Find the suggested determinants. Given [A] = [5 -4 3 -3]. Find the determinant of [A].

Answers

Answer:

-3

Step-by-step explanation:

For a 2 by 2 matrices such as B =  [a b c d], the determinant is expressed as;

ad - bc

Given the matrices

[A] = [5 -4 3 -3]

Determinant of A  = 5 (-3) - -4(3) (if you compare with the original matrices)

Determinant of A  = -15 + 12

Determinant of A  =-3

Hence the Determinant of A  is -3

Given that a = 7, b = 5 and c = 5.
Find the square root of
3a + 2b + c

Answers

Step-by-step explanation:

[tex]3a + 2b + c = 3(7) + 2(5) + 5 \\ = 21 + 10 + 5 \\ = 36 \\ \sqrt{3a + 2b + c} = \sqrt{36} \\ = 6[/tex]

The square root of 3a + 2b + c is 6.

What is square root?

The square root of a number is the factor that we can multiply by itself to get that number.

Now the given expression is,

3a + 2b + c

Now square root of 3a + 2b + c is given as,

√(3a + 2b + c)

Putting, a = 7, b = 5 and c = 5 in the given expression we get,

√(3a + 2b + c) = √(3*7 + 2*5 + 5)

Multiplying we get,

⇒ √(3a + 2b + c) = √(21 + 10 + 5)

Adding we get,

⇒ √(3a + 2b + c) = √36

Since, √36 = 6

Therefore,

⇒ √(3a + 2b + c) = 6

which is the required value of the square root.

Thus, The square root of 3a + 2b + c is 6.

Answers

D is the correct answer

The given histogram is Negatively skewed, and the mean is to the right of the median.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

For a symmetric histogram, the values of the mean, median, and mode are all the same and are all located at the center of the distribution.

A negatively skewed distribution is a type of distribution in which more values are concentrated on the right side of the distribution graph while the left tail of the distribution graph is longer

The data distributed where is the mean located in relation to the median is to the right side.

Hence, the given histogram is Negatively skewed, and the mean is to the right of the median.

A local park currently has 150.04 square meters of grassy area. The members of a community group have proposed the following changes to the way the park land is used.

Clearing dead trees and shrubs would allow for 37.51 square meters of additional grassy area.
Removing an unused picnic pavilion would allow for 82.70 square meters of additional grassy area.
Updating and expanding the playground would reduce the grassy area by 54.19 square meters.
How many square meters of grassy area would the park have if all of the community group's proposals were applied?

A.
66.02 square meters
B.
95.85 square meters
C.
216.06 square meters
D.
249.42 square meters

Answers

Answer: they would have 216.06 square meters of grassy area left in the park

Step-by-step explanation: if you start with 150.04 and add 37.51 by removing trees and shrubs you would have 187.55 and then if you added 82.70 more square feet by removing the unused Picnic pavilion you would have 270.25 square meters of grassy area. Then lastly is you update the playground by reducing 54.19 square meters ( 270.25-54.19) you would get left with 216.06 square meters of grassy area :)
