The degree is equal to 6!
Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Answer:
2nd option
Step-by-step explanation:
using the converse of Pyhagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 100 , then 100² = 10000
60² + 80² = 3600 + 6400 = 10000
then
60² + 80² = 100²
thus the triangle is right
Radius = Diameter ÷ 2 = 10 ÷ 2 = 5mm
<u>
Find Volume: </u>
Volume= πr²h
Volume = π (5)² (6) = 471.24mm³ (Nearest hundredth)
<u>Find Surface Area:</u>
Surface area = 2πr² + 2πrh
Surface area = 2π(5)² + 2π(5)(6) = 345.58 mm²
Answer: Volume = 471.24mm³ , Surface area = 345.58 mm²
