A car’s value depreciates at a rate of 3.4% per year. The car was worth $30,000 when it was new.

Which equation could be used to determine when the car will be worth $18,500, where x is time in years?

A. 18500 = 30000 (0.034)^x
B. 18500 = 30000(0.966)^x
C. 30000 = 18500(0.34)^x
D. 30000 = 18500 (0.966)^x

Answers

It should be D.30000 = 18500

20m + on ?
Which expression is equivalent to 54n

Answers

Answer:

Choice A, 20(3n-m)

Step-by-step explanation:

First, lets combine like terms for the question 54n - 20m + 6n,

60n - 20m.

Next, lets rule out the choices that are visibly wrong. This includes Choice B, because it wouldn't equal what is above and Choice C, as it ignores unlike terms.

Now, it is down to Choices A and D. Let's use the distributive property to simplify these options.

Choice A:

20(3n-m)

60n-20m

Choice D:

20(m-3n)

20m-60m

With this, it can be concluded that the correct answer is Choice A since it equals 60n-20m, which is equal to the original question when like terms are combined.

Recall the experiment comparing patients 4 weeks after surgery for carpal

tunnel syndrome. The patients who had endoscopic surgery demonstrated

a mean pinch strength of 9.1 kg compared to 7.6 kg for the open- incision

patients.

4. What hypotheses would you test?

5. The P-value of the test was less than 0.05. State a brief conclusion.

Answers

Answer:

4. H0: u1= u2 Ha; u1≠ u2

5. The smaller value of p supports the null hypothesis.

Step-by-step explanation:

4. The null and alternate hypotheses are

H0: u1= u2 i.e there no difference between the mean pinch strengthof the two surgeries

against the claim

Ha; u1≠ u2 i.e there a difference between the mean pinch strengthof the two surgeries

It can be written like this as well

H0: u1 -u2= 0 i.e there no difference between the mean pinch strengthof the two surgeries

against the claim

Ha; u1 -u2≠ 0 i.e there a difference between the mean pinch strengthof the two surgeries

Part 5. The test having a p- value less than 0.05 tells that the null hypothesis cannot be rejected. Theres no evidence to reject the null hypothesis.

The smaller value of p supports the null hypothesis.

Answer:

a) [tex]x=\frac{y}{k}[/tex]

b) [tex]y=0.6k[/tex]

c) [tex]x=\frac{38.5}{k}[/tex]

Step-by-step explanation:

From the question we are told that:

[tex]y=38.5[/tex]

[tex]x=0.6[/tex]

Generally the equation for the directly proportional variable is mathematically given by

[tex]y \alpha x[/tex]

[tex]y=kx[/tex]

Where

[tex]K=proportionality\ constant[/tex]

The Formula in terms of x

[tex]x=\frac{y}{k}[/tex]

[tex]y=k(0.6)[/tex]

[tex]y=0.6k[/tex]

[tex]38.5=kx[/tex]

In circle D with m \angle CDE= 122m∠CDE=122 and CD=6CD=6 units, find the length of arc CE. Round to the nearest hundredth.

Answers

Answer:

12.78 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the question:

θ = 122°

r = 6 units

Therefore, the arc length =

2 × π × 6 × (122/360)

= 12.775810125 units

Approximately to the nearest hundredth = 12.78 units

Therefore, the length of arc CE is 12.78 units

Answers

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
