Since the family rents a cottage for 7 days, 79.95 dollars each day, we multiply 79.95 by 7 and get 559.65. Since the question asks about how much does the family pay, we round 559.65 to get $560.

A denotes an mn matrix. Determine whether the statement is true or false. Justify your answer. The row space of AT is the same as the column space of A.
Answers
Answer: true
Step-by-step explanation:
For an m*n matrix, the column space of A will be a space formed by the lineal combination of all the columns of A.
column space = a1*c1 + a2*c2 + ...
where a1, a2, ... are scalars, and c1 is the vector of column 1.
Then we should write:
Column space = a1*(A₁₁, A₂₁, A₃₁, ...) + a2*(A₁₂, A₂₂, A₃₂, ...) + ...
Now, the transpose is defined as:
[At]₁₃ = A₃₁
Here i used the element with subindex 3 and 1, but is the same for every subindex.
Notice that if A is m*n, then [At] is n*m
Now, the row space of [At] will be, same as before.
Row space = b1*r1 + b2*r2 + ...
Where b1, b2, ... are scalars and the r's are the vector of each row.
= b1*( [At]₁₁ , [At]₁₂, [At]₁₃, ...) + b2*([At]₂₁, [At]₂₂, [At]₂₃, ...) + ...
Now we replace each term of the transpose by the associated element in the original matrix.
= b1*( A₁₁, A₂₁, A₃₁, ...) + b2*(A₂₁, A₂₂, ...) + ....
If we take:
b1 = a1, b2 = a2, b3 = a3, ...
We will have that the row space of [At] is the same as the column space of A.

If Mrs.Burks spent 3.87 on grapez at kroger and bought 3.05 pounds,how much was each pound
Answers
Answer:
1.26885245902 or rounded to $1.27 per pound.
Step-by-step explanation:
you can just divide 3.87/3.05 to see how much each pound costed. if you needed to round to the nearest cent, you would round up to 1.27.... or if not, keep it at 1.26885245902.
then to check your work, you can just multiply (1.26885245902) by (3.05) to get the total amount she had spent.

1) Is the solution to -2.7 + x= -3.5 positive or
negative.
Answers
Answer:
positive because two negatives make a positive and the answer is not positive.
The solution of the expression -2.7 + x =-3.5 is -0.8 and is negative.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is -2.7 + x= -3.5. The value of x will be calculated as,
-2.7 + x =-3.5
x = -3.5 + 2.7
x = -0.8
Therefore, the solution of the expression -2.7 + x =-3.5 is -0.8 and is negative.
