Answer:

11a+12b

Step-by-step explanation:

9a+12b+2a=11a+12b

Answer:

4/5

Step-by-step explanation:

Using the Pythagorean Identity,

\( \sin {}^{2} ( \alpha ) + \cos {}^{2} ( \alpha ) = 1\)

Note that

\( \cos {}^{2} ( \alpha ) \)

is basically

\(( \cos( \alpha ) ) {}^{2} \)

So that means

\( \cos {}^{2} ( \alpha ) = ( \frac{3}{5} ) {}^{2} = \frac{9}{25} \)

So we have

\( \sin {}^{2} ( \alpha ) + \frac{9}{25} = 1\)

Solve for sin a.

\( \sin {}^{2} ( \alpha ) = \frac{25}{25} - \frac{9}{25} \)

25/25 is the same as 1.

\( \sin {}^{2} ( \alpha ) = \frac{16}{25} \)

Take the square root.

since sin is positive in the first quadrant, take the principal square root.

\( \sin( \alpha ) = \frac{ \sqrt{16} }{ \sqrt{25} } \)

\( \sin( \alpha ) = \frac{4}{5} \)

The statement "Basketball players' gender does not seem to affect shoe preference for the players in the survey" is incorrect.

Based on the data in the table, we can determine the correct or incorrect statements:

Correct – The male basketball players prefer hightop shoes.

The data shows that out of the male basketball players surveyed, 40 of them prefer hightop shoes, while only 10 prefer lowtop shoes.

Incorrect – The female basketball players prefer hightop shoes.

The data shows that out of the female basketball players surveyed, 60 of them prefer hightop shoes, while 15 prefer lowtop shoes. Therefore, more female players prefer hightop shoes, not lowtop shoes.

Incorrect – Basketball players' gender does not seem to affect shoe preference for the players in the survey.

The data clearly shows a difference in shoe preference based on gender. Among male players, a larger proportion prefers hightop shoes, while among female players, there is also a preference for hightop shoes, although not as pronounced as among males.

In summary:

The male basketball players prefer hightop shoes.

The female basketball players also show a preference for hightop shoes, but it is not as pronounced as among males.

Therefore, the statement "Basketball players' gender does not seem to affect shoe preference for the players in the survey" is incorrect.

Please note that the conclusions are based on the given data in the table and may not necessarily represent the preferences of all basketball players in general.

Answer:

\(gy78093 x^{2} 67\)

Step-by-step explanation:

Jack and Jills' speed in miles per hour is 4

The given parameters are:

Jack speed = x^2-11x-22

Jill distance = x^2-3x-54 and time = x + 6

Speed is calculated as:

Speed = Distance/time

So, we have:

Jill speed = x^2-3x-54/x + 6

Factorize the numerator

Jill speed = (x + 6)(x - 9)/x + 6

Cancel the common factor

Jill speed = x - 9

Both speeds are equal.

So, we have:

x^2-11x-22 = x - 9

Collect like terms

x^2-11x - x -22 + 9 = 0

Evaluate

x^2 - 12x - 13 = 0

Factorize the expression

(x + 1)(x - 13) = 0

Solve for x

x = -1 or x = 13

x cannot be negative.

So, we have:

x =13

Substitute x =13 in Jill speed = x - 9

Jill speed = 13 - 9

Evaluate

Jill speed = 4

Hence, their speed in miles per hour is 4

Answer:

3 = 0.25 + 0.5d

Step-by-step explanation:

Given that:

Amount charged per hour = $2

Time left before inserting $d = 15 minutes

Total time after inserting $d = 3 hours

Total time of 3 hours = time left by previous driver + hours purchased with $d

$2 = 1 hour

$d = x

2x = d

x = d/2 ; 0.5d

Since 15 minutes is left before inserting $d

15 minutes to hour ; 15/60 = 0.25

Total time of 3 hours = time left by previous driver + hours purchased with $

3 = 0.25 + 0.5d

There will be a pivot position in each row. If a row did not have a pivot position then the equation Ax = b would be inconsistent. The correct answer is C.

A matrix is a collection of numbers, encompassed by brackets.

