Use the Quotient Rule of Logarithms to write an expanded expression equivalent to ln(2/7).Make sure to use parenthesis
around your logarithm functions log(x + y).
Provide your answer below:
Answer:
ln(2) - ln(7)
Step-by-step explanation:
Logarithmic expressions are represented using ln or log keywords
The expanded expression of ln(2/7) is [tex]\mathbf{ln(2) - ln(7)}[/tex]
The expression is given as:
[tex]\mathbf{ln(2/7)}[/tex]
The quotient rule of logarithm states that:
[tex]\mathbf{ln(a/b) = ln(a) - ln(b)}[/tex]
So, by comparison:
a = 2, and b = 7
So, we have:
[tex]\mathbf{ln(2/7) = ln(2) - ln(7)}[/tex]
Hence, the expanded expression of ln(2/7) is [tex]\mathbf{ln(2) - ln(7)}[/tex]

An engineer estimated the weight of a steel beam to be 150 pounds. The actual weight of the beam was 143 pounds.
Find the absolute error and the percent error of the engineer's estimate. If necessary, round your answers to the nearest tenth.
absolute error = ? (pounds)
percent error = ? (%)
Answer:
absolute error: 7 pounds
percent error:4.9%
Step-by-step explanation:
Absolute error:
150-143=7 pounds
Percent error:
=l[tex]\frac{150-143}{143}[/tex] l x 100
=l[tex]\frac{7}{143}[/tex]l x 100
=0.04895x100

Los ángulos de elevación hacia un
avión se miden desde la parte superior y la base de
un edificio que tiene 20 m de altura. El ángulo desde
la azotea es de 38°, y desde la base es de 40°.
Calcule la altitud del avión
A partir del diagrama geométrico y las relaciones trigonométricas, la altitud del avión con respecto al suelo es aproximadamente 290.276 metros.
¿Cómo hallar la altitud del avión con respecto al suelo?
A partir del enunciado se construye un sistema geométrico formado por el triángulo obtusángulo. Con base en la información disponible, se determina las longitudes faltantes del triángulo:
[tex]\frac{20\,m}{\sin 2^{\circ}} = \frac{r_{1}}{\sin 128^{\circ}} = \frac{r_{2}}{\sin 50^{\circ}}[/tex] (1)
Los lados faltantes son r₁ ≈ 451.589 m and r₂ ≈ 439 m. Finalmente, la altitud del avión se obtiene mediante la siguiente relación trigonométrica:
h = r₁ · sin 40° (2)
h = (451.589 m) · sin 40°
h ≈ 290.276 m
A partir del diagrama geométrico y las relaciones trigonométricas, la altitud del avión con respecto al suelo es aproximadamente 290.276 metros.

unit 7 lessen 12 cool down 12.5 octagonal box a box is shaped like an octagonal prism here is what the basee of the prism looks like
for each question, make sure to include the unit with your answers and explain or show your reasoning
To construct an octagonal box, you will need to cut eight rectangular pieces of equal size and eight regular octagons with equal sides. After cutting the pieces, fold them in a way that forms the octagonal box.
In an octagonal box shaped like an octagonal prism, the base is an octagon. Since the question does not provide specific measurements or angles for the octagon, we will assume that all the sides and angles of the octagon are equal. Let's denote the length of each side of the octagon as "s."
Area of the octagon = 2(1 + √2) * s^2
Where s is the length of each side.
An octagonal box is a type of prism that has eight equal sides and is shaped like a polygon. It has 8 vertices, 12 edges, and 6 faces.
The top and bottom faces are regular octagons, while the remaining faces are rectangles that connect the sides of the octagons.
Octagonal boxes can be used for various purposes, including storage, decoration, and shipping.
They are durable and can protect the contents inside from damage. In unit 7 lesson 12 cool down 12.5, you might be required to construct an octagonal box.

Please calculate the probability using the following equations (in document)
Substitute u = t ³/2592 and du = t ²/864 dt. Then
[tex]P(T)=1-\displaystyle\int_0^T f(t)\,\mathrm dt=1-\displaystyle864\left(1.1574\times10^{-3}\right)\int_0^{\frac{T^3}{2592}}e^{-u}\,\mathrm du[/tex]
The probability that a 12 hour surgery is successful is P (12), so letting T = 12 gives

For the polynomial below, 3 is a zero.
g(x)=x^3-7x^2+9x+9
Express g(x) as a product of linear factors
9514 1404 393
Answer:
g(x) = (x -3)(x -2+√7)(x -2 -√7)
Step-by-step explanation:
Synthetic division can tell us the quadratic factor that remains when the factor (x-3) is divided out.
g(x) = (x -3)(x^2 -4x -3)
The quadratic is not factorable over integers. Its vertex form is ...
(x -2)^2 -7
so its roots are x = 2±√7.
That means the linear factorization of g(x) is ...
g(x) = (x -3)(x -2-√7)(x -2+√7)
_____
I find it easy to learn the vertex form of the quadratic factor by using a graphing calculator to show the graph of the quadratic.

which fraction is the least 2/4, 5/10, 2/5, 3/4
Answer:
2/5 or the third one
Step-by-step explanation:
The first two are 1/2 after they are simplified and the second two are just below or just above one half, the last one is above and the third one is below.
Answer:
2/5
Step-by-step explanation:
Convert all fractions to have a common denominator
4, 10, and 5 can all be multiplied to equal 20
As a result, we will use 20 for the common denominator
What multiplied by 4 equals 20? 5 × 4 = 20
What multiplied by 10 equals 20? 2 × 10 = 20
What multiplied by 5 equals 20? 4 × 5 = 20
If we multiply this to the denominator, we must also multiply the same number to the numerator
Starting from left to right:
2 × 5 / 4 × 5 = 10/20
5 × 2 / 10 × 2 = 10/20
2 × 4 / 5 × 4 = 8/20
3 × 5 / 4 × 5 = 15/20
Compare: 10/20, 10/20, 8/20, 15/20
Which fraction has the smallest numerator?
8/20 as 8 is less than 15 and 10
Which fraction was 8/20? Check back to our work.
8/20 = 2/5
2/5 is the least

Answer:
The machinery ages three years for every $10,000 loss in value.
Step-by-step explanation:
We can see from the graph that each year, the machinery loses a value of $5,000 (Goes from $50,000 to $45,000 after year one, from $45,000 to $40,000 after year two etc). So we can discount the last two answers.
If it loses $5,000 each year, it loses $15,00 after ageing three years, and $25,00 after five years. Though neither of the first two answers correspond to this, the first answer is closest.
