Mary deposits R400 every three months into a bank account earning interest at 16% per year, compounded quarterly. The approximat

ycow [4]

Answer:

The approximate time that it will take Mary to save R40000 is 29 years

Step-by-step explanation:

A= p(1+r/n)^nt

t = log(A/P) / n[log(1 + r/n)]

A = R40000

n = 4

P = R400

r = 16%

t = log(A/P) / n[log(1 + r/n)]

= log(40,000 / 400) / 4{log(1+0.16/4)}

= log(100) / 4{log(1+0.04)}

= 2 / 4{log(1.04)}

= 2 / 4(0.0170)

= 2 / 0.068

= 29.41

t = 29.41 years

Approximately 29 years

The approximate time that it will take Mary to save R40000 is 29 years

Maci made $170 grooming dogs one day with her mobile dog grooming business. She charges $60 per appointment and earned $50 in ti

V125BC [204]

Answer:

170 = 60x + 50 (let x be number of appointments)

Step-by-step explanation:

because the total is 170, it goes behind the equal sign. $50 in tip is added to the amount of appointments so it goes on the other side of the 170. the $60 per appointment goes on the 50's side

A figure is located entirely in the third quadrant. If you reflect it over y = 0. Which quadrant will the resulting figure lie i

Varvara68 [4.7K]

Answer: Quadrant 2

=================================================

Explanation:

Check out the diagram below. An example point in the third quadrant is (-2,-5). This quadrant is the southwest quadrant. Reflect the example point over the x axis (aka the line y = 0) and we get (-2,5). This is shown when we go from point A to point B in the diagram.

The reflection rule is $(x,y) \to (x,-y)$ showing that only the y coordinate changes from y to -y. If y is negative, then flip to positive, or vice versa. The x coordinate stays the same.
