Activity 1: Quadratic or Not A. Write QE if the equation represents a quadratic equation and NQE if it is not. 1. Α = πη2 2. x + 4x² = 0 3. (x - 2)2 = 0 4. (x + 3) + 8 = 0 5. x² = 5

y=mx+b

step-by-step explanation:

m slope, b y-intercept

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

14

step-by-step explanation:

14 x 3 = 42

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!
