I think the answer to your problem is exponents.
Answer:
Awnser is C
Vertex (1, -2), Axis of symmetry is x = 1
<h3>
Answer: Approximately 119.76 meters</h3>
===================================================
Work Shown:
x = starting length of the shadow
y = height of the pole
tan(angle) = opposite/adjacent
tan(58) = y/x
1.6003345 = y/x
1.6003345x = y
x = y/1.6003345
x = (1/1.6003345)y
x = 0.62486936y
-------------------------
When the angle changes, the adjacent side gets 90 meters longer
tan(angle) = opposite/adjacent
tan(36) = y/(x+90)
0.72654253 = y/(0.62486936y+90)
0.72654253(0.62486936y+90) = y
0.453994166y + 65.3888277 = y
65.3888277 = y-0.453994166y
65.3888277 = 0.546005834y
0.546005834y = 65.3888277
y = 65.3888277/0.546005834
y = 119.758478075162
y = 119.76
The height of the pole is about 119.76 meters.
A, A and B. Because the first one says that ''t is less than or equal to 50 '' so it can not be at least 50 ( B ).
The second one says ''x is greater than 4'' so x can not be at most 4 because the inequality is strict, there is no ''or equal to'' .
Hope this helped
To find the cost per pound you simply divide the amount paid by the amount purchased
For Beef it would be:
$7.20 ÷ 2.0 = $3.60
For Pork it would be:
$8.10 ÷ 2.5 = $3.40
For Chicken it would be:
$9.80 ÷ 3.5 = $2.8
