It would take the air 45 seconds to travel 5,850 meters.
Step-by-step explanation:
if parabola has a vertex not in x-axis, it should have 2 x intercept
x-vertex = -2
first x intercept = 3
second x intercept should -7
so the equation will like this
y = a(x-x1)(x-x2)
y = a (x-3)(x+7)
y = a(x² + 4x - 21)
5 = a((-2)² + 4(-2) - 21)
5 = a(4 - 8 - 21)
5 = a(-25)
a = 5/(-25)
a = -1/5
then the equation is
y = (-1/5)(x² - 4x - 21)
or you can write as
y = -x²/5 + 4x/5 + 21/5
or as this one
5y = -x² + 4x + 21
Answer:
An easy way to do this problem is to follow PEMDAS if you don't know what that is it is P=() E I forgot M=Mutliply D=Division A=addition S=Sabtraction
But to do this problem first do the problem in the (3/2. 1/4) I hope this helps please reward brainlist.
Answer:
Do you have options.
If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.
Step-by-step explanation:
can be transformed into
: both expressions are equivalent, the root of certain number is equivalent to that number power at a fraction whose denominator is the index of the root. The simpliest example for this statement is
(the squared root of x equals x raised at 1/2).
and
. In this case, then
, which is the final expression.
