Step-by-step explanation:

The area A of the tire in contact is 7"×5" = 35 sq inches and we know that each tire has a pressure of 30 psi so the weight of the car in tons is

$W = \dfrac{APN}{2000} = \dfrac{(35\:\text{in}^2)(30\:\text{lbs/in}^2)(4)}{2000}$

$\:\:\:\:\:= 2.1\:\text{tons}$

A. (f + g)(x)
3x + 7 + 4x - 2
7x + 5 <====

B. (f * g)(x)
(3x + 7)(4x - 2) =
3x(4x - 2) + 7(4x - 2) =
12x^2 - 6x + 28x - 14
12x^2 + 22x - 14 <===

C. f[g(x)]
3(4x - 2) + 7 =
12x - 6 + 7 =

What is the surface area of a square pyramid with a slant height of 6cm and the length of one side of the square base is 5cm

erica [24]

Answer:

S = 85cm^2

Step-by-step explanation:

The surface area of a square pyramid is given by the following formula:

$S=2hb+b^2$

where it has taken into account the sum of the area of a square and four triangles:

$4(\frac{hb}{2})+b*b=2bh+b^2$

h: slant height = 6cm

b: base = 5cm

By replacing in the formula you obtain:

$S=2(5cm)(6cm)+(5cm)^2=85cm^2$

hence, the surface area is 85cm^2
