Answer:
Temperature after 12 hours = 25°C
Step-by-step explanation:
Given:
Current tempreture = -23°C
Tempreture incresing rate = 4°C per hour
Total time = 12 hour
Find:
Temperature after 12 hours
Computation:
Temperature after 12 hours = Current tempreture + (Tempreture incresing rate)(Total time)
Temperature after 12 hours = -23 + (4)(12)
Temperature after 12 hours = -23 + 48
Temperature after 12 hours = 25°C
Answer:
B. -2
Step-by-step explanation:
All you have to do is look at 2 on the x axis and see where it lines up on the graph with the y axis. In this case, when you trace the line of 2 it matches up with -2 on the graph.
Answer:
y=1/2+1
Step-by-step explanation:
1) Y2-Y1 over X2-X1
<u>9-5=4</u>
12-4=8
4/8 simplify the answer= 1/2
m=1/2
2) subtitute the simplification to one of the points.
y=mx+b
5=1(4)+b
5=4=b
1=b
y=1/2+1
339.12 m^3 because you use the formula for the volume of a sphere
