Answer:

$960 into 6% account and $1600 into 8% account

Step-by-step explanation:

Let money put in 6% account be x

let money put in 8% account be y

How much interest did she earn?

2560 * 0.0725 = $185.6

Now, we can write:

0.06x + 0.08y = 185.6

and we know

x + y = 2560

We can say:

x = 2560 - y

and we put this into 1st equation:

0.06(2560 - y) + 0.08y = 185.6

153.6 - 0.06y + 0.08y = 185.6

0.02y = 32

y = 1600

and thus, x = 2560 - 1600 = 960

She put $960 into 6% account and $1600 into 8% account

The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval -3 ≤ x ≤ 6
victus00 [196]

Answer:

Average ROC = 0

Step-by-step explanation:

Average ROC : (f(b) - f(a)) / (b - a)  ... slope = (y'-y) / (x'-x)

a = -3   f(a) = 10   ... x=-3, y=10

b = 6    f(b) = 10   ... x'=6, y'=10

Average ROC = (10 - 10) / (6 - -3) = 0 / 9 = 0

The measure of the exterior angle of the triangle is what degree?
RSB [31]

Answer:

92°

Step-by-step explanation:

By exterior angle theorem:

(2x - 2) \degree = x \degree + 45 \degree \\  \\ (2x - 2 - x) \degree = 45 \degree \\  \\ (x - 2) \degree = 45 \degree \\  \\ (x - 2)  = 45 \\  \\ x = 45 + 2 \\  \\ x = 47 \\  \\ (2x - 2) \degree  = (2 \times 47 - 2)\degree  \\  \\ (2x - 2) \degree  = (94 - 2)\degree   \\  \\ (2x - 2) \degree  = 92\degree   \\  \\ measure  \: of  \: the  \: exterior \:  angle \\  = 92 \degree
