Answer:
The volume of cone v= 113.04 cm³.
Step-by-step explanation:
Formula used to find volume of cone is:
[tex]v= \pi * r^2 * \frac{h}{3}[/tex]
where r is the radius and h is the height of cone.
In the given question we are given:
height h= 6 cm
diameter d= 6 cm
We know radius r = d/2 = 6/2 = 3 cm
so, volume will be:
[tex]v= \pi * 6^2 * \frac{3}{3}[/tex]
[tex]v= \pi * 36 [/tex]
[tex]v=113.04[/tex]
So, the volume of cone v= 113.04 cm³ given height h= 6cm and radius r= 3cm

the value of a $3000 computer decreases about 30% each year. write a function for the computers value V(t)
How much will the computer be worth in 4 years?
Answer:
Function for given situation is : [tex]V(t)=3000(0.70)^t[/tex]
Value of computer after 4 years = $720.3.
Step-by-step explanation:
Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then we need to find about how much will the computer be worth in 4 years.
It clearly says that value decreases so that means function represents decay.
For decay we use formula:
[tex]A=P(1-r)^t[/tex]
where P=initial value = $3000,
r= rate of decrease =30% = 0.30
t= number of years
A=V(t) = future value
so the required function is [tex]V(t)=3000(1-0.30)^t[/tex]
or [tex]V(t)=3000(0.70)^t[/tex]
Now plug t=4 years to get the value of computer after 4 years.
[tex]V(4)=3000(0.70)^4[/tex]
[tex]V(4)=720.3[/tex]
Hence final answer is $720.3.
Answer:
A = $3000(0.70)^t
Step-by-step explanation:
100% - 30% = 70%. Thus, the common ratio in this exponential function is 0.70.
Use a formula with the form of the compound amount formula:
A = P(1 + r)^t, where r is the common ratio as a decimal fraction and t is the number of years.
Here, A = $3000(1 - 0.30)^t, or A = $3000(0.70)^t

Answer:
640
Step-by-step explanation:
Expanding the binomial :
r⁵ - 40r⁴ + 640r³ - 5120r² + 20480r - 32768
The coefficient of r³ is 640
Answer:
Step-by-step explanation:
Apply binomial theorem to expand (a+b)^n where a = r, b = -8 n n = 5
the r^3 term is (5!/(2!*(5-2)!)*r^3*(-8)^(5-3)
=(5*4*3*2*1/1*2*1*2*3)*r^3*(-8)^2
=640*r^3
So the coefficient is 640.
Consider a right cone with radius 2 and height 6. Its volume is V = π(2)26, or 8π units3.
If the height is changed to 3, does this have the same effect on the volume as changing the radius to 1?
If the height is now 3, then the new volume is π units3.
If the radius is now 1, then the new volume is π units3.
Therefore, changing the height to half of its original value and changing the radius to half of its original value does the volume. Halving the height of the cone the volume, while halving the radius of the cone results in the volume.
Halving the height halves the volume, but halving the radius quarters it; their effects on volume differ.
It seems there might be a typo or a mistake in your reasoning. Let's reassess the situation:
Original cone:
- Radius, [tex]\( r = 2 \)[/tex]
- Height, [tex]\( h = 6 \)[/tex]
- Volume, [tex]\( V_1 = \frac{1}{3} \pi r^2 h = \frac{1}{3} \pi (2)^2 (6) = 8\pi \)[/tex] cubic units
Now, you're considering two scenarios:
1. If the height is changed to [tex]\( h = 3 \)[/tex]:
- New volume, [tex]\( V_2 = \frac{1}{3} \pi (2)^2 (3) = 4\pi \)[/tex] cubic units
2. If the radius is changed to \( r = 1 \):
- New volume, [tex]\( V_3 = \frac{1}{3} \pi (1)^2 (6) = 2\pi \)[/tex] cubic units
Now, let's analyze the effects:
- Changing the height from 6 to 3 reduces the volume by half (from [tex]\( 8\pi \)[/tex] to [tex]\( 4\pi \)[/tex]).
- Changing the radius from 2 to 1 reduces the volume by a factor of [tex]\( \frac{1}{4} \)[/tex] (from [tex]\( 8\pi \)[/tex] to [tex]\( 2\pi \))[/tex].
So, changing the height to half of its original value reduces the volume by half, while changing the radius to half of its original value does not reduce the volume by half but rather by a quarter. Therefore, the effects are not the same.
describe how to solve the equation 1,150= 100x h for h
Step-by-step explanation:
[tex]100xh=1,150\qquad\text{divide both sides by}\ 100x\neq0\\\\\dfrac{100xh}{100x}=\dfrac{1,150}{100x}\\\\\boxed{h=\dfrac{115}{x}}[/tex]
To solve the equation \( 1,150 = 100 \times x \times h \) for \( h \), you want to isolate \( h \) on one side of the equation. Follow these steps:
**Step 1: Understand the equation**
The equation is saying that 100 times the product of \( x \) and \( h \) is equal to 1,150.
**Step 2: Isolate \( h \)**
To solve for \( h \), you need to get \( h \) by itself on one side of the equation. Right now \( h \) is being multiplied by \( 100 \times x \). To undo this, you'll divide both sides of the equation by \( 100 \times x \).
**Step 3: Perform the division**
Divide both sides of the equation by \( 100 \times x \):
\[
\frac{1,150}{100 \times x} = \frac{100 \times x \times h}{100 \times x}
\]
**Step 4: Simplify both sides**
On the right-hand side, \( 100 \times x \) in the numerator and \( 100 \times x \) in the denominator cancel each other out:
\[
\frac{1,150}{100 \times x} = h
\]
**Step 5: Result**
You are left with \( h \) by itself on one side of the equation and \( \frac{1,150}{100 \times x} \) on the other:
\[
h = \frac{1,150}{100 \times x}
\]
Now \( h \) has been solved in terms of \( x \), and you can find the value of \( h \) if you know the value of \( x \) by simply substituting that value into this equation and performing the calculation.

