Write the exact value solution and an approximation for 10^4x=25

Murrr4er [49]

Answer:

exact value: $x= \frac{log25}{4}$

approximate: x=0.349485

Step-by-step explanation:

Exact Value:

$10^{4x} = 25$

$log (10^{4x})= log 25$

$4x = log 25$

$x= \frac{log25}{4}$

Approximate:

$x= \frac{log25}{4}$

$x=1.39794/4\\$

$x=0.349485$

The base of a triangle is nine centimeters longer than the perpendicular height. If the area of the triangle is 180 square centi

Rom4ik [11]

Answer:

Step-by-step explanation:

<u>Equations</u>

Let's call

b= base of the triangle

h=height of the triangle

The base is 9 cm longer than the height, thus:

b = h + 9

The area of the triangle is:

$\displaystyle A=\frac{bh}{2}$

$\displaystyle A=\frac{(h+9)h}{2}$

And its value is 180:

$\displaystyle \frac{(h+9)h}{2}=180$

Multiplying by 2:

$(h+9)h=360$

Operating:

$h^2+9h-360=0$

Factoring:

$(h-15)(h+24)=0$

The only valid positive solution is:

h = 15 cm

And b = h + 9 = 24

b = 24 cm

The base is 24 cm long.
