Step-by-step explanation:
b) average velocity : ∆x/∆t = 100/9.8 ≈ 10.204 m/s
c) ∆x = v.∆t = 10.204 × 3 = 30.612 m
d) ∆t = ∆x/v = 80/10.204 = 7.84 s
Answer:
13cm
Step-by-step explanation:
Umm, well is it asking like 5 * 81
Replace the x's values in the equation with 5.
f(5)= -16(x-4) + 225
= -16(1) + 225
= -16 + 225
= 209
The Answer is 209
Answer:
a) #4 vertical angles are congruent
b) # 1 ∠3 ≅ ∠7
c) # 6 Transitive property
Step-by-step explanation:
a. Vertical angles - opposite angles that are equal.
b. corresponding angles - in the same place but on different parallel lines
and are equal.
c. a = b, b = c so a = c
