Plssssssss helpppppppppppp i want it now pls

spin [16.1K]

3/5kg + 760g

3/5kg = 3/5×1000

= 600g

Now

600g + 760g = 1360g

Or 1.36kg

Which of these choices show a pair of equivalent expressions? Check all that apply.

DIA [1.3K]

Answer:

(A) and (B)

Step-by-step explanation:

(A) $(8)^\frac{9}{2} and (\sqrt{8})^9$

On simplifying this, we get

$(8)^{\frac{1}{2}{\times}9}$

$(\sqrt{8})^9$

which is equivalent to the other term, thus this option is correct.

(B) $(4)^\frac{5}{2} and (\sqrt{4})5$

On simplifying this, we get

$(2)^{2{\times}\frac{5}{2}} and 32$

$32 and32$

which is equivalent to the other term, thus this option is correct.

(C) $(\sqrt[3]{125})^7 and (125)^\frac{3}{7}$

$(5)^7 and (5)^\frac{9}{7}$

which are not equivalent, thus this option is not correct.

(D) $(12)^\frac{1}{7} and (\sqrt{12})^7$

which are not equivalent, thus this option is not correct.

For the graph, which are possible functions ƒ, g, and h?

lesya692 [45]

Answer:

The third option is correct

$\displaystyle h(x)=\left ( \frac{10}{3} \right )^x$

$\displaystyle g(x)=\left ( \frac{7}{4} \right )^x$

$\displaystyle f(x)=\left ( \frac{9}{8} \right )^x$

Step-by-step explanation:

Exponential function

The exponential function is usually expressed as

$f(x)=Cr^{kx}$

If both C and k are positive, then f is increasing in all of its domain. Same happens if both are negative. They all have one point in common: (0,C)

The graph shows three functions, all increasing and in all of them (given the options for the answer) have C=1 and k=1, so the equation for each one is

$f(x)=r^{x}$

When x=1, f(1)=r lets us know the value of r

From the graph we can see that the value of r is the greatest for h(x). The next value of r is that one for g(x). Finally, f(x) has the smallest r. That means that

$h(1)>g(1)>f(1)$
