Write a function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11|.
Transformations are used to change the position of a function from one point to another. When f(x) is reflected over the y-axis, the new function g is [tex]g(x) = x + 8[/tex]
Given that:
[tex]f(x) = -3+|x - 11|[/tex]
To reflect across the y-axis, we use the following transformation rule:
[tex](x,y) \to (-x,y)[/tex]
So, the new function is:
[tex]g(x) = f(-x)[/tex]
If [tex]f(x) = -3+|x - 11|[/tex], then:
[tex]f(-x) = -3+|-x - 11|[/tex]
Factor out -1
[tex]f(-x) = -3+|-1(x + 11)|[/tex]
Remove absolute sign
[tex]f(-x) = -3+1 \times (x + 11)[/tex]
[tex]f(-x) = -3+x + 11[/tex]
Collect like terms
[tex]f(-x) = x + 11-3[/tex]
[tex]f(-x) = x + 8[/tex]
Hence, the new function is:
[tex]g(x) = x + 8[/tex]

Una escalera de 131313 metros está recargada contra una pared cuando su base empieza a resbalar. Cuando la base está a 121212 metros de la pared, se mueve a una razón de 5\text{ m/s}5 m/s5, start text, space, m, slash, s, end text. En ese momento, ¿a qué razón está cambiando el ángulo \thetaθtheta entre el piso y la escalera?
Answer:
El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.
Step-by-step explanation:
Sea [tex]x[/tex] la distancia horizontal entre la pared y la base de la escalera y [tex]l[/tex] la longitud de la escalera, medidas en metros. Además, tenemos que [tex]\theta[/tex] es el ángulo entre la escalera y el piso, medido en radianes.
Si la pared y el piso son ortogonales entre sí, entonces podemos utilizar la siguiente relación trigonométrica que relaciona las variables anteriores:
[tex]\cos \theta = \frac{x}{l}[/tex] (1)
Por diferenciación implícita y la definición de razón de cambio tenemos que:
[tex]-\sin \theta \,\dot \theta = \frac{\dot x}{l}[/tex] (2)
Donde:
[tex]\dot x[/tex] - Razón de cambio de la distancia horizontal entre la pared y la base de la escalera, medida en metros por segundo.
[tex]\dot \theta[/tex] - Razón de cambio del ángulo entre el piso y la escalera, medida en radianes por segundo.
Pero tenemos que el seno del ángulo está definido por:
[tex]\sin \theta = \frac{\sqrt{l^{2}-x^{2}}}{l}[/tex] (3)
Si aplicamos (3) en (2), expandimos la ecuación como sigue:
[tex]-\frac{\sqrt{l^{2}-x^{2}}}{l}\,\dot \theta = \frac{\dot x}{l}[/tex]
[tex]\dot \theta = - \frac{\dot x}{\sqrt{l^{2}-x^{2}}}[/tex] (4)
Si tenemos que [tex]\dot x = 5\,\frac{m}{s}[/tex], [tex]l = 13\,m[/tex] y [tex]x = 12\,m[/tex], entonces la razón de cambio del ángulo es:
[tex]\dot \theta = -\frac{\left(5\,\frac{m}{s} \right)}{\sqrt{(13\,m)^{2}-(12\,m)^{2}}}[/tex]
[tex]\dot \theta \approx -1\,\frac{rad}{s}[/tex]
El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.

Step-by-step explanation:
can you please answer my question too? it is due soon
Answer:
x = 12
Step-by-step explanation:
1/2x-5=10-3/4x
add 5 to both sides
1/2x=15-3/4x
add 3/4x to both sides
1/2x + 3/4x = 15
2/4x + 3/4x = 15
5/4x = 15
divide both sides by 5/4
x = 15 * 4/5
x = 60/5
x = 12

In 2014, the enrollment at Luling High School was 625 students. In 2015, the enrollment grew to 650. By what percentage did the enrollment at Luling High School increase from 2014 to 2015?
Answer:
[tex]\%Increase = 4\%[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Population = 625[/tex]
[tex]Final\ Population = 650[/tex]
Required
Determine the percentage population increase
This is calculated using the following formula:
[tex]\%Increase = \frac{Final - Initial}{Initial} * 100\%[/tex]
[tex]\%Increase = \frac{650 - 625}{625} * 100\%[/tex]
[tex]\%Increase = \frac{25}{625} * 100\%[/tex]
[tex]\%Increase = \frac{25* 100\%}{625}[/tex]
[tex]\%Increase = \frac{2500\%}{625}[/tex]
[tex]\%Increase = 4\%[/tex]
Hence, there is a 4% increment from 2014 to 2015

