Answer:
B
Step-by-step explanation:
When adding or subtracting fractions, multiply to get the same denominator (bottom number).
When multipling two fractions, just multiply straight across, factor diagonally if possible.
When dividing fractions, flip the second fraction over and multiply.
For the polynomials, you just need to combine like terms.
3x + 4y² + 7x + 6y² = (3x + 7x) + (4y² + 6y²) = 10x + 10y²
You can factor this further but I don't know if its necessary.
= 10(x + y)
Let me know if you have any questions.
When you take a normal square root, that's also the same is raising to the 1/2 power. So you need the 5th root of 15, or 15^(1/5) = 1.71877...
BUT, multiplication comes first, order of operations
so 2.24 * 2 = 4.48
Add 15^(1/5) to 4.48 and keep as many decimals as you need
Answer:
7 feet 10 inches
Step-by-step explanation:
A ball is falling from a height of 30 feet and then it bounces. After each bounce, the maximum height of the ball is 80% of the previous height.
So, after 1st bounce, the maximum height was (0.8 × 30) feet.
Similarly, after 2nd bounce, the maximum height was 0.8(0.8 × 30) feet.
In this way, the maximum height of the ball after nth bounce will be
So, after 6th bounce the maximum height will be feet = 7 feet 10 inches (Appx.)
