What is the spring force?The spring force is directly proportional to the deflection of the spring. Let 'x' be the deflection of the spring due to force 'F'. Then the spring force is given as,
F ∝ -x
F = - kx
mg = - kx
The distance D that a spring is stretched by a hanging object varies directly as the weight W of the object. if a 9-kg object stretches a spring 54cm. Then the spring force is calculated as,
9g= - k (54)
- g / 6 = k
Then the equation is given as,
F = (g / 6) x
The distance when the weight is 2 kg will be given as,
2g = (g / 6) x
12 = x
The distance when the weight is 2 kg will be 12 cm. Then the correct option is B.

What are the trigonometric ratios?In mathematics, trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Now, cos(tan^-1(0))
⇒tan^-1(0)=0
⇒cos(0)=1
The value of cos(tan^-1(0)) is 1. Therefore, option C is the correct answer.

plz help me find x!!!!!!!!!!!!!!!!
Answer:
A: 45
B: 110
C: 25
Step-by-step explanation:
all angles of a triangle always add together to make 180
x + 25 + x + 65 = 180
combine like terms
2x + 90 = 180
subtract 90 from both sides of the equation
2x = 180 - 90
divide both sides of the equation by 2
x = 90/2
x = 45

Step-by-step explanation:
Daniel has to carry 32 boxes to his room. He can
carry 4 boxes on each trip. How many trips will
Daniel take? Show your work?
Daniel will take 8 trips.
What is division?The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.
Now it is given that,
Number of boxes = 32
Number of boxes can be carried in each trip = 4
So, Number of trips = Number of boxes / Number of boxes can be carried in each trip
⇒ Number of trips = 32/4
⇒ Number of trips = 8
this is the required number of trips Daniel will take.
Thus, Daniel will take 8 trips.

Identify the range of the graphed function.
Answer:
0<y<8
Step-by-step explanation:
So, as you can see by the graph, the y axis has a plot as low as 0. soo it would be 0. Then the highest plot is marked as high as 8. Therefore its 0<y<8.
Had a hard time wording it so i hope you understand.
The range of the function will be; Range = {y | 0<y<8 }. Then the correct option is A.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
We know that domain means all the possible values of x and the range means all the possible values of y.
So, as we can see by the graph, the y axis has a plot as low as 0. it would be 0. Then the highest plot is marked as high as 8.
The domain of the function is (0, 8] and the range of the function will be
Range = {y | 0<y<8 }
Then the correct option is A.

Step-by-step explanation:
can someone please help? i need to find the slope of a line. it’s for a test!
Answer:
Step-by-step explanation: To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Answer:
The slope is 2/3
Step-by-step explanation:
The equation that the graph gives us is y = 2/3x + 3.
With this equation, we know that the slope is 2/3.
Bonus:
With this equation, we also know that the y-intercept is 3.

How do you do these questions?
Step-by-step explanation:
(a) Fₙ₋₁ > 0, so Fₙ₊₁ > Fₙ. Each term is bigger than the one before it, so the function is increasing, meaning the series will diverge to infinity.
(b) Fₙ₊₁ / Fₙ = (Fₙ + Fₙ₋₁) / Fₙ
Divide.
Fₙ₊₁ / Fₙ = 1 + (Fₙ₋₁ / Fₙ)
Rewrite the second fraction using negative exponent.
Fₙ₊₁ / Fₙ = 1 + (Fₙ / Fₙ₋₁)⁻¹
Take the limit of both sides as n approaches infinity.
lim(n→∞) Fₙ₊₁ / Fₙ = 1 + lim(n→∞) (Fₙ / Fₙ₋₁)⁻¹
Substitute with φ.
φ = 1 + φ⁻¹
Solve.
φ² = φ + 1
φ² − φ − 1 = 0
φ = [ -(-1) ± √((-1)² − 4(1)(-1)) ] / 2(1)
φ = (1 ± √5) / 2
Since the ratio can't be negative:
φ = (1 + √5) / 2
