Answer:
54
Step-by-step explanation:
20 ÷ a + 7 • b
Let a = 4 and b = 7
20 ÷ 4 + 7 • 7
Multiply and divide first
5 + 49
Then add
54
G(x)=(x+3)2 we must find x? so x+3=0 x=-3 we transformation -3 on left
Non linear I just put it into Socratic. Because linear functions make straight lines on a graph. This makes a curve, so it is non linear
Step-by-step explanation:
AC = 20
AB = 18
BC² = 20²+ 18² -2•20•18•cos(52°)
BC² = 280.72
BC = √280.72
BC ≈ 16.75
Angle C:
18² = 20² + 16.75² -2•20•16.75•cos(C)
324 = 400 + 280.72 -670•cos(C)
cos(C) = -356.72/-670
cos(C) ≈ 0.53
acos(0.53) = C
C = 57.8°
Angle B:
180-52-57.8 = 70.2°
If you wanted the next larger size you would multiply the known size by the scale factor
to find the smaller size divide the known size by the scale factor:
2.863 / 1.42 = 2.016 ( rounded to the thousandth)