Find the perimeter of a square that is 3 3/4 inches on a side. 7 inches 15 inches 12 inches 30 inches
Answer:
15 inches
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of its sides. A square has 4 sides, all the same length. We can either add up the side lengths, or we can recognize that multiplication of one side's length by 4 is a useful alternative.
perimeter = 4 × (3 3/4 in)
= (4×3 +4×3/4) in
= 12 in + 3 in = 15 in

A die is tossed. Find p(less than 5/even)
Answer:6/36
Step-by-step explanation:
The probability of rolling a number less than 5 and even on a die is 1/2.
Explanation:To find the probability of rolling a number less than 5 and even, we need to determine the number of outcomes that satisfy both conditions and divide it by the total number of possible outcomes.
There are three outcomes that satisfy both conditions: {2, 4, 6}. The total number of possible outcomes is six since a die has six sides.
Therefore, the probability of rolling a number less than 5 and even is 3/6, which simplifies to 1/2.
Tania took selfies with her 8 cousins. Each cousin is in exactly 2 or 3 pictures. There are 5 cousins in each picture. How many selfies did Tania take?
Answer:
4
Step-by-step explanation:
How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )
We know that each cousin appear 2 or 3 times overall.
If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos
If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos
We know there's exactly 5 cousins per photo...
so we have to find a multiple of 5 cousins/photos that is between 16 and 24.
The only possibility is 20 cousins/photos. 20 / 5 = 4 photos.
Final answer:
Tania took 4 selfies with her cousins. Each cousin appeared in exactly 2 selfies, with some appearing a third time to account for 16 total cousin appearances divided by 5 cousins per selfie.
Explanation:
The problem presented is a combinatorial puzzle involving selfies and cousins. Since each cousin is in either 2 or 3 pictures, we can try to minimize the number of pictures by assuming each cousin is in exactly 2 pictures first. If there are 8 cousins and 5 cousins per picture, then by multiplying 8 by 2 (every cousin appears exactly 2 times), we get 16 cousin appearances in total.
Since each selfie has 5 cousins, we divide the total cousin appearances by the number of cousins per picture: 16 / 5, which results in 3.2. However, since it's not possible to have a fraction of a picture, we need at least 4 selfies to cover all appearances. Yet, this leaves us 4 extra appearances (because 4 pictures would mean 20 cousin appearances in total).
These 4 extra appearances account for the fact that some cousins appear 3 times instead of just 2. Therefore, Tania must have taken 4 selfies with her cousins to cover the 16 cousin appearances with some cousins appearing an additional third time.
A Wooden board is leaning against the house the base of the board is 10 feet from the base of the house and the base of the board forms a 35° angle with the ground what is the length of the wooden board
Answer: 12.20 feet.
Step-by-step explanation:
Observe in the figure attached that a right triangle is formed.
Then, you need to remember the identity:
[tex]cos\alpha=\frac{adjacent}{hypotenuse}[/tex]
In this case you can identify that:
[tex]adjacent=10\\hypotenuse=x[/tex]
[tex]\alpha=35\°[/tex]
Then, to find the length of the wooden board (x), you need to substitute values and solve for x.
Therefore, you get:
[tex]cos(35\°)=\frac{10}{x}\\\\(x)(cos(35\°))=10\\\\x=\frac{10}{cos(35\°)}\\\\x=12.20[/tex]
The length of the wooden board is: 12.20 feet.

