The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.

Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.

a = dv/dt

We have the following informations are available,

Initial velocity, v(0) = 4i

Initial position, r(0) = 2j

Acceleration at any time "t",

a(t) = tk

we have to determine the value of v(t) and r(t).

As we know, a(t) = dv(t)/dt = tk

integrating the above equation ,

v(t) = ∫tk dt = ( t²/2 )k + c

at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i

=> c = 4i

So, v(t) = ( t²/2 )k + 4i

Also, velocity is calculated by derivative of postion (r) with respect to time.

=> v(t) = dr(t) /dt

=> r(t) = ∫ v(t) dt

=> r(t) = ∫ ( t²/2 )k dt

integrating value of the right hand side,

r(t) = ( t³/2×3 )k +d

= (t³/6)k + d

At t = 0, r(0) = (0/6)k + d

=> r(0) = d = 2j

so, r(t) = (t³/6)k + 2j

Hence, the required position and velocity are

(t³/6)k + 2j and ( t²/2 )k + 4i.

Peter will need approximately 169169 centimetres of red ribbon to make the "x" on his flag. Rounded to the nearest centimetre, this is 169200 centimetres.

To find the length of the red ribbon needed to make the "x" on the flag, we need to find the length of the diagonal of the square. The diagonal of a square is a line segment that connects two opposite corners of the square and passes through the centre of the square.

The diagonal of a square can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In the case of a square, the two shorter sides of the right triangle are equal in length to the sides of the square, so the Pythagorean theorem can be written as:

[tex]a^2 + a^2 = c^2[/tex]

Where "a" is the length of a side of the square and "c" is the length of the diagonal.

To find the length of the diagonal of Peter's flag, we can substitute 121212 for "a" in the equation above:

[tex](121212)^2 + (121212)^2 = c^2[/tex]

Solving for "c" gives us:

c = 169169 centimetres

Therefore, Peter will need approximately 169169 centimetres of red ribbon to make the "x" on his flag. Rounded to the nearest centimetre, this is 169200 centimetres.

Answer: the answer is £12.

Step-by-step explanation:

To solve this problem, we can set up an equation to represent the information given in the problem. Let's call the amount of money Hasim had at the beginning of the day x.

We know that Hasim gave his brother 1/3 of his money, so we can represent that with the equation:

x / 3 = y

Where y is the amount of money Hasim gave to his brother.

We also know that Hasim spent £12 on a present for his sister, so we can subtract that amount from x to find the amount of money he had left:

x - 12 = z

Where z is the amount of money Hasim had left after buying the present.

Finally, we are told that the amount of money Hasim had left is half of what he had at the beginning of the day, so we can represent that with the equation:

x / 2 = z

Now we have three equations that all involve the variable x. We can solve for x by substituting the first equation into the second and third equations:

x / 3 = x - 12

x / 2 = x / 3

Solving these equations, we find that x = 36.

This means that Hasim had £36 at the beginning of the day, and gave his brother £36 / 3 = £<<36/3=12>>12.

By understanding the property of circles, it can be concluded that the measurement of dimension A is 1 1/4".

Circle is a geometric shape in which all the constituent points are at a certain distance from the center point. A circle has a diameter that shows the maximum distance between any two points of the circle. Whilst the radius is half the diameter.

Now we take a look at the picture thoroughly.

The width of the manufactured part =

the diameter of the circle on the far left = 2 * the radius

                                                                  = 2 * 1"

                                                                  = 2"

This value is equal to the sum of A, the radius of the circle at the very bottom (1/2"), and the space between this circle and the edge (1/4"). We write it down mathematically:

2" = A + 1/2'' + 1/4''

2" = A + 3/4"

A = 2" - 3/4"

  = 1 1/4"

Thus the measurement of dimension A is 1 1/4".

The rate of increase of the radius of the balloon at the instant when the radius is 30 cm is 0.0167 cm/min and when the radius is 60 cm, it is 0.0021 cm/min.

(a) At the instant when the radius of the balloon is 30 cm, the rate of increase of the radius of the balloon is

Rate of Increase of radius = (Change in Volume/ Change in Time) / (4/3 × π × (radius)^3)

= (800 cm3/min) / (4/3 × π × (30 cm)^3)

= 0.0167 cm/min

(b) At the instant when the radius of the balloon is 60 cm, the rate of increase of the radius of the balloon is

Rate of Increase of radius = (Change in Volume/ Change in Time) / (4/3 × π × (radius)^3)

The logarithmic expression [tex]\log {750}[/tex]  is the lograrithm with base 10 of 750 and it's value is approximately equal to 2.8751


Logarithms are expressed mathematically as [tex]\log_{x}b=y[/tex] where [tex]x[/tex] denotes the base of the logarithm, [tex]b[/tex] denotes a number and [tex]y[/tex] denotes the exponent. The above expression can also be written as [tex]x^{y}=b[/tex]
We will be using two logarithmic properties in this question:

The first one is, [tex]log(mn) = logm + logn[/tex]

And the second one is, [tex]log(m^{n}) = n*logm[/tex]

Whenever the base in the question is not shown then it is assumed to be 10 in mathematics.

∵ This is a base 10 logarithm, we must determine a value of [tex]y[/tex] for expression [tex]10^{y} = 750[/tex]
Since there is no other value of log given we have to use the calculator.

If the value of [tex]log_{}3[/tex] and [tex]log5[/tex] is given then we can solve the question:

[tex]log750 = log_{10} 750[/tex]

The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.

In another word, a logarithm is a different way to denote any number.

As per the given expressions,

u = ln x and v = ln y

Take anti-log as

x = [tex]e^{u}[/tex] and y = [tex]e^{v}[/tex]

Thus, x² = [tex]e^{2u}[/tex] and y⁵ = [tex]e^{5v}[/tex].

Multiply both as

x²y⁵ =  [tex]e^{2u}[/tex][tex]e^{5v}[/tex]

Take logarithms on both sides,

ln(x²y⁵) = ln( [tex]e^{2u}[/tex][tex]e^{5v}[/tex])

By log property that ln(A x B) = lnA + lnB

ln(x²y⁵) = ln  ([tex]e^{2u}[/tex]) + ln([tex]e^{5v}[/tex])

What is a function?

A function is a relation between a set of inputs (also called the domain) and a set of outputs (also called the range) such that for each input, there is exactly one output. A graph of a function is a visual representation of the relationship between the inputs and outputs, with the inputs represented on the x-axis and the outputs represented on the y-axis.

A curve can be a function if it meets the definition of a function, which states that for each input (x value), there is exactly one output (y value). In other words, no two points on the curve have the same x-coordinate but different y-coordinates.

The function h(m) = (1/2)*m + (6 + 1/2) represents the height (on feet) of the giraffe as a function of the number of months, m.

We want to find the difference in the height between month 11 and month 2, then we need to find:

difference = h(11) - h(2)

We can directly calculate this:

difference = [ (1/2)*11 + (6 + 1/2)] - [(1/2)*2 + (6 + 1/2)]

difference = (1/2)*11 - (1/2)*2 = (1/2)*(11 - 2) = (1/2)*(9) = 9/2

Using Pythagoras theorem, the hypothenuse is equal 4 units

Pythagoras theorem states that in a right triangle, the square of the length of the longest side (the hypotenuse) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be expressed as a²+ b² = c², where a and b are the lengths of the two shorter sides, and c is the length of the hypotenuse.

The length of the third side is the hypothenuse and we can use Pythagoras theorem to find that.

a²+ b² = c²

3² + (√7)² = c²
