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.

12.6 cups

Step-by-step explanation:

each liter has 4.2 cups so if you just multiply it by 3 you will get 12.6. cups.

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]

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

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

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:

[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

Answer:

Jeremy is correct

Step-by-step explanation:

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

= 25 + 3

= 28

The slope is 6 and the y intercept is -5

Step-by-step explanation:

y=6x-5

The equation is in slope intercept form

The given equation is written in slope-intercept form:

[tex]y=mx+b[/tex]

where:

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.

Answer:

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.

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.
