Answer:
1.2 times or 20%
Step-by-step explanation:
Given the function ; f(x) = 830(1.2)^x
This is an exponential function ;
Recall the general form of an exponential function ; f(x) = ab^x ;
Where a = Initial value ; b = growth rate
Hence, b = 1.2
Also, b = 1 + r
1.2 = 1 + r
r = 1.2 - 1
r = 0.2
r = 0.2 * 100% = 20%

Daily income of 8 workers is Rs. 2400. How many workers will earn Rs.1800
Answer:
6 workers
Step-by-step explanation:
Number workers to earnings is direct proportion.
8: 2400 :: x : 1800
Product of means = Product of extremes
2400 * x = 8*1800
[tex]x = \frac{8*1800}{2400}\\\\x=6[/tex]
Answer:
6 workers will earn Rs. 1800.
Step-by-step explanation:
Given :-
Daily income of 8 workers is Rs. 2400.To find :-
How many workers will earn Rs.1800.Solution :-
Let
no. of workers will earn Rs. 1800 = x.
We need to write a ratio to solve.
8 = 2400x = 1800using cross products
8 × 1800 = x × 240014400 = 2400xDivide each side by 2400
14400/2400 = 2400x/24006 = xHence, 6 workers will earn Rs. 1800.

in the given graph of a cubic polynomial, what are the number of real zeros and complex zeros respectively
Answer:
1 real and 2 complex
Step-by-step explanation:
The Fundamental theorem of Algebra states that a polynomial of degree n has n zeros, some may be complex.
A cubic is a polynomial of degree 3 , then has 3 zeros.
From the graph
There is a real zero at x = 4
Thus the other 2 must be complex
Which statement best describes how to determine whether f(x) = x² – X + 8 is an even function?
1. Determine whether -x²-(-x)+8 is equivalent to x²-x+8
2. Determine whether (x)²-x+8 is equivalent to x²-x+8
3. Determine whether -x²(-x)+8 is equivalent to -(x²-x+8)
4. Determine whether (-2)²-(-x)+8 is equivalent to -(x²-x+8)
Answer:
Option 1
Step-by-step explanation:
You can tell if a function is even if [tex]f(-x)=f(x)[/tex]:
[tex]f(x)=x^2-x+8[/tex]
[tex]f(-x)=(-x)^2-(-x)+8[/tex]
[tex]f(-x)=x^2+x+8[/tex]
Since [tex]f(-x)\neq f(x)[/tex], the function is not even. Therefore, option 1 is the best option.

Do the side lengths 15,20 and 25 form a right triangle?
PLEASEEEE HELPPPP!!! asap
===================================================
Work Shown:
a^2+b^2 = c^2
15^2+20^2 = 25^2
225+400 = 625
625 = 625
Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.
Side note: c is always the longest side.

Angelica reads 15 pages of a book each day. In 10 days, she reads 200 pages. Assume the relationship is linear. Find and interpret the rate of change and initial value.
help me please
Given:
Angelica reads 15 pages of a book each day.
In 10 days, she reads 200 pages.
Assume the relationship is linear.
To find:
The rate of change and initial value.
Solution:
The slope intercept form of a linear function is:
[tex]y=mx+b[/tex] ...(i)
Where m is the slope and b is the y-intercept.
Angelica reads 15 pages of a book each day. So, the rate of change is 15 pages per day and [tex]m=15[/tex].
In 10 days, she reads 200 pages. It means the linear relation passes through the point (10,200).
Putting [tex]x=10,y=200,m=15[/tex] in (i), we get
[tex]200=15(10)+b[/tex]
[tex]200=150+b[/tex]
[tex]200-150=b[/tex]
[tex]50=b[/tex]
So, the y-intercept is 50. It means the initial number of pages angelica already read is 50.
Therefore, the rate of change is 15, it means Angelica reads 15 pages per day. The y-intercept is 50, it means the initial number of pages angelica already read is 50.

An NBA basketball court is rectangular in shape where the length is 2m less than twice the width. If the perimeter of the court is 86m, what are the dimensions (length and width) of the court?
Answer:
Length = 28 m
Width = 15 m
Step-by-step explanation:
Court is rectangular in shape.
Now, we are told that;
Length is 2m less than twice the width(W) .
Thus;
Length; L = 2W - 2
We are told the perimeter is 86 m.
Formula for perimeter of a rectangle is;
P = 2(L + W)
Thus;
2((2W - 2) + W) = 86
Divide both sides by 2 to get;
(2W - 2) + W = 43
3W - 2 = 43
3W = 43 + 2
3W = 45
W = 45/3
W = 15 m
Thus; L = 2(15) - 2
L = 30 - 2
L = 28 m

For f(x) = 3x + 1 and g(x) = x ^ 2 - 6 find (8/f)(x)
Answer:
9x² + 6x - 5
Step-by-step explanation:
If you mean g(f(x))
g(x) = x² - 6
f(x) = 3x + 1
Then, g(f(x)) = g(3x + 1)
but g(x) = x² - 6
g(3x + 1) = (3x + 1)² - 6 = 9x² + 6x + 1 - 6
= 9x² + 6x - 5

A film starts at 19:30 the film lasts 104 minutes at what time does the film end?
Answer:
Hello There!!
Step-by-step explanation:
I believe the answer is 21:14. Split 104 minutes so it will be easier to calculate so it's 60 and 44. 60 minutes is 1 hour so add 1 hour to 19:30 which is 20:30 then there is 44 minutes left. There is 30 minutes left to make it 21:00 so there is 14 minutes left at the end and add that to 21:00 which is 21:14.
hope this helps,have a great day!!
~Pinky~
If a film starts at 19:30 and lasts 104 minutes.
The film will end at 21:14.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Example:
x + y + 2 is an expression.
We have,
Film start time = 19:30
Duration of the film = 104 minutes
1 hour = 60 minutes
Multiply 104/60 on both sides
104/60 x 1 hour = 104/60 x 60 minutes
1.73 hours = 104 minutes
The time the film will end:
= 19:30 + 1.73 hours
= 19:30 + 1 hour + 44 minutes
= 21:14
Thus,
The film will end at 21:14.

What term describes the process of using the output of one function as the input for another? A. Function mapping B. Function simplification C. Function composition D. Function notation
Answer: C. Function composition
Step-by-step explanation:
If we have two functions, we can form a new function by composing one function into the other. Such functions are known as composite functions.
For example we have two functions f and g and produces a function h such that h(x) = g(f(x)).
It is generally a function that is written inside another function.
i.e. it is a process of using the output of one function as the input for another.
Thus, the correct option is C.
The required term: Function composition
