The straight line shown below passes through the points (3, 1) and (8, 36).
What is the gradient of this line?
Give your answer as an integer or as a fraction in its simplest form.

Answers

Answer 1

Answer:

the gradient of the line is 7.

Step-by-step explanation:

To find the gradient of the straight line that passes through the points (3,1) and (8,36), we use the formula:

Gradient = (change in y) / (change in x)

The change in y is the difference between the y-coordinates of the two points, which is:

36 - 1 = 35

The change in x is the difference between the x-coordinates of the two points, which is:

8 - 3 = 5

Therefore, the gradient of the straight line is:

Gradient = (change in y) / (change in x) = 35 / 5 = 7

So the gradient of the line is 7.

Why is GDP an imperfect measure of economic well-being? What types of production does GDP not measure? If GDP included these types of production, would it still be an imperfect measure of economic well-being?

Answers

The reasons behind GDP is an imperfect measure of economic well being are value of goods and services , economic activity, distributional issues, and depletion of natural resources .

GDP (Gross Domestic Product) is an imperfect measure of economic well-being for several reasons.

First,

GDP only measures the monetary value of goods and services produced within a country's borders.

It does not take into account non-market activities such as household work or volunteer work,

This can be significant contributors to well-being but are not included in GDP calculations.

Second,

GDP does not distinguish between desirable and undesirable economic activity.

For example, expenditures on environmental cleanup or healthcare are counted in GDP

Just as much as expenditures on cigarettes or military weapons.

Even though the former are beneficial for society, while the latter are not.

Third,

GDP does not measure distributional issues such as inequality, poverty, or social welfare.

Even if GDP were to increase,

It does not necessarily mean that all citizens have benefited equally from the economic growth.

Fourth,

GDP does not account for the depletion of natural resources or damage to the environment.

While economic growth may be achieved through unsustainable or environmentally destructive practices.

These costs are not reflected in GDP calculations.

Finally,

GDP does not capture the value of intangible factors such as social cohesion, quality of life, or happiness.

If GDP were to include non-market activities such as household work.

It would provide a more accurate measure of overall economic activity.

However, GDP would still be an imperfect measure of economic well-being.

Because it would not account for the distributional issues or environmental factors mentioned earlier.

Additionally, including non-market activities could potentially create new problems.

Answers

The distance across the lake, given the distance of the tree and Cade would be 14.36 ft.

How to find the distance ?

We can use the concept of similar triangles to solve this problem:

(Length of the tree's shadow) / (Distance from the tree to the edge of the lake) = (Length of Cade's shadow) / (Cade's height)

36.2 / 15 = 2.5 / 6.2

Now we can set up another proportion using the length of the tree's shadow and the length of the lake:

(Length of the tree's shadow) / (Length of the lake) = (Distance from the tree to Cade) / (Length of Cade's shadow)

Plugging in the values we know, we get:

Ines's younger brother will be home in a half hour. If her garden hose flows at a rate 24​ gal/min, does she have enough time to fill the pool before he gets​ home? Explain. ​

Answers

No, she have not enough time to fill the pool before he gets home. The garden hose with flow rate 24 gal/min will take 40 minutes to complete fill up the tank that is t ~ 40 minutes. So, she cannot complete fill up the pool before he come.

We have, the time in which Ines's younger brother will be home = an half hour = 1/2 hour

water flow rate of garden's hose = 24 gal/min

She want to fill up the pool. From the figure, depth of pool = 3 ft

Width of pool = 10 in.

1 inch = 0.0833 feet

So, 10 inches = 0.833 feet

outer diameter of pool = 9 ft

so, outer radius of pool = 4.5 ft

Now, inner diameter of pool/tank = outer diameter - 2(width)

= 9 - 2×0.833

= 9 - 1.666 = 7.334

Inner radius of pool = 7.334/2 = 3.667 ft

Water flow rate, Q = 24 gal/min

= 24/7.48 gal ( since 1 ft³ = 7.48 gal)

= 3.20 ft³

Using formula, Q = volume/ time

where t --> time to fill up the pool through hose

Volume of tank/pool = surface area × height (depth)

= π r² × h , where r is inner radius

= π (3.667)² × 3 ft³

= 126.71 ft³

So, Q = 126.71 ft³/t

=> t = 126.71 ft³/3.20 ft³

=> t = 39.59 min

Hence, required time is 39.59 ~ 40 minutes and she cannot complete before he come.

Answers

The equation of line perpendicular to y = -4x and passing through the point (12, 6) is y = 1/4 x + 3.

How to determine a line's equation from two points?

