Answer:
16.4%
Step-by-step explanation:
Assuming the 5% was taken off of the already-discounted price, then the original price was multiplied by ...
(1 -12%)(1 -5%) = 0.88×0.95 = 0.836 = 1 -16.4%
The total decrease was 16.4%.
The population of a certain country since 1990 can be approximated by f(t)=0.008t2+2.1t+175 where f(t) is the population in millions and t represents the number of years since 1990. Find the average rate of change in the country's population between 1990 and 2010. Round to 1 decimal place.
Answer:
[tex]\frac{f(20)-f(0)}{20-0} = \frac{220.2-175}{20} = 2.26[/tex]
Step-by-step explanation:
as with all functions f(t), the average rate of change on [a.b] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Find the value of x. Everything is in the photo.
Answer:
27
Step-by-step explanation:
Note that since VX and XZ are both line segments, <VWX and <XYZ both equal 180 (also known as a straight angle). Also, note that the sum of the angles in a triangle are 180 degrees. Now, let’s start.
Finding angles of the triangle:
<WYX = <XYZ - <WYZ = 180 - 4x
<XWY = <XWV - <VWY = 180 - 6x
Using the sum of angles in a triangle and substituting these values in:
180 = <X + <WYX + <XWY = 90 + (180 - 4x) + (180-6x) = 450 - 10x
270 = 10x
27 = x
We are done! I hope this helps! :)

Complete the table shown to the right for the population
growth model for a certain country
2004 Population(millions) 42.4
Projected 2022 Population
(millions)____
Projected Growth Rate, k 0.0145
The projected 2022 population is ____ million
Answer:
2,1
Step-by-step explanation:
Answer: ≈ 55.045
Step-by-step explanation:
The formula is A=Pe^rt
A = (?) projected population
P = 42.4 (current population)
r = 0.0145 (growth rate)
t = 18 (difference between years: 2022 - 2004)
A = 42.4e^0.0145(18)
A = 42.4e^0.261
A = 42.4(1.298227665)
A ≈ 55.045

Answer:
g(x) = (x-8)^2 - 5
Step-by-step explanation:
subtracting from x inside of the square translates the function to the right and adding to x inside of the square translates it to the left.
(x-8)^2 - 1 translates the function 8 units to the right
subtracting from the constant translates the function down and adding translates it up.
x^2 - 5 translates the function 4 units down
Therefore, (x-8)^2 - 5 translates the function 8 units to the right and 4 units down
"select all the numbers that are solutions to the equation x^3=27"
The x = ∛27 and x = 3 are solution to the equation x³=27 option (B) and option (C) are correct.
What is a cube root?It is defined as the sum of two or more numbers. The original number is obtained by multiplying the cube root of a number three times; for example, the cube root of x is z.
We have equation:
x³ = 27
Taking cube root both side
∛x³ = ∛27
x = ∛27
x = 3
Thus, the x = ∛27 and x = 3 are solution to the equation x³=27 option (B) and option (C) are correct.

An elevator is traveling underground at a constant rate. The equation y= -2x - 10 can be used to represent this situation, where y is the position of the elevator underground in feet and x is the number of seconds the elevator has been traveling Which statement best describes the position of the elevator, given this equation?
O From a starting position of 2 feet underground, the elevator is descending 10 feet per second
O From a starting position of 10 feet underground, the elevator is descending 2 feet per second
O From a starting position of 2 feet underground, the elevator is ascending 10 feet per second
O From a starting position of 10 feet underground, the elevator is ascending 2 feet per second
4 is correct
reason is because the number next to x is the constant number and the end number is where you started
