Answer:
x positive, y negative
Step-by-step explanation:
-60 is the 4th quadrant of the unit circle ( negative angles go clockwise from 0), so the x value is positive and the y value is negative.
Answer:
y = 9.75
Step-by-step explanation:
Since both triangles are said to be similar, the proportion or ratio of the sides of both triangles would be equal.
Therefore, 39/y = 23/5.75 = 35/8.75
Let's find y
39/y = 23/5.75
==>Cross multiply
39*5.75 = 23*y
224.25 = 23y
==>Divide both sides by 23
224.25/23 = y
9.75 = y
y = 9.75
Check:
Thus,
39/9.75 = 23/5.75 = 35/8.75 = 4
Our answer y, which is 9.75, is correct.
Answer:
15
Step-by-step explanation:
15 cubed (15×15×15) equals 3375
Answer:
12
Step-by-step explanation:
y = kx
2⅔ = k(¼)
8/3 = k/4
k = 4×8/3 = 32/3
y = (32/3)x
y = (32/3)(1⅛)
y = (32/3)(9/8)
y = 3×4 = 12
