Answer:

The answer is : Collision

Step-by-step explanation:

Alex would have to pay collision deductible before he receives a payment from the insurance company.

A deductible is any amount that you have to pay out of pocket when you make a claim.

Collision deductible comes to effect when your vehicle is damaged in an accident. This pays the cost of repairing the vehicle minus the amount of your deductible.

Answer:

18 racks

Step-by-step explanation:

338/19=17.78 so if you round up you get 18 racks

Ms. Sanchez needs to buy 18 coat racks to accommodate 338 coats, as each rack holds 19 coats and we round up the result of the division 338/19 to the nearest whole number.

The question asks us to determine how many coat racks Ms. Sanchez should buy if she wants to hold 338 coats and each rack holds 19 coats. To find out the number of racks needed, we divide the total number of coats by the number of coats that one rack can hold, which is a straightforward division problem.

We calculate this by dividing 338 (the total number of coats the racks need to hold) by 19 (the number of coats each rack can hold):

338 / 19 = 17.7895...

Since we cannot have a fraction of a coat rack, we round up to the nearest whole number because Ms. Sanchez needs enough racks to hold all the coats, and you cannot purchase a fraction of a rack. Therefore, Ms. Sanchez should buy 18 coat racks to accommodate all 338 coats.

Answer:

f^-1 = 4(x-3)

Step-by-step explanation:

If f(x) = 1/4(x) + 3 we ned to find f^-1.

To find the inverse function, we need to solve the equation for "x", as follows:

f(x) = 1/4(x) + 3

y = 1/4(x) + 3

y-3 = 1/4(x)

4(y-3) = x

Now, change the "x" for an "y". And change the "y" for an "x":

4(x-3) = y

The solution is the last one.

Answer:  The correct option is

(A) The scale factor is 0.8 and the coordinates of point B" are (–3.2, –4.8).

Step-by-step explanation:  Given that the segment AB is being dilated to A''B'' with the center at the origin. The image of A, point A" has coordinates of (3.2, 6.4).

We are to find the scale factor of the dilation and the co-ordinates of the point B''.

From the given graph, we note that

the co-ordinates of point A are (4, 8).

Now, If S is the scale factor of dilation, then we must have

[tex]S\times (4,8)=(3.2,6.4)\\\\\Rightarrow (4S,8S)=(3.2,6.4)\\\\\Rightarrow S=\dfrac{3.2}{4}=\dfrac{6.4}{8}=0.8.[/tex]

So, the scale factor is 0.8.

Now, the co-ordinates of point B are (-4, -6). So, the co-ordinates of B'' will be

[tex](-4\times 0.8,-6\times 0.8)=(-3.2,-4.8).[/tex]

Thus, the correct option is

(A) The scale factor is 0.8 and the coordinates of point B" are (–3.2, –4.8).

Answer:

A) The scale factor is 0.8 and the coordinates of point B" are (–3.2, –4.8).

[tex]y= \frac{ - 20}{5} = - 4[/tex]

The point is

[tex]( - \frac{23}{5} , - 4)[/tex]

The coordinates of the point on the directed line segment PQ that partitions it in the ratio 3/2 are (-21/5, -17/5).

To find the coordinates of the point on the directed line segment PQ that partitions it in the ratio 3/2, we can use the section formula. The section formula states that the coordinates of a point dividing a line segment with endpoints (x1,y1) and (x2,y2) in the ratio m:n are given by:

x = (m*x2 + n*x1)/(m+n)

y = (m*y2 + n*y1)/(m+n)

Plugging in the values from the given points P(2,-1) and Q(-9,-6) into the formula, we get:

x = (3*(-9) + 2*2)/(3+2) = -21/5

y = (3*(-6) + 2*(-1))/(3+2) = -17/5

So, the coordinates of the point are (-21/5, -17/5).

The pentagon is translated 1 unit to the left, so the points move to the left by 1 unit. Moving left or right changes the x value, when you move right, the x value increases, when you move left, x decreases. Since x is going left 1 unit:

So x - 1

10 units down. Moving up down or up changes the y value, when you move down, y decreases, when you move up, y increases. Since the pentagon is going down 10 units:

y - 10

Your answer is A

The rule that describes the given transformation is (x, y) → (x - 1, y - 10). It is given that the pentagon is translated by 1 unit to the left and 10 units down.

The graph is transformed into a new graph by applying certain operations like,

It is given that a pentagon in the graph is translated as 1 unit to the left and 10 units to the down.

Here the translation is towards the negative axes.

So, the rule for this transformation we can write as (x, y) → (x - 1, y - 10)

Translating the points of the pentagon from the graph using this rule:

Actual coordinates                        Translated coordinates

(-1, 3)                                                 ((-1 - 1), (3 - 10)) = (-2, -7)

(1, 5)                                                  ((1 - 1), (5 - 10)) = (0, -5)

(2, 2)                                                 ((2 - 1), (2 - 10)) = (1, -8)

(4, 6)                                                 ((4 - 1), (6 - 10)) = (3, -4)

(5, 3)                                                 ((5 - 1), (3 - 10)) = (4, -7)

So, the new pentagon will be plotted in the graph with these translated coordinates.

