Answer:
Part A: 2,100 cm²
Part B: 5,880 cm³
Step-by-step explanation:
Area 1st rectangle = 15*28
Area 2nd rectangle = 20*28
Area 3d rectangle = 12*28
Area 4th rectangle = 13*28
Area trapezoid =(1/2) ( base1 + base2)*height = (1/2) (15+20)*12
There are two such trapezoids.
Complete surface area = 15*28 + 20*28 +12*28+13*28 + 2 *(1/2)(15+20)*12 =
= 2,100 cm²
Part B.
Volume = base area*height prism
Base area = area trapezoid = (1/2) (base1 a+ base2)*heght trapezoid =
= (1/2)*(20+15)*12
Volume = (1/2)*(20+15)*12*28 = 5,880
Appears that you've overlooked the need to share the possible answer choices.
f(x)=x^2x-1 has a parabolic graph with vertex at (0,-1). This is also the location of the vertex. Because the coefficient of x^2 is positive, this graph opens up. Thus, the smallest possible y value here is -1. The range of this function is
[-1, infinity).
No because a 2 digit divisor always has less digits than a 3 digit divisor
