Answer:

C, 5/2

Step-by-step explanation:

3 I2x -1I + 4 = 16

Isolate absolute value:

3 I2x -1I + 4 - 4 = 16 - 4

3 I2x -1I= 12

(3 I2x -1I) / 3 = 12 / 3

I2x -1I= 4

Since the question is only asking for the positive, all you need to solve for is the +4. Solve for x

2x -1 = 4

2x -1 + 1 = 4 +1

2x = 5

2x / 2 = 5 / 2

x = 5/2 or C

the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an

kari74 [83]

Given:

The equation of given line is

$y=3x-4$

A line is perpendicular to the given line and passes through the point (9,5).

To find:

The equation of the perpendicular line.

Solution:

We have,

$y=3x-4$

On comparing this equation with slope intercept form $y=mx+b$ , we get

$m=3$

It means, the slope of the given line is 3.

The product of slopes of two perpendicular lines is -1.

$m\times m_1=-1$

$3\times m_1=-1$

$m_1=-\dfrac{1}{3}$

Point slope form of a line is

$y-y_1=m(x-x_1)$

Where, m is the slope.

The slope of perpendicular line is $-\dfrac{1}{3}$ and it passes through the point (9,5). So the equation of the line is

$y-5=-\dfrac{1}{3}(x-9)$

$y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)$

$y-5=-\dfrac{1}{3}x+3$

Adding 5 on both sides, we get

$y-5+5=-\dfrac{1}{3}x+3+5$

$y=-\dfrac{1}{3}x+8$

Therefore, the equation of required line is $y=-\dfrac{1}{3}x+8$ .

Solve x'=5t(sqrt(x)) x(0)=1

LekaFEV [45]

Answer:

$2\sqrt{x}=\frac{5t^2}{2}+2$

Step-by-step explanation:

Given: $\frac{\mathrm{d} x}{\mathrm{d} t}=5t\sqrt{x}\,,\, x(0)=1$

Solution:

A differential equation is said to be separable if it can be written separately as functions of two variables.

Given equation is separable.

We can write this equation as follows:

$\frac{dx}{\sqrt{x}}=5t\,dt$

On integrating both sides, we get

$\int \frac{dx}{\sqrt{x}}=\int 5t\,dt$

Formulae Used:

$\int \frac{1}{\sqrt{x}}=2\sqrt{x}\,\,,\,\,\int t\,dt=\frac{t^2}{2}$

So, we get solution as $2\sqrt{x}=\frac{5t^2}{2}+C$

Applying condition: x(0) = 1, we get $C=2$

Therefore, $2\sqrt{x}=\frac{5t^2}{2}+2$
