Answer:

29. A

30. B

31. B

32. A

34. B

38. A

Step-by-step explanation:

29. A. All possible answers

B-D Incorrect

30. $44.56 - $10 = $34.56

$34.56 ÷ $0.08 = 432

31. 0.7 × 4k = 2.8k

0.7 × -12 = -8.4

0.7 (4k - 12) = 2.8k - 8.4

32. A = Pi × Radius^2

Large circle = 380.13

Small circle = 201.06

Subtract 380.13 - 201.06 = 179.07

34. 42/500 = 8.4% = 1/12

38. There is a 0 percent chance. It is impossible.

Answer:

I figure you could simplify it by multiplying both sides by 6, resulting in -31+23=-30+18-1+5

-8=-8

Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.

Over [174]

Answer:

y = $8(-\frac{1}{2})^x$

Step-by-step explanation:

Let the equation of the exponential function is,

y = a(b)ˣ

Since the graph of this function passes through two points $(4, \frac{1}{2})$ and (3, -1)

For the point $(4, \frac{1}{2})$ ,

$\frac{1}{2}=a(b)^4$ ---------(1)

For second point (3, -1),

-1 = a(b)³ ---------(2)

Divide equation (2) by equation (1),

$\frac{\frac{1}{2}}{-1}$ = $\frac{a(b)^4}{a(b)^3}$

$-\frac{1}{2}=b^{(4-3)}$

$-\frac{1}{2}=b$

From equation (2)

-1 = $a(-\frac{1}{2})^3$

-1 = $-\frac{1}{8}a$

a = 8

Therefore, equation of the exponential function will be,

y = $8(-\frac{1}{2})^x$
