Hey! I need help on this question and I would be so happy if you helped me!

By using the definition of inverse functions we can see that:

a) g(7) = -10

b)(-10,7) is a point on h(x).

c)(7, -10) is a point on j(x)

Remember that if two functions f(x) and g(x) are inverses, then:

f(y) = x

g(x) = y

And also g(f(x)) = x = g(f(x)).

Here we know that functions h(x) and j(x) are inverses, and we also know that:

h(-10) = 7

So for the input -10, we have the output 7.

Then, by using the relation written above, we know that for the inverse function we must have:

j(7) = -10

That is the answer for a.

And for b and c the notation is (input, output), then:

The answer is 1570. To evaluate the expression 547+233×5−142, we need to follow the order of operations, which is PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction).

There are no parentheses or exponents, so we start with multiplication and division from left to right.

233×5 = 1165

Then, we can simplify the expression to:

547 + 1165 - 142

Next, we add and subtract from left to right:

547 + 1165 = 1712

1712 - 142 = 1570

Therefore , the solution of the given problem of inequality comes out to be Gary and Jamal are the students who created an inequality that holds true for all values in the collection "0, 1, 3, 4, 6, 12".

Algebra does not have an equal symbol, but a partner or group of integers can be used to represent the difference. Equilibrium is typically followed by equity. Inequality comes from the continued divergence of ideals. Disparity and expression fairness are not identical. Despite the fact that the parts are typically not connected or close to one another, that was our most popular symbol. (). Any difference, no matter how small, can be used to determine worth.

Here,

We can test each inequality with each value in the set, 0 through 1, 3, 4, 6, and 12, to identify which inequality holds true for all values.

6 > 0.5t, where t is a member of the collection, is Gary's inequality. When we compare each value in the collection to this inequality, we discover:

When t = 6: 6 > 0.5(6) is true

When t = 12: 6 > 0.5(12) is true

Therefore, for each value in the collection, Gary's inequality holds true.

30 - t  18 is Nancy's inequality, where t is a number from the collection. When we compare each value in the collection to this inequality, we discover:

When t = 6: 30 - 6 ≤ 18 is true

When t = 12: 30 - 12 ≤ 18 is true

Therefore, not all values in the collection satisfy Nancy's inequality.

The point (2,2) may be considered an anomaly and should be investigated further to determine if it is a valid data point or if it should be excluded from the analysis.

The relation of the point (2,2) to the line of best fit can be determined by analyzing the residual value of this point. The residual value is the difference between the actual y-value and the predicted y-value based on the line of best fit. If the residual value is close to zero, then the point lies on the line of best fit. If the residual value is positive, then the actual y-value is higher than the predicted y-value, and if the residual value is negative, then the actual y-value is lower than the predicted y-value.

Unfortunately, the data necessary to determine the residual value of the point (2,2) is not provided in the question. Therefore, it is impossible to determine the exact relation of this point to the line of best fit.

However, we can make some generalizations based on the location of the point relative to the trend of the data.

If the point (2,2) lies close to the line of best fit, with a residual value close to zero, then it can be said that the point follows the trend of the data and is a typical data point. However, if the point lies far away from the line of best fit, with a large positive or negative residual value, then it can be said that the point is an outlier and does not follow the trend of the data.

The value for a is 1 and the remainder when P(x) is divided by x - 1 is 2.

What is polynomial remainder theorem?

It states that the remainder of the division of a polynomial f(x) by a linear polynomial x-r is equal to f(r).

The divisor in this case is x - a, where "a" is the value we need to determine.

We can see that the given polynomial 2x³ + 5x² - 12x + 9 + x - 3 has a term of x in addition to the other terms. This means that the divisor must also have a term of x in it.

So, we can write the divisor as x - a and set x - a = 0 to solve for "a":

x - a = 0

=> x = a

Therefore, "a" must be equal to 1 since there is a term of x in the polynomial.

To find the remainder, we need to evaluate P(a) where P(x) = 2x³ + 5x² - 12x + 9 + x - 3 and a = 1.

P(a) = 2(1)³ + 5(1)² - 12(1) + 9 + (1) - 3 = 2 + 5 - 12 + 9 + 1 - 3 = 2

So, the remainder when P(x) is divided by x - 1 is 2.

The smallest positive integer y such that the product xy is a perfect cube is 3.

To find the value of y, we need to factorize x, which is 7 * 24 * 48.

We can then find the prime factorization of xy, which will help us determine the smallest integer y that will make the product a perfect cube.

Since 7, 24, and 48 are already factored, we can express x as:

x = 2⁴ * 3 * 7²

To make xy a perfect cube, we need to ensure that the exponents of all the prime factors are multiples of 3.

Therefore, we need to add a factor of 3 to the exponent of 2 in x to make it a multiple of 3. This gives us:

xy = 2⁷ * 3² * 7²

The smallest integer y that can make this product a perfect cube is 3, because we need to add a factor of 1 to the exponent of 2 in xy to make it a multiple of 3, and the smallest integer that can achieve this is 3.

Thus, the smallest positive integer y such that the product xy is a perfect cube is 3.

In conclusion, the relation R on the set of all integers satisfies reflexivity and symmetry but not transitivity.

To determine which properties the relation R on the set of all integers satisfy, we need to check for reflexivity, symmetry, and transitivity.

