What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Given:
The Burj Khalifa, a building in Dubai,
United Arab Emirates, is about 828 meters tall.
Brody is making a scale model of this building,
using the scale factor 1:500.
The height of the model = 828 / 500 = 1.656
= 1.7 to the nearest tenth.
Therefore, the model is 1.7 meters tall to the nearest tenth.

Which function represents exponential growth?
a. f(x) = 3x
b. f(x) = x3
c. f(x) = x + 3
d. f(x) = 3x
FIRST PERSON TO ANSWER IS THE BRAINLIEST!!!!
PLEASE GIVE EXPLANATION OF HOW!!
Answers
Answer:
Either A or D, but the answer is [tex]f(x) = 3^x[/tex].
Step-by-step explanation:
We can check for exponential growth by checking for an [tex]x[/tex] in the exponent of a constant value in the function, which is this case for [tex]f(x) = 3^x[/tex].
f(x) = x + 3 function represents exponential growth. So the correct option is option is c.
An exponential function is a arithmetic function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is know the base of the function and it will be greater than 0.
An exponential function is explain by the formula f(x) = ax, where the input variable x take place as an exponent.
The exponential curve turn on the exponential function and it depends on the value of the x.
The exponential function is an main arithmetic function which is of the form
f(x) = ax
Exponential Growth
In Exponential Growth, the quantity grow very slowly at first, and then quickly. The rate of change growth over time. The rate of growth becomes faster as time passes. The quick growth is meant to be an “exponential increase”. The formula to explain the exponential growth is:
y = a ( 1+ r )x
Where r is the growth percentage.
Therefore, f(x) = x + 3 is a function represents exponential growth.

An employee at a homemade wooden toy store earned $860 over the past week. The employee needs to pay 14% for Federal Income Tax and 3% for State Income Tax, both on the initial amount he earned. How much will the employee earn after paying both taxes?
$
Answers
$713.8
Explanation:
14%of 860 = 120.4
3% of 860 = 25.8
so, subtract the sum of the above 2 values from 860.
860 - (120.4+25.8) = 860-146.2 = 713.8
Hope this helps
Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.
What is percentage?Percentage is a "number or ratio that can be expressed as a fraction of 100".
According to the question,
An employee earned $860 over the past years. The employee needs to pay 14% for income tax and 3% for state income tax
Find an employee needs to pay in Federal income tax:
[tex]\frac{14}{100}[/tex] × 860 = 120.4
Find an employee need to pay in State income tax:
[tex]\frac{3}{100}[/tex] × 860 = 25.8
In order to find an employee earn after paying both taxes only if we sum the amount of taxes paid by an employee and subtract from earned amount by past years.
860 - (120.4 + 25.8) =713.8
Hence, Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.

graph the equation y=5/2x-3
Answers
Answer:
Slope: 5/2
y-intercept: (0,-3)
The graph of the equation y=5/2x-3 is plotted.
Given data:
The linear equation is represented as y = ( 5/2 )x - 3
To graph the equation y = (5/2)x - 3, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
So, the slope is 5/2, and the y-intercept is -3.
To plot the graph, follow these steps:
Plot the y-intercept:
Start by plotting the point (0, -3), which represents the y-intercept.
Use the slope to find another point: Since the slope is 5/2, use the rise and run method. From the y-intercept point (0, -3), move up 5 units (positive 5) and then move to the right 2 units. This gives another point on the line, which is (2, 2).
Hence, the equation is y = ( 5/2 )x - 3 and the graph is plotted below.