Thirty six pencils are packed in three boxes. How many pencils are packed in five boxes
Each pencil box usually contains same amount of pencils. In given context the number of pencils in five boxes is 10 pencils.
How to decide the number of containment of items?Suppose that its given that 'a' boxes contains 'b' items, then, assuming that each box contains 'x' items, then
[tex]x + x + ... + x \text{ (a times)} = b\\\\x \times a = b\\\\x = \dfrac{b}{a}[/tex]
Thus, there are 'b/a' items contained in each box.
Since there are six pencils in three boxes, let there are 'x' pencils in one box, then we have:
[tex]x + x + x = 6\\3 \times x = 6\\\\\text{Dividing both sides by 3}\\\\x = \dfrac{6}{3} = 2[/tex]
Thus, there are 2 pencils in each pencil box.

Final answer:
By using proportional reasoning, if three boxes contain 36 pencils, then five boxes would contain 60 pencils.
Explanation:
If thirty-six pencils are packed in three boxes, then there are twelve pencils per box because 36 divided by 3 equals 12.
To find out how many pencils are packed in five boxes, we multiply twelve pencils (the number of pencils per box) by five boxes.
Therefore, 12 pencils/box × 5 boxes = 60 pencils in five boxes.
This is a simple proportional reasoning problem, often encountered in mathematical exercises in school.
Let f(x) = 3x + 2 and g(x) =7x + 6. Find f ·g and its domain.
Answer:
[tex]f * g = 21x ^ 2 + 32x +12[/tex]

Step-by-step explanation:
We have the functions [tex]f (x) = 3x + 2[/tex] and [tex]g (x) = 7x + 6[/tex]
We want to find f*g. Then we must multiply the function f by the function g.
Note that the function [tex]f (x) = 3x +2[/tex] is a linear function, therefore its domain is all real numbers. In the same way the function [tex]g (x) = 7x + 6[/tex] is also a linear function and its domain is all real numbers.
The multiplication of f * g will be
[tex]f * g = (3x + 2) (7x + 6)\\\\f * g = 21x ^ 2 + 18x + 14x +12\\\\f * g = 21x ^ 2 + 32x +12[/tex]
The function g(x) is a quadratic function and its domain is the intercept of the domain of f(x) with the domain of g(x), that is, all real numbers.

Which shows the correct substitution of the values a,b, and c from the equation 0=-3x^2-2x+6 into the quadratic formula ?
Answer:
a = -3
b = -2
c = 6
Step-by-step explanation:
The quadratic formula states that for an equation of the form:
[tex]ax^{2} + bx + c = 0[/tex]
The solution to that equation is:
[tex]\frac{-b±\sqrt{b^{2}-4ac}}{2a}[/tex]
In this case we have:
0=-3x^2-2x+6
Where:
a = -3
b = -2
c = 6