Marcus and Jeremy both evaluated the expression −5^2 + 3. Marcus said the answer was −22. Jeremy said the answer was 28. Who is correct? Explain the error in the other student's work.
Marcus is wrong
This is because, Marcus calculated:
-5^2 + 3
= -25 + 3
= -22
This is wrong because it did not follow the rules which states that:
- × - = +
Jeremy calculation is shown below:
-5^2 + 3
-5 × -5 + 3

Find the slope and the y-intercept of the graph of y=6x-5.
Answer:
The slope is 6 and the y intercept is -5
Step-by-step explanation:
y=6x-5
The equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is 6 and the y intercept is -5
Answer:
[tex]slope=6\\\\y-intercept=-5[/tex]
Step-by-step explanation:
The given equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
where:
m is the slope (the change in the y values over the change in the x values)b is the y-intercept (where the x value is 0 and the line crosses over the y-axis)x and y are corresponding coordinate points that lie on the line (x,y)Find the values:
[tex]y=(slope)x+(y-intercept)\\\\y=6x-5[/tex]
6 is in the slope place, so the slope is 6.
5 is in the y-intercept place. Note how this number has a negative sign when the original equation says "+b". This means that the y-intercept is -5.

A local zoo has two large snakes. The anaconda is currently 5.23 meters long and grows 1.27 meters every month. The python is 4.76 meters long and grows 2.04 meters per month. How many months (m) does the zookeeper need to wait for the two snakes to be the same length?
Answer:
1 months
Step-by-step explanation:
Given
Anaconda
[tex]Length = 5.23m[/tex]
[tex]Growth = 1.27m[/tex] monthly
Python:
[tex]Length = 4.76m[/tex]
[tex]Growth = 2.04m[/tex] monthly
Required
Determine when their length will be equal
First, we need to write equations that determines the growth of each snake in m months.
For both snakes;
[tex]Expression = Length + Growth * m[/tex]
For the Anaconda, the expression is:
[tex]5.23 + 1.27 * m[/tex]
[tex]5.23 + 1.27 m[/tex] --- (1)
For the Python, the expression is
[tex]4.76 + 2.04 * m[/tex]
[tex]4.76 + 2.04m[/tex] ---- (2)
Both snakes will have equal length when both expressions (1 & 2) are equal
[tex]4.76 + 2.04m = 5.23 + 1.27 m[/tex]
Collect Like Terms
[tex]2.04m - 1.27 m= 5.23 - 4.76[/tex]
[tex]0.77 m= 0.47[/tex]
Solve for m
[tex]m = \frac{0.47}{0.77}[/tex]
[tex]m = 0.61[/tex]
[tex]m = 1[/tex] --- Approximated
Hence, the zookeeper will wait for 1 month

Answer:
102.6°F.Step-by-step explanation:
Aakash body temperature during the day = 99.2°F.
If by evening his body temperature increases by 3.4°F, then his body temperature in the evening will be expresses as the sum of his temperature in the day and the increment.
Temperature in the evening = 99.2°F+3.4°F.
Temperature in the evening = 102.6°F.
Hence his body temperature in the evening is 102.6°F.

When Adrian runs the 400 meter dash, his finishing times are normally distributed with a mean of 77 seconds and a standard deviation of 3 seconds. What is the probability that in a given race, his finishing time will be faster than 75 seconds, to the nearest thousandth?
Answer:
0.749
Step-by-step explanation:
We start by calculating the z-score
Mathematically:
z-score = (x-mean)/SD
z-score = (75-77)/3 = -2/3 = -0.67
The probability we want to calculate is;
P( X > -0.67)
we can use the standard normal distribution table for this
Using this table, the probability has a value 0.74857 which is 0.749 to the nearest thousandth

5:1
Step-by-step explanation:
The ratio 10: 2 will be equivalent to ratios 20:4, 30:6, 40:8, and 50:10. Then all the options are correct.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The equivalent is the expression that is in different forms but is equal to the same value.
The ratio is given below.
Ratio = 10 / 2
Multiply and divide the ratio by 2. Then we have
Ratio = 10 x 2 / 2 x 2
Ratio = 20 / 4
Multiply and divide the ratio by 3. Then we have
Ratio = 10 x 3 / 2 x 3
Ratio = 30 / 6
Multiply and divide the ratio by 4. Then we have
Ratio = 10 x 4 / 2 x 4
Ratio = 40 / 8
Multiply and divide the ratio by 5. Then we have
Ratio = 10 x 5 / 2 x 5
Ratio = 50 / 10
The ratio 10: 2 will be equivalent to ratios 20:4, 30:6, 40:8, and 50:10. Then all the options are correct.
