Scientific notation has 1 number to the left of the decimal and is multiplied by 10 raised to the number of spaces the decimal is moved.
A) 5.9 x 10 ^ 9
B) 4 x 10 ^ -2
C) 1 km = 100,000 cm
4x 10^-2 x 100,000 = 4000 fireflies per km = 4 x 10 ^3 fireflies per km
5.9x 10^9 x 4x 10 ^3 = 2.4 X 10^13
If you would like to know the value of the larger number, you can calculate this using the following steps:
2 ... 3
18 ... x = ?
2 * x = 3 * 18 /2
x = 3 * 18 / 2
x = 27
The correct result would be 27.
If you paid $22.26 after the discount and tax then 30% is 0.30 and 30% OFF is 1-0.30=0.70
Tax is 6% or 0.06 and along with the initial is 1+0.06=1.06 so P is original price in P×0.70×1.06=22.26
P×0.742=22.26
P=$30 was the original price
The values that correctly models the scenario of the rollercoaster graph will be:
- Red (x) = 6 + 4 × cos(πx/6) if 0 ≤ x < 6
- Green (x) = -2.5 × cos(π(x - 6)/4) + 4.5
- Purple (x) = 3.5 - 3.5 × sin(π(x - 12.5)/5)
<h3>How does the
graph model the situation</h3>
From the complete question,
For Red (x) = 6 + 4 × cos(πx/6) if 0 ≤ x < 6
where at x = 0, Red(x) = 10,
at x = 5, Red(x) = 2.5
For Green (x) = -2.5 × cos(π(x - 6)/4) + 4.5 if 6 ≤ x < 10
where at x = 10, Green (x) = 7,
at x = 6, Green (x) = 2.0
For Purple (x) = 3.5 - 3.5 × sin(π(x - 12.5)/5) if 10 ≤ x ≤ 15
where at x = 10, Purple (x) = 7,
at x = 15, Purple (x) = 0
