Jake has a teepee that is cone shaped it has a height of 9 feet and a diameter of 8 feet find the volume of the teepee in terms of Pi.

Answers

The formula is:
V = π(r^2)h/3
Since this problem gives you the diameter and not the radius, I would take half of the diameter because a radius is half of a diameter.
The half of 8 is 4, so the radius is 4
V = π(4^2)(9/3)
V = π(4^2)(3)
V = π(16)(3)
V is about 150.8

What is the modulus of 5 - 3i

Answers

Hello!

The above expression exemplifies a “complex number.” A complex number takes the following form:

a + bi

In this case, A is equal to (5) while B is equal to (-3). To find the modulus of a complex number, we will need to use the following formula (let “x” represent the modulus):

x = √(a² + b²)

Insert any known values into the formula above:

x = √((5)² + (-3)²)

Simplify the right side of the equation:

x = √(25 + 9)
x = √34

We have now proven that the modulus is equal to √34.

I hope this helps!

Final answer:

The modulus of the complex number 5 - 3i is found using the Pythagorean theorem and comes out to be square root of 34.

Explanation:

The modulus of a complex number, such as 5 - 3i, is the distance from the origin to the point representing the complex number in the complex plane. We calculate it by using the Pythagorean theorem. The modulus of the complex number 5-3i is given by √((Re z)² + (Im z)²) = √((5)² + (-3)²) = √(25 + 9) = √34, where Re z represents the real part of the complex number, and Im z represents the imaginary part. So, the modulus of the complex number 5 - 3i is √34.

if f(x)=8x+6, what is f(-1)

Answers

If I remember correctly this is how you solve it.

f(x)=8x+6
f(-1)=8(-1)+6
f(-1)=-8+6
f(-1)= -2

f(x) = 8x + 6

To find f(-1), substitute x = -1 :

f(-1) = 8(-1) + 6 = -8 + 6 = -2

Answer: f(-1) = -2

factorise 36n(squared) divide by 25 minus 1

Answers

Answer:

[tex]( \frac{36n^{2} }{25} - 1) [/tex] factors to become [tex]( \frac{6}{5}n - 1)( \frac{6}{5}n + 1) [/tex]

Explanation:
The binomial [tex]( \frac{36n^{2} }{25} - 1) [/tex] is what is called a difference of two squares which can be identified by the equation being in the form (a² - b²) where both terms can be square-rooted.

Because the equation is a difference of two squares, its factors will be in the form: (a - b)(a + b).

With a² = [tex]\frac{36n^2}{25}[/tex] and b² = 1, we can find the square root of both and plug them into the above factor form.

√(36n² / 25) = 6n/5
√1 = 1

So the factors are [tex](\frac{6}{5}n -1)(\frac{6}{5}n +1)[/tex]

Choosing seven numbers that match seven randomly selected balls when the balls are numbered 1 through 32?

Answers

Total numbers = 32
We are to select 7 numbers at a time. Selecting 7 numbers from a group of 32 is a combination problem. It is similar to making combination of 32 objects taken 7 at a time.

So total possible combinations of 7 numbers can be calculated as 32C7.

32C7 = 3365856

Only 1 combination can match the randomly selected combination.

So, the probability that he combination of 7 numbers will match the seven randomly selected balls = [tex] \frac{1}{3365856} [/tex]

a circle has an area of 81 3.14 units . what is the diameter in terms of 3.14a circle has an area of 81 Pi square units what is the diameter of the circle

Answers

You have posted 2 separate questions here. Please, next time, separate them with a blank line:

A circle has an area of 81 3.14 units . what is the diameter in terms of 3.14?

I'd prefer you write this as
"A circle has an area of 81 pi units . what is the diameter in terms of pi?

Area of a circle = A = pi*r^2. Note that r= diameter / 2. Here, the area is 81 pi square units, or 9^2 * pi square units, which means that the radius is 9 units. The diameter is then 2(9 units) = 18 units.

