What is 8.3 x 10^4 in standard form

83.000

Step-by-step explanation:

8.3 × 10⁴

= 8.3 × (10 × 10 × 10 × 10)

= 8.3 × (100 × 10 × 10)

= 8.3 × (100 × 100)

= 8.3 × 10.000

= 83.000

Conclusion:

The result of 8.3 × 10⁴ is 83.000

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
