How do you write a log function?
A logarithmic function can be said to be an inverse function of exponents.
There are 2 kinds of logarithmic functions, natural lo and log with a base of 10.
The natural lo has an "e" as its base. This is an irrational number often used in Mathematics.
Here we write it as:-
ln a
where a refers to any number a. We generally don't mention anything for the base because it automatically implies that the base is e.
The second way is to write:-
logₓa,
here the "x" is the base while a is any number. Now logₓa will actually give us the exponent or the power of x that will give us a result of a. Here it is important to mention the value of the base.

50%
68%
95%
99.7%
Answer:
99.7%
Step-by-step explanation:
the standard deviation is 4 minuet but there is always outliers so thats why its not 100% of the time and the minutes are coverd by the deviation.
Answer:
68%
Step-by-step explanation:
The attached normal table shows area under the standard normal curve that are to the left of a particular z-score.
To find the area between two z-scores, say [tex]z_1 < z_2[/tex], find the area to the left of [tex]z_2[/tex] then subtract the area to the left of [tex]z_1[/tex]. That difference is the area between the two z-scores.
38 minutes has a z-score [tex]z_1=\frac{38-42}{4}=-1[/tex]
46 minutes has a z-score [tex]z_2\frac{46-42}{4}=1[/tex]
Find z= 1.0 in the table. The area in that row is .8413.
Find z=-1.0 in the table. The area in that row is .1587.
The difference, .8413 - .1587 = .6826 is the area under the normal curve between z=-1 and z=1.
.6826 is about 68%

The solution of the equation 3(2m - 1) ≤ 4m + 7 is option A m ≤ 5.
What are inequalities?A mathematical statement known as an inequality in algebra uses the inequality symbol to show the relationship between two expressions. An inequality symbol denotes that the expressions on each side are not equal.
The given inequality is 3(2m - 1) ≤ 4m + 7
Remove the brackets by multiplying 3 with each term inside it:
6m - 3 ≤ 4m + 7
Subtract 4m from both sides of the equation.
6m - 3 - 4m ≤ 4m + 7 - 4m
2m -3 ≤ 7
Add 3 to both sides of the equation.
2m - 3 + 3 ≤ 7 + 3
2m ≤ 10
Divide both sides of the equation with 2.
2m/2 ≤ 10/2
m ≤ 5
Hence the solution of the equation is m ≤ 5, that is option A.

Optimization A cone is made from a circular sheet of radium R by cutting out a sector and gluing the cut edges. What is the maximum volume of the cone
The cone should have its maximum volume. V=1/*3r2h is the formula for calculating the volume V of a cone with height h and radius r.
How do you find the maximum volume of a cone?The cone has a volume of
V=πr2h/3
Therefore, we must calculate the values of r and h in terms of R. R is the diameter of the cone's top-circular circle, and h is the cone's height.
R is the cone's slant height, and it serves as the hypotenuse of a right triangle.
R2 = h2 + r2, or r2 = R2-h2.
So V = (1/3)π
[R2-h2]
h = (π/3)[R2h-h3]
You must take the derivative of the cone's volume, set it to zero, then solve for h to determine the cone's maximum volume.
dV/dh=(π/3)[R2-3h2]
R2-3h2=0 --> h2=R2/3 -> h = R/√3
Now we can determine r:
r2=R2-R2/3 = (2/3)R2
The volume formula with r and h substituted:
V = (π/3)
r2h = (π/3)(2R2/3)
(R/√3)
V(R)=2πR3/(9√3)

Order the following number from greatet to leat. When entering fraction pleae ue "/". For example 1/2 or 3 2/3
-0. 44, -3/8, -0. 5, -2/5
The order from greatest to least is -3/8> -2/5>-0.44>-0.5
To compare all the numbers, we first convert the numbers to their fractional equivalent.
Therefore, -0.44= -44/100
And -0.5= -5/10
Now, we covert all the numbers to get the same denominator in all the numbers, therefore, let the denominator be 100
Therefore, we multiply -3/8 with 12.5 in both numerator and denominator to get, -37.5/100
Then, we multiply -2/5 with 20 in both numerator and denominator to get, -40/100
and, we multiply -5/10 with 10 in both numerator and denominator to get -50/100
Therefore, with these resultant value we can say that, -37.5/100> -40/100 >-44/100> -50/100
Thus, -3/8> -2/5>-0.44>-0.5

Using the centroid P on the triangle, the value of QN is 25.5 and PN is 8.5
What is Centroid of a TriangleThe centroid of a triangle is a point located at the intersection of the three medians (the lines that connect the vertices to the midpoints of the opposite sides). The centroid divides each median in two segments that have the same length. It is the center of gravity of the triangle and is the point at which the triangle's three medians intersect.
The centroid theorem states that the centroid of the triangle is at 2/3 of the distance from the vertex to the mid-point of the sides.
In this triangle, the centroid is at P and the QP is 17.
a) QN
The distance between QP is two-thirds the length of QN
The length of QP = 17
QP = 2/3 QN
17 = 2/3 QN
QN = (3 * 17) / 2
QN = 25.5
b) PN
The distance between PN is calculated as;
PN = QN - QP
PN = 25.5 - 17

