### Over the last 12 month, Petco has lost a total of $1824.00 due to shoplifting. Write and solve an equation that shows how much money Petco lost each month. ( Since they have lost the money, remember that you need to use negative integers to represent the situation correctly.) Take y=mx+b let x=years and y=lost money then divide 1824 by 12 = 152 and since it is a loss make it into -152 and insert it for m as the constant rate of loss per month your answer should be y=-152x. if the store has a starting amount of money plug that into b.

Use this formula: Area = * radius^2 We know the radius is 4 yards. Area = 3.14 * 4^2 Area = 3.14 * 16 Area = 50.24 Now for the square. Double the radius to get the diameter to get the length of the side. 4 * 2 = 8 Formula for finding the area of a square is Area = side^2 Area = 8^2 Area = 64 And because we only want to shaded portion, we will subtract the area of the circle from the square. 64 - 50.24 = 13.76 So, D) 13.76 square yards is the answer to this question.

QUESTION POSTED AT 30/03/2020 - 01:33 AM

### Consider the vector v=(-7,8). What is the angle between v=(-7,8) and the positive x-axis? Part 1: Use the formula v1 x v2=|v1||v2|cos theta to find the cosine of the angle between the two vectors (-7,8) and (1,0).

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°
Solving for angle between v and positive x-axis:
180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ
Calculating for the dot product of the vector:
v1 x v2 = -7*1 + 8*0 = -7
Calculating vector magnitude:
|v1| = √(-7²+8²) = √113
|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

### Find the area and peri19.6 ft13 ftA

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :
