A "regular quadrilateral" is a square, so the length and width are both 4 cm. The surface area of a rectangular prism is given by
S = 2(LW +H(L +W))
S = 2((4 cm)*(4 cm) +(6 cm)*(4 cm +4 cm))
S = 2(16 cm² +48 cm²)
S = 2*64 cm² = 128 cm²

The surface area of the prism is 128 cm².

Whats (8,2) and (9,3) in finding the slope from points

igor_vitrenko [27]

A (8, 2)
B (9, 3)
$m = \frac{yb - ya}{xb - xa}$
$m = \frac{3 - 2}{9 - 8}$
$m = \frac{1}{1}$
$m = 1$

What is the difference between the exact simple interest and the ordinary simple interest on a 200-day loan of 5,000 at 12%

77julia77 [94]

Answer:

4.56

Step-by-step explanation:

"Ordinary" interest will be more than "exact" interest because the number of days in a year is a smaller value. The difference will be ...

Io = Prt = 5000(0.12)(200/360) = 333.33

Ie = Prt = 5000(0.12)(200/365) = 328.77

The difference is ...

333.33 -328.77 = 4.56 . . . the difference in interest values

_____

<em>Additional comment</em>

The question asks for the difference between exact and ordinary interest, so the result is technically negative:

328.77 -333.33 = -4.56
