Step by step explanation
Answer:
80 feet
Step-by-step explanation:
length of pool = 22 , width of pool = 18
feet required for fencing the pool = 2 (l +b)
= 2 ( 22+18)
=2*40
=80feet
Answer:
a.) -9
b.) -1
Step-by-step explanation:
Answer:
T= 2.35 seconds
Step-by-step explanation:
⇒The question is on the time of flight.
⇒Time of flight is the time taken for a projected object to reach the ground.It depends on the <u>projectile angle</u> and the <u>initial velocity</u> of the projectile
Given;
Initial velocity of ball= 110ft./sec.
The projectile angle= 20°
Acceleration due to gravity, g=32 ft./s²
⇒Formulae for time of fright T= (2×u×sin Ф)/g
Where T=time of fright, u=initial velocity of projectile, Ф=projectile angle and g=acceleration due o gravity.
<u>Substituting values</u>
T= (2×u×sin Ф)/g
T=( 2×110×sin 20°) / 32
T= 2.35 seconds
Answer:
x=30
Step-by-step explanation:
because 3 times 30 equal 90 minus 5 is 85
