Answer:

Option A sin(A)=\frac{9}{15}

Step-by-step explanation:

we know that

tan(A)=sin(A)/cos(A)

Solve for sin(A)

sin(A)=tan(A)cos(A)

we have

tan(A)=\frac{9}{12}

cos(A)=\frac{12}{15}

substitute

sin(A)=\frac{9}{12}(\frac{12}{15})

sin(A)=\frac{9}{15}

Let X is the random number Erik thinks of, and Y is the random number Nita thinks of.
Both X and Y are in the range from 0 to 20.
<span>X<=20
Y<=20
If the difference between their two numbers is less than 10, then Erik wins.
The difference between the two numbers can be written X-Y, or Y-X depending on which number (X or Y) is greater. But we do not know that. In order not to get negative value, we calculate absolute value of X-Y,  written |X-Y| which will give positive value whether X is greater than Y or not.
If |X-Y|<10 Erik wins.

Jada created the two-way table below to describe the performance of her basketball team this season.
kramer
To answer the question, all the statements must be analyzed with the data presented in the table.
 From the table we get that the team played 16 games at home and 11 games away from home.
  In total, they played 27 games.
 Of the 16 games at home, the team won 6. Then, the proportion of games won at home is:
 6/16 = 0.375.
  Of the 11 games away from home, the team won 3. Then the proportion of games won away from home is:
  3/11 = 0.272.
  0.375 is not twice 0.272.
  Then the first statement is incorrect.

 The ratio of games won at home is 6/16 = 3/8. Therefore, the second statement is incorrect. The team does not win 3/5 of the games at home.
 The total number of games won is 9 and the total number of games is 27.
 So, the third statement is incorrect. The team does not win half of the games.
 The fourth statement is true. The team played 27 games

 The fifth statement is false because the team won more than 6 games. They won 3 games away from home and 6 games at home

 Finally, the sixth statement is correct, because the team lost 10 games at home and 8 away from home. However, the PERCENTAGE of games lost away from home is greater than the PERCENTAGE of games lost at home. Therefore, it is more likely that the team loses when playing away from home.

Phoenix [80]

Answer:

- 2x^5+ 0x^4 +  \frac{x^3}{2} +0x^2+\frac{x}{4}  + 1

Step-by-step explanation:

Given

\frac{x}{4} - 2x^5 + \frac{x^3}{2} + 1

Required

The standard form of the polynomial

The general form of a polynomial is

ax^n + bx^{n-1} + cx^{n-2} +........+ k

Where k is a constant and the terms are arranged from biggest to smallest exponents

We start by rearranging the given polynomial

- 2x^5+ \frac{x^3}{2} +\frac{x}{4}  + 1

Given that the highest exponent of x is 5;

Let n = 5

Then we fix in the missing terms in terms of n

- 2x^5+ 0x^{n-1} +  \frac{x^3}{2} +0x^{n-3}+\frac{x}{4}  + 1

Substitute 5 for n

- 2x^5+ 0x^{5-1} +  \frac{x^3}{2} +0x^{5-3}+\frac{x}{4}  + 1

- 2x^5+ 0x^{4} +  \frac{x^3}{2} +0x^{2}+\frac{x}{4}  + 1

Hence, the standard form of the given polynomial is - 2x^5+ 0x^4 +  \frac{x^3}{2} +0x^2+\frac{x}{4}  + 1
