Suppose you observe a star orbiting the galactic center at a speed of 1300 km/skm/s in a circular orbit with a radius of 18 light-days. Calculate the mass of the object that the star is orbiting.
Answer: 1.1818^37 kg
Step-by-step explanation:
Given that:
Orbit speed = 1300 km/s
Radius (r) = 18 light days
Mass of object the star is orbiting :
Using the relation :
M = rv² / G
Where ; r = Radius in m ; v = velocity in m/s
G = 6.67 * 10^-11 = gravitational constant
18 light days in meters = 4.662 * 10^14 m
v = 1300km/s to m/s
v = (1300 * 1000)m /s = 1300000 m/s = 1.3 * 10^6 m/s
Hence ;
M = (4.662 * 10^14 * (1.3 * 10^6)^2 / (2/3) * 10^-10
M = (4.662 * 10^14) * (1.69 * 10^12) / (2/3) *10^-10
M = (7.87878 * 10^26) / 6.67 * 10^-11
= 1.1818^37 kg

Answer:
A. the slope is -2
the y-intercept is (0,1)
Step-by-step explanation:
If y=mx+b, m is the slope and b is the y-intercept.
If we replace the variables with y=-2x+1, we can see -2 is the slope and the y-intercept is (0,1).

Answer:
c = 17.8, A = 25.7°, B = 64.3°
Step-by-step explanation:
Side c can be found from the Pythagorean theorem:
c = √(a² +b²)
c = √(7.7² +16²) = √315.29
c ≈ 17.8 . . . feet
__
The tangent relation is ...
Tan = Opposite/Adjacent
tan(A) = a/b = 7.7/16
A = arctan(7.7/16)
A ≈ 25.7°
B = 90° -25.7°
B = 64.3°
Which point represents 3.9?
Answer:
What do you mean there is not a graph...do you have a picture?
Step-by-step explanation:
Answer: B
Step-by-step explanation:
A = 3.8
B = 3.9
C = 4.0
D = 4.2
You take 4.5 - 3,6 = 0.9, so each big line should be .3.
Mr. Roberts had $9,512 in savings. He saved another $488. He then used all his money to buy 500 books. He sold the books for $35 each. How much did Mr. Roberts earn from selling each book? a. Mr. Roberts earned $ from selling each book. b. Travis got $20 as the answer or the amount Mr. Roberts earned from selling each book. Is his answer correct? yes no c. Tell why Travis is or is not correct.
Answer:
a. Profit from each book = $15
b. No, Travis was wrong.
c. Travis isn't correct because Mr. Roberts made $15 from the sales of each book.
Step-by-step explanation:
Given the following data;
Number of books bought = 500
Selling price = $35
Robert savings (cost price) = $9,512 + $488
Robert savings (cost price) = $10,000
Purchasing price = $10,000/500 = $20
Revenues from book sold = 500 * 35 = $17,500
Total profit = Revenues - Cost price
Total profit = $17,500 - $10,000
Total profit = $7,500
To find the amount earned from each book;
[tex] Profit \; from \; each \; book = \frac {Total \;profit}{Numbers \; of \; book} [/tex]
Substituting into the equation, we have;
[tex] Profit \; from \; each \; book = \frac {7500}{500} [/tex]
Profit from each book = $15
Therefore, Mr. Roberts earned $15 from selling each book.
Check:
Selling price = purchasing price + profit = $20 + $15 = $35

Roberto is 3 years older than Carolyn. In 7 years the sum of their ages will be 81. How old is Roberto now?
Answer: 35
the age of Roberto is x (x > 3)(x ∈ N)
because Roberto is 3 years older than Carolyn => the age of Carolyn is x - 3
in 7 years, the age of Roberto is x + 7; the age of Carolyn is x - 3 + 7 = x + 4
because In 7 years the sum of their ages will be 81 =>
x + 7 + x + 4 = 81
⇔ 2x + 11 = 81
⇔ 2x = 70
⇔ x = 70/2 = 35
=> the age of Roberto is 35

Answer:
2876 books
Step-by-step explanation:
If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...
y1 = 12841 +24.25x
y2 = 48072 +12x
These costs will be equal when ...
y1 = y2
12841 +24.25x = 48072 +12x
12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x
x = 2876 . . . . . . . . . . divide by 12.25
The costs will be the same for production of 2876 books.

Ross wants to know what interest rate he needs to make his $800 grow to
$1000 in 4 years.
Answer:
Why?:
The interest formula is A = P(1+r/m)^mt
A is the Amount, P is principal (initial investment), R is rate, M is times per year (not used) and T is time.
So if we want 1000 = 800(1+r)^4, we need to find R. In this case, R is about 5 percent. (I'm not super confident, so see if you have other answers)

Find the equation of the linear function represented by the table below in slope intercept form.
Answer:
Y=1x-7
Step-by-step explanation:
First use two points to find the slope. I used the first 2. The formula is (y1-y2)/(x1-x2). So (6-8)/(1-3)= -2/-2 = 1. Then you plug in a point and the slope for the equation y1-y2=m(x1-x2). I am using the first point and m is the slope which is 1. Y-6 = 1(x-1)
y-6 = 1x -1 then get y by itself
y=1x-7
