Note your teacher will grade your response to ensure you receive proper credit for your answer a quadratic equation can be written in vertex form or in standard form

vertex form:  y = a(x – h)2 + k, where (h, k) is the vertex

standard form:  y = ax^2 + bx + c

Step-by-step explanation:

not certain what the qustion is

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
