Find the equation of the line with slope = -5 and passing through (4,-17). write your equation in the form y = m x + b y=mx+b.

Final answer:

To evaluate the given integral, split the function at x = 3 and integrate separately. The integral evaluates to 18, which makes the correct answer 18.

Explanation:

The function we're integrating is 1, which makes this the same integral as the one in example 3 on p. 178. To evaluate this integral, we need to split it at x = 3 and integrate the corresponding functions separately.

For x ≤ 3, the function is f(x) = 3. So, the integral from 0 to 3 of 3 dx equals 9.

For x > 3, the function is f(x) = 6 - x. Integrate this from 3 to 6: ∫(6 - x) dx = 6x - 0.5x^2. Evaluating this from 3 to 6 gives 9.

[tex]10^5 * 10^6 = 10^{5+6} = 10^{11}[/tex]

Step-by-step explanation:

find the product of 100,000 and 1,000,000 using scientific notation

All whole numbers have a decimal point at the end

convert each number into scientific notation. To get scientific notation move the decimal point after 1

100000.  -----> 1.00000 ----> 1* 10^5 ----> 10^5

1000000.  -----> 1.000000 ----> 1* 10^6 ----> 10^6

a^m * a^n = a^m+n

[tex]10^5 * 10^6 = 10^{5+6} = 10^{11}[/tex]

An algebraic description of the transformation that translates a point (x, y) nine units to the right and five units down is written as the new point (x + 9, y - 5).

The algebraic description of a transformation that translates a point (x, y) nine units to the right and five units down can be written as the following ordered pair: (x + 9, y - 5).

In this transformation, the x-coordinate of each point is increased by 9 units, reflecting a horizontal translation to the right, and the y-coordinate is decreased by 5 units, representing a vertical translation downwards. Thus, if you have a point (x, y), after the transformation, it becomes (x + 9, y - 5).

For example, if your initial point is (3, 4), after the transformation it would be at (3 + 9, 4 - 5) = (12, -1).

The dimensions of the swimming pool are 51 feet (length) and 12 feet (width), determined by setting up equations based on the given information (perimeter and difference between the sides) and solving these equations using substitution.

The problem at hand is a classic algebraic word problem. It involves determining the length (x) and width (y) of a swimming pool given the perimeter and the difference between the length and width. The formulas we'll use are for the perimeter of a rectangle (2x + 2y = perimeter) and a given equation based on the description (x - y = difference).

So the dimensions of the swimming pool are 51 feet (length) and 12 feet (width).

ANSWER

We need to rewrite [tex]x+2y=6[/tex], in slope intercept form.

[tex]\Rightarrow 2y=-x+6[/tex],

[tex]\Rightarrow y=-\frac{1}{2}x+3[/tex]

The given equation has a slope of [tex]-\frac{1}{2}[/tex].

ANSWER TO QUESTION 1

We now the write given options also in slope intercept form.

For the first one, we have

[tex]y=-\frac{1}{2}x+5[/tex]

This first equation also has a slope  of [tex]-\frac{1}{2}[/tex].

Hence [tex]y=-\frac{1}{2}x+5[/tex] is parallel to [tex]x+2y=6[/tex].

ANSWER TO QUESTION 2:

The second equation is;

[tex]-2x+y=-4[/tex].

We need to write this one too in slope intercept form.

[tex]y=2x-4[/tex]

This second equation has a slope of 2

Since [tex]2\times -\frac{1}{2}=-1[/tex], the line [tex]-2x+y=-4[/tex]

is perpendicular to [tex]x+2y=6[/tex].

ANSWER TO QUESTION 3

We rewrite the equation [tex]-x+2y=2[/tex] in slope intercept form.

[tex]\Rightarrow 2y=x+2[/tex]

[tex]\Rightarrow y=\frac{1}{2}x+1[/tex]

This equation also has a slope of [tex]\frac{1}{2}[\tex]

since the slope of [tex]-x+2y=2[/tex] is not equal to the slope of [tex]x+2y=6[/tex], and the product of these two slopes [tex]\frac{1}{2} \times - \frac{1}{2} \ne -1[/tex], the two lines are neither parallel nor perpendicular.

QUESTION 4

The given line has equation [tex]x+2y=-2[/tex]. We rewrite this equation in the slope intercept form.

