Solving Square Root Worksheet (x - k)^2 Part 2

Mathematics
1 answer:
sineoko [7]3 years ago
4 0

Answer:

4. x = 2 + 2sqrt(10/3), 2- 2sqrt(10/3)

5. No real solutions

x = 1 + 3sqrt(2) i, 1 - 3sqrt(2) i,

6. x = 1 + sqrt(2), 1 - sqrt(2)

Step-by-step explanation:

4. 3(x - 2)² = 40

(x - 2)² = 40/3

(x - 2) = +/- sqrt(40/3)

x - 2 = +/- 2sqrt(10/3)

x = 2 +/- 2sqrt(10/3)

5. -2(x - 1)² = 36

(x - 1)² = -18

A perfect square can never be negative for real values of x

(x - 1) = +/- i × sqrt(18)

x - 1 = +/- i × 3sqrt(2)

x = 1 +/- i × 3sqrt(2)

6. 4(x - 1)² = 8

(x - 1)² = 2

x - 1 = +/- sqrt(2)

x = 1 +/- sqrt(2)

stiks02 [169]

Answer:

The next time Mahnoor visits the restaurant, there is:

--31 % chance for country music

--47% chance of rock & roll

--22% chance of blues

Completed question;

Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. She found that the restaurant was playing country 11 times, rock & roll 17 times, and blues 8 times. Use the observed frequencies to create a probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Step-by-step explanation:

Given;

The number of times they were playing each type of music;

Country = 11 times

Roll = 17 times

Blues = 8 times

Total visits of Mahnoor = 11+17+8 = 36

Developing a frequency table and probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Probability = number of favourable outcomes ÷ total number of outcomes.

Music played  |  Frequency  |  Probability

country            |  11                 |  11/36 = .31 or 31%

rock & roll        |  17                |  17/36 = .47 or 47%

blues                |  8                 |  8/36 = .22 or 22%

The figure below has to be covered with multi-colored cloth. What is the area of the cloth in sq mm that is needed?
Georgia [21]

Answer:

26,250 sq mm^2

Step-by-step explanation:

First i cut the shape so its a rectangle on the top and there is a vertical rectangle. Then you find the lengths and to do that for the first rectangle(the horizontal one) you add 75, 75 and 75 to get the length. Then multiply 225(the sum of the 3 75s) by 75 (width) which gets you 16,875.

That is the area of the first rectangle

Now for the vertical rectangle you simply multiply the length and width, 75x125. That equals 9,375. Now add.

9375+16875= 26250!!!!
