The expanded form of the given logarithms ( log 4 s⁴ t) is =  2log(2) + 4log(s)  + log(t).

The features of the log are used to increase a single logarithm into numerous logarithms (or) compression multiple logarithms together into a single logarithm. A logarithm is simply another way of writing exponents. Thus, logarithm properties are obtained from exponent properties.

log (4 s⁴ t)

can be written as log (4 s⁴ t):

Property used in the solving (log b*c = log b  + log c) and (log ₐᵇ = b log a)

log (4 s⁴) + log( t)

log (4 ) + log(s⁴) + log( t)

Expand log (s⁴) by moving 4 outside the log.

log (4 ) + log(s) + log( t)

The expression also can be written as :

2log(2) + 4log(s)  + log(t)

The expanded form of the given logarithms ( log 4 s⁴ t) is =  2log(2) + 4log(s)  + log(t).

Using the bisection concept, it is found that the congruent angle to <GFH is given by:

d. <GFC.

A bisection of an angle is when a line splits an angle into two equal angles, that is, it splits by half the original angle.

The two resulting angles will be congruent, that is, they will have the same measure.

For this problem, we have that line CH bisects angle GFH, hence, from the explanation above, we have that:

Angles GFH and GFC are congruent, as due to the bisection, they both measure 90º.

Thus option D is correct, which is the one that lists angle GFC as congruent to angle GFH, that is, both angles having the same measure, which in this case is of 90º.

We have been given that -

scale = 1:75000.

we have to find out

(a) scale expressed as 1 cm represents n km.

Map scale refers to the ratio between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground

so 1,00,000 cm = 1 km.

(b) given -

distance between two towns on the map is 25 cm.

Find the actual distance, in kilometres, between the two towns.

Scale is given as 1:75000

for 25 cm distance = 25×75000 cm

                              = 18,75,000 cm

therefore 1875000 cm = 18.75 km.

the real distance between two points is 18.75 km.

(c) . The area of the lake in the real world is 3.5 square kilometers.

1 square kilometer is equal to 1 kilometers squared.

since 1 kilometer is equal to 100,000 centimeters, then 1 square kilometer is equal to 100,000^2 centimeters which is equal to 1 * 10^10 square centimeters.

3.5 square kilometers on the map is therefore equal to 3.5 * 10^10 square centimeters.

1 centimeter on the map is equal to 75000 centimeters in the real world.

1 square centimeter on the map is equal to 75000^2 centimeters in the real world which is equal to5625 * 10^6 square centimeters in the real world.

take 3.5 * 10^10 square centimeters in the real world and divide it by 5625 * 10^6 square centimeters and you get .0006 * 10^4 square centimeters which is equal to 6 square centimeters on the map.

When the company asked its customers to describe how satisfied they were with the latest product, it's a discrete data.

It should be noted that the main distinction between continuous and discrete data is that the former has a finite value that can be counted while the latter has an endless number of possible values that can be measured.

A count involving integers is referred to as discrete data because there are a finite number of possible values. This kind of data cannot be separated into separate components. Discrete data consists of discrete variables that are non-negative, countable, and finite.

In this case, it should be noted that the measurement was taken based on their satisfaction. Therefore, it's a discrete variable.

The figure must be true if Ray CE seems to be the angle bisector of ZACD, as stated in the supplied statement.

∠ACE = ∠DCB.

The line or line segment that divides an angle into two equal halves is known as the (interior) bisector of the an angle.

A bisector is a tool that divides an angle equally into two equal halves. Divide the number of degrees in the angle by two to determine the angle bisector.

If the angle bisector of ADC is the ray CE

then,

Angle ACD = ACE + ECD

ACE = ECD

So,

ACD = 2(ACE)

ACE = 1/2 (ACD)

The solution for the value of x for the Logarithmic expression 2㏑x + 3㏑2 = 5 is

4.30716.

A logarithmic equation is one that includes the logarithm of a variable-containing expression. To address exponential equations, first determine whether both sides of the equation can be written as powers of the exact number.

Some properties of ㏑ function are-

Now, as per the given expression;

2㏑x + 3㏑2 = 5

Use the Power Rule: n㏑A = ㏑Aⁿ

㏑x² + ㏑2³ = 5

Now, apply the Product Rule : ㏑A + ㏑B = ㏑(AB)

㏑(x² ×2³) = 5

㏑(x² ×8) = 5

Raise the formation to exponential form, using e as the base.

e∧㏑(x² ×8) = e⁵

Comparing the base of both sides;

x² ×8 = 5

x² = 5/8

x = ±√5/8

x = ±4.30716

Due to domain restrictions, the argument of any logarithm is always positive & greater than zero.

Answer:

In plane Euclidean geometry, a rhombus is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal

Step-by-step explanation:

The equation of the line that passes through  ​(-3​,2​), and is perpendicular to 3x - 5y = -2 is:

y - 2 = -5/3(x + 3), or

y = -5/3x - 3

The equations of two lines that are perpendicular to each other will always have a slope (m) that are negative reciprocals to each other.

Thus, given the equation of a line as, 3x - 5y = -2, rewrite in slope-intercept form (y = mx + b) to easily determine its slope (m):

3x - 5y = -2

- 5y = -3x - 2

y = 3/5x + 2/5

The slope (m) = 3/5.

The negative reciprocal of 3/5 is -5/3.

Hence, the slope (m) of the line that is perpendicular to 3x - 5y = -2 would be -5/3.

Substitute (a, b) = (-3, 2) and m = -5/3 into y - b = m(x - a):

y - 2 = -5/3(x - (-3))

y - 2 = -5/3(x + 3) [point-slope form]

Rewrite the equation in slope-intercept form:

y - 2 = -5/3(x + 3)

y - 2 = -5/3x - 5

y = -5/3x - 5 + 2

y = -5/3x - 3 [slope-intercept form]

In summary, the equation of the line that passes through  ​(-3​,2​), and is perpendicular to 3x - 5y = -2 is:

y - 2 = -5/3(x + 3) [point-slope form], or

y = -5/3x - 3 [slope-intercept form].

Step-by-step explanation:

The value of x will be 12 and the angle measurements of ∠A and ∠B is 45°.

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.

Given is a set of two lines parallel to each other intersected by a line. From the question, we can write -

∠A = 5x - 15

∠B = 2x + 21

Refer to the image attached.

From the figure it can be seen that -

∠B = ∠TRO = 2x + 21             [Vertically opposite angles are equal]

∠TRO = ∠POR = 2x + 21       [Alternate interior angles are equal]

∠A = ∠POR = 2x + 21            [Vertically opposite angles are equal]

It is given that

∠A = ∠B

5x - 15 = 2x + 21

3x = 21 + 15

3x = 36

x = 12

Then -

∠A = 2x + 21 = 24 + 21 = 45°

∠B = ∠A = 45°

Therefore, the value of x will be 12 and the angle measurements of ∠A and ∠B is 45°

A logarithmic form is a method to write equations when solving for a variable in an exponent. Any exponential equation can be written as a logarithm. The logarithmic form is used to calculate an exponent of an equation.

The logarithmic form is a rearrangement of the exponential form.

Exponential form: aᵇ = c

Logarithmic form: logₐ c = b

Comparing this with our equation, a=x, b=4, c=y
