Answer:
6
Step-by-step explanation:
Answer:
height of the wall = 9.79 m
Step-by-step explanation:
This form a right angled triangle.
Hypotenuse = length of the ladder = 10 m
Base = length from foot of ladder to wall.
Altitude = height of the wall
Pythagorean's theorem,
base² + altitude² = hypotenuse²
2² + altitude² = 10²
4 + altitude² = 100
altitude² = 100 - 4
altitude² = 96
altitude = √96 = 9.79 m
Answer:
Step-by-step explanation:
perp. -1/3
y - 2 = -1/3(x + 9)
y - 2 = -1/3x - 3
y = -1/3x - 1
answer is C
Answer:
(0, 3 )
Step-by-step explanation:
To find the y- intercept , substitute x = 0 into f(x), that is
f(0) = 3 ×
[ note
= 1 ]
= 3 × 1
= 3
y- intercept = (0, 3 )
