Answer: (10,5) or (14,3) are two possible answers.
Infinitely many answers are possible. Pick one to write as the final answer to your teacher.
=====================================================
Explanation:
Focus on the points B(1,4) and C(5,2)
More specifically, focus on the x coordinates 1 and 5. To go from B to C, we move to the right 4 units since 1+4 = 5
We also move down 2 units since we go from y = 4 to y = 2
In short, the translation motion is "right 4, down 2". We can further abbreviate this into the vector notation <4, -2>. This translation vector only applies going from B to C.
The vector notation <4,-2> is the same as writing [tex](x,y) \to (x+4,y-2)[/tex] but the first method is much faster to write out since it avoids needing to write x or y.
--------------------
Now if we want to construct a similar triangle A'B'C', we will use that vector to scale it up or down. Let's scale it up and double each coordinate.
<4, -2> doubles to <8,-4>
So instead of "right 4, down 2" we now follow the path "right 8, down 4". Take notice how both motions involve the same slope.
Start at B'(2,9) and move right 8 and down 4 to arrive at C'(10,5)
See figure 1 below.
This is one possible answer out of infinitely many. This is because we can change the scale factor to any nonnegative real number we want.
-------------------
Another example:
Instead of doubling the coordinates of the translation vector, let's triple them.
<4,-2> triples to <12,-6>
Then start at B'(2,9) and move right 12 and down 6 to arrive at C'(14,3) which is another possible answer out of infinitely many.
See figure 2 below.
Pick whichever of (10,5) or (14,3) is your favorite to get the final answer, assuming your teacher wants you to write one (x,y) location only. Or pick some other scale factor (other than 2 or 3) and follow the same idea to get some other possible location of point C'.
Answer:
C' = (10, 5)
Dilation by a scale factor of 2 with the origin (0, 0) as the center of dilation, followed by a translation of 1 unit up.
Step-by-step explanation:
If two triangles are said to be similar, their corresponding angles are congruent and their corresponding sides are in the same ratio.
Therefore, to maintain similarity (and thus keep the corresponding angles of both triangles the same) but not maintain congruence, dilate triangle ABC.
Given vertices of triangle ABC:
A = (0, 0)B = (1, 4)C = (5, 2)Given vertex of triangle A'B'C':
B' = (2, 9)If ΔABC is dilated by a scale factor of 2, with the origin as the center of dilation, B' = (2, 8). If the triangle is then translated 1 unit up, B' = (2, 9), which matches the given coordinate of point B'.
Therefore, the series of transformations is:
Dilation by a scale factor of 2 with the origin (0, 0) as the center of dilation.Translation of 1 unit up.Mapping Rule: (x, y) → (2x, 2y + 1)
Therefore, the coordinates of point C' are:
⇒ C' = (2(5), 2(2) + 1) = (10, 5)

It is given that there are 6 books in total, with 2 mysteries, 3 science fiction books, and 1 biography.
Recall that the probability of an event is the ratio of the number of favorable outcomes to the total number of possible outcomes.
(a) It is required to find the probability of selecting one mystery and then one science fiction, with replacement.
The probability of selecting one mystery is:
[tex]P(M)=\frac{1}{6}[/tex]The probability of selecting one science fiction next with replacement is:
[tex]P(S)=\frac{1}{6}[/tex]The probability of independent events is the product of their respective probabilities.
Hence, the probability of selecting one mystery and then one science fiction, with replacement is:
[tex]P(M)\cdot P(S)=\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36}[/tex]The answer is 1/36.(b) It is required to find the probability of selecting one mystery and then one science fiction, without replacement.
Since there is no replacement, the probability of selecting one science fiction next without replacement is:
[tex]P(S)=\frac{1}{6-1}=\frac{1}{5}[/tex]Hence, the probability of selecting one mystery and then one science fiction, without replacement is:
[tex]P(M)\cdot P(S)=\frac{1}{6}\cdot\frac{1}{5}=\frac{1}{30}[/tex]The answer is 1/30.A club consists of 15 people including Ali, Kendra,

The required probability of the random event is 0.273.
The probability is estimated by dividing the total number of possible outcomes by the number of possible ways the event could occur.The probability and chances of that happening are two distinct ideas. Odds are calculated by dividing the probability of an event by the likelihood that it won't.Keep in mind that a president, vice president, and treasurer will be chosen at random from the 15 members. The number of options to choose from to fill these spots is thus:

