Your answer is 98
This is because. u (18) + xy (10 × 8 = 80) so
18 + 80 = 98
Hope this helped
Answer:
The launch angle should be adjusted to 30.63°
Step-by-step explanation:
The range of a projectile which is the horizontal distance covered by the projectile can be expressed as;
R =(v^2 sin2θ)/g
Where
R = range
v = initial speed
θ = launch angle
g = acceleration due to gravity
For the case above. When the projectile is launched at angle 13° above the horizontal.
θ1 = 13
R1 = (v^2 sin2θ1)/g
R1 = (v^2 sin26°)/g ....1
For the range to double
R2 = (v^2 sin2θ)/g .....2
R2 = 2R1
Substituting R2 and R1
(v^2 sin2θ)/g = 2 × (v^2 sin26°)/g
Divide both sides by v^2/g
sin2θ = 2sin26
2θ = sininverse(2sin26)
θ = sininverse(2sin26)/2
θ = 30.63°
Answer:
The probility is hight .
Step-by-step explanation:
because there are more pennies then quarters so there's about a 85 to 75% chance
Answer:
y = 4/3x +4
Step-by-step explanation:
The first step is to find the slope
We have two points (-3,0) and (0,4)
m = (y2-y1)/(x2-x1)
= (4-0)/(0--3)
= 4/(0+3)
=4/3
Then we need the y intercept (where it crosses the y axis)
It crosses at 4
The form of the equation is
y= mx+b, where m is the slope and b is the y intercept
y = 4/3x +4
