Solve the problem. The formula W = 0.69g 2 - 0.01g + 7.9 models the average weight, W, in ounces, for a mouse who is fed g grams per day of a special food. According to the formula, how much will a mouse weigh when it is fed 13 grams of the special food per day? If necessary, round answers to the nearest hundredth.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