Using the slope method, determine the slope.

To find the y-intercept (b), use the slope and one of the locations.

You can obtain the equation for a line by entering the values of m and b into the slope-intercept form of the line (y = mx + b).

The given equation is y = -4x and we need to find the equation of the line which is passing through the point (12,6).

As y=-4x, therefore compared to the standard equation y = mx, hence the slope of the line is m = -4.

Therefore any line which is perpendicular and has a slope that is the negative reciprocal of the -4 is 1/4.

The modified equation becomes for the line that passes through (12, 6).

y-6 = 1/4 (x-12)

solving this equation we get,

y-6 = 1/4 x - 1/4 * 12

y-6 = 1/4 x - 3

y = 1/4 x -3 + 6

y = 1/4 x + 3

[tex]\mu[/tex] is the mean in the given interval.

There is a 17.18% probability that a randomly selected region had exactly two hits.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X=x)=\dfrac{e^{-\mu}\times\mu^x}{(x)!}[/tex]

Which team had the best overall record for the season? Determine the best measure of center to compare and explain your answer. Cowboys; they have a larger median value of 10 points
Saints; they have a larger median value of 12 points
Cowboys; they have a larger mean value of about 12. 2 points
Saints; they have a larger mean value of about 14 points

Answers

The Saints had the best overall record for the season because they had a larger mean value of about 200 points, whereas the Saints had a larger median value of 12 points.

To determine which team had the best overall record for the season, we need to consider the total number of points earned by each team across all games. We can calculate the total points for each team by adding up the points earned in each game.

For the Saints:

Total points = 21+12+3+3+10+10+14+3+12+28+40+10+17+20+7 = 200

For the Cowboys:

Total points = 10+3+8+6+24+12+21+3+10+28+28+7+7+13+3 = 183

Therefore, the Saints earned a total of 200 points, while the Cowboys earned a total of 183 points. Therefore, the Saints had the better overall record for the season.

To compare the central tendency of the points earned by each team, we can use either the mean or the median. However, in this case, the median is a better measure of center because it is less sensitive to extreme values than the mean.

Calculating the median for each team:

For the Saints:

Arrange the points earned in ascending order: 3 3 7 10 10 12 12 14 17 20 21 28 40

The median value is the middle value, which is 12.

For the Cowboys:

Arrange the points earned in ascending order: 3 3 6 7 8 10 10 12 13 21 24 28

The median value is the middle value, which is 10.

Therefore, the Cowboys have a median value of 10 points, while the Saints have a median value of 12 points. However, as we already determined, the Saints had a better overall record for the season based on the total points earned.

Naomi went shopping for a new pair of sneakers because of a sale. The store was offering a 10% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?

Answers

She should multiply the prices on the tags by 0.9 to find the price she would have to pay, before tax, after the 10% discount.

To find the price Naomi would have to pay for her new sneakers after the 10% discount, she needs to multiply the original price on the tag by a factor that reflects the discount.

Since the discount is 10%, the factor by which she should multiply the original price is 1 minus 10% or 0.9. This is because the final price is equal to the original price minus the discount, which is 10% of the original price, or 0.1 times the original price.

So, if the price on the tag is $100, the price Naomi would have to pay, before tax, after the 10% discount would be:

$100 * 0.9 = $90

This means that she would save $10, which is 10% of the original price.

In general, if the original price on the tag is P, the price Naomi would have to pay, before tax, after the 10% discount would be:

P * 0.9 = 0.9P

In geometry, a tangent of a circle is a straight line that intersects the circle at exactly one point, which is known as the point of tangency. The tangent line is perpendicular to the radius of the circle at the point of tangency.

An angle is a geometric figure formed by two rays that share a common endpoint, known as the vertex. Angles are usually measured in degrees or radians and are commonly used to describe the direction or orientation of lines, shapes, or objects in space.

we do know that the angle between the tangent and the radius drawn to the point of tangency is 90 degrees. We can use this fact to set up an equation and solve for x:

Answers

According to the question we can conclude that the total mass of the jars is 2.561 g.

Explain law of mass conversion?

The mass is the amount of matter in an object. It is measured in grams, kg, ect. According to the law of conservation, mass in such an isolated system may only be changed through one form to another and cannot be created or destroyed.

To find the total mass of the jars, we simply need to add up the masses of jar one, jar two, and jar three:

Total mass of jars = mass of jar one + mass of jar two + mass of jar three

Total mass of jars = 0.62 g + 1.431 g + 0.5 g

Total mass of jars = 2.561 g

So the total mass of the jars is 2.561 g.

