If the domain is {0, 2,-6}, what is the range of y = -2x + 3?

Answer:

\(W(t)=5(2^t)\)

Step-by-step explanation:

Given that the Newly planted seedlings approximately double their weight every week and a seedling weighing 5 grams is planted at time t = 0 weeks. This represent an exponential function with an equation in the form:

\(W(t)=ab^t\).

W(t) is the weight in t weeks, t is the weeks and a is the weight when t = 0. At t = 0, W = 5 g:

\(W(t)=ab^t\\W(0)=ab^0\\5=ab^0\\a=5\)

Since the weight double every week, b = 2. The exponential function is given as:

It is most likely that John and Dawn live in a "married couple with children" household. They have been married for over 20 years and have three children residing with them in their home in Northville, MI.

John and Dawn have been married for over 20 years and have lived in their home in Northville, MI with their three children for most of those years. To determine the type of household they live in, we can consider the various household classifications provided by the Census Bureau.

Married couple with children: This classification applies to households where a married couple resides with one or more children who are under the age of 18. Since John and Dawn have three children, it is possible that they fall under this category.

Married couple without children: This classification includes households where a married couple resides without any children under the age of 18. However, since John and Dawn have three children, this classification is not applicable to their situation.

Single-parent household: This classification applies when a single parent resides with one or more children under the age of 18. Since John and Dawn are married, this classification is not relevant in their case.

Other household types: There are several other household types defined by the Census Bureau, such as multi-generational households, unmarried partner households, and non-family households. However, based on the given information, none of these classifications seem to apply to John and Dawn's situation.

Considering the information provided, it is most likely that John and Dawn live in a "married couple with children" household. They have been married for over 20 years and have three children residing with them in their home in Northville, MI.

The gate code to a gated community consists of the # key, followed by 3 letters chosen from the English alphabet, followed by 3 digits. The total number of possible gate codes is 17.576,000.

To find the total number of possible gate codes for the gated community, we need to determine the number of choices for each part of the code and multiply them together.
1. The gate code starts with the # key, which is constant, so there's only 1 choice for this part.
2. The next part consists of 3 letters chosen from the English alphabet. There are 26 letters in the alphabet, and each of the 3 positions can be filled with any of those letters. So, the number of choices for this part is 26 * 26 * 26.
3. The last part of the code consists of 3 digits. Since there are 10 digits (0-9), there are 10 choices for each digit. Therefore, there are 10 * 10 * 10 choices for this part.
Now, we'll multiply the number of choices for each part together to get the total number of possible gate codes:
1 * (26 * 26 * 26) * (10 * 10 * 10) = 1 * 17576 * 1000 = 17,576,000
So, there are a total of 17,576,000 possible gate codes for the gated community.

Answer:

x = 1.5 , y = 2.5

Step-by-step explanation:

4x + 5y = 18.5 → (1)

2x + 4y = 13 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the x- term

- 4x - 8y = - 26 → (3)

add (1) and (3) term by term to eliminate x

- 3y = - 7.5 ( divide both sides by - 3 )

y = 2.5

Substitute y = 2.5 into either of the 2 equations and solve for x

Substituting into (1)

4x + 5(2.5) = 18.5

4x + 12.5 = 18.5 ( subtract 12.5 from both sides )

4x = 6 ( divide both sides by 4 )

x = 1.5

Hi there!

\(\large\boxed{h = \frac{15x}{y}}\)

Recall the volume of a pyramid is:

V = 1/3(bh)

We are given the volume and side length of the base. Find the area of the base:

A = s²

A = (5xy²)² = 25x²y⁴

Plug in the solved for base:

125x³y³ = 1/3(25x²y⁴)h

To isolate for h, begin by multiplying both sides by 3:

375x³y³ = (25x²y⁴)h

Divide both sides by 25x²y⁴. Use the following exponent property:

xᵃ / xᵇ = xᵃ⁻ᵇ

Thus:

375x³y³ / 25x²4⁴ = 15x/y.

The height must be equal to:

\(h = \frac{15x}{y}\)

The given statement When inserting a value into a partially-filled array in descending order, the insertion position is indeed the index of the first value smaller than the value being inserted is true.

What is partially filled array?

