Answer:
No
Step-by-step explanation:
In exponential behavior each number increases by some some power in respect of previous number.
example
2,4,8,16
which is similar as 2 , 2^2,2^3,2^4
here it can be represented as y = 2^x
here we see that each number increases by power of 2, hence it shows exponential behavior.
____________________________________________
In the problem
(1,1), (2,2) ,(3,3), (4,4)
23 see that each number increases by one unit in respect of previous number
and also x is same as y
thus, it can be represented as
y = x which is linear behavior
hence , the given data set shows linear behavior rather than exponential behavior.

The amount Q of water emptied by a pipe varies directly as the square of the diameter d. A pipe 5 inches in diameter will empty 50 gal of water over a fixed time period.
Assuming the same kind of flow, how many gallons of water are emptied in the same amount of time by a pipe that is 2 inches in diameter?
gallons are emptied.
Answers
Answer:
Q= 8
The amount emptied is 8 gallons of water
Step-by-step explanation:
First we need to create the equation for the above statement.
Q is directly proportional to the square of d
Q= kd²
Q= 50
d= 5
50= k5²
50 = k25
K = 50/25
K = 2
K is the constant of proportionality.
Now our equation is
Q= 2d²
Where Q = volume in gallons
d = pipe diameters in inch
For a pipe of diameter 2 inch
The amount of gallons of water emptied assuming the same kinf of flow is
Q= 2d²
Q= 2(2)²
Q= 2(4)
Q= 8
The amount emptied is 8 gallons of water

Help me! Sorry for the other question.... let’s try it again! 1/2 x + 3/5 x = 5/4
Answers
Answer:
x = 1 3/22
Step-by-step explanation:
1/2 x + 3/5 x = 5/4
We need to get rid of the fractions by multiplying by 20 on each side
20 (1/2 x + 3/5 x) = 20 * 5/4
Distribute
10x + 12x = 25
Combine like terms
22x = 25
Divide each side by 22
22x/22 = 25/22
x = 22/22 + 3/22
x = 1 3/22
Answer:
[tex]x = 1\frac{3}{22}[/tex]
Step-by-step explanation:
=> [tex]\frac{1}{2} x + \frac{3}{5} x = \frac{5}{4}[/tex]
LCM = 20
So, Multiplying both sides by 20
=> [tex]20 (\frac{x}{2} + \frac{3x}{5}) = 5 * 5[/tex]
[tex]10 * x + 4*3x = 25\\10x+12x = 25\\22x = 25[/tex]
Dividing both sides by 22
[tex]x = \frac{25}{22}[/tex]
[tex]x = 1\frac{3}{22}[/tex]

Betty has several of the standard six-sided dice that are common in many board games. If Betty rolls one of these dice, what is the probability that: She rolls a three. She rolls an odd number. She rolls a six or odd number.
Answers
Answer:
The probability of rolling a 3 is 1/6 because there's only one 3 out of the 6 options that are on a standard die.
The probability of rolling an odd number is 3/6 or 1/2 because 3 out of the 6 numbers on a standard die (1, 3, 5) are odd.
The probability of rolling a six or odd number is 4/6 or 2/3 because out of the 6 numbers on a standard die, there's one 6 and 3 odd numbers and 1 + 3 = 4.
Suppose that the duration of a particular type of criminal trial is known to be normally distributed with a mean of 22 days and a standard deviation of 6 days. 72% of all of these types of trials are completed within how many days
Answers
Answer:
25.5 days
Step-by-step explanation:
Mean number of days (μ) = 22 days
Standard deviation (σ) = 6 days
Z-score for the 72nd percentile (according to tabulated values) = 0.583
The z-score for any number of days, X, is determined by:
[tex]z=\frac{X-\mu}{\sigma}[/tex]
The value of X that is greater than 72% of the trial times is:
[tex]0.583=\frac{X-22}{6}\\ X=25.5\ days[/tex]
Therefore, 72% of all of these types of trials are completed within 25.5 days.

