Consider the numbers 0, 10, 20, 30, and 40. Multiply each by 4 and compare the result to 60 to determine into which of the follo

olya-2409 [2.1K]

Answer:

b) 10 to 20

Step-by-step explanation:

You have to multiply each of the given numbers by 4, and add 8 to that result.

So:

0*4+8 = 8

10*4+8 = 48

20*4+8 = 88

30*4+8 = 128

40*4+8 = 168

And 60 is between the result of 10 and 20, so that's the interval you have to select.

The correct answer is b) 10 to 20

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

What is the equation of exponential regression equation? Round all numbers you your answer to three decimal places

ExtremeBDS [4]

Given:

The given values are:

$a=0.2094539899$

$b=2.507467975$

$r^2=0.9435996398$

$r=0.9713905701$

To find:

The exponential regression equation for the given values (Rounded to three decimal places).

Solution:

The general form of exponential regression equation is:

$y=a\cdot b^x$ ...(i)

Where, a is the initial value and b is the growth/decay factor.

We have,

$a=0.2094539899$

$b=2.507467975$

Round these numbers to three decimal places.

$a\approx 0.209$

$b\approx 2.507$

Substitute $a=0.209, b=2.507$ in (i) to find the exponential regression equation.

$\hat{y}=0.209\cdot 2.507^x$

Therefore, the correct option is C.