The numbers are known as matrix elements or entries. The components are organized in rows (horizontal) or columns (vertical), which determine the matrix's size (dimension or order).

This statement C is true because, in the reduced echelon form of a matrix, the pivot position in each row indicates the non-zero leading term in that row, which corresponds to a unique unknown variable. If a row did not have a pivot position, then the corresponding equation would be equivalent to 0 = b, which is inconsistent.

Therefore, in order for Ax = b to have a unique solution, it is necessary that each row in the reduced echelon form of A has a pivot position.

Step-by-step explanation:

X 1.05 because the price is increasing by 5% and ^3 because there are three years between 2014 and 2017

Hence, three points. That can be plot on graph by using this linear equation are(0 ,0) (1 ,80) (2 , 160)

A linear equation is a two-variable equation that, when plotted on a graph, results in a straight line. Each term in the equation, which has a degree of 1, has an exponent of 1. Real-world events like the correlation between temperature and time of day are modelled using linear equations. Y = mx + b, for instance, is a linear equation where m is the line's slope and b is the y-intercept

We may use the slope-intercept form of a linear equation, which is y=mx+b where m is the slope and b is the y-intercept, to graph the equation Y=0.80x100.

In this instance, y=0.80x100 can be written as y=80x.

This line has an 80 percent slope, which means that for every increase in x of one, y rises by 80 percent.

We can select any three x values and then determine the matching y values to locate three locations on this line.

As an illustration,

if we select x=0, then y=80(0)=0

gives us the point. (0,0).

If we select x=1, then y=80(1)=80 and

we are presented with the point. (1,80).

If we select x = 2, then y = 80(2) = 160

giving us the point. (2,160).

By using the definition of the equation of the line and algebraic handling, the equation of the line that passes through the point M(x, y) is y = 3 · x + 1.

In this problem we find the case of a line equation of the form y = k · x + 1, where k is the slope of the line, that passes on the point M(x, y) = (2, 7). To find the equation, we need to need to substitute on variables x and y and clear k, before presenting the corresponding equation.

If we know that x = 2 and y = 7, then the equation of the line is:

7 = k · 2 + 1

7 = 2 · k + 1

2 · k = 6

k = 3

Thus, the equation of the line that passes through the point M(x, y) is y = 3 · x + 1.

A) x = 15

Step-by-step explanation:

4x - 30 = 2x

subtract 2x from each side of the equation:

2x - 30 = 0

add 30 to each side:

2x = 30

Step-by-step explanation:

remember that,

when a transversal crosses two parallel lines then the Alternate interior angles are equal that is being said

\( \displaystyle 4x - 30 = 2x\)

cancel 2x from both sides:

\( \displaystyle 2x - 30 = 0\)

add 30° to both sides:

The equations of the two circles are (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4 and (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

The equation of a circle with centre (a,b) and radius r is given by (x-a)^2 + (y-b)^2 = r^2.

C1 has centre (0,0) and radius 2, so its equation is (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4.

C2 touches the x and y axes each in one point, so it must have a centre on the line y=x and a radius equal to the distance from the centre to either of those points of tangency. Since the centre of C2 is on the line y=x and it is in the first quadrant, the coordinates of the centre are (1,1). The distance from the centre to the point of tangency on the x-axis is 1, so the radius is 1. The equation of C2 is (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

Therefore, The equations of the two circles are (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4 and (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

The given series, ∑(k=1 to infinity) ln(k)/k, converges. To determine whether the series converges or diverges, we can analyze it using the limit comparison test.

Let's consider the harmonic series ∑(k=1 to infinity) 1/k, which is a well-known divergent series. We can compare our given series with the harmonic series by taking the limit of the ratio of their terms as k approaches infinity.

lim(k→∞) (ln(k)/k)/(1/k) = lim(k→∞) ln(k) = ∞.

Since the limit of this ratio is infinite, it means that the given series grows faster than the harmonic series. As a result, our series also diverges. However, we need to be careful when using the limit comparison test. We should check if the terms of the series are positive, which is the case here. The positive terms and the divergence of the harmonic series confirm that our given series diverges. Therefore, the statement in the question that the series converges is incorrect. The series actually diverges.
