A. Factor the polynomial: x^5-4x^3+8x^2-32<br> b. Solve by factoring: 2x^2-3x+1=0
lawyer [7]

Answer:

a. (x^3+8)(x^2-4)

b. x=1 and x=1/2

Step-by-step explanation:

a. (x^3+8)(x^2-4) = x^5-4x^3+8x^2-32 [foil method: first,outside,inside,last]

b. use quadratic formula: -b +/- square root b^2-4ac / 2a

2=a; -3=b; 1=c

-(-3) + square root (-3)^2 - 4(2)(1) / 2(2)

3 + 1 / 4 = 4/4 = 1

3 - 1/4 = 2/4 = 1/2

Solve the problem. Find the surface area of a right regular hexagonal pyramid with sides 2 cm and slant height 5 cm. Round youra
BabaBlast [244]

Answer:

The surface area of the right regular hexagonal pyramid is 50.78 cm².

Step-by-step explanation:

Given:

A right regular hexagonal pyramid with sides(s) 2 cm and slant height(h) 5 cm.

Now, to find the surface area(SA) of the right regular hexagonal pyramid.

So, we find the area of the base(b) first:

Area of the base = \sqrt[3]{3}\times s^{2}

                            = \sqrt[3]{3}\times 2^{2}

On solving we get:

Area of the base(b) = 20.784

Then, we find the perimeter(p) :

Perimeter = s × 6

p=2\times 6=12

Now, putting the formula for getting the surface area:

Surface area = perimeter × height/2 + Area of the base.

SA=\frac{p\times h}{2}+b

SA=\frac{12\times 5}{2}+20.784

SA=30+20.784

SA=50.784

As, <em>the surface area is 50.784 and rounding to nearest hundredth becomes 50.78 because in hundredth place it is 8 and in thousandth place it is 4 so rounding to it become 50.78.</em>

Therefore, the surface area of the right regular hexagonal pyramid is 50.78 cm².
