The type parameters act as placeholders for the types of the arguments passed to a method. The type parameter names throughout the method declaration must match those declared in the type parameter list.
Pass an array as a pointer to pass it as a parameter to a function (since it is a pointer). For instance, the following method sets array A's first n cells to 0.
In C++, an entire array cannot be provided as an argument. However, by mentioning the array's name, you can supply a pointer to an array without an index.
Only the array name is supplied as a parameter to pass a full array to a function. calculateSum(num), result But take note of how [] is used in the function specification. This tells the compiler that you are handing the function a one-dimensional array.
When we provide an array to a function as an argument, we are actually passing the address of the array in memory, which is the reference. To pass an array to a function, simply pass the array as the function's parameter (like normal variables).

Peter is making an "x marks the spot" flag for a treasure hunt. The flag is made of a square white flag with sides of 121212 centimeters. He will make the "x" by stretching red ribbon diagonally from corner to corner. How many centimeters of ribbon will peter need to make the "x"? round your answer to the nearest centimeter. Centimeters.
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.

Calculate the surface area to volume ratio of each prism
For shape A the area to volume ratio is 101: 66
For shape B the area to volume ratio is 197117.7 : 207034
For shape C the area to volume ratio is 202.71 : 529.2
What is area and volume?The area is the amount of space occupied by a two-dimensional flat object in a plane. Volume is defined as the space occupied by a three-dimensional object. The unit of area is in square units. The unit of volume is in cubic units.
For shape A, the area = 2(lh+lb+bh)
= 2( 2×12+12×5.5+5.5×2)
= 2 ( 24+ 66+ 11)
= 2 ( 101)
= 202m²
The volume of shape A = l×b×h = 2× 12× 5.5 = 132m³.
Therefore the ratio of area to volume of shape A = 202:132 = 101: 66
For shape B
The area of the cylinder = 2πr(r+h)
= 2×3.14× 28( 28+84.1)

A baby giraffe is about 612 feet tall at birth and grows about 12 foot per month for its first year. The function h=12m+612 represents the total height h of a baby giraffe for any number of months m within its first year. How much taller is the giraffe at the end of month 11 than at the end of month 2? write your answer as a whole number, fraction, or decimal.
4 and 1/2 ft taller is the giraffe at the end of month 11 than at the end of month 2.
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
And we can write 9 = 9 + 1, then:
difference=9/2 = (8 + 1)/2 = 8/2 + 1/2
difference= 4 + 1/2

Kala is putting money into a savings account. She starts with $750 in the savings account, and each week she adds $70. Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Kala has been adding money. Write an equation relating S to W. Then use this equation to find the total amount of money in the savings account after 11 weeks.
Answer:
$1520
Step-by-step explanation:
The total amount of money in the savings account after W weeks is equal to the initial amount of money, $750, plus the amount of money added each week for W weeks. We can represent this relationship with the following equation:
S = 750 + 70W
To find the total amount of money in the savings account after 11 weeks, we can substitute 11 for W in the equation above:
S = 750 + 70(11)
= 750 + 770
= 1520
Therefore, the total amount of money in the savings account after 11 weeks is $1520.
Answer:

It would take 23.45 years to double the investment of £100 with a compound interest rate of 3% to £200.
How to find the number of years to double an investment?Using the formula A = P(1 + r)^t
Initial amount of investment, P = 100
Final amount(double the investment), A = (2 x 100) = 200
Interest rate, r = 3% = 0.03

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.

question1 pls answer
Answer:
f(3) = 10
Step-by-step explanation:
given f(x) = 12/x + 6,
we want to find f(3)
to do so we plug in x = 3
so,
==> f(3) = 12/3 + 6
==> f(3) = 4 + 6
==> f(3) = 10
