Consider the line y= 3/5x-3Find the equation of the line that is parallel to this line and passes through the point (3, 4).Find the equation of the line that is perpendicular to this line and passes through the point (3, 4).

Answers

a) y = 3/5x + 11/5

b) y = -5/3x + 9

Explanation:[tex]\begin{gathered} a)\text{ }y\text{ = }\frac{3}{5}x\text{ - 3} \\ \text{compare with equation of line:} \\ y\text{ = mx + b} \\ m\text{ =slope, b = y-intercept} \\ m\text{ =slope = 3/5} \\ b\text{ = -3} \end{gathered}[/tex]

For a line to be parallel to another line. the slope of the 1st line will be equalt to the slope of the 2nd line:

slope of 1st line = 3/5

So, the slope of the 2nd line = 3/5

Given point: (3, 4) = (x, y)

To get the y-intercept of the second line, we would insert the slope and the point into the equation of line

[tex]\begin{gathered} y\text{ = mx + b} \\ 4\text{ = }\frac{3}{5}(3)\text{ + b} \\ 4\text{ = 9/5 + b} \\ 4\text{ - }\frac{\text{9}}{5}\text{ = b} \\ \frac{20-9}{5}\text{ = b} \\ b\text{ = 11/5} \end{gathered}[/tex]

The equation of line parallel to y = 3/5x - 3:

[tex]\begin{gathered} y\text{ = mx + b} \\ y\text{ = }\frac{3}{5}x\text{ + }\frac{11}{5} \end{gathered}[/tex][tex]b)\text{ line perpendicular to y = 3/5x - 3}[/tex]

For a line to be perpendicular to another line, the slope of one will be the negative reciprocal of the second line

Slope of the 1st line = 3/5

reciprocal of 3/5 = 5/3

negative reciprocal = -5/3

slope of the 2nd line (perpendicular) = -5/3

We need to get the y-intercept of the perpendicular line:

[tex]\begin{gathered} \text{given point: (3,4) = (x, y)} \\ y\text{ = mx + b} \\ m\text{ of the perpendicular = -5/3} \\ 4\text{ = }\frac{-5}{3}(3)\text{ + b} \\ 4\text{ = -5 + b} \\ 4\text{ + 5 = b} \\ b\text{ = 9} \end{gathered}[/tex]

The equation of line perpendicular to y = 3/5x - 3:

[tex]\begin{gathered} y\text{ = mx + b} \\ y\text{ = }\frac{-5}{3}x\text{ + 9} \end{gathered}[/tex]

We want to find the equation of the line given in the graph

We can see the four points on the graph where the line pass through

The points are

[tex](4,4),(2,3),(0,2),(-4,0)[/tex]

We first obtain the slope (m)

The formula for finding the slope is given as

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Using the points (0,2) and (-4,0) (indeed we can pick any two points, we will still obtain the same answer)

Here

[tex]\begin{gathered} x_1=0 \\ y_1=2 \\ x_2=-4 \\ y_2=0 \end{gathered}[/tex]

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{0-2}{-4-0} \\ m=\frac{2}{4} \\ m=\frac{1}{2} \\ m=0.5 \end{gathered}[/tex]

We can use any of the points above to find the equation

Equation of a line is given by

Answers

The equation of the line that goes through the point (5, -1) and is parallel to the given equation is; 3x + 2y = -7.

What is the equation of the line that gOES through the point given and is parallel tomthe given equation?

Recall from line geometry that parallel lines have equal slopes.

Therefore, by computing the slope of the equation given as follows; we have;

3x + 2y = 19.

By rearranging the equation in the slope-intercept form; y = mx + c; we have;

y = (-3/2)x + 19/2

Therefore, the slope of both lines is same and is; -3/2.

Therefore, By using the point slope equation of a straight line; (y - y1) = m (x - x1); we have;

(y - (-1)) = -3/2(x - 5)

2y + 2 = -3x - 5

3x + 2y = -7.

Ultimately, the required equation is; 3x + 2y = -7.

You are scuba diving at 120 feet below sea level. You begin to ascend at a rate of 4 feet per second.a. Where will you be 10 seconds after you begin your ascension? b. How long will it take to reach the surface?

Answers

The ascension can be modeled using the function:

[tex]d(t)=d_0-r\cdot t[/tex]

Where d is the number of feet below the sea level at time t (in seconds), d₀ is the initial "depth", and r is the ascension rate.

