Determine the truth value of each of these statements if the domain of each variable consists of all real numbers.a) ∀x∃y(x2 = y)

Answers

The statement ∀x∃y(x² = y) is true for all real numbers, as for each real number x, there exists a real number y such that x² = y.

How to determine the truth value of a statement?

The statement ∀x∃y(x² = y) is true as explained below:

For every real number x, there exists a real number y such that x² = y.

For example:

If x = 2, then y = 4 because 2² = 4.

If x = -3, then y = 9 because (-3)² = 9.

Since you can always find a real number y that satisfies the equation x² = y for any real number x, the statement is true for all real numbers in its domain.

The statement is true. If x and y are both real numbers, the statement is:

"for every x, there exist y such that x^2=y"

This is true, because you can pick any real number, square it, and obtain another real number, y. The relation is not surjective, i.e. we will not use all possible values for y, but it doesn't matter. The statement is only asking to find a value for x^2, which we can always do.

Find the perimeter of trapezoid WXYZ with vertices W(2, 3), X(4, 6), Y(7, 6), and Z(7,3). Leave your answer in simplest radical form.

Answers

Answer:

Perimeter = 11 + √(13)

Step-by-step explanation:

To find the perimeter of WXYZ we need to find the length of all four sides: WX, XY, YZ and WZ.

To find the length of each side, we can use the formula for the distance of two points:

distance = √((x_1 - x_2)^2 + (y_1 - y_2)^2)

So we have that:

WX = √((2 - 4)^2 + (3 - 6)^2) = √(13)

XY = √((4 - 7)^2 + (6 - 6)^2) = 3

YZ = √((7 - 7)^2 + (6 - 3)^2) = 3

WZ = √((2 - 7)^2 + (3 - 3)^2) = 5

The perimeter is:

Perimeter = WX + XY + YZ + WZ

Perimeter = √(13)  + 3 + 3 + 5 =11 + √(13)

Find the sum of the measures of the INTERIOR angles in 36-gon polygon

Answers

Answer: 6120

Step-by-step explanation:

The equation for the interior angles of a polygon is (n-2)180. So using the equation, (36-2)180=(34)180=6120.

Answers

Answer:

  1.896

Step-by-step explanation:

You can answer this just using your number sense.

  \log_7{(40)}\approx 1.896

You know that 49 = 7², so log₇(49) = 2. The log function has a fairly small slope, so log₇(40) will not be far from 2.

_____

If you want to use your calculator, you can use the "change of base formula".

  log₇(49) = log(49)/log(7) ≈ 1.602060/0.845098 ≈ 1.896

How many solutions does the system of equations below have y=3x+2 y-2x=4

Answers

it has one solution
(2,8)
x=2
y=8

Answer:

Only one solution.

Step-by-step explanation:

y = 3x +2

y -2x =4

y - 2x = 4

=> y = 2x +4

y = 3x + 2

y = 2x + 4

Since both equations are not the same, so the answer cannot be "infinitely many solutions".

They both intersect each other 1 point, so it cannot be "no solutions".

So the answer is "Only 1 solution".
