Approximate R' by using a linear approximation: for x close enough to 24, you have

R'(x) ≈ L(x) = R' (20) + R'' (20) (x - 20)

Then

R' (24) ≈ R' (20) + R'' (20) (24 - 20) = -4 + 50 (24 - 20) = 196

Answer:

We conclude that:

The number of people who ordered the chicken dinner = 1

The number of people who ordered the steak dinner = 5

Step-by-step explanation:

Given that

Some order the chicken dinner for $14

some order the steak dinner for $17.

Total bill = $99

Let 'n' be the number of people who ordered the chicken dinner.

Let '6-n' be the number of people who ordered the steak dinner.

Thus, the equation becomes

$14n + 17(6-n) = 99$

$14n + 102 - 17n = 99$

$-3n = 99 - 102$

$-3n = -3$

Divide both sides by -3

$n = 1$

and

$6-n = 6-1 = 5$

Therefore, we conclude that:

The number of people who ordered the chicken dinner = 1

The number of people who ordered the steak dinner = 5

Given a circle in the complex plane with a diameter that has endpoints at: -12 − i and 18 + 15i Find the center of the circle. +

azamat

Answer: The center of the circle is 3+7i

Explanation: Let z1 and z1 be the two end points and c be the center to be determined. The center lies half of the difference between z1 and z1, measured from z1:

$z_1=-12-i\\z_2=18+15i\\c=z_1+\frac{z_2-z_1}{2}=-12-i +15+8i=3+7i$
