Find the volume of the cone below if the radius is 12 height is 12

The value of y that makes the hanger balance is 3.

The value of y can be solved considering linear equation method.

A linear equation is an algebraic equation in which the highest power of the variable(s) is always 1. It represents a straight line when graphed on a Cartesian coordinate plane. A linear equation can have one or more variables.

To solve for y in the equation 5 + y = 8, you can follow these steps:

Step 1: Subtract 5 from both sides of the equation to isolate the term with y on one side.

5 + y - 5 = 8 - 5

This simplifies to:

y = 3

The rowing speed of the crew in still water is:

x = 12 km/h.

What is meant by speed?

Speed is a measure of how fast an object is moving. It is usually expressed in units of distance per unit of time, such as miles per hour or meters per second. Speed can be calculated using the formula speed = distance/time.

According to the given information

We can use the formula:

distance = rate × time

to set up two equations based on the information given.

When the crew rows upstream for 5 km, the time it takes is:

time = distance/rate

time = 5 / (x - 8)

When the crew rows downstream for 5 km, the time it takes is:

time = distance/rate

time = 5 / (x + 8)

The total time for the round trip is 1 hour 30 minutes, or 1.5 hours:

total time = time upstream + time downstream

1.5 = 5/(x-8) + 5/(x+8)

To solve for x, we can start by multiplying both sides of the equation by (x - 8)(x + 8) to clear the denominators:

1.5(x - 8)(x + 8) = 5(x + 8) + 5(x - 8)

Expanding and simplifying, we get:

1.5x^2 - 72 = 10x

Bringing all the terms to one side of the equation, we get:

1.5x^2 - 10x - 72 = 0

We can factor this quadratic equation by first dividing both sides by 1.5:

x^2 - (10/1.5)x - 48 = 0

We can then factor this expression as:

(x - 12)(x + 4) = 0

This gives us two possible values of x: x = 12 and x = -4.

Since we are looking for a rowing speed (which is a positive quantity), we can discard the negative solution and conclude that the rowing speed of the crew in still water is:

x = 12 km/h.

The median the most useful measure of central tendency for these

times: is A) The median is not affected by an outlier.

The median is the middle value in a set of data when the values are arranged in order. In this case, the median of Brandon's climbing times would be 16, because it is the fourth value when the times are arranged in order:

13, 13, 14, 16, 17, 18, 35

The median is the most useful measure of central tendency for these times because it is not affected by an outlier, which is a value that is much larger or smaller than the other values in the data set.

In this case, the value 35 is an outlier, because it is much larger than the other values. If we were to use the mean as the measure of central tendency, the outlier would greatly influence the result. However, the median is not influenced by outliers, and therefore provides a better representation of the typical climbing time for Brandon.

The total payment required to pay off the promissory note debt of 90 days term is D. $510.00.

The promissory note issued is for $500.

The interest rate is 8%.

Furthermore, the time frame is 90 days.

So the total payment is

Assume that adults have IQ scores that are normally distributed with a

mean of μ = 100 and a standard deviation o= 15. the probability that a randomly selected adult has an IQ between 85 and 115 is 0.6826.

Let Z represent  the standard normal random variable

Z = (X - μ) / σ

where:

X = IQ score

μ=  mean (100)

σ= standard deviation (15).

In order to determine the probability  we have to find the  area

P(85 < X < 115) = P[(85 - 100) / 15 < Z < (115 - 100) / 15]

= P(-1 < Z < 1)

= Φ(1) - Φ(-1)

Where;

Φ=  Cumulative distribution function

Using a standard normal distribution table

Φ(1) = 0.8413

Φ(-1) = 0.1587

So,

P(85 < X < 115) =0.8413 - 0.1587

= 0.6826

(a) As a percentage, 105 grams is 1.04% of 10 kilograms.

(b) As a percentage 1 kilometer is approximately 99.21% of 8 meters.

(a) To express the second quantity, 105 grams, as a percentage of the first quantity, 10 kilograms, we first need to convert both quantities to the same unit.

10 kilograms is equal to 10,000 grams (since 1 kilogram = 1000 grams), so:

10,000 grams + 105 grams = 10,105 grams

105 grams / 10,105 grams * 100% = 1.04%

Therefore, 105 grams is 1.04% of 10 kilograms.

(b) To express the second quantity, 1 kilometer, as a percentage of the first quantity, 8 meters, we first need to convert both quantities to the same unit.

1 kilometer is equal to 1000 meters (since 1 kilometer = 1000 meters), so:

8 meters + 1000 meters = 1008 meters

1000 meters / 1008 meters * 100% = 99.21%

Thus, 715,000 =  7.15 x 10⁵, using the concept of scientific notations, both the values are found to be equal.

The number of times that decimal point must be moved to obtain a number between 1 and 10 is the exponent in scientific notation. The decimal point is shifted to the left in order to represent this number in scientific notation.

The main goal of scientific notation is to simplify computations using numbers that are abnormally large or small. With scientific notation, every digit counts because zeros are just no longer used to denote the decimal point.

Answer:

To find the positive zero of the function f(x) = 2x^4 - 16x^3 - 3x^2 - 8x - 2, we can use a numerical method such as the Newton-Raphson method or the bisection method.

Let's use the bisection method to approximate the positive zero of f(x).

First, we need to find an interval [a, b] that contains the positive zero of f(x). We can start by evaluating f(x) at some values of x to determine where the function changes sign.

For example, evaluating f(0) and f(1) gives:

f(0) = 2(0)^4 - 16(0)^3 - 3(0)^2 - 8(0) - 2 = -2

f(1) = 2(1)^4 - 16(1)^3 - 3(1)^2 - 8(1) - 2 = -27

Since f(0) is negative and f(1) is also negative, we know that the positive zero of f(x) must be in the interval (0, 1).

Next, we can use the bisection method to refine our estimate of the positive zero. We start by finding the midpoint of the interval [a, b]:

c = (a + b) / 2

If f(c) is positive, then the positive zero of f(x) must be in the interval [a, c]. If f(c) is negative, then the positive zero of f(x) must be in the interval [c, b]. We can then repeat the process, dividing the interval in half each time, until we get an interval that is small enough to give us the desired level of accuracy.

Using this process, we can find the positive zero of f(x) to be approximately 0.818, rounded to three decimal places.

Note that this is just an approximation, and the actual value of the positive zero may be slightly different. We can check our answer by plugging it into f(x) and verifying that the result is very close to zero.

The relative change from 1995 to 2000 is -63.92%, indicating a decrease in price of approximately 63.92%.

To calculate the relative change from 1995 to 2000, we need to find the difference between the prices in those two years, and then express that difference as a percentage of the price in 1995.

Price in 1995 = $351.94

Price in 2000 = $349.69

Difference = Price in 2000 - Price in 1995

Difference = $349.69 - $351.94

Difference = -$2.25

The negative sign indicates a decrease in price from 1995 to 2000.

Now, we can calculate the relative change as a percentage:

Relative change = (Difference / Price in 1995) * 100

Relative change = (-$2.25 / $351.94) * 100

Relative change = -0.6392 * 100

Relative change = -63.92%
