The figure below is made up of 1 centimeters cubes, What is the volume of the figure?

Answer:

B. y = (x+1)(x-3)

Step-by-step explanation:

Bbecause when y intersect the x axis, y = 0

so (x+1)(x-3) = 0, which we get x = -1 and x = 3

As shown in the graph this is true, because the function does indeed also intersect with the x axis at x = -1 and x = 3 as well.

Answer:

-8

Step-by-step explanation:

(x-3y=136) + (18x+3y=288) We collect both processes to make y's disappear

19x=-152

x=-8

Step-by-step explanation:

a. 9 + 4x = 6x + 17

4x - 6x = 17 - 9

-2x = 8

x = -4

b. 4x - 9 = 6x + 17

4x - 6x = 17 + 9

-2x = 26

x = -13

c. 9 - 4x = 6x + 17

9 - 17 = 6x + 4x

-8 = 10x

x = -8/10

d. 4x + 9 = 6x - 17

4x - 6x = -17 - 9

-2x = -26

x = 13

a) The amount of water in the pool after 2 hours can be calculated using the equation.

Water in pool = 10L/hour × 2 hours = 20L.

b) The pool will be 80L when the equation is satisfied: 80L = 10L/hour × Time.

Solving for Time, we find Time = 8 hours.

c) Part b) is linear.

a) To calculate the amount of water in the pool after 2 hours, we can use the equation:

Water in pool = Water filling rate × Time

Since the pool gets filled up with 10L of water per hour, we can substitute the values:

Water in pool = 10 L/hour × 2 hours = 20L

Therefore, after 2 hours, there will be 20 liters of water in the pool.

b) To determine the number of hours it takes for the pool to reach 80 liters, we can set up the equation:

Water in pool = Water filling rate × Time

We want the water in the pool to be 80 liters, so the equation becomes:

80L = 10 L/hour × Time

Dividing both sides by 10 L/hour, we get:

Time = 80L / 10 L/hour = 8 hours

Therefore, it will take 8 hours for the pool to contain 80 liters of water.

c) Part b) is linear.

The equation Water in pool = Water filling rate × Time represents a linear relationship because the amount of water in the pool increases linearly with respect to time.

Each hour, the pool fills up with a constant rate of 10 liters, leading to a proportional increase in the total volume of water in the pool.

Answer:f = 57 g = 33

Step-by-step explanation:

Add f and g together and make them equal 90 and then solve for x and plug x back in to both angles 57 and 33

The equation of inequalities that satisfy the condition is 4x+2y< 260 and x >25.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. The inequalities are usually denoted by less than or greater than symbol depending on the given conditions and scenario.

According to the question,

Let hamburgers be denoted as x and hot dogs be denoted as y.

The cost of x hamburgers is thus 4x and the cost of y hot dogs is 2y.

Since the cost cannot be more than $260 the equation is:

4x+2y < 260.

Now, the hamburgers need to be greater than 25. This is represented as follows:

x > 25.

Hence, the two inequalities that satisfy the condition are:

4x+2y <260

x> 25.

Answer:D)  GH and G'H' AREN'T Congruent

Step-by-step explanation:

Dilations are not rigid transformations and therefore do not preserve length but only angle size and shape. GH and G'H' are not equal or congruent.

The mean and standard deviation of the scores are given below:

• Mean = 75

• Standard deviation = 4

We make use of the z-score formula below:

Part A (between 63 and 87)

First, we determine the z-scores.

Part B (Above 83)

Therefore, the percentage of scores that were above 83 is 2.28%.

The PERCENTILE function returns the x value that corresponds to the 90th percentile.

To find the x value associated with the highest 10%, you can use the PERCENTILE function in Excel.

Assuming the x values are in a range of cells, the following expression can be used to find the x value associated with the highest 10%: =PERCENTILE(range, 1-0.1*(AVERAGE(range)))

The range in this expression is the range of cells containing the x values, and AVERAGE(range) computes the mean of the x values. The 90th percentile is calculated by the expression 1-0.1*(AVERAGE(range)), which is the value associated with the highest 10%..

