Answer:

10√30

Step-by-step explanation:

First, we need to break the square roots into numbers that can be whole numbers.

√5 cannot be broken down so it stays √5

√12 can be broken into √4 and √3

√50 can be broken into √25 and √2

Turn √4 and √25 into whole numbers to get 2 and 5

Multiply 2 and 5 to get 10, then just multiply the square roots.

√5*√3*√2 is √30

The answer is then 10√30 when you put it together.

Hope this helps

which is the solutions to the system of equations shown { 3x - y = 6 and here is the other equation{ x - 2y = -18
Vinvika [58]

Answer:

(6, 12)

Step-by-step explanation:

{ 3x - y = 6

{ x - 2y = -18

by using elimination:

6x -2y=12

x - 2y= -18

________-

5x = 30

x = 6

y = 18-6 = 12

the solutions = {(6, 12)}

An experiment observing the growth of two germ strand populations finds these patterns.
Mice21 [21]

Answer:

R(x) = (1.3)^{3x-8}

Step-by-step explanation:

Given

A(x) = (1.3)^{x + 9}

B(x) = (1.3)^{4x + 1}

Required

Ratio B(x) to A(x)

This is calculated as:

R(x) = B(x) : A(x)

Express as fraction

R(x) = \frac{B(x) }{A(x)}

Substitute: A(x) = (1.3)^{x + 9} and  B(x) = (1.3)^{4x + 1}

R(x) = \frac{(1.3)^{4x+1}}{(1.3)^{x+9}}

Apply law of indices

R(x) = (1.3)^{4x-x+1-9}

R(x) = (1.3)^{3x-8}

Compute Δy and dy for the given values of x and dx = Δx. (Round your answers to three decimal places.) y = ex, x = 0, Δx = 0.4
kobusy [5.1K]

Answer:

0.492

Step-by-step explanation:

According to the given situation,  the calculation of Δy and dy is shown below:-

y = e^x, x = o, \Delta x = 0.6

dy = f'(x) = e^x

dy = e^x dx

= e^x (0.4)

dy = 0.4e^x

\Delta y = f(0.4) - f(0)

= e^{0.4} - e^0

Now we use the scientific calculator or spreadsheet to determine the exponential value

= 1.491824698  - 1

= 0.491824698

or

= 0.492

Therefore for computing the  Δy and dy we simply applied the above formula.

Hence, the answer is 0.4918
