Answer:(-12,-15)

Step-by-step explanation:

The new coordinate of point (-4,-5) after dilation by a scale factor of 3 centered at the origin is (-12,-15).

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

Given the coordinate (-4,-5)

If we apply a scale factor by 3 on any general coordinate (x,y)

Then,

x → 3x and y → 3y

Similarly

-4 → 3(-4) = -12

-5 → 3(-5) = -15

So the new coordinate will be (-12,-15)

Hence "The new coordinate of point (-4,-5) after dilation by a scale factor of 3 centered at the origin is (-12,-15)".

The probability that Ken will use all the toothpaste in the tube is 7.64%.

From the given information,Mean, μ = 0.13 ounceStandard deviation, σ = 0.02 ounceNumber of times Ken brushes his teeth, n = 6.

The amount of toothpaste Ken squeezes out of the tube each time he brushes is independent and can be modeled by a Normal distribution.

From this information, we can obtain that:Mean of toothpaste used in 6 brushes = n × μ = 6 × 0.13 = 0.78 ounceStandard deviation of toothpaste used in 6 brushes = $\sqrt{n}$ × σ = $\sqrt{6}$ × 0.02 = 0.049 ounce.

To find the probability that Ken will use all the toothpaste in the tube, we need to calculate the probability of the amount of toothpaste used in 6 brushes being more than or equal to 0.85 ounce,
which is the total amount of toothpaste in the tube.P(X ≥ 0.85) = P( Z ≥ (0.85 - 0.78) / 0.049) = P(Z ≥ 1.43) = 1 - P(Z < 1.43)Using standard normal distribution table, we find the value of P(Z < 1.43) as 0.9236. Therefore,P(X ≥ 0.85) = 1 - P(Z < 1.43) = 1 - 0.9236 = 0.0764 or 7.64%.

The amount of toothpaste that Ken squeezes out each time he brushes is modeled by a normal distribution with mean 0.13 ounces and standard deviation 0.02 ounces.

The amount of toothpaste squeezed out at each brushing is independent of the previous amount of toothpaste squeezed out. We want to determine the probability that Ken will use all of the toothpaste in a 0.85-ounce tube if he brushes his teeth six times.

To do so, we first find the mean and standard deviation of the amount of toothpaste squeezed out in six brushes. If Ken brushes his teeth six times, then the mean amount of toothpaste squeezed out is nμ = 6(0.13) = 0.78 ounces. If the amount of toothpaste squeezed out at each brushing is independent, then the standard deviation of the amount of toothpaste squeezed out in six brushes is sqrt(6) * 0.02 = 0.049 ounces.

We now want to find the probability that Ken will use all of the toothpaste in the tube.

This is equivalent to finding the probability that the amount of toothpaste squeezed out in six brushes is greater than or equal to 0.85 ounces, which is the total amount of toothpaste in the tube.

If X is the amount of toothpaste squeezed out in six brushes, then we want to find P(X >= 0.85).We can standardize the distribution of X by subtracting the mean and dividing by the standard deviation.

Z = (X - μ) / σ is the standard normal random variable associated with X. In this case, Z has mean 0 and standard deviation 1. We want to find P(Z >= (0.85 - 0.78) / 0.049), which simplifies to P(Z >= 1.43). Using a standard normal distribution table, we can find P(Z < 1.43) = 0.9236. Therefore, P(Z >= 1.43) = 1 - P(Z < 1.43) = 1 - 0.9236 = 0.0764, or 7.64%.Therefore, the probability that Ken will use all the toothpaste in the tube is 7.64%.

Therefore, the probability that Ken will use all the toothpaste in the tube is 7.64%.

To maximize the amount of peaches produced by the orchard, the peach orchard owner should plant a certain number of trees per acre. The per-tree yield is given by the equation Y = 1200 - 15x, where Y represents the yield per tree and x represents the number of trees planted per acre.

To find the number of trees per acre that maximizes the crop yield, we need to determine the value of x that corresponds to the vertex of the equation. The vertex of a downward-opening parabola, represented by the given equation, occurs at the x-coordinate given by x = -b / (2a).

In this case, the coefficient of x is -15 and the constant term is 0, so b = 0 and a = -15. Substituting these values into the formula, we get x = -0 / (2 * -15) = 0.

While the mathematical calculation suggests that planting zero trees per acre would maximize the yield, this result is not practical. Therefore, the closest feasible value greater than zero would be 1 tree per acre.

For 1 tree per acre, substituting x = 1 into the equation, we find that each tree would produce a yield of Y = 1200 - 15 * 1 = 1185 peaches. Consequently, the resulting total yield would be 1185 peaches per acre.

Number of trees per acre: 1 tree per acre

Total yield: 1185 peaches per acre

Answer:

22.5° and 67.5°

Step-by-step explanation:

The sum of complementary angles equal 90°.

Given that one of the complementary angles is 3 times larger than the other, let "x" represent the other angle.

Thus, the following expression can be written to represent this case:

[tex] x + 3x = 90 [/tex]

Solve for x

[tex] 4x = 90 [/tex]

Divide both sides by 4

[tex] \frac{4x}{4} = \frac{90}{4} [/tex]

[tex] x = 22.5 [/tex]

The measure of the complementary angles are:

x = 22.5°

3x = 3(22.5) = 67.5°

The exponential function f with f(2) = 3 and a doubling time of 5 results in f(27) = 096.

To find f(27) given that f(2) = 3 and the doubling time is 5, we can use the general form of an exponential function: f(x) = a * (2^(x/d)), where a represents the initial value, x is the input value, and d is the doubling time.

