Answer:

When x = 2, f(x) = 63.

Step-by-step explanation:

In order to find the value of f(x), you have to substitute x = 2 into the function :

$f(x) = - 3 {x}^{2} + 180x - 285$

$f(2) = - 3{(2)}^{2} + 180(2) - 285$

$f(2) = - 12 + 360 - 285$

$f(2) = 63$

Finding the Equation of a Line from a Graph and a Table <br><br> plz help me

Leni [432]

Answer:

slope (m)= 1/2

y-intercept: (0, -1)

equation: y= $\frac{1}{2}$ x-1

Step-by-step explanation:

slope is $\frac{rise}{run\\}$ = $\frac{1}{2}$

y-intercept is where the line crosses the vertical axis (y-axis) so its (0, -1)

using point slope form:

y-y1=m(x-x1)

y-(-1)=1/2(x-0)

y+1=1/2x

y= $\frac{1}{2}$ x-1

What are the zeros of f(x) = x3 + 6x2 + 3x – 10 ?

schepotkina [342]

One of the zeroes would be : x = 1

f (1) = 1^3 + 6(1) ^2 + 3 (1) - 10

f(1) = 1 + 6 + 3 - 10

f (1) = 10 - 10

f (1) = 0

Hope this helps

Evaluate exactly in radians: arctan(1/sqrt(3)). Show solution w/ explanation.

balandron [24]

Arc tan ( 1/√3 ) = arc tan ( √3/3 ) = 30°
180° = π ( in radians )
30° = 180°/6 = π/6
