If AB is translated right 5 units and down two then both points are translated by that amount.

A currently is (-5, 2)

x=-5 and y=2

Since youre going right by five your x value will increase by 5 so the point will instead be at x=0

Since youre going down by two your y value will decrease by 2 so the point will instead be at y=0

3. How would you explain to someone who has not yet studied trigonometry the
difference between an identity and an equation?

Answers

Answer:

Solving an equation means finding the value or values for which the two expressions are equal. ... An identity is an equation which is always true, no matter what values are substituted.

What is the difference between trigonometric identity and equation?

A trig identity is an equation that is true for all values of x;

For example:

sin²x + cos²x will always equal 1 no matter what the value of x.

There are some equations considered to be identities that are in fact not true all the time.

tan(2x) = 2tanx/(1 - tan²x) is not true when x = π/2 (right side is undefined).

A conditional equation is one that is true for a subset of the real numbers, i.e. for certain values of x, but not all.

For example:

sin²x - 1 = 0 is only true for some values of x.

sin²x = 1

sinx = ±√(1) = ±1

sinx = 1 or sinx = -1

x = sin-11 or x = sin-1(-1)

x = π/2 + 2kπ, k any integer or x = 3π/2 + 2kπ, k any integer (this can be condensed, but left this way for emphasis).

Determine the quadratic curve of best fit for the data. Then estimate what the value of will be when = −4. {(−3,2), (0,5), (1,7.3), (−1,3.3), (−6,5), (−7,7.3)} Answer choices 4.3 5.3 3.3 2.3

Answers

Answer:

The value of 'y' when x = -4 is 2.3

Step-by-step explanation:

Curve of best fit can be found by plotting the points on MS Excel and drawing a curve that goes through the points as shown in the attached graph

The equation that approximate the curve from which the y-value at a x-value of -4 can be estimated is found as follows

The general equation for a quadratic equation is y = a·x² + b·x + c

Therefore, we get;

2 = a·(-3)² + b·(-3) + c

2 = 9·a - 3·b + c

5 = 0·a + 0·b + c

5 = c

7.3 = 1·a + 1·b + c = a + b + 5

7.3 = a + b + 5

2.3 = a + b

2 = 9·a - 3·b + 5

-3 = 9·a - 3·b

Solving gives;

a = 13/40, b = 79/40

The equation of the quadratic curve is therefore;

y = (13/40)·x² + (79/40)·x + 5

When x = -4, we get;

y = (13/40)·(-4)² + (79/40)·(-4) + 5 = 2.3

When x = -4, y = 2.3

Plotting the points on MS Excel we find from the attached graph that the estimated value of 'y' when x = -4 is as calculated (2.3).
