Step-by-step explanation:
Answer:slope=10.000/2.000=5.000
x-intercept=2/5=minus 0.40000
y-intercept=2/1=2.00000

(18)
Since BD is an angle bisector , then
∠ DBC = ∠ ABD = 57°
∠ ABC = ∠ ABD + ∠ DBC = 57° + 57° = 114°
(19)
Since BD is an angle bisector , then ∠ ABD = ∠DBC
∠ ABC = 110° , so
∠ ABD = ∠ DBC = 110° ÷ 2 = 55°
Answer:
31.9secs
6,183.3m
Step-by-step explanation:
Given the equation that models the height expressed as;
h(t ) = -4.9t²+313t+269
At the the max g=height, the velocity is zero
dh/dt = 0
dh/dt = -9,8t+313
0 = -9.8t + 313
9.8t = 313
t = 313/9.8
t = 31.94secs
Hence it takes the rocket 31.9secs to reach the max height
Get the max height
Recall that h(t ) = -4.9t²+313t+269
h(31.9) = -4.9(31.9)²+313(31.9)+269
h(31.9) = -4,070.44+9,984.7+269
h(31.9) = 6,183.3m
Hence the maximum height reached is 6,183.3m
