Step-by-step explanation:

From the figure it is clear that:

x+110°=180

x=180-110

x=70

For y:

the left exterior angle of line q is also70.

By the definition of alternate exterior angle:

y=70

I know this is an exponential function based on the fact the f(x) multiplies. But how do I get an equation from the table? I wil
almond37 [142]

Answer:An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

Step 1: Take the natural log of both sides:

Step 2: Simplify the left side of the above equation using Logarithmic Rule 3:

Step 3: Simplify the left side of the above equation: Since Ln(e)=1, the equation reads

Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80)..

Check: Check your answer in the original equation.

Example 2: Solve for x in the equation tex2html_wrap_inline133

Step 1: Isolate the exponential term before you take the common log of both sides. Therefore, add 8 to both sides: tex2html_wrap_inline135

   

Step 2: Take the common log of both sides:

Step 3: Simplify the left side of the above equation using Logarithmic Rule 3:

Step 4: Simplify the left side of the above equation: Since Log(10) = 1, the above equation can be written

Step 5: Subtract 5 from both sides of the above equation:

is the exact answer. x = -3.16749108729 is an approximate answer..
