Answer
58
Step-by-step explanation:
So you would plug in 4 for h and 6 for g to get 4+9(6), then you multiply 9x6 to get 54 then you would add 4 to get 58
Answer:
i would say B/90
Step-by-step explanation:
Answer:
y= -1x + 2
Step-by-step explanation:
-4/4 is the same as saying -1. slope always has to be in the simplest form.
X is 90 degrees. If AB is the diameter, then it passes through the centre. X is 90 degrees because the angle in a semicircle is always a right angle.
Answer:
12 cm
Step-by-step explanation:
To calculate the length of a spring with a 2 kg load, compare the displacement of a 1 kg load and adjust accordingly.
When a 1 kg load is suspended from the spring, the spring which is 6 cm stretches to 9 cm. This is 3 cm longer due to the weight. If you attach a weight which is twice as much then the displacement will be twice as much. Instead of stretching an additional 3 cm, it will stretch 2*3 = 6 cm. Add this to the length of the spring and it stretches in total 6 + 6 = 12 cm.
