Rewrite the equation in Ax+By=C form. Use integers for A,B,and C. y+5=5(x-4)

Answers

Answer 1

As per the given details, the equation in Ax + By = C form is -5x + y = -25, where A = -5, B = 1, and C = -25.

To rewrite the equation y+5=5(x-4) in Ax+By=C form, we need to simplify and rearrange the equation to isolate y on one side:

y + 5 = 5(x - 4)

y + 5 = 5x - 20 (Distribute 5 on the right side)

y = 5x - 20 - 5 (Subtract 5 from both sides)

y = 5x - 25

Now the equation is in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. To rewrite it in Ax + By = C form, we need to rearrange the terms to get the x and y terms on the left side and a constant on the right side:

y = 5x - 25

-5x + y = -25

So the equation in Ax + By = C form is -5x + y = -25, where A = -5, B = 1, and C = -25.

QUESTION SIX Solve the following problems: (a) Find the gradient, x and y intercepts of 3x + 4y + 12 = 0. Sketch the graph. (6 Marks) (b) Find the gradient, x and y intercepts of the line I, passing through the points P (-1,4) and Q (3,0). Sketch the graph. (6 Marks) (c) A line 1₂ is perpendicular to 4. Find its gradient. (2 Marks) (14 Marks)​

Answers

The sketches of the graphs are added as an attachment and the gradient of the perpendicular line l₂ is 1

Finding the gradient, x and y intercepts

Given that

3x + 4y + 12 = 0

Set x = 0 to determine the y-intercept

4y + 12 = 0

So, we have

y-intercept = -3

Set y = 0 to determine the x-intercept

3x + 12 = 0

So, we have

x-intercept = -4

For the gradient, we make y the subject in 3x + 4y + 12 = 0.

y = -3/4x - 12/4

y = -3/4x - 3

So, the gradient is -3/4

The sketch of the graph is attached.

Finding the gradient, x and y intercepts

Here, we have the points P (-1,4) and Q (3,0).

The gradient is

gradient = (0 - 4)/(3 + 1)

gradient = -1

From the point, we have

x-intercept = 3

For the y-intercept, we have

(0 - 4)/(3 + 1) = (y - 4)/(0 + 1)

(y - 4)/(0 + 1) = -1

y - 4 = -1

y-intercept = 3

So, the equation is

y = -x + 3

The sketch of the graph is attached.

Finding the gradient of l₂

We understand that l₂ is perpendicular to l

The gradients of perpendicular lines are

Answers

Answer:

a  

Step-by-step explanation:

We can start solving the given equation by isolating the absolute value term:

4|x - 3| = 0

Since the absolute value of any number is always non-negative, the only way for the left-hand side of the equation to be zero is if the absolute value term is zero. This means:

|x - 3| = 0

And the only solution to this equation is:

x - 3 = 0

x = 3

During certain time periods at a​ hospital, patients arriving at the emergency room have waiting times that are uniformly distributed between 0 and 7 minutes. Assume that a patient is randomly​ selected, and find the probability that the waiting time is less than 0.75 minutes. (Round to three decimal places)

Answers

Since the waiting times are uniformly distributed between 0 and 7 minutes, the probability density function (PDF) of the waiting time is:

f(x) = 1/7 for 0 ≤ x ≤ 7

0 otherwise

To find the probability that the waiting time is less than 0.75 minutes, we need to integrate the PDF from 0 to 0.75:

P(X < 0.75) = ∫[0,0.75] f(x) dx

P(X < 0.75) = ∫[0,0.75] 1/7 dx

P(X < 0.75) = [1/7 * x] [0,0.75]

P(X < 0.75) = 1/7 * 0.75

P(X < 0.75) = 0.1071

Therefore, the probability that the waiting time is less than 0.75 minutes is 0.1071 (rounded to three decimal places).

T/F True Logistic Regression is applied when the Dependent Variable is of Continuous nature.

Answers

It is used in various fields, such as healthcare, marketing, and social sciences.

False. Logistic regression is used when the dependent variable is binary or categorical (i.e., a nominal or ordinal variable). It is not appropriate for continuous dependent variables.

Logistic regression models the probability of an event occurring, where the event is represented by a binary variable (such as yes/no, success/failure, etc.). The output of the logistic regression model is the probability of the event occurring given the values of the independent variables. This probability can take any value between 0 and 1.

