Answer:
3
Step-by-step explanation:

It will hit the floor when h=0
-16t^2+14.8t+3.9=0
using the quadratic formula...
t=(-14.8±√468.64)/-32, since t>0
t ≈ 1.139 seconds
Answer:
68
Step-by-step explanation:
Find the scale Factor:
What do you do to 10 to make it 4?
Divide by 2.5 or Multiply by 0.4
Since, Scale factors are always written as multiplications, use x 0.4
Find the area of the smaller pentagon:
Value 1 x Scale Factor = Area of larger pentagon x 0.4 = 68.8 ≈ 68

Answer:
The measure of angle MNL is 
Step-by-step explanation:
see the attached figure to better understand the problem
In this problem we know that
angle GNH is congruent to angle KNL
-----> by vertical angles

so

Find the measure of angle MNL
------> by complementary angles
Substitute and solve for m<MNL
