The value of the expression log₅62 by using the change of base theorem is 2.5644.
Given that the expression is log₅62.
We are required to find the value of the expression by using the change of base formula.
The change of base formula is basically used to find the base of the log value is different from 10. It says that [tex]log_{a}b[/tex]=log b/log a.
Expression is log₅62.
log₅62=log 62/log 5
Now we have to use the value of log 62=1.7923 and log 5=0.6989 in the above expression.
=1.7923/0.6989
=2.5644
Hence the value of the expression log₅62 is 2.5644.

Simplify. 3√63 +√28
The value of the expression 3√63 +√28 is 5√7 or 13.228.
A number is a fundamental mathematical unit. For counting, measuring, and comparing quantities, we utilize numbers. A set of symbols, or numerals, used to represent numbers is known as a number system.
A square root is a factor of a number that yields the original number when multiplied by itself.
Consider the expression 3√63 +√28,
Let's assume x = 3√63 +√28
Now,
63 = 3 × 21 = 3 × 3 × 7
28 = 2 × 14 = 2 × 2 × 7
Therefore,
x = 3√63 +√28
x = √ [ 3 × 3 × 7 ] + √ [ 2 × 2 × 7 ]
x = ( √ 3² ) × ( √7 ) + ( √2² ) × √7
x = 3√7 + 2√7
x = ( √7 ) × [ 3 + 2 ]
x = ( √7 ) × 5
x = 5√7
x = 5 × 2.6457
x = 13.228
Hence, the value of 3√63 +√28 is equal to 13.228.

Answer:
1.: 4 songs
2.: 65 dollars
3.: 4 cookies
4.: 53 cards
5.: 14 degrees
Step-by-step explanation:
1.: Split 40 songs evenly between 10 days. 40 divided by 10 equals 4.
2.: 160, the needed amount, minus 95, the amount already had, equals 65. 95+65=160.
3.: Split 32 cookies evenly between 8 people. 32 divided by 8 is 4.
4.: 200-147=53, so 147+53=200.

Consider the system of linear
equations below. Choose nonzero values for a, b.
and c so the system satisfies the given condition.
Explain your reasoning.
x+y+z=2
ax + by + cz= 10
X- 2y+z=4
a. The system has no solution.
b. The system has exactly one solution.
c. The system has infinitely many solutions.
For no solutions, put a = b = c = -1, for exactly one solution, put a = 1 and b = c = 0 and for infinite solutions, put a = b = c = 5 in the system of linear equations.
We have the system of equations:
x + y + z = 2 …(1)
a x + b y + c z = 10 …(2)
x - 2 y + z = 4 …(3)
a. The system has no solution.
Put a = b = c = -1 in (2)
We get:
- x - y - z = 10
Now add (1) and (2)
0 = 12
which is not possible.
So, no solution.
b. The system has exactly one solution.
a = 1 and b = c = 0
We have the equations as:
x + y + z = 2 …(1)
x = 10 …(2)
x - 2 y + z = 4 …(3)
c. The system has infinitely many solutions.
a = b = c = 5
We will have the equations:
x + y + z = 2 …(1)
5 x + 5 y + 5 z = 10 …(2)
x - 2 y + z = 4 …(3)
Therefore, we get that, for no solutions, put a = b = c = -1, for exactly one solution, put a = 1 and b = c = 0 and for infinite solutions, put a = b = c = 5 in the system of linear equations.

what is the equation in slope intercept form of the line that passes throught the points (-4, 2) and (12, 6)
The equation in slope intercept form of the line that passes through the points (-4, 2) and (12, 6) is y = 0.25x + 3
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the equation of the line?The points are given as
(-4, 2) and (12, 6)
Calculate the slope of the points using
m = (y2 - y1)/(x2 - x1)
So, we have
m = (6 - 2)/(12 + 4)
Evaluate
m = 0.25
The equation is then calculated as
y = m(x - x1) + y1
Where
(x1, y1) = (-4, 2)
So, we have
y = 0.25(x + 4) + 2
Expand
y = 0.25x + 1 + 2
Evaluate
y = 0.25x + 3
Hence, the equation in slope intercept form of the line that passes through the points (-4, 2) and (12, 6) is y = 0.25x + 3

