Answer:
5.3× 10⁴= ?
Step-by-step explanation:
10⁴ can also be written as 10×10×10×10= 10000
so, 5.3 × 10000= 53000
3 is the remainder because the closest is 7 times 21 so it’s remainder 3
Answer:
Step-by-step explanation:
The exponential decay function is
where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:
which simplifies to
Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:
which simplifies a bit to:
so
v(t) = 8043.57
Subtract the totals and you get 223. Then divide 223/1538=14.5
Answer:
64 females
Step-by-step explanation:
4 females:5 males
