Answer:
[tex]\displaystyle f^{-1}(6) = -5[/tex]
Step-by-step Explanation:
Recall that by the definition of inverse functions:
[tex]\displaystyle \text{If } f(a) = b\text{, then } f^{-1}(b) = a[/tex]
We are given the function f which contains the point (-5,6). In other words:
[tex]\displaystyle f(-5) = 6[/tex]
Then by the definition of inverse functions:
[tex]\displaystyle f^{-1}(6) = -5[/tex]

Which of the following functions represent exponential decay? f(x)=3(1.7)^x-2
f(x)=3(1.7)^-2x
F(x)=3^5(1/4)^x
F(x)=3^5(2)^-x
Answer:
F(x)=3^5(1/4)^x
Step-by-step explanation:
By the exponential decay definition: y = ab×
b determines the rate at which the graph grows: if b > 1, the function will increase. if 0 < b < 1, the function will decrease.
There is only (1/4)ˣ : where 0<1/4<1 fit the definition, so F(x)=3^5(1/4)^x is the choice
----------------------------------------------------------------------------------------------------------
But.. look at the table attached, the f(x)=3(1.7)^-2x and F(x)=3^5(2)^-x also showed pattern of decay. It can verified from their graphs. (Try plot it with your calculator)

Which of the following rules describes the function graphed below
Answer:
Output = (0.5)(Input) + 1.5
Step-by-step explanation:
input = 1 , output = (0.5)(1) + 1.5 = 2
input = 3 , output = (0.5)(3) + 1.5 = 3
input = 5 , output = (0.5)(5) + 1.5 = 4
input = -1 , output = (0.5)(-1) + 1.5 = 1

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
-1 -9
0 -1
1 7
g(x) = 3x-2
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Please hurry as I only have a few hours left too turn in :) Thank you.
Answer:
Use 2 points from he table to find the slope of f(x):
(0, -1) and (1, 7)The slope is:
m = (7 - (-1))/1 = 8The y - intercept is b = -1 according to point (0, -1).
Part AThe lines are:
f(x) = 8x - 1g(x) = 3x - 2The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.
Part BSee above

The area of a rectangle is 33 m”, and the length of the rectangle is 5 m less than double the width. Find the dimensions of the
• rectangle
Answer:
Width: 5:5
Length: 6
Area: (6) (5.5 = 33m^2
Step-by-step explanation:
Width: x
Length: 2x - 5
(2x-5)(x) = 33
2x^2 - 5x - 33 = 0
(2x - 11) (x + 3) = 0
2x - 11 = 0
x = 11/2 = 5.5
x + 3 = 0
x = -3
[(2*5.5)-5](5.5) = 33

Answer:
2) x = 7
3) x = 5
Step-by-step explanation:
When a transversal crosses parallel lines, all of the acute angles are congruent, and all of the obtuse angles are congruent. When it crosses at right angle, all of the angles are right angles.
2) All of the angles are right angles.
11x +13 = 90
11x = 77 . . . . . . subtract 13
x = 7 . . . . . . . divide by 11

3) The two marked angles are acute.
16x = 80 . . . . the acute angles are congruent

Answer:
y ≥ -1/2x + 2y > 2x - 3Step-by-step explanation:
Find equations of each line using two points on each and then determine the inequalities.
Line 1Points
(0, 2) and (2, 1)The slope is:
m = (1 - 2)/2 = -1/2The y -intercept is 2.
The line is:
y = -1/2x + 2The shaded region is to the right and the line is solid, so the inequality is:
y ≥ -1/2x + 2Line 2Points:
(0, -3) and (2, 1)The slope is:
m = (1 - (-3))/2 = 2The y- intercept is -3The line is:
y = 2x - 3The shaded region is to the left and the line is not solid, so the inequality is:
y > 2x - 3A soap manufacturer advertises that it has increased the size of their bottle of
dishwashing soap to 18,4 ounces, which is 5% more than the original size,
What is the original size of the bottle?
Round your answer to the nearest tenth
The original size of the bottle is 17.5 ounces.
The soap manufacturer has increased the size of his bottles. This means that 18.4 ounce bottle is bigger than the original size of the bottle. The bottle was increased by 5%, this means that the new bottle is 105% (100% + 5%) bigger than the initial size of the bottle.
To determine the original size of the bottle, this formula would be used:
New bottle size / total percentage increase in the bottle = initial size of the bottle
18.4 / 1.05 = 17.5 ounces

See attached photo! (it is hard to explain in words haha)
Side note: All natural numbers are rational numbers, but not all rational numbers are natural numbers (this applies differently to all sections, like all integers are whole, but not all whole are integers, etc)
Side note #2: Whole numbers are just natural numbers AND zero
Hope this is correct (or at least helps), have a nice day! :D

fx) varies directly with x and f(x) = 50 when x = -10, then what is f(x) when x = 15?
Answer:
f(x)=-75
Step-by-step explanation:
since f(x) varies directly with x
it implies that f(x)=Kx
k=f(x)/x
when f(x)=50 and x=-10
k=50/-10
k=-5
but when x=15, f(x)=-5×15
f(x)=-75