Katie is correct. Any number that has 4 as a factor will also have 8 as a factor; therefore, any number that has 8 as a factor will have 4 as a factor.
Katie is correct. Since 4 is a factor of 8, any multiple of 8 will also be a multiple of 4.
Katie is incorrect. 80 is a number that has 8 as a factor but not 4.
Katie is incorrect; just because 4 is half of 8 does not mean that a number that has 8 as a factor will also have 4 as a factor. HELP PLS ASAP PLS AND THANK U
Katie is correct. Any number with 4 as a factor will also have 8 as a factor; therefore, any number with 8 as a factor will have 4 as a factor.
Katie is correct. Any number that is a multiple of 8 will also be a multiple of 4 because 8 is divisible by 4. For example, 8 is a multiple of 4 (8 = 2 x 4) and 16 is a multiple of 8 (16 = 2 x 8) and also a multiple of 4 (16 = 4 x 4). So, any number that is a multiple of 8 will also be a multiple of 4. So any number that is a multiple of 8 will also be a multiple of 4. Note that 80 is a multiple of 8, but not 4.

Rosa is 402 meters from a tall skyscraper in Chicago. Your line of sight to the top of the skyscraper is a 20 ° elevation angle to the ground. How tall is the skyscraper to the nearest decimal?
Answer:
900 meters
Step-by-step explanation:
If the height of the building (unknown) is opposite of the angle of elevation (20°) and the distance from the building (402 meters) is adjacent to the angle of elevation, then we use the tangent function to find the height of the building:
tanθ=opposite/adjacent
tan(20°)=x/402
402tan(20°)=x
900=x
Therefore, the height of the skyscraper is 900 meters.

What is the line x =- 4?
The line x= -4 is a vertical line passing through x-axis.
It is a distance of 4 units from the x-axis and is parallel to the y-axis.
Vertical Line in a coordinate plane refers to a line that is perpendicular to the Y-axis. From top to bottom and from bottom to top, it is a straight line. The x-coordinate of every point along this line will be the same. The points of vertical lines include, for instance, (2,0), (3,0), (-4,0), etc. Similar to this, a horizontal line is a line that runs parallel to the x-axis from left to right.
There is no slope to the vertical lines. It follows the y-axis parallel, hence the slope is not known. As a result, the equation for the vertical line that at any point, let's say 'a', crosses the x-axis is:

The length of ome material i 8. 3m correct to 1 decimal place. Write the error interval for the length ,x, of the material
The error interval for the length ,x, of the material is [8.25, 8.35)
We know that error interval is nothing but the limits of accuracy when a number has been rounded.
It is the range of possible values that a number could have been before a number was rounded.
Here, The length L of a some material is 8.3 meters.
The length of the material has been rounded to 8.3 to one decimal place.
The number below 8.3 is 8.2 and the number above is 8.4
Consider a half way between 8.2 and 8.3 for the lower bound and half way between 8.3 and 8.4 for the upper bound.
This means, the length of the material must have been between 8.25 meters and 8.35 meters to round to 8.3 meters to one decimal place.
Therefore, the required error interval would be 8.25 ≤ x < 8.35

If xx represents the number of tables sold and yy represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution. Inequality 1
Using the provided values and the conditions, The inequality equations required are : [tex]x+y \leq 20[/tex] and [tex]450x+200y \geq 4800[/tex].
What do you mean by equation?An equation is a mathematical statement in which two expressions are set equal to each other. It is typically written using an "=" sign, with the expressions on either side of the sign representing equivalent values. For example, the equation 2 + 2 = 4 states that the value of 2 plus 2 is equal to the value of 4. Equations can be used to express relationships and to solve problems.
What are inequalities?An inequality is a mathematical statement that compares two values or expressions. It is similar to an equation, but instead of using the "=" sign to indicate that the two sides are equal, it uses one of the following symbols: ">", "<", "≥", "≤" to indicate that the two sides are not equal. For example, the inequality 2 + 2 > 4 states that the value of 2 plus 2 is greater than 4. Similarly, the inequality 2 + 2 < 4 states that the value of 2 plus 2 is less than 4. Inequalities can be used to express constraints in a problem or to define a range of solutions. They can also be represented graphically by using a number line.
x= number of tables sold
y= number of chair sold
max furniture in a day = 20

Answer:
Slope of perpendicular line: 5
Slope of parallel line: -1/5
Step-by-step explanation:
Convert the equation to slope-intercept form (y=mx+b where m is the slope and b is the y-intercept)
x+5y=6
subtract x on both sides
5y=-x+6
divide by 5 on both sides
y=-(1/5)x+6/5
The slope of this equation is the coefficient of x, -1/5.
The slopes of two perpendicular lines are negative reciprocals of each other.
To get the negative reciprocal of a number, flip the numerator and denominator and multiply by -1.
-1/5 becomes 5, so that's the slope of a line perpendicular to our original line.
Parallel lines have the same slope, so that's just -1/5.
Slope of perpendicular line: 5
Slope of parallel line: -1/5
