Create a 3rd degree polynomial function with one zero at three. Sketch a graph

DedPeter [7]

Answer:

$f(x) = {x}^{3} - 9 {x}^{2} + 27x - 27$

Step-by-step explanation:

We want to create a third degree polynomial function with one zero at three.

In other words, we want to find a polynomial function with roots x=3 , multiplicity, 3.

Since x=3 is a solution, x-3 is the only factor that repeats thrice.

$f(x) = {(x - 3)}^{3}$

We expand to get:

$f(x) = x( {x}^{2} - 6x + 9) - 3( {x}^{2} - 6x + 9)$

$f(x) = {x}^{3} - 6 {x}^{2} + 9x- 3 {x}^{2} + 18x - 27$

This simplifies to:

$f(x) = {x}^{3} - 9 {x}^{2} + 27x - 27$

See attachment for graph.

An ice cream shop sold 48 vanilla milkshakes in a day, which was 40% of the total number of milkshakes sold that day. What was t

german

Answer:

They sold 120 milkshakes that day

Step-by-step explanation:

We can set up a proportion

$\frac{48}{m} =\frac{2}{5}$

$48*5=2m\\ 2m = 240\\m = 120\\$

Note: If you have some value, $v$ , and it is $\frac{x}{100}$ of the total amount, you can find the value by doing the equation $\frac{v}{x}*100$

Ai Lun, a management trainee at a large New York based bank, is trying to estimate the real rate of return expected by investors

salantis [7]

Answer:

option B

Step-by-step explanation:

given,

3-month T-bill currently yields = 3%

customer price have been rising = 2% rate

Ai Lun's estimate of the real rate = ?

real rate return

= $\dfrac{1 + risk\ free\ rate}{1 +inflation\ rate} - 1$

= $\dfrac{1 + 0.03}{1 +0.02} - 1$

= $\dfrac{1.03}{1 .02} - 1$

= $1.0098 - 1$

= 0.0098

= 0.98 % ≅ 1 %

hence, the correct answer is option B
