from the height of a wall if a ladder 10 metre long place along the wall and its foot is 2 metre away from the wall.​

Answers

Answer 1

Answer:

height of the wall = 9.79 m

Step-by-step explanation:

This form a right angled triangle.

Hypotenuse = length of the ladder = 10 m

Base = length from foot of ladder to wall.

Altitude = height of the wall

Pythagorean's theorem,

base² + altitude² = hypotenuse²

  2² +  altitude² = 10²

4 +  altitude² = 100

      altitude² = 100 - 4

      altitude² = 96

      altitude = √96 = 9.79 m

A piece of Styrofoam has a charge of -0.004 C and is placed 3.0 m from a piece of salt with a charge of -0.003 C. How much electrostatic force produced?
And please show work of how you got the answer pls :)

Answers

Given that,

Charge q₁ = -0.004 C

Charge q₂ = -0.003 C

Distance between charges, d = 3 m

To find,

The electrostatic force between charges.

Solution,

The formula for the electrostatic force is given by :

[tex]F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 0.004 \times 0.003 }{(3)^2}\\\\=12000\ N[/tex]

So, 12000  N of electrostatic force is produced.

This question is based on the concept of electrostatic.Therefore, the electrostatic force produced is 12000 N.

Given:

Charge q₁ = -0.004 C

Charge q₂ = -0.003 C

Distance between charges, d = 3 m

We need to determined the how much electrostatic force produced.

According to the question,

By using the formula for the electrostatic force is given by :

[tex]F = k \dfrac{q_1 \; q_2}{d^2} \\\\F = \dfrac{9 \times 10^9 \times 0.004 \times 0.003 }{3^2} \\\\\bold{F= 12000 \; N} \\[/tex]

Therefore, the electrostatic force produced is 12000 N.

Washington College has many students enrolled in their engineering program. Engineering students at Washington College last year received an average of $9,600 in scholarships and grants. This year, the average is $5,184. What is the percent of change in the average amount received? Was this an increase or decrease?

Answers

Answer:

The percent of change in the average amount received was 46% and this was a decrease.

Step-by-step explanation:

You can use the following formula to calculate the percentage of change:

% of change = ((New number-Original number) / Original Number) x 100

New number= 5,184

Original number= 9,600

Now, you can replace the values in the formula:

% of change = ((5,184-9,600) / 9,600) x 100

% of change = (-4,416 / 9,600) x 100

% of change = (-0.46) x 100

% of change = -46%

According to this, the answer is that the percent of change in the average amount received was 46% and this was a decrease.

In the diagram, AGEF and AHEF are congruent. What is the value of x? A. 60 B. 41 C. 28 D. 30​

Answers

Answer: C) 28

Explanation:

The triangles are congruent, so the corresponding pieces are congruent. Specifically the angles on the right side are congruent, as shown by the tickmarks they have in common.

Set those two expressions equal to one another. Solve for x.

2(x+2) = 60

2x+4 = 60

2x = 60-4

2x = 56

x = 56/2

x = 28

The correct value of the variable x is,

⇒ x = 28

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In the diagram,

ΔGEF and ΔHEF are congruent.

Hence, We can formulate;

⇒ 2 (x + 2) = 60°

⇒ 2x + 4 = 60

⇒ 2x = 60 - 4

⇒ 2x = 56

⇒ x = 28

Thus, The correct value of the variable x is,

⇒ x = 28

Answers

Answer:

x = -1 ± √6

Step-by-step explanation:

[tex]x^{2} +2x - 5 = 0[/tex]

Lets use the quadratic formula → [tex]x = \frac{-b + \sqrt{b^{2} - 4ac} }{2a} \:or \frac{-b - \sqrt{b^{2}- 4ac } }{2a}[/tex]

So ,

[tex]x = \frac{(-2) + \sqrt{(2)^{2} - (4\times1\times-5) } }{2\times1} \:or \frac{(-2) - \sqrt{(2)^{2} - (4\times1\times-5) }}{2\times1}[/tex]

[tex]=> x = \frac{-2 + \sqrt{24} }{2} \:or \frac{-2-\sqrt{24} }{2}[/tex]

[tex]=> x = \frac{-2 + 2\sqrt{6} }{2} \:or \frac{-2 - 2\sqrt{6} }{2}[/tex]

Lets take 2 common from numerator.

[tex]=> x = \frac{2(-1 + \sqrt{6}) }{2} \:or \frac{2(-1-\sqrt{6}) }{2}[/tex]

Cancelling 2 from numerator & denominator gives

Write the rule for the linear function. Remember a function rule is written using f(x)

Answers

Answer:

The rule for the linear function will be:

[tex]f(x) = -2x+5[/tex]

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points from the table to determine the slope

(1, 3)(2, 1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:3\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)[/tex]

[tex]m=\frac{1-3}{2-1}[/tex]

[tex]m=-2[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (1, 3)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 3 = -2 (x-1)[/tex]

[tex]y-3 = -2x+2[/tex]

adding 3 to both sides

[tex]y-3+3 = -2x+2+3[/tex]

[tex]y = -2x+5[/tex]

or

[tex]f(x) = -2x+5[/tex]

Therefore, the rule for the linear function will be:

[tex]f(x) = -2x+5[/tex]

cost of the services is equal. (Write your final answer as a
decimal.)

Answers

Answer:

8.8 hours

Step-by-step explanation:

happy paws charges $21 in addition to $2.5 per hour -- we can write this as

21 + 2.5 per hour -- since the number of hours is x, this is equal to

21 + 2.5 (x)

similarly, woof watchers is

10 + 3.75 (x)

we must find when the services are equal --

21 + 2.5x = 10+3.75x

subtract 10 from both sides

11 + 2.5x = 3.75x

subtract 2.5x from both sides

11 = 1.25

divide both sides by 1.25

x = 8.8