A partially filled array, also known as a sparse array, is an array data structure where not all elements are populated with values. In other words, it is an array that contains empty or uninitialized elements.

When inserting a new value into this sorted array, we start from the beginning and compare the value with each existing element until we find the first element that is smaller. The insertion position for the new value is the index of this first smaller element.

For example, if we have a partially-filled array [10, 8, 5, 3] and we want to insert the value 6 into the array in descending order, we compare 6 with each element from left to right. The first element smaller than 6 is 5, and its index is 2. Therefore, the insertion position for the value 6 would be index 2, resulting in the updated array [10, 8, 6, 5, 3].

The equation of line passes through the points (- 9, 6) and (- 7, -8) will be;

⇒ y = - 7x - 57

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (- 9, 6) and (- 7, -8)

Now,

Since, The equation of line passes through the points (- 9, 6) and (- 7, -8)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 8 - 6) / (- 7 - (-9))

m = - 14 / 2

m = - 7

Thus, The equation of line with slope - 7 is,

⇒ y - 6 = - 7 (x - (-9))

⇒ y - 6 = - 7 (x + 9)

⇒ y - 6 = - 7x - 63

⇒ y = - 7x - 63 + 6

⇒ y = - 7x - 57

The answer is 5y.

A demand that is completely inelastic is one in which a change in price has no impact on the quantity demanded. The demand curve in this situation is vertical, and there is no demand elasticity.

A demand curve in economics is a graph showing the relationship between the price of a specific good (the y-axis) and the amount of that good that is desired at that price (the x-axis). Demand curves can be applied to both the price-quantity relationship for a single consumer (an individual demand curve) and for all consumers in a specific market.

Demand curves are typically thought to slope downward, as the adjacent image illustrates. This is due to the law of demand, which states that for the majority of goods, the quantity demanded decreases as the price increases. This law does not apply in some peculiar circumstances. These include Veblen goods, Giffen goods, and speculative bubbles, in which consumers are drawn to a commodity if its price increases.

The probabilities of specific z-values can be determined using the standard normal distribution table. To find the value of z when a certain percentage of all possible z-values are larger, you can use the inverse standard normal distribution.

To determine the probability of a specific z-value, you can use the standard normal distribution table. The "z" value represents the number of standard deviations away from the mean. Since the mean of a standardized normal distribution is 0 and the standard deviation is 1, the z-value itself is equal to the probability.

Since you didn't provide a specific z-value, it's not possible to determine the probability.

To find the probability of a specific z-value, such as 1.96z, you can use the standard normal distribution table. The z-value in this case is 1.96, so you would look up the probability associated with that z-value in the table.

To find the value of z when only a certain percentage of all possible z-values are larger, you would need to use the inverse standard normal distribution. This is commonly referred to as the z-score.

By using a z-table or a calculator with the inverse normal function, you can find the z-value that corresponds to a given percentage. This z-value will give you the number of standard deviations above the mean.

In conclusion, the probabilities of specific z-values can be determined using the standard normal distribution table. To find the value of z when a certain percentage of all possible z-values are larger, you can use the inverse standard normal distribution.

A. It’s asking what the last test must have to be (x) for all five tests to average out to an 80. This can be represent by:

(95+76+77+84+x)/5=80

The first four numbers are the existing test scores and x is the score you need. This is all divided by five so that you can find the average of all of these added together, which will equal 80, because that’s the grade you’re trying to get. Next, just solve for x:

Nicole would have $73,036.70 - $56,772.25 = $16,264.45 more money than Bentley after 14 years at the given interest rate.

Simple interest refers to an interest rate where the interest is just calculated on the principal sum of money. For the duration of the loan or investment, the interest rate is only applied once to the principal sum. On the other hand, compound interest is a type of interest where the interest is computed using both the principal and the interest from prior periods. After each compounding period, the interest rate is applied to the newly created balance.

The compound interest is given as:

\(A = P * e^{(rt)}\)

Substituting the given values:

\(A = 29000 * e^{(0.0541 * 14)} = $73,036.70\)

Now, after 14 years:

\(A = P * (1 + r/100)^t\)

Substituting the values:

\(A = 29000 * (1 + 0.04885)^{14} = $56,772.25\)
