Answer:
12). LM = 37.1 units
13). c = 4.6 mi
Step-by-step explanation:
12). LM² = 23² + 20² - 2(23)(20)cos(119)°
LM² = 529 + 400 - 920cos(119)°
LM² = 929 - 920cos(119)°
LM =
=
= 37.08
≈ 37.1 units
13). c² = 5.4² + 3.6² - 2(5.4)(3.6)cos(58)°
c² = 29.16 + 12.96 - 38.88cos(58)°
c² = 42.12 - 38.88cos(58)°
c =
c =
c = 4.6386
c ≈ 4.6 mi
Answer:
Figure 2 and 3
Step-by-step explanation:
This question is incomplete, please find the figures in the attachment.
Number of cans of beans bought by Emery = 3
Total weight of cans = 2.4 pounds
weight of each can = = 0.8 pounds
If x be the number of cans and y represents the total weight then the model for this situation will be
y = 0.8x
Figure 1 :
From this graph weight of each can = pounds
so this graph is not the correct choice.
Figure 2:
From this graph weight of each can = = 0.8 pounds
So this graph is the correct choice.
Figure 3 :
From the given table, weight of each can = pounds
So the table shows the relationship.
Figure 4 :
From the given table, weight of each can = = 1.25 pounds
so this table is not the correct choice.
Therefore, figure 2 and 3 is illustrate the relationship.
