Greg has a 15 foot ladder. He needed to clean his gutters which are 12 feet high from the ground. How far away does Greg need to place the ladder from the base of the house to reach the gutters

Answers

Answer:

Base = 81 feet

Step-by-step explanation:

Given that,

Length of the ladder = 15 foot

Greg needed to clean his gutters which are 12 feet high from the ground.

We need to find how far away does Greg need to place the ladder from the base of the house to reach the gutters. Let it is b.

Here, hypotenuse = 15 feet, height = 12 feet and base = b

We can use Pythagoras theorem to find b.

[tex]b^2+h^2=H^2\\\\b^2=H^2-h^2\\\\b^2=15^2-12^2\\\\b^2=225-144\\\\b=81\ \text{feet}[/tex]

So, the ladder should be placed at a distance of 81 feet from the base of the house to reach the gutters.

What is the weight on Earth of a girl with a mass of 30 Kg? The acceleration due to gravity on Earth is 9.8 m/ s 2.

ex

Answers

Answer: If, on earth, your mass is 30kg, then your weight is m*g which is mass (30kg) times Earth gravity (9.8m/s^2) = 294 N.

Step-by-step explanation:

The weight of a girl would be 294 N on Earth with a mass of 30 Kg.

What are Arithmetic operations?

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

The weight on Earth of a girl would be the product of the mass and acceleration due to gravity on Earth

So the required solution would be:

⇒ weight  = mass × acceleration due to gravity on Earth

⇒ weight  = 30 × 9.8

⇒ weight  = 294 N.

Hence, the weight of a girl would be 294 N on Earth with a mass of 30 Kg.

solve for the y-intercept. Show your work! Then list the slope-intercept form of the line (-15,-17) (14,10)

Answers

Answer:

The line is y = 27/29x - 88/29The y-intercept is (0, -88/29)

Step-by-step explanation:

Given point:

(-15,-17), (14,10)

Slope-intercept form:

y = mx + b

Use slope formula:

m = (y₂ - y₁)/(x₂ - x₁)m = (10 - (-17))/(14 - (-15)) = 27/29

Use one of the points to find the y-intercept:

y = 27/29x + b10 = 27/29*14 + bb = (29*10 - 27*14)/29b = -88 /29

The line is:

y = 27/29x - 88/29

Answer:

slope for y intercept={10--17)/(14--15)=27/29

A bouncy ball is dropped such that the height of its first bounce is 6 feet and each successive bounce is 72% of the previous bounce's height. What would be the height of the 6th bounce of the ball? Round to the nearest tenth (if necessary).

Answers

Answer:1.2

Step-by-step explanation:

The height of the 6th bounce of the ball will be 1.2 feet.

What is geometric sequence?

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

What is the formula for finding the nth term of geometric sequence?

The nth term of the geometric sequence is given by

[tex]T_{n} =ar^{n-1}[/tex]

Where,

[tex]T_{n}[/tex] is the nth term.

r is the common ratio

a is the first term

According to the given question.

During the first bounce, height of the ball from the ground, a = 6 feet

And, the each successive bounce is 72% of the previous bounce's height.

So,

During the second bounce, the height of ball from the ground

= 72% of 6

= [tex]\frac{72}{100} (6)[/tex]

= 0.72 × 6

= 4.32 feet

During the third bounce, the height of ball from the ground

= 72% of 4.32

= [tex]\frac{72}{100} (4.32)[/tex]

= 3.11 feet

Like this we will obtain a geometric sequence 6, 4.32, 3.11, 2.23,...

And the common ratio of the geometric sequence is 0.72

Therefore,

The sixth term of the geometric sequence is given by

[tex]T_{6} = 6(0.72)^{6-1}[/tex]

[tex]T_{6} =6(0.72)^{5}[/tex]

[tex]T_{6} = 6 (0.193)[/tex]

[tex]T_{6} = 1.16 feet[/tex]

[tex]T_{6} = 1.2[/tex] feet

Hence, the height of the 6th bounce of the ball will be 1.2 feet.

What is obtuse triangle?

"It is a triangle whose one of the angles measure greater than 90° and other two acute angles."

What is law of sines?

