Answer:
Step-by-step explanation:
u = ?
a = 3.75m/s^2
t = 2 s
v = 9375m/s
a = v-u/t
3.75 = 9375 - u / 2
3.75 × 2 = 9375 - u
7.5 = 9375 - u
u = 9375 - 7.5
=<em> 9367.5 m/s</em>

Step-by-step explanation:
By sine rule:
Let the number of holes of golf you can play be x before your money runs out. I assume both the costs of playing and the income should be equal.
Let your expenses be 25 + 0.50x
Let your income be
a = 18
n = x
d = -1
Sum of income =(a + L)*n/2; L = a + (n - 1)*d
sum of income = (a + a + (x - 1)*d )*x/2
Sum of income = (2a + (x- 1)*(-1) ) * x/2
Sum of income = (2*18 + (x -1 ) (-1) ) * x / 2
Sum of income = (36 - x + 1) * x / 2
Sum of income = (37 - x )* x / 2 Now the income has to equal the expenses.
25 + 0.5x = (37 - x)*x/2 Multiply both sides by 2 and remove the brackets.
50 + x = 37x - x^2 Bring the right side over to the left.
x^2 - 36x + 50 = 0
You need help from the quadratic formula
a = 1
b = -36
c = 50
This does not come to anything nice. I'm getting x = 34.6 holes or x = 1.44.
