Answer:

$d. \: \: \: 25 {x}^{6}$

Step-by-step explanation:

Given,

Side of the square

$= 5 {x}^{3}$

Therefore, area of the square = side × side

$= {5x}^{3} \times 5 {x}^{3}$

$= 5 \times 5 \times {x}^{3 + 3}$

$= 25 {x}^{6}$

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

What is the identity property

Montano1993 [528]

The identity property shows us that any number that adds zero to itself stays itself. The identity for multiplication tells us that any number multiplied by one is itself.

Can somebody like tell me the answer

nasty-shy [4]

Answer:

Mason is incorrect.

Step-by-step explanation:

Equivalent ratios are formed when the same number is MULTIPLIED to each number in the ratior, not when the same number is added. So for example, a ratio equivalent to 2:3 would be 4:6, because 2*2=4 and 3*2=6. You multiply to create equivalent ratios, not add.

(That would be your explanation)