Given that f(2) = 3, we can substitute these values into the exponential function equation: 3 = a * (2^(2/5)).

To find the value of a, we can solve the equation for a: a = 3 / (2^(2/5)).

Now, we can substitute a into the exponential function to find f(27): f(27) = (3 / (2^(2/5))) * (2^(27/5)) = 096.

Therefore, the value of f(27) is 096.

---

Supporting answer:

In this problem, we are given an exponential function with an initial value of f(2) = 3 and a doubling time of 5. The doubling time represents the time it takes for the function to double its value. We can use the general form of an exponential function, f(x) = a * (2^(x/d)), to find the value of f(27).

Substituting the given values, we have 3 = a * (2^(2/5)). To solve for a, we divide both sides of the equation by (2^(2/5)): a = 3 / (2^(2/5)).

Now, we can substitute the value of a into the exponential function to find f(27). By plugging in x = 27, we get f(27) = (3 / (2^(2/5))) * (2^(27/5)). Evaluating this expression gives us f(27) = 096.

Therefore, the value of f(27) is 096, which is the answer.

In summary, the exponential function f with f(2) = 3 and a doubling time of 5 results in f(27) = 096.

The approximate real rate of interest is 4.86% and the exact real rate of interest is 4.98% is the correct naswer.

Real Rate of Interest: Real rate of interest is the actual interest earned or paid on an investment or loan, irrespective of the impact of inflation. It can be calculated by subtracting the rate of inflation from the nominal rate of interest. Therefore, the nominal rate of interest adjusted for inflation gives us the real rate of interest.

Approximate Real Rate of Interest: By using the formula Real rate = (1 + nominal rate) / (1 + inflation rate) - 1Real rate = (1 + 6.4%) / (1 + 1.5%) - 1

Real rate = 0.0486 or 4.86%

Thus, the approximate real rate of interest is 4.86%.

Exact Real Rate of Interest: The exact real rate of interest can be calculated using the Fisher effect formula that is: Real Rate = [(1+ nominal rate) / (1 + inflation rate)] - 1Real Rate = [(1 + 6.4%) / (1 + 1.5%)] - 1

Real Rate = 0.0498 or 4.98%

Thus, the exact real rate of interest is 4.98%.

In conclusion, the approximate real rate of interest is 4.86% and the exact real rate of interest is 4.98%.

The clinic should hire at least 7 doctors in order to serve 122 patients per day.

To determine how many doctors the clinic should hire in order to serve 122 patients per day, we need to calculate the number of patients each doctor can see within their working hours.

Let's start by calculating the total number of minutes each doctor works per day. Since each doctor works 8 hours per day and there are 60 minutes in an hour, the total minutes worked by a doctor per day would be 8 hours × 60 minutes = 480 minutes.

Next, we need to find out how many patients a doctor can see within their working hours. Given that each patient requires an average of 27 minutes with a doctor, the number of patients a doctor can see per day would be 480 minutes ÷ 27 minutes per patient = 17.7778 patients.

Since we can't have a fractional number of patients, we need to round this number up to the nearest whole number to ensure that each patient gets the required attention. Therefore, each doctor can see approximately 18 patients per day.

To serve 122 patients per day, we divide the total number of patients by the number of patients each doctor can see per day: 122 patients ÷ 18 patients per doctor = 6.7778 doctors.

Again, we can't have a fractional number of doctors, so we need to round this number up to the nearest whole number. Therefore, the clinic should hire at least 7 doctors to serve 122 patients per day.

In summary, the clinic should hire at least 7 doctors in order to serve 122 patients per day.

Answer:

Fantasia's family's car is more fuel-efficient.

Step-by-step explanation:

Given that, Tiyleah's family's car is getting 40 miles per gallon, and Fantasia's family's car uses 7 liters per 150 km.

The comparison can be done by observing the distance traveled by the cars in an equal amount of fuel. The car which covers more distance in an equal amount of fuel is more fuel-efficient.

First, convert the given units to have the same unit of measurement,

As 1 gallon =3.7854 liters and 1 mile = 1.609344 km

So, 40 miles =40 x 1.61=64.40 km

Now, The distance covered by Tiyleah's family's car is 64.40 km in 3.7854 liters.

So, the distance covered by Tiyleah's family's car in 1 liter of fuel is [tex]\frac{64.40}{3.7854}=17.01[/tex] km

In a similar way,

As Fantasia's family's car uses 7 liters per 150 km.

So, the distance traveled by Fantasia's family's car in 1 liter of fuel =150/7=21.43 km

Observe that, in 1 liter of fuel, Tyleah's family's car covered 17.01 km while Fantasia's family's car covered 21.43 km which is more.

Hence, Fantasia's family's car is more fuel-efficient.

Answer:

y = x/4 - 1/2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Write equation

x = 4y + 2

Step 2: Subtract 2 on both sides

x - 2 = 4y

Step 3: Divide both sides by 4

x/4 - 1/2 = y

Answer:

[tex]y=\frac{1}{4} x-\frac{1}{2}[/tex]

Step-by-step explanation:

To get slope-intercept form (y=mx+b), you have to solve this equation for y by using inverse operations. First, we can subtract by 2 on both sides to eliminate the +2 on the right side. This results in x-2=4y. To get y by itself, we can divide by 4 on both sides. This becomes (x-2)/4=y. To make this in slope-intercept form, we have to separate the terms into x/4 and -2/4. This is (x/4)+(-2/4)=y. We can reduce the second fraction to -1/2 and rewrite x/4 as 1/4x. The equation is y=1/4x-1/2.