Finally, the PERCENTILE function returns the x value that corresponds to the 90th percentile.

The square root of (2x - 1)^2 is 2x - 1. So, the length of each side of the square is 2x - 1

To determine the length of each side of the square, we need to factor the area expression completely. The area of a square is equal to the square of its side length. So, we need to find the square root of the given area expression to get the length of each side.
The given area expression is 4x^2 - 12x + 9. We can factor it by looking for two numbers that multiply to give 9 (the constant term) and add up to -12 (the coefficient of the middle term).
The factors of 9 are 1 and 9, and their sum is 10. However, we need the sum to be -12. So, we need to consider the negative factors of 9, which are -1 and -9. Their sum is -10, which is closer to the desired sum of -12. So, we can write the middle term as -10x by using -1x and -9x.
Now, we can rewrite the area expression as (2x - 1)^2. Taking the square root of this expression gives us the length of each side of the square.
To summarize, the length of each side of the square is 2x - 1.

The margin of error for the confidence interval is approximately 0.014, indicating that the estimate of the proportion of dissatisfied customers could be off by approximately plus or minus 0.014. This means that we can be 95% confident that the true proportion of dissatisfied customers falls within the range of the estimated proportion ± 0.014.

(a) To find the sample size needed to achieve a margin of error of about 0.015 with a 95% confidence level, we can use the formula for sample size calculation for proportions:

n = (Z^2 * p * (1-p)) / E^2

Where:

n = sample size

Z = critical value (corresponding to the desired confidence level)

p = estimated proportion of the population

E = margin of error

In this case, the estimated proportion of dissatisfied customers is 0.17, and the desired margin of error is 0.015. Since we want a 95% confidence level, the critical value can be obtained from a standard normal distribution table. The critical value for a 95% confidence level is approximately 1.96.

Plugging these values into the formula, we have:

n = (1.96^2 * 0.17 * (1-0.17)) / 0.015^2

n ≈ 1901.63

Therefore, the sample size needed is approximately 1902.

(b) If 25% of the sample say they are not satisfied, we can calculate the margin of error using the following formula:

MoE = Z * sqrt((p * (1-p)) / n)

Where:

MoE = margin of error

Z = critical value (corresponding to the desired confidence level)

p = proportion of the sample

n = sample size

Using the same critical value of 1.96 for a 95% confidence level and plugging in the values:

MoE = 1.96 * sqrt((0.25 * (1-0.25)) / 1902)

MoE ≈ 0.014

The Volume of the Pyramid=19.19in³

Surface Area of  the Pyramid=48.65in²

Volume is a unit of measurement for the area occupied in three dimensions. It is widely quantified and measured using SI-derived units, alternative imperial units, or US standard units (such as the gallon, quart, cubic inch). Volume and length (cubed) have a similar meaning.

First, volume was calculated using naturally occurring vessels with a similar shape, and then using standardized containers. Calculating the volume of numerous common three-dimensional forms is made simple by arithmetic formulas. The volumes of increasingly complicated shapes can be calculated using integral calculus.

Given that,

Height of the pyramid =4.7

Pyramid's slant height= 5.2

Base of pyramid is a square with side=3.5

Volume of the pyramid=(1/3)(3.5×3.5)×(4.7)

=19.19 in³

The surface area of a pyramid=((1/2)×(4×3.5)×5.2)+(3.5×3.5)

=18.65in²

Therefore, the volume of the pyramid=19.19 in³

And the surface area of the pyramid=18.65in²

Answer:

\(x=\frac{ln(12)}{3}\)

Step-by-step explanation:

We can solve this equation by taking the natural log of both sides.

This gives us the equation: \(ln(e^{3x})=ln(12)\)

And the definition of natural log is basically, "what do I have to raise e to, to get this result"

The result is just e^3x, so I have to raise e to what? Well that's just 3x, you could also use log properties to bring the exponent in front and realize ln(e) = 1

So this gives us: \(3x=ln(12)\)

Now divide both sides by 3: \(x=\frac{ln(12)}{3}\)
