what is 550÷1000000??
This is a long division problem.
Answer:
[tex]5.5*10^{-4}=\frac{11}{20000}=.00055[/tex]
Step-by-step explanation:
[tex]550/1000000=55/100000[/tex] | Take one 0 from each side of the divider
Now that it's simplified, we can more easily solve the problem:
[tex]55/100000=5.5*10^{-4}[/tex]
We can also write this as a fraction or a decimal:
[tex]5.5*10^{-4}=\frac{11}{20000}=.00055[/tex]
Inverse for f(x)=1/2x+3
Answer: [tex]f^{-1}(x)=2x-6[/tex]
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[tex]y=\frac{1}{2}x+3[/tex] [switch x and y]
[tex]x=\frac{1}{2}y+3[/tex] [subtract both sides by 3]
[tex]x-3=\frac{1}{2} y[/tex] [multiply both sides by 2]
[tex]y=2x-6[/tex]
Now, we know that [tex]f^{-1}(x)=2x-6[/tex].

Answer:
857.4 ohms
Step-by-step explanation:
The new frequency is 50.2/61.4 times the old frequency. Since the reactance varies inversely with frequency, the new reactance will be 61.4/50.2 times the old reactance:
reactance at lower frequency = (701 ohms)×61.4/50.2 ≈ 857.4 ohms

A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 72 km/hcurrent: 16 km/hStep-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.

ОА
A. x = - 1 2 3 4
B. y = - 1/2 x ²
C. x = 1 / 4²
Do y = x
Answer:
the answer is "B"
the "a" (as in ax^2) is negative thus the parabola "goes downward"
Step-by-step explanation:
The equation of parabola is,
y = - 1/2x²
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
We have to given that;
In a parabola,
Vertex = (0, 0)
Since, We know that;
Standard form of equation of parabola is,
y = a (x - h)² + k
Where, (h, k) = (0, 0) = vertex
Hence, We get;
y = a (x - 0)² + 0
y = ax²
Here, A point on parabola is, (2, - 2)
- 2 = a (2)²
a = - 2 / 4
a = - 1/2
Hence, The equation of parabola is,
y = - 1/2x²

What is the radius of the circle? Example how you know..
Answer:
r=7
Step-by-step explanation:
C is at x=1 at circle side is at 8
8-1= 7
so, r=7
Answer:
The radius of the circle is 7 units.
Step-by-step explanation:
Radius is the measure from the center point of a circle to a point on the outside edge. Since you have coordinates, you can find the radius using distance formula.
You could also just count how many units are between the center and the edge to get 7 units because 8 - 1 = 7
What is the value of p?
A.60°
B. 40°
C. 90°
D. 50°
Answer:
D . p = 50
Step-by-step explanation:
To find the value of p we first need to find the values of inner angles
180 - 140 (linear pair)
= 40
180 -90 (linear pair)
= 90
now use angle sum property of triangle
40 + 90 + p = 180
130 + p = 180
p = 180 - 130
p = 50

A restaurant owner collected data about the types of items customers ordered. The table shows the probability that a customer will order each type of item when they visit the restaurant. Move words to the table to describe the likelihood of a customer ordering each item. Soft Drink Dally Special Dessert Appetizer 0.80 0.25 0.48 0.06 Probability that a customer will order Likelihood that a customer will order Certain Impossible Likely Unlikely Neither-likely nor unlikely
Using probability concepts, it is found that the matchings are:
Soft Drink - Likely.Dally Special - Unlikely.Dessert - Neither likely nor unlikely. Appetizer - very unlikely.------------------------
Probabilities assume decimal values between 0 and 1.The closer the probability is to 1, the more likely the event is to happen.------------------------
0.8 probability of a customers ordering a Soft Drink, which is a close value to 1, so Soft Drink - Likely.0.25 probability of a customer ordering a Dally Special, which is considerably less than 0.5, thus Dally Special - Unlikely.0.48 probability of a customer ordering a Dessert, which is around 0.5, thus Dessert - Neither likely nor unlikely.0.06 probability of a customer ordering an Appetizer, which is quite close to 0, so Appetizer - very unlikely.A similar problem is given at https://brainly.com/question/21408404
