8_murik_8 [283]

Answer:

2.2

Step-by-step explanation:

To find a, you use a formula called the law of cosines:

The law of cosines tells us:

a^2 = b^2 + c^2 - 2bc cosA

So lets plug in the values:

a^2 = 4^2 + 3^2 -2(4)(3)cos(32)

a^2 = 25-24cos32

a^2 is roughly equal to 4.97

therefore a roughly equal to 2.2

Answer:

The function is

$f(x)=0.5x^3-3x^2+5.5x-2$

The graph is attached.

Step-by-step explanation:

We have a function g(x) and we need to graph a new function that is function of g(x).

The final function is

$f(x)=0.5\cdot g(x-2)+1$

We start by calculating g(x-2):

$g(x-2)=(x-2)^3-(x-2)\\\\g(x-2)=(x^3-6x^2+12x-8)-(x-2)\\\\g(x-2)=x^3-6x^2+11x-6$

Then, we can calculate f(x) as:

$f(x)=0.5\cdot g(x-2)+1\\\\g(x-2)=x^3-6x^2+11x-6\\\\\\f(x)=0.5(x^3-6x^2+11x-6)+1\\\\f(x)=0.5x^3-3x^2+5.5x-3+1\\\\\\f(x)=0.5x^3-3x^2+5.5x-2$

Which of the following describes the translation of the graph of y = x 2 to

VLD [36.1K]

Answer:

reflect over the x-axis and shift down 3

Step-by-step explanation:

The leading coefficient of -1 means the graph is reflected over the x-axis. The addition of -3 to the function means each graphed point is shifted down 3 units from the original.

The graph of y = -x^2 -3 is the result of the transformation ...

What is the slope of <br> y = -x+7

hichkok12 [17]

Answer: -1

Step-by-step explanation:

The equation is given in slope-intercept form. Slope-intercept form is y=mx+b, where m is slope, and b is y-intercept. Since m is slope, we know that it is -1.
