Find the coordinated points which quadrasects the line segments joining the points A(-3,6) and B (4,-2)
Answer:
The coordinated points which quadrasects the line segments joining the points A and B are [tex]\left(-\frac{5}{4},4\right)[/tex], [tex]\left(\frac{1}{2}, 2 \right)[/tex] and [tex]\left(\frac{9}{4},0 \right)[/tex].
Step-by-step explanation:
Let [tex]A(x,y) =(-3,6)[/tex] and [tex]B(x,y) = (4,-2)[/tex], when the line segment is quadrasected, it means that segment is divided into four equal parts. The locations are determined by the following expressions:
[tex]\vec R_{1} = \vec A + \frac{1}{4}\cdot \overrightarrow{AB}[/tex] (1)
[tex]\vec R_{2} = \vec A + \frac{1}{2}\cdot \overrightarrow{AB}[/tex] (2)
[tex]\vec R_{3} = \vec A + \frac{3}{4}\cdot \overrightarrow{AB}[/tex] (3)
Where:
[tex]\overrightarrow{AB} = B(x,y)-A(x,y)[/tex]
[tex]\overrightarrow{AB} = (4,-2) - (-3,6)[/tex]
[tex]\overrightarrow{AB} = (7,-8)[/tex]
The coordinated points which quadrasects the line segments joining the points A and B are, respectively:
[tex]\vec R_{1} = (-3,6)+\frac{1}{4} \cdot (7,-8)[/tex]
[tex]\vec R_{1} = \left(-\frac{5}{4},4\right)[/tex]
[tex]\vec R_{2} = (-3,6)+\frac{1}{2} \cdot (7,-8)[/tex]
[tex]\vec R_{2} = \left(\frac{1}{2},2 \right)[/tex]
[tex]\vec R_{3} = (-3,6)+\frac{3}{4} \cdot (7,-8)[/tex]
[tex]\vec R_{3} = \left(\frac{9}{4},0\right)[/tex]
The coordinated points which quadrasects the line segments joining the points A and B are [tex]\left(-\frac{5}{4},4\right)[/tex], [tex]\left(\frac{1}{2}, 2 \right)[/tex] and [tex]\left(\frac{9}{4},0 \right)[/tex].

17, 12, 7, 2, ...
an=
Answer:
An equation for the nth term of the arithmetic sequence 17, 12, 7, 2 is 17-5n.
Step-by-step explanation:
Given,
first term(a)=17
common difference (d)=t2-t1
=12-17
=-5
nth term of the arithmetic sequence = a+n×d
=17+n×-5
=17-5n

Work out the value of x.
Answer:
x = 69 degrees
Step-by-step explanation:
x = 360 - 168 - 123
x = 69 degrees
Answer:
x = 69
168 + 123 + x = 360 (Sum of angle at a point)
291 + x = 360
x = 360 - 291
x = 69

A warehouse buys televisions for a cost price of $640 each.
The warehouse then sells the televisions for $960 each.
Find the profit on each television as a percentage of its cost price.
choose one:
66 2/10%
50%
40%
33 1/3%
20%
The profit on each television as a percentage of its cost price is 50%.
Given that,
The cost price of the television should be $640 each.The sale price of the television should be $960 each.Now the profit percentage on each television of the cost price is:
[tex]= \frac{Sale\ price - cost\ price}{Cost\ price} \\\\= \frac{\$960 - \$640}{\$640}\\\\= \frac{\$320}{\$640}[/tex]
= 50%
Therefore we can conclude that the profit on each television as a percentage of its cost price is 50%.

Figure D'EFG' is a dilation with center (0,0) of figure DEFG. What is the scale factor? Enter your answer in the box.
ILL GIVE BRAINLIST BUT PPLEASE HELP
Step-by-step explanation:
To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:
15/6 = 2.5
So your scale factor would be 2.5
And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)

At a dock on the east coast, low tide occurs at 3 pm wi th a water depth of 5 ft. The depth at high tide is 83 ft. High tide occurs every 6 hours. Explain how to find the sinusoidal function that models the depth in terms of time, x.
Answer:
The sinusoidal function that model the depth in terms of time, 'x', is presented here as follows;
f(x) = 39·sin((π/3)·x - π) + 5
Step-by-step explanation:
A sinusoidal function is given by the general function as follows;
y = A·sin(B·x + C) + D
Where;
A = The amplitude = ([tex]y_{max}[/tex] - [tex]y_{min}[/tex])/2 = (The high tide - The low tide)/2 = (83 ft. - 5 ft.)/2 = 39 ft.
The period, T = 2·π/b = 6 hours
∴ B = 2·π/T = 2·π/6 = π/3
D = The vertical shift = The low tide = 5 ft.
The horizontal phase shift, 'C', is given as follows;
3 hrs = -C/B = -C/(π/(3 hr))
C = 3 hrs × -(π/(3 hr)) = -π
∴ C = -π
y = 39·sin((π/3)·x - π) + 5
The sinusoidal function that model the depth in terms of time, 'x', is therefore given as follows;
f(x) = 39·sin((π/3)·x - π) + 5

the mean temperature for the first 4 days in January was - 4 degrees the mean temperature for the first 5 days in January was - 6
degrees what was the temperature on the 5th day
Answer: The temperature on the 5th day is -14 degrees.
Step-by-step explanation:
If we have a set of N values:
{x₁, x₂, x₃, ..., xₙ}
The mean value of this set is:
M = (x₁ + x₂ + ... + xₙ)/N
Now, we know that the mean temperature for the first 4 days of January is -4°
Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}
We have:
M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°
Where we can replace (T₁ + T₂ + T₃ + T₄) by K
Then:
K/4 = -4°
K = -4°*4 = -16°
Is the sum of the temperatures for the first four days.
Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:
M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5
And we know that:
(T₁ + T₂ + T₃ + T₄) = K = -16°
We can replace that in the above equation to get:
M₅ = (-16° + T₅)/5 = -6°
Now we can solve this for T₅
(-16° + T₅) = 5*(-6°) = -30°
T₅ = -30° + 16° = -14°
T₅ = -14°
The temperature on the 5th day is -14 degrees.
what is 2.4 rounded to the nearest tenth
Answer:
2
Step-by-step explanation:
If the tenth place has a number under 5, round down. (2)
If the tenth place is 5 or more, roundup. (3)
The solution for the number 2.42 rounded to the nearest tenth is 2.4
Used the concept of rounding numbers which states that,
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest tenth,
The number to round is 2.42
Clearly, the number 2 placed in the hundredth place is less than 5, so round the number down.
That is 2.42 ≈ 2.4
Therefore, the solution is 2.4
