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

The population of the town is 2500 and is decreasing at a rate of 3% per year. determine the population after 11 years
Answer:
[tex] \huge \boxed{ \boxed{1675}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:percentpercentage words problemPEMDASgiven:population:2500decreasing rate:3%to find:the population after 11 yearslet's solve:according to the question
population decreases in 1 year
[tex]2500 \times 3\% \\ 2500 \times \frac{3}{100} \\ 25 \times 3 \\ 75[/tex]
population will decrease in 11 years
75×11825so the population of the town after 11 years will be
2500-825

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].
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
- 7(4-1) = 14
- 28 - 7r = 14
- 7r = 42
r = -6
What the right answer
Answer:
−7(4−1) = −21
14-28-7r= −7r−14
14 - 7r = 42= r=−4

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%.

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

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
