Answer:
The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
It is a measure of how much the function changed per unit, on average, over that interval.
A town doubles its size every 44 years. If the population is currently 8,000, what will the population be in 88 years?
Answer:
32,000
Step-by-step explanation:
In 44 years, it will double to 16,000. In 44 more years (88 years from now), it will double again to 32,000.
The population in 88 years will be 32,000.

7x - 15 = 4x - 12
3x - 15 = -12
3x = 3
x = 1
y = 7(1) - 15
y = 7 - 15
y = -8

What is the solution of log(t-3) = log(17-4t)?
Answer:
t=4
Step-by-step explanation:
Answer:
Solution: 4
Step-by-step explanation:
We are given that log(t - 3) = log(17 - 4t), and need to solve for the value of t. Start off by applying the log rule 'If log(f(x)) = log(g(x)) say, then f(x) = g(x).' Similarly the equation boils down to the following:
t - 3 = 17 - 4t
Solving this equation, we will receive our solution. Let's do it:
t - 3 = 17 - 4t,
t = 20 - 4t,
5t = 20,
t = 20/5 = 4 ✓
The previous solution is correct.
Determine whether the study is an observational study of an experiment. Explain.
In a survey of 1117 adults in a country, 54% said the country's leader should release all medical information that might affect their ability to serve The study is_____because it____a treatment to the adults.
Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.

~Combine like terms
(4x + 3x) + (-12 + 9)
~Simplify
7x - 3
Best of Luck!
Answer:
X = 3/7
Step-by-step explanation:
4X - 12 + 3X + 9 = 0 (separate them)
4X + 3X = 12 - 9 (add)
7X = 3 (divide 7 on both sides)
X = 3/7
A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i. What is the student's mistake? Select the two correct answers. A. They multiplied the second number by the real part of the first number. B. In the multiplication of the imaginary parts, the student forgot to square the i. C. The student has only multiplied the real parts and the imaginary parts. D. The student has added the real parts and multiplied the imaginary parts. E. The student has multiplied the second number by the imaginary part of the first number.
Answer:
B. In the multiplication of the imaginary parts, the student forgot to square the i. C. The student has only multiplied the real parts and the imaginary parts.Step-by-step explanation:
Before we figure out the student mistake, let us find the product of the complex numbers ourselves first.
(4+5i) (3-2i)
open the parenthesis
= 4(3)-4(2i)+3(5i)+5i(-2i)
= 12-8i+15i-10i²
Note that in complex number, i² = -1, hence the expression will become;
= 12-8i+15i-10(-1)
= 12-8i+15i+10
collect like terms by separating the real from imaginary part
= 12+10-8i+15i
= 22+7i
From the students answer i.e 12-10i, it can be concluded that;
In the multiplication of the imaginary parts, the student forgot to square the i and the student has only multiplied the real parts and the imaginary parts 4 and 3 to get 12

Monica is a lawyer who earns $8,322.65 every month. She spends $830.98 on rent, $210.36 on food, and $120.45 on gas every month. After these expenses, she has $ left from her earnings.
Answer:
Money left from her earning after expenses is $ 7160.86
Step-by-step explanation:
Money earned by Monica every month = $ 8322.65
Money spend on rent = $ 830.98
Money spend on food = $ 210.36
Money spend on gas every month = $ 120.45
Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )
= 8322.65 - 1161.79
= $ 7160.86
Answer:
Money left from her earning after expenses is $ 7160.86
Step-by-step explanation:
Money earned by Monica every month = $ 8322.65
Money spend on rent = $ 830.98
Money spend on food = $ 210.36
Money spend on gas every month = $ 120.45
Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )
= 8322.65 - 1161.79
= $ 7160.86
Therefore. Money left from her earning after expenses is $ 7160.86

y - 13 = 3 ( x - 1 )
y - 13 = 3 x - 3
y = 3 x - 3 + 13
y = 3 x + 10
y - 4 = 3 x + 6
y - 4 = 3 ( x + 2

