Step-by-step explanation:

The amplitude is the value that the cosine is being multiplied by.

The general equation of a sinusoid is

\( a \cos(b(x + c) ) + d\)

where a is the amplitude

\( \frac{2\pi}{ |b| } \)

is the period

-c is the phase shift

d is the midline(vertical shift)

Here the amplitude is -1/2 so b is the correct answer.

Answer:

the amplitude of the function that is y= -1/2 cos x, is 1/2.

Step-by-step explanation:

The answer is yes, (x + 6) is a possible length of a rectangle with area x² + x − 30.

To determine whether (x + 6) is a possible length of a rectangle with area x^² + x − 30, we can use an area model to visualize the situation.

First, we need to find the width of the rectangle.

The area of a rectangle is given by the formula A = lw,

where A is the area, l is the length, and w is the width.

We are given that the area is x² + x − 30, so we can set this equal to lw and solve for w:

x² + x − 30 = (x + 6)w

w = (x² + x − 30)/(x + 6)

The length of a rectangle must be greater than or equal to its width, so we need to check whether (x + 6) is greater than or equal to (x² + x − 30)/(x + 6). This simplifies to:

(x + 6) ≥ x² + x − 30

Expanding the left side and simplifying, we get:

x² + 12x + 36 ≥ x² + x − 30

11x ≥ -66

x ≥ -6

Since x must be a positive number (since we are dealing with lengths), we can conclude that (x + 6) is the possible length of the rectangle. Therefore, the answer is yes, (x + 6) is a possible length of a rectangle with an area x² + x − 30.

The line that is tangent to both parabolas at this point will have the slope 2x = 2 * 0 = 0 and y-intercept equal to 0, giving us the equation y = 0.

To graph the two parabolas y = x^2 and y = -x^2 + 2x - 5 in the same coordinate plane, we can use a tool such as a graphing calculator or plot the points of the parabolas by hand. The first parabola, y = x^2, will be a downward-facing parabola centered at the origin with a vertex at (0,0), while the second parabola, y = -x^2 + 2x - 5, will be an upward-facing parabola that is shifted to the right by 1 unit and downward by 5 units.

Next, we want to find the lines that are simultaneously tangent to both parabolas. To do this, we find the derivative of each parabolic function, which gives us the slope of the tangent line at any point on the graph.

For the first parabola, y = x^2, the derivative is 2x, so the slope of the tangent line at any point (x, x^2) is 2x.

For the second parabola, y = -x^2 + 2x - 5, the derivative is 2x - 2, so the slope of the tangent line at any point (x, -x^2 + 2x - 5) is 2x - 2.

To find the equations of the two lines simultaneously tangent to both parabolas, we set the slopes equal to each other and solve for x. This gives us the x-coordinate of the points of tangency on both parabolas, and from there we can use the original functions to find the y-coordinate.

For example, setting the slopes equal to each other, we get:

2x = 2x - 2

0 = -2

So, x = 0, and this point (0, 0) lies on both parabolas. Therefore, the line that is tangent to both parabolas at this point will have the slope 2x = 2 * 0 = 0 and y-intercept equal to 0, giving us the equation y = 0.

We can repeat this process to find the equation of the second tangent line.

Note: There may be other points of tangency that are not shown on the graph, and these can be found using the same process.

Therefore, the line that is tangent to both parabolas at this point will have the slope 2x = 2 * 0 = 0 and y-intercept equal to 0, giving us the equation y = 0.

Answer:

x=1 and y=7

Step-by-step explanation:

7x−2y=−7;y=7

Rewrite equations:

y=7;7x−2y=−7

Step: Solve y = 7 for y:

y=7

Steps: Substitute 7 for y in 7x−2y=−7:

7x−2y=−7

7x+(−2)(7)=−7

7x−14=−7 (Simplify both sides of the equation)

7x−14+14=−7+14 (Add 14 to both sides)

7x=7

7x/7 = 7/7 (Divide both sides by 7)

x = 1

So the answer is, x=1 and y=7

To calculate the receivable days, divide the trade receivables (RM63,000) by the average daily sales (RM1,400) to get approximately 45 days.



To calculate the receivable days, we need to determine the average daily sales and then divide the trade receivables by that figure.

First, we calculate the average daily sales by dividing the total sales by the number of days in the year:

Average daily sales = Total sales / Number of days

Since the year ended on 30th June 2019, there are 365 days in total.

