aqueline spent $150 for supplies and gas to start a lawn-mowing service. she charges $25 for each lawn she mows. in the first week jaqueline made $50 after the cost of supplies and gas was deducted. which equation represents this situation, where x is the number of lawns jaqueline mowed during the first week?

Answers

Answer 1

Note that the equation that represents this situation is 25x - 150 = 50 (Option A).

How is this so?

In this equation, x represents the number of lawns Jacqueline mowed during the first week.

The left side of the equation, 25x, represents the total amount of money Jacqueline earned from mowing x lawns at a rate of $25 per lawn.

The right side of the equation, 150 + 50, represents the total cost of supplies and gas ($150) deducted from her earnings, leaving her with a profit of $50.

Thus, it is correct to state that Option A is the right answer.

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 3 units, then what is the value of k? (1 point)
k = −3
k equals negative one third
k equals one third
k = 3

Answers

The value of k for the translation of function f(x) to obtain function g(x) is given as follows:

k = -3.

What are the translations?

There are four translations, and they are defined as follows:

Translation left a units: f(x + a).Translation right a units: f(x - a).Translation up a units: f(x) + a.Translation down a units: f(x) - a.

(hence we use these bullet points to identify the correct translation for this problem).

In this problem, the translation is that function f(x) was shifted down three units to obtain function g(x), hence the definition is given as follows:

g(x) = f(x) - 3.

Hence the value of the coefficient k is given as follows:

k = -3.

(meaning that the correct option is given by the first option in this problem).

Answers

To achieve better accuracy when adding the numbers from 0.01 to 1.00, it is recommended to add the numbers in ascending order (from smallest to largest) to minimize the accumulation of rounding errors and maintain higher precision during intermediate calculations. Thus, starting with 0.01 and ending with 1.00 would provide better accuracy.

To achieve better accuracy when adding the numbers from 0.01 to 1.00, it is generally recommended to use an order that minimizes the accumulation of rounding errors. In this case, it is advisable to start with the smaller numbers and progress towards the larger ones.

By adding the numbers in ascending order (from 0.01 to 1.00), the rounding errors at each step will have a smaller impact on the overall result. This is because adding smaller numbers together first helps maintain a higher level of precision during intermediate calculations.

The weekly salaries of elementary school teachers in one state are normally distributed with a mean of $595 and a standard deviation of $43. What is the probability that a randomly selected elementary school teacher earns more than $555 a week?

Answers

The probability that a randomly selected elementary school teacher earns more than $555 a week is approximately 0.8238 or 82.38%.

We can use the standard normal distribution to solve this problem by standardizing the value of $555 and finding its corresponding probability.

The standardized value of $555 is:

z = (x - μ) / σ = (555 - 595) / 43 = -0.93

where x is the weekly salary we're interested in, μ is the mean weekly salary, and σ is the standard deviation of weekly salaries.

We can now look up the probability of a standard normal random variable being greater than -0.93 in a standard normal distribution table, or use a calculator or statistical software. The probability is approximately 0.8238.

Therefore, the probability that a randomly selected elementary school teacher earns more than $555 a week is approximately 0.8238 or 82.38%.

C. A'(-5, 2) and B'(-3,6)
D. A'(5,-2) and B'(3,-6)

What are the coordinates of A' and B'when AB is reflected in the x-axis?A. A'(2,-5) and B'(-3, 6)B. A'(2,-5)

Answers

Answer:

When reflecting a point or line segment across the x-axis, the y-coordinate changes sign while the x-coordinate remains the same. In this case, we are given the points A (2,5) and B (-3,6) and asked to find their reflections in the x-axis, represented by the points A’ and B’.To reflect point A across the x-axis, we simply change the sign of the y-coordinate while keeping the x-coordinate the same. So, if A is (2,5), its reflection A’ is (2,-5). We can follow the same procedure for point B. If B is (-3,6), its reflection B’ is (-3,-6).From this calculation, we see that answer choice A is the correct one. Therefore, A’(2,-5) and B’(-3,6) represent the points that are the reflections of A and B, respectively, across the x-axis.The reflection of a point across the x-axis can also be visualized as the point being mirrored across the x-axis as if it were a horizontal mirror. In this case, point A is reflected to the point A’ which is the same distance above the x-axis as A is below the x-axis. Similarly, point B is reflected to point B’ which is the same distance below the x-axis as B is above the x-axis.It’s also worth noting that reflecting a point or line segment across the x-axis is an example of a transformation in coordinate geometry. Translations, reflections, rotations, and dilations are all examples of transformations that can be used to manipulate geometric figures on the coordinate plane.Overall, reflecting a point or line segment across the x-axis is a relatively simple calculation that involves negating the y-coordinate. In the context of coordinate geometry, it’s important to understand the basic transformations like these and how they can be used to manipulate shapes and figures on the coordinate plane.

