Answer:

x = 4i - 1 or

x = 4i + 1

Step-by-step explanation:

(x+1)^2 = -4

x+1 = (+-)4i

x = +-4i - 1

Answer:

Area = 115 yards

Step-by-step explanation:

If we look at this as two rectangles, you can see that the area of one is going to be 10yd multiplied by 9yd, which gives us 90yd. The other smaller rectangle will be 6yd multiplied by 4yd, which gives us 24yd.

Now, add the two areas back together to get the area of the whole shape and you get A=115yd.

Answer:

g=4

Step-by-step explanation:

Move all terms not containing g to the right side of the equation.

-7g-2=-30

-7g=-28

g=-28/-7

g=4

hi ^^

---------

Here's your answer: g=4

-----------------------------------

Now the steps: Equation: −7g−2=−30

· Add 2 to both sides.

−7g=−30+2

· Add −30 and 2 to get −28.

−7g=−28

· Divide both sides by −7.

g=   −7 /−28

· Divide −28 by −7 to get 4.

g=4

Answer:

3.Events A and B are not independent because P(A|B) ≠ P(A).

Step-by-step explanation:

Given this information, which statement is true?

1.Events A and B are independent because P(A|B) = P(A).

2.Events A and B are independent because P(A|B) ≠ P(A).

3.Events A and B are not independent because P(A|B) ≠ P(A).

4.Events A and B are not independent because P(A|B) = P(A).

Solution:

Two events A and B are independent if A occurring does not change the probability of B. For independent events:

P(A ∩ B) = P(A) * P(B)

Hence: P(A/B) = P(A ∩ B) / P(B) = P(A) * P(B) / P(B) = P(A)

Let event A represent the probability that roger wins a tennis tournament and event B represent the probability that Stephan wins a tennis tournament.

Therefore:

P(A) = 0.45, P(B) = 0.4

The probability of Roger winning the tournament, given that Stephan wins, is 0. Hence, P(A/B) = 0

P(A/B) = P(A∩B) / P(B)

0 = P(A∩B) / 0.4

P(A∩B) = 0

The probability of Stephan winning the tournament given that Roger wins, is 0. Hence P(B/A) = 0

P(B/A) = P(B∩A) / P(A)

0 = P(B∩A) / 0.4

P(B∩A) = 0

Therefore since P(A∩B) = P(B∩A) =0, this means that event A and event B are mutually exclusive. That is both events cannot occur at the same time.

Events A and B are not independent because P(A|B) ≠ P(A).

Answer:

m=3/4

Step-by-step explanation:

first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)

we have the equation 4x+3y=9

subtract 4x from both sides

3y=-4x+9

divide by 3

y=-4/3x+3

perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1

so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1

(m is the slope value)

-4/3m=-1

multiply by -3/4

m=3/4

therefore the slope of the perpendicular line is 3/4

hope this helps!! :)

Using proportions, it is found that:

a. The equations are related to the stories as follows:

b. The parenthesis is because of the 10% reduction was applied over the value subtracted by $20.

c. The solutions are given as follows:

A proportion is a fraction of a total amount, and are used along with basic arithmetic operations such as multiplication or division to find the desired measures in the context of a problem.

One example of application of proportions is for percentage problems, as the decimal equivalent of the percentage, considering discounts or increases, is multiplied by the total amount to find the equivalent amount.

For the college class, we have that:

The equivalent amount is of 830 students, hence the equation is:

0.9x + 20 = 830

The solution is found as follows:

0.9x = 810

x = 810/0.9

x = 900.

Which is the size of the freshmen class in the previous year.

For the computer in the store, we have that:

This price is of 830, hence the equation is:

0.9(x - 20) = 830

The solution, which is the initial price of the computer, is found as follows:

x - 20 = 830/0.9

x = 20 + 922

x = 942.

Step-by-step explanation:

Answer:

10 m building in Patrick's drawing would be of  0.5 cm

Step-by-step explanation:

Scale of Patrick's drawing is

1 inch = 10 meters

or 2.54 cm = 10 meters

1 cm = 3.94 m

In case of  Squidward the scale is 2 cm = 40 meters or

1 cm = 20 meters

So a 10 m building in Patrick's drawing would be of

0.5 cm

Answer:

13.5

Step-by-step explanation:  

Given: Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters.  

To find: How tall is the hotel on Squidward’s drawing?  

Formula: Height of the building = y × tan x + measurer's height  

Solution: The height of the building is calculated by using the formula. y = distance of the measurer from the building. x = the angle measured from the clinometer.

Total number of people who play sports in the Algebra 2 class:

[tex]21 - 9 = 12[/tex]

If there are 10 students who play Basketball, there are 2 students who ONLY play Baseball. If there are 9 students who play Baseball, there are 3 students who ONLY play Basketball.

So the number of students who play BOTH sports is:

[tex]12 - 2 - 3 = 12 - 5 = 7[/tex]

If 7 from the 21 Algebra 2 class students play BOTH sports, the probability is:

Answer:

1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.

2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.  

Step-by-step explanation:

Answer:

1) Sometimes

2) Never

Step-by-step explanation:

1) you could have two angles add up to 180 degrees and one of them could be less than 90

example, x = 140° and y = 40°

2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Answer:

x = 38

∠P = 26º

Step-by-step explanation:

The sum of the angle in a triangle is 180

x + (x + 78) + (x - 12) = 180

Combine like terms

3x + 66 = 180

Subtract 66 from both sides

3x = 114

Divide both sides by 3

x = 38

-----------------------

∠P = x - 12

∠P = 38 - 12

∠P = 26º

Answer:

Step-by-step explanation:

(x+78)+(x-12)+x=180

3x+66=180

3x=114

x=38

P=26
