The slope is 4 and y- intercept is 13

A number that describes a line's direction and steepness is known as the slope or gradient of a line in mathematics.

A slope exists Numerical calculation of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment stands as the proportion of the vertical to the horizontal distance between any two points on it (“slope equals rise over run”).

Given

Slope

y = 4x-3

dy/dx = 4

slope =  4

Sphenathi and the other matriculants must travel at an average speed of approximately 107 km/h to reach Uptington by 09:45.

To determine the average speed at which Sphenathi and the other matriculants must travel to reach Uptington by 09:45, we need to calculate the time available for the journey and the distance between the two locations.

The time available is from 07:25 to 09:45, which is a total of 2 hours and 20 minutes. We need to convert this time to hours by dividing by 60:

2 hours + 20 minutes / 60 = 2.33 hours

Now, let's calculate the distance between Bloemfontein and Uptington. Suppose the distance is 'd' kilometers.

We can use the formula for average speed: average speed = distance / time

In this case, the average speed should be such that the distance divided by the time is equal to the average speed.

d / 2.33 = average speed

Now, let's assume that Sphenathi and the other matriculants must travel a distance of 250 kilometers to reach Uptington. We'll substitute this value into the equation:

250 / 2.33 = average speed

To find the average speed to the nearest km/h, we'll calculate the result:

average speed ≈ 107.3 km/h

Therefore, Sphenathi and the other matriculants must travel at an average speed of approximately 107 km/h to reach Uptington by 09:45.

Answer:

# of reserved seats = R;  # of general admission seats = G

                                                    G - R = 85

                                         $18R + $9G =$3600

Multiply 1st equation by 18:  18G - 18R = 1530

Rearrange 2nd equation:   $9G + $18R =$3600

Combine the equations:               27 G  =   5130

                                                       G  =  190

(x+7)(5x +2)

1) Let's factor the following expression 5x² +37x +14.

Checking the coefficients a =5, b= 37 and c= 14

Since a is different than 1 then we need another procedure.

2) We need to multiply a by c = 5 x 14 = 70 and look at b= 37.

Which are two numbers whose sum is 37 and their product is 70?

35 +2, and 35 x 2

Let's rewrite the whole expression, replacing it

5x² + 35x +2x +14 Instead of 37x write 35x +2x

5x² + 35x +2x +14 Group these terms

5x(x+7) +2(x+7) As we can see there's repetition so

(5x +2)(x+7)

3) Hence, the answer is 5x² +37x +14 = (5x +2)(x+7) or (x+7)(5x+2)

\(n^{5}= 1254\\n^{5} = 2.3.11.19\)

Therefore it is not possible that n is a perfect power of 5

           it is approximately 4.16

Answer:

n ≈ 4.165

Step-by-step explanation:

To solve this, you need to take the 5th root of both sides:

\(n^5=1,254\)

\(\sf{\sqrt[5]{n^5} =\sqrt[5]{1254}}\)

On the lhs we're only left with n as n^5 and the 5th root cancel each other out.

On the right-hand side we need to calculate:

\(n\approx4.165\)

Scale of the model is found to be 1 : 30 using the ratio method.

A model of a car is 4 inches long.

The actual car is 10 feet long.

 4 in. = 10 ft. ( since given )

Divide both sides by 4, we get

∴ 1 in. = 2.5 ft.

We use the ratio here to compare the lengths of the actual car and its model.

A ratio scale is a quantitative measurement scale that is used to compare numbers.

The model is 4 inches long while the actual car is 10 feet long.

One foot is equal to 12 inches. Therefore the car in terms of inches is:

10 feet × 12 inches = 120 inches

The ratio scale is the length of the model of the car : length of the actual car

= 4 : 120

= 1 : 30

Therefore the scale of the model is 1: 30.

Step-by-step explanation:

sorry if its wrong im just trying to help

Based on the scatterplot, The best prediction of the number of baseballs that will be used if 275 pitches are thrown will be 150. Option A is correct.

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

Given this information, the scatterplot below depicts the correlation between the number of baseballs used in 14 games and the number of pitches thrown in these games.

Making forecasts about the future is possible with a scatter plot. You can draw a line, referred to as a best-fit line, that is near the majority of the data points in order to aid in the forecasts. A line should be drawn with around half of the data points above and half below it.

Thus, based on the scatterplot, The best prediction of the number of baseballs that will be used if 275 pitches are thrown will be 150. Option A is correct.

Step-by-step explanation:

The statistic provided is that of the population but the statistic you seek is that of the sample.

Looking at the statistic itself, Variance is the square of Standard Deviation or standard deviation is the square root of variance.

Hence you calculate the standard deviation of the population mean:

√144 = 12

The population standard deviation of/from the mean value is 12.

It could be possible to decipher the sample mean from population mean but not sample size.

For any k ∈ (-∞, o), function f is strictly decreasing on the interval (-1, 1).

In mathematics, a function is a relationship or mapping between two sets of elements, known as the domain and the codomain, that assigns each element from the domain to a unique element in the codomain. It describes how inputs from the domain are transformed or related to corresponding outputs in the codomain.

The given function is f = \(\frac{kx}{x^2+1}\) ...(1),

Differentiate (1) w.r.t. x,

\(\dfrac{d}{dx}f = \dfrac{d}{dx}\frac{kx}{x^2+1}\)

f' = \(k\frac{1-x^2}{(x^2 + 1)^2}\)

Since f is decreasing on (-1, 1),

therefore

f' < 0 on (-1, 1),

\(k\frac{1-x^2}{(x^2 + 1)^2}\) < 0 on (-1, 1).

As \(\frac{1-x^2}{(x^2 + 1)^2}\) > 0 on (-1, 1),

k < 0 for f' < 0.

Therefore, k ∈ (-∞, o) for f to be strictly decreasing on (-1, 1).

To simplify the given product, we can use the properties of radicals. By assuming d ≥ 0 the product is \(3^{(3/2)} \times d^{(3/2)}.\)

Specifically, the product of radicals with the same index can be expressed as a single radical by multiplying their radicands.

In this case, we have:

3√d × 3√d × 3√d

We can write this as a single radical by multiplying the radicands:

\(3 \sqrt{d} \times 3\sqrt{d} \times 3\sqrt{d} = (3 \sqrt{d})^3\)

To evaluate this expression, we can use the property of exponents that states that the cube of a number is equal to that number raised to the third power.

Thus:

\((3 \sqrt{d})^3 = 3 \sqrt{d} \times 3\sqrt{d} \times 3 \sqrt{d}\)

           \(= 3^{(3/2)} \times d^{(3/2)}\)

Therefore, the simplified product is \(3^{(3/2)} \times d^{(3/2)}.\)
