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

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
