how fast is the top of the ladder moving down the wall when its base is 12 feet and 35 feet from the wall?

Answers

Answer 1

The top of ladder is moving down the wall at the rate of 1.375 ft/sec .

In the given question we have to find how fast is the top of the ladder moving down the wall.

Let the distance between floor and top point of ladder = x

the distance between wall and bottom point of ladder = y

Using Pythagorean law,

x^2+y^2 = (12)^2

x^2+y^2 = 144.....................(1)

Differentiating with respect to t:

d/dt (x^2+y^2) = d/dt (144)

2xdx/dt+2ydy/dt = 0

Given that

dy/dt = 3

So 2xdx/dt+2y*3 = 0

2xdx/dt+6y= 0

dx/dt = - 3y/x

Using (1):

dx/dt = -3y/√144-y^2  

When y = 5:

dx/dt = -3(5)/√144-(5)^2

dx/dt = -15/√144-25

dx/dt = -15/√119

dx/dt = -15/10.91

dx/dt = -1.375

So the top of ladder is moving down the wall at the rate of 1.375 ft/sec .

Find the perimeter of the triangle XYZ with verticles X (1, 3) , Y(-4, -1) and Z(4, -1). Round your answer to two decimal places

Answers

Answer:

The perimeter is approximately 6.40.

Step-by-step explanation:

To find the perimeter of a triangle with vertices X (1, 3), Y (-4, -1), and Z (4, -1), we can first find the distance between each pair of points using the distance formula.The distance between points X and Y is:

$d(X,Y) = \sqrt{((1 - (-4))^2 + (3 - (-1))^2)} = \sqrt{25 + 16} = \sqrt{41}$

The distance between points Y and Z is:$d(Y,Z) =

\sqrt{((-4 - 4)^2 + ((-1) - (-1))^2)} = \sqrt{0 + 0} = 0$

The distance between points X and Z is:

$d(X,Z) = \sqrt{((1 - 4)^2 + (3 - (-1))^2)} = \sqrt{9 + 16} = \sqrt{25}$

We can then find the perimeter of the triangle by adding up the lengths of the sides. In this case, the perimeter is $d(X,Y) + d(Y,Z) + d(X,Z) = \sqrt{41} + 0 + \sqrt{25} = \sqrt{41} + \sqrt{25} = 6.40\ldots$.

Rounded to two decimal places, the perimeter is approximately 6.40.

The other has a volume of 196.25 cubic centimeters. What is the radius of each cylinder? (Use 3.14 as an approximation of pi.)

Answers

The radii of the cylinders found using the formular for the volume of a cylinder, and the 2009.6 cubic centimeter and 196.25 cubic centimeter volumes of the cylinders, indicates;

The radius of the 2009.6 cm³ cylinder is 8 centimeters

The radius of the 196.25 cm³ cylinder is 2.5 centimeters

What is a cylinder?

A cylinder is a solid that has three dimensions, consisting of two circular, parallel bases that enclose a curved pipe like surface in between.

The volume of one cylinder = 2009.6 cubic centimeters

The volume of the other cylinder = 196.25 cubic centimeters

The height of each cylinder, h = 10 centimeters

The formula for finding the volume of a cylinder is; V = π·r²·h

Where;

r = The radius of the cylinder

h = The height of the cylinder

The formula for finding the volume of a cylinder indicates;

r² = V/(π·h)

r = √(V/(π·h))

The radius of the cylinder of volume 2009.6 cubic centimeters, r₁ is therefore;

r = √(2009.6/(3.14 × 10) = 8

The radius of the 2009.6 cubic centimeters volume cylinder is r₁ = 8 cm

The radius, of the 196.25 cubic centimeters cylinder, r₂, is therefore;

r₂ = √(196.25/(3.14×10)) = 2.5

The radius of the 196.25 cubic centimeter volume cylinder, r₂ = 2.5 cm

To find the maximum, input the vertices (0,8), (5,4) and (9,0) into the objective function (P = 3x + 2y) to determine which vertex obtains the maximum value.

Note: (5,4) is not a vertex.

(0,8) :

P = 3*0 + 2*8

(5,4):
P = 3*5 + 2*4

Answers

The quadratic equation with the given x-intercepts and that passes through the point (1, 192) is the one in option D.

y = -8x^2 -64x + 264

What is the quadratic equation?

If a quadratic equation has x-intercepts x₁ and x₂ and a leading coefficient a, we can write the quadratic equation as:

y = a*(x - x₁)*(x - x₂)

Here we know that the x-intercepts are -11 and 3, replacing that in the equation above we will get:

y = a*(x + 11)*(x - 3)

We also know that the line passes through the point (1, 192), replacing the values in the quadratic equation we will get:

192 = a*(1 + 11)*(1 - 3)

192 = a*12*-2

192 = -24*a

192/-24 = a

-8 = a

So the quadratic equation is:

y = -8*(x + 11)*(x - 3)

Expanding this, we will get:

y = -8x^2 -64x + 264

So the correct option is D.

The total cost of the meal plus tip and tax was more than 122% of the cost of the bill.

What is percent?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

Indigo goes out to lunch.

