Which exponential equation is equivalent to the logarithmic equation below 4^c=256
The following logarithmic equation is equivalent to the given exponential equation,
[tex]log_{4}(256) = c[/tex]
Computing the Equivalent Logarithmic Equation
The given exponential equation is,
[tex](4)^{c} = 256[/tex]
As per the fundamental properties of exponentiation, the logarithmic equivalent equation of any exponential equation has the same base as that in the corresponding exponential equation. Exponentiation refers to the act of raising a number to the power of another number.
In the exponential equation, [tex](4)^{c} = 256[/tex], $ is the base. So, the base in its equivalent logarithmic equation will also be 4.
The result of the exponential expression becomes the operand for the log.
Terms in a Logarithmic Equation
For the logarithmic equation, [tex]log_{4}(256) = c[/tex],

4)8.0
Step-by-step explanation:
The trick is always to look at the number after the first decimal for rounding to 1 decimal place, if its above 5, you round it up to the next decimal; eg. 13.45 = 13.5 because the 5 will round it up,and if value below 5, you round it down; eg. 12.34 = 12.3 because the 4 is below 5 and the nearest 10th decimal is 3.

Triangle not drawn to scale
Given: measure of angle A = 51 degrees, b = 12, and c = 8. What is the length of a to the nearest tenth?
there are three brothers amir balu and caleb. Amirs age is half of calebs and balus age is 3/4 of calebs. In five years the sum of Amir's age and Balus age will be 16 more than Calebs age How old is each brother now.
The age of the brothers Caleb, Amir and Balu is 44 years, 22 years, and 33 years respectively.
What is Equation?An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.
Here, Let the age of the Caleb's be x years.
then age of Amir's be x/2 years.
also age of Balu's be 3x/4 years.
In 5 years,
Caleb's age = (x+5) years
Amir's age = (x/2 + 5) years
Balu's age = (3x/4 + 5) years
Now, According to question;
Amir's age + Balu's age = 16 + Caleb's age
(x/2 + 5) + (3x/4 +5) = 16 + (x + 5)
x/2 + 3x/4 - x = 16 + 5 - 5 - 5
(2x + 3x - 4x)/4 = 11
x/4 = 11
x = 4 X 11
x = 44
Now, Caleb's age = 44 years
Amir's age = 44/2 = 22 years
Balu's age = 3X44/4 = 33 years
Thus, the age of the brothers Caleb, Amir and Balu is 44 years, 22 years, and 33 years respectively.

The word expression is:
The cube of the sum of a number and 3.
The sum of a number x and 3 is:
x + 3
The cube of the number (x + 3)
= (x + 3)³
After expanding the cube of (a + b)
(a + b)³ = a³ + 3a²b + 3ab² + b³
Similarly,
(x + 3)³ = x³ + 3x²(3) + 3(x)(3)² + (3)³
(x + 3)³ = x³ + 9x² + 27x + 27
Thus, the word expression the cube of the sum of a number and 3 can be written as (x + 3)³ or x³ + 9x² + 27x + 27.

Answer:
y = 1/2 x -2
Step-by-step explanation:
rise/run from (-6, -5) to (-4, -4) = 1/2
(rise 1, run 2)
meaning that slope (m) = 1/2
we can now rewrite our points in y=mx + b formatting:
y = mx + b
-5 = (1/2)(-6) + b
-4 = (1/2)(-4)+b
now, let's solve for b
-5 = (1/2)(-6) + b
-5 = -3 + b
-2 = b
-4 = (1/2)(-4)+b
-4 = -2 + b
-2 = b
So, the equation for our line is y = [tex]\frac{1}{2}[/tex] x- 2

The following diagram represents all of the stages of a shrinking iceberg. The iceberg is circular, and when it started out, it had a radius of 100 feet. The iceberg shrank to a radius that was 75% of its original size every hour. Each circle in the drawing represents the size of the iceberg in each of the successive hours it was shrinking. Using this information, answer the questions having to do with the image:
a. Is this a geometric series or an arithmetic series? Explain why you chose this answer.
b. Describe the steps you would use to calculate the radius of the 6th circle.
c. Assuming this pattern continued forever, what would be the total length if you added all of the circles’ radii* together? Explain your answer.
A geometric progression is a sequence that involves a rate, causing a change in the subsequent values of the sequence with respect to the given rate.
The answers to the given question are as follows:
a. It is a geometric progression.
b. Radius of the 6th circle ≅ 23. 73 ft.
c. The total length, l, can be determined by: l = ∑0.75[tex]R_{i}[/tex], i = 1 to n.
Geometric progression involves a change in the subsequent values of a given sequence due to a rate. So considering the given question, the circular iceberg melts at a certain rate per hour. Thus its radius decreases at the given rate per hour.
a. Therefore it can be deduced that the question is on geometric progression.
b. To determine the radius of the 6th circle, the:
radius of the 1st circle = 100 ft
radius of the 2nd circle = 0.75 x 100
= 75 ft
radius of the t3rd circle = 0.75 x 75
= 56.25 ft
radius of the 4th circle = 0.75 x 56.25
= 42.1875 ft
radius of the 5th circle = 0.75 x 42.1875
= 31.640625 ft
radius of the 6th circle = 0.75 x 31.640625
= 23.73046875 ft
Thus the radius of the 6th circle is approximately 23. 73 ft.
c. Since the process is assumed to continue forever, let the number of hours required to be represented by n, and each radius of the iceberg be represented by R.
So then, we can say that the total length, l, of all the circles' radii is will be given by:
l = ∑0.75[tex]R_{i}[/tex], i = 1 to n

26) Jenny drove 48 mph for 65 minutes. Which is true? a. Jenny drove exactly 48 miles b. Jenny drove more than 48 miles c. Jenny drove less than 48 miles
Answer:
B- Jenny must have driven more than 48 miles.
Step-by-step explanation:
If Jenny rode for 60 at 48 mph, it would be exactly 48 miles. Though there is only 60 minutes in an hour, and Jenny rode 5 minutes longer than that, her drive being 65 minutes. To find how much she rode, 5 extra minutes into an hour would divide equally into 60, resulting in 12. Divide 48 by 12, and Jenny would have driven 4 miles in the 5 minutes drive after 60 minutes.
(Jenny basically driven 52 miles in 65 minutes).

Answer: 120
Step-by-step explanation:
The interior angle of the 12-sided polygon is
[tex]\frac{180(12-2)}{12}=150^{\circ}[/tex]
So, if we consider the triangle with angle x, two of its angles are each [tex]30^{\circ}[/tex] since they are supplementary to the interior angle of the 12-sided polygon.
Therefore, as angles in a triangle add to 180 degrees, x=120.
