Multiply. Write your answer in scientific notation. (4.3 x 1012) (3.4 x 107)
1.462 x 1020
1.462 * 1019
1.462 * 1084
1.462 * 1085

  1.462 × 10^20

Step-by-step explanation:

Multiplication proceeds in the usual way. The rules of exponents apply. A final exponent adjustment is needed to put the number in scientific notation form. (Your calculator can do all of this for you.)

  (4.3×10^12)(3.4×10^7) = (4.3×3.4)×(10^12×10^7) = 14.62×10^(12+7)

  = 14.62×10^19

  = (1.462×10)×10^19 = 1.462×10^(1+19)

  = 1.462×10^20

The rule of exponents used is ...

  (a^b)(a^c) = a^(b+c)

I find it works well to estimate whether the product of the mantissas will be more than 10, then make adjustments to exponents before the multiplication:

  (4.3×10^12)(3.4×10^7) = (4.3×10^12)(0.34×10^8) = 1.462×10^(12+8)

  = 1.462×10^20

50=33x+22

step-by-step explanation:

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
