Answer:
The initial value of the exponential function is 2
Step-by-step explanation:
A function is a mathematical relation in which we input the values of a domain that generate the output values of a range.
Initial value of the function is the output value of the function when the input is x =0.
As shown in the graph:
The exponential function cut at the point (0, 2)
where;
y=2 when x=0.
Therefore, the initial value for the exponential as shown in the figure is, 2.

To solve the inequality -3 < 2x + 1 < 7 for the number x, subtract 1 from all parts and then divide by 2. The solution is the range of numbers greater than -2 and less than 3.
Explanation:The problem statement here results in an inequality that can be expressed algebraically. If 'x' represents the unknown number, we can write the inequality as -3 < 2x + 1 < 7.
To solve for 'x', we will isolate the variable on one side by following the rules of inequalities similar to solving equations.
First, subtract 1 from all parts of the inequality to get the pure inequality without a constant.
-4 < 2x < 6
Now, divide all parts of the inequality by 2, which yields:
-2 < x < 3
All numbers greater than -2 and less than 3 satisfy the original problem statement. Therefore, the range of numbers that solve the inequality is from -2 to just below 3.

anonymous 4 years ago A technical writer makes $45,000 per year and has just begun contributing 8% of her salary to her 401(k) plan. If her employer matches 6% of her contributions, how much will have been contributed to the 401(k) plan after 2 years?
Answers
Answer:
$7,632 would have been contributed to the 401(k) plan after 2 years.
Step-by-step explanation:
A technical writer makes salary per year = $45,000
She contributing 8% of her salary to her 401(k) plan = 8% of 45,000
0.08 × 45,000 = $3,600
Her employer matches 6% of her contributions = 6% of 3,600
= 0.06 × 3,600 = $216.00
Total contribution for one year = 3,600 + 216.00 = $3,816
After 2 years = 3,816 × 2 = $7,632.00
$7,632 would have been contributed to the 401(k) plan after 2 years.

the expression 12x+15x-11x can be combined because of which property
A. commutative property of addition
B. distributive property
C. additive inverse property
D. multiplicative property
Answers
The expression 12x+15x-11x can be combined using the associative property of addition.
Explanation:The expression 12x+15x-11x can be combined by using the associative property of addition.
First, combine the like terms which have the same variable, in this case 'x'. Add the coefficients of the like terms, which are 12, 15, and -11. 12x + 15x - 11x = (12 + 15 - 11)x = 16x.Therefore, the simplified expression is 16x. The associative property of addition allows us to group the terms in any order and still get the same result.
Final answer:
The expression 12x + 15x - 11x can be simplified due to the associative property of addition, enabling terms to be grouped and combined to yield a simplified form of 16x. The correct option is not provided in the choices, but would be the associative property, not listed in the student's options.
Explanation:
The expression 12x + 15x - 11x can be simplified by combining like terms, which is possible because of the associative property of addition. This property allows us to group numbers in an addition expression in any way we choose without changing the result.
Therefore, using the associative property, we can group and combine the terms with 'x' to get (12x + 15x) - 11x, which simplifies to 27x - 11x, and then further to 16x.
The correct answer to the question is Option A: associative property of addition, though it is important to note that this option was not listed in the initial question provided. The commutative property allows us to change the order of the terms without changing the result, but does not directly apply to the combination of like terms.
Nevertheless, both the associative and commutative properties are used when combining like terms in algebra.

In the context of congruent polygons, side EF of polygon CDEF is congruent to side PQ of polygon MNPQ due to the corresponding order of sides in congruent figures.
Explanation:
The question refers to congruent figures in geometry, specifically congruent polygons. If polygons are congruent, all corresponding sides and angles are congruent as well. Therefore, if CDEF ≅ MNPQ, then side EF must be congruent to the side of polygon MNPQ that corresponds to EF in the order of letters given. Following the order, side EF corresponds to side PQ.

Luigi is an urban planner. as an independent contractor, he charges $140 fee plus $ 25 per hour for each contract with the city.
Write a function to represent this scenario where Y represents the total amount her changes for a project and x represents the number of hours worked on a project
Answers
x = hours 25 per hour = 25x
y = total
so y = 25x +140
Answer: y = 140+25x
Step-by-step explanation:
Since According to the question, Luigi initally charged $140.
And, per hour he charged an additional amount $25 for each contract with the city.
Here, x represents the number of hours worked on a project.
Thus the additional amount after x hours = 25x
So, the total amount he charged in x hours= 140+ 25x
And, according to the question y represents the above change.
Thus, we get a function for the given situtaion
which is , y= 140+ 25x , where x is number of hours and y is total amount charged.

Step-by-step explanation:
As given
Mrs. Howard is hosting a catered dinner party to celebrate her daughter's graduation.
The catering company she plans to use charges $13.50 per plate of food and an additional fee of $540 to cover linens and tableware.
The total bill for the catering services is $1,512.
Total number of guests, g .
Than the equation becomes
1512 = 540 + 13.50 g
1512 - 540 = 13.50 g
972 = 13.50 g
[tex]g = \frac{972}{13.50}[/tex]
g = 72
Therefore the equation can be used to determine the total number of guests is 13.50g + 540 = 1512 and the total number of guest are 72 .

Reason: ?
3. Angle 2 is congruent to Angle 4.
Reason: ?
Answers
Angle 2 and Angle 4 are congruent because they form a linear pair and their sum is 180 degrees.
Explanation:Given that Angle 2 and Angle 3 are a linear pair and Angle 3 and Angle 4 are a linear pair, we can prove that Angle 2 is congruent to Angle 4.
Since Angle 2 and Angle 3 are a linear pair, they form a straight line and therefore their angles add up to 180 degrees. So, Angle 2 + Angle 3 = 180 degrees. (Supplementary)
Similarly, Angle 3 and Angle 4 are a linear pair, so Angle 3 + Angle 4 = 180 degrees. (Supplementary)
By transitive property, if Angle 2 + Angle 3 = 180 degrees and Angle 3 + Angle 4 = 180 degrees, then Angle 2 + Angle 3 + Angle 4 = 180 degrees.
Since the sum of Angle 2, Angle 3, and Angle 4 is 180 degrees, we can subtract Angle 3 from both sides of the equation to get Angle 2 + Angle 4 = 180 degrees.
Therefore, Angle 2 + Angle 4 = 180 degrees, and since the sum of the angles in a straight line is 180 degrees, we can conclude that Angle 2 is congruent to Angle 4.Learn more about Congruent Angles here:

In 2010, the national debt of the United States was about 14 trillion dollars. In 2003 it was about 7 x 10 to the 12 dollars. About how many times larger was the national debt in 2010 than 2003? THIS IS SCIENTIFIC NOTATION
Answers
Answer: About 2 times.
Step-by-step explanation:
Given : In 2010, the national debt of the United States was about 14 trillion dollars.
We know that 1 trillion [tex]=1,000,000,000,000= 10^{12}[/tex]
then, In 2010, the national debt of the United States was about [tex]14\times10^{12}[/tex]
dollars.
In 2003 it was about [tex]7\times10^{12}[/tex] dollars.
Now, the number of times the national debt was larger in 2010 than 2003 :-
[tex]\dfrac{ 14\times10^{12}}{7\times10^{12}}\\\\=\dfrac{14}{7}\times10^{12-12}\\\\=2\times10^0=2[/tex]
Hence, national debt was about 2 times larger in 2010 than 2003 .
