Finding gradient:
m = y2 - y1
x2 - x1
= -1 - 6
1 - 3
= -7 / (-2)
= 7/2
y = m(x - x1) + y1
y = 7(x - 3) + 6
2
2y = 7x - 21 + 12
2y = 7x - 9
Answer:
B
Step-by-step explanation:
-8+2=-6 and im pretty sure negative of a power is just a regular power so its B
5,3..........................................
3/5 is bigger because 4/7 = 20/35 and 3/5 = 21/35
Answer: 12,8 approximately 13 cones
Step-by-step explanation:
1] volume of a cone
V=1/3πr^2h
V=1/3π(3)^2(5)
V=47,12 cubic inches
2] volume of a cylinder
V=πr^2h
V=π(8)^2(3)
V=603.19
Now devide the volume of a cylinder by the volume of a cone
603,19÷47,12=12,8 cones
