It says that raise school is 1. 7 miles from his house the student walks 17 miles in a 5-day school week

If the school is 1.7 miles from the student's house, then the round trip distance between the house and school is 2 times 1.7 miles, or 3.4 miles per day.

A mile is defined as the unit of length, which is exactly equal to 5280 feet, or 1760 yards, and standardized as exactly 1609.344 meters by the International agreement in 1959. It is the largest unit that is commonly used to measure the distance between places that are far from each other.

To find out how many miles the student walks in a 5-day school week, we can multiply the daily distance by the number of school days in a week:

3.4 miles/day x 5 days/week = 17 miles/week

Therefore, the student walks 17 miles in a 5-day school week

The expression for f(x) - g(x) - h(x) is 6x - 5x² + 6.

Option C is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 3x + 5

g(x) = 4x² - 2

h(x) = x² - 3x + 1

Now,

f(x) - g(x) - h(x)

= 3x + 5 - (4x² - 2) - (x² - 3x + 1)

= 3x + 5 - 4x² + 2 - x² + 3x - 1

= 6x - 5x² + 6

It took Bunolo 100 minutes (or 1 hour and 40 minutes) to complete the 10 km race at an average speed of 6 km/h.

To find out how long it took Bunolo to complete a 10 km race with an average speed of 6 km/h, we can use the formula:

time = distance / speed

where "distance" is the distance of the race and "speed" is the average speed at which Bunolo ran. We can convert the speed to km/minute to get the time in minutes.

To do this, we can divide the speed in km/hour by 60 (the number of minutes in an hour) to get the speed in km/minute:

6 km/hour ÷ 60 minutes/hour = 0.1 km/minute

Now, we can substitute the distance and speed values into the formula to get the time in minutes:

time = 10 km / 0.1 km/minute = 100 minutes

The correct answer is 45.28°

In order to get that answer, you must set up the arc length formula.

l = m/360 • 2πr

4.9 = m/360 • 12.4π

We are trying to find the angle measure; therefore, we are going to divide.

4.9 = 0.10821m

Flip the equation

0.10821m = 4.9

0.10821m/0.10821 = 4.9/0.10821

m = 45.28°

We can use the formula angle = (arc length / radius) or an online calculator to find the angle of the slice, which is approximately 47 degrees in this case.

To find the measure of the angle of one slice of pizza, we can use the formula:

angle = (arc length / radius)

However, we are not given the radius of the pizza, so we first need to find it. One way to do this is to use the length of one side of the slice and the central angle of the slice. We know that the central angle of the slice is twice the angle at the center of the pizza that the slice occupies, so we can find this angle by:

angle at center = (angle of slice) / 2

We can then use the law of cosines to find the length of the radius:

radius² = (side length / 2)^2 + (side length / 2)² - 2 * (side length / 2) * (side length / 2) * cos(angle at center)

Once we have the radius, we can use the formula above to find the angle of the slice. However, since this calculation can be quite involved, it may be simpler to use an online pizza slice angle calculator. Using this tool with the given values, we find that the angle of one slice of pizza is approximately 47 degrees.

Answer:

The function f: A -> B is defined by:

f(x) = { 11, if x = -1 or x = 2,

-1, if x = 0,

-2, if x = 1,

0, if x = 3 or x = 4 }

The range of the function is the set of all possible values of f(x). In this case, the range of f is B = {-2, -1, 0, 11}.

To determine if the function is one-to-one, we need to check if each element in the range has only one pre-image. In other words, we need to check if no two elements in A map to the same element in B. Since each element in B has a unique pre-image in A, the function is one-to-one.

To determine if the function is onto, we need to check if each element in B is the image of some element in A. In this case, every element in B is the image of exactly one element in A, so the function is onto.

Therefore, the function f is one-to-one and onto both.

Answer:

  Two solutions:

Step-by-step explanation:

Given right ΔABC, with tan(A) = 3/2 and b = 5, you want the exact lengths of sides a and c.

To completely solve a triangle, you need to know at least one side, at least one angle, and one other side or angle. Here, we're given one side and one angle, so cannot solve the triangle using the given information.

We know another angle is 90°, but we don't know which one.

Often, side c is the one designated as the hypotenuse, but that is not necessarily the case. So, there are two solutions.

This case corresponds to the red triangle shown in the attachment.

