1. Solve for BC using Law of Cosines. Round to the nearest tenth when necessary.

Answer:

Step-by-step explanation:

Given-: Y= -X+1  (1)

            3X-Y=3  (2)

we will put the value of Y from equation (1) in equation (2)

  3X-(-X+1)=3

   3X+X-1=3

   4X-1=3

Taking -1 to R.H.S

  4X=3+1

 4X=4

 X=4/4

 X=1

Now put the value of X in equation (1)

Y=-X+1

Y=-1+1

Y=0

So the option will be B (1,0)

a. The probability that both adults think most celebrities are good role models is 0.0359

b. The probability that neither of adults think that celebrities are good model is 0.6559.

P(adult think most celebrities are good role models) = 209 / 1100

Since the first selected adult is not replaced, there are 1099 total adults left.

P(second adult think most celebrities are good role models) = 208 / 1099

So, P(both adults think most celebrities are good role models) = 209 / 1100 * 208 / 1099

= 0.19 × 0.1893

= 0.0359

b) The probability that neither of adults think that celebrities are good model is,

P(Neither adult) = P(1st adult does not think)P(2nd adult does not think)

= ((1100 – 209)/1100)((1100 – 209– 1)/1099) =0.6559

The approximate distance around the outside of the circular field is the circumference = 172.7 feet and the correct option is B.

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π = 3.14).

We shall derive the approximate distance around the outside of the circular field by calculating for the circumference as follows:

Radius of the circular feild = 27.5

circumference of the circular feild = 2 × 27.5 feet × 3.14

circumference of the circular feild = 55 feet × 3.14

circumference of the circular feild = 172.7 feet.

Therefore, the approximate distance around the outside of the circular field is derived as the circumference which is equal to 172.7 feet.

Answer: A rational function is a function that is a fraction and has the property that both its numerator and denominator are polynomials.

Step-by-step explanation:

Using exponential function, the value of x that makes f(x) = g(x) is x = 6.7 (rounded to the nearest integer).

The value of x that makes f(x) = g(x) is approximately x = 76.

To solve this, you can set f(x) = g(x) and solve for x.

[tex]f(x)=400(0.90)^x\\g(x)=70(1.10)^x\\400(0.90)^x = 70(1.10)^x\\Divide both sides by 400 to get:\\(0.90)^x = (1.10)^x / (400/70)\\[/tex]

Take the logarithm of both sides and use the power rule:

[tex]x(log 0.90) = (log (1.10)) / (log (400/70))\\x = (log (1.10)) / (log (400/70)) / (log 0.90)\\x = 76.3 (round to the nearest integer)\\[/tex]

Therefore, the approximate value of x that makes f(x) = g(x) is x = 76.

To solve this, we can set the two equations equal to each other and solve for x.

[tex]f(x)=400(0.90)^x = 70(1.10)^x\\400(0.90)^x = 70(1.10)^x\\(0.90)^x = 70/400 (1.10)^x\\(0.90)^x / (1.10)^x = 70/400\\(0.90/1.10)^x = 70/400\\(0.81818)^x = 70/400\\[/tex]

Take the logarithm of both sides.

[tex]xlog(0.81818) = log(70/400)\\x = log(70/400) / log(0.81818)\\x = 6.7 (rounded to the nearest integer).[/tex]

The fifth term of the arithmetic sequence can be found to be 18.

There are two definitions for an arithmetic sequence. It is a "series where the differences between every two succeeding terms are the same" or "each term in an arithmetic sequence is formed by adding a fixed number (positive, negative, or zero) to its preceding term."

In this arithmetic sequence therefore, you can find the common difference to be:

Answer:

A. Stephanie correctly rewrote g(x) as a transformation of f(x), and she described the asymptotes of the two functions correctly.

Step-by-step explanation:

The statement is true because, g(x) = f(x) + 4 is indeed a transformation of f(x) by shifting the graph 4 units up, and because the horizontal asymptote is determined by the highest degree term in the function, which in this case is the same for both functions, so the two functions will have the same vertical asymptote, but the horizontal asymptote is determined by the leading coefficient which is different for both functions, so the two functions will have different horizontal asymptotes.

B) 1 1/2 batches

C) 10 batches

D) 1 2/3 batches

Step-by-step explanation:

A) A 1/4 goes into 1, 4 times so it would make 4 batches.

B) 1/4 = 2/8 so 3/8 = 1.5/4 and that would make 1.5 batches.

C) since 1 cup of sugar can make 4 batches, 2 cups can make 8 batches and 1/2 cup makes 2, so 8+2= 10 batches

D) 1/4=3/12 that means 5/12 = 1/4+1/6 and 1/6 divided by 1/4 = 2/3 so that means that it can make 1 2/3 batches.

To find the greatest possible price of the calculator, we can use the information given about the total sales.

We know that the total sales of the calculator on three days are $180, $414, and $306. We can assume that the calculator is sold at a single price p on all three days, and the total number of calculators sold is x, y and z respectively.

So, we can set up the following equation:

px = $180 (1)

py = $414 (2)

p*z = $306 (3)

From (1) and (2) we can say x < y and from (2) and (3) we can say y > z

so the greatest possible price of the calculator will be the one from equation (2)

p = $414 / y

Therefore, the greatest possible price of the calculator is $414 / y.

It is important to note that we don't know the actual numbers of calculators sold, but we know that y is greater than x and z, and that is why we can say that the greatest possible price of the calculator is $414 / y.
