Answer:
1) 1.1 seconds
2) 13.5 feet
<h3>Part A</h3>
<u>Apply quadratic formula</u>:
<u>Simplify following</u>
In decimal form:
Conclusion:
As time is be only positive: t = 1.1 seconds
<h3>Part B</h3>
<u>insert t = 0.5</u>
<u>simplify</u>
1. It is already in slope intercept form so y=2/5x-12/5
2. Y=2/3x-2
Isolate the y
-9y=-6x+18
y=2/3x-2
3. y=4/5x+14
Isolate the y
-5y=-4x-70
y=4/5x+14
89.890 Is what I would think it would be. Hope it helped.
Answer:
False.
Step-by-step explanation:
1. 0.2 is 1 percent of 20.
2. 0.2x20 is 4
3. 14 divided by 0.2 is 70, that means 14 is 70% of 20.
4. Therefore, 4 is 20% of twenty.
Answer:
length= 24 inches
width= 7 inches
Step-by-step explanation:
Start by writing down what you know.
width= w
length= 3w+3
Then, we can substitute into the perimeter of a rectangle equation, P=2l+2w.
62= 2(3w+3) + 2(w)
62=6w+6+2w
62=8w+6
56=8w
7=w
Now, plug this into our original equations for length and width:
width=7
length= 3(7)+3, so 24
