Answer: 1452 units^3

The required volume of the cylinder with a height of 12 units and radius of 11 units is 1452π cubic units.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

The formula for the volume of a cylinder is given as:

V = πr²h

Where V is the volume of the cylinder, r is the radius of the cylinder, and h is the height of the cylinder.

Substituting the given values, we get:

V = π(11)²(12)

= π(121)(12)

= 1452π cubic units

Therefore, the volume of the cylinder with a height of 12 units and radius of 11 units is 1452π cubic units.

Step-by-step explanation:

We are given a function

f(x) = x-5

Substitute the value of x = -11 into the function

f(-11) = -11-5

        = -16

Answer:

-16

Step-by-step explanation:

Given that,

f ( x ) = x - 5

To find the value of f ( -11 ), you have to replace x with -11 & solve it.

Let us solve it now.

f ( -11 ) = x - 5

f ( -11 ) = -11 - 5

f ( -11 ) = -16

Answer:

√53 or 7.28

Step-by-step explanation:

To find the length of the line segment from the point (4, 2) to the point (-3, 4), you can use the distance formula, which is:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the coordinates of the two points, you get:

distance = √((-3 - 4)^2 + (4 - 2)^2)

Simplifying this expression gives:

distance = √((-7)^2 + (2)^2)

Which simplifies to:

distance = √(49 + 4)

Which simplifies to:

distance = √53

So the length of the line segment from the point (4, 2) to the point (-3, 4) is approximately 7.28.

The measurement of the length of two sides and the included angle are given. Hence, using law of cosines, the approximate length of the lake is found to be 296.1 yards.

Given : b = 245 yards, c= 270 yards,

To find: The length of the lake which is the value of x

To find [tex]\angle A[/tex], we know that [tex]110^o\, and\, \angle A[/tex] lie on straight line. So

[tex]110^o + \angle A = 180^o\\\\\angle A = 180^o - 110^o = 70^o[/tex]

Using law of cosines

[tex]a^2 = b^2 +c^2 - 2bc\cdot cosA[/tex]

Plugging the values of b , c and A into the equation, we get

 [tex]a^2 =245 ^2 +270^2 - 2\times 245 \times 270 \times \cos 70^o \\[/tex]

The value of [tex]\cos 70^o[/tex] is 0.342 approximately

On substituting this in the equation, we get

a = 296.1 yards

=====================================================

Explanation:

Draw a right triangle in the quadrant Q1, which is in the northeast corner.

We're given [tex]\cos(\theta) = 3/8[/tex]. Recall that cosine is the ratio of adjacent over hypotenuse.

[tex]\cos(\text{angle}) = \text{adjacent/hypotenuse}[/tex]

This right triangle will have an adjacent side of 3 and hypotenuse of 8.

Refer to the diagram below.

Use the pythagorean theorem [tex]a^2+b^2 = c^2[/tex] to find the missing side is exactly [tex]\sqrt{55}[/tex], which is the opposite side of angle theta.

Then as one last step, we would say:

[tex]\sin(\text{angle}) = \text{opposite/hypotenuse}\\\\\\\sin(\theta) = \frac{\sqrt{55}}{8}[/tex]

--------------

A very similar approach is to use the pythagorean trig identity

[tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex]

Solving for sine gets us

[tex]\sin(\theta)=\sqrt{1-\cos^2(\theta) }[/tex]

Sine is positive in Q1.

Then plug in [tex]\cos(\theta) = 3/8[/tex] and simplify. You should get the answer mentioned above.

The amount invested at 8% and 6% is 1000 and 1900 respectively.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, The person invested $2900 in two mutual funds and the total profit is $194.

Let the amount invested at 8% is x, then the amount invested at 6% is:

2900-x

Since the total profit is $194, it follows:
8% of x + 6% of (2900 - x) = 194

8x/100 + 6(2900 - x)/100 = 194

8x + 17400 - 6x = 19400

2x = 19400 - 17400

2x = 2000

x = 1000

The amount invested at 6% is:
2900 - 1000

= 1900

Hence, the amount invested at 8% and 6% is 1000 and 1900 respectively.

The linear equation that is modeled by the table is:

y = 2x + 1

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

Here we can use the first two points on the table (-3, -5) and (-1, -1), we will get the slope:

a = (-1 + 5)/(-1 + 3)

a = 4/2 = 2

Then the line is something like:

y = 2x + b

To find the value of b we can use one of the points (-3, -5), replacing these values we will get:

Step-by-step explanation:

Sine and cosine are the fundamental trigonometric functions associated to the sides of a right triangle and tangent is a derivate trigonometric function.

Let be a right triangle, whose features are introduced in the figure attached below. The side with measure y is the side opposite to the angle θ, whereas the side with measure x is the side adjacent to the angle θ. The side with measure r represents the hypotenuse of the right triangle, which can be found by means of Pythagorean theorem:

r = √(x² + y²)

Trigonometric functions are trascendent functions that relates two sides of the right triangle. There are two fundamental trigonometric functions and four derivate trigonometric functions:

Fundamental

sin θ = y / r = (Opposite side) / (Hypotenuse)

cos θ = x / r = (Adjacent side) / (Hypotenuse)

Derivate

tan θ = sin θ / cos θ = y / x = (Opposite side) / (Adjacent side)

cot θ = 1 / tan θ = cos θ / sin θ = x / y = (Adjacent side) / (Opposite side)

sec θ = 1 / cos θ = r / x = (Hypotenuse) / (Adjacent side)

csc θ = 1 / sin θ = r / y = (Hypotenuse) / (Opposite side)

The question is an illustration of equation of circles.

The equation of the dartboard circle is:  [tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]

Brian's dart lands on the dartboard because D = 11.5 feet , 5 feet is within the circumference of the dartboard.

Given that,

h = 5 feet 8 inches ---- the height at which the dartboard was hung

d = 18 inches in diameter ---- the diameter of the dartboard

B = 12 feet --- the bull's eye

D = 11.5 feet , 5 feet --- Brian's dart

Equation of the circle

First, we convert all units to feet

This is done by dividing inches units by 12

h = 5 feet 8 inches

h = 5 ft + 8/12 ft

h = 5 ft + 2/3 ft

Take LCM

h = [tex]\frac{15+2}{3}[/tex] ft

h = [tex]\frac{17}{3}[/tex] ft

d = 18 inches

d = [tex]\frac{18}{12}[/tex] ft

d = [tex]\frac{3}{2}[/tex] ft

Divide by 2 to calculate radius

r = [tex]\frac{3}{2*2}[/tex] ft

r = [tex]\frac{3}{4}[/tex] ft

To find the equation of a circle when you know the radius and centre, use the formula as [tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex] , where represents the centre of the circle, and is the radius.

The equation of the circle is represented as:

[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]

In this case:

a = B = 12 feet -- the distance between the bull's eye and the wall

b = h = [tex]\frac{17}{3}[/tex] ft  ---- the height at which the dartboard was hung

So, we have:

[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]

[tex](x-12)^{2} +(y-\frac{17}{3}) ^{2} = (\frac{3}{4}) ^{2}[/tex]

Evaluate the exponents

[tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]

Hence, the equation of the circle is:

[tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]

What is substitution method?

The algebraic technique for resolving multiple linear equations at once is called the substitution method. As the name implies, this method involves substituting a variable's value from one equation into another. In this manner, a pair of linear equations are combined into a single, simple linear equation with just one variable.

Assume that x number of cups that ordered by Aunt Emily.

Given that, Clarksville Bakery charges $3 for each cupcake, plus $50 for the large cake.

Therefore, the cost of x cupcake is 50 + 3x.

y = 50 + 3x

Also, Sebastian's Sweet Shoppe charges $34 for the large cake and $4 for each cupcake.

Therefore, the cost of x cupcake is 34 + 4x.

y = 34 + 4x

The system of equations is

y = 50 + 3x  ....(i)

y = 34 + 4x  ...(ii)

To find the number of cupcakes that Aunt Emily orders, use substitution method to solve the system of equation.

Substitute y = 50 + 3x in equation (ii)

50 + 3x = 34 + 4x

Subtract 3x from both sides:
