Hey there! :)

Answer:

First choice. 36/100 or 36%.

Step-by-step explanation:

Total # of squares:

10 × 10 = 100 squares.

# of squares shaded:

6 × 6 = 36 squares.

shaded/total to find the percent shaded:

Fraction: 36/100

Percentage: 36/100 × 100 = 36%.

Taya2010 [7]

Answer:

$v_f=9.0774m/s$

Step-by-step explanation:

Let's assume

initial velocity =vi

final velocity=vf

initial height =hi

final height =hf

acceleration due to gravity =g

we can use formula

$\frac{1}{2}v_i^2+gh_i= \frac{1}{2}v_f^2+gh_f$

we are given

$v_i=2m/s$

$h_i=2\times 2=4$

$h_f=0$

$g=9.8m/s^2$

now, we can plug values

$\frac{1}{2}(2)^2+(9.8)(4)= \frac{1}{2}v_f^2+(9.8)(0)$

now, we can solve for vf

$\frac{1}{2}(2)^2+(9.8)(4)= \frac{1}{2}v_f^2$

we get

$v_f=9.0774m/s$
