What is the square root of 18, square root of 50 and square root of 27x^3y?

Answers

Answer 1
Answer: √(18)=√(9\cdot2)=\sqrt9\cdot\sqrt2=3\sqrt2\n\n√(18)\approx4.24\n\n√(50)=√(25\cdot2)=√(25)\cdot\sqrt2=5\sqrt2\n\n√(50)\approx7.07\n\n√(27x^3y)=√(9\cdot3x^2xy)=√(9x^2)\cdot√(3xy)=3x√(3xy)

Find the coordinates of the intersection of the diagonalsof parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2). Hint: what do we know about
the diagonals of a parallelogram?

Answers

The coordinates of the intersection of the diagonals  of parallelogram XYZW is at (6, 4).

Parallelogram

A parallelogram is a quadrilateral in which opposite sides are parallel and equal. The diagonals of a parallelogram bisect each other.

Given parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2).

The equation of diagonal XZ is:

  • y-2=(6-2)/(10-2) (x-2)\n\ny=0.5x+1

The equation of diagonal YW is:

  • y-6=(2-6)/(9-3) (x-3)\n\ny=-(2)/(3) x+8

The point of intersection is at:

0.5x + 1 = (-2/3)x + 8

x = 6. Hence y = 4

The coordinates of the intersection of the diagonals  of parallelogram XYZW is at (6, 4).

What is the half of 62

Answers

The half of the given term 62 is 31.

How to divide a quantity into finite equal parts?

Suppose that there are k things which are to be divided in P parts, then

will give the amount that each one of P parts would get from k, that will make equal distribution of k things in P parts.

The half of 62 can be calculated by dividing the given term by 2.

62 / 2 = 31

Thus, the half of the given term 62 is 31.

​ a(1)= 3 5 ​ a(n)=a(n−1)⋅(−9) ​ What is the 3^{\text{rd}}3 rd 3, start superscript, start text, r, d, end text, end superscript term in the sequence?

Answers

Answer: -630

Step-by-step explanation:

Given the nth term of a sequence;

​a(n)=a(n−1)⋅(−9) and the first term of the sequence a(1) as 35, the third term of the sequence can be gotten by using the formula at when n = 3

If n = 3 and a(1) = 35;

a(3) = 35(3-1)•(-9)

a(3) = 35×2×-9

a(3) = 70×-9

a(3) = -630

There the 3rd term of the series will give us -630 according to the nth term of the formula given.

Final answer:

The problem is about a recursive sequence where each term is the previous term multiplied by -9. After applying this rule twice, it is found that the 3rd term of the sequence is 243.

Explanation:

The problem provided indicates a recursive sequence, where each term is based on the previous term. The sequence is defined as a(1) = 3 and a(n) = a(n - 1) ⋅ (−9), which essentially means that each subsequent term is the previous term multiplied by -9.

To find the 3rd term, we apply this rule twice starting from the first term:

a(2) = a(1) * (-9) = 3 * (-9) = -27

a(3) = a(2) * (-9) = -27 * (-9) = 243

Therefore, the 3rd term of the sequence is 243.