If my friend went to bed at 1:00am on Friday. Then she woke up at 1:00pm on Friday how many hours of sleep did she get?

Answers

If your friend went to bed at 1:00am on Friday and woke up at 1:00pm on Friday, she slept for 12 hours.

To see why, you can count the number of hours between 1:00am and 1:00pm:

1:00am to 2:00am = 1 hour

2:00am to 3:00am = 1 hour

...

11:00am to 12:00pm = 1 hour

12:00pm to 1:00pm = 1 hour

The total number of hours between 1:00am and 1:00pm is 12 hours.

a new car is purchased for 18500 dollars. the value of the car depreciates at 8% per year. to the nearest tenth of a year, how long will it be until the value of the car is 9100 dollars?

Answers

Answer:

  8.5 years

Step-by-step explanation:

You want to know the number of years until 18500 depreciates to 9100 at the rate of 8% per year.

Value

The depreciation rate given as a percentage of current value tells you the depreciation is exponential. The formula will be ...

  value = (initial value) × (1 - (depreciation rate))^t

where the rate is "per year" and t is in years.

Application

  value = 18500·(1 -0.08)^t

  9100 = 18500·0.92^t . . . . fill in the value of interest

  9100/18500 = 0.92^t . . . . divide by 18500

  log(91/185) = t·log(0.92) . . . . take logarithms

  t = log(91/185)/log(0.92) ≈ -0.3081/-0.03621 ≈ 8.509

It will be about 8.5 years until the value is $9100.

Additional comment

The graph shows the solution to ...

  18500·0.92^t -9100 = 0

The arithmetic mean of 25, 29, and x is 29. Find x.

Answers

The formula for the arithmetic mean is:

(mean) = (sum of terms) / (number of terms)

In this case, we know that the mean is 29 and there are three terms (25, 29, and x). So, we can write:

29 = (25 + 29 + x) / 3

Multiplying both sides by 3, we get:

87 = 25 + 29 + x

Simplifying, we get:

87 = 54 + x

Subtracting 54 from both sides, we get:

x = 33

Therefore, the missing number is x = 33.

you have been asked to design a can shaped like right circular cylinder that can hold a volume of 432⇡-cm3. what dimensions of the can (radius and height) will use the least amount of material?

Answers

The dimensions of the can that use the least amount of material are a radius of approximately 4.38 cm and a height of approximately 3.11 cm.

To design a can that uses the least amount of material, we want to minimize its surface area. Since the can is shaped like a right circular cylinder, its surface area is given by:

A = 2πr² + 2πrh

where r is the radius of the base of the cylinder and h is its height.

We also know that the volume of the can is given by:

V = πr²h

We can use these equations to express h in terms of r, and then substitute this expression for h into the equation for surface area. Then we can differentiate the resulting equation with respect to r, set it equal to zero, and solve for r to find the value of r that minimizes surface area.

First, we solve for h in terms of r by rearranging the equation for volume:

h = V/(πr²)

Substituting this expression for h into the equation for surface area, we get:

A = 2πr² + 2πr(V/(πr²))

A = 2πr² + 2V/r

To minimize A, we differentiate with respect to r:

dA/dr = 4πr - 2V/r²

Setting this expression equal to zero and solving for r, we get:

4πr = 2V/r²

r³ = V/(2π)

Substituting the given value for V, we get:

r³ = 432/2π

r ≈ 4.38 cm

Now we can use the expression for h in terms of r to find the corresponding height:

h = V/(πr²) ≈ 3.11 cm

Therefore, the dimensions of the can that use the least amount of material are a radius of approximately 4.38 cm and a height of approximately 3.11 cm.

Circumference=14.4
Area =?

Answers

Answer:

[tex]a = \frac{1296}{5\pi} [/tex]

Step-by-step explanation:

Given:

C = 14,4 (circumference)

Find: A - ? (area)

Let's start by writing down both circumference and area formulas:

[tex]c = 2\pi \times r[/tex]

[tex]a = \pi \times {r}^{2} [/tex]

We can find the radius (r) from the 1st formula:

[tex]r = \frac{c}{2\pi} = \frac{14.4}{2\pi} =14 \frac{4}{10} \times \frac{1}{2\pi} = \frac{144}{10} \times \frac{1}{2\pi} = \frac{144}{20\pi} = \frac{36}{5\pi} [/tex]

Now, that we know the length of the radius, we can find the area:

[tex]a = \pi \times( { \frac{36}{5\pi} })^{2} = \frac{1296}{25 {\pi}^{2} } \times \frac{\pi}{1} = \frac{1296}{25\pi} [/tex]
