Write an equation of the horizontal line through the point (7 , -5).
NNADVOKAT [17]

Equation of the horizontal line through  (7 , -5)

Horizontal line is a slope of 0, so y=constant.

Answer: y = -5

Slope -2  through (-4 , -5)

Point slope form of line slope m thru (a,b) is y-b = m(x-a)

y - -5 = -2 (x - -4)

y + 5 = -2x - 8

Answer: y = -2x - 13

check: slope is right, -2(-4) - 13 = 8 - 13 = -5, good

Find the magnitude and direction (in degrees) of the vector. v = ‹ - sqrt(7)/9, - sqrt(2)/3 ›
Sliva [168]
The magnitude is given by:
 lvl = root ((- root (7) / 9) ^ 2 + (- root (2) / 3) ^ 2)
 lvl = 0.555555556
 The address is given by:
 cos (theta) = (- root (7) / 9) / (0.555555556)
 Clearing theta:
 theta = acos ((- root (7) / 9) / (0.555555556))
 theta = 121.95 degrees
 Answer:
 
The magnitude and direction (in degrees) of the vector are:
 
lvl = 0.555555556
 
theta = 121.95 degrees

Give an example of an exponential function that includes the following transformations: o Vertical Compression o Reflection in t
mojhsa [17]

Step-by-step explanation:

A transformation may be defined as taking a basic function and then changing it slightly with the predetermined methods.  This changes will cause the required graph of that function to shift, move or stretch, which depends on the type of the transformation.

For example:

Let a function be : $f(x)= B^x$

For any constants m and n, the function $f(x)= B^{x+m}+n$  shifts the parent function.

- vertically n units and in same direction of the sign of n.

- horizontally m units and towards the opposite direction of the sign of m.

- The y-intercept becomes ($0, b^m+n$)

- The horizontal asymptote becomes y = n.

- the reflection about x -axis becomes $f(x)=- B^x$

Which is the best first step to write this in standard form?
goldenfox [79]

Answer:

<em>Set the function equal to 0</em>

Step-by-step explanation:

<u>Standard Form of the Quadratic Equation</u>

The form

ax^2+bx+c=0

is called the standard form of a quadratic equation. It can be clearly identified the terms of a second-degree polynomial equated to 0.

The equation is given in the form:

2(x-4)^2-3=8

And we need to operate the expression to make it look like a standard form. The first logical step should be to set the function equal to 0 and then start to operate the resulting expression. It can be done by subtracting 8 on both sides of the equation:

2(x-4)^2-3-8=0

Answer: Set the function equal to 0
