Answer:
option C: Asian
explanation:
Asian countries, such as China, produce goods like the European products, but for much cheaper prices.
The population f(x), in millions, of State A of a country after x years is represented by the function shown below:
f(x) = 4(1.08)x
The graph shows the population g(x), in millions, of State B of the country after x years:
graph of exponential function g of x that curves up from left to right and goes through points 0 comma 2 and 9 comma 4
Which conclusion is correct about the populations of State A and State B?
Option 1 is correct. The correct solution about these functions is that The original population of State A was double of the original population of State B.
How to solve for the solutionThe function in the question is given as
For A:
[tex]F(x) = 4*(1.08)^x[/tex]
For B
[tex]g(x) = 2*(1.08)^x[/tex]
The exponential growth equation that is used to solve this is
[tex]h(x) = A(r)^x[/tex]
such that A is the initial and r is the rate of growth.
f(x) and g(x) are at the same rate but the exponential function is known to grow faster.
Hence the correct option is The original population of State A was double of the original population of State B.
Complete question:Which conclusion is correct about the population of State A and State B? 1. The original population of State A was double of the original population of State B.
2. The original population of State A was half of the original population of State B.
3. The original population of State B was one-fourth of the original population of State A.
4. The original population of State A was one-fourth of the original population of State B.

Answer:
f⁻¹(1/5) = 2
Explanation:
If f(x) = (2x -3)/5
To find inverse of f(x), make x the subject.
[tex]f(x) = \dfrac{2x - 3}{5}[/tex]
[tex]5 f(x) = 2x - 3[/tex]
[tex]2x = 5 f(x) + 3[/tex]
[tex]x = \dfrac{5 f(x) + 3}{2}[/tex]
Then,
[tex]f^{-1}(x) = \dfrac{5x+3}{2}[/tex]
To find f⁻¹(1/5), simplify insert [x = 1/5 or 0.2]
[tex]f^{-1}(0.2) = \dfrac{5(0.2)+3}{2}[/tex]
which yields
[tex]f^{-1}(0.2) = 2[/tex]

number that describes both the direction and the steepness of the line
slope = rise/run
b represents the y-intercept
point where crosses the y-axis
The y-intercept is -1rise = -1, run = 1 so rise / run = -1 / 1 = -1line is downward slopey = mx + b → y = -1x + (-1)

The construction is to draw a parallel line to a given line AB passing through point P. To fix the error, the 3rd arc must be reconstructed. Thus the correct option is D. The third arc should be drawn centered at F.
The given construction involves drawing a parallel line through a given point P to a given line AB.
From the construction shown, drawing a straight line through P and G would not be parallel to the given line AB. Thus there is an error in the construction of the 3rd arc. To draw the required corresponding angle, the 3rd arc has to be reconstructed.
Therefore to fix the error the correct step to follow is: Option D. The third arc should be drawn centered at F.

A body of mass 50 kg explodes and splits into three pieces. The first piece has a mass of 10 kg and a velocity of [-3,2] m/s, the second piece has a mass of 18 kg and a velocity of [5,-4]m/s. What is the velocity of the third piece?
Step-by-step explanation:
From the conversation of angular momentum
Initial momentum=final momentum
Here,
Since body is initially resting, it's momentum must be zero.
Let v be velocity of third piece. Then
0= 10(-3i+2j) + 18(5i-4j) + 22v
Solving this we get,
v= 4/22(15i+13j).
The velocity of third piece is 2/11(13 j - 15i)
What is velocity?Velocity defines the direction of the movement of the body or the object.
Given:
As the body is at rest so the initial momentum is zero.
Let v be velocity of third piece.
so,
0= 10(-3i+2j) + 18(5i-4j) + 22v
0= -30i + 20j + 90i -72j + 22 v
0= 60i - 52j + 22 v
-60i +52j = 22v
v= 2/11( 13j - 15 i)

58. Image attached.
First, let's simplify some things. Let's make this a quadratic equation.
Moving the -1 (by adding 1 to both sides) gives us 5x^2 + 8x + 1 = 0. Note that this is the standard form of a quadratic, which is ax^2 + bx + c = 0.
Now, the discriminant. The discriminant is helpful because it tells us if we have 2 real solutions, 1 real solution, or if this equation is imaginary and thus impossible to solve using elementary techniques. If the discriminant is greater (>) than 0, then it has 2 solutions. If the discriminant equals (=) 0, it has 1 solution. If the discriminant is less than (<) 0, then it is imaginary.
The discriminant of a quadratic equation is defined as b^2 - 4ac (from the quadratic formula.) We just plug in b, a and c. b will be 8, a will be 5, and c will be 1. Now we just solve. (8)^2 - 4 * 5 * 1 = 64 - 20 = 44. Since 44 is greater than 0, we have 2 solutions for this. 44 is the discriminant. (Answer to 56.) We also have 2 solutions (answer to 57.)
Now, I'll solve the quadratic equation using the quadratic formula. I'll attach my work in an image (answer to 58.)

25. A wheelchair access ramp has an angle of elevation of 16°. If the ramp
reaches to the top of a 22 inch high porch, how long is the ramp?
79.82 in.
76.81 in.
73.82 in.
81.5 in.
Answer:
C. 76.81
Step-by-step explanation:
We must use one of the trigonometric ratios to find the length, L, of the ramp. If we use 16 as the reference angle, the 22 in would be our opposite side and the ramp length is the adjacent.
Therefore, we must use tan, which is [tex]\frac{opposite}{adjacent}[/tex]:
[tex]tan (16)=\frac{22}{L} \\\\L*(tan(16)=22)\\\\L*tan(16)=22\\[/tex]
[tex]\frac{L*tan(16)}{tan(16)}=\frac{22}{tan(16} \\\\L=79.815=79.82 in.[/tex]
