What is the average time in seconds between 2.15 2.05 2.02

Answers

Answer:

[tex]Average = 2.073[/tex]

Step-by-step explanation:

Given:

Time: 2.15, 2.05, 2.02

Required

Determine the average

Average is calculated as thus:

[tex]Average = \frac{\sum x}{n}[/tex]

In this case:

[tex]\sum x = 2.15+2.05+2.02[/tex]

and

[tex]n = 3[/tex]

[tex]Average = \frac{\sum x}{n}[/tex] becomes

[tex]Average = \frac{2.15+2.05+2.02}{3}[/tex]

[tex]Average = \frac{6.22}{3}[/tex]

[tex]Average = 2.073[/tex]

p(1)-P(-1)
divides it int

Answers

Answer:

[tex]p(1) - p(-1) =8[/tex]

Step-by-step explanation:

Given

[tex]p(m) = 4m^3 + 3[/tex]

Required

[tex]p(1) - p(-1)[/tex]

First, we calculate p(1)

Substitute 1 for m in [tex]p(m) = 4m^3 + 3[/tex]

[tex]p(1) = 4(1)^3 + 3[/tex]

[tex]p(1) = 4*1 + 3[/tex]

[tex]p(1) = 4 + 3[/tex]

[tex]p(1) = 7[/tex]

Next, we calculate p(-1)

Substitute -1 for m in [tex]p(m) = 4m^3 + 3[/tex]

[tex]p(-1) = 4(-1)^3 + 3[/tex]

[tex]p(-1) = 4*-1 + 3[/tex]

[tex]p(-1) = -4 + 3[/tex]

[tex]p(-1) = -1[/tex]

[tex]p(1) - p(-1)[/tex] is then calculated as:

[tex]p(1) - p(-1) = 7 - (-1)[/tex]

[tex]p(1) - p(-1) = 7+1[/tex]

[tex]p(1) - p(-1) =8[/tex]

Can someone pls help me find the second derivative of this. I need to find the concave up and down intervals but I’m having trouble getting the second derivative

Answers

Starting from

[tex]f(x)=\dfrac14(x+1)^{\frac83}-4(x+1)^{\frac23}[/tex]

take the first derivative using the power and chain rules:

[tex]f'(x)=\dfrac83\cdot\dfrac14(x+1)^{\frac83-1}-\dfrac23\cdot4(x+1)^{\frac23-1}[/tex]

[tex]f'(x)=\dfrac23(x+1)^{\frac53}-\dfrac83(x+1)^{-\frac13}[/tex]

Now take the second derivative:

[tex]f''(x)=\dfrac53\cdot\dfrac23(x+1)^{\frac53-1}-\left(-\dfrac13\right)\cdot\dfrac83(x+1)^{-\frac13-1}[/tex]

[tex]f''(x)=\boxed{\dfrac{10}9(x+1)^{\frac23}+\dfrac89(x+1)^{-\frac43}}[/tex]

Optionally, you can condense the second derivative a bit by factoring out [tex]\frac89(x+1)^{-\frac43}[/tex], which gives

[tex]f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^{\frac63}+1\right)[/tex]

[tex]f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^2+1\right)[/tex]

[tex]f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80x^2+160x+81\right)[/tex]

Answer:

Table (4)

Step-by-step explanation:

If data in the given tables show the proportional relation then they will follow the rule,

y = kx

k = [tex]\frac{y}{x}[/tex]

where 'k' = proportionality constant

From table (1),

k = [tex]\frac{2}{1}[/tex] = 2

k = [tex]\frac{3}{2}=1.5[/tex]

But 2 ≠ 1.5

So the data in the table (1) is not proportional.

Table (2)

k = [tex]\frac{0}{2}=0[/tex]

k = [tex]\frac{2}{4}=0.5[/tex]

Therefore, data in the table is not proportional.

Table (3)

k = [tex]\frac{1}{0}[/tex] = Not defined

k = [tex]\frac{3}{2}=1.5[/tex]

Data is not proportional.

Table (4)

k = [tex]\frac{y}{x}=\frac{-6}{-2}[/tex]

  = 3

k = [tex]\frac{3}{1}=3[/tex]

3 = 3

Therefore, data given in table (4) represents the proportional relationship.

Step-by-step explanation:

a) You cannot draw the graph around x=0 without lifting your pencil. The function is not continuous at x=0.

__

b) You can draw the graph around x=1 without lifting your pencil. The function is continuous at x=1.

_____

Additional comment

In technical terms, the limit from the left at x=0 is 2; the limit from the right is 3. These are different, so the function is not continuous there.

On the other hand, the left and right limits at x=1 are the same (both 2), and are equal to the value of the function at that point (f(1)=2). Hence, the function is continuous at x=1.

The measure of the largest angle is 72º.

Step-by-step explanation:

We will first solve for x. We know that the sum of the interior angles of a triangle is 180º, so 15x + 21x + 24x is equal to 180º. This means that 60x = 180º, so x = 3º. The largest angle is 24x, which is 72º.

Step 1: Flip the equation.

1.5x−10=35

Step 2: Add 10 to both sides.

1.5x−10+10=35+10

1.5x=45

Step 3: Divide both sides by 1.5.
