F(x)=x^2+3x-5. find and simplify f(x+h)-f(x)

jarptica [38.1K]

Answer:

$f(x + h) - f(x) = h^2 + 3h - 5$

Step-by-step explanation:

Given

$f(x) = x^2 + 3x - 5$

Required

Find f(x + h) - f(x)

In functions:

$f(x + h) = f(x) + f(h)$

So:

$f(x + h) - f(x) = f(x) + f(h) - f(x)$

Collect Like Terms

$f(x + h) - f(x) = f(x) - f(x)+ f(h)$

$f(x + h) - f(x) = f(h)$

Solving for f(h)

$f(h) = h^2 + 3h - 5$

So:

$f(x + h) - f(x) = h^2 + 3h - 5$

Answer:

see explanation

Step-by-step explanation:

The directed lines have the form < x, y >

With the usual notation

right in x- direction → +

left in x- direction → -

up in y- direction → +

down in y- direction → -

21

EF = < 4, 1 >

22

FG = < 4, - 2 >

23

GH = < - 4, - 2 >

24

EH = < 4, - 3 >

I keep putting in the formula but I keep getting the answer wrong

Advocard [28]

Answer:

314 in² (nearest whole number)

Step-by-step explanation:

Radius of a regular polygon: The distance from the center of the polygon to any vertex. The radius of a hexagon is equal to the length of one side.

Therefore, from inspection of the given diagram:

radius = 11 in ⇒ side length = 11 in

To find the area of a regular polygon, we first need to calculate the apothem. The apothem is the line drawn from the center of the polygon to the midpoint of one of its sides.

$\textsf{Length of apothem (a)}=\dfrac{s}{2 \tan\left(\frac{180^{\circ}}{n}\right)}$

where:

s = length of one side
n = number of sides

Given:

s = 11 in
n = 6

Substitute the given values into the formula and solve for a:

$\implies \textsf{a}=\dfrac{11}{2 \tan\left(\frac{180^{\circ}}{6}\right)}=\dfrac{11\sqrt{3}}{2}$

Area of a Regular Polygon

$\textsf{A}=\dfrac{n\:s\:a}{2}$

where:

n = number of sides
s = length of one side
a = apothem

Given:

n = 6
s = 11

$\textsf{a}=\dfrac{11\sqrt{3}}{2}$

Substitute the given values into the formula and solve for A:

$\implies \sf A=\dfrac{6 \cdot 11 \cdot \dfrac{11\sqrt{3}}{2}}{2}$

$\implies \sf A=314.3672216...$

$\implies \sf A=314\:\:in^2\:\:(nearest\:whole\:number)$
