Answer:
= 9
Step-by-step explanation:
Slope = (y1-y2)/(x1-x2)
= -12-6/4-6
= -18/-2
= 9
To solve the equation(x+5)^2 =9, Tyler first expanded the squared expression. Here is his incomplete work:
(x+5)²-9
(x+5) (x+5)=9
x^2+5x+5x+25=9
x²+10x+25=9
1. Complete Tyler's work and solve the equation.
2. Clare saw the equation (x+5)^2=9 and thought, "There are two numbers, 3 and -3, that equal 9 when squared.
This means x+5 is either 3 or it is -3. I can find the values of x from there." Use Clare's reasoning to solve the
equation.
1. the solutions to the equation (x+5)² = 9 are x = -8 and x = -2.
2.Clare's reasoning correctly yields the solutions x = -2 and x = -8, which match the solutions obtained through completing Tyler's work.
1. Let's complete Tyler's work and solve the equation:
(x+5)² - 9
(x+5)(x+5) = 9
Using the FOIL method (First, Outer, Inner, Last) to expand the product:
x(x+5) + 5(x+5) = 9
x² + 5x + 5x + 25 = 9
x² + 10x + 25 = 9
Now, let's rearrange the equation to bring all terms to one side:
x² + 10x + 25 - 9 = 0
x² + 10x + 16 = 0
To solve this quadratic equation, we can factor it:
(x+8)(x+2) = 0
Setting each factor equal to zero:
x+8 = 0 or x+2 = 0
Solving for x in each equation:
x = -8 or x = -2
Therefore, the solutions to the equation (x+5)² = 9 are x = -8 and x = -2.
2. Clare's reasoning is based on the fact that if a squared term equals a constant (in this case, 9), then the square root of that constant will have two possible solutions: one positive and one negative. By considering (x+5) as either 3 or -3, Clare is essentially setting up two separate equations:
x+5 = 3 or x+5 = -3
Solving for x in each equation:
For x+5 = 3:
x = 3 - 5
x = -2
For x+5 = -3:
x = -3 - 5
x = -8
Thus, Clare's reasoning correctly yields the solutions x = -2 and x = -8, which match the solutions obtained through completing Tyler's work.

hiero earns $17.50/hour and worked 41 hours this week. he is covered under the flsa. how much is his regular pay?
Hiero earns $17.50 per hour and worked 41 hours this week. Under the Fair Labor Standards Act (FLSA), non-exempt employees are entitled to receive overtime pay at a rate of 1.5 times their regular pay for hours worked beyond 40 hours in a workweek.
To calculate Hiero's regular pay for the week, we multiply his hourly rate by the number of regular hours worked, which is 40 hours in this case. Therefore, Hiero's regular pay for the week is:
Regular pay = Hourly rate x Regular hours worked
Regular pay = $17.50 x 40
Regular pay = $700
Now, to determine whether Hiero is eligible for overtime pay, we subtract the number of regular hours worked from the total number of hours worked. In this case, the total number of hours worked is 41. Therefore, Hiero worked 1 hour of overtime, for which he is entitled to receive overtime pay.
To calculate Hiero's overtime pay, we multiply his hourly rate by 1.5 and then by the number of overtime hours worked, which is 1 hour in this case. Therefore, Hiero's overtime pay for the week is:
Overtime pay = Hourly rate x 1.5 x Overtime hours worked
Overtime pay = $17.50 x 1.5 x 1
Overtime pay = $26.25
Therefore, Hiero's total pay for the week, including regular pay and overtime pay, is:
Total pay = Regular pay + Overtime pay
Total pay = $700 + $26.25
Total pay = $726.25
Hiero's regular pay for the week is $700.

Determine if the following describes a binomial experiment. If not, give a reason why not: Two cards are randomly selected without replacement from a standard deck of playing cards, and the number of kings (K) is recorded. a. o not binomial; each trial has more b. not binomial; the number of trials is than 2 outcomes not fixed c. O not binomial; the trials are not d.O binomial experiment independent
The given scenario does not describe a binomial experiment. The reason is that a binomial experiment must satisfy four conditions: fixed number of trials, two possible outcomes, independent trials, and constant probability of success.
In this case, the number of trials is not fixed since two cards are selected without replacement from a standard deck. The number of outcomes for each trial is not limited to two because it depends on the number of kings selected, which can vary. Therefore, the scenario does not meet the requirements for a binomial experiment.
Additionally, the independence of trials is an important criterion for a binomial experiment. In this scenario, the selection of cards is not independent since the second card chosen depends on the outcome of the first card selection. Therefore, the correct answer is option b: not binomial; the number of trials has more than 2 outcomes.

In Act 2 of A Raisin in the Sun, George Murchison's arrival changes the mood of the scene as he complains that Beneatha is giving them a lecture on their African past. George's comments create tension and conflict among the characters, particularly with Beneatha, who is exploring her African heritage. His attitude towards Beneatha's interest in her roots is dismissive and condescending, which generates discomfort and disagreement among the characters. George's arrival highlights the cultural differences between him and the Younger family and demonstrates the generational and ideological divides within the African American community.

