veronica is an architect and built a scale model of a new concrete venue. in her model, 3 inches represents 50 feet
The height of Veronica's scale model in inch is 10.5 inch.
What is scale factor?A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.
Given:
3 inches = 50 feet.
So, 1 feet = 3/50 inch
Then, height of Concert Venue in feet
175 feet = 175 x 3/50
= 525/50
= 105/ 10
= 21/2
= 10.5 inch
Hence, the height is 10.5 inch.

Given the line 2x – 3y = 9 and the point (4, –1), find lines through the point that are
(a) parallel to the given line and
(b) perpendicular to it.
We will find the parallel line:
y = (2/3)*x - 11/3
And the perpendicular line:
y = (-3/2)*x + 5
How to find the two linear equations?Here we start with the linear equation, we will get:
2x - 3y = 9
We can rewrite it to get:
-3y = 9 - 2x
y = 9/-3 - 2x/-3
y = -3 + (2/3)x
Remember that two lines are parallel if the lines have the same slope, so the equation of the parallel line will be something like:
y = (2/3)*x + b
And this line must pass through (4, -1), replacing these values we will get:
-1 = (2/3)*4 + b
-1 = 8/3 + b
-1 - 8/3 = b
-3/3 - 8/3 = b
-11/3 = b
So the linear equation parallel is:
y = (2/3)*x - 11/3
Now let's find the perpendicular line. Remember that two lines are perpendicular if the product between the slopes is equal to -1, then if the slope of the perpendicular line is m, we need to solve:
m*(2/3) = -1
m = -3/2
Then the perpendicular line is something like:
y = (-3/2)*x + b
To find te value of b, we need to replace the values of the point (4, -1) there, we will get:
-1 = (-3/2)*4 + b
-1 = -6 + b
-1 + 6 = b
5 = b
So the perpendicular line is:
y = (-3/2)*x + 5

Which of the following recursive functions could describe this sequence for term a n ? Consider the sequence 7, 4, 1, -2, ….
One possible recursive function for this sequence is a n = a n-1 - 3, where a n is the nth term in the sequence and a n-1 is the previous term.
What is function?A function is a rule or mapping that relates a set of inputs to a set of outputs. It is a mathematical expression that takes one or more inputs and produces a corresponding output. Functions are essential for solving problems in mathematics, science, engineering, and computing. They can be used to describe relationships, simplify calculations, and to create models that enable us to understand the behavior of complex systems.
This recursive function states that each successive term in the sequence is three less than the previous term. Therefore, the sequence will continue to decrease by three each time. For example, the sixth term would be -11 (a 5 -3) and the tenth term would be -21 (a 9 -3).

Shawna's hourly wage is 18.00 per hour. If she work overtime, she earn time-and-a-half. Show all work for full credit.
a. How much does she earn if she works 40 hours?
b. How much does she earn if she works 46 hours?
Answer:
a) $720.00
b) $882.00
Step-by-step explanation:
For part a) Shawna works 40 hours at $18.00 per hour.
Multiply to find the amount of money she made that week.
40 hrs × $18/hr
= 40 × 18
= 720
Shawna made $720.00
For part b) we can use the answer for part a, but she worked 6 hours more beyond the fulltime 40 hours. The 6 additional hours should be paid as overtime.
Her regular rate is $18/hr. Her overtime rate is "time-and-a-half" Multiply to find that pay rate.
18 × 1.5
= 27
For overtime, Shawna will earn $27/hour.
SO now part b)
She worked 46 hours.
40 × 18 = 720 and
6 × 27 = 162
Regular pay + overtime
= 720 + 162
= 882
Shawna will earn $882.00

Expressing large numbers in terms of powers is known as an exponent. Therefore, the exponent describes the number of times a number has been multiplied by itself.
Exponentiation is a mathematical operation that involves the base number (b) and the exponent (or power) number (n), and is written as bn. Its pronunciation is "b (raised) to the (power of) n." Exponentiation corresponds to base multiplication when n is a positive integer; therefore, bn is the result of multiplying n bases:
