A Ferris wheel has a radius of 50 feet, and its center is 60 feet off the ground. How many points on the Ferris wheel are: 30 feet off the ground?

Answer:

1274.7 cubic meters

Step-by-step explanation:

Because the equation to find volume of a cone is V = πr²(h/3), you would have to plug in your values which are h = 5.2m, and r = 15.3m. Once you do the math you will get 1274.72 cubic meters, or 1274.7 when rounded to the nearest tenth.

Answer:

Because you need to be able to have a common demoniator in order to cancel out certain steps. For instance you cannot add or subtract fractions without having a common denominator.

Answer:

r = -1/5

Step-by-step explanation:

5(r - 10) = -51

Distribute

5r - 50 = -51

Add 50 to each side

5r-50+50 = -51+50

5r = -1

Divide each side by 5

5r/5 = -1/5

r = -1/5

Answer:

128 m^3

Step-by-step explanation:

The volume of the rectangular prism base is (8 m)(8 m)(10 m), or 640 m^3.

The triangular 'cap' has a base area of 64 m^2 and a height of 6 m, and thus a volume of (1/3)(64 m^2)(6 m) = 128 m^3

Answer:

The radius is 4 units, and the equation of the circle is:

(x - 3)^2 + (y + 5)^2 = 16

Step-by-step explanation:

A circle centered at the point (a, b) and with a radius R, is written as:

(x - a)^2 + (y - b)^2 = R^2

In the image, we can see that a segment that cuts the circle in two halves is the segment between the points:

(-1, -5) and (7, - 5)

The distance between these points is the diameter of the circle.

Remember that the distance between two points (x₁, y₁) and (x₂, y₂) is:

D = √( (x₂ - x₁)^2 + (y₂ - y₁)^2)

Then in this case, the distance between the known points is:

D = √( (7 - (-1))^2 + (-5 - (-5))^2)

D = √( 8^2) = 8

The diameter of the circle is 8

Then the radius is:

R = 8/2 = 4

the radius is 4.

Now, to find the center of the circle we just need to go to any of the two extremes of the interval and count 4 units towards the center of the circle, this is:

(-1 + 4, -5) = (3, -5)

or

(7 - 4, -5) = (3, -5)

Then the center of the circle is the point (3, -5) and the radius is R = 4

The equation of the circle is:

(x - 3)^2 + (y - (-5))^2 = 4^2

(x - 3)^2 + (y + 5)^2 = 16

Answer:

[tex] \large \boxed{ \boxed{ \tt{g(4) = - \frac{16}{3} \longrightarrow \: \: Improper \: \: Fraction \: \: }}} \\ \large \boxed{ \boxed{ \tt{g(4) = - 5 \frac{1}{3} \longrightarrow \: \: Mixed \: \: Fraction \: \: }}}[/tex]

Step-by-step explanation:

We are given the function below:

[tex] \large{g(x) = \frac{4x}{3x - 15} }[/tex]

To find g(4), we simply substitute x = 4 in the equation.

[tex] \large{g(4) = \frac{4(4)}{3(4) - 15} }[/tex]

Then evaluate the value and simplify in the simplest form.

[tex] \large{g(4) = \frac{16}{12 - 15} } \\ \large{g(4) = \frac{16}{ - 3} } \\ \large{g(4) = - \frac{16}{3} }[/tex]

Therefore, the value of g(4) is - 16/3

Mixed Fraction Form

[tex] \large{g(4) = - 5 \frac{1}{3} }[/tex]

Answer:

D

Step-by-step explanation:

Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle. Therefore, option D is the correct answer.

An acute angle is an angle that is less than 90°, and these angles can be measured using a protractor.

Triangles can be classified on the basis of angles and sides. An acute triangle is one that is classified on the basis of the measurement of angles. If all the interior angles of a triangle are less than 90°, then the triangle is said to be an acute triangle.

In equilateral triangle all three angles are equal, that is 60°.

Therefore, option D is the correct answer.

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

Explanation:

f(x) = x^3 - 2x + 3

f ' (x) = 3x^2 - 2 ..... apply the power rule

f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point

f ' (1) = 1

If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value.

Now apply point slope form to find the equation of the tangent line

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

y = x - 1 + 2

y = x + 1   is the equation of the tangent line.

Answer:

√65 ft = 8.1 ft

Step-by-step explanation:

We solve using Pythagoras Theorem

c² = a² + b²

c = √a² + b²

Where c = Length of the Hypotenuse

a = 4ft , b = 7ft

Hence

c = √4² + 7²

c = √16 + 49

c = √(65)

c = 8.0622577483 ft

Approximately = 8.1 ft

Therefore, the length of the hypotenuse is √65 ft = 8.1 ft

Cos A = x/z

Step-by-step explanation:

You need to memorize the definitions of all the trig functions and then these types of problems become easy!   OK?

Cos = adjacent side/hypotenuse

Cos A = x/z

Answer:

Step-by-step explanation:

Use a^2 + b^2 = c^2 to get the third side.

a = 12

b = ?

c = 37

a^2 + b^2 = c^2

144 + b^2 = 37^2

144 + b^2 = 1369       Subtract 144 from both sides.

-144              -144

b^2 = 1225                Take the square root of both sides

sqrt(b^2) = sqrt(1225)

b = 35

Perimeter = a + b + c

Perimeter = 12 + 35 + 37

Perimeter = 84

Answer: about 14

Work Shown:

Add up the values in the table:

170+135+150+145 = 600

There are 600 orders in total. Of those 600, we have 135+145 = 280 that are for lemonade or for orange juice. This means roughly 280/600 = 0.4667 of all the drinks are either lemonade or orange juice.

Assuming this ratio keeps up, we can multiply 0.4667 with 30 to get

30*0.4667 = 14.001 which rounds to 14

This represents the estimated number of drinks in the next 30 orders that are either lemonade or orange juice.
