<span>place vertex at (0,0)
basic equation: x^2=4py
p=distance from vertex to focus)
y=at ends of parabolic cross section
y = x^2/4p
Given y= 1/48x^2
So,
1/48x^2=X*2/4p
1/4p = 1/48
4p = 48
p = 48/4 = 12 ft</span>
Her average speed = total distance / time taken = 120 / 2 = 60 km/h.
Answer:
$9.3 dollars.
Step-by-step explanation:
To solve this question, you will need to begin by finding the percentage left of the original value:
100%-70%= 30% left.
Now, to find the exact value of the discounted item, you will solve for 30% (0.3) of $31:
0.3×31= $9.3 dollars.
Is the equation y = - 4/5x - 2 or <span>y = - 4/(5x - 2)?
</span>
.60 * 42 = 25.2
So, he/she would have answered 25 questions correctly.
