Tobie invests $25 in a bank account where the interest is compounded at 4% every year. He makes no withdrawals or deposits. The

GarryVolchara [31]

Answer:

Step-by-step explanation:

The initial amount of money that he invested is $25. It means that P = $25.

The interest is compounded at 4% every year. It means that

r = 4% = 4/100 = 0.04

The formula for compound interest is A(t) = P(1 + i)t. It becomes

A(t) = 25(1 + 0.04)^t

A(t) = 25(1.04)^t

Completing the table, it becomes

At t = 0,

A(0) = 25(1.04)^0

A(0) = $25

At t = 10,

A(10) = 25(1.04)^10

A(10) = $37

Point M is the midpoint of PQ. The coordinates of P and M are given below.

Zepler [3.9K]

The coordinates of Q are (-1,6)

Further Explanation:

Given points are:

$(x_m, y_m) = (5, -2)\\(x_p,y_p) = (11, -10)$

The formula for mid-pint is:

$(x_m, y_m) = (\frac{x_p+x_q}{2} , \frac{y_p+y_q}{2})\\From\ this\ we\ get\\x_m = \frac{x_p+x_q}{2}\\Putting\ values\\5 =\frac{11+x_q}{2}\\5*2 = 11+x_q\\10 = 11+x_q\\10-11 = x_q\\x_q = -1\\AND\\y_m = \frac{y_p+y_q}{2}\\-2 = \frac{-10+y_q}{2}\\-2*2 = -10+y_q\\-4 = -10+y_q\\-4+10 = y_q\\y_q = 6$

The coordinates of Q are (-1,6)

NeX [460]

Answer:

A (2, 4), B (3, 4), C'(5, 6) is formed by a translation

Step-by-step explanation:

A(1, 3), B (2, 3), C(4, 5)

A' (2, 4), B' (3, 4), C'(5, 6) ==> A(1+1, 3+1), B (2+1, 3+1), C(4+1, 5+1)
