Rzqust [24]3 years ago

Answer:

3.75*A + 2.50*D = 35

A + D = 12

A = 12 - D

3.75*(12-D) +2.5*D= 35

45 - 3.75D + 2.5D = 35

45 - 1.25D = 35 |-35

10 - 1.25D = 0 |+1.25D

10 = 1.25D | /1.25

8 = D

A+D=12

A+8=12 |-8

A=4

The graph of f(x) = 24x^2 + 63x +34/ 4x + 3 has an oblique asymptote at y =
g100num [7]

<em>Correct answer is C). 6X+11</em>

Step-by-step explanation:

The given function f(x)= \frac{24x^{2} +63x + 34 }{4x+3}

On simplying the function f(x),

f(x)= \frac{6x(4x+3) -18x +63x + 34 }{4x+3}

f(x)= \frac{6x(4x+3) +45x + 34}{4x+3}

f(x)= \frac{6x(4x+3) +11(4x+3)+x-33 + 34 }{4x+3}

f(x)= \frac{6x(4x+3) +11(4x+3)+x+1}{4x+3}

f(x)=(6x+11)+\frac{(x+1)}{4x+3}

From above equation

"(6x+11)" is Oblique asymptote and \frac{(x+1)}{4x+3} is vertical asymptote

Therefore, Correct answer is C). 6X+11

Nastasia [14]

I think the answer is 30x+330>50x

Step-by-step explanation:

for the option A it was slightly changed,

cause the $30 was deposited by <em><u>helen</u></em> not <em><u>Vince.</u></em>

<em><u>so </u></em><em><u>check </u></em><em><u>that </u></em><em><u>well</u></em>

Since f(x, y) = 1 + y2 and "∂f/∂y" = 2y are continuous everywhere, the region r in theorem 1.2.1 can be taken to be the entire x
slega [8]

Answer:

The solution to the differential equation

y' = 1 + y²

is

y = tan x

Step-by-step explanation:

Given the differential equation

y' = 1 + y²

This can be written as

dy/dx = 1 + y²

Separate the variables

dy/(1 + y²) = dx

Integrate both sides

tan^(-1)y = x + c

y = tan(x+c)

Using the initial condition

y(0) = 0

0 = tan(0 + c)

tan c = 0

c = tan^(-1) 0 = 0

y = tan x
