Answer: B. 29 mi (which you typed 29 in)
Step-by-step explanation:
Use law of cosine to solve: a²=b²+c²-2bc·cosA (the corresponding angle)
a²=19²+12²-2×19×12×cos (138)
a²=361+144-456cos(138)
a²=505-456cos(138)
a²=843.874 (rounded)
a=29 mi
ANSWER
d. The set of all real numbers
EXPLANATION
The basic cosine function ,
is continuous everywhere.
The function is defined for all real values of x.
The domain is the set all values of x that will make the function defined.
The domain is all real numbers.
The correct choice is D.
If Leigh uses the strategy, the statement that describes the figure is A. 3 full squares and 12 partial squares.
<h3>How to depict the information?</h3>
From the information, Leigh plans to estimate the area of the figure on the grid by identifying the full and partial squares that make up the figure.
It was stated that on a coordinate plane, a figure contains 3 full squares and 12 partial squares.
Therefore, the correct option is A.

For
ax+by=c
slope=-a/b
we have
-6x+1y=-4
slope=-6/-1=6
slope is 6
yint is where x=0
-6(0)+y=-4
0+y=-4
y=-4
yint is at y=-4 or (0,-4)
