Answer:
t=6
Step-by-step explanation:
ground height = 0
(are you sure your formula is correct? isn't it - 16t²?)
if h=16t² +64t+192 is true then
16t² +64t+192 = 0
t² + 4t + 12 = 0
t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2
There is no solution of t
if it is h= - 16t² +64t+192
0 =- 16t² + 64t + 192
t² - 4t - 12 = 0
(t + 2) (t -6) = 0
t should be positive
t = 6 sec
Answer:
x= 0, -1
Step-by-step explanation:
320 because you added the two numbers to get the total.
we know that
total of sum of arc is 360
so, sum of both arc must be 360
so, we get
now, we can solve for x

Answer:
2.34 * 10^5.
Step-by-step explanation:
234000 = 2.34 * 10^5
- there are 5 digits after the first number so the exponent is 5.