Answers
A company purchased a new truck, then the book value of the truck on December 31, 2019 is $51,000, because the company uses the straight-line method of depreciation.
A company purchased a new truck at a cost = $72,000 on July 1, 2019.
Estimated to have a useful life time = 5 years
A salvage value = $2,000
The formula for depreciation expense, using straight line method is;
What is a depreciation expense :Depreciation expense is the cost of an asset that has been depreciated for a single period, and shows how much of the asset's value has been used up in that year. Accumulated depreciation is the total amount of depreciation expense that has been allocated for an asset since the asset was put into use.
Based on the given conditions, formulate :
= (Cost - Salvage value) / life time (Equation-1)
We consider,
Cost = $72,000
Salvage value = $2,000
Life time = 5 years
We can substitute this values in equation-1,
So,
We can write,
= ($72,000 - $2,000) / 5
= $70,000 / 5
= $14,000.
Therefore,
The book value of the truck on December 31, 2019 would be;
= (cost - book value x (difference of year + difference of months/total months))
= $72,000 - $14,000 × (1 + 6/12)
= $72,000 - $14,000 x (1+1/2)
= $72,000 - $14,000 x (1+0.5)
= $72,000 - $14,000 x 1.5
= $72,000 - $21000
= $51,000
Note that we arrived at the value of 6 because July to December is 6 months.
Therefore,
The book value of the truck on December 31, 2019 is $51,000, because the company uses the straight-line method of depreciation.

By applying the exterior angle property, the value of x is equal to 5.
What is the exterior angle property?The exterior angle property can be defined as a theorem which states that the measure of an exterior angle in a triangle is equal in magnitude to the sum of the measures of the two remote or opposite interior angles of that triangle.
How to determine the value of x?In order to determine the value of x in triangle STU (ΔSTU), we would have to apply exterior angle property.
Mathematically, the exterior angle property can be used to model triangle STU (ΔSTU) and this is given by:
m<TUV = m<STU + m<UST
Substituting the given parameters into the formula, we have;
(7x+6)° = (3x + 14)° + (2x + 12)°
7x + 6 = 5x + 16
7x - 5x = 16 - 6
2x = 10

A fashion photographer needs to hire a stylist to prepare her models. Emmet charges $177 for showing up, plus $75 per hour. Pam charges $187 plus $70 per hour. The photographer realizes that, given the expected duration of her photo shoot, either stylist would cost her the same amount. What would the duration be? What would the cost be?
Answers
Emmet charges $177 for showing up, plus $75 per hour
Total charge = Show up charge + Per hour charges
Pam charges $187 plus $70 per hour
either stylist would cost her the same amount
i.e the total cost of photographer and stylist
Let x be the time taken in shoot
so, the charge of Emmet is 177 + 75x
The charge of palm = 187+70x
Since the charge is equal so,
[tex]\begin{gathered} 177+75x=187+70x_{} \\ 75x-70x=187-177 \\ 5x=10 \\ x=2 \end{gathered}[/tex]we get x= 2
i.e. 2 hours
The duration at which the cost of palm and emmet is equal is 2 hours
for the cost
substitute the value of x in the cost equation :
Emmet = 177 + 75x
Emmet cost=177+75(2)
Emmet cost = 327
Since the cost is same so,
The cost of emmet and palm is $327

• Distance = 380 miles
,• Time = 6 hours
,• Daily cost for meals = $20 per person
,• Cost of gas = $3.59 per gallon
,• Vehicle gets 15 miles per gallon.
Let's calculate the cost per person for this trip.
We have the following:
To find the total cost of gas they used for this trip, we have:
[tex]\frac{380}{15}*3.59=90.95[/tex]The total cost of gas for this trip is $90.95
The cost of gas per person will be:

EXPLANATION
To determine whether WX and YZ are parallel or perpendicular, wehave to find their slopes and compare them.
Slope is given as:
[tex]\text{slope = }\frac{y_2-y_1}{x_{2_{}}-x_1}[/tex]SLOPE OF WX
For WX,
(x1, y1) = (6, -6)
(x2, y2) =(7, 1)
So:
[tex]\begin{gathered} \text{slope = }\frac{1\text{ - (-6)}}{7\text{ - 6}}\text{ = }\frac{1\text{ + 6}}{1} \\ \text{slope = 7} \end{gathered}[/tex]SLOPE OF YZ
For YZ:
(x1, y1) = (3, -1)
(x2, y2) = (2, 6)
So:
[tex]\begin{gathered} \text{slope = }\frac{6\text{ - (-1)}}{2\text{ - 3}} \\ \text{slope = }\frac{6\text{ + 1}}{-1} \\ \text{slope = -7} \end{gathered}[/tex]For WX and YZ to be parallel, their slope must be the same.
For WX and YZ to be perpendicular, the slope of one must be the negative inverse of the other.
Since their slopes are neither the same or the negative inverse of one another, WX and YX are neither parallel or perpendicular to one another.
prove that the sum of the lengths of the diagonals of a quadrilateral is less than the perimeter but greater than the half of the perimeter of this quadrilateral
Answers
Let us consider a quadrilateral ABCD (as shown in the figure below) such that AC and BD are the two diagonals of ABCD.
Now, in triangle ABC and triangle ADC, by using the properties of triangle inequality we have-
AB +BC > AC .... (1)
and AD + CD >AC .... (2)
adding equations (1) and (2) we get-
AB+ BC+CD+AD > 2AC .... (3)
Similarly for diagonal BD we get-
AB+BC+CD+AD > 2BD .... (4)
Adding equations (3) and (4) we get-
2(AB+BC+CD+AD) > 2(AC+BD)
⇒ (AB+BC+CD+AD) > AC+BD
here (AB+BC+CD+AD) = perimeter of quadrilateral.
Hence, we have proven that the sum of the length of the diagonals of a quadrilateral is less than the perimeter.
Now the 2 diagonals divide the quadrilateral into 4 quadrilaterals
Therefore, AO+OD > AD
OD+OC > CD
OC+OB > BC
and OA+OB > AB
Adding all these equations-
2(AC+BD)>AB+BC+CD+AD
⇒AC+BD > 1/2(AB+BC+CD+AD)
Hence, we've proven that the sum of the length of the diagonals is greater than the half of the perimeter of this quadrilateral.

