The value at which acceleration is zero is t = 5/3

Acceleration is defined as the rate at which velocity changes with time, in terms of both speed and direction

Given: the equation of motion, velocity, s = t⁶ - 2t⁵

Since acceleration is the rate at which velocity changes with time.  You need to differentiate the velocity with respect to time. Thus:

ds/dt = 6t⁵ - 10t⁴                  (Note: ds/dt is the acceleration)

Also, acceleration is equal to zero. That is:

6t⁵ - 10t⁴ = 0

6t⁵ = 10t⁴

6t = 10

t = 10/6 = 5/3

Therefore, the value of t at which acceleration is zero is t = 5/3

Answer:

  f(x) = 3(x +1)² +2

Step-by-step explanation:

You want the equation in vertex form of the parabola 3x² after its vertex is translated to (-1, 2).

The given form is the "vertex form" of the equation for a parabola. That is, in the form ...

  f(x) = a(x -h)² +k

the value of 'a' is the leading coefficient, the scale factor, and the values of h and k are the x- and y-coordinates of the vertex.

Given that the scale factor of the desired parabola is a=3, and the desired vertex is (h, k) = (-1, 2). we can fill in these values in the equation to get ...

  f(x) = 3(x -(-1))² +2

  f(x) = 3(x +1)² +2

The distance between the points, (-8, -2) and (12, 10), is 23.3

From the question, we are to determine the distance between the two given points.

From the given information,

The points are (-8, -2) and (12, 10)

The distance between two points in given by the formula

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Where d is the d is the distance between the points

Thus,

d = √[(12 - (-8))² + (10 - (-2))²]

d = √[(12 + 8)² + (10 + 2)²]

d = √[(20)² + (12)²]

d = √[400 + 144]

d = √[544]

d = 23.3

Hence, the distance is 23.3

Answer:

∠W = 36.6°

Step-by-step explanation:

Hello!

If angles are complementary, it means that they add up to 90°.

Since the measure of Angle X is 53.4, we can find measure of Angle W by subtracting 53.4 from 90.

The value of W is 36.6°.

It will take approximately 54 years for the element to decay from 18 grams to 2 grams at a rate of 4% per year.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

To determine how long it takes for an element to decay from 18 grams to 2 grams, you can use the formula:

t = (ln(A/B)) / (-r)

where:

t is the time it takes for the decay to occur

A is the initial amount of the element, in this case 18 grams

B is the final amount of the element, in this case 2 grams

r is the decay rate, in this case 4% per year

Plugging these values into the formula gives you:

t = (ln(18/2)) / (-0.04)

t = (ln(9)) / (-0.04)

t = (2.1972) / (-0.04)

t = -54.30

Hence, It will take approximately 54 years.

The bicycle wheel performs 10 revolutions every minute

A revolution in math is a full rotation, or a complete, 360-degree turn. In a 360-degree rotation, the object starts and ends in the same position. A mathematical revolution can be visualized when a top spins.

The bicycle wheel makes 1 complete revolution which is equal to the circumference of the wheel = πD

but D =  diameter = 42 inches, converting inches to feet

12inches is 1 foot, then 42 inches = 42/12 = 7/2 inches

Also circumference = 22/7 x 7/2 = 11 feet/rev

Also if the rider travelled 110 feet per minute.

Then the wheel's revolution per minute = 110/11
                                                                   = 10 rev/minute

In conclusion the bicycle wheel revolves 10 times every minute

The percentage reduction of the jacket is 20 percent.

Percentage decrease or reduction means subtracting a given percentage of a value from the original value.

Therefore, the jacket cost 80 dollars and it is reduced to 64 dollars.

The percentage reduction of the jacket can be calculated as follows:

% reduction = (Decreased Value / Original Value) × 100

Decreased value = 80 - 64 = 16

Original Value = 80

% reduction = 16 / 80 × 100

% reduction = 1600 / 80

In the given question we have to prove ∆GHJ congrurnce ∆KLM.

Given that: ∠G≅∠K, ∠J≅∠M, [tex]\over{HJ}[/tex] ≅ [tex]\over{LM}[/tex].

As given that;

∠G≅∠K

The probability that their babies would have brown wool will be 25%.

When two or more alleles for the same characters are present at the same loci on homologous chromosomes, a cell, a nucleus, or a single organism is said to be heterozygous. In contrast to homozygous, where the alleles are identical, it signifies that the alleles that code for the same gene or characteristic are different.

Given, the two-parent sheep would need to have heterozygosity for their genotype if we were to assume straightforward Mendelian genetics. Black would not be dominant in this situation; instead, the parents would be, shall we say, Rr for color. Imagine that each parent can only contribute one allele (either the R or the r). If both should chance to deliver the r, the child would be black.

Therefore, 25% of the following generation's children are likely to be black. There would be a 25% probability of a homozygous dominant offspring, a 50% chance of a heterozygous offspring, and a 25% chance of a homozygous recessive offspring if you filled out a Punnett square for this issue. Since white is the dominant allele in this situation, both the homozygous dominant allele, which accounts for 75% of the possibilities and the heterozygous child will be white. Since two recessive alleles are required to manifest the recessive phenotype, the remaining 25% of people are black.
