To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
3) 7.67 x 10 ^-2
4) 3.3 x 10 ^3
A = 2(9*11) + 1/2(8*11) + 1/2(8 * 9)
A = 198 + 44 + 36
A = 278
Answer
B. 278 in^2
Scenario:
a worker needs to repair a window on the second floor of a building
He is outside 3 feet way from the building
He starts walking and when he reaches the wall he is lifted 4 feet until reaching the window
What is the distance from the window to the point where he has standing before he start walking ?
2))This path forms a right triangle.2 sides are known but not the hypotenuse
Formula a^=b^=c^
a=4 b=3 c=x (Hypotenuse)
3)
Substitute
4^+3^=X^
16+9=x^
25=x^
5=x
Hypotenuse=5
The sides of the triangle formed in this situation are
4,3,and 5
