The graph of y = tan x is concave up on the interval (0,π/2).
The graph of y = tan x is concave up on the interval (0,π/2). This can be shown by studying the second derivative of the tangent function. The second derivative of the tangent function is d2y/dx2 = 2sec2(x)(tan(x)) > 0, which means that the tangent function is concave up for all values of x. This implies that the graph of y = tan x is concave up on the interval (0,π/2). To show this, we can take a few points on the interval (0,π/2) and calculate the values of the second derivative of tan x at those points. For example, for x = π/4, the second derivative of tan x is 2sec2(π/4)(tan(π/4)) = 2(1.1547)(1.7321) = 4.9289 which is positive. This shows that the graph of y = tan x is concave up on the interval (0,π/2).

Find the average velocity for the position function s(t), in mm, over the interval 1 < t < 3, where t is in seconds. s(t) = 12t - t^2 s(t) = ln(t)
The required average velocity both conditions are -2 mm/s and -1/2 mm/s.
What is velocity?The direction of a body or object's movement is defined by its velocity. In its basic form, speed is a scalar quantity. In essence, velocity is a vector quantity. It is the speed at which distance changes. It is the displacement change rate.
According to question:To find the average velocity over the interval 1 < t < 3 for the position function s(t) = 12t - t^2, we need to find the derivative of the position function and then evaluate it at the limits of the interval. The derivative of the position function s(t) = 12t - t^2 is given by:
s'(t) = 12 - 2t
The average velocity over the interval 1 < t < 3 is given by:
v_avg = (s'(3) - s'(1)) / (3 - 1) = (12 - 23 - (12 - 21)) / (3 - 1) = -2
Therefore, the average velocity over the interval 1 < t < 3 for the position function s(t) = 12t - t^2 is -2 mm/s.
For the position function s(t) = ln(t), the derivative of the position function is given by:
s'(t) = 1/t
The average velocity over the interval 1 < t < 3 is given by:
v_avg = (s'(3) - s'(1)) / (3 - 1) = (1/3 - 1) / (3 - 1) = -1/2
Therefore, the average velocity over the interval 1 < t < 3 for the position function s(t) = ln(t) is -1/2 mm/s.

a boy weighs 88kg which is 10% higher than his normal weight. What is his normal weight.
If the boy weighs 88kg and it is 10% higher than his normal weight, we can use the following formula to find his normal weight:
Normal weight = Current weight / (1 + 10%)
10% of the boy's weight is 0.10 * 88kg = 8.8kg
So, Normal weight = 88kg / (1 + 8.8kg) = 88kg / 1.10 = 80kg
Therefore, the boy's normal weight is 80kg.

What is exponential distribution?The exponential distribution is a continuous probability distribution used in probability theory and statistics that frequently addresses the amount of time until a certain event occurs. It refers to a system in which things proceed continuously and separately at such an average speed that is constant.
Let X = The time (in minutes) that it takes a mechanic to change oil
We have,
X = Exp (mean = 20)
The distribution function of X is: F(x) = P (X < x) = 1 - e{-x/20}
a) Consider, P (X < 25) = F(25)
= 1 - e{-25/20}
= 0.7135
Consider, P( X > 15)
= 1 - P (X < 15)
= 1 - 1 - e{-15/20}
= 0.4724
Consider, P(15 < X < 25)
= P (X < 25) - P (X < 15)
= 1 - e{-25/20} - 1 - e{-15/20}
= 0.1859
Hence,
P(X<25) = 0.7135 P(X>15) = 0.4724 P(15<X<25)=0.1859
b) We want to find x such that P(X<x) =0.40

6) w(a)= a -1; Find w(0)
-1
Step-by-step explanation:Functions are often given in a different notation than other relationships. This is known as function notation.
Function Notation
Function notation is most commonly written with the variables f(x) and x. The variable f(x) is pronounced "f of x". Still, function notation can be written with any variables such as w(a) and a. The independent variable, also known as the y-value, is f(x). The dependent variable is x. For the question above, w(a) is independent and a is dependent. When solving a function for a specific value, to show what the x-value is, we put that value into the parentheses.
So, the question uses w(0) to show that 0 is the a-value we are using to solve. In context, w(0) means to solve the function when a = 0.
Solving for w(0)
To solve this, all we need to do is plug 0 in for a.
w(0) = 0 - 1w(0) = -1This means that w of 0 is equal to -1.

