Answer:
(1/2)x + $5 (Answer A)
Step-by-step explanation:
Two points on the line representing the cost are (8, $9) and (12, $11).
The change in x is 4 (minutes); this is the 'run.' The change in y is $2 (this is the 'rise'). Thus, the slope of this line is m = rise / run = $2/(4 min), or 1/2 dollar per min.
Applying the slope-intercept formula y = mx + b, we get:
$9 = (1/2)(8) + b, and from this we see that b must be $5.
Then the correct equation is y = (1/2)x + $5.

160 m of fencing to enclose a quadrilateral shape pen (3 sided) for a children's play area. Determine the shape of the children's play area that gives the maximum area.
Answer:
A square of side length 40 m will give the maximum area of the play area
Step-by-step explanation:
Mathematically, it has been established that a square gives the maximum area of a quadrilateral
Hence, for us to have a maximum area of the given perimeter, we have to divide the perimeter by 4 to get the side length of the square
From what we have, we know that the perimeter of the fencing is 160 m
To get the side length, we divide the perimeter by 4
Side length of the shape would be 160/4 = 40 m

60°
E
D
y cm
Answer:
x = 72 degrees
y = 9.125 cm
Step-by-step explanation:
the sum of degrees of all angles in a triangle is 180.
because the triangles are similar, all the angles must be the same in both. and the side lengths of one triangle must all have the same scaling factor compared to the other triangle.
the similarity tends is that the angle at E is the same as at B (48 degrees). so, then the angles at C are 60 degrees. that leaves for the angle at D (x) 180 - 60 - 48 = 72
BC (8) is scaled to CE (10) by the factor 10/8 = 5/4
so, y must have the same scaling factor in relation to AB (7.3)
y = 7.3 × 5/4 = 9.125

Answer: 12 km\h north
Step-by-step explanation:
I actually have good guesses
Velocity = 12 km/h
-
Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:
Velocity = Distance / Time
With the above information in mind, we can calculate the velocity of the bicycle:
Velocity = 18 km / 1.5 h
Velocity = 12 km/h
Thus the velocity of the bicycle is 12 kilometers per hour.

find the mean,median and mode for x,2x,3x,4x,5x
Answer:
Mean: 3x
Median: 3x
Mode: None
Step-by-step explanation:
The mean is the sum of all the numbers divided by how many there are.
x + 2x + 3x + 4x + 5x = 15x and 15x/5 = 3x. So the mean is 3x.
The median is the number in the middle when the values are in order from least to greatest. The median is 3x.
The mode is the number that appears most often in the data set. In this case, the mode is none because no number appears more than the other numbers.

What does it mean to use the cosine value of an inverse of tan θ?
I attached the question I'm just confused.
Will it be 60°?
Answer:
[tex] \boxed{ \begin{array}{ccc} \displaystyle \theta = {120}^{ \circ} \\ \displaystyle\sin( {120}^{ \circ} ) = \frac{ \sqrt{3} }{2} \end{array}}[/tex]
Step-by-step explanation:
we are given a inverse trig
we want to figure out the value of [tex]\theta[/tex]
in that case we can consider using unit circle in unit circle the value of arctan (-√3)=120°
therefore,
the value of theta is 120°
likewise by unit circle the value of sine is

Samuel spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -14.7°F. Between 9am and noon, the temperature increased by 17.8°F. Between noon and 3pm, the temperature increased by 5.1°F. Between 3pm and 6pm, the temperature went down 14.5°F. What was the temperature at 6pm?
Answer:
The temperature at 9 am = -14.7°F
Between 9am and 12 pm = -14.7 + 17.8 = 3.1°F
Between 12pm and 3 pm = 3.1+5.1 = 8.2°
Between 3pm and 6 pm = 8.2-14.5 = -6.3°F
What is the area of a regular hexagon with sides that measure 10 feet and an
apothem that measures 8.66 feet?
Answer:
259.8 square feet
Step-by-step explanation:
What is the area of a regular hexagon with sides that measure 10 feet and an
apothem that measures 8.66 feet?
The formula to solve the above question is given as:
Area = (3√3 s²)/ 2 where
s is the length of a side of the regular hexagon
Area of this Hexagon is calculated as:
= (3√3 × 10²)/2
= 3√3 × 100/2
= 259.80762114 square feet
Approximately = 259.8 square feet
The area of the regular hexagon = 259.8 square feet

The measurement of angle P in the diagram given in the question is 61.93 °
Trigonometric ratiosThe trigonometric ratios which has been proven as regarding right angle triangles are given below:
Sine θ = Opposite / Hypothenus
Cos θ = Adjacent / Hypothenus
Tan θ = Opposite / Adjacent
With above information in mind, we can easily determine the value of angle P in the question. This is illustrated below:
How to determine the value of angle PFrom the question given above, the following data were obtained:
Hypothenus = 17 cmOpposite = 15 cmAdjacent = 8 cmAngle P =?Sine θ = Opposite / Hypothenus
Sine P = 15 / 17
Sine P = 0.8824
Take the inverse of sine
P = Sine⁻¹ 0.8824
P = 61.93 °
Thus, the value of angle P in the diagram is 61.93 °

Find the break - even points for company X, which sells all it produces, if the variable cost per unit is $3, fixed costs are $2 and YT R = 5√q, where q is the number of thousands of units of output produced.
Given:
The variable cost per unit is $3, fixed costs are $2.
The revenue function is:
[tex]Y_{TR}=5\sqrt{q}[/tex]
where q is the number of thousands of units of output produced.
To find:
The break - even points for company X.
Solution:
The variable cost per unit is $3, fixed costs are $2.
So, the cost function is:
Total cost = Fixed cost + Variable cost × Quantity
[tex]Y_{TC}=2+3q[/tex]
The revenue function is:
[tex]Y_{TR}=5\sqrt{q}[/tex]
At break - even points the profit is zero. It means the cost and revenue are equal.
[tex]Y_{TC}=Y_{TR}[/tex]
[tex]2+3q=5\sqrt{q}[/tex]
Squaring both sides, we get
[tex](2+3q)^2=(5\sqrt{q})^2[/tex]
[tex]2^2+2(2)(3q)+(3q)^2=25q[/tex]
[tex]4+12q+9q^2-25q=0[/tex]
[tex]4-13q+9q^2=0[/tex]
Splitting the middle term, we get
[tex]4-4q-9q+9q^2=0[/tex]
[tex]4(1-q)-9q(1+q)=0[/tex]
[tex](4-9q)(1-q)=0[/tex]
Using zero product property, we get
[tex]4-9q=0[/tex] and [tex]1-q=0[/tex]
[tex]q=\dfrac{4}{9}[/tex] and [tex]q=1[/tex]
[tex]q\approx 0.444[/tex] and [tex]q=1[/tex]
Therefore, the break even points are 0.444 and 1.
