Answer:

AB = 6.5

Step-by-step explanation:

C = 59°

AC = 7

CD = 6

AB = ?

Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)

AB² = 7² + 6² - 2(7)(6)*Cos(59)

AB² = 85 - 43.26

AB² = 41.74

AB = √41.74

AB = 6.5 (nearest tenth)

Find the slope from points (9,-13), (7,-11)? That’s what my question is for my math homework.
musickatia [10]

Givens.

The points are (9, -13) and (7, -11).

Use the slope formula.

m=\frac{y_2-y_1}{x_2-x_1}

Where,

\begin{gathered} x_1=9,x_2=7 \\ y_1=-13,y_2=-11 \end{gathered}m=\frac{-11-(-13)}{7-9}=\frac{-11+13}{-2}=\frac{2}{-2}=-1

Therefore, the slope is -1.

A health club charges an initial fee of $100 to join, plus a fee of $33 per month. Write an algebraic equation. How much will yo
docker41 [41]
#1 answer: y=33x+100

explanation: The initial fee of $100 is your y-intercept.
The 33 is your slope.
You pay $33 a month which is what the x value represents (the month).
So your total equation is y=33x+100

#2 answer: $265

explanation: using the equation y= 33x + 100 you replace the x which is 5.
33(5) + 100. 33 * 5 = $165 but you can’t forget the + 100.
Therefore your answer will be $265.