From the problem, we identify:

[tex]\begin{gathered} r=4\text{ feet per second} \\ d_0=120\text{ feet} \end{gathered}[/tex]

Then:

[tex]d(t)=120-4t[/tex]

a)

After 10 seconds, we have t = 10:

[tex]\begin{gathered} d(10)=120-4\cdot10=120-40 \\ \\ \Rightarrow d(10)=80\text{ feet} \end{gathered}[/tex]

After 10 seconds, we will be 80 feet below sea level.

b)

To find how long will it take to reach the surface, we need to solve the equation d(t) = 0.

[tex]\begin{gathered} d(t)=0 \\ 120-4t=0 \\ 4t=120 \\ \\ \therefore t=30\text{ seconds} \end{gathered}[/tex]

We will reach the surface after 30 seconds.

End Behavior Graphically

Answers

We will investigate how to determine the end behaviours of polynomial functions.

The function given to us is:

[tex]f(x)=123x^3+9x^4-786x-3x^{5^{}}-189x^2\text{ + 1260}[/tex]

Whenever we try to determine the end-behaviour of any function. We are usually looking for value of f ( x ) for the following two cases:

[tex]x\to\infty\text{ and x}\to-\infty[/tex]

The most important thing to note when dealing with end-behaviour of polynomial functions is that the behaviour is pre-dominantly governed by the highest order term of a polynomial. The rest of the terms are considered small or negligible when considering end-behaviours of polynomials.

The highest order terms in the given function can be written as:

[tex]f(x)=-3x^5[/tex]

Then the next step is to consider each case for the value of ( x ) and evaluate the value of f ( x ) respectively.

[tex]\begin{gathered} x\to\infty \\ f\text{ ( }\infty\text{ ) = -3}\cdot(\infty)^5 \\ f\text{ ( }\infty\text{ ) = -3}\cdot\infty \\ f\text{ ( }\infty\text{ ) = -}\infty \end{gathered}[/tex]

Similarly repeat the process for the second case:

[tex]\begin{gathered} x\to-\infty \\ f\text{ ( -}\infty\text{ ) = -3}\cdot(-\infty)^5 \\ f\text{ ( -}\infty\text{ ) = 3}\cdot\infty \\ f\text{ ( -}\infty\text{ ) = }\infty \end{gathered}[/tex]

Combining the result of two cases we get the following solution:

We have here a special case where the line is vertical. In this case, the line has an "infinite" slope (or it is not defined). Therefore, since the line is vertical and contains the point (10, 14), the line is given by the equation:

[tex]x=10[/tex]

The standard form of the line is given by the general equation:

[tex]Ax+By=C[/tex]

Then, we can rewrite the equation as follows:

We can see that this line contains the point (10,14):

We can see that the vertical line, x + 0y = 10 passes through the point (10, 14).

In summary, the line is given by x + 0y = 10 (A = 1, B = 0, C = 10).

concetta had a 2kg bag of flour. she used 180g of flour to make biscotti. how many kilograms of flour are left in the bag?

Answers

Answer

The amount of flour left in the bag = 1.82 kg

Explanation

Concetta had 2 kg of flour.

She uses 180 g of the flour to make biscotti.

We are then asked to calculate how much flour is left in kilograms.

Amount of flour left = (Initial Amount of flour) - (Amount of flour used)

Initial amount of flour = 2 kg

Amount of flour used = 180 g = 0.18 kg

Amount of flour left = (Initial Amount of flour) - (Amount of flour used)

Amount of flour left = 2 - 0.18 = 1.82 kg

Here (h, k) is the coordinate of the center of the circle and r is the radius of the circle.

*Second: We will replace the center of the circle and determine the radius:

*Third: We determine the radius of the circle by using the point given:

Answers

Let:

• A ,be the number of millilitres (mL) of solution A used.

,

• B ,be the number of mL of solution B used.

We know that Dale uses four times as much solution A as solution B, meaning

[tex]A=4B[/tex]

Now, we know that we will end up with 570 mL of pure alcohol in the final solution. Using the dilution of both A and B (20% means 0.2 and 15% is 0.15) we would have that:

[tex]0.2A+0.15B=570[/tex]

We would have the following system of equations:

[tex]\begin{cases}A=4B \\ 0.2A+0.15B=570\end{cases}[/tex]

Substituting equation 1 in equation 2 and solving for B :

[tex]\begin{gathered} 0.2A+0.15B=570 \\ \rightarrow0.2(4B)+0.15B=570 \\ \rightarrow0.8B+0.15B=570 \\ \rightarrow0.95B=570\rightarrow B=\frac{570}{0.95} \\ \Rightarrow B=600 \end{gathered}[/tex]

Substituting in equation 1 and solving for A:

[tex]\begin{gathered} A=4B \\ \rightarrow A=4(600) \\ \Rightarrow A=2400 \end{gathered}[/tex]

This way, we can conclude that 2400 mL of solution A and 600mL of solution B were used.
