Use the law of cosines to find the balue of cos 0 . Round to answer to two decimal places

chubhunter [2.5K]

Answer:

Step-by-step explanation:

Using the law of cosines then cosΘ is the following quotient

cosΘ = $\frac{a^2+b^2-c^2}{2ab}$

where a = 5.8, b = 10.5 and c = 10.9

cosΘ = $\frac{5.8^2+10.5^2-10.9^2}{2(5.8)(10.5)}$

= $\frac{33.64+110.25-118.81}{121.8}$

= $\frac{25.08}{121.8}$ = 0.21 → C

C.) y is greater than or equal to -6

Step-by-step explanation:

The range are all the set of y-values that are plotted on the vertical axis (y-axis).

The range starts from -6 and above. Which is y ≥ -6

Therefore, range of the function is said to be:

A supplier sells 2 and 1/4 pounds of mulch for every 1 and 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and grav

polet [3.4K]

Because ratios can be written as fractions
$\frac{mulch}{2.25}=\frac{gravel}{1.33}$

172 = $\frac{mulch}{2.25}+ \frac{gravel}{1.33}$
172 - $\frac{mulch}{2.25}$ = $\frac{gravel}{1.33}$
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56
