Answer:
The y-coordinate is changing by the rate of -70 cm per sec.
Step-by-step explanation:
Given equation,
Differentiating with respect to time (t),
We have,
Answer:
C
Step-by-step explanation:
y = (2x - 2) / 4 Interchange x and y
x = (2y - 2) / 4 Multiply both sides by 4
4x = 2y - 2 Add 2 to both sides.
4x + 2 = 2y Divide both sides by 2
4x/2 + 2/2 = 2y / 2
2x + 1 = y
Now put 3 in wherever you see an x
2*3 + 1 = y
6 + 1 = y
7 = y
Answer: D
Explain: The one described was B, but the one that changes LESS is D
Answer: 42/11 = 21/5.5
Step-by-step explanation:
1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.
2) Therefore, the ratio is 42/11.
3)The adjacent sides to the right angle are 21 and 5.5.
4)Therefore, the ratio is 21/5.5
No. 1/12 is a smaller amount than 1/3.