Your second question, separated from the first, is:

"a circle has an area of 81 Pi square units what is the diameter of the circle?"

Use the following formula or formulas: d = 2*r; A = pi*r^2; A = pi*(d/2)^2. Find r first, and then find d.

Answer:

18 units

Step-by-step explanation:

[tex]\pi r^2=81\pi[/tex]

Solve for [tex]r[/tex]:

[tex]\pi r^2=81\pi \\r^2=81\\r=9[/tex]

Knowing diameter is 2*r, we can apply the formula to find diameter

[tex]d=2*r\\d=2*9\\d=18[/tex]

Question 2 Unsaved Cat is 5 less than twice Dog's age. Cat is 11 years old. Find Dog's age.

Answers

The dog is 8 years old because If you take 8 and multiply it by 2 you get 16 and then you subtract 5 and you get 11 years old or the cats age

Let the dog's age be called x.

From the given statement, the following equation can be framed

Cat's age = 2*x -5

We are given to know that Cat's age is 11 years

So, we have:

11 = 2x -5

2x = 16

x = 16/2

x = 8

Dog's age = 8 years

The base of a triangular prism is an isosceles right triangle with a hypotenuse of
√50 centimeters. The height of the prism is 8 centimeters. Find the surface area of the triangular prism. Round your answer to the nearest tenth.

Answers

Are sure that is right

SA= Lateral Area + Area (of base)

Lateral area = perimeter of base x height

An isosceles triangle has two congruent base segments. The hypotenuse of an isosceles right triangle is (length of base segment) x (the square root of 2). I did the math for you (shown above) to get 5 as a base.

So 5 + 5 + square root of 50 is your perimeter

Multiply the perimeter times your height (8) and you get the lateral area.

Add your lateral area to the base area (triangle = 1/2 bh)

LA = 136.568...
Area of Triangle base = 12.5

Surface area = 149.068... square cm

Write an Inequality for the following situation

No more than 8 books are in your bag

Answers

No more means less or equal.
if number of books is x,
then
x≤8.

It says "No more than 8 books are in your bag". Here "Not more than" a specific number would be a set of all values that are "less than or equal" to given number.

So let's consider 'n' represents the number of books in the bag and we know this number can not be a negative value i.e. n is "greater than or equal" to 0.

Also n is "less than or equal" to 8 as given in the question.

Hence, the inequality would be 0 ≤ n ≤ 8.

Samantha measured two of the angles in PQR and found that they had measures of 65° and 70°. Then, she measured two of the angles in XYZ and found that they had measures of 65° and 45°. What statement best describes the two triangles?

Answers

The two triangles are similar.

The angles of a triangle sum to 180°. Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45

We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70

Any two triangles that have all 3 angles congruent is similar by AAA.

Given: a = 640, A = 70°, B = 52° in triangle ABC ; find b. Round answers to the nearest whole number

Answers

Answer: 537

Step-by-step explanation:

Given: a = 640 A =70° B =52°

Whenever two angles and one side of a triangle is given, we can always use the sine formular to find the other side

Using the sine formula;

sin A / a = sin B /b

sin70° / 640 = sin 52° / b

cross multiply

bsin70° = 640sin52°

To get b, we divide bothside by

sin 70°

b = 640sin52° / sin 70°

b = 504. 327 / sin70°

b = 536. 693

b = 537 to the nearest whole number

Answers

y=mx+b

where in this case

59(F−32)

59F−59(32)

You can see the slope of the graph is

59, which means that for an increase of 1 degree Fahrenheit, the increase is 59 of 1 degree Celsius.

59(F)

59(1)=59

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of

95 degrees Fahrenheit.

59(F)

(F)=

Since

95 = 1.8, statement II is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of

59 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

59(F)

59(59)

2581(whichis≠1)

An increase of

59 degree Fahrenheit leads to an increase of 2581, not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.
