Answer:
1/3
Step-by-step explanation:
Slope intercept form: y=mx+b
m=rise/run (slope)
b= y-intercept
b=1/3
1. Since we have <span>two sides (AC and AB) and the included angle (60°), we are going to use the law of cosines to find the length of BC:
</span>
<span>
We can conclude that the length of the side BC is </span>
.
2. To find the area of triangle ABC we are going to use Heron's formula:
where
is the area of the triangle
is the semi-perimeter of the triangle
But first, we are going to find the semi-perimeter of our triangle using the formula:
We can infer for our triangle and from our previous calculation that
,
, and
. Lets replace those values to find the semi-perimeter of our triangle:
Finally, we can use Heron's formula to find the area of our triangle:
We can conclude that the area of our triangle is
10.42 square units.
5y - 6 = 18. Add 6 to both sides. 5y = 24. Divide by five and you end up with y = 24/5, which could also be written as 4.8.
Answer:
a) g(-2) = -2
b) g(1) = 1
c) g(x) = 1 then x = 1 or -1
d) D: {all reals}
R: {y ≤ 2}
