Answer:
Step-by-step explanation:
mid point = [(a1 + a2)/2 , (b1 + b2)]
(a1,b1) = first point
(a2,b2) = end point
Using all x coordinates
(a1 + a2)/2 = 1
(-1 + a2)/2 = 1
-1 + a2 = 2
a2 = 3
Using all y coordinates
(b1 + b2)/2 = -1
(-3 + b2)/2 = -1
-3 + b2 = -2
b2 = -1
thus end coordinate = (3, -1)
You will need to add 3 to each side.
x^2-3=15
+3 +3
x^2=12
and go from there
Answer:
Step-by-step explanation:
Hello!
The slope intercept form equation is shown below.
y=mx+b
In this equation, m represents the slope and b is the y-intercept.
We can just plug in our numbers to find our answer.
y=3x-2
I hope this helps!
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
