Answer:
Taking LHS
=1 by cos theta- cos theta
= (1- cos²0)/ cos0
= sin²0/ cos0 ( because 1-cos²0 is also equals to sin²0)
=RHS hence proved
Answer:
y=-5x-6
Step-by-step explanation:
Answer:
43
Step-by-step explanation:
All the even numbers have a factor of 2, so we can eliminate 56 and 34. 75 ends in a 5, so that cannot be a prime number (ending in 5 is a multiple of 5). The sum of the digits of 63 (6+3) is 9, and that is divisible by 3, so that number is also not prime. 43 is a prime number.

Check the pictures below.
if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.
if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is
h(s) = -4.9(s - 2)(s + 1).
