Answer:

False

Step-by-step explanation:

We are given the relation \frac{BX}{XC}=\frac{AB}{AC}.

We take the reciprocal of the given relation,

i.e. \frac{BX}{XC}=\frac{AB}{AC}

i.e. \frac{XC}{BX}=\frac{AC}{AB}.

So, we have that \frac{BX}{XC} ≠ i.e. \frac{AC}{AB}.

Hence, the conclusion is wrong.

David, a platform diver, dives into the pool during practice. The height of David above the water at any given time, s, can be m
ella [17]

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).

Alexxx [7]
3 hours and 55 minutes - 15 minutes would leave 3 hours and 40 minutes. You figure there’s 20 minutes 3 times in an hour so 3x3 is 9 + the extra 2 20 minute periods from the 40 minutes. So 11 batches of cookies, 48x11= 528. Amy made 528 cookies.
