Today, everything at a store is on sale. The store offers a 20% discount. a. The regular price of a T-shirt is $18. What is the discount price?

b. If the regular price of an item is x dollars, what is the discount price in dollars?

(Answer each question with solutions)

c. The discount price of a hat is $18. What is the regular price?

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

the answer is -1 for this question

step-by-step explanation:

i think it’s a i believe

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
