Answer:

Correct options are B, C and E.

Step-by-step explanation:

From the graph, we see that,

A. The graph is a decreasing as the number of years are increasing.

So, the function is not representing an exponential growth.

B. From the graph, we see that,

At 0 years, the function value is at 500,000.

Thus, there was $500,000 initially when the owner started making withdrawals

C. From the graph, we see that,

At 10 years, the function value is at 300,000.

Thus, after 10 years, there is exactly $300,000 left in the account.

D. We have that, 'The amount that the owner withdraws is given by the slope of the points'.

So, the slope at different points is given by,

$\frac{300,000-500,000}{10-0}=\frac{-200,000}{10}=-200,00$

$\frac{100,000-200,000}{30-10}=\frac{-100,000}{10}=-100,00$

So, the amount withdrew each year is not same.

E. As, the y-axis represents the amount of money remaining when the owner started withdrawing.

The y-intercept is the point when the graph crosses y-axis i.e. when x = 0.

So, the y-intercept represents the amount of money withdrew at 0 years.

Thus, y-intercept represents the amount of money in the account when the owner started making withdrawals.

Hence, the correct options are B, C and E.

An exponential function, f, passes through the points (-2,-4) and (1,10). Which two points would lie on the graph of function g

Lubov Fominskaja [6]

Answer:

(-2,-12) and (1,30)

Step-by-step explanation:

we know that

f(x) passes through the points (-2,-4) and (1,10)

That means

For x=-2 ----> f(-2)=-4

For x=1 ----> f(1)=10

we have

g(x)=3f(x)

substitute the given value of f(x) to obtain the value of the function g(x)

For x=-2 -----> g(-2)=3f(-2) ----> g(-2)=3(-4)=-12

For x=1 -----> g(1)=3f(1) ----> g(1)=3(10)=30

therefore

The two points that would lie on the graph of function g are

(-2,-12) and (1,30)

(Please i need help) The expression p - 0.15p can be used to calculate the final cost of an item that has a price of p and is

garri49 [273]

Answer:

Final cost of the item is $19.55

Step-by-step explanation:

Expression representing the final cost of an item with original price = $p and discount = 15% will be,

Final cost = (p - 0.15p)

If the original price p = $23

By substituting p = 23 in the expression given,

Final cost after discount = 23 - (0.15)23

= 23 - 3.45

= $19.55

Therefore, final cost of the item is $19.55

Which choice is equivalent to the quotient shown here when x>0

Simora [160]

${\sqrt{\frac{72x^{3}}{50x^{{2}}}} = \frac{\sqrt{72x^{3}}}{\sqrt{50x^{2}}} = \frac {\sqrt{36 * x^{2} * 2 * x}}{\sqrt{25 * x^{2} * 2}} = \frac{\sqrt{36}\sqrt{x^{2}}\sqrt{2}\sqrt{x}}{\sqrt{25}\sqrt{x^{2}}\sqrt{2}} = \frac{6x\sqrt{2x}}{5x\sqrt{2}} = 1\frac{1}{5}\sqrt{x}$

The answer is equal to C. $\frac{6\sqrt{x}}{5}$ .
