Answer:

2a * 5b

Step-by-step explanation:

2 times a = 2a

5 times b = 5b

The phrase "the product" shows the 2 elements are being multiplied together.

The equation of a line that passes through the point (27, 2) and is perpendicular to the line -9x + 2y = 0 can be found using the properties of perpendicular lines. The equation is  -9x + 2y = 0 is y - 2 = (-2/9)x + 6.

To obtain the equation, we need to determine the slope of the given line and then find the negative reciprocal of that slope. The negative reciprocal of a slope is a property of perpendicular lines. Once we have the new slope, we can substitute it into the point-slope form of a linear equation.The given line has the equation -9x + 2y = 0. To find its slope, we can rearrange the equation in the slope-intercept form (y = mx + b), where m represents the slope. By isolating y, we have 2y = 9x, which simplifies to y = (9/2)x. Comparing this equation with y = mx + b, we can see that the slope of the given line is m = 9/2.

To find the negative reciprocal of this slope, we take the reciprocal of 9/2 (which is 2/9) and then negate it (change the sign). Therefore, the slope of the perpendicular line is -2/9.Now that we have the slope (-2/9) and the point (27, 2), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1). Plugging in the values, we get y - 2 = (-2/9)(x - 27). Simplifying this equation gives us the final result: y - 2 = (-2/9)x + 6.

The equation of the line that passes through the point (27, 2) and is perpendicular to the line -9x + 2y = 0 is y - 2 = (-2/9)x + 6. This equation was obtained by finding the negative reciprocal of the slope of the given line and using point-slope form of a linear equation.

From the question, we have the following parameters that can be used in our computation:

a) y = (x + 1)(5x² + 7x + 1)

b). y = (7x + 1) (2x - 4)

The roots of the polynomial functions are calculated by setting the functions to 0

So, we have

(x + 1)(5x² + 7x + 1) = 0

(7x + 1) (2x - 4) = 0

Using the zero product property, we have

x + 1 = 0 or 5x² + 7x + 1 = 0 and

7x + 1 = 0 or 2x - 4 = 0

The biggest decrease in waiting time between two consecutive eruptions is 18 minutes.

Here, we have,

To assign the biggest decrease to the biggest decrease in waiting time between two consecutive eruptions, we need to compare the decreases in waiting time for each pair of consecutive eruptions and identify the pair with the largest decrease.

Let's consider a sequence of eruption waiting times as an example:

Eruption 1: 60 minutes

Eruption 2: 70 minutes

Eruption 3: 74 minutes

Eruption 4: 62 minutes

Eruption 5: 80 minutes

To find the biggest decrease in waiting time, we compare the differences between consecutive eruptions:

Decrease between Eruption 1 and Eruption 2: 70 - 60 = 10 minutes

Decrease between Eruption 2 and Eruption 3: 74 - 70 = 4 minutes

Decrease between Eruption 3 and Eruption 4: 62 - 74 = -12 minutes

Decrease between Eruption 4 and Eruption 5: 80 - 62 = 18 minutes

From the calculations, we can see that the biggest decrease in waiting time occurs between Eruption 4 and Eruption 5, with a decrease of 18 minutes.

Therefore, the biggest decrease in waiting time between two consecutive eruptions is 18 minutes.

In order to assign the biggest decrease to the biggest decrease in waiting time between consecutive eruptions, calculate the difference in waiting times for each pair of eruptions, and the biggest decrease will be the largest difference you find.

To assign the biggest decrease to the biggest decrease in waiting time between two consecutive eruptions, you need to first identify the waiting times between each pair of consecutive eruptions. Then, calculate the difference in waiting times between each pair. For example, if the third eruption occurred after 74 minutes and the fourth after 62 minutes, the decrease in waiting time was 74 - 62 = 12 minutes. You repeat this process for all pairs of consecutive eruptions, and the biggest decrease in waiting time will be the largest difference you calculate.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Here we have the mixed numbers 1 5/8 and 9/10 and must sum them up to find the total number of miles Henry ran.

The LCD is 40:  Note that 40 is evenly divisible by both 8 and 10.

