Answer:

3.92 × 10 ^18

Step-by-step explanation:

(7 x 10^*9)(5.6 x 10^*8)

(7000000000)(560000000)

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

If the decimal is moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

What was i correct was the 2nd step since when multiplying -2x-6 it would be a positive 12 not a negative :)

Helen Ming receives a travel allowance of $220 each week from her company for time away from home. If this allowance is taxable

lina2011 [118]

Answer:

$33

Step-by-step explanation:

The travel allowance that Helen Ming receives is $220

The income tax rate is $15\%$

The amount she has to pay is calculated by multiplying the tax rate by the travel allowance.

$=\frac{15}{100}\times220$

We simplify to obtain

$=\frac{15}{10}\times22=33$

Therefore Helen Ming has to pay $33 form her benefit.

In Section 1.3 we saw that the autonomous differential equation m dv dt = mg − kv, where k is a positive constant and g is the a

Thepotemich [5.8K]

Answer:

$\lim_{t \to \infty} v = \frac{mg}{k}$

Step-by-step explanation:

Firstly its necessary to put the autonomous DE in its normal form to get

$\frac{dv}{dt} = g - \frac{kv}{m}$

To get the critical point we solve

g - $\frac{kv}{m} = 0$

$\frac{kv}{m} = g--> v = \frac{mg}{k}$

The critical point is $v = \frac{mg}{k}$

$\frac{dv}{dt} > 0 for v < \frac{mg}{k}$

and

$\frac{dv}{dt} < 0 for v > \frac{mg}{k}$

from the phase portrait we observe that the critical point

v = $\frac{mg}{k}$ is stable

$\lim_{t \to \infty} v = \frac{mg}{k}$