[tex]\Rightarrow 2y=-x-2[/tex]

[tex]\Rightarrow y=-\frac{1}{2}x-1[/tex]

This line has a slope of [tex]-\frac{1}{2}[/tex].

Since this slope is the same as the slope of the given line,

[tex]y=-\frac{1}{2}x-1[/tex] is parallel to  [tex]x+2y=6[/tex].

Dublin is 3 hours ahead of Moscow.

The difference between how time is measured in different ways; the length of a period of time. the time difference between two or more distinct time zones in terms of clock time.

Given Dublin time = 11:30 am

Moscow  time = 2:30

we can military time and subtract.

11:30 a.m. = 11:30

2:30 p.m. = 2:30 + 12:00 = 14:30

14:30 - 11:30 = 3:00

The standard form of the equation of the parabola with focus at (1, 1) and directrix 'y = 7' is (x - 1)² = 12(y - 4). The vertex is found by determining the midpoint between the focus and directrix, and the 'a' value is found by calculating half the distance between the focus and directrix.

To find the standard form of a parabola given the focus and directrix, we'll use the definition of a parabola itself. A parabola is defined as the set of points that are equidistant from a point, known as the focus, and a line, known as the directrix.

The equation representing a parabola is: (x - h)² = 4a(y - k) where (h, k) is the vertex of the parabola and 'a' denotes the distance between the vertex and the focus or the vertex and the directrix.

The mid-point of the focus (1, 1) and the directrix y=7 gives the coordinates of the vertex. So, h = 1 and k = (1+7)/2 = 4.

Now, 'a' is half the distance between the focus and directrix, a = (7-1)/2 = 3.

So, the standard form of the equation is (x - 1)² = 12(y - 4)

Answer: C. The amount earned is a function of the number of hours worked.

Explanation:

Since, a function is always the type of y= f(x), where x is independent variable and y is dependent variable which is dependent on the value of x.

Here,  a graph of Olivia's earning per hour is given.

Since, it is the obvious thing that the earning will depend on hours she works.

Thus, we can say that earning is dependent variable while hours is independent variable.

Therefore, earning makes the y-axis and number of hours makes the x-axis.

So, option C is correct.

The interval of x-values over which the function is increasing is (-3 , -1), the correct option is B.

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain.

The x values and the corresponding function values are shown in the figure.

The x and y values are:

-6      -34

-5       3

-4      -10

-3      -11

-2      -6

-1        -1

0        -2

1        -15

The  interval of x-values over which the function is increasing has to be determined.

The first option is (-6, -3) , the function is not increasing in this interval.

The second option is (-3 , -1) , the function is increasing in this interval.

The third option is(–3, 0), the function is not increasing in this interval.

The fourth option is (–6, –5), the function is not increasing in this interval.

Answer:

Option C. y = 110°

Step-by-step explanation:

In this question BD and XY are two parallel line and a transverse is intersecting both the lines at A and E.

Now ∠BAE = ∠AEY = 70° [ alternate interior angles ]

and ∠EAD + ∠BAE = 180° [ supplementary angles ]

or y + 70° = 180°

⇒ y + 70 - 70 = 180 - 70

⇒ y = 110°

To make a profit of at least $600, the number of bookends that need to be sold is calculated by adding the desired profit to the initial cost, and then dividing this sum by the net revenue per bookend. The result is approximately 144 bookends.

The subject of this problem is Mathematics, specifically a topic within business math called 'breakeven analysis' or 'cost-volume-profit analysis'. It involves calculating the point at which revenue from selling a product equals the costs associated with producing and selling that product. In this case, you have spent $154 to make wooden bookends, and you plan on selling them online for $8.50 each. Additionally, there's a $3.25 fee per bookend for wrapping and shipping, which you charge to your customers. Your goal is to make a profit of at least $600.

To calculate the number of bookends that need to be sold, we first find the net revenue per bookend. This is the selling price minus the shipping cost, which comes out to $8.50 - $3.25 = $5.25 per bookend. The desired profit is added to the cost of making the bookends to find the total required revenue, which is $600 + $154 = $754.

Finally, total required revenue is divided by the net revenue per bookend to find the number of bookends that need to be sold: $754 ÷ $5.25 = approximately 144 bookends (rounded up to the nearest whole bookend since we can't sell a fraction of a bookend). So, in order for your profit to be at least $600, you must sell at least 144 bookends.