We convert 1 5/8 into the improper fraction 13/8.

Then we rewrite 13/8 as 65/40 and 9/10 as 36/40; now both quantities have the denominator 40.

Adding 65/40 and 36/40 yields 101/40 miles total, or 2.525 miles.

Answer:

160 liters

Step-by-step explanation:

"a confectioner mixes forty liters of 60%":

Equation: 40 * .60

ow plug it in

0.60*40 + 0.10x = 0.20(40+x)

"how much of the 10% syrup should she use?":

.10x

"...to make a 20% sugar syrup.":

0.20(40+x)

Now that I have split the question into equations, let's put them together:

0.60*40 + 0.10x = 0.20(40+x)

Solve:

60*40 + 10x = 20*40 + 20x

10x = 40*40

x = 160 liters (amt of 10% solution needed)

Hope this helps :)

160 liters of 10% syrup is needed to make the mixture.

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the amount of 10% syrup. Hence:

(60% of 40) + (x of 10%) = (x + 40) of 20%

0.6 * 40 + x * 0.1 = (x + 40) * 0.2

24 + 0.1x = 0.2x + 8

x = 160 liters

Answer: B) No, every x-value does not have exactly one y-value

Explanation:

We have the input x = 3 map to the outputs y = 2 and y = 8 at the same time. A function is only possible if any given x value goes to exactly one y value.

Put another way, if x repeats itself, then we don't have a function. This assumes we don't repeat the same y value when we repeat the x value.

Answer:

1) Use translation to coincide the center of a circle with the center of the other circle.

2) We construct the respective loci for the circles.

3) Compare each loci by direct inspection (\(f(x,y)\) must be the same and radii must be different but constant) to conclude the similarity of the two circles.

Step-by-step explanation:

Geometrically speaking, a circle is formed after knowing its center and radius.

1) Use translation to coincide the center of a circle with the center of the other circle. In this case, we translate the center (\(C_{A} (x,y) = (6,7)\)) of the circle A to the location of the center of the circle B (\(C_{B}(x,y) = (2,4)\)):

\(C_{A'} (x,y) = (6,7) + [(2,4) - (6,7)]\)

\(C_{A'} (x,y) = (2,4)\)

2) We construct the respective loci for the circles.

By Analytical Geometric, a circle is represented by the following locus:

\((x-h)^{2}+(y-k)^{2} = r^{2}\)

Where:

\(x, y\) - Coordinates of a point of the circunference.

\(h, k\) - Coordinates of the center of the circle.

\(r\) - Radius of the circle.

3) Compare each loci by direct inspection (\(f(x,y)\) must be the same and radii must be different but constant) to conclude the similarity of the two circles.

Then, the circles A' and B are represented by the following loci:

Circle A'

\((x-2)^{2} + (y-4)^{2} = 16\)

Circle B

\((x-2)^{2} + (y-4)^{2} = 256\)

Since both the \(f(x,y)\) component of each circle is the same and radii are different but constant, then we conclude that circle A is similar to circle B.

If a=4, b=6, and sina=3/5 in triangle abc, then sin b equals: 9/10

To find sin(b) in triangle ABC, we can use the sine function in a right angle and the given information.

Given:

a = 4

b = 6

sin(a) = 3/5

We know that the sine of an angle in a right triangle is equal to the ratio of the length of the side opposite the angle to the length of the hypotenuse.

In triangle ABC, let's label the side opposite angle a as side c and the hypotenuse as side h.

sin(a) = c / h

Substituting the given values:

3/5 = 4 / h

To solve for h, we can cross-multiply:

3h = 5 * 4

3h = 20

h = 20 / 3

Now, we can use the sine function to find sin(b):

sin(b) = side opposite angle b / hypotenuse

sin(b) = 6 / (20 / 3)

sin(b) = 6 * (3 / 20)

sin(b) = 18 / 20

sin(b) = 9 / 10

Therefore, sin(b) equals 9/10.

Answer:

Paul Revere’s famous ride on April 18th, 1775 is the subject of this famous Longfellow poem. It is told from the perspective of a landlord who is hoping to entertain and inform his “children”. ‘Paul Revere’s Ride’ was published in Atlantic Monthly magazine in 1861 around the beginning of the Civil War. Longfellow wrote this piece with the intent of inspiring Northerners.

