Answer:

solution is

x=1.353,y=1.613

Step-by-step explanation:

We are given equation as

log_2(3x-1)=log_4(x+8)

Firstly, we will find equations

First equation is

y=log_2(3x-1)

Second equation is

y=log_4(x+8)

now, we can draw graph

and then we can find intersection point

we can see that

intersection point is (1.353,1.613)

so, solution is

x=1.353,y=1.613

Answer:

The solution to the given equation is at point (1.353, 1.613).           Step-by-step explanation:

Given : Kim solved the equation below by graphing a system of equations.  

\log_2(3x-1)=\log_4(x+8)

To find : What is the approximate solution to the equation?

Solution :  

Let, y_1=\log_2(3x-1)

and  y_2=\log_4(x+8)

Now, we plot these two equations.

The graph of y_1=\log_2(3x-1) is shown with red line.

The graph of y_2=\log_4(x+8) is shown with blue line.

The solution to this system will be their intersection point.  

The intersection point of these graph is (1.353, 1.613)

Refer the attached graph below.

Therefore, The solution to the given equation is at point (1.353, 1.613).

Simplify:<br> −z3+5k6−(−z3+10k6)
natta225 [31]

Answer:

The answer to your question is        -5k⁶

Step-by-step explanation:

Polynomial

                                      - z³  + 5k⁶  - (-z³ + 10k⁶)

Use law of signs for the parenthesis

                                     - z³  + 5k⁶ + z³  - 10k⁶

Use associative property for like terms

                                    (-z³ + z³) + (5k⁶ - 10k⁶)

Simplify like terms

                                    (0)  +   (-5k⁶)

Result

                                               -5k⁶

Use a trigonometric ratio to find the distance EF.
leonid [27]

Answer:

The height of the building is approximately <u>73 m</u>.

Step-by-step explanation:

The triangle EFG is shown below.

Given:

Length of shadow of building is, FG=34\ m

Angle of inclination of Sun with the vertical is 25°.

Therefore, the angle of inclination of Sun with the horizontal is given as:

\angle G=90-25=65\°

Now, in triangle EFG as shown below, we use the tangent ratio to determine the height of building EF. Therefore,

\tan (\angle G)=\frac{EF}{FG}\\\tan 65\°=\frac{EF}{34}\\EF=34\times \tan 65\°=72.9\ m\approx 73\ m

Therefore, the height of the building is approximately 73 m.
