Answer:y=16
Step-by-step explanation:
Answer:
y + 4 = 2(x+1)
Step-by-step explanation:
Begin by calculating the slope m using the slope formula. Then substitute m and (-1,-4) into the point slope form. The point slope form of the line is .
Slope Formula:
Substitute m = 2 and (-1,-4).
Let
P1 = (x1, y1) = (4, 7)
P2 = (x2, y2) = (2, 3)
The first thing to do in this case is to find the distance between two points by the following equation:
d (P1, P2) = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
d (P1, P2) = root ((2-4) ^ 2 + (3-7) ^ 2) = 4.47
answer
The houses are separated 4.47 units.
Answer:
Original position: base is 1.5 meters away from the wall and the vertical distance from the top end to the ground let it be y and length of the ladder be L.
Step-by-step explanation:
By pythagorean theorem, L^2=y^2+(1.5)^2=y^2+2.25 Eq1.
Final position: base is 2 meters away, and the vertical distance from top end to the ground is y - 0.25 because it falls down the wall 0.25 meters and length of the ladder is also L.
By pythagorean theorem, L^2=(y -0.25)^2+(2)^2=y^2–0.5y+ 0.0625+4=y^2–0.5y+4.0625 Eq 2.
Equating both Eq 1 and Eq 2: y^2+2.25=y^2–0.5y+4.0625
y^2-y^2+0.5y+2.25–4.0625=0
0.5y- 1.8125=0
0.5y=1.8125
y=1.8125/0.5= 3.625
Using Eq 1: L^2=(3.625)^2+2.25=15.390625, L=(15.390625)^1/2= 3.92 meters length of ladder
Using Eq 2: L^2=(3.625)^2–0.5(3.625)+4.0625
L^2=13.140625–0.90625+4.0615=15.390625
L= (15.390625)^1/2= 3.92 meters length of ladder
