Range → (3, ∞) Or y > 3
Step-by-step explanation:
f(x) = (0.25)ˣ + 3
By using graphing tool find the graph of the given function.
Given exponential function is defined for all x-values and domain is a set of x-values (input values) of the function.
Domain of the function → (-∞, ∞) Or set of all real numbers
Range of a function is a set of y-values (output values)
Range of the given function → (3, ∞) Or y > 3

consider the function f(x)=6sin(x-pi/8)+8. What transformation results in g(x)=6sin(x-7pi/16)+1?
Answers
Answer: we have a vertical shift of 7 units down, and a horizontal shift of 5*pi/16 units to the right.
Step-by-step explanation:
First, let's define the transformations:
Vertical shift.
If we have a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
This will move the graph of f(x) up or down a distance of N units.
if N is positive, then the shift is upwards
if N is negative, then the shift is downwards.
Horizontal shift.
If we have a function f(x), a horizontal shift of N units is written as:
g(x) = f(x + N)
This will move the graph of f(x) to the right or left a distance of N units.
if N is positive, then the shift is to the left
if N is negative, then the shift is to the right.
Here we have:
f(x) = 6*sin(x - pi/8) + 8
and the transformed function:
g(x) = 6*sin(x - (7/16)*pi) + 1
We can assume that the transformations are a vertical shift of A units, and an horizontal shift of B units, then we can write:
g(x) = f(x + B) + A
g(x) = 6*sin(x + B - pi/8) + (8 + A) = 6*sin(x - (7/16)*pi) + 1
Then we must have that:
(x + B - pi/8) = x - (7/16)*pi
B - pi/8 = -(7/16)*pi
B = -(7/16)*pi + pi/8 = -(7/16)*pi +2*pi/16 = (-7 + 2)*pi/16 = -5*pi/16
And we also must have that:
8 + A = 1
A = 1 - 8 = -7
Then the transformation is:
g(x) = f(x - 5*pi/16) - 7
This means that we have a vertical shift of 7 units down, and a horizontal shift of 5*pi/16 units to the right.

Answer:
B
Step-by-step explanation:
The given equation is in slope-intercept form:
y = mx + b
where the slope is m = -3 and the y-intercept is b = +2.
So, the graph will have a slope of ...
"rise"/"run" = -3 = -3/1
and will cross the y-axis at y=2.
Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.
Here is a rectangle ABCD.
20 cm
30 cm
The length of the rectangle is increased by 20%.
The width of the rectangle is increased by 10%.
Find the percentage increase in the area of the rectangle.
12
Answers
Answer:
32%
Step-by-step explanation:
Area of rectangle ABCD = 20 * 30 = 600 Sq cm
After increasing the length and width of the rectangle by 20% and 10% respectively.
New length = 30 + 20% of 30 = 30 + 6 = 36 cm
New width = 20 + 10% of 20 = 20 + 2 = 22 cm
Area of new rectangle = 36*22 = 792 Sq cm
Increase in area = 792 - 600 = 192 Sq cm
Percentage increase in area
= (192/600) *100
= 32%

C 15km
D 21km
Answers
Answer:

The airplane must travel [tex]\sqrt{315}[/tex] km to be directly above the airport.
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
We have to apply the Pythagoras theorem to solve the problem.
By Pythagoras theorem,
Base² + Altitude² = Hypotenuse²
Given,
Altitude = 3 km
Hypotenuse is the slant distance from the airport = 18 km
Let x be the distance plane must travel to be directly above the airport.
x² + 3² = 18²
x² = 315
x = [tex]\sqrt{315}[/tex]
Hence the distance plane must travel is [tex]\sqrt{315}[/tex] km.

Answers
Answer:
[tex]y=3x-8[/tex]
Step-by-step explanation:
First, you have to isolate y on one side of the equation.
Step 1) Add 5 to both sides (this will cancel out the (-5) on the left)
Step 2) Subtract 3x from both sides (this will cancel out the (3x) on the left)
Step 3) Subtract y from both sides
Step 4) In order to make the desired variable positive, change the sign of everything in the equation
The step shown above will yield the answer of [tex]y=3x-8[/tex]