Suppose that, in 1995, Germany produced 4.719 million computers. The total world production that year totaled 80 million computers. What percent of the world's total production of computers is contributed by Germany? Round your answer to the nearest tenth.
Answer:
To the nearest tenth
Percentage= 5.9%
Step-by-step explanation:
In 1995, Germany produced 4.719 million computers.
In that same year, the total computer production of the whole world was 80 million.
The percentage of the world production contributed by Germany
=Number produced by Germany/Number produced by the whole world * 100
The percentage of the world production contributed by Germany
=( 4.719/80)*100
The percentage of the world production contributed by Germany
=5.89875%
To the nearest tenth
= 5.9%

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mr. Edwards bought a 50-pound bag of flour for his bakery.
It was equally divided among 6 days.
So, According per day the flour will be used
= 50/6
= 25/3
= 8.33 pound
Hence, 8.33 pounds used per day.

(Ticket sales) tickets for a community theater costs $10 for each main floor seat and $8 for each balcony seat. There are 400 seats on the main floor, and these seats were sold out for the evening performance. The total revenue from ticket sales was $5200. How many balcony seats were song?
Answer:
150
Step-by-step explanation:
400*10=4000
5200-4000=1200
1200 divided by 8 =150
Answer:
150 seats were sold.
Step-by-step explanation:
first do 10x400= 4000
then 5200-4000= 1200
divide that by how much balcony tickets cost, so 1200÷8= 150 seats
Find the perimeter of the triangle to the nearest whole unit.

Answer:
14
Step-by-step explanation:
Perimeter of the ∆ = sum of the length of the 3 sides.
The length of the 3 sides can be calculated by using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to find the distance between the vertices of the ∆.
The coordinates of the 3 vertices are:
(-1, 3), (2, 2), (-2, -2)
Distance between (-1, 3) and (2, 2):
Let,
[tex] (-1, 3) = (x_1, y_1) [/tex]
[tex] (2, 2) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(2 -(-1))^2 + (2 - 3)^2} [/tex]
[tex] d = \sqrt{(3)^2 + (-1)^2} [/tex]
[tex] d = \sqrt{9 + 1} = \sqrt{10} = 3.2 units [/tex]
Distance between (2, 2) and (-2, -2)
Let,
[tex] (2, 2) = (x_1, y_1) [/tex]
[tex] (-2, -2) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(-2 - 2)^2 + (-2 - 2)^2} [/tex]
[tex] d = \sqrt{(-4)^2 + (-4)^2} [/tex]
[tex] d = \sqrt{16 + 16} = \sqrt{32} = 5.7 units [/tex]
Distance between (-2, -2) and (-1, 3)
Let,
[tex] (-2, -2) = (x_1, y_1) [/tex]
[tex] (-1, 3) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(-1 -(-2))^2 + (3 -(-2))^2} [/tex]
[tex] d = \sqrt{(1)^2 + (5)^2} [/tex]
[tex] d = \sqrt{1 + 25} = \sqrt{26} = 5.1 units [/tex]
Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units

Answer:
• The equation is a contradiction
• The solution set is Ø
Step-by-step explanation:
The simplest approach to this problem is solving for the value of y, and then identifying what type of equation it is. Remember that conditional equations have a defined value, contradiction equations have no solutions, and identity type equations have infinite solutions. Let's solve for y,
[tex]\mathrm{Given:5y\:+\:5\:-\:11y\:=\:-\:2y\:-\:7\:-\:4y},\\\\\mathrm{Add\:similar\:elements:}\\\\=> -6y+5=-2y-7-4y\\=> -6y+6y=-6y-12+6y\\=>0=-12[/tex]
Both sides are not equal, and hence we have no solutions. Our equation is contradiction, and the solution set is Ø.
Steps to solve:
~Combine like terms
-6y + 5 = -6y - 7
~Subtract 5 to both sides
-6y = -6y - 12
~Add 6 to both sides
0 = -12
There are no solutions.
