Given:

26 meter-long wire cut into two pieces

let x = perimeter of square
26 -x = perimeter of circle

Use the formulas for the perimeters and areas of the two shapes:

P sq = x = 4s
P ci = 26 - x = 2 * pi * r

A sq = s^2
A ci = pi * r^2

Manipulate the equations to come up with a maximum and minimum function. Equate the function to zero and solve for x, then find the area.

The probabilities can be calculated using an online calculator or tables, depending on which is more readily available.

QUESTION A

$P(Z>1.48)$

Using calculators, the probability will be:

$P(Z\gt1.48)=0.069$

QUESTION B

$P(Z\leq1.94)$

Using calculators, the probability will be:

$P(Z\leq1.94)=0.974$

QUESTION C

$P(-0.76Using calculators, the probability will be:[tex]P(-0.76\lt Z\lt2.05)=0.756$

The graph represents a cubic function. Write the function.

Norma-Jean [14]

Zeros are

(0,0)
(-3,0)
(-4,0)

Write in factor form and solve

(x-0)(x-(-3))(x-(-4))=0
x(x+3)(x+4)=0
x[x(x+4)+3(x+4)]=0
x(x²+4x+3x+12)=0
x(x²+7x+12)=0
x³+7x²+12x=0

Points given (-2,16)

Solve for n

n(x³+7x²+12x)=y

On solving we get

n=-4

So the function is

y=-4(x³+7x²+12x)
y=-4x³-28x²-48x
