The vertex of this parabola is at (-2,-3). When the y-value is -2,the x-value is -5. what is the coefficient of the squared expression in the parabola's equation?

Answers

Answer 1
Answer:

Answer:

It is -3

Step-by-step explanation:

I just missed it and it told me the right answer and the dude before me made me get it wrong. APEX
Answer 2
Answer: Hello,

Vertex=(-2,-3)

Equation of the parabola is y=k(x+2)²-3
(-5,-2) is a point of the parabola
==>-2=k(-5+2)²-3==>3-2=k*9==>k=1/9

Equation is y=1/9* (x+2)² -3

The coefficient of the squared expression in the parabola's is 1/9

a chess player played 20 games total. if he won 2 of the games, what is the ratio of games he lost to games he won?

Answers

20-2=18\n\sf\nSo,~ he~ lost~ 18~ games.\n\ngames~ lost:games~ won\n\nThe~ ratio ~is \n18:2\n\nWhich~ can~ be~ simplified ~to\n9:1
1.       Find the ratio of the Chess player in where he played a total of 20 games and won 2 of the games.
Ratio is considered as the quantitative relationship between to numbers that show the value of both sides.
Now, in the chess game, there are 20 games in all and he won 2 games. To get the ratio of his lose and win, simply subtract 2 from 20
=> 20 -2 = 18
thus, the ratio of the chess game is
=> 18 : 2
=> 18 is the lose
=> 2 is the win.



In the first 42 Super Bowls, 0.16(repeating sign over 6) of the MVPs were running backs.a. What percent of the MVPs were running backs? Write the percent as a mixed number.

b. What fraction, in simplest form, of the MVPs were not running backs?

Answers

0.16 (repeating sing over 6) is a decimal number. It represents the running backs among the MVP.

1) It can be converted into its percentage form by multiplying it with 100%. 

0.1666 x 100% = 16.66%  of the MVP are running backs.

2) 1 - 0.1666 = 0.8334 is the decimal number for MVPs who were not running backs.

Its fraction form is 0.8334/1.000 or 83.34% of the MVPs were not running backs.

Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second

Answers


angle 1+ angle 2=180    supplementary angles add up to 180

angle 2=x     assign angle a variable

angle 1= 3x-38      find equation for first angle

3x+x-38=180      set both angles added together equal to 180

4x-38=180        combine like terms

4x=218        add 38 to both sides

x=54.5        divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38   plug back in and solve

angle 1= 125.5           


3x-38
x-2nd angle

3x-38+x=180
4x-38=180
4x=218
x=54.5

First angle 
3(54.5)-38
163.5-38
125.5

Which of the following shows the correct steps to find the value of 16 to the power of 1 over 4?16 to the power of 1 over 4 equals 2 to the power of 4 to the power of 1 over 4 equals 2 to the power of 4 multiplied by 1 over 4 equals 2
16 to the power of 1 over 4 equals 4 to the power of 4 to the power of 1 over 4 equals 4 to the power of 4 multiplied by 1 over 4 equals 4
16 to the power of 1 over 4 equals 2 to the power of 8 to the power of 1 over 4 equals 8 to the power of 8 multiplied by 1 over 4 equals 4
16 to the power of 1 over 4 equals 8 to the power of 2 to the power of 1 over 4 equals 2 to the power of 2 multiplied by 1 over 4 equals 8

Answers

Answer:

Option A is correct.

Value of 16 to the power of 1 over 4 equals to the power of 4 to the power of 1 over 4 equals 2 to the power of 4 multiplies by 1 over 4 equal 2.

Step-by-step explanation:

To find the value of: 16 to the power of 1 over 4.

16^{(1)/(4)}

we can write 16 as:

16 = 2 \cdot 2 \cdot 2 \cdot 2 = 2^4

⇒(2^4)^{(1)/(4)}

⇒(2)^{4 \cdot (1)/(4)}             [∴(a^n)^m = a^(nm)]

⇒2

Hence, the value of 16^{(1)/(4)} is, 2.

Therefore, the value of 16 to the power of 1 over 4 equals to the power of 4 to the power of 1 over 4 equals 2 to the power of 4 multiplies by 1 over 4 equal 2.

Ans.  16 to the power of 1 over 4 equals 4 to the power of 4 to the power of 1 over 4 equals 4 to the power of 4 multiplied by 1 over 4 equals 4