One of the less discussed elements of this poem is its function as an anti-slavery statement. There are several allusions in this poem, such as to a burial ground for enslaved people and the use of the name “Somerset” at the beginning of the poem. The latter is connected to a landmark case that outlawed slavery in Britain in 1772.

Step-by-step explanation:

The s-orbital is spherical in shape, while the p-orbitals are composed of two lobes that are directed at an angle of 120 degrees apart.

It is composed of three atomic orbitals: one s-orbital and two p-orbitals. The s-orbital is spherical in shape, while the p-orbitals are composed of two lobes that are directed at an angle of 120 degrees apart. The combination of these three orbitals forms a hybrid orbital that is shaped like a flat trigonal planar, with a bond angle of 120 degrees. This hybrid orbital is known as the sp2 hybrid orbital.

The "s" in sp2 stands for the s-orbital, which is a single, spherical orbital. The "p" represents the two p-orbitals, which have two lobes and form an angle of 120 degrees with each other. The "2" in sp2 indicates that two p-orbitals are involved in the hybridization process. The hybridization of the s and two p-orbitals creates the sp2 hybrid orbital, which is trigonal planar in shape.

(a) State the parameter our confidence interval will estimate: Population mean

(b) Confidence interval because we have information about the sample mean and the sample standard deviation.

(c) Mean is $134 and margin error is \(1.645 \times \left(\frac{15}{\sqrt{n}}\right)\)

(d) Confidence interval is \(134 \pm 1.645 \times \left(\frac{15}{\sqrt{n}}\right)\)

A confidence interval is a range of values that is used to estimate an unknown population parameter with a certain level of confidence. It provides a range of plausible values for the parameter based on the observed data from a sample.

(a) The parameter that our confidence interval will estimate is the population mean daily fee collected in the new parking garage.

(b) A confidence interval for the population mean can be constructed because we have information about the sample mean and the sample standard deviation, which allows us to estimate the population mean with a certain level of confidence.

(c) To find the mean and the margin of error for a 90% confidence interval, we can use the formula for the margin of error:

\(\[ \text{Margin of Error} = \text{Critical Value} \times \left(\frac{\text{Standard Deviation}}{\sqrt{\text{Sample Size}}}\right) \]\)

The critical value is determined by the desired confidence level and the distribution of the data. For a 90% confidence interval, the critical value for a normally distributed population is approximately 1.645.

Using the given information, the mean is $134 (the sample mean) and the standard deviation is $15 (treated as the population standard deviation). Since the sample size is not mentioned, we'll assume a large sample size for the calculation.

Plugging these values into the formula, we get:

\(\[ \text{Margin of Error} = 1.645 \times \left(\frac{15}{\sqrt{n}}\right) \]\)

(d) To put all the pieces together for a 90% confidence interval for the mean revenue amount, we need to calculate the lower and upper bounds of the interval.

The lower bound is the sample mean minus the margin of error, and the upper bound is the sample mean plus the margin of error.

Since we don't have the sample size, we can't compute the exact margin of error or the confidence interval. However, assuming a large sample size, we can use the approximation:

\(\[ \text{Confidence Interval} = \text{Sample Mean} \pm \text{Margin of Error} \]\)

For a 90% confidence interval, the z-value for a normally distributed population is approximately 1.645. Using the formula for the margin of error from earlier, we can approximate the confidence interval:

\(\[ \text{Confidence Interval} = 134 \pm 1.645 \times \left(\frac{15}{\sqrt{n}}\right) \]\)

To calculate the annual earnings with a 90% confidence interval, we need to consider the number of days in a year. Assuming 365 days in a year, we can multiply the daily revenue by 365:

\(\[ \text{Annual Earnings} = 365 \times \text{Daily Revenue} \]\)

Since we don't have the exact confidence interval for the daily revenue, we can't compute the precise range for the annual earnings. However, using the approximate confidence interval for the daily revenue, we can apply the same approach to estimate the range for the annual earnings.
