Answer:
The answer is B
Step-by-step explanation:
You need to find the derivitive of the equation and ,ultiply by B!!!
Answer:
2.5 km left
The midpoint is half of 5, which is 2.5, so he'll still have 2.5 km left to complete
Answer:
work is pictured and shown
Answer:
The standard form of a hyperbola with vertices and foci on the x-axis:

where:
- center: (h, k)
- vertices: (h+a, k) and (h-a,k)
- Foci: (h+c, k) and (h-c, k) where the value of c is c² = a² + b²
- Slopes of asymptotes:

<h3><u>Part 1</u></h3>
The center of the given hyperbola is (0, 0), therefore:

Therefore
are the vertices. From inspection of the graph,
.
<h3><u>Part 2</u></h3>
Choose two points on the asymptote with the positive slope:
(0, 0) and (4, 6)
Use the slope formula to find the slope:

<h3><u>Part 3</u></h3>
Use the <u>slopes of asymptotes</u> formula, compare with the slope found in part 2:

Therefore, 
<h3><u>
Part 4</u></h3>
Substitute the found values of
and
into the equation from part 1:


<span>As restaurant owner
The probability of hiring Jun is 0.7 => p(J)
The probability of hiring Deron is 0.4 => p(D)
The probability of hiring at least one of you is 0.9 => p(J or D)
We have a probability equation:
p(J or D) = p(J) + p(D) - p(J and D) => 0.9 = 0.7 + 0.4 - p(J and D)
p(J and D) = 1.1 - 0.9 = 0.2
So the probability that both Jun and Deron get hired is 0.2.</span>
