## Eric states that the slopes of perpendicular lines are opposite reciprocals (i.e. that the slope of one is equal to the negative of the reciprocal of the other), and Aviva states that the product of the slopes of perpendicular lines is −1. Who is correct? Why? Explain your reasoning with an example. If one of the lines is vertical and the other one is horizontal, how would your answer change?

[ad_1]

### Answered by answersmine AT 22/10/2019 – 03:50 AM

Eric’s statement is correct that the slopes of the perpendicular lines are opposites reciprocal with each other compared to Aviva’s. Aviva’s statement is correct but is not usually the case. An example is that when you are given these functions such as y = -2x + 3 and y = 1/2x + 4. The coefficients of the x variable are 2 and negative 1/2. The slopes must be in opposite signs so that the two functions will intersect at a common point and will form a ninety degree angle. This is the very basis of a perpendicular line because if both lines have the same slopes, then both lines are just parallel with each other, they cannot intersect.

## If an angle formed by perpendicular lines has a ray in its interior coming from the vertex of the right angle, what do we call the relationship of the two angles? Select one: a. Right angles b. Corresponding angles c. Alternate interior angles d. Complementary angles

[ad_1]

### Answered by answersmine AT 22/10/2019 – 04:13 AM

The ray divides one of the right angles into two smaller angles, but we are not told whether or not the smaller angles are equal or unequal.  These two angles are complementary angles.  Why? Because their sum is 90 degrees (definition of complementary angles).

## Determine which of the following equations are perpendicular to each other. I. y=-3x+2 II. -3x+2y=1 III. x+3y=1 IV. y+1/3x+9 A. I and III B. I and IV C. II and IV D. None of these equations are perpendicular.

[ad_1]

Write each equation in y = mx + b form so that you can compare the slopes.
Perpendicular slopes are opposite reciprocals.
For example: 2/3 and – 3/2; 4/5 and -5/4; 1/2 and -2

I. y = -3x + 2                 m = -3
II. y = 3/2 x + 1/2          m = 3/2
III.  y = – 1/3x  + 1/3      m = -1/3
IV. y = 1/3x + 9             m = 1/3          (I assuming this one had a typo in it                                                                   since there is no equal sign.)
LETTER B is the answer I & IV

## What is the equation that is perpendicular and passes through 8,3

[ad_1]

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

Answer:

False

Step-by-step explanation:

Suposse that we are given a function f(x) and a constant value h.

1. Case:

If we take the function g(x)=f(x)+h, then the graph of the function g(x) will be the graph of the funcion f(x) moved up or down.

2.Case:

If we take the function g(x)=hf(x), then the graph of the function g(x) will be the graph of the function f(x) just taller or shorter.

3.Case:

If we take the function g(x)=f(x-h), then the graph of the function g(x) will be the graph of the fuction f(x) moved horizontally.

4. Case:

If we take the function g(x)=f(hx), then the graph of the function g(x) will be tha graph of the function f(x) wither or thiner.

For example:

If we take f(x)=sin(x) and h=2. Then, if we take g(x)=sin(2x) then f(0)=g(0)=0, which means that the graph of the functiction is not moved up or down. However, f(π/2)=sin(π/2)=1 and g(π/2)=sin(π)=0 which gives us a hint that the graph of the function became thiner.

Vi and Vf are the initial and final velocities, respectively. g is the
deceleration due to gravity.

Substituting
the known values,

D
= ((700 m/s)2 – (0 m/s)2) / (2(-9.8 m/s2))

D = 25000 m

Thus,
the maximum height is 25000 m.

For
