we need to find d=equation, so:
−8+6=−10+10
-8d=-10k+10-6
-8d=-10k+4
d=(-10k+4)/(-8)

So the answer is:
d=(5/4)k-1/2
or
d=1.25k-0.5
Answer:
22 m
Step-by-step explanation:
Total distance travelled by marble while falling down = height above surface of lake + depth of lake = 15 + 7 = 22 m
Answer:
136 m2 Option c
Step-by-step explanation:
136 m2
1 base = 6 × 7 = 42
2 sides = 2(7 × 5) = 70
2 triangles = 2(6 × 4
2
) = 24
SA = 42 + 70 + 24 = 136 m2
