When matrices are equal, corresponding terms are equal.

... 5x - 8 = 2

... 5x = 10 . . . . . . . . add 8

... x = 2 . . . . . . . . . divide by 5

The graph of a sine function g(x) is presented below.

NISA [10]

Solution

To determine the vertical translation

We need to determine the amplitude

The amplitude is

$\frac{10-4}{2}=\frac{6}{2}=3$

Since the minimum is 4

Hence, the Vertical shift is 3+4 = 7

Part B

Given f(x) = 4 sin(θ - 45) + 8

The vertical translation is 8

$800 deposit over 10 years with an interest rate of 2%

TiliK225 [7]

Answer:

the interest is 960.

Step-by-step explanation:

the formula: I=prt i=interest p= pricipal [the money you start with]

r= rate t= time

I=? I= 800 (0.02) (10)

P= $800 I= 160+ 800 {because $160 is added}

R= 2% --> 0.02 [as a decimal] I= $960

T= 10 years
