Answer:
The correct option is the last one (0,84 grams, because (5.04 × 1.67) × (10^23 x 10^-24) = 8.4168 x 10^-1))
Step-by-step explanation:
The first step is to think that you have to multiply the number of atoms for the weight of each atom.
When you work with scientific notation, you should solve the operation for numbers and for the ten base. In this case you solve 5.04 x 1.67 and then the product of the ten bases. For this product you have to sum the exponents of the ten base 23 + (-24) = -1.
Summarizing.... 5.04 x 10^23 x 1.67 x 10^-24 = (5.04 x 1.67) x (10^23x10^-24) ⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 8.4168 x 10^-1
⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 0,84168.
Answer:
-6
Step-by-step explanation:
The pattern here is that you substract 15 every time you move a number (left to right) , therefore: 9-15 = -6

Answer:
$44.10
Step-by-step explanation:
The sale price of the shoes is (1.00-0.40)($70), or $42.
The final price, including tax, is (1.00 + 0.05)($42), or $44.10.
Even means g(-x)=g(x)
replace x with -x and see if it simplifies to original functin
g(-x)=(-x-1)²+1
g(-x)=((-1)(x+1))²+1
g(-x)=(x+1)²+1
nope
g(x)=2x²+1
g(-x)=2(-x)²+1
g(-x)=2x²+1
yep
we are done
answer is 2nd one
