Step-by-step explanation:
•Once you get familiar with the lesson you understand it in a much easier way by doing problems pretty often
•If you want get more comfortable with it just search for a few questions in internet specifically educational platforms in schools like teachers
•But if your still confused you can always study it for free by byjus or vedantu and the best option in my opinion is ask your teacher to explain it once more
•It is very hard to solve questions if you are not freindly with the chapter
• Do not hesitate to ask questions if your doubting or anything you might face problems in higher grades with the topic

Condense to a single logarithm: ln x +ln y − z
Question 12 options:
A) ln (x + y – z )
B) ln xy∕z
C) (ln x)(ln y∕z)
D) ln xy∕ ln z
Answer:
It is B
Step-by-step explanation:
[tex] ln(x) + ln(y) - ln(z) [/tex]
from law of logarithms:
[tex]{ \bf{ ln(a) + ln(b) = ln(ab) }} \\ and \\ { \bf{ ln(a) - ln(b) = ln( \frac{a}{b} ) }}[/tex]
so, in the question:
[tex] ln(x) + ln(y) - ln(z) \\ \\ = \{ ln(xy) - ln(z) \} \\ \\ = ln( \frac{xy}{z} ) [/tex]
The required logarithmic expression is ln(xy/z). Option B is correct.
Given that
To simplify ln x + ln y + ln z
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
A logarithmic function can be defined as the function inverse of the exponential function is a logarithmic function.
In the question, an algebraic expression of the log function is given a simplified form of the expression to be determined using the logarithmic property.
Simplification,
= ln x +ln y + ln z
Since log A + log B = log(A.B)
and log A - logB = log(A/B)
From above properties
= ln (x . y) - ln z
= ln [(x. y )/z]
Thus, the required logarithmic expression is ln(xy/z). Option B is correct.

A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 21. Find the number
Answer:
The number is 5
Step-by-step explanation:

8x + 2
8x + 2 = 42 Subtract 2 from both sides
- 2 -2
8x = 40 Divide by 8

The longest side of an acute isosceles triangle is 12 centimeters. Rounded to the nearest tenth, what is the smallest possible length of one of the two congruent sides?
6.0 cm
6.1 cm
8.4 cm
8.5 cm
Answer:
6.1 cm
Step-by-step explanation:
it depends on what your teacher told you and wants to see.
because, theoretically, it would be 6.0 cm. but that would render the whole triangle into a flat line, as the 2 equal sides together (2×6 = 12) would be exactly as long as the baseline (12) of the triangle.
which is again a theoretically possible construct (counting as extreme triangle).
but it is more likely that your teacher wants the definition applied that for each combination of 2 sides this combination has to be larger (and not larger or equal) than the third side.
so, the 2 equal sides have to be larger than 6 cm.
the smallest number in your answer options to fit that criteria is 6.1 cm
just FYI - your teacher was not very precise in the phrasing, because there are many numbers smaller than 6.1 that would still be correct.
like 6.01, or 6.005, ...
Rounded to the nearest tenth, the smallest possible length is 6.1 cm.Thus, the answer is B) 6.1 cm.
In an acute isosceles triangle, the longest side is opposite the largest angle. Since the triangle is isosceles, the two congruent sides are equal in length.
In an acute triangle, the largest angle is less than 90 degrees. In an isosceles triangle, the two base angles are congruent. Therefore, each base angle must be less than 45 degrees.
Now, let's apply the triangle inequality theorem to determine the smallest possible length of one of the congruent sides. According to the theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, the longest side is 12 centimeters. Let's assume each of the congruent sides has a length of x centimeters.
Based on the triangle inequality theorem, we have the following inequality:
2x > 12
To find the smallest possible length, we divide both sides of the inequality by 2:
x > 6
Therefore, the smallest possible length of one of the two congruent sides is greater than 6 centimeters.
Rounded to the nearest tenth, the smallest possible length is 6.1 cm.
Thus, the answer is B) 6.1 cm.

. Describe a process you would use to create the perpendicular bisector to a segment AB using
only an unmarked straightedge and an unmarked compass.
WILL MARK BRAINIEST!!!
The perpendicular bisector on a line segment AB is in the attached image.
Given:
Segment ABTo Construct:
The perpendicular bisector to segment AB.Solution:
A segment is a line with two ends with a specific length.
A perpendicular bisector is a line intersecting the other line segment into two equal lengtsh at an angle of 90 degrees.
Steps of construction:
With help of unmarked straightedge draw segment,AB.Open the compass more than half of the length of the AB segment and from point A, draw an arc above and below AB.Now, with that same compass from B draw arcs cutting the previous arcs made above and below the AB label them C and D.Draw a straight line from C to D which will be the perpendiular bisector of segemnt AB.The perpendicular bisector to a segment AB is in the image attached.

https://brainly.in/question/3957?tbs_match=3
#learnwithbrainly
Answer:
Step-by-step explanation:
To create a perpendicular bisector, you need a compass, a straightedge, and a pencil. As well as the line segment AB drew down.
1> You start by opening the compass and stretching it to a width greater than half the length of AB.
2> Then you simply place one point of the compass on the line segments A. From here, you move the compass and draw arcs above and below the line AB.
3> Without moving the compass measure, remove it from point A and place it onto point B. You basically repeat step 2 by drawing arcs above and below the line again.
4> If you've done it right, the arcs should be in the middle, X and Y, and using a straightedge/ruler you draw a line that goes vertically through where they connect.
and that should be your perpendicular bisector using segment AB.