In this triangle, the leg adjacent to angle A is side b, so we have ...

  Tan = Opposite/Adjacent . . . . . trig relation

  3/2 = a/5

  a = 15/2

The Pythagorean theorem can be used to find the length of side c.

  c² = a² +b²

  c² = (15/2)² +5² = 225/4 +25 = 325/4

  c = √(325/4)

  c = (5/2)√13

This case corresponds to the blue triangle shown in the attachment.

The given tangent of angle A tells us the ratio ...

  Tan = Opposite/Adjacent

  3/2 = a/c

  a = 3/2c . . . . . multiply by c

The Pythagorean theorem tells us ...

  b² = a² +c²

  5² = (3/2c)² +c² = 13/4c² . . . . . . substitute for b and a

  c² = (4/13)(5²) = (10/13)²·13 . . . . . . multiply by 13/13

  c = (10√13)/13 . . . . . . . . . . . . square root

  a = 3/2c = (15√13)/13 . . . . . . find 'a'

The sample mean is 89.45, the sample standard deviation is 2.327, and the sample median is 91 and the leaf plot of the data is illustrated below.

The sample standard deviation is a measure of how much the ratings vary from the sample mean. It tells us how spread out the data is. A larger standard deviation means the data is more spread out, while a smaller standard deviation means the data is more tightly clustered around the mean.

To calculate the sample standard deviation, we first need to calculate the variance. The variance is the average of the squared differences between each rating and the mean. The formula for variance is:

variance = (sum of (rating - mean)²) / (number of ratings - 1)

In this case, the sum of the squared differences is 301.9, and there are 39 degrees of freedom (40 ratings minus 1), so the variance is 7.741. To get the sample standard deviation, we take the square root of the variance. In this case, the sample standard deviation is approximately 2.78.

The sample median is the middle rating when the ratings are arranged in order from lowest to highest. In this case, there are 40 ratings, so the median is the average of the 20th and 21st ratings, which are both 91.

Finally, we can determine what proportion of the taste-tasters considered this particular pinot noir truly exceptional (above 90 points). To do this, we count the number of ratings that are above 90 and divide by the total number of ratings. In this case, there are 30 ratings above 90, so the proportion is 30/40, or 0.75. This means that 75% of the taste-tasters considered this pinot noir truly exceptional.

They have a distance of 10, therefore a radius of 5

Since the vertical axis is bigger, we have a vertical ellipse which is the equation of,

[tex] \frac{(y - k) {}^{2} }{ {a}^{2} } + \frac{(x - h) {}^{2} }{ {b}^{2} } = 1[/tex]

Where a is the major radius

b is the minor radius

(h,k) is the center

Step 1: Finding the center

The center should be the midpoint of the horizontal vertices or vertical vertices

Let's use the horizontal vertices

[tex] (\frac{(0 + 4}{2} ) = 2[/tex]

[tex]( \frac{8 + 8}{2} ) = 8[/tex]

So the center is (2,8)

Step 2: Finding the major and minor radius

We already know it , a is 5

b is 2, so we as of now, have this equation

[tex] \frac{(y -8) {}^{2} }{25} + \frac{(x - 2) {}^{2} }{4} = 1[/tex]

This is the equation of the ellisoe

Step 3: Find the foci

The foci for a vertical ellipse should lie on the same line as the same line as the major vertices and center.

The equation for an ellipse foci that is vertical are

(x,y+c) and (x,y-c)

Where C is

[tex]c = \sqrt{ {a}^{2} - {b}^{2} } [/tex]

[tex]c = \sqrt{25 - 4} [/tex]

[tex]c = \sqrt{21} [/tex]

So our foci are

,,,

[tex](2,8 + \sqrt{21} )[/tex]

and

[tex](2,8 - \sqrt{21} )[/tex]

,

Step-by-step explanation:

inversely means

y = k/x

therefore

30 = k/4

120 = k

y = 120/10 = 12

FYI :

directly would mean

y = kx

The value of y will be 12 when x is equal to 10.

The relationship between two variables known as "inverse variation" occurs when the value of one variable increases while the value of the other variable decreases.

Given that, y varies inversely with x.

Here, y∝1/x

y=k/x

xy=k

When x is 4, y is equal to 30, we get

k=4×30

k=120

When x=10, we get

10y=120

y=12

Therefore, the value of y will be 12 when x is equal to 10.
