Answer:
"D"
Step-by-step explanation:
just add the two functions
5x^2 - 8x^2 = -3x^2 etc
I think a and c. I really don’t know tho
Answer:
wait what are we measuring I would need to see the graph to know
Answer:
The answer is C, 296. 73
Step-by-step explanation:
Top Surface Area = π×4.52
= 63.617251235193 inches2
Bottom Surface Area = π×4.52
= 63.617251235193 inches2
Lateral Surface Area = 2π×4.5×6
= 169.64600329385 inches2
Total Surface Area = 296.88050576424 inches2
Answer:
45.6° (1 d.p)
Step-by-step explanation:
Using the cosine rule;
c = √( a² + b² - 2ab Cosx)
11 =√(8² + 15² - 2 (8) (15) Cosx)
11² = 8² + 15² - 240 Cosx
11² - 8² - 15² = - 240 Cosx
-168 = -240 cosx
cosx = 0.7
x = cos⁻¹ (0.7) = 45.57 ≈ 45.6°