1. Reflexivity: A relation R is reflexive if for every element a in the set, (a, a) ∈ R.
In this case, we need to check if a * a ≥ 1 for all integers a.
Since any integer squared (a * a) is greater than or equal to 1, R is reflexive.

2. Symmetry: A relation R is symmetric if for every pair (a, b) ∈ R, (b, a) also ∈ R.
In this case, we need to check if a * b ≥ 1 implies b * a ≥ 1.
Since multiplication is commutative (a * b = b * a), the condition holds true, and R is symmetric.

3. Transitivity: A relation R is transitive if for every (a, b) ∈ R and (b, c) ∈ R, (a, c) also ∈ R.
In this case, we need to check if a * b ≥ 1 and b * c ≥ 1 imply a * c ≥ 1.
Let's take the counterexample: a = -1, b = 2, and c = -1. We have -1 * 2 ≥ 1 and 2 * -1 ≥ 1, but -1 * -1 ≥ 1 is false.

Therefore, R is not transitive.

The common ratio/multiplier/base of the exponential function that better models the given data is approximately 1.123.

What is expression ?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, division, exponents, and roots) that can be evaluated or simplified to obtain a numerical value or another expression.

To find the common ratio/multiplier/base of the exponential function that better models the given data, we need to use the formula for exponential functions:

[tex]f(x) = ab^x[/tex]

where a is the initial value and b is the common ratio/multiplier/base.

We can use the given data points to form a system of equations:

[tex]2 = ab^{(42,458)}\\ \\3 = ab^{(41,776)}\\ \\4 = ab^{(40,654)}\\ \\5 = ab^{(39,841)}\\ \\[/tex]

We can divide each equation by the previous equation to eliminate "a" and obtain a ratio of "b" values:

[tex]b^{(42,458-41,776)} = 3/2\\ \\ b^{(41,776-40,654)} = 4/3\\ \\ b^{(40,654-39,841)} = 5/4\\ \\[/tex]

Simplifying each exponent, we get:

[tex]b^{682} = 3/2\\ \\b^{1122} = 4/3\\ \\b^{813} = 5/4\\ \\[/tex]

Taking the cube root of the first equation, the fourth root of the second equation, and the fifth root of the third equation, we get:

[tex]b^{(682/3)} = (3/2)^{(1/3)} = 1.245\\ \\ b^{(1122/4)} = (4/3)^{(1/4)} = 1.090\\ \\ b^{(813/5)} = (5/4)^{(1/5)} = 1.035\\ \\[/tex]

Taking the average of these values, we get:

b ≈ (1.245 + 1.090 + 1.035) / 3 ≈ 1.123

Therefore, the common ratio/multiplier/base of the exponential function that better models the given data is approximately 1.123.

The probability that a flight between New York City and Chicago is less than 64 minutes is 0.28, or 28%.

Since the time to fly between New York City and Chicago is uniformly distributed between 50 and 100 minutes, we can use the formula for the uniform probability density function (PDF) to find the probability that a flight is less than 64 minutes:

f(x) = 1 / (b - a), for a ≤ x ≤ b

where a = 50 and b = 100 are the minimum and maximum times, respectively.

To find the probability that a flight is less than 64 minutes, we need to integrate the PDF from a to 64:

P(X < 64) = [tex]\int\limits^{64}_{50}[/tex] f(x) dx = [tex]\int\limits^{64}_{50}\\[/tex](1 / 50) dx = (1 / 50) * [x]|₅₀ ⁶⁴

Answer:

Step-by-step explanation:

If there were 8 glasses of juice, and 350 ml was poured into each glass, then the total amount of juice poured into the glasses would be 8 x 350 = 2800 ml.

After pouring this much juice, John was still left with 200 ml juice in the jar.

Therefore, the capacity of the jar would be the total amount of juice poured into the glasses plus the amount remaining in the jar, which is 2800 ml + 200 ml = 3000 ml.

To convert this volume to liters, we can divide by 1000. Therefore, the capacity of the jar in liters would be 3000 ml / 1000 = 3 liters.

So, the capacity of the jar is 3 liters.

The monthly percentage rate is 1.45%, and the APR is 17.4%.

To calculate the monthly percentage rate, we can divide the finance charge by the average daily balance, then multiply by 100 to convert to a percentage

Monthly percentage rate = ($8.12 / $560) x 100

Monthly percentage rate = 0.0145 x 100

Monthly percentage rate = 1.45%

To calculate the APR (annual percentage rate), we need to multiply the monthly percentage rate by the number of months in a year:

what are perpendicular lines?

Perpendicular lines are two lines that intersect at a 90-degree angle, forming four right angles at the point of intersection. In other words, if you were to draw a perpendicular line from one of the lines to the other at their point of intersection, it would form a right angle with each of the original lines.

Without having access to more information about how Lucinda selected the sample of students, it's difficult to determine whether or not the sample is truly random.

However, there are a few things that we can consider when trying to determine whether or not the sample is random. For example:

Did Lucinda use a random selection method to choose the students? If she simply surveyed her friends or classmates, for example, the sample would not be random.

Did Lucinda make any effort to ensure that the sample is representative of the larger population of students? For example, did she make sure to include students from a variety of grades, genders, and ethnic backgrounds.
