Find the first derivative for y = f(x). fox ) 3x² -5x-1 at a Pocat where a = 4

Brums [2.3K]

Answer:

Step-by-step explanation:

f(x) = 3x² -5x - 1

f'(x) =2*3x - 5*1 +0

= 6x - 5

f'(4) = 6*4 - 5

= 24 - 5

= 19

Solve the initial-value problem<br><br> y' = x^4 - \frac{1}{x}y, y(1) = 1.

natta225 [31]

The ODE is linear:

$y'=x^4-\dfrac yx$

$y'+\dfrac yx=x^4$

Multiplying both sides by $x$ gives

$xy'+y=x^5$

Notice that the left side can be condensed as the derivative of a product:

$(xy)'=x^5$

Integrating both sides with respect to $x$ yields

$xy=\dfrac{x^6}6+C$

$\implies y(x)=\dfrac{x^5}6+\dfrac Cx$

Since $y(1)=1$ ,

$1=\dfrac16+C\implies C=\dfrac56$

so that

$\boxed{y(x)=\dfrac{x^5}6+\dfrac5{6x}}$

What is the Diference? Complete the equation

horrorfan [7]

Answer:

-3/5

Step-by-step explanation:

First, make the mixed fraction into an improper fraction:

-1 2/5 = -(5/5 + 2/5) = -(7/5)

Note that two negatives = one positive:

- (-4/5) = + 4/5

Combine the terms. Subtract the numerators:

-(7/5) + (4/5) = (-7 + 4)/5 = -3/5

-3/5 is your answer.

If p(a) = 0.50, p(b) = 0.60, and p(a intersection

bogdanovich [222]

Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)

P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80
