The hourly wage of some Toyota automobile assembly line workers is being increased annually by the same percentage
If their wage went from $6.80 to $10.19 in 7 years what is the doubling time?
(nearest year)
Answers
The doubling time of the hourly wage of the workers is an illustration of an exponential function that has a rate of 2
The doubling time of the wage is 4 years
How to determine the doubling timeA doubling function is represented as:
[tex]p = w \times 2^{\frac{x}{t}}[/tex]
Where:
p represents the final amount i.e. p = 10.19w represents the initial amount i.e. w = 6.80t represents the duration i.e. t = 7x represents the doubling timeSo, we have:
[tex]10.19 = 6.80 \times 2^{\frac{x}{7}}[/tex]
Divide both sides by 6.80
[tex]1.50 = 2^{\frac{x}{7}}[/tex]
Take the logarithm of both sides
[tex]\log(1.50) = \log(2^{\frac{x}{7}})[/tex]
Apply the law of logarithm
[tex]\log(1.50) = \frac{x}{7}}\log(2)[/tex]
Multiply both sides by 7
[tex]7 \times \log(1.50) = x\log(2)[/tex]
Divide both sides by log(2)
[tex]x = 7 \times \log(1.50) \div \log(2)[/tex]
[tex]x = 4.09[/tex]
Approximate
[tex]x \approx 4[/tex]
Hence, the doubling time is 4 years

In a football club there are 2 balls for every 12 players.To Find:
How many footballs will be needed for 48 players?
Solve:
Since there are 2 balls for every 12 players..
Let's b = balls and P = Players
2b = 12p
4b = 24p
6b = 36p
8b = 48

We can use ratios to solve.
2 balls x balls
------------- = -----------------
12 players 48 players
Using cross products
2 * 48 = 12 *x

A circle is represented by the equation x2 + 8x + y2 – 12y = –29. Describe the algebraic technique(s) needed to rewrite the equation in standard form. Identify the center and radius of the circle. Show your work
Answers
The equation of the circle can be written in standard form and in a general form
The center of the circle is (-4,6) and the radius is [tex]\sqrt{23[/tex]
How to identify the radius and the center of the circleThe equation of the circle is given as:
[tex]x^2 + 8x + y^2 - 12y = -29[/tex]
Rewrite as:
[tex]x^2 + 8x + k - k + y^2 - 12y + k - k= -29[/tex]
Express k as the square of the half of the coefficients of x and y.
So, we have:
[tex]x^2 + 8x + (4)^2 - (4)^2 + y^2 - 12y + (6)^2 - (6)^2= -29[/tex]
Evaluate the exponents
[tex]x^2 + 8x + 16 - 16 + y^2 - 12y + 36 - 36 = -29[/tex]
Collect like terms
[tex]x^2 + 8x + 16 + y^2 - 12y + 36 = -29 + 16 + 36[/tex]
Express as perfect squares
[tex](x + 4)^2 + (y - 6)^2 = -29 + 16 + 36[/tex]
[tex](x + 4)^2 + (y - 6)^2 = 23[/tex]
The standard equation of a circle is:
[tex](x - a)^2 + (y - b)^2 + r^2[/tex]
Where:
Center = (a,b)
Radius = r
So, we have:
Center = (-4,6)
Radius = [tex]\sqrt{23[/tex]
Hence, the center of the circle is (-4,6) and the radius is [tex]\sqrt{23[/tex]

A gymnastics coach records the scores of a gymnast and develops the probability distribution below. what is the probability the gymnast scores a 9 or 9.5? probability distribution gymnastics score: x probability: p(x) 5 0.02 5.5 0.02 6 0.06 6.5 0.1 7 0.16 7.5 0.14 8 0.18 8.5 0.18 9 ? 9.5 0.02 0.02 0.04 0.12 0.14
Answers
The sum of all the probabilities must be one. Then the probability that the gymnast scores a 9 or 9.95 is 0.14.
What is a probability distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
Researching on the internet, the probability of the gymnast getting each score is given by:
P(X = 5) = 0.02P(X = 5.5) = 0.02P(X = 6) = 0.06P(X = 6.5) = 0.1P(X = 7) = 0.16P(X = 7.5) = 0.14P(X = 8) = 0.18P(X = 8.5) = 0.18P(X = 9) = xP(X = 9.5) = 0.02Considering that it is a distribution, the sum of all the probabilities must be one.
0.02 + 0.02 + 0.06 + 0.1 + 0.16 + 0.14 + 0.18 + 0.18 + x + 0.02 = 1
0.88 + x = 1
x = 0.12
The probability that the gymnast scores a 9 or 9.95 will be
P(9 or 9.5) = (X = 9) + P(X = 9.5) = 0.12 + 0.02 = 0.14

