The tension does not approach infinity.
<span>Let's analyze free body diagrams (FBDs) for each mass, considering the direction of motion of m₁ as positive.

For m₁: m₁*g - T = m₁*a

For m₂: T - m₂*g = m₂*a

Assuming a massless cord and pulley without friction, the accelerations are the same.

From the second equation: a = (T - m₂*g) / m₂

Substitute into the first:
m₁*g - T = m₁ * [(T - m₂*g) / m₂]
Rearranging:
m₁*g - T = (m₁*T)/m₂ - m₁*g
2*m₁*g = T * (1 + m₁/m₂)
2*m₁*m₂*g = T * (m₂ + m₁)
T = (2*m₁*m₂*g) / (m₂ + m₁)
Taking the limit as m₁ approaches infinity:
T = 2*m₂*g

This aligns with intuition since the greatest acceleration m₁ can have is -g. The cord then accelerates m₂ upward at g while gravity acts downward, leading to a maximum upward acceleration of 2*g for m₁.</span>

tester [12383]

Answer:

Step-by-step explanation:

a) A diameter is a straight line that bisects a circle through its center. Line AD serves as a diameter.

The radius is half that of the diameter, which means AD/2 = AO or OD

A chord connects two points on the circumference of a circle but does not come through the center; it traverses segments of the circle instead. For instance, line FH is a chord

A tangent touches the circumference of the circle at one specific point and can contact any point along the circle's edge. Examples of tangent lines include AB and DE.

b) It's essential to know that the angles around a point or within a circle total 360°.

<EOH + <ECH = 360°

If <EOH = 131°

then <ECH = 360° - 131°

which results in <ECH = 229°

- <EFH is situated within the circle's circumference. Additionally, the angle at a circle's center is double that of the angle at the circumference. Therefore, since <EOH is at the circle’s center, <EFH = <EOH/2

Thus, <EFH = 131/2

so <EFH = 65.5°

c) Since AB = DE, it follows that <AB = <DE (equal and opposite angles). Given <AOB = 20°, then <DE = 20°

d) According to the illustration, <GFD = <GLD

If <GFD = 126°, then <GLD will likewise be 126°

e) Let HK = x+4, FK = x+14, GK = x, and CK = x+32

From the figure, we have CG = CK + KG

This means CG = x+32+x

leading to CG = 2x+32

Also, FH = FK + HK

So, FH = x+14+x+4

thus FH = 2x+18

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 29% each week. The following function represents
AnnZ [12381]

Step-by-step answer:

The base of the exponential function is set at 1.29 for a period of 7 days, which is expressed as

f(x) = 86*(1.29)^x

To determine the daily rate, divide the variable x by 7 (keeping x as the number of weeks), resulting in

f(x) = 86*1.29^(x/7)

Applying the exponent rule, b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x

we can simplify by setting b=1.29, a=7 to arrive at

f(x) = 86*(1.29^(1/7))^x

f(x) = 86*(1.037)^x since evaluating 1.29^(1/7) yields approximately 1.037

Rounding 1.037 to 1.04 gives a (VERY) rough estimate function

f(x) = 86 * (1.04^x)

1.04 is only an approximation because 1.04^7 is expected to return 1.29, it actually results in 1.316; meanwhile, 1.037^7 returns 1.2896, which is much closer to 1.29.
