Solving exponential and logarithmic equation in exercise, solve for x or t. see example 5 and 6.
ein x = 4

x = 4

Step-by-step explanation:

eIn x = 4

In x = In 4

In on the left side cancels In on the right side

Therefore, x = 4

the first one, all those points on the line just make a strait line.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
