Answer:

  8.5 years

Step-by-step explanation:

You want to know the number of years until 18500 depreciates to 9100 at the rate of 8% per year.

The depreciation rate given as a percentage of current value tells you the depreciation is exponential. The formula will be ...

  value = (initial value) × (1 - (depreciation rate))^t

where the rate is "per year" and t is in years.

  value = 18500·(1 -0.08)^t

  9100 = 18500·0.92^t . . . . fill in the value of interest

  9100/18500 = 0.92^t . . . . divide by 18500

  log(91/185) = t·log(0.92) . . . . take logarithms

  t = log(91/185)/log(0.92) ≈ -0.3081/-0.03621 ≈ 8.509

It will be about 8.5 years until the value is $9100.

We find it fairly easy to locate an x-intercept, so we wrote the equation in the forms that makes the x-intercept the solution.

The 99% confidence limit will be option B which is (45, 55)

90% confidence limits for the population mean are (46,54)

mean = 46+54 / 2 = 50.

the margin of error E = 54-46/2 = 4

For 90% Confidence Z- Critical value is = 1.645

But the margin of error

E = ZS/√n

4=(1.645)S/√n

S/√n = 4 / 1.645

= 2.4316

For 95% confidence Z-critical value is 1.96

A 95% confidence interval is = mean ± E

(50 ± 1.96) S/√n = (50 ± 1.96)×2.4316

= 50+ 4.7660

= 45.2340, 54.7660

= (45, 55)

Hence the correct option is B which is (45, 55) as the 99% confidence limit.

Step 1: Suppose, for the sake of contradiction, that there are integers A and B such that A2 = 3B2 + 2015. Let N = A2. Then, N ≡ 1 (mod 3).

Step 2: By the Legendre symbol, since (2015/5) = (5/2015) = -1 and (2015/67) = (67/2015) = -1, we know that there is no integer k such that k2 ≡ 2015 (mod 335).

Step 3: Let's consider A2 = 3B2 + 2015 (mod 335). This can be written as A2 ≡ 195 (mod 335), which can be further simplified to N ≡ 1 (mod 5) and N ≡ 3 (mod 67).

Step 4: However, since (2015/5) = -1, it follows that N ≡ 4 (mod 5) is a contradiction.

Therefore, there are no integers A, B such that A2 = 3B2 + 2015.

a) Approximately 22.938 billion pounds of aluminum were shipped in 2003.

b)Approximately 23.946 billion pounds of aluminum were shipped in 2009.

To find the total net shipments of aluminum in a given year, we need to substitute the corresponding value of x into the equation g(x) = 15.3 + 2.889 ln(x + 1).

Given:

x = 0 corresponds to 1990

a) To find the total net shipments of aluminum in 2003, we need to find the value of x that corresponds to that year. Since x = 0 corresponds to 1990, we can calculate the value of x for 2003:

x = 0 + (2003 - 1990) = 13

Substituting x = 13 into the equation:

g(13) = 15.3 + 2.889 ln(13 + 1)

Using a calculator, we can evaluate this expression:

g(13) ≈ 15.3 + 2.889 ln(14) ≈ 15.3 + 2.889 * 2.639 ≈ 15.3 + 7.638 ≈ 22.938

Therefore, approximately 22.938 billion pounds of aluminum were shipped in 2003.

b) To find the total net shipments of aluminum in 2009, we need to find the value of x that corresponds to that year. Since x = 0 corresponds to 1990, we can calculate the value of x for 2009:

x = 0 + (2009 - 1990) = 19

Substituting x = 19 into the equation:

g(19) = 15.3 + 2.889 ln(19 + 1)

Using a calculator, we can evaluate this expression:

g(19) ≈ 15.3 + 2.889 ln(20) ≈ 15.3 + 2.889 * 2.995 ≈ 15.3 + 8.646 ≈ 23.946

Therefore, approximately 23.946 billion pounds of aluminum were shipped in 2009.

The commission is calculated as 12% of the portion of the weekly revenue that is over $1000. So, to calculate the commission, we subtract $1000 from the weekly revenue r, and then multiply the result by 0.12. The fixed salary of $500 is then added to the commission to get the total weekly salary.

Step-by-step explanation:

The formula that describes how the salesman's weekly salary s depends on his weekly revenue r is:

s = $500 + 0.12(r - $1000)

In this formula, s represents the salesman's total weekly salary, which includes both the fixed salary of $500 and the commission based on his weekly revenue. r represents the salesman's weekly revenue.

The commission is calculated as 12% of the portion of the weekly revenue that is over $1000. So, to calculate the commission, we subtract $1000 from the weekly revenue r, and then multiply the result by 0.12. The fixed salary of $500 is then added to the commission to get the total weekly salary.

Yes, the connection between the semimajor axis and an orbit's period varies as the eccentricity of the orbit changes.

In geometry, the eccentric definition is the distance from any point on a conic section to the focus divided by the perpendicular distance from that point to the nearest directrix. In general, eccentricity aids in determining the curvature of a form. The eccentricity grows as the curvature lowers.

Here,

In general, an orbit's period is proportional to the square root of the semimajor axis multiplied by three. This connection, however, is only valid for circular orbits with zero eccentricity. When the eccentricity is larger than zero, the period of the orbit is still determined by the magnitude of the semimajor axis, but it is also determined by the form of the orbit as given by the eccentricity. The relationship between the semimajor axis and the period in this situation is not as straightforward as a proportionate relationship.

As a result, modifying an orbit's eccentricity modifies the connection between the semimajor axis and the period.

For the first question, the answer is option C) 172.  On day 1, Joe remembered all 200 words. On day 2, he remembered 10% fewer words than he did on day 1. This means he remembered 90% of the words he memorized on day 1.

90% of 200 is (90/100) x 200 = 180 words.
On day 3, Joe remembered 10% fewer words than he did on day 2. This means he remembered 90% of the words he memorized on day 2.
90% of 180 is (90/100) x 180 = 162 words.

The probability exactly two of the appeals were successful is 0.9536

We are given that 40% of first-round appeals were successful (The Wall Street Journal, October 22, 2012), and suppose ten first-round appeals have just been received by a Medicare appeals office.

This situation can be represented through Binomial distribution as;

\(P(X=r)={}^{n}C_{r}(p)^r(1-p)^r\) where \(x=0,1,2,3.....\)

where,  n = number of trials (samples) taken = 10

            r = number of success

            p = probability of success which in our question is % of first-round

                  appeals that were successful, i.e.; 40%

So, here X ~ Binom(n=10 , p=0.40

Probability that at least two of the appeals will be successful = P(X>=2)

   P(X >= 2) = 1 - P(X = 0) - P(X = 1)

                    = 1 - \(^{10}C_{0}(0.40)^0(1-0.40)^{10-0}-^{10}C_{1}(0.40)^1(1-0.40)^{10-1}\)

                     = 1 - 0.00605 - 0.0403

The equation is 2x - 3 = 5x + 21. Solving for "x" gives the solution of x = -8.The equation for this issue is as follows:

2x - 3 = 5x + 21

where "x" stands for the unidentified number.

We can separate the variable term on one side of the equation and the constant terms on the other side in order to solve for "x".

To begin, we can take away 2x from both sides to obtain:

-3 = 3x + 21

Then, we can take 21 away from both sides to get at:

-24 = 3x

Finally, multiplying both sides by 3 gives us:

x = -8

Consequently, x = -8 is the answer to the equation.

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ABC

Now , the first measure of angle = 55

The second measure of angle = 60

The angle of the first ∠A = 180 - ( first measure of angle + second measure of angle )
