5 - 2x^2 = -15 solve the question using inverse operations

Butoxors [25]

Answer:

x= √10 and x= -√10

Step-by-step explanation:

first look to isolate the term with the variable on one side

-5 +5 -2x² = -5 -15; subtract 5 from both sides(inverse of addition)

-2x² = -20; divide both sides by -2 (inverse of multiplication)

x² = 10; square root both sides (the inverse of raising to power of 2)

√x² =√10

x =±√10

A frequency distribution is a tabular summary of data showing the a. number of items in several classes. b. relative percentage

Viefleur [7K]

Answer:

The answer is a: Number of items in several classes.

Step-by-step explanation:

Frequency distributions are tables that represent the number of times a specific data, number object etc appears in a sample. So for example if we have this data

2,2,4,4,6,6,6,8,8,10

The frequency distributions is

Number frequency

2 2

4 2

6 3

8 2

10 1

The other options are identical (c and are the same as percentages can be expressed as fractions. Relative percentages or fractions are tables that express the weight that each category has in the entire data. An example for our data would be: (10 are the total number of obs)

Number Fraction/%

2 2/10 or 20%

4 2/10 or 20%

6 3/10 or 30%

8 2/10 or 20%

10 1/10 or 10%

Write (4√81)^6 in exponential form.

Sauron [17]

Answer:

Step-by-step explanation:

$(4\sqrt{81})^{6} = (4*\sqrt{9*9} )^{6}\\\\=(4*9)^{6}\\\\=(2^{2}*3^{2})^{6}\\\\=[(2*3)^{2}]^{6}\\\\=(6)^{2*6}\\\\=6^{12}$

Exponent Laws:

$(a^{m}*b^{m}) = (a*b)^{m}\\\\(a^{m})^{n}=a^{m*n}$

In 2011 Clayton Kershaw earned $500,000 pitching for the LA Dodgers. In 2019, his salary was $31,000,000. Answer the three parts

zvonat [6]

Answer:

A. $15,625 per game

B. $1,107,142.86 per game

C. he earned $607,142.86 more per game in 2019 than he did for the entire 2011 season

Step-by-step explanation:

His salary in 2011 = $500,000

His salary in 2019 = $31,000,000

A) Kershaw pitched in 32 games in 2011. What was his salary per game in 2011?

Kershaw's salary per game = Total salary / Total number of games

= $500,000 / 32 games

= $15,625 per game

B) He pitched in 28 games in 2019. What was his salary per game in 2019? Round to the nearest cent.

Kershaw's salary per game = Total salary / Total number of games

= $31,000,000 / 28 games

= $1,107,142.8571428

To the nearest cents

= $1,107,142.86 per game

C) Did he earn more per game in 2019 than he did for the entire 2011 season?

$1,107,142.86 per game - $500,000

= $607,142.86

Yes, he earned $607,142.86 more per game in 2019 than he did for the entire 2011 season