Tiara earns $33 washing 3 cars. At this rate, how much does Tiara earn washing 9 cars?
Answer:
$99
Step-by-step explanation:
Answer:
$99 (Verified Answer) ✅Step-by-step explanation:
The best way to solve this is to use a proportion. However, since this is a rate, we could also find the unit rate and multiply it by the number of cars Tiara is washing.
Method 1: Proportion\(\frac{33}{3} = \frac{x}{9}\)
3x = 33 x 9
3x = 297
Now, we simply divide by 3 to get $99.
We can check this by substituting the value of x in the original proportion.
3(99) = 33 x 9
297 = 297 ✅
Method 2: Unit RateThe other way to solve this is to divide the whole expression by the number of cars to find the unit rate. In other words, how much money does she get for washing 1 car. We can then multiply this by the number of cars to get the answer.
$33/3 for 3/3 cars
$11 for 1 car
Now, we will multiply by the number of cars she washes in this question, which is 9
$11 x 9 = 99 for 1 x 9 cars
$99 for 9 cars
Again, we have the correct answer, which we have already verified by the process above. As you can see, both methods work. However, the top method is easier and since it uses algebra, is almost foolproof, so long as the algebraic processess are followed.

Supposed that β1=2.78 and β2= −0.09 What is the expected change in m if GDP increases by 4% ? The value of m is expected to by approximately %. (Round your response to the nearest integer)
The expected change in m if GDP increases by 4% is approximately -2%.
The given equation is a logarithmic regression model that relates the quantity of (real) money (m) to the value of (real) gross domestic product (GDP) and the nominal interest rate (R). The equation is expressed as ln(m) = β0 + β1ln(GDP) + β2R, where β1 = 2.78 and β2 = -0.09.
To determine the expected change in m when GDP increases by 4%, we need to substitute the new GDP value into the equation and calculate the resulting change in m.
Let's consider the scenario where the initial GDP increases by 4%. We can calculate the change in m by plugging the new GDP value into the equation:
ln(m') = β0 + β1ln(GDP') + β2R,
where m' represents the new quantity of money and GDP' is the new GDP value.
Since we are interested in the change in m, we subtract the initial equation from the new equation:
ln(m') - ln(m) = β0 + β1ln(GDP') + β2R - β0 - β1ln(GDP) - β2R,
Simplifying the equation:
ln(m'/m) = β1(ln(GDP') - ln(GDP)),
Using the property of logarithms, ln(a) - ln(b) = ln(a/b):
ln(m'/m) = β1ln(GDP'/GDP).
Now, we know that GDP increased by 4%, so GDP'/GDP = 1 + 0.04 = 1.04. Substituting this value into the equation:
ln(m'/m) = β1ln(1.04),
Since ln(1.04) is a constant, we can multiply both sides by β1:
ln(m'/m) * β1 = \(β1^2\) * ln(1.04),
ln(m'/m) * β1 = 2.78 * ln(1.04),
Finally, we can solve for ln(m'/m) by dividing both sides by β1:
ln(m'/m) = 2.78 * ln(1.04) / β1.
Using the given values, β1 = 2.78 and β2 = -0.09, we can calculate the approximate change in m by exponentiating both sides:
m'/m = \(e^(^2^.^7^8^ *^ l^n^(^1^.^0^4^)^ /^ β^1^)\).
Substituting the values, we find:
m'/m ≈ \(e^(^2^.^7^8^ * ^l^n^(^1^.^0^4^)^ / ^2^.^7^8^)\) ≈ \(e^l^n^(^1^.^0^4^)\) ≈ 1.04.
This means that the expected change in m, when GDP increases by 4%, is approximately 1.04. To express this as a percentage change, we subtract 1 and multiply by 100:
Percentage change = (1.04 - 1) * 100 ≈ 4%.
Therefore, the expected change in m, when GDP increases by 4%, is approximately -2% (rounded to the nearest integer).

Answer:
When a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot, is called a mixed fraction.
Step-by-step explanation:
A fraction is a number that is obtained by dividing an integer into equal parts and is expressed as:
\(\frac{numerator}{denominator}\)
An improper fraction is a fraction in which the numerator, that is, the top number, is greater than or equal to the denominator, that is, the bottom number. In contrast, in proper fractions, the numerator is less than the denominator.
Improper fractions can be represented as mixed fractions. A mixed fraction represents a whole number and a proper fraction, in other words, it corresponds to the sum of a whole part plus a fractional part. In summary, mixed fractions are made up of an integer part and a fractional part.
So, when a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot, is called a mixed fraction.

It is not a function thats all I know sry
Step-by-step explanation:
Give the derivative formula for the function. g(x)=15−8ln(x) g ′
(x)=
The derivative formula for the function g(x) = 15 - 8ln(x) is g'(x) = -8/x.
To find the derivative of g(x), we can use the power rule and the chain rule. The power rule states that the derivative of x^n is n*x^(n-1), and the chain rule allows us to differentiate composite functions.
In this case, g(x) is a combination of a constant function (15) and the natural logarithm function (ln(x)). The derivative of the constant term (15) is 0 since it does not depend on x.
The derivative of the natural logarithm function, ln(x), is 1/x. Therefore, using the chain rule, the derivative of -8ln(x) is -8 * (1/x), which simplifies to -8/x.
Hence, the derivative of g(x) = 15 - 8ln(x) is g'(x) = -8/x.
