Answer:
4 ft downwards
Step-by-step explanation:
old height off the ground :
7^2+b^2=25^2
49+b^2=625
b^2=576
b=24
new height off the ground :
7+8=15
15^2+ b^2 =25^2
225+b^2 = 625
b^2 = 400
b=20
difference between heights :
24 - 20 = 4
Answer:
V = 6 or V = -6
Step-by-step explanation:
Solve for V over the real numbers:
V^2 = 12^2 - 6 2 9
12^2 + 2 (-6) 9 = 36:
V^2 = 36
Take the square root of both sides:
Answer: V = 6 or V = -6
Answer:
CD =3m
Step-by-step explanation:
AB=BD
BC=2CD --> CD=1/3 BD
--> AD= 6CD
Answer:

Step-by-step explanation:
