Which shows the expression below in simplified form? (2.4 × 1018) + (3.4 × 1015)

Mathematics
1 answer:
RUDIKE [14]3 years ago
7 0

Answer: 5894.2

Step-by-step explanation:

You'll want to follow PEMDAS to simplify this expression.

1.) P - Parentheses

2.) E - Exponents

3.) M - Multiplication

4.) D - Division

5.) A - Addition

6.) S - Subtraction

We'll start with what's inside the parentheses:

(2.4 × 1018) + (3.4 × 1015)

(2,443.2) + (3,451)

Now all you have to do is add the values together to get your answer!

2,443.2 + 3,451

5894.2

Which matrix is the product of a 3 × 3 identity matrix and the scalar 3?
Ludmilka [50]

Answer:

\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right]

Step-by-step explanation:

In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:

The 3x3 identity matrix is:

\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

Multiplying with scalar 3:

3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

The scalar will be multiplied by each element of the matrix.

Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:

\left[\begin{array}{ccc}3*1&0&0\\0&3*1&0\\0&0&3*1\end{array}\right] = \left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right]

So the resultant matrix will be a scalar matrix with 3 at diagonal positions..

If the rate of decrease for the partial pressure of N2H4 in a closed reaction vessel is 76 torr/h , what is the rate of change f
fiasKO [112]

The reaction is missing and it's ;

N2H4 + H2 ---> 2NH3

It asks for the total pressure too.

Answer:

A) Rate of change for NH3 = 152 torr/h

B) The total pressure in the vessel will remain the same.

Step-by-step explanation:

N2H4 + H2 ---> 2NH3

1 mole of N2H4 yields 2 moles of NH3.

From the question, the rate given for N2H4 is 76 torr/h.

Thus, The rate of change for NH3 will be = 2 x 76 = 152 torr/h

Now, on the reaction side, 1 mole of N2H4 reacts with 1 mole of H2. So we have 2 moles on the left hand side.

While on the product side, 2 moles of NH3 are produced.

So the total pressure will remain the same because for every 2 moles on the reaction side, 2 moles are gotten on the product side.

finlep [7]

Answer:

Slope=0.10

Interpretation: For every minute Olivia is in the cafe she is getting charged 10 cents

Step-by-step explanation:

The slope is a constant followed by a variable (a,x,b,z,etc...) So the only constant with a variable after it was the 10.

Hi! X = 2
Because 4 + 10 = 14. 16-14 = 2
x =2
Does this make sense?