Average daily sales = RM511,000 / 365 = RM1,400

Next, we divide the trade receivables by the average daily sales to find the receivable days:

Receivable days = Trade receivables / Average daily sales

Receivable days = RM63,000 / RM1,400 ≈ 45 days

Therefore, Alice's receivable days on 30th June 2019 is approximately 45 days.

Answer:

Step-by-step explanation:

First of all, I have a strong feeling that that is supposed to be

\(log_2(32)=y\) so I'm going to go with that. We can solve for y by rewriting that in exponential form. Exponential form and log form are inverses of each other. If the log form of an equation is

\(log_b(x)=y\), the exponential form of it is

\(b^y=x\). We will apply that here to solve for y:

\(2^y=32\)

which is asking us, "2 to the power of what equals 32?". We can use our calculator to raise 2 to consecutive powers til we reach the one that gives us a 32, or we could solve it by writing the 32 in terms of a 2:

\(2^y=2^5\)

Since both bases are the same, 2, then the exponents are equal to one another. y = 5. This is an important rule to remember while solving either log or exponential equations.

The first five terms defined by ak are:

a0 = 4

a1 = 7

a2 = 10

a3 = 13

a4 = 16

The first five terms defined by bk are:

b0 = 5

b1 = 8

b2 = 13

b3 = 20

b4 = 29

Among the first five terms of these two sequences, only the first term, a0, and the second term, a1, are identical. So Yes, only the first two terms in both sequences are identical.

We can calculate the terms of the sequences by substituting the given values of k into the expressions for ak and bk. By evaluating the expressions for the first five values of k, we obtain the corresponding terms for each sequence.

Upon comparing the terms of the two sequences, we observe that only the first two terms, a0 and a1, are the same. The remaining terms, starting from the third term onward, differ between the sequences. Therefore, the first five terms of these two sequences have only the first two common terms .

given that for all numbers of p and q,

q = 5/3p + 46

lets find p when q is 21

so lets substitute the value of q into the given equation

q = 5/3p + 46

21 = 5/3p + 46

lets collect like terms

21 - 46 = 5/3p

-25 = 5/3p

lets cross multiply

3 X -25 = 5p

-75 = 5p

5p = -75

divide both sides by 5

5p/5 = -75/5

p = -15

therefore for all values of p and q, q = 5/3p + 46,

the value of p is -15 when q is 21

Using the logarithm of the y values will enable you to model the data better than using the square root of the y values.

The following would be the best reason to prefer the least-squares regression line that uses x to predict log(y) out of the two least-squares regression lines calculated :

Transformation of variables is an excellent method of estimating regression lines.

In a case where a scatter plot of y versus x shows a positive non-linear association, the two transformation methods that can be attempted to linearize the association are using the logarithm of the y values and using the square root of the y values.

After the two transformations have been tried, two least-squares regression lines are calculated, one that uses x to predict log(y) and the other that uses x to predict y.

Therefore, the best reason to prefer the least-squares regression line that uses x to predict log(y) is that it would work effectively in linearizing the relationship between the variables.

Furthermore, in most cases, the regression line calculated using x to predict log(y) produces better results than the regression line calculated using x to predict y.

This is because it is easier to transform the y-values logarithmically to linearize them.

Additionally, logarithmic transformation can be used to model the growth of population and bacteria since their growth is approximately logarithmic.

We conclude that there is zero (0) fraction of coal left in the bag with Tom.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole.

A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

The number is represented mathematically as a quotient, where the numerator and denominator are split.

Both are integers in a simple fraction.

A fraction appears in the numerator or denominator of a complex fraction.

The numerator of a proper fraction is less than the denominator.

So, a fraction of coal left in the bag:

To find an expression for the width of the rectangle, we can use the formula for the area of a rectangle, which is:

Area = length x width

In this case, we know that the area is given by the expression +7x² + 11x + 2 and the length is given by the expression (x + 2). So we can substitute these values into the formula and solve for the width:

+7x² + 11x + 2 = (x + 2) x width

Expanding the right-hand side, we get:

+7x² + 11x + 2 = xwidth + 2width

Rearranging terms, we get:

+7x² + 11x + 2 - xwidth - 2width = 0

Factoring out the width, we get:

width*(x - 2) + 2*(x - 1) = 0

Dividing both sides by (x - 2), we get:

width = -2*(x - 1)/(x - 2)

Therefore, an expression for the width of the rectangle is:

width = -2*(x - 1)/(x - 2)
