ² = 1.93  -  1.5129

= 0.4171

Therefore

σ = 0.6458

d)

The probability to take 3 or more trips is

P(X≥3)

= P(X = 3)  +  P(X = 4)

= 0.03 + 0.01

= 0.04

e)

The probability of an American taking 2 or less trips is

1 - P(X≥3)

= 1 - 0.04

= 0.96

f)

The probability that an American will take at least one trip is

P(X≥1)

= 1 - P(X = 0)

= 1 - 0.06

b. The probability of getting a $2 winner will be

1/10 = 0.1

c. The probability of getting no $5 winner is (49/50)^50 = 0.36

So the probability of getting $5 winner will be 1 - 0.37 = 0.64

d. The probability of getting no $10 winner is (499/500)^500 = 0.37

Answer: 7/6

Step-by-step explanation:

Ok so first we must take these fractions and make them have a common denominator. The best way to do this is to take 2/3 and multiply the numerator and denominator by 8 giving us 16/24. Next take 4/8 and multiply the numerator and denominator by 3 giving us 12/24. Now we have both a common denominator. Now we add the numerators of both (16+12) to get 28/24 but now we have an improper fraction divide the numerator and denominator by 4 to get us 7/6.

Answer:

138° (nearest degree)

Step-by-step explanation:

Bearing:  The angle (in degrees) measured clockwise from north.

The given scenario can be modelled as a right triangle (see attachment).

Therefore, the bearing is 90° + θ (shown in green on the attached diagram).

To find angle θ, use the cosine trigonometric ratio:

[tex]\implies \cos{\theta}=\dfrac{A}{H}[/tex]

[tex]\implies \cos{\theta}=\dfrac{624}{927}[/tex]

[tex]\implies \theta=\cos^{-1}\left(\dfrac{624}{927}\right)[/tex]

[tex]\implies \theta=47.69018863...[/tex]

[tex]\implies \theta=48^{\circ}\; \; \sf (nearest\;degree)[/tex]

Therefore, the bearing of the drawbridge from the tower is:

[tex]\begin{aligned}\implies \sf Bearing&=90^{\circ}+\theta\\&=90^{\circ}+48^{\circ}\\&=138^{\circ} \end{aligned}[/tex]

Answer:

-----------------------------

Add 90° to the angle measure we just found, since bearing is counted from the north direction:

False, As the sample size is increased, the standard deviation of a sampling distribution of the sample's mean drops.

The term "standard error" also refers to the sample mean's standard deviation. The high dimensionality theorem establishes that as sample size increases, the sample mean's sampling distribution becomes more or less normal.

Using the formula below, the sample mean's standard deviation is determined.

σ ÷ √n

where n is the sample size and would be the population standard deviation.

As the denominator, or n, increases, the standard variance of the sample average would also decrease, as shown by the aforementioned calculation.

It follows that the standard deviation of a sample's average decreases as the sample size grows.

Answer:

The measure of its supplementary angle is 18.6 degrees

Step-by-step explanation:

A Supplementary angle is any two angles that sum up to 180 degrees

With this in mind we can subtract 180 - 161.4 to get the measure of the other angle.

Since 161.4 + 18.6 = 180 this is correct

Answer: The supplementary angle to 161.4 degrees is 18.6 degrees.

Step-by-step explanation: the sum of two supplementary angles is always 180 degrees.

180-161.4 is equal to 18.6 degrees.

Solving for g in the equation g =  (c - p)/0.325

An equation is a mathematical expression that show the relationship between two variables.

Since we are given the equation c = 0.325g + p, we desire to make g subject of the formula.

To do this, we perform some mathematical operations on it.

So, c = 0.325g + p

Now, to isolate 0.325g on the right hand side, we subtract p from both sides of then equation.

So, c = 0.325g + p

c - p = 0.325g + p - p

c - p = 0.325g

Now to isolate g, we divide both sides of the equation by 0.325. So, we have

c - p = 0.325g

(c - p)/0.325 = 0.325g/0.325

g = (c - p)/0.325

So, we have g =  (c - p)/0.325
