Slope intercept form :
y= -4/3x -2
Answer:
t = 2.5 s
Step-by-step explanation:
h(t)=-16t^2 +80t+96
height will be greatest when the derivative (velocity) is zero
h'(t) = v(t) = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32 = 2.5 s
notice that 0 = -32t + 80 is just a version of the kinematic equation
v = u + at
where v is final velocity at the top of the arc or zero
u is the initial upward velocity or 80 ft/s
a is gravity or -32 ft/s²
t is time in seconds

Answer:63
Step-by-step explanation:
Length of arc =14π
Φ=80°
Radius =r
Length of arc =Φ/360 x 2 x π x r
14π=80/360 x 2 x π x r
14π=(80x2xπxr)/360
14π=160πr/360
Cross multiply
14π x 360=160πr
5040π=160πr
Divide both sides by 160π
5040π/160π=160πr/160π
31.5=r
Diameter =2 x r
Diameter =2 x 31.5
Diameter =63
