Hello!
Reading these types of graphs can be difficult, but it displays the following numbers:
27, 30, 31, 43, 45, 49, 51, 58, 62, 64
To find mean, or average, you need to add up all of the numbers and divide by how many there are (10)
This will give you 46.
I hope this helps you and good luck!
Answer:
Line DF, line n, line d
Step-by-step explanation:
(3t² +t -12t - 4)(t+2)=0
(3t³ - 5t² -26t -8) =0
t = -2
H(10) is the altitude of a hot air balloon overtime after 10 minutes. In order to find h(10)'s value, you just have to substitute 10 as t in the equation. h(10) and h(t) represents the value of y in a linear equation. So pretty much: h(10)= 210 - 15(10). If calculated correctly, h(10)=60.