A car is being driven, in a straight line and at a uniform speed, towards the base of a vertical tower. The top of the tower is observed from the car and, in the process, it takes 10 min for the angle of elevation to change from 45° to 60°. After how much more time will this car reach the base of the tower? Options: a. 5( √3+ 1 ) b. 6 (√3 +√2) c. 7 (√3- 1) d. 8 (√3-2)
Answers
Answer:
The correct answer is option a.
a. 5( √3+ 1 )
Step-by-step explanation:
Given that the angle changes from 45° to 60° in 10 minutes.
This situation can be represented as right angled triangles [tex]\triangle[/tex]ABC (in the starting when angle is 45°)and [tex]\triangle[/tex]ABD (after 10 minutes when the angle is 60°).
AB is the tower (A be its top and B be its base).
Now, we need to find the time to be taken to cover the distance D to B.
First of all, let us consider [tex]\triangle[/tex]ABC.
Using tangent property:
[tex]tan\theta =\dfrac{Perpendicular}{Base}\\\Rightarrow tan 45=\dfrac{AB}{BC}\\\Rightarrow 1=\dfrac{h}{BC}\\\Rightarrow h = BC[/tex]
Using tangent property in [tex]\triangle[/tex]ABD:
[tex]\Rightarrow tan 60=\dfrac{AB}{BD}\\\Rightarrow \sqrt3=\dfrac{h}{BD}\\\Rightarrow BD = \dfrac{h}{ \sqrt3}\ units[/tex]
Now distance traveled in 10 minutes, CD = BC - BD
[tex]\Rightarrow h - \dfrac{h}{\sqrt3}\\\Rightarrow \dfrac{(\sqrt3-1)h}{\sqrt3}[/tex]
[tex]Speed =\dfrac{Distance }{Time}[/tex]
[tex]\Rightarrow \dfrac{(\sqrt3-1)h}{10\sqrt3}[/tex]
Now, we can say that more distance to be traveled to reach the base of tower is BD i.e. '[tex]\bold{\dfrac{h}{\sqrt3}}[/tex]'
So, more time required = Distance left divided by Speed
[tex]\Rightarrow \dfrac{\dfrac{h}{\sqrt3}}{\dfrac{(\sqrt3-1)h}{10\sqrt3}}\\\Rightarrow \dfrac{h\times 10\sqrt3}{\sqrt3(\sqrt3-1)h}\\\Rightarrow \dfrac{10 (\sqrt3+1)}{(\sqrt3-1)(\sqrt3+1)} (\text{Rationalizing the denominator})\\\Rightarrow \dfrac{10 (\sqrt3+1)}{3-1}\\\Rightarrow \dfrac{10 (\sqrt3+1)}{2}\\\Rightarrow 5(\sqrt3+1)}[/tex]
So, The correct answer is option a.

A tank contains 80 kg of salt and 1000 L of water. A solution of a concentration 0.04 kg of salt per liter enters a tank at the rate 8 L/min. The solution is mixed and drains from the tank at the same rate. Let y be the number of kg of salt in the tank after t minutes. Write the differential equation for this situation
Answers
Let A(t) denote the amount of salt (in kg) in the tank at time t.
At the start, there are 80 kg of salt in the tank, so A(0) = 80.
Solution flows into the tank at a rate of 8 L/min at a concentration of 0.04 kg/L, so that salt flows in at a rate of
(8 L/min) * (0.04 kg/L) = 0.32 kg/min
Solution flows out at the same rate, but its concentration depends on the amount of salt in the tank. The concentration of the solution is the proportion of salt in the liquid to the total volume of the liquid. Solution flows in and out at 8 L/min, so the volume of liquid (1000 L) stays the same. A(t) is the amount of salt in the tank, so the concentration is A(t)/1000 kg/L. Hence salt flows out at a rate of
(8 L/min) * (A(t)/1000 kg/L) = 0.008 A(t) kg/min
The net rate at which salt flows through the system is then given by the differential equation,
dA(t)/dt = 0.32 - 0.008 A(t)

Answers
Answer:
First Quartile Q1 = 9.9525
Step-by-step explanation:
For a standard normal distribution,
First quartile Q1 = μ - 0.675 σ
From the question mean μ = 10.56
Standard deviation σ = 0.9
Plugging these values into the first quartile equation, we have;

Answer:
25 inches
Step-by-step explanation:
In the diagram, we are given the following information
Height of the cone = 20 inches
Radius of the cone = 15 inches.
The formula for the slant height of a cone represented by l =
l² = r² + h²
l = √(r² + h²)
l = √(15² + 20²)
l = √(225 + 400)
l = √625
l = 25 inches
Therefore, the slant height of this cone = 25 inches
