The ratio is 420:700 .
W can simplify this by dividing each number by the GCF which is 140
420:720 = 420/149 : 700 / 140 = 3:5 Answer
The fish is 2.25 ft above the water surface.
Step-by-step explanation:
- Step 1: Given expression for height of the fish above the water surface, y = -16x² + 12x where x is time in seconds. Find height after 0.375 seconds
⇒ y = -16(0.375)² + 12 × 0.375
= -2.25 + 4.5
= 2.25 ft
Answer:
Step-by-step explanation:
The current function of time is defined as follows:
where 
is the charge function.
For the given charge function of time 
we have the following current function:
In the problem it is proposed that 
.
Examining the expression of 
we obtained by deriving with the expression proposed by the problem and comparing term by term:
We conclude that 
and 
.
