The force “F” (in pounds) needed on a wrench handle to loosen a certain bolt varies inversely with the length “L” (in inches) of the handle. A force of 35 pounds is needed when the handle is 6 inches long. If a person needs 25 pounds of force to loosen the bolt, estimate the length of the wrench handle. Round answer to two decimal places if necessary.


______ inches.

Answers

The length of the wrench handle 8.4 inches.

What is length?

Distance is measured in length. Length has the dimension of distance in the International System of Quantities. The majority of measurement systems choose a base unit for length from which all other units are derived. The metre serves as the foundational unit of length in the International System of Units.

f = k/l

35 = k/6        

k = 210

f = 210/l

A lemonade recipe calls for the juice of 5 lemons, 2 cups of water, and 2 tablespoons of honey.
Invent four new versions of this lemonade recipe:
1: One that would make more lemonade but tastes the same as the original recipe.
2: One that would make less lemonade but taste the same as the original recipe.
3: One that would have a stronger lemon taste than the original recipe
4: One that would have a weaker lemon taste than the original recipe.

Answers

Since the lemonade recipe calls for the juice of 5 lemons, 2 cups of water, and 2 tablespoons of honey we can use mathematical operations to make different lemonades with the following recipes:

1) To make more lemonade taste the same as the original, we can use the multiplication operation on the above recipe as follows:

Lemons = 10

Cups of water = 4

Tablespoons of honey = 4

2) To make less lemonade taste the same as the original recipe, we can use the division operation as follows:

Lemons = 2.5

Cups of water = 1

Tablespoons of honey = 1

3) To make lemonade that has a stronger lemon taste than the original recipe, we can use the subtraction operation as follows:

Lemons = 4

Cups of water 1

Tablespoons of honey

4) To make lemonade that has a weaker lemon taste than the original recipe, we can use the addition operation as follows:

Lemons = 6

Cups of water 3

Tablespoons of honey = 3

Original Lemonade Recipe:

Lemons = 5

Cups of water = 2

Tablespoons of honey = 2

1) Using the multiplication operation to make more lemonade taste the same as the original:

Lemons = 10 (5 x 2)

Cups of water = 4 (2 x 2)

Tablespoons of honey = 4 (2 x 2)

2) Using the division operation to make less lemonade taste the same as the original recipe:

Lemons = 2.5 (5 ÷ 2)

Cups of water = 1 (2 ÷ 2)

Tablespoons of honey = 1 (2 ÷ 2)

3) Using the subtraction operation to make lemonade that has a stronger lemon taste than the original recipe:

Lemons = 4 (5 - 1)

Cups of water 1 (2 - 1)

Tablespoons of honey = 1 (2 - 1)

4) Using the addition operation to make lemonade that has a weaker lemon taste than the original recipe:

Lemons = 6 (5 + 1)

Cups of water 3 (2 + 1)

Tablespoons of honey = 3 (2 + 1)

The linear functions in this problem are given as follows:

1. y = 1/3x + 3.

2. y = 2.

3. y = 3x - 1.

4. x = 1.

How to define the linear functions?

The slope-intercept definition of a linear function is presented as follows:

y = mx + b.

In which the coefficients are given as follows:

m is the slope.b is the y-intercept.

For item 1, the points are given as follows:

(-6, 1) and (-3,2).

When x increases by 3, increases by 1, hence the slope is given as follows:

m = 1/3.


Then:

y = 1/3x + b.

When x = -3, y = 2, then the intercept b is calculated as follows:

2 = 1/3(-3) + b

b = 3.

Thus the function is:

y = 1/3x + 3.

Then items 2 and 4 are given as follows:

2 -> horizontal line -> y = 2.4 -> vertical line -> x = 1.

For item 3, we have an intercept of -1, hence:

y = mx - 1.

When x = 3, y = 8, hence the slope m is calculated as follows:

8 = 3m - 1

3m = 9

m = 3.

Hence the function is:

y = 3x - 1.

A relation is a specific instance of a function graph. A function is truly equivalent to its graph in set theory and the current mathematical underpinnings.

It is frequently more helpful to think about functions as mappings, which include the sets that constitute the domain and the codomain in addition to the relationship between input and output. For instance, the codomain should be considered while determining if a function is onto (surjective) or not. The codomain of a function is not determined by the graph alone.

