Help me find y.......

Mathematics
1 answer:
erastova [34]3 years ago
3 0

Answer:

  y ≈ 240.3 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation between an angle and the sides adjacent and opposite is ...

  Tan = Opposite/Adjacent

In this triangle, the interior angle at lower right is the same as the one marked at upper left: 31°. y is the side opposite that angle, and 400 ft is the side adjacent. Then the relation is ...

  tan(31°) = y/(400 ft)

Multiplying by 400 ft gives ...

  y = (400 ft)·tan(31°) ≈ 240.3 ft

_____

The triangle interior angle at lower right and the angle marked 31° are "alternate interior angles" relative to the transversal marked x and the (parallel) horizontal lines in the figure. Alternate interior angles always have the same measure.

In geometry problems like this one, it means the angle of elevation (above the horizontal) is equal to the angle of depression (below the horizontal).

the graph of f(x) is shown below. what are the values of a, b, c, and d in the definition of f(x) below? (graph and definition o
Otrada [13]

Answer:

Step-by-step explanation:

For the given piecewise function,

Let the equation of the segment AB is,

y = ax + 7 where x < -2

Since a point (-2, 3) lies on the given line,

3 = a(-2) + 7

3 - 7 = -2a

a = 2

Therefore, f(x) = 2x + 7 when x < -2

For the segment BC,

f(x) = 3 where -2 ≤ x ≤ 2

For the segment CD,

f(x) = bx + 9

Since a point (2, 3) lies on this segment,

f(2) = 2b + 9 = 3

2b = 3 - 9

b = -3

Therefore, equation of segment CD will be,

f(x) = (-3)x + 9   where x > 2

Will give brainly .Which statements are true regarding undefinable terms in geometry? Check all that apply.
babymother [125]

The true statements about terms in geometry that are undefinable are;

  • A point has no length or width
  • A point indicates a location on the coordinate plane
  • A line consists of an infinite set of points.
  • A plane consists of an infinite set of points.

<h3>How can the true statements be found?</h3>

Three undefinable terms in geometry are;

1) Point

2) Line

3) Plane

The above terms do not have a formal definition but they can be described based on their properties.

The other geometric terms are defined based on the above undefinable terms.

A point can be described as a location in space that is dimensionless and can be specified on the coordinate plane as an ordered pairs (x, y).

True statements about a point are therefore;

  • A point has no length or width
  • A point indicates a location on the coordinate plane

A line is infinitely long, that has no beginning or end. It has one dimension, with no thickness or height.

Given that a point is dimensionless, a line can be considered a set of points.

A true statement is therefore;

  • A line consists of an infinite set of points.

A plane is a two dimensional geometric figure that have infinite length and width.

An infinite set of lines that forms a two dimensional figure can be used to describe a plane.

The true statement with regards to a plane is therefore;

  • A plane consists of an infinite set of points.
