The answer should be 1y and -6y
Answer:
(c).
Step-by-step explanation:
h(t) = - 16 t² + 80 t
Coordinates of the vertex are:
<em>t</em> = -
=
= <em>2.5 sec. </em>
<em>h</em> = - 16(2.5)² + 80(2.5) = - 100 + 200 = <em>100 ft</em>.
Answer:
$16
Step-by-step explanation:
1. Simplify 12/45 which is now 4/15. Now we know $4 is made every 15 minutes.
2. Divide into 60(minutes) by the the 15. So 60÷15=4. Now we the number of times 15 can be divided into 60.
3. Multiply the ratio 4/15 by 4/4 to see how much is made in an hour. 4x4/15×4=16/60.
$16 is made in 60 minutes (1 hour).
Answer:
(a)
(b)62.85cm
Step-by-step explanation:
The growth rate of the shrub is given as:

Where t=time in years, h=height in centimeters
(a)First, we solve for the height h(t) by integrating.

(b)The shrub are sold after 7 years of growth. Therefore, we determine the value of h(t) when t=7 years.

The Shrubs are 62.85cm tall when they are sold.
