In triangle do pythogrean to find height 5 sq -3sq = 16 and sq rt of 16 is 4
So triangles are 1/2 bh 1/2 (3)4 = 6
One sale 5x5 one shape 5x4 one gape 3x5 plus two triangles
25+ 20+ 15 + 6+6= 72
Answer: y = 0.833333333333x + 3.16666666667
Step-by-step explanation: i think i might have did it wrong not completly sure
The data is equally spaced in x so let's start by taking first differences.
4-9 = -5
-1-4 = -5
-6 - -1 = -5
-11 - -6 = -5
Hmmm. I detect a pattern. That tells us we have a line and the slope is -5.
We read off the y intercept from x=0 as -1.
So our equation in slope intercept form is
y = -5 x - 1
or as a function
(1mile/57.1 sec) x (3,600 sec/hour) = 1 x 3600/57.1 = 63.05 mile/hour<span> (rounded)</span>