"The ratio of the length of a side of a triangle to the sine of the angle opposite to that side is the same for all sides and angles in a given triangle."

For given question,

We have been given an obtuse triangle ABC.

Here, ∠B = 32°

∠C = 125°

We know that the sum of all angles of  a triangle is 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A + 32° + 125° =180°

⇒ ∠A = 23°

Using the law of sines to triangle ABC,

[tex]\Rightarrow \frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC} \\\\\Rightarrow \frac{7}{sin23^{\circ}} =\frac{b}{sin32^{\circ}} =\frac{c}{sin125^{\circ}}[/tex]

Consider,

[tex]\Rightarrow \frac{7}{sin23^{\circ}} =\frac{b}{sin32^{\circ}} \\\\\Rightarrow \frac{7}{0.39} =\frac{b}{0.53} \\\\\Rightarrow 7\times 0.53=b\times 0.39\\\\\Rightarrow b = 9.5[/tex]

Now we find the length of the side AB.

[tex]\Rightarrow \frac{7}{sin23^{\circ}} =\frac{c}{sin125^{\circ}} \\\\\Rightarrow \frac{7}{0.39} =\frac{c}{0.82} \\\\\Rightarrow 7\times 0.82=c\times 0.39\\\\\Rightarrow c = 14.72[/tex]

Therefore, the missing values are:

A = 23°

b = 9.5

The amusement park has two plans available for the school to choose from. Plan A is listed in the table below.


Cost (per vehicle) = $10
Cost (per person) = $30


The cost of Plan B can be calculated using the formula c = $15v + $28p, where c represents the cost, v represents the number of vehicles, and p represents the number of people. The school has a budget of $7200 for the cost of tickets and parking. If 241 students are going on the field trip, which plan should the school purchase? Explain your reasoning.

Answers

Answer:

the second plan should be purchased.

Step-by-step explanation:

school budget is $7200

plan 1: 241 students are $30 each is

241 × 30 = $7230 which is over budget with no money for parking for the vehicles.

plan 2: 241 students are $28 each is

241 × 28 = $6748

with a budget of $7200 for the trip the amount left for parking is

$7200 - $6748 = $452

plan 2: Parking is $15 per vehicle

Therefore the remaining $452 can be used to pay for 452 ÷ 15 = 30.13 vehicles

The school should purchase Plan 2 for the field trip.

The budget of $7200 can pay for 241 tickets for students and parking for 30 vehicles

The school should purchase the second plan.

School's budget = $7200

The cost for the first plan will be:

= 241 × $30

= $7230

This is more than the school budget of $7200

For the second plan, the cost will be:

= 241 × $28

= $6748.

This is below the school budget and therefore affordable.

The school should choose the second plan as there'll be more money available for parking.

A vehicle moves along a straight road. The vehicle's position is given by f(t), where t is measured in seconds since the vehicle starts moving. During the first 10 seconds of the motion, the vehicle's acceleration is proportional to the cube root of the time since the start. Which of the following differential equations describes this relationship, where k is a positive constant?

a. df/dt= k3√t
b. df/dt= k3√f
c. d^2f/dt^2= k3√t
d. d^2f/dt^2= k3√f

Answers

Answer:

C. [tex]\frac{d^{2}f}{dt^{2}} = k\cdot \sqrt[3] {t}[/tex]

Step-by-step explanation:

Physically speaking, the acceleration is equal to the second derivative of the position of the vehicle in time. After a careful reading to the statement, we construct the following ordinary differential equation:

[tex]\frac{d^{2}f}{dt^{2}} = k\cdot \sqrt[3] {t}[/tex]

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]k[/tex] - Proportionality constant, measured in meters per second up to 7/3.

Therefore, the correct answer is C.

The differential equation that models the situation is:

[tex]\frac{d^2f}{dt^2} = k\sqrt[3]{t}[/tex]

Which is option C.

The position is the integral of the acceleration, with is the integral of the acceleration, hence, the relation between the position and the acceleration is:

[tex]\frac{d^2f}{dt^2}[/tex]

The acceleration is proportional to the cube root of the time since the start, hence:

[tex]\frac{d^2f}{dt^2} = k\sqrt[3]{t}[/tex]

In which k is the constant of proportionality.