this was a question on my homework assignment from school but I don't know how to solve this without the height of the cone from top to bottom.
Answer: [tex]\sqrt{585}[/tex] units or [tex]3\sqrt{65}[/tex] units
Step-by-step explanation:
The formula for volume of a cone is π[tex]r^{2}[/tex][tex]\frac{h}{3}[/tex]. You can find the height by plugging in 72π for volume and 3 for radius.
diameter = radius x 2, so 6/2=3 units for radius.
72π = π([tex]3^{2}[/tex])([tex]\frac{h}{3}[/tex])
72=9*[tex]\frac{h}{3}[/tex]
8 = [tex]\frac{h}{3}[/tex]
h = 24 units
The formula for slant height is [tex]\sqrt{{r}^2 + {h}^2 }[/tex]
Plug in 3 for r and 24 for h. You should get [tex]\sqrt{(9+576)}[/tex]=[tex]\sqrt{585}[/tex] or 3[tex]\sqrt{65}[/tex] as your answer.

The Fahrenheit is 51.8
What is Celsius and Fahrenheit?Celsius also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water. Invented in 1742 by the Swedish astronomer Anders Celsuius, it is sometimes called the centigrde scale because of the 100° interval between the defined points.
Fahrenheit temperature scale based on 32° for the freezing point of water and 212° for the boiling point of water, the interval between the two being divided into 180 equal parts. The 18th-century German physicist Daniel Gabreil Fahrenheit originally took as the zero of his scale the temperature of an equal ice - salt mixture and selected the values of 30° and 90° for the freezing point of water and normal body temperature, respectively: these later were revised to 32° and 96°, but the final scale required an adjustment to 98.6° for the later value.
Conversion formula for °C to °F
°F = (9/5 × °C) + 32
Given:
Convert 11 °C to °F?
°F(11×1.8) + 32
= 19.8 + 32
= 51.8°F
Therefore 11 celsius (°c) is equal to 51.8 Fahrenheit (°F)

Line G has a slope of 5/4. Line H is perpendicular to line G, what is the slope of line g.
Answer:
-4/5
Step-by-step explanation:
Since Line H is perpendicular to Line G, its slope is the negative reciprocal of the slope of Line G.
Line G: m = 5/4
Line H: m = -4/5
A and B are oppoite vertice of a regular ix-ide hape, the point C and D are the midpoint of two oppoite ide. The area of the regular ix-ided hape i 60. Determine the product of the length of the line AB and CD!
The product of AB and CD in a regular hexagon with an area of 60 is (40 / √3) / 2.
To find the product of the length of AB and CD in a regular hexagon, we have to initially calculate the length of one side of the hexagon and later use that information to find the length of AB and CD.
Let us say that the length of one side of the hexagon = s.
W.k.t the area of the hexagon = 60, so we can use the formula for the area of a regular hexagon:
Area = (3 * √3) / 2 * [tex]s^2[/tex]
Making this equal to 60 and solving s:
60 = (3 * √3) / 2 * [tex]s^2[/tex]
120 = 3 * √3 * [tex]s^2[/tex]
40 = √3 * [tex]s^2[/tex]
(40 / √3) = [tex]s^2[/tex]
Taking the square root of both sides:
s = (40 / √3)^(1/2)
Now that we found the length of one side of the hexagon, So we can use that to find the length of AB and CD.
AB = the length of one side of the hexagon times the square root of 3, CD = the length of one side of the hexagon divided by 2.
So,
AB = s * √3
CD = s / 2
Now, we can find the product of AB and CD by multiplying them together:
AB * CD = s * √3 * s / 2
AB * CD = (s^2 * √3) / 2
AB * CD = (40 / √3) / 2
So the product of AB and CD in a regular hexagon with an area of 60 is equal to (40 / √3) / 2.

there are nine different positions on a baseball team. if a team has 15 players how many different line-ups can the team make? (assume every player can play every position.) the team can make different line-ups. baseball games consist of nine innings. a team wants to change its line-up every inning. if no game goes to extra innings, and a season consists of 66 games, how many complete seasons can the team play without repeating a line-up?
There are 18 seasons and the number of different line-ups the team can make is 24310
A) We are given the team has 17 players and there are 9 different positions in the team.
This is a combination question and thus, the number of different line-ups the team can make is;
C(17, 9) = 24310
B) We are told the basketball games consist of 9 innings.
Thus,
Number of games you can fill = 24310/9 = 2701.1111
And then we are told a season consists of 147 games.
Thus;
The number of complete seasons can the team play without repeating a line-up = 2701.1111/147 ≈ 18 seasons.
