Answer:
V = -0.5
Step-by-step explanation:
V is equal to:
2 + (-5 * 0.5)
2 + -2.5
-0.5
B. 2.9 m, 3.0 m, 3.1 m, 3.2 m
3x-5=7
3x=7+5
3x=12
X=12/3
X=4
The average rate of change on [1, 3] is calculated as: [h(3) - h(1)] / 2
For the first set of (x, y) values: h(3) = 6, h(1) = -2, so [6 - (-2)] / 2 = 4.
For the graph, h(3) = 4, h(1) = -2, so [4 - (-2)] / 2 = 3, which is what we need.
For the equation, h(3) = 27/8 - 1 = 19/8, while h(1) = 1/2, so (19/8 - 1/2) / 2 = 15/16.
Therefore only the second choice, the graph, fits the required.
Answer:
31
Step-by-step explanation:
In circle S: XB and XD are tangents at B and D
then SB perpendicular to AX and SD perpendicular to XC
In triangle SDX: SD = 12 and SX =20 by using Pythagoras Theorem
XD = XB tangents to circle S from point X
XA = XC tangents to circle R from point X
then BA = DC = 15
then XC = XD + DC = 16 + 15 = 31
