Answer:
4 + 9x² + 1x³ + 12x⁵
Step-by-step explanation:
3x² + 6x² = (3 + 6)x² = 9x²
4 + 3x² + 8x³ + (-7x³ + 12x⁵ +6x²) = 4 + <u>3x² + 6x² </u> + <u>8x³ - 7x³ </u> + 12x⁵
= 4 + 9x² + 1x³ + 12x⁵

Answer:
2.1 * 10 ^3
Step-by-step explanation:
5.67 * 10 ^7 ÷2.7 x 10^4
Divide the numbers
5.67 / 2.7 =2.1
Divide the exponents
10^7 / 10 ^4
Remember when dividing power, we subtract the exponents
10 ^(7-4) = 10^3
Put this back together
2.1 * 10 ^3
Verify that this is in scientific notation
Since this is in scientific notation, we are done

Answer:
29 seconds
Explanation
anchor dropped in to water at the rate = 2.5 m/s
so for one second = 2.5 m
so for 45 sec= 2.5 x 45 = 112.5 m
but it was already 40 m under water, so it have fallen from= 112.5-40= 72.5 m
so as we know the rate of falling was =2.5 m/s
so for 72.5 meter, it took = 72.5 /2.5= 29 sec
it took for anchor to get down to the water surface after it started dropping.
