Answer:

Width is 5 cm

Step-by-step explanation:

Since we know that the width is 25 meters, and the scale we are using is 5 meters = 1 cm, we can divide 25 by 5 to find the scaled measurement.

25/5 = 5cm

Answer:

The slope-intercept form is y =  \(-\frac{3}{4}\) x + 8 ⇒ B

Step-by-step explanation:

The slope-intercept form of the linear equation is:

y = m x + b, where

From the given in the question

∵ The slope of the line is \(-\frac{3}{4}\)

∴ m =  \(-\frac{3}{4}\)

→ Substitute its value in the form of the equation above

∴ y =  \(-\frac{3}{4}\) x + b

→ To find b substitute x and y by the coordinates of any point on the line

∵ The line passes through the point (8, 2)

∴ x = 8 and y = 2

∵ 2 =  \(-\frac{3}{4}\) (8) + b

∴ 2 = -6 + b

→ Add 6 to both sides to find b

∴ 2 + 6 = -6 + 6 + b

∴ 8 = b

→ Substitute the value of b in the equation above

∴ y =  \(-\frac{3}{4}\) x + 8

∴ The slope-intercept form is y =  \(-\frac{3}{4}\) x + 8

The values of a, b, and r in the circle equation are a = 0 b = -5 and r = 3

The center of the circle is (a, b) = (0, -5).

We know that the diameter of the circle is 6 units, which means the radius is half of the diameter, or 3 units.

Using the standard equation of the circle, we can substitute the values we know and solve for r:

(x - 0)² + (y - (-5))² = 3²

x² + (y + 5)² = 9

So, the values of a, b, and r are:

a = 0

b = -5

r = 3

Step-by-step explanation:

evaluate f(- 3) by substituting x = - 3 into f(x)

f(- 3) = 3(- 3)² - (- 3) + 5 = 3(9) + 9 + 5 = 27 + 14 = 41

evaluate f(4) by substituting x = 4 into f(x)

f(4) = 3(4)² - 4 + 5 = 3(16) + 1 = 48 + 1 = 49

Answer:

x - 6

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Note that x is opposite to the given angle and we are also given the hypotenuse.

Since we have an angle and the side opposite to it and the hypotenuse, we can use the sine ratio. Recall that:

\(\displaystyle \sin \theta =\frac{\text{opposite}}{\text{hypotenuse}}\)

The opposite side is x, the hypotenuse is 15, and the angle is 53. Substitute:

\(\displaystyle \sin 53^\circ = \frac{x}{15}\)

Solve for x:

\(x=15\sin 53^\circ\)

Use a calculator (make sure you're in Degrees Mode!). Hence:

\(x=11.9795...\approx 12\)

A person can save $1,200 - $300 = $900 with an HMO if they had ten physical therapy sessions costing $150 each.

A person with an HMO (Health Maintenance Organization) can save a significant amount of money on physical therapy sessions compared to someone with a health insurance policy. Let's calculate the savings a person would have with an HMO for ten physical therapy sessions costing $150 each.

With an HMO, the cost per visit for physical therapy is $30. Therefore, the total cost of 10 physical therapy sessions would be 10 x $30 = $300.

On the other hand, with a health insurance policy, after a deductible of $600, the policy pays 80% of the physical therapy costs. Since each session costs $150, the total cost for ten sessions would be 10 x $150 = $1,500.

The person would have to pay the deductible of $600, which means the insurance will cover 80% of the remaining cost. Therefore, the person will pay $600 (deductible) + $900 (20% of the cost) = $1,200.

In comparison, with an HMO, the person would only have to pay $300 for the ten sessions.

Therefore, a person can save $1,200 - $300 = $900 with an HMO if they had ten physical therapy sessions costing $150 each.

Step-by-step explanation:

80 X 20 = 16 questions answered correctly.

A type I error occurs when a researcher mistakenly rejects a true null hypothesis. In other words, it is a false positive result. Let's break down what happens in a type I error:

1. The researcher starts with a null hypothesis, which assumes that there is no significant relationship or effect between the variables being studied.

2. To test the null hypothesis, the researcher collects data and performs statistical analysis.

3. In a type I error, the researcher incorrectly concludes that there is a significant relationship or effect when, in fact, there is none.

4. This error can happen due to various reasons, such as sample size, random chance, or flaws in the experimental design.

