Answer:
D
Step-by-step explanation:
The opposite faces of the prism are congruent , then
SA = areas of (top/bottom + front/ back + 2 sides )
= 2(19 × 16) + 2(19 × 10) + 2(16 × 10)
= 2(304) + 2(190) + 2(160)
= 608 + 380 + 320
= 1308 m² → D
I'm sorry is this a comment? I need more information, Thank you.
S(x) = x - 7; t(x) = 4x² - x + 3
(t · s)(x) = (4x² - x + 3)(x - 7) = (4x²)(x) + (4x²)(-7) - (x)(x) - (x)(-7) + (3)(x) + (3)(-7)
= 4x³ - 28x² - x² + 7x + 3x - 21 = 4x³ - 29x² + 10x - 21
Replace x with the x values of the choices and see if it solves to equal the y value:
Y=-7x + 2
A) (1,2)
Y = -7(1) + 2 = -7 + 2 = -5 not 2
A is wrong
B (8,-54)
Y = -7(8) + 2 = -56+ 2 = -54
This works out.
The answer is B
The answer should be B because it turns to .15