What is termed as the mass energy equivalence?An equation deduced from Einstein's Special Theory of Relativity that expresses the correlation between the mass & energy of mass objects.
Some key features related to the mass energy equivalence are-
E = mc², where E is the object's energy in joules, m is its relativistic mass in kilograms, & c is the speed of light (approximately 3 X 10⁸ meters per second). The concept of mass-energy equivalence states that the total mass of a system can change while the total & total momentum stay unchanged; for instance, the collision of an electron & a proton shatters the mass of both particles while producing energy in the form of photons. The discovery of mass-energy equivalence was critical in developing a theory of atomic fission and fusion reactions.As per the given question, the expression is;
=> e = m c²
=> c² = e/m
Now, taking square root of both sides.

-5x-3y+5z=23
Using Gaussian elimination, the solution to the given system of equations is:
x = 5, y = -11, z = 3.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
The system is composed by these following equations:
2x - y + 4z = 33.x + 2y - 3z = -26.-5x - 3y + 5z = 23.For Gaussian elimination, the first step is building the augmented matrix of the system, for which which:
The first three columns are composed by the coefficients of x, y and z, respectively.The last column is composed by the results of the operations.Hence the augmented matrix of the system is:
[tex]\left[\begin{array}{cccc}2&-1&4&33\\1&2&-3&-26\\-5&-3&5&23\end{array}\right][/tex]
Then, we need to make the coefficient of x zero in the second and third rows, which is a step to find the solution in an easier way, hence these following row operations are applied:
R2 -> 2R2 - R1.R3 -> 5R1 + 2R3.Then:
[tex]\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&-11&30&211\end{array}\right][/tex]
Now we need to make the coefficient of y on the third row zero, which will make it possible for us to solve for z hence the following row operation is applied:
R3 -> 11R2 + 5R3.
Then:
[tex]\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&0&40&120\end{array}\right][/tex]
Starting at the third row and moving up, we have that:
40z = 120 -> z = 3.5y - 10z = -85 -> y = -11.2x - y + 4z = 33 -> x = 5.Hence the solution to the given system of equations is:
x = 5, y = -11, z = 3.

If each unit on the map's grid represents 30 meters and Kampp 150 is in Dra Abul Naga, which is about 1,900 meters east and 250 meters south of distance from Tutankhamen's tomb,then we have to add approximately 64 units to the x axis to include Dra Abul Naga.
Given that each unit on the map's grid represents 30 meters and Kampp 150 is in Dra Abul Naga, which is about 1,900 meters east and 250 meters south of Tutankhamen's tomb.
We are required to find the number of units to be added to x axis that are needed to include Dra Abul Naga.
1 unit=30 meters
Distance in east lie on x axis=1900
Number of units to be added on x axis=1900/30
=63.33
It is equal to 64 units approximately.
Hence if each unit on the map grid represents 30 meters and Kampp 150 is in Dra Abul Naga, which is about 1,900 meters east and 250 meters south of Tutankhamen's tomb,then we have to add approximately 64 units to the x axis to include Dra Abul Naga.

A single unit on the map;'s grid represents 30 meters.
Kampp 150 in Dra Abul is 1900 meters east and 250 meters south of Tutankhamun's tomb.
The distance in the east or x-axis is 1900 meters.
Therefore, the number of units to be added to the x-axis will be:
= 1900 meter ÷ 30 meters
= 63.33 units
Similarly, the distance on the y-axis is 250 meters.
Therefore, the number of units that are needed to be added will be:
= 250 meter / 30 meters

If Amal can maintain that pace, how long will it take him to run 1 mile?
The time it would take Amal to run 1 mile if he maintains the pace is 12 minutes
From the question, we are to determine how long it would take Amal to run 1 mile
From the given information,
Amal can run 1\8 mile in 1 1\2 minutes.
First, we will calculate Amal's speed
Using the formula,
Speed = Distance/ Time
Then,
Amal's speed = 1/8 ÷ 1 1/2
Amal's speed = 1/8 ÷ 3/2
Amal's speed = 1/8 × 2/3
Amal's speed =1/12 miles/minute
Now, we will determine how long it would take him to run 1 mile
Time = Distance/ Speed
Time = 1 ÷ 1/12
Time = 1 × 12/1
Time = 12 minutes
Hence, the time it would take Amal to run 1 mile if he maintains the pace is 12 minutes
