Answer:
Right 2, up 3
Step-by-step explanation:
In the vertex form transformations....
f(x) = a(x-h)²+k
- a - indicates <em>vertical stretches</em>, <em>compression</em>, and/or a <em>reflection across the x-axis</em>.
- h - indicates only on the <u><em>x-axis</em></u>. Negative = Goes right, Positive - goes left
- k - indicates only on the y-axis. Positive = up, negative = down
P = 2(L + W)
P = 258
L = 2W - 9
258 = 2(2W - 9 + W)
258 = 2(3W - 9)
258 = 6W - 18
258 + 18 = 6W
276 = 6W
276/6 = W
46 = W <=== here is the width
L = 2W - 9
L = 2(46) - 9
L = 92 - 9
L = 83 <== here is the length
Answer:
62.6%
Step-by-step explanation:
To convert the mountain height to miles, we divide its height in feet by the number of feet per mile. We want the fraction of that represented by 3 miles, so ...
(3 mi)/((25,289 ft)/(5,280 ft/mi)) × 100%
= 3(5280)/25289 × 100% ≈ 62.6%
If you climbed 62.6% of the mountain's height, you would be 3 miles above sea level.
