Kay's mother's age is six more years than twice Kay's age. The sum of their ages
is 81. Find both of their ages.

Answer:

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

I cant draw you a picture but it will be one right triangle inside the other where the vertical tower will be one leg common to 2 triangles and the base of the 2 triangles will be x and x+10 metres.

Tan 30 = h/ (x + 10)

tan 45 = h/x        where h is the height of the tower.

From the second equation  x = h / tan45

Substituting in the first equation;

tan30 = h / (h/tan45 + 10

Tan 30 = 1/ √3 and tan 45 = 1 so

1/ 1.732 = h/ (h + 10)

0.5774 = h/(h + 10)

h = 0.5774h + 57.74

0.4226 h = 57.74

h = 136.6 m to nearest tenth.

A sequence is the pattern or rule that guides the creation of a set. The most common sequence are the arithmetic and the geometric sequence.

The complete question illustrates that we build a sequence of number.

Let the n term of the sequence be [tex]T_n[/tex].

2 times 3 less than the previous number means:

[tex]T_n = T_{n-1} - 2 \times 3[/tex]

Where:

[tex]T_n \to[/tex] The current number

[tex]T_{n-1} \to[/tex] The previous number

Assume the first number starts with 0, the next numbers will be:

[tex]T_2 = 0 - 2 \times 3 = -6[/tex]

[tex]T_3 = -6 - 2 \times 3 = -12[/tex]

[tex]T_4 = -12 - 2 \times 3 = -18[/tex]

So, the sequence is:

0, -6, -12, -18.....

Assume the first number starts with 3, the next numbers will be:

[tex]T_2 = 3 - 2 \times 3 = -3[/tex]

[tex]T_3 = -3 - 2 \times 3 = -9[/tex]

[tex]T_4 = -9 - 2 \times 3 = -15[/tex]

So, the sequence is:

3, -3, -9, -15.....

Answer: False

If two lines intersect, then they intersect at one point only, so it makes no sense to mention a second point. This is assuming that we're not talking about two lines intersecting infinitely many times (i.e. one line overlapping another perfectly).

Answer:

B. The distribution is not symmetrical.

Step-by-step explanation:

In order for the distribution to be symmetrical, the median line (line in the box) should be in the center. This box plot is more positvely skewed.

Answer:

A rhombus is a geometric figure that lies in a plane. It is defined as a quadrilateral all of whose sides are congruent. It is a special type of parallelogram, and its properties (aside from those properties of parallelograms) include:

Its diagonals divide the figure into 4 congruent triangles.

Its diagonals are perpendicular bisectors of eachother.

If all of a rhombus' angles are right angles, then the rhombus is a square.

Answer:yes it does have perpendicular lines

Answer:

  1. (f+g)(x) = 2x^2 +4x +2

  2. (f -g)(x) = -2x^2 +4x -4

  5. (f+g)(x) = x^2 +2x -1

  6. (g -f)(x) = x^2 -2x -1

Step-by-step explanation:

None of these are compositions. They are only sums or differences.

  (f±g)(x) = f(x) ± g(x)

__

1. (f+g)(x) = f(x) +g(x) = (4x -1) +(2x^2 +3)

  (f+g)(x) = 2x^2 +4x +2

__

2. (f -g)(x) = f(x) -g(x) = (4x -1) -(2x^2 +3)

  (f -g)(x) = -2x^2 +4x -4

__

5. (f +g)(x) = f(x) +g(x) = (2x) +(x^2 -1)

  (f+g)(x) = x^2 +2x -1

__

6. (g -f)(x) = g(x) -f(x) = (x^2 -1) -(2x)

  (g -f)(x) = x^2 -2x -1
