The following graph is the result of applying a sequence of transformations to the graph of one of the six basic functions. Iden

stellarik [79]

Answer:

The basic quadratic function is f(x) = x²

The equation of the graph is y = (x - 3)² - 1

Step-by-step explanation:

* Lets explain how to solve the problem

- The graph is a parabola which oped upward

∵ The function is represented by a parabola

∴ The graph is a quadratic function

∴ The basic quadratic function is f(x) = x²

- The vertex of the basic quadratic function is (0 , 0)

∵ From the graph the vertex of the parabola is (3 , -1)

∵ The x coordinate of the basic function change from 0 to 3

∴ The basic function translate 3 units to the right

- If the function f(x) translated horizontally to the right by h units,

then the new function g(x) = f(x - h)

∵ f(x) = x²

∴ The new function g(x) = (x - 3)²

∵ The y-coordinate of the basic function change from 0 to -1

∴ The basic function translate 1 unit down

- If the function f(x) translated vertically down by k units, then the

new function g(x) = f(x) - k

∵ g(x) = (x - 3)²

∴ The new function h(x) = (x - 3)² - 1

∵ h(x) = y

∴ The equation of the graph is y = (x - 3)² - 1

# <em>Note</em>: you can write the equation in general form by solve the

bracket of power 2

∵ (x - 3)² - 1 = (x)(x) - (2)(3)(x) + (3)(3) - 1 = x² - 6x + 9 - 1 = x² - 6x + 8

∴ y = x² - 6x + 8

The blood mass of a mammal is proportional to its body mass. A rhinoceros with body mass 3000 kilograms has blood mass of 150 ki

coldgirl [10]

Answer:

The equation which equates the two is M = $\frac{B}{20} = 0.05B$

A human with a body mass of 80 kilograms will have a blood mass of 4 kilograms.

Step-by-step explanation:

It is said that the blood mass is proportional to the body mass.

We can say that the blood mass of a mammal is M, and that the body mass of a mammal is B.

Since the two are proportional we can write

M ∝ B , or M = kB where k is the constant of proportionality.

Using the given values for a rhinoceros we can write

150 = k × 3000

Therefore k = $\frac{150}{3000} = \frac{1}{20} = 0.05$

Therefore the equation which equates the two is M = $\frac{B}{20} = 0.05B$

A human with a body mass of 80 kilograms will have a blood mass of

= $\frac{80}{20} = 4 kilograms$

Sales tax in Birmingham, AL, is the highest in the nation at 10 percent. Pete paid $9.44 in sales tax for an item in Birmingham,

N76 [4]

The answer is $94.40 because he paid 9.44 in sales tax and you need to multiply that by 10 since sales tax is 10%. So, you will get a result of $94.40. You could also check this by multiplying 94.40 by 0.10 and if you get 9.44 (which you do) then it is correct.
