Answer:
u is (0,2.3) v is (-2,1.1) w is( -4,-1) x is (2.5,0) Y is (2,-1.5) Z (-1.5,-3)
Step-by-step explanation:
you start with the x axes then follow with the y
Your answer for this question would be y= 3/2x+7
Answer:
10 feet
Step-by-step explanation:
Given that the distance to be reached is 8 feet above ground and she she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house, the length of the ladder considered with the other lengths forms a right angled triangle.
The length of the ladder represents the hypotenuse side hence using pythagoras theorem
F^2 = 8^2 + 6^2
where F is the length of the ladder in feet
F^2 = 64 + 36
= 100
find the root of both sides
F = 10 feet
The ladder is 10 feet long
Answer:
x² -25
Step-by-step explanation:
(x +5)(x -5) = x(x -5) +5(x -5) = x² -5x +5x -25 . . . . . 5x terms cancel
= x² -25
_____
This is an example of the factoring of the difference of squares:
(a+b)(a-b) = a²-b²
Answer:
12.5 in^2
Step-by-step explanation:
25=2(3.14)r
25=6.28r
Divide by 6.28 on both sides:
3.98089172=r
Now use 
:
12.5 in^2
