Karen borrowed a sum of money for some big screen TVs and a waterfall for her restaurant. If she borrowed $10,200 and received a 3.85 % interest rate compounded continuously, how much did Karen pay in interest over a 7 year period? Round your answer to the nearest whole number
Answer:
3155
Step-by-step explanation:
Continously compounding interest formula:
PV*e^(rt)
10200*e^(.0385*7)=13354.95825
To find the amount of interest paid subtract the original amount
13354.95825-10200=3154.958249
which rounds to
3155

Gymnast Clothing manufactures expensive hockey jerseys for sale to college bookstores in runs of up to 150. Its cost (in dollars) for a run of hockey jerseys is ()=1500+10+0.42. Gymnast Clothing sells the jerseys at 90 each. Find a. The revenue function. b. Profit function c. The number of Jerseys that Gymnast Clothing manufacture to make a profit
Answer: See explanation
Step-by-step explanation:
a. The revenue function.
The revenue function will be:
= 90 × x
= 90x
b. Profit function
This will be:
= Revenue - Cost
= 90x - (1500 + 10x + 0.2x²)
= 90x - 1500 - 10x - 0.2x²
= 90x - 10x - 1500 - 0.2x²
= 80x - 1500 - 0.2x²
c. The number of Jerseys that Gymnast Clothing manufacture to make a profit
80x - 1500 - 0.2x²
0.2x² - 80x + 1500 = 0
Solving using almighty formula, x will be 20. Therefore, 20 jerseys need to be produced to make a profit.

Step-by-step explanation:
The top and bottom horizontal lines are 11 units long and the left and right vertical lines are 9 units long. Dilating the logo by a factor of one-half means that these lengths will grow longer by 50%. Hence the horizontal lines will get longer by 5.5 units and vertical lines will grow longer by 4.5 units. The diagonals should also increase in length accordingly.

Transform pentagon ABCDE according to (x, y) + (x - 2, y - 3). Which new coordinates are correct for pentagon A'B'C'D'E
A) A'(-1,3)
B) B'(3, 4)
C) C'(6,-1)
D) D'(2,-4)
E) E'(-6, -5)
The correct coordinates are A'(-1,3) and C'(6,-1)
Transformation of coordinatesFrom the given figure, we have the coordinates ABCDE under the translation (x, y) + (x - 2, y - 3)
Given the following coordinate points (1, 6), B(6, 6), C(8, 2), D(4, -2) and E(-2, -5). The resulting coordinate after transformation will be:
A = (1-2, 6-3) = (-1, 3)B = (6-2, 6-3) = B'(4, 3) C = (8-2, 2-3) = C'(6,-1) D = (4-2, -2-3) D'(2,-5) E = (-2-2, -5-3) = E'(-4, -8)Hence the correct coordinates are A'(-1,3) and C'(6,-1)

The area of the parallelogram below is___square meters
Answer:
48 m^2
Step-by-step explanation:
Since this is a parallelogram, you can think of it as taking the triangle off of the left side and reattaching it on the right side to make a rectangle. After you visualize it as a rectangle, you just have to multiply 8 by 6 to get 48 meters squared.

A box in the shape of a rectangular prism has a length of 3 5/8 inches, a width of 2 1/2 inches, and a height of 4 inches. What is the volume of the box?
Answer:
36 1/4 in³
Step-by-step explanation:
v = 3 5/8 * 2 1/2 * 4
Convert to improper fractions
v = 29/8 * 5/2 * 4/1

Find the possible value of "a" using the distance formula.
(4,-1) and (a,5) with d = 10
Answer:
[tex]a=12\text{ or } -4[/tex]
Step-by-step explanation:
The distance formula is given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We are given the two points (4, -1) and (a, 5). The distance between them is 10.
Let (4, -1) be (x₁, y₁) and let (a, 5) be (x₂, y₂). Substitute:
[tex]10=\sqrt{(a-4)^2+(5-(-1))^2}[/tex]
Solve for a. Square both sides and simplify:
[tex]100=(a-4)^2+(6)^2[/tex]
Simplify:
[tex]64=(a-4)^2[/tex]
Take the square root of both sides. Since we are taking an even root, we will need plus/minus. Hence:
[tex]\pm\sqrt{64}=\pm8=a-4[/tex]
Solve for a:
[tex]a-4=8\Rightarrow a=12\text{ or } a-4=-8\Rightarrow a=-4[/tex]
So, our two possible points are (12, 5) or (-4, 5).
