Answer:

The answer to your question is: V = 5x² + 40x + 80

Step-by-step explanation:

Formula = V = r²h

r = x + 4

h = 5

Substitution

V = (x + 4 )² 5                      

V = (x² + 8x + 16)5               expand

V= 5x² + 40x + 80                simplify

If a polynomial has one root in the form a-V6, it has a second root in the<br> form of a _Vb.
e-lub [12.9K]

Answer:

radical form, they occur as two conjugates.

That is,

The conjugate of (a + √b) is (a - √b) and vice versa.

To show that the given conjugates come from a polynomial, we should create the polynomial from the given factors.

Line m includes the points (-3, 3) and (-4,-6). Line n has the same slope as line m and
Sveta_85 [38]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

The slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

We have that the line m passes through the following points:

(x_ {1}, y_ {1}): (-3,3)\\(x_ {2}, y_ {2}): (-4, -6)

So, the slope of the line m is:

m = \frac {-6-3} {- 4 - (- 3)} = \frac {-9} {- 4 + 3} = \frac {-9} {- 1} = 9

Line n has the same slope so the equation is of the form:

y = 9x + b

We have as data that the y-intercept is -\frac{2} {3}. Thus, we have that the equation of line n is:

y = 9x- \frac {2} {3}

ANswer:

y = 9x-\frac {2} {3}

Simora [160]

Answer:

f(3)= -9, g(2)=4

Step-by-step explanation:

F(3)= -2(3) -3

F(3)= -6 -3

F(3)= -9

G(2)= 2^2

G(2)= 2×2

G(2)= 4
