Mathematics
1 answer:
serious [3.7K]3 years ago
4 0

Answer:

1: 233 m

2: 466 m

3: 241.87 m

4: 483.72

Step-by-step explanation:

The Pythagorean Theorem states that a^2 + b^2 = c^2, in which c is the hypotenuse (in this case,  PQ and RS).

1: 105^2 + 208^2 = 54289, square root of 54289 = 233

2: Since the area of the triangle makes up half of the rectangle, multiply the area by 2 to get 466

3: 120^2 + 210^2 = 58500, square root of 58500 is 241.87

4: Multiply by 2 to get 483.72

Which pair of undefined terms is used to define a Ray?
REY [17]

Answer:

The undefined terms which are used to define a ray is:

Point and a line.

Step-by-step explanation:

The undefined terms in coordinate geometry are:

Line, Points and Plane.

since a line do not have any length, Point has a location but no size.

A line has no width and it extends infinitely and is one dimensional.

and a plane extends infinitely in both the dimensions.

<em>Ray:</em>

<em>A ray is part of a line, has one fixed endpoint, and extends infinitely along the line from the endpoint.</em>

Hence, the undefined terms which are used to define a ray is:

Point and a line.

Find the output, k, when the input, t, is -7−7minus, 7.<br> k = 10t-19k=10t−19
sleet_krkn [62]

The value of k is -89

Explanation:

The given expression is k=10t-19

We need to determine the output k, when the input t is -7

<u>Output k:</u>

The value of the output k can be determined by substituting the input t=-7 in the expression k=10t-19

Thus, we have,

k=10(-7)-19

Multiplying the terms 10 and -7, we have,

k=-70-19

Simplifying, we get,

k=-89

Thus, the value of k is -89

NEED HELP ASAP!!!<br> thank you.
Alex17521 [72]

Answer:

See explanation

Step-by-step explanation:

Consider triangles ACM and BCM. In these triangles,

  • m\angle 3=m\angle 4 - given;
  • m\angle 1=m\angle 2=90^{\circ} - definition of perpendicular lines CM and AB;
  • \overline{CM}\cong \overline{CM} - reflexive property.

So,

\triangle ACM\cong \triangle BCM by ASA postulate (if one side and two angles adjacent to this side of one triangle are congruent to one side and two angles adjacent to this side of another triangle, then two triangles are congruent).

Two-column proof:

      Statement                                 Reason

1. m\angle 3=m\angle 4                          Given

2. CM\perp AB                        Given

3. m\angle 1=m\angle 2=90^{\circ}       Definition of perpendicular lines CM and AB

4. \overline{CM}\cong \overline{CM}          Reflexive property

5. \triangle ACM\cong \triangle BCM                       ASA postulate

Trigonometry<br> Special Right Triangles<br> Find the exact value of tan 30* + sin 90* + cot 60*.
fredd [130]

Answer:

1 + 2sqrt(3)/3

Step-by-step explanation:

tan(30) = sqrt(3)/3

sin(90) = 1

tan(60) = sqrt(3)

cot(60) = 1/sqrt(3) = sqrt(3)/3

sqrt(3)/3 + 1 + sqrt(3)/3

1 + 2sqrt(3)/3
