ss7ja [257]

Answer:

The answer is below

Step-by-step explanation:

The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is given by:

AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\

Point J is at (-3, 3), point K is at (4, 3) and point L is at (1, -1). Hence:

The distance between K and L = KL = \sqrt{(-1-3)^2+(1-4)^2} =5\ units

The distance between J and L = JL = \sqrt{(-1-3)^2+(1-(-3))^2} =4\sqrt{2} \ units

The distance between K and J = JK = \sqrt{(3-3)^2+(-3-4)^2} =7\ units

Therefore, the perimeter of triangle JKL is:

Perimeter = KL + JL + JK = 5 + 4√2 + 7 = 17.66 units

What is the percent decrease modeled in the function (picture)
yanalaym [24]
For this case we have a function of the form:
 y = A (b) ^ x
 Where,
 A: initial amount
 b: decrease rate
 x: time
 We have then:
 b = 0.15
 Therefore the percentage of decrease is:
 (1-0.15) * 100 = 75%
 Answer:
 
75%
