The original function is
f(x)=√x
As this is condition for √x function, x≥ 0
So,
Domain= [0, infinity)
Range= [0, infinity)
After the reflection across x-axis and y-axis, we get a function,
g(x)=-√-x
-x≥ 0 means x≤ 0,
So,
Domain= (-infinity, 0]
Range= (-infinity, 0]
From this you can see that
-The only value that is in the domains of both functions is 0.
-The range of g(x) is all values less than or equal to 0.
only these points are correct and all other points are wrong.
See the attached graphs for both functions.
Answer:
Step-by-step explanation:
Slope is the change in y values divided by the change in x values
m = (y₂ - y₁) / (x₂ - x₁)
1) (2 - 1) / (-17 - -3) = -1/14
2) (-10 - -4) / (-12 - -20) = -6/8 = -3/4
3) (-8 - -5) / (0 - -12) = -3/12 = -1/4
4) (14 - 10) / (-7 - 8) = -4/15
The long leg and the hypotenuse of the isosceles right triangle will be 7.07 units.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The short leg of a 90-45-45 triangle is 5.
The right triangle is an isosceles right triangle. Then the two side will be same.
Then the long leg and the hypotenuse will be
H² = 5² + 5²
H² = 25 + 25
H² = 50
H = 7.07 units

Answer:
53.1°
Step-by-step explanation:
Let x represent the wangle of elevation from B to C
Reference angle = x
Opposite side to x = 16 - 4 = 12
Adjacent = 9
Apply trigonometric ratio to find x.
Thus:
(nearest tenth)
Angle of elevation from B to C = 53.1°