To avoid type I errors, researchers typically set a predetermined significance level (often denoted as α) before conducting the study. The significance level represents the probability of making a type I error. By setting a lower significance level, such as α = 0.05, researchers aim to reduce the chances of mistakenly rejecting the null hypothesis.

In the context of the given question, if the researcher is trying to reduce error and avoid a type I error, it means they want to minimize the risk of incorrectly inferring findings to another practice setting. This would increase the confidence that nurses have in applying the research findings to their own work.

Answer:

Step-by-step explanation:

Start by breaking up the question into parts:'always an odd number' . An even number is any number divisible 2 e.g. 2n, an odd number is always 1 higher or lower than an even number e.g. 2n+1 or something similar. Getting an answer at the end of working of this form will prove the theory'any two consecutive integers' means two numbers that are next to each other on the number line.To prove this, we can do this in terms of n i.e. n and n+1'the squares' square the two terms we have just written down to give n2 and (n+1)2The 'sum of the squares' tells us to add these two parts together. We would then hope to work through this and get something similar to the idea of 2n+1 or something similarn2+(n+1)2=2n2+2n+1=2(n2+n) +1. The first part of this is even because it is divisible by 2. By adding 1 it must become odd.

Answer: Every even number can be expressed in the form (2n) where n is an integer. So we have an even number, 2n, and an odd number, 2m+r. Adding them together we get 2n + 2m + r, which can be expressed as 2 (n+m) + r.

The value of the integral ∫^3_1 (5e^x - 2) dx is 5e^3 - 5e - 4. To evaluate the integral ∫^3_1(5e^x − 2) dx, we can use the properties of integrals, specifically the linearity property.

The linearity property states that the integral of a sum or difference of functions is equal to the sum or difference of their individual integrals.

The antiderivative of e^x is e^x itself. Therefore, we can evaluate this integral by taking the difference of the exponential function evaluated at the upper and lower limits of integration:

First, let's break down the integral into two separate integrals:

∫^3_1 (5e^x - 2) dx = ∫^3_1 5e^x dx - ∫^3_1 2 dx

Now, we can evaluate each integral separately using the given result:

∫^3_1 5e^x dx = [5e^x]_1^3 = 5e^3 - 5e^1

∫^3_1 2 dx = [2x]_1^3 = 2(3) - 2(1)

Combining the results:

∫^3_1 (5e^x - 2) dx = (5e^3 - 5e^1) - (2(3) - 2(1))

= 5e^3 - 5e - 6 + 2

= 5e^3 - 5e - 4

Therefore, the value of the integral ∫^3_1 (5e^x - 2) dx is 5e^3 - 5e - 4.

John invests $2000 in a savings account with an annual interest rate of 4.5%, compounded monthly. A(t) = 2000(1.00375)^12t represents his balance after t years. A(1)-A(0) and A(2)-A(1) represent the interest earned in the first and second years, respectively. The average interest earned in the first and second years is 2000(1.00375)^12 - 2000 and 2000(1.00375)^24 - 2000(1.00375)^12, respectively.

A(1) - A(0) = 2000(1.00375)^12 - 2000(1.00) = 2000(1.00375)^12 - 2000. It represents the interest earned in the first year. A(1)-A(0)/1-0 = [2000(1.00375)^12 - 2000]/(1-0) = 2000(1.00375)^12 - 2000. It represents the average interest earned in the first year.

A(2)-A(1) = 2000(1.00375)^24 - 2000(1.00375)^12. It represents the interest earned in the second year. A(2)-A(1)/2-1 = [2000(1.00375)^24 - 2000(1.00375)^12]/(2-1) = 2000(1.00375)^24 - 2000(1.00375)^12. It represents the average interest earned in the second year.

The answer in A(2)-A(1) is larger. In the second year, the principal is larger, so the interest earned will be larger as well.

Answer:

width = 6k², length = 5k + 1

Step-by-step explanation:

Given

A = 30k³ + 6k² ← factor out 6k² from each term

   = 6k²(5k + 1)

Since area = width × length , then

width = 6k² and length = 5k + 1

Answer:

30k³ + 6k²

= 6k²(5k + 1)

because the width is equal to the greatest common monomial factor of 30k³ and 6k²

=> the width = 6k²