The graph of the translated pentagon is shown below.

Answer:

It's the first choice (20 degrees).

Step-by-step explanation:

These angles will be equal ( by The Alternate Angle Theorem).

5(x - 2) = x + 14

5x - 10 = x + 14

4x = 24

x = 6.

So the measure of each angle =  5(6 - 2) = 6 + 14 = 20 degrees.

The angles of elevation and depression are equal because they are alternate interior angles. Solving the given expressions yields x = 6. Therefore, both the angle of elevation and the angle of depression measure 20 degrees.

First, let's set up the problem:

In any scenario involving angles of elevation and depression, these angles are equal because they are alternate interior angles formed by a horizontal line and a transversal.

Therefore, we can equate the two expressions:

5(x-2) = (x+14)

Now, solve for x:

Now substitute x back into the expressions to find the angle measures:

For the angle of elevation: 5(x-2) = 5(6-2) = 5*4 = 20 degrees

For the angle of depression: (x+14) = (6+14) = 20 degrees

Therefore, both the angle of elevation and the angle of depression measure 20 degrees.

This confirms that our setup and calculation are correct.

Answer:

  you expect to win on average $1.33 per round

Step-by-step explanation:

The expected value is the sum of products of probability and value:

  2/6×$8 + 4/6×(-$2) = $8/3 - 4/3 = $4/3 ≈ $1.33

The expected value of the gambling game is calculated by taking into account the probability of winning $8 and losing $2. The final expected value is $1.33, which means on average, you would gain $1.33 per game played.

To calculate the expected value for the gambling game where you roll a die, you need to account for the different outcomes and their associated probabilities. In this game, rolling a 1 or 2 means you win $8, and there are two outcomes out of six that result in a win, giving a probability of 2/6 or 1/3 for each of these outcomes. Rolling any other number (3, 4, 5, or 6) results in losing $2, with a probability of 4/6 or 2/3 for each of these losing outcomes.

The expected value (EV) can be calculated using the formula:

EV = (Probability of Winning × Amount Won) + (Probability of Losing × Amount Lost)

Substituting the values into the formula:

EV = ‎‎(1/3 × $8) + (2/3 × -$2)

EV = ($2.67) + (-$1.33)

EV = $1.33

This means that the average gain per game, after many plays, is expected to be $1.33.

Answer:

34.7 degrees

Step-by-step explanation:

This is a right triangle trig problem. The angle in question, the angle of elevation, is the base angle that is NOT the right angle. The height of the tree is the side opposite the angle of elevation, and the distance away from the tree is the measure of the base of the right triangle. So the question, then, is "What is the angle that has a ratio equal to the side opposite the angle over the side adjacent to the angle?" This is the definition of the tangent of an angle. The equation will be set up as follows:

[tex]tan\beta =\frac{45}{65}[/tex]

Your calculator needs to be in degree mode when you do this operation. Press 2nd on your calculator then tan and you'll get tan^-1 on your display. This means you are looking for a missing angle. Enter the fraction as 45/65 inside the parenthesis and hit enter and you'll get an angle of 34.69515353. Round to the nearest tenth for 34.7

You will always use the 2nd and sin/cos/tan buttons to find missing angles.

The angle elevation is 34.6 9 degree.

When it lies between the horizontal line and the line of sight, the angle of elevation is formed. The angle that forms when the line of sight is above the horizontal line is referred to as the angle of elevation. The line of sight, however, is to the horizontal line downward in the angle of depression.

The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.

Given:

Height of tree= 45 foot

Distance= 65 feet

Now, Using Trigonometry

tan [tex]\theta[/tex] = P/ B

        = 45/65

        = 9/ 13

        = 0.6923

[tex]\theta[/tex] = 34.69 degrees.

Step-by-step explanation:

Ok, in a normal year, the 220th day is the 8 of august, that is 08-08.

So, using x=220, we can estimate the number of daylight hours in that city:

[tex]y=2.15sin(\frac{2\pi }{12}x)+10= 2.15sin(\frac{2\pi }{12}(220))+10[/tex]

Then using a calculator in radians:

[tex]y=2.15(sin(0,524*220))+10[/tex]

[tex]y=2.15(sin(115.192))+10[/tex]

[tex]y=2.15(0,866)+10[/tex]

[tex]y=1.862+10[/tex]

[tex]y=11.862[/tex]

Then, you have that is 11 hours, but what about the 0.862 hours? We convert the to hours knowing that 1 hour has 60 minutes. Then 0,862*60 minutes= 51,72 minutes. And we do this for the 0,72 minutes as well, knowing that 1 minute has 60 seconds, then 0,72*60= 44 seconds.

The number of hours is 11 hours, 51 minutes and 44 seconds
