Answer:
it is decreasing in the time interval 0<x<2 hours.
Step-by-step explanation:
Graph of first line going through ordered pairs A(0, 40) and B(2, 10).
Graph of second line going through ordered pairs B(2, 10) and C(4, 10). Graph of third line going through ordered pairs C(4, 10) and D(7, 50).
When movement is from point A to B, change in x = 2 and change in y = -30
Hence change for unit x = -30/2 = -15 ... i
When movement is from point B to C, change in x = 2 and change in y = 0
Hence change for unit x = 0/2 = 0 ... ii
When movement is from point C to D, change in x = 3 and change in y = +40
Hence change for unit x = 40/7 = 5.71 .. iii
Hence from A to B it is decreasing, B to C it remains constant and C to D it is increasing.
x coordinate represents hours and y coordinate degrees.
Hence answer is it is decreasing in the time interval 0<x<2 hours.
Answer:34.4
Step-by-step explanation:
172.5-137.1=34.4
As a general rule to solve the problem we are going to transform all values to the lower unit.
a. 3 km 9 hm 9 dam 19 m + 7 km 7 dam
3,000 m 900 m 90 m 19 m + 7,000 m 70 m = 4,009 + 7,070 = 11,079 m
b. 5 sq.km 95 ha 8,994 sq.m + 11 sq. km. 11 ha 9,010 sq. m.
5,000,000 sq m 95,0000 sq m 8,994 sq m + 11,000,000 sq m 110,000 sq
9,010 sq m
5,103,994 sq m + 11,119,010 sq m = 16,223,004 sq m
c. 44 m – 5 dm
44 m - 0.5 m = 43.5 m
d. 73 km 47 hm 2 dam - 11 km 55 hm
73,000 m 4,700 m 20 m - 11,000 m 5,500 m
77,720 m - 16,500 m = 61,220 m
Answer:
0 dollars
=E(M)
=μ
M
=−$10,000(0.81)+$40,000(0.18)+$90,000(0.01)
=−8,100+7,200+900
=0
<u>ANSWER</u>
<u>EXPLANATION</u>
The given compound inequality is
We need to simplify this inequality so that we can obtain x standing alone between the inequality signs.
We add 6 through out the inequality.
This simplifies to:
We now divide through by -3 and reverse the inequality sign.
We now simplify to get:
