Answer: 2.99

Explanation: In this problem, we're asked to round 2.9857 to the nearest hundredth. The hundredths place is located two places to the right of the decimal point so the digit in the rounding place is the 8.

Next, look at the digit to the right of the rounding place.

Since the digit to the right of the rounding place, 5, is greater than or equal to 5, we round up.

This means that we add 1 to the digit in the rounding place so 8 becomes 9 and we change all digits to the right

of the rounding place to 0.

So 2.9857 rounded to the nearest hundredth is 2.9900.

Finally, remember that when rounding decimals, we can drop and zeroes to the right of the decimal point that are also to the right of the rounding place.

So our final answer 2.99.

Find the coordinates of P so that P partitions AB in the ratio 3:4 with A(-9,-9) and B(5,-2).

ivolga24 [154]

The coordinates of point P are (-3 , -6)

Step-by-step explanation:

If point (x , y) partitions line AB where A = $(x_{1},y_{1})$ and B = $(x_{2},y_{2})$

at a ratio $m_{1}:m_{2}$ from A then:

1. $x=\frac{x_{1}m_{2}+x_{2}m_{1}}{m_{1}+m_{2}}$

2. $y=\frac{y_{1}m_{2}+y_{2}m_{1}}{m_{1}+m_{2}}$

∵ P partitions AB in the ratio 3 : 4

∴ $m_{1}:m_{2}$ = 3 : 4

∵ A = (-9 , -9) and B = (5 , -2)

- Substitute the coordinates of points A and B in the rules above

∵ $x=\frac{(-9)(4)+(5)(3)}{3+4}$

∴ $x=\frac{-36+15}{7}$

∴ $x=\frac{-21}{7}$

∴ x = -3

The x-coordinate of P is -3

∵ $y=\frac{(-9)(4)+(-2)(3)}{3+4}$

∴ $y=\frac{-36+(-6)}{7}$

∴ $y=\frac{-42}{7}$

∴ y = -6

The y-coordinate of P is -6

The coordinates of point P are (-3 , -6)

4,16,8,32,16,<br> What comes after

beks73 [17]

Your answer is 64.
If you look at it the pattern is:
Multiply by 4, then divide by 2
4 times 4= 16
16 divided by 2= 8
8 times 4= 32
32 divided by 2= 16
Now you would multiply by 4
16 times 4= 64
