Answer:

The minimum umber of multiplication operations needed to compute is 1242.

Explanation:

Solution

Given that:

Now,

(A1*(A2*A3))*(A4A5)

Thus

A2*A3 = 7*30*2 = 420 operations. It will create 7*2 matrix.

A1*(A2*A3) = 3*7*2 = 42 operations. It will create 3*2 matrix

A4*A5 = 2*10*30 = 600 Operations. It will create 2*30 matrix.

(A1*(A2*A3))*(A4A5) = 3*2*30 = 180 operations. It will create 3*30 matrix

Hence

The total number of multiplications are is given below

420+42+600+180 = 1242

Complex calculations show that if the universe is geometrically flat, we should observe the greatest temperature differences bet

Rufina [12.5K]

Answer:

Answer is 1 degree.

Explanation:

W MAP stands for Wilkinson Anisotropy Probe which was working from 2001 to 2010 .It usually measured the temperature differences.Big Bang was a partnership with NASA and Princeton University. So if universe is geometrically flat we should observed that temperate between patches are separated by 1 degree.Because Universe is oval shape and contain 360 angular shape but if it goes flat we can see the patches at very low distance that is 1 degree.

Consider the two relations with their schemas as listed below: Employee(name, empID, birthDate, gender, address, phone) TaxAccou

Allushta [10]

Answer:

CREATE TABLE TaxAccount (

Name int NOT NULL,

SSN int NOT NULL,

empID int FOREIGN KEY REFERENCES employee(empID),

federalDeductionAmt int NOT NULL,

stateDeductionAmt int NOT NULL,

ficaDeductionAmt int NOT NULL

);

Explanation:

TaxAccount table will use the primary key of employees table 'empID' which will serve as foreign key in TaxAccount table.

Therefore TaxAccount table will look like this:

CREATE TABLE TaxAccount (

Name int NOT NULL,

SSN int NOT NULL,

empID int FOREIGN KEY REFERENCES employee(empID),

federalDeductionAmt int NOT NULL,

stateDeductionAmt int NOT NULL,

ficaDeductionAmt int NOT NULL

);

Write the definition of a function divide that takes four arguments and returns no value . The first two arguments are of type i

likoan [24]

Answer:

The following function definition is from C++ programming language.

//define function with arguments

void divide (int numerator, int denominator, int *quotient, int *remainder)

{

*quotient = (int) (numerator/denominator);

*remainder = numerator % denominator;

}

Explanation:

Here, we define a void data type method "divide()" with four arguments in which first two arguments are integer type variables "numerator" and "denominator", next two are pointer type variables "quotient" and "remainder".

After that, we divide the first two integer variables and save result in "*quotient" then, we again use these variables for modulation and save result in "*remainder".