The slope of the line is 125.
The slope in the context represent the change in price with respect to the sizes of the houses.
The line won't pass through the point (5, 650)
How to find the slope of a line?The slope of a line is the change in y with respect to change in x.
Therefore,
slope = m = y₂ - y₁ / x₂ - x₁
using (0, 0)(2, 250)
m = 250 - 0 / 2 - 0
m = 250 / 2
Therefore,
m = 125
The slope simply implies the change in price with respect to the change in sizes of the houses.
Using the slope intercept equation we can know if the line passes through (5, 650).
Therefore,
y = 125x + 0
625 = 125(5)
Therefore, the line won't pass through the point (5, 650).

what number do I need to add -5 to get -7
Answers
- 5 - 2 = - 7
The number that you need to add to - 5 to get - 7 is - 2
This can be ssen on the number line. If you are adding, you move towards the right but since we are adding a negative number, the - sign makes the plus sign to become - sign. So we would subtract by moving 2 points to the left of -5 and that gives - 7
Suppose you have an experiment where you toss a fair coin 3 time you didn't count the number of heads observe over those 3 tosses use this experiment to address each of the falling question round solution to 3 destiny places
Answers
a) In order to complete the table for the probability distribution for the variable X:
X = the number of heads observed when you flip a coin three times,
b) we create a list of all the possible outcomes. We use the notation: H = heads, T = tails.
The possible outcomes after tossing the coin three times are:
[tex]HHH,HHT,HTH,THH,TTT,TTH,THT,HTT[/tex]From the list above we see that we have 8 equiprobable events. Now, we classify the events according to the number of Heads included.
- Events with x = #H = 0: TTT
- Events with x = #H = 1: HTT, THT, TTH
- Events with x = #H = 2: HHT, HTH, THH
- Events with x = #H = 3: HHH
Using the data above we compute the probabilities for each x, we simply compute the quotient between the number of outcomes of each case by N = 8 (the total number of possible outcomes):
[tex]\begin{gathered} P\mleft(x=0\mright)=\frac{1}{8}=0.125 \\ P(x=1)=\frac{3}{8}=0.375 \\ P(x=2)=\frac{3}{8}=0.375 \\ P(x=3)=\frac{1}{8}=0.125 \end{gathered}[/tex]c) Shape of the probability disribution. The probability distribution of x is: Symmetric.
d) Using the data above, we can compute the mean number of heads for the distribution:
[tex]\begin{gathered} E(x)=\sum ^3_{n=0}x_n\cdot P(x_n_{}) \\ E(x)=0\cdot P(x=0)+1\cdot P(x=1)+2\cdot P(x=2)+3\cdot P(x=3) \\ E(x)=0+1\cdot0.375+2\cdot0.375+3\cdot0.125 \\ E(x)=\frac{3}{2}=1.5 \end{gathered}[/tex]So the mean number of heads for this distribution is 1.5
A pizza parlor offers a choice of 12 different toppings. How many 2-topping pizzas are possible? (no double-orders of toppings are allowed)
Answers
==========================================================
Explanation:
There are 12 choices for the first topping and 11 for the next topping. The decrease is to account for the fact we cannot select a repeat topping.
That gives 12*11 = 132 permutations. If order of toppings mattered, then this would be our final answer.
However, the topping order doesn't matter. So we need to divide by 2 to correct for the double counting.
There are 132/2 = 66 combinations.
------------
Alternative Method:
n = 12 toppings are available and r = 2 selections are allowed
Order doesn't matter so we use the nCr combination formula
[tex]n C r = \frac{n!}{r!(n-r)!}\\\\12 C 2 = \frac{12!}{2!*(12-2)!}\\\\12 C 2 = \frac{12!}{2!*10!}\\\\12 C 2 = \frac{12*11*10!}{2!*10!}\\\\ 12 C 2 = \frac{12*11}{2!}\\\\ 12 C 2 = \frac{12*11}{2*1}\\\\ 12 C 2 = \frac{132}{2}\\\\ 12 C 2 = 66\\\\[/tex]
There are 66 combinations
Notice the 2nd to last step involves 132/2 which was mentioned in the previous section.
