Answer:
F = k/d^2
Step-by-step explanation:
We can see from the question that the force of attraction F is proportional to the inverse of the square of the distance separating the bodies, d.
So we have;
F α 1/d^2
So, introducing a constant of proportionality k,
F = k/d^2
Hence the formula connecting F and d is; F = k/d^2

Answer and Step-by-step explanation:
Trigonometric Function (These only work for right triangles):
SOH-CAH-TOA
S = Sine = sin
C = Cosine = cos
T = Tangent = tan
O = Opposite (side)
H = Hypotenuse (side)
A = Adjacent (side)
SOH = sin(angle) = [tex]\frac{opposite}{hypotenuse}[/tex]
CAH = cos(angle) = [tex]\frac{adjacent}{hypotenuse}[/tex]
TOA = tan(angle) = [tex]\frac{opposite}{adjacent}[/tex]
1. sinQ (Q is the angle) = [tex]\frac{14}{50} = \frac{7}{25} = 0.28[/tex]
Use Pythagorean Theorem to find side PQ. [tex]14^{2} + PQ^{2}= 50^{2} \\PQ^{2} = 2304\\PQ = 48[/tex]
2. cosQ = [tex]\frac{48}{50} = \frac{24}{25} = 0.96[/tex]
3. tanQ = [tex]\frac{14}{48} = \frac{7}{24} = 0.29[/tex]

solving systems of linear inequalities
Answers
Answer:
YES. (2, 7) is a solution of the system.
Step-by-step explanation:
System of linear inequalities has been given as,
y ≥ -x + 1 --------(1)
y < 4x + 2 ------(2)
If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.
By substituting the coordinates of point (2, 7) in inequality (1),
7 ≥ -2 + 1
7 ≥ -1
True.
By substituting the coordinates of point (2, 7) in inequality (2),
7 < 4(2) + 1
7 < 9
True.
Therefore, point (2, 7) lie in the solution area of system of inequalities.
YES. (2, 7) is a solution of the system.

Triangle DEF is dilated to create triangle DAB. What scale factor was used?
please hurry in less than 10 min
Answers
Answer:
Not sure how you would word it but the bigger triangle is 2 times larger than DEF.
Step-by-step explanation:
DE=4
AE=4
4+4=8
AD=8
Hope this helps!!
The scale factor used to create DAB from triangle DEF is 2.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
The length of the base of the triangle DEF is 4 units and of DAB is 8 units.
The length of the height of DEF is 3 units and that of DAB is 6 units.
From this, we conclude that the scale factor is 2 as 8 is a multiple of 2×4 and 6 is a multiple of 2×3.

3x-9=7x+14 solve for x
Answers
Answer:
x= - 23/4
Step-by-step explanation:
Add 9 to both sides of the equation:
3x -9 = 7x +14
3x- 9 + 9 = 7x +14 +9
Simplify:
3x -9 + 9 = 7x +14 +9
3x = 7x +14 +9
3x =7x +14 +9
Subtract 7x from both sides of the equation:
3x= 7x +23
3x -7x = 7x +23 - 7x
Simplify Again:
3x -7x = 7x +23 -7x
-4x =23
Combine like terms:
-4x =23
Divide both sides of the equation by the same terms:
14x/ 14 = 23/ -4
Cancel terms that are both the numerator and the denominator:
x= - 23/- 4
Answer:
x= - 23/4
Raul calculated that he would spend $125 on school supplies this year. He actually spent $87.50 on school supplies. What is Raul’s percent of error?
A 42.9%
B 37.5%
C 30%
D 3%
Answers
Answer:
C 30%
Step-by-step explanation:
87.50/125= 0.70
1-0.7-0.3
Answer:
42.9%
Step-by-step explanation:
So you would use [ ((V2 - V1) / |V1|) * 100 ]
V1 = 87.5 to V2 = 125
= ((125 - 87.5) / |87.5|) * 100
= (37.5 / 87.5) * 100
= 0.428571 * 100
= 42.8571% change
= 42.8571% increase
Then you round to 42.9!
Hope it helps! :)
3. Select all answers that would create a dilation.

O (x,y) -----> (3x,3y)
O (x,y) -----> (1.2x,1.2y)
Answers
Answer:
Option B,D and E will create dilation.
Step-by-step explanation:
Dilation is the enlarging or shrinking of an element using a common scale factor.
If the same factor is multiplied by the elements, the dilation is created.
Looking at the options:
Option A
O (x,y) -----> (2x,4y)
if we take 2 as common we get 2 (x,2y) not the original coordinates (x,y). So, no dilation.
Option B
O (x,y) -----> (-2x,-2y)
if we take -2 as common we get -2(x,y) which is same as original coordinates. It would create dilation.
Option C
O (x,y) -----> (92x,2y)
if we take 2 as common we get (46x,y) not the original coordinates (x,y). So, no dilation.
Option D
O (x,y) -----> (3x,3y)
if we take 3 as common we get 3(x,y) which is same as original coordinates. It would create dilation.
Option E
O (x,y) -----> (1.2x,1.2y)
if we take 1.2 as common we get 1.2(x,y) which is same as original coordinates. It would create dilation.
So, Option B,D and E will create dilation.

following system of equations can be used to represent the situation. Determine the best method to solve the system
of equations. Then solve the system.
Answers
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips
