-5T^2 + 45t
to find the x intercepts equate to 0 and silve for t
-5t^2 + 45t= 0
-5t(t - 9) = 0
t = 0 and 9 These are the x intercepts
the vertex can be found by converting the function to vertex form
(ht) = -5(t^2 - 9t)
= -5[ (t - 4.5t)^2 - 20.25]
so the coordinates of the vertex are t = 4.5 and h(t) = -5 * -20.25 = 101.25
( 4.5 , 101.25)
The maximum height is 101.25 m and time it takes to reach this height is 4.5 seconds.
The area of a parallelogram can be found using the formula
.
We know that
and
, so we can divide 12 by 5¼ to get b.
Let's put 5¼ as an improper fraction to make dividing easier.
5 wholes = 20 fourths. 20 + 1 = <u>21 fourths</u>.
Dividing by a fraction is the same thing as multiplying by its reciprocal.
To find the reciprocal we flip the numerator and the denominator and get 4/21.
4/21 × 12 = 48/21 which as a simplified mixed number is
