Help its 11:28 due at 11:59 :((
Alja [10]

Answer:

y = 0.87x + 0.02

Step-by-step explanation:

Euros as a function of dollars means that euros is y and dollars are x.

We are given 2 points: (4, 3.5) and (10, 8.72)

slope = (8.72 - 3.5)/(10 - 4)

slope = 5.22/6 = 0.87

y = 0.87x + b

3.5 = 0.87(4) + b

b = 0.02

y = 0.87x + 0.02

In isosceles triangle ABC, AC=BC=20, the measure of angle A=68, and CD is the altitude to side AB. What is CD to the nearest 10t
antiseptic1488 [7]

Answer:

Step-by-step explanation:

Comment

The way the diagram looks when it is drawn is that you are going to need the sine function to solve for the side opposite which is CD.

Formula

Sin(A) = Sin(68 = opposite / hypotenuse     Substitute values.

Solution

sin(68) = altitude (side opposite) / 20       multiply both sides by 20

20*sin(68) = 20* altitude / 20                     substitute for sin(68)

20* 0.9272 = altitude

altitude = 18.5

Answer: 18.5 to the nearest tenth