The function y = 58. 7(1. 03)^t gives a country’s population, y (in millions), where t is the number of years since January 1994. According to this function, what was the approximate population of the country in January 2002
Answers
Answer:
Approximate population ≈ 74.36 million.
Step-by-step explanation:
The given problem involves modeling of an exponential growth or decay function of a population.
Definition:Exponential growth ( relative growth ) occurs when a population grows or increases exponentially by the same factor, over the same amount of time. Exponential decay occurs when a population decreases continuously by a constant factor, over the same amount of time.We can model the exponential growth of a population using the following Exponential Growth Model:
⇒ [tex]\displaystyle\mathsf{P(t)\:=\:P_0 (1\:+\:r)^t }[/tex]Where:
P( t ) = population after "t" years P₀ = initial population r = relative growth rate; positive "r" value means that the population is increasing; negative "r" value implies that the population is decreasing. t = time (typically in years)Solution:Based from the given equation, [tex]\displaystyle\mathsf{y\:=\:58.7(1.03)^t }[/tex] , we can infer that:
⇒ [tex]\displaystyle\mathsf{P(t)\:=\:P_0 (1\:+\:r)^t }[/tex] or [tex]\displaystyle\mathsf{y\:=\:P_0 (1\:+\:r)^t }[/tex]
Where:
P( t ) or y = population after "t" yearsP₀ = initial population = 58.7r = relative growth rate = 0.03 or 3% = the population is increasing (exponential growth).t = time (typically in years) = 8 years (difference between January 2002 and January 1994).Step 1: Substitute the given values into the Exponential Growth Model formula, and solve for P( t ) :
[tex]\displaystyle\mathsf{P(t)\:=\:P_0 (1\:+\:r)^t }[/tex]
⇒ [tex]\displaystyle\mathsf{P(8)\:=\:58.7 (1\:+\:.03)^8 }[/tex]
Step 2: Follow the order of operations, addition inside the parenthesis:
⇒ [tex]\displaystyle\mathsf{P(8)\:=\:58.7 (1.03)^8 }[/tex]
Step 3: Follow the order of operations, applying the exponent into the parenthesis (do not round off the digits inside the parenthesis):
⇒ [tex]\displaystyle\mathsf{P(8)\:=\:58.7 (1.266770081) }[/tex]
Step 4: Follow the order of operations, multiplying 58.7 (P₀) into the parenthesis:
⇒ [tex]\displaystyle\mathsf{P(8)\:\approx \:74.35940378\quad or \quad 74.36\:\:million}[/tex]
Final Answer:Therefore, the approximate population of the country in January 2002 is 74.36 million.

Answers
The path difference if the distance between slits on a diffraction grating is 0.60 mm, and one of the angles of diffraction is 0.30° is 1.57 × 10⁻⁶ m.
What is constructive interference?When the maxima of two waves add up (the two waves are in phase), the amplitude of the resultant wave equals the total of the separate amplitudes, this is known as constructive interference.
We know that for constructive interference, therefore, the formation of bright fringe through a diffraction grating is given by:
d sin θ = n λ
where d is the distance between slits, θ is the angle of diffraction, n is the order of fringe, and λ is the path difference.
As it is given that the distance between slits on a diffraction grating is 0.60 mm, and one of the angles of diffraction is 0.30°, therefore, the path difference can be written as,
[tex]\begin{aligned}\lambda &= \dfrac{(d sin \theta)}{ n} \\\\&=\dfrac{0.60 \times 10^{-3 }m) \times sin (0.30)}{2}\\\\ &= 1.57 \times 10^{-6}\rm\ m\end{aligned}[/tex]
Hence, the path difference is 1.57 × 10⁻⁶ m.

It is given that
Hieght of an object H = 5cm
Distance of an object =18cm
Focal lenght of lens = 10cm
As we know that the lens formula is given by
[tex]\dfrac{1}{f} =\dfrac{1}{v} +\dfrac{1}{u}[/tex]
[tex]\dfrac{1}{v} =\dfrac{1}{10} -\dfrac{1}{18}=\dfrac{8}{180}[/tex]
so now
[tex]v= \dfrac{180}{8} =22.5\ cm[/tex]
Now to find the height of the image
[tex]\rm magnification =\dfrac{v}{u} =\dfrac{-Image\ Hieght }{object\ height}[/tex]
[tex]\rm magnification =\dfrac{22.5}{18} =\dfrac{-x}{5}[/tex]
