Find dy/dx and d2y/dx2, and find the slope and concavity (if possible) at the given value of the parameter. (If an answer does n

ella [17]

Answer:

The slope of the function is ²/₃ and since the second derivative is zero, the concavity doesn't exist.

Step-by-step explanation:

Given;

x = 6t

y = 4t - 3

point t = 4

$\frac{dy}{dx} = (\frac{dy}{dt} )/(\frac{dx}{dt} )=\frac{\frac{dy}{dt} }{\frac{dx}{dt}} \\\\\frac{dy}{dt} = 4; \frac{dx}{dt} = 6\\\\\frac{dy}{dx} =\frac{4}{6} = \frac{2}{3}$

The slope of the function is ²/₃

take the second derivative of the function;

the second derivative will be zero since the first derivative is a constant value.

$\frac{d^2y}{dx^2} = 0$

Since the second derivative is zero, the concavity doesn't exist.

Four friends played mini golf. Their scores were –3, –2, –1, and 2. What is the mean absolute deviation of their scores?

yulyashka [42]

Answer is 1.5
You would first find the mean, you add all together then divided it by the numbers that it has, they have 4 number -3, -2, -1, 2 in this problem.
Add all number together divided it by 4, you'll get -1, (-3 + -2 + -1 + 2) ÷ 4 = -1) Then you subtract the mean by the numbers you used to get your mean so in this case it is 3, -2, -1, 2.
-3-(-1)= -2
-2-(-1)= -1
-1-(-1)= 0
2-(-1)= 3

Then you add the answers up but you have to turn the negative numbers to positive like -2 turns into just 2 and so does -1 to 1. (2+1+0+3= 1.5) Then you divide the 6 by how many numbers there are so in this case there are 4 numbers so you do 6 divided by 4 and you get 1.5. (Trust me I learned this)

There are 60 minutes in an hour. The total number of minutes is a function of the number of hours, as shown in the table. Does t

Alexxx [7]

Answer:

Step-by-step explanation:

It represents a linear function because there is a constant rate of change.

Step-by-step explanation:

Since, if the rate of change for y ( output value ) with respect to x ( input value ) remains constant for a function then it is called linear function.

Here, number of hours represents input value and minutes represents the output value,

Now, By the given table,

The function is passing through the points (1,60), (2,120), (3,180), (4,240) and (5,300),

Also,

⇒ The rate of change output value with respect to input value remains constant,

Hence, It represents a linear function because there is a constant rate of change.

A part of exponential function fis graphed on the grid.

gtnhenbr [62]

The domain is the x-values used by the graph, so you want to see how your graph lines up with respect to the x-axis.

This graph starts out with an x-value of 2 (although it doesn't really use 2, since it's an open circle) and then continues to the right forever.

The domain is x > –2.