Find the slope of the tangent line to the curve y=x^2-15^2 at x=4. Then write the equation of this tangent line.

Answers

The slope of the tangent line to the curve\(y = x^2 - 15^2 at x = 4\) is 8. The equation of this tangent line is y = 8x - 47.

To find the slope of the tangent line, we need to calculate the derivative of the given curve with respect to x. Taking the derivative of y = \(x^2 - 15^2\)using the power rule, we get dy/dx = 2x. Substituting x = 4 into the derivative, we find that the slope of the tangent line at x = 4 is 2(4) = 8.
To find the equation of the tangent line, we use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point on the curve where the tangent line passes through, and m is the slope of the tangent line. Since the tangent line passes through the point (4, y), we can substitute x1 = 4 and y1 = \(4^2 - 15^2 =\) -191 into the equation.
Plugging in these values, we get y - (-191) = 8(x - 4), which simplifies to y + 191 = 8x - 32. Rearranging the equation, we have y = 8x - 32 - 191, which further simplifies to y = 8x - 223. Therefore, the equation of the tangent line to the curve y = \(x^2 - 15^2 at\) x = 4 is y = 8x - 223.

3000=150(1+. 025/12)^(12t)

Can someone one help

Answers

The equation 3000=150(1+. 025/12)^(12t) can be solved using logarithm  functions. The value of t can be found by isolating it on one side of the equation. After simplification, the final answer is approximately 4.37 years.

To solve the equation, begin by dividing both sides by 150:

3000/150 = (1 + 0.025/12)^(12t)

Simplify the left-hand side:

20 = (1.002083)^12t

Take the logarithm of both sides using the natural logarithm (ln):

ln(20) = ln[(1.002083)^12t]

Use the logarithm rule to bring down the exponent:

ln(20) = 12t ln(1.002083)

Divide both sides by ln(1.002083):

t = ln(20) / [12 ln(1.002083)]

Using a calculator, the final answer is approximately 4.37 years. Therefore, after 4.37 years, an initial investment of $150 at a monthly interest rate of 2.5% would grow to $3000.

Convert the formula f(t)=275e^0.14t to the form f(t)=ab^t. Write your answer using function notation. Give answers accurate to three decimal places

Answers

The formula f(t) = 275e^(0.14t) can be written in the form f(t) = 275(1.150)^t. Let's determine:

To convert the formula f(t) = 275e^(0.14t) to the form f(t) = ab^t, we need to rewrite it with a base "b" raised to the power of "t".

1. Start with the function f(t) = 275e^(0.14t).

2. Identify the base "b" and the coefficient "a" that will allow us to rewrite the expression in the desired form.

3. Notice that e^(0.14t) is equivalent to (e^0.14)^t. Therefore, we can rewrite the function as:

  f(t) = 275(e^0.14)^t

4. Simplify the term e^0.14 to a decimal value.

  Using a calculator, we find that e^0.14 is approximately 1.150.

5. Substitute this value back into the equation to obtain:

  f(t) ≈ 275(1.150)^t

6. Finally, we can rewrite the formula in the desired form:

  f(t) = 275(1.150)^t

  The coefficient "a" is 275, and the base "b" is approximately 1.150.

Therefore, the formula f(t) = 275e^(0.14t) can be written in the form f(t) = 275(1.150)^t.

It's important to note that the approximation of e^0.14 as 1.150 introduces a small error in the conversion. However, for most practical purposes, this approximation is sufficiently accurate.

This form allows us to see that the function f(t) is an exponential function where the initial value (when t = 0) is 275, and the base of the exponent is approximately 1.150. The value of "t" represents the time or input variable, and the function f(t) gives the output value or quantity at a given time.

Answers

The answer obtained from multiplying the measurements 64.49 and 6.57 is 423.70.

 

 

According to the rules governing significant figures, the result of a multiplication or division should have the same number of significant figures as the measurement with the fewest significant figures.

In this case, both measurements, 64.49 and 6.57, have four significant figures each. When multiplied together, the result is 423.6993. However, since the measurement 6.57 has the fewest significant figures, the final answer should be rounded to match that.

Therefore, the answer is rounded to three decimal places, resulting in 423.700. The zero at the end is included to indicate that the measurement is known to that level of precision.

Hence, considering the rules of significant figures, the answer obtained from multiplying the measurements 64.49 and 6.57 is 423.700.
