Answer:
Step-by-step explanation:
because <u>c</u> is shorter than<u> a</u> we know C is a smaller angle than A
so the first choice is out.
use the law of cosines to find b
= 
=1681+400-1326.787871
= 754.21219
b= 
b= 27.46292
so the last choice looks good
Mixing the two ingredients would be adding them together:
1/2 gram + 3/4 gram = 1 1/4 total grams
Divide the total grams by 1/8 to find the number of experiments they can do:
1 1/4 / 1/8 = 5/4 / 1/8 = 5/4 * 8/1 = 40/4 = 10
They can conduct 10 experiments.
keeping in mind that a year has 12 months, thus 6 months is really 6/12 of a year.

It means the scatter plot is a line with negative slope. The relation is perfectly described by a linear equation.
Answer: 0.4^3