The logistic regression model assumes that the log odds of the event occurring (i.e., the logarithm of the probability of the event divided by the probability of its complement) can be modeled as a linear function of the independent variables. The coefficients of this linear function are estimated using maximum likelihood estimation.

Overall, logistic regression is a commonly used technique in statistics and data analysis for modeling the probability of a binary or categorical outcome. It is used in various fields, such as healthcare, marketing, and social sciences.

A set of data items is normally distributed with a mean of 80 and a standard deviation of 9. Convert 71 to a z-score.
271 = 0
(Type an integer or a decimal.)

Answers

The z-score for 71 is -1.

Understanding Z-score calculation

z-score is a measure of how many standard deviations an observation or data point is away from the mean of a distribution.

It is calculated by subtracting the mean from the observation and then dividing the result by the standard deviation: z = (x - μ) / σ

A positive z-score means that the data point is above the mean, while a negative z-score means that it is below the mean.

Applying the formula to solve our question

Here is a proven formula to use:

z = (x - μ) / σ

where:

x = the data item (x = 71)

μ = the mean of the distribution (μ = 80)

σ = the standard deviation of the distribution (σ = 9)

Substituting the values, we get:

z = (71 - 80) / 9

z = -1

The slope of the polar curve at θ = π/4 is 24. Therefore, option D is correct.

To find the slope of the polar curve r = 6cos(2θ) - 5 at θ = π/4, we need to find the derivative of r with respect to θ, and then substitute θ = π/4 into the resulting expression.

Using the chain rule of differentiation, we have:

dr/dθ = dr/d(cos(2θ)) * d(cos(2θ))/dθ

To find the first derivative, we can use the power rule of differentiation:

dr/d(cos(2θ)) = -12sin(2θ)

To find the second derivative, we can use the chain rule again:

d(cos(2θ))/dθ = -2sin(2θ)

Substituting these into the expression for dr/dθ, we get:

dr/dθ = -12sin(2θ) * (-2sin(2θ)) = 24sin^2(2θ)

Now, substituting θ = π/4, we get:

dr/dθ|θ=π/4 = 24sin^2(π/2) = 24

The slope of the polar curve at θ = π/4 is therefore 24.

c is y-intercept

An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

A bottle of water has a diameter of 3 inches and a height of 8 inches, and a mass of 1250 g. What is the volume and density?

Answers

The volume of the bottle is 56.52 cubic inches, and the density is 22.12 g/in³.

What is the volume and density of the bootle water?

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 ).

Density is expressed mathematically as;

p = m / v

Where m is mass and v is volume.

Given that:

Diameter = 3 in

Radius r = diameter/2 = 3/2 = 1.5 in

Height h = 8 in

Mass m = 1250 g

Find the volume:

V = π × r² × h

V = 3.14 × (1.5 in )² × 8in

V = 56.52 in³

Find the density:

p = m / v

p = 1250g / 56.52 in³

p = 22.12 g/in³

Therefore, the density is 22.12 g/in³.

Solve for x. Assume that lines which appear to be diameters are actual diameters.

Answers

Answer:

x = 9

Step-by-step explanation:

We Know

A circle is 360°

An angle is 85° & one is 130°

Find x

We Take

85° + 130° + 16x + 1 = 360°

216 + 16x = 360°

16x = 144°

x = 9

topic: upper and lower bounds
why does there need to be a 5 placed at the end of 8.23, 8.24, 3.4 and 3.5?
Context cleared up in the picture provided:​

Answers

Note that the upper bound for v is 2.356.

What is the explanation for the above figure?

To find the upper bound for v, divide te upper bound for s by the lower bound for t,    because dividing by a   smaller integer give a bigger quotient.

Adding 0.5 x 0.1 t to the value of s yields the upper bound for s with t decimal places.

As a result, the upper bound for s with two decimal places is......

8.24 + 0.5 x 0.1² = 8.245

The lower bound for t with 1   decimal place is simply the given value of 3.5.

So, the upper bound for v is  ..

v = s/t = 8.245/3.5 = 2.355714...

Rounding this to 3 decimal places, we get:

v ≈ 2.356
