Answer:
Approximately [tex]30\; \rm N[/tex] toward the center of the object.
Step-by-step explanation:
Look up the gravitational constant and the mass of the earth:
[tex]\begin{aligned}G &\approx 6.67 \times 10^{-11}\; \rm m^{3} \cdot kg^{-1} \cdot s^{-2} \\ &= 6.67 \times 10^{-11} \; \rm N \cdot m^{2} \cdot kg^{-2}\end{aligned}[/tex].
[tex]M \approx 5.97 \times 10^{24}\; \rm kg[/tex].
Convert the unit of distance to standard units:
[tex]\begin{aligned}r &= 25600\; \rm km \\ &= (25600 \times 10^{3})\; \rm m \\ &= 2.56 \times 10^{7}\; \rm m\end{aligned}[/tex].
Consider two spherical objects with mass [tex]m_{1}[/tex] and [tex]m_{2}[/tex]. Let [tex]r[/tex] denote the distance between the centers of the two objects. By Newton's Law of Universal Gravitation, the size of the gravitational force between these two objects would be:
[tex]\begin{aligned}F &= \frac{G \cdot m_{1} \cdot m_{2}}{r^{2}}\end{aligned}[/tex].
Thus, the size of the gravitational force between this object and the earth would be:
[tex]\begin{aligned}F &= \frac{G \cdot m \cdot M}{r^{2}} \\ &\approx \frac{1}{2.56\times 10^{7}\; \rm m} \\ &\quad \times 6.67 \times 10^{-11}\; \rm N \cdot m^{2}\cdot kg^{-2} \\ &\quad \times 50\; \rm kg \times 5.97 \times 10^{24}\; \rm kg \\ &\approx 30\; \rm N\end{aligned}[/tex].
Since gravitational force is attractive, the [tex]50\; \rm kg[/tex] object in this question would attract the earth through the gravitational force. Thus, this force would point towards the center of this [tex]50\; \rm kg\![/tex] object.
Circle A has a circumference of 2 2/3m. Circle B has a diameter that is 1 1/2 times as long as Circle As diameter. What is the circumference of Circle B?
Step-by-step explanation:
the circumference of a circle is
c = 2×pi×r
with r being the radius.
the diameter of a circle is always twice its radius.
circle A
2 2/3 = 8/3 = 2×pi×r
4/3 = pi×r
r = 4/3 / pi = 4/(3×pi) = 0.424413182... m
the diameter is then : 0.848826363... m
the diameter of B is 1.5 times the diameter of A :
1.273239545... m
therefore, the radius of B is 0.636619772... m
and so, the circumference of B is
2×pi×0.636619772... = 4 m
of course, if we had considered that both diameter and circumference are in linear dependence (see the formula for the circumference), we could get the result much faster. if the diameter increases 1.5 times, then also the circumference increases 1.5 times :
2 2/3 = 8/3 × 1.5 = 8/3 × 3/2 = (8×3)/(3×2) = 8/2 = 4 m

what is the equation of the line?
Answer:
y = 3x + 19
Step-by-step explanation:
Point slope formula: y-y1=m(x-x1)
y - 4 = 3(x - (-5))
y - 4 = 3(x + 5)
y - 4 = 3x + 15
y = 3x + 19

Y= 3(x+4) to the power of 2 - 8 I need to know the table of values
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The equation is in vertex form, so you can tell that the vertex of the graph is (x, y) = (-4, -8). This suggests your table should have values that are symmetrical about x = -4. The attachment shows one possible table of values.
__
It is generally convenient to let a graphing calculator or spreadsheet compute a table of values for you.
Put each chosen value of x into the equation and do the arithmetic.
For x=-5, ...
y = 3(-5+4)² -8 = 3(-1)² -8 = 3 -8 = -5
Then (-5, -5) will be a point in your table. Recognizing the symmetry of the function, you know that (-3, -5) will also be a point in your table.

How many triples of three positive integers have a product of 16?
There are 15 possible triples of three positive integers whose product is 16.
According to this question, we must find the quantity of all possible triples such that they have a product of 16. By factor decomposition, we have that 16 is equal to the following product of prime numbers:
[tex]16 = 2^{4}[/tex]
There are the following triples considering order of factors:

The measure of one angle is 7 times the measure of its COMPLIMENT. Find the measure of each angle.
Step-by-step explanation:
given,
the complete angle is complementry angle which is 90°
let the first angle be x and second angle be 7x ( as second angle is 7 times more than first angle )
now,
→ x + 7x = 90
→ 8x = 90
→ x = 90/8 = 11.25
therefore
1st angle = x = 11.25°
2nd angle = 7x = 7 × 11.25 = 78.75°
hope this answer helps you dear take care and may u have a great day ahead!

the slope between two points can be defined as the change in y over the change in x. Consider (0, 11) as your first point and (1,4) as your second point.
To find the slope, do:
(y2 - y1) / (x2 - x1) = slope
(4 - 11) / (1 - 0) = slope

Each pair of the first 18 terms sum to 1/20:
19/20 - 18/20 = 1/2017/20 - 16/20 = 1/20...3/20 - 2/10 = 1/20These 18 terms sum to:

Answer:
Since angle 1 = angle 3 (vert opp angles),
angle 1 = angle 3 = 180°-129° (adj angles on a str line)
= 51°
angle 4 = angle 2 = 129° (vert opp angles)
Hence,
angle 1 = 51°
angle 3 = 51°
angle 4 = 129°

Step-by-step explanation:
6x-3= Ax-3-2x
6x-3= (A-2)x -3
6= A-2
A= 6+2
A=8
Given :-
A equation 6x - 3 = Ax - 3 - 2xTo Find :-
The value of A so that the equation has infinitely many solutions .Solution :-
Given equation ,
6x - 3 = Ax - 3 - 2x .Add 3 to both sides ,
6x = Ax - 2xAdd 2x to both sides ,
6x + 2x = AxSimplify ,
8x = AxDivide both sides by A .
A = 8Hence the value of A should be 8 .
