Answer:
Just say what you did in your math equation
Answer:
1197 miles.
<h3>Step by step explanation:</h3>
Speed(s) = 63 mph
Time(t) = 19 hours
Distance(d) = ?
We know,
D = S × T
= 63 × 19
= 1197 miles
Answer:
See attached
Step-by-step explanation:
<em>All answers in one graph, refer to attached</em>
<u>The function we need is</u>
- C(x) = 100(2*5280 - x) + 180
, where 2*5280= 2 miles
Table included as well
The vertex is about x = 19 ft which corresponds the minimum cost
Any other value, including negative reveal greater cost
- <u><em>Note. there is a bit confusion over 2 miles or 2000 ft, but the graph is going to be same in shape and vertex for x, the value for cost will be different</em></u>
- <em>-sin </em><em>X</em>
- <em>4</em><em>x</em><em> </em><em>cos </em><em>x</em><em> </em><em>-</em><em>4</em><em> </em><em>sin </em><em>x</em>
<h2><em>hope </em><em>it</em><em> helps</em><em>!</em></h2>
You follow the rules for the quadratic formula, where
x= (-b +- √(b²-4ac) )/2a
Filling a, b and c in yields
x = (8 +- √(64-164) ) / 2 =>
x = (8 - √-100)/2 or x = (4 + √-100)/2
Well, √-100 = 10i, so then you simplify to the last answer, D:
x = 4-5i or x=4+5i
