Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.

Natalija [7]

Answer:

x=3 , x=-3

Step-by-step explanation:

$e^{lnx^2} -9= 0$

Add 9 on both sides

$e^{lnx^2}=9$

To remove base 'e' we take ln on both sides

$ln e^{lnx^2}=ln9$

$lnx^2=ln(9)$

Both sides have ln , so we make the terms equal

$x^2=9$

Take square root on both sides

$x=+-3$

x=3 , x=-3

Write the equation of a line that goes through the points (-2, -5) and (3, -10)

AlekseyPX

The equation for slope between two points is (y1-y2)/x1-x2
Plug the points into the equation

-5-(-10)/-2-3
5/5
m=1
To find the equation, use y-y1=m(x-x1)
y-(-5)=1(x-(-2))
y+5=x+2
y=x+2-5
y=x-3

Find the measure of angle A

Mariana [72]

Apply the law of cosines. and solve for A

$14^{2} = 11^{2} + 11^{2} - 2(11)(11)cos(A) \\ 
196 = 121 + 121 - 242cos(A) \\ 
-46 = -242cos(A) \\cos(A) = 0.1900826446$

A = 79.04239272, or 79
