Correct option:
d. 1.64
<h2>
Explanation:</h2>
An object is launched vertically upward from a 25 foot platform and is modeled by the following function:
So this is the equation of a parabola because the object is a projectile so it follows the Projectile Motion.
The object fall back to the ground when 
so:
Since time can't be negative, we only choose the positive value. therefore:
<em>The object fall back to the ground after 1.64 seconds</em>

Answer:
a)$15.95
b) 8kg
Step-by-step explanation:
a)Approach this question by finding how much does it cost for 1g
So,
$2.1/50=$0.042per gram
then, multiple 380 to get the cost of sweets for 380 g
$0.042/gram*380gram=$15.96(Note: the gram cancel out each other)
Which is $15.95 as the question requested
b)This question stated that 3/4 of the metal has 15 kg
So, in order to find the total mass of metal we invert the 3/4 fraction
e.g 4/3*15=20kg
now we have the total mass we can find the mass for 2/5 of the metal
2/5*20kg=8kg
