X intercepts: (37/8,0)
y intercepts: (0,37/9)
51) 5x-1=0 and x+6=0
5x=1, x=1/5 and x=-6
2 solutions x=1/5 and x=-6
52)x(2x+3)=0
2x=0 and 2x+3 =0
x=0 and x=-3/2=-1.5
53) x(5x-1)=0
x=0 and 5x-1=0
x=0 and x=1/5
54) z(4z+7) =0
z=0 and 4z+7=0
z=0 and z= - 7/4 = -1.75
z=0 and z=-1.75
Answer:
94 m
Step-by-step explanation:
Write a proportion:
3.1 / 1.18 = x / 35.75
Cross multiply and solve:
1.18x = 3.1 × 35.75
1.18x = 110.825
x ≈ 94
Rounded to the nearest meter, the height of the tower is approximately 94 meters.
35 cm
using the formula a=1/2(b)(h), we can plug in 14 for b and 5 for h. This gives us 70, and when we multiply by 1/2 it leaves 35 cm.
Slope = 4/1 = 4
