The length and the weight of the 12 pipe is found as 42 meters and 74.23 kg

As, per the given question;

For, the seven pipes, the length is 24.5m.

7 pipes ---------> 24.5 m.

For the one pipe, use unitary method for solving;

Divide the equation by 7.

1 pipe -------->24.5/7 m.

For 12 pipes, multiply with 12 on both sides.

12 pipes --------> 24.5×12/7 m.

12 pipes --------->  42 m.

Thus, the length of the 12 pipes is 42 meters.

Now, calculate the weight.

For, the seven pipes, the weight is 43.3 kg.

7 pipes ---------> 43.3 kg.

For the one pipe, use unitary method for solving;

Divide the equation by 7.

1 pipe -------->43.3 kg./7

For 12 pipes, multiply with 12 on both sides.

12 pipes --------> 43.3 kg×12/7

12 pipes --------->  74.23

Thus, the weight of the 12 pipes is 74.23 kg.

As per the given model for number of students given as a function of time since 1986 and relevant since 2000 , the number of students in 2010 is 14.67 millions.

As given,

Number of students given by formula

N =-0.033t² +0.46t +13.37

N =enrollments of students in millions

t =time

Relevant since 2000 we have to calculate N(10) ,it means after 10 years that is 2010

N(10) =-0.033×(10)² +0.46×10 +13.37

         =-3.3 +4.6 +13.37

         =14.67 millions

Therefore, number of students in 2010 is 14.67 millions is the correct option for the given model.

The complete question is :

One model for the number of students enrolled in U.S. Public high schools as a function of time since 1986 is  the formula below

The volume of the parallelepiped with adjacent edges PQ, PR, and PS is 24 cubic units.

Six parallelograms come together to form a three-dimensional shape called a parallelepiped (the term rhomboid is also sometimes used with this meaning). It is comparable to a parallelogram in the same way that a cube is comparable to a square. In Euclidean geometry, the four concepts—parallelepiped and cube in three dimensions, parallelogram, and square in two dimensions—are specified; however, only parallelograms and parallelepipeds exist in the setting of a more generic affine geometry, where angles are not discriminated.

There are three similar descriptions of a parallelepiped:

We have been that  p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), and s(3, 6, 1) are the adjacent edges of parallelepiped

PQ = Q-P = <6,3,4>

PR = R-P = <3,3.-1>

PS= S-P = <5,5,1>

[ PQ PR PS] = [tex]\begin{vmatrix}6& 3 & 4 \\ 3& 3 &-1 \\ 5 & 5 & 1 \\ \end{vmatrix}\\ \notag&& \\[/tex]

When Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800as annual income then the amount invested at 11% is $20000

Given,

The total amount Mardi received = $60000

She invested part at 11% and deposited the remainder in tax-free bonds at 12%.

Annual income from the investment = $6800

Consider the part of money invested at 11% as x

Then the equation will become

(60000-x)0.11+0.12x =6800

6600-0.11x+0.12x =6800

0.01x+6600=6800

0.01x=200

x= $20000

Hence, when Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800 as annual income then the amount invested at 11% is $20000

The solutions of the absolute value equation are x = −99 and x = 45.

Here we have the absolute value equation:

| (1/3)*x + 9| - 3 = 21

First, we can add 3 in both sides so we get:

| (1/3)*x + 9| = 21 + 3 = 24

This can be decomposed into two equations, we will get:

(1/3)*x + 9 = 24

(1/3)*x + 9 = -24

Solving these two we can get the two solutions.

The first one gives.

(1/3)*x = 24 - 9 = 15

x = 3*15 = 45

The second one gives:

(1/3)*x = -24 - 9 = -33

x = 3*-33 = -99

The solutions are x = −99 and x = 45.

As you increase the input number size(increase the o. of bits) the simulator is going to perform more calculation to get the value of newly added bits by calculating 2^n (for nth bit!) and hence the running time complexity will increase exponentially .

Electronic components such as resistors, transistors, capacitors, inductors, and diodes are connected by conductive wires or traces that allow electric current to flow between them. It is a specific kind of electrical circuit, and in order for a circuit to be called electronic rather than electrical, there usually needs to be at least one active component present. Signals may be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of components and wires.

Although discrete components can be assembled into circuits and connected by single wires, it is now far more typical to use photolithographic processes to make interconnections on laminated substrates and solder the individual components to these linkages.
