I attached the work/steps for my answer.
Answer:
48miles
Step-by-step explanation:
The illustration of the scenario is represented in the attached photo
A triangle WEP is formed.
x = distance of the cell phone from the eastern cell tower
The angles in the triangle
= 70 degrees + 70 degrees + 40 degrees = 180degrees
It is not a right angle triangle. This means that we cannot use Pythagoras theorem. We would apply the sine rule which is as follows:
a/sinA = b/sinB = c/since
a, b and c are the sides of the triangle and A,B and C are the corresponding opposite angles to the sides.
Applying it in our triangle,
x/sin 70 = 48/sin70
x = 48sin70/sin70
x = 480 miles
The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.
The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).
Answer:
The answer to your question is letter B or C they have the same response.
Step-by-step explanation:
From the graph we get the center and the radius
- The center is the point shown in the graph and its coordinates are (1, -4).
- The length of the radius is 3 units, from the center we count horizontally the number of squares (3)
Substitution
(x - 1)² + (y + 4)² = 3²
or (x - 1)² + (y + 4)² = 9
Answer:
5.3×10⁻¹¹ m
Step-by-step explanation:
Applying,
v = 2πr/t................ Equation 1
Where v = speed of the electron in the orbit, r = radius of the orbit, t = time, π = pie
make r the subject of the equation
r = vt/2π................ Equation 2
From the question,
Given: v = 2.2×10⁶ m/s, t = 1.5×10⁻¹⁶ s
Constant: π = 3.14
Susbtitute these values into equation 2
r = (2.2×10⁶×1.5×10⁻¹⁶)/(3.14×2)
r = (3.3×10⁻¹⁰)/6.28
r = 5.3×10⁻¹¹ m
Hence the radius of the orbit is 5.3×10⁻¹¹ m