The bill, before tax and tip, was $10.85.

A sales tax of 3% was added on.

Indigo tipped 18% on the amount after the sales tax was added.

The amount after adding sales tax is,

$10.85 x 3% = 0.3255

⇒ $10.85 + 0.3255 = $11.1755

Now to find the amount after tipped 18% on the amount after the sales tax was added.

$11.1755 x 18% = 2.01159

⇒ $11.1755 + 2.01159 = $13.18709

Hence, the amount  after tipped 18% on the amount after the sales tax was added is $13.18709.

Let x be the percent of more than the cost of the bill of $13.18709.

[tex]\frac{10.85(x)}{100} = 13.18709\\ x = \frac{100 (13.18709)}{10.85}\\ x = 121.54[/tex]

Answers

Answer:

  960.50 feet

Step-by-step explanation:

You want to know the height of a balloon if it is 1424 feet horizontally from a landmark at an angle of depression of 34°.

Tangent

The geometry of the problem can be modeled as a right triangle with a base angle of 34°, the adjacent leg 1424 feet, and the opposite leg being the height of the balloon. The tangent relation tells us ...

  Tan = Opposite/Adjacent

  Opposite = Adjacent·Tan

  height = (1424 feet)·tan(34°) ≈ 960.50 feet

The balloon's vertical distance from the ground is 960.50 feet.

Additional comment

If the angle is measured to the nearest degree, then the height of the balloon is somewhere between 943 feet and 979 feet. The only purpose served by reporting the distance to the nearest 0.01 foot is to see if you can use your calculator correctly.

To make that precision for the height meaningful, the angle would need to be measured with an error less than 0.00014°, about 1/2 arc-second. This is better resolution than the best surveying instruments offer, by a factor of about 30.

  RQ² = PQ² +PR²

  RQ = √((3.6×10⁶)² +(1.6×10⁷)²) = 1.64×10⁷ . . . . . use numbers, take the root

The distance between planets Q and R is 1.64×10⁷ km.

Additional comment

The "standard form" of a number is different by location. In the US, it is written with the decimal point to the right of the units digit. In other places, "standard form" has the decimal point to the right of the most-significant digit, and a power of ten as a multiplier.

You may recognize the ratio of the given numbers is 9:40, telling you these lengths are a multiple of the {9, 40, 41} Pythagorean triple. That is, the distance RQ is 41/40 times the distance RP.

Any spreadsheet or scientific or graphing calculator can do the necessary arithmetic using the numbers in "scientific notation" format. Spreadsheets, in particular, use E() to signify ×10^().

Carson earns $113.75 for 7 hours of work. If he makes a constant hourly wage, which table represents the relationship between the number of hours he works and his total earnings?

Answers

The constant amount that Carson makes every hour is $16.25.

How to illustrate the relationship?

It is important to note that this question has to do with a proportional relationship. Since Carson earns $113.75 for 7 hours of work and he makes a constant hourly wage.

The amount that he makes per hour will be:

= Amount / Number of hours

= $113.75 / 7

= $16.25

Therefore the constant amount he makes every hour is $16.25.

Solve for x them find the measure of the angle given...can someone please help me

Answers

The solution for the angle x in the figure is 130 degrees

How to determine the solution for x?

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

The transversal and the parallel line

By the theorem of vertical angles, we have the following equation

x = 5y

Also, we have the following equation

x = 2y - 78 --- by the theorem of corresponding angles

Substitute x = 2y - 78  in x = 5y

So, we have the following representation

5y = 2y - 78

Evaluate the like terms

3y = 78

Divide both sides by 3

y = 26

Substitute y = 26 in x = 5y

x = 5 * 26

Evaluate

x = 130

Hence, the value of x is 130

Given f(x) = 6x − 8 and g(x) = −5x + 2, what is (f − g)(x)?

Answers

The expression which represents the composite function (f - g) (x) as required in the task content is; 11x - 10.

Which expression represents the composite function; (f - g) (x)?

It follows from the task content that the expression which represents the composite function (f - g) (x) as required in the task content be determined.

Since the given functions are;

f(x) = 6x − 8 and g(x) = −5x + 2

The composite function; (f - g) (g) is equivalent to;

f (x) - g (x)

Therefore, we have;

(f - g) (x) = 6x - 8 - (-5x + 2)

(f - g) (x) = 6x + 5x - 8 -2

(f - g) (x) = 11x - 10.

On this note, the required expression which represents (f - g) (x) is; 11x - 10.

Write the equation for a line that passes through the given points Write the equation in slope- intercept form
. (6,-4), (6,5)

Answers

The equation of the line, in slope-intercept form,  that passes through the given points, (6,-4) and (6,5) is: x = 6.

How to Write the Equation of a Vertical Line?

An vertical line can be written in slope-intercept form as x = a, because the line has no y-intercept and the change in x values in the slope formula is equal to zero.

The value of a in the equation is the point on the x-axis where the vertical line intercept, irrespective of the change in y-values up the line.

Given the line goes through the points, (6, -4) and (6, 5), it means the line is a horizontal line because they both have the same x-value, 6.

Therefore, the value of a is 6. The equation of the line would be x = 6.
