12345 [234]

Answer:

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

Step-by-step explanation:

We need to find mistake make in work below:

$(-2x^4)^4=-16x^{16}$

The mistake here is when we have even power, the negative sign gets positive i.e $(-a)^m=a^m$ if m is even

so, in our case it would be:

$(-2x^4)^4=16x^{16}$

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

Convert the following numbers of calories or

kap26 [50]

Answer:

32.823 kJ
190.4 kJ
260.00 kJ
180.012 kJ

Step-by-step explanation:

The conversion factor for food energy or thermochemical calorimetry* is ...

1 calorie = 4.184 J

1000 calorie = 4.184 kJ

__

a. 7845 cal = 7845·4.184 J = 32,823 J = 32.823 kJ

b. 4.55·10^4 cal = 4.55·10^4·4.184 J = 1.904·10^5 J = 190.4 kJ

c. 62.142 kcal = 62.142·4.184 kJ = 260.00 kJ

d. 43,024 cal = 43,024·4.184 J = 180,012 J = 180.012 kJ

_____

* The thermochemical calorie is defined in terms of the heat capacity of water. An international calorie of 4.1868 J is defined in terms of energy, without respect to the heat capacity of water.