The months when the temperature will be 0 °C are May and August.

What is a trigonometric function?

A trigonometric function is a function that has the trigonometric ratios.

What is temperature?

Temperature is the degree of hotness or coldess of a body.

How to find the months in which the temperature is zero degrees?

Since the average monthly temperature of a particular city is T(m) = 10cos(πm/6) + 5 where m = number of months of year and January begins at m = 0.

To find the number of months in which the temperature would be 0°C. This means T(m) = 0.

So,  T(m) = 10cos(πm/6) + 5

0 = 10cos(πm/6) + 5

-10cos(πm/6) = 5

cos(πm/6) = 5/10

cos(πm/6) = -0.5

cos⁻¹cos(πm/6) = cos⁻¹(-0.5)

(πm/6) = π - π/6 or (πm/6) = 3π/2 - π/6 (since cos is negative int he second and third quadrant respectively)

πm/6 = 5π/6 or πm/6 = 8π/6

⇒ m = 5π/6 × 6/π or m = 8π/6 × 6/π

⇒ m = 5 or m = 8

Since m = 5 is May and m = 8 is August,

The months when the temperature will be 0 °C are May and August.

What is the slope of a line parallel to the line whose equation is 3x-2y=14

Answers

Answer: 3/2

Step-by-step explanation:

3x - 2y = 14

-2y = 14-3x

y = 3/2x-7  divide both sides by -2

Dominique throws a softball from the outfield. After 1 second, the ball is 15 feet high. After 4 seconds, the ball reaches its maximum height of 42 feet. After 7 seconds, it returns to a height of 15 feet. What is the equation of the quadratic function that models the height of the ball h(t) at time t? h(t) = −2(t − 4)2 + 42 h(t) = 2(t + 4)2 + 42 h(t) = −3(t − 4)2 + 42 h(t) = 3(t + 4)2 + 42

Answers

The equation of the quadratic function that models the height of the ball h(t) at time t is h(t) = −3(t − 4)² + 42

How to determine the equation of the height function?

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

Height after 1 second = 15 feetHeight after 7 seconds = 15 feetMaximum height = 42 feet

The above parameters mean that

h(1) = 15

h(7) = 15

h max = 42

This also means that the leading coefficient of the function is negative

So, the possible equations from the options are

h(t) = −2(t − 4)² + 42

h(t) = −3(t − 4)² + 42

Calculate h(1) and h(7)

h(t) = −2(t − 4)² + 42

h(1) = −2(1 − 4)² + 42 = 24

h(7) = −2(7 − 4)² + 42 = 24

h(t) = −3(t − 4)² + 42

h(1) = −3(1 − 4)² + 42 = 15

h(7) = −3(7 − 4)² + 42 = 15

Hence, the function is h(t) = −3(t − 4)² + 42

Line q has an equation of y+7=9(x+4). Line r is perpendicular to line q and passes through (9,–10). What is the equation of line r?

Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.

Answers

Answer:

Y= -1/9x-9 that's the answer, you're welcome

The equation of line which is perpendicular to the line q is given by

y = ( -1/9 )x - 9

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The point is P ( 9 , -10 )

Let the equation of line q be  y + 7 = 9 ( x + 4 )

Now , on simplifying the equation , we get

y + 7 = 9x + 36

Subtracting 7 on both sides of the equation , we get

y = 9x + 29

Now , the slope of the equation q is m₁ = 9

Now , since the line r is perpendicular to line q

The product of the slope is -1

So , m₁ x m₂ = -1

Substituting the values in the equation , we get

9 x m₂ = -1

Divide by 9 on both sides of the equation , we get

m₂ = -1/9

So , the slope of the line r m₂ = -1/9

The equation of line is given by y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - ( -10 ) = -1/9 ( x - 9 )

On simplifying the equation , we get

y + 10 = -1/9 ( x - 9 )

y + 10 =  ( -1/9 )x + 1

Subtracting 10 on both sides of the equation , we get

y = ( -1/9 )x - 9

Therefore , the value of A is y = ( -1/9 )x - 9

Hence , the equation of line r is y = ( -1/9 )x - 9
