Answer do we just answer the question or we also have to do something else?
Step-by-step explanation:
Answer:
12.7 feet
Step-by-step explanation:
To solve this question, we use the trigonometric function of Sine
sin θ = Opposite side/Hypotenuse
θ = 42°
Hypotenuse = 19 foot ladder
Opposite side = Distance of the cat from the ground(height of the tree)= unknown
sin 42° = Opposite/19 feet
Opposite = sin 42° × 19
Opposite = 12.713481521 feet
Approximately to the nearest tenth of a foot = 12.7 feet.
Therefore, the cat was 12.7 feet above the ground.
B is the right answer
f(x) = x-3
y= x-3
x= y-3
x+3 =y
f^-1(x) = x+3
Answer:
x=24
Step-by-step explanation:
4(2/3x+2)=3x
8/3x+8=3x
collect like terms
8=3x-8/3x
8=
cross multiplication
9x-8x=8 x 3
x=24
A) x+0.25>-8
-0.25 -0.25
x>7.75
B) -1<x-10
+10 +10
9<x
