Answer:

The simplified form of the provided expression is $8x^{5} - 6x^{4} + 12x^{3}$

Step-by-step explanation:

Consider the provided expression.

$2x^2(4x^3 - 3x^2 + 6x)$

Use the distributive property:

$a(b+c)=ab+ac$

By using the above property we can simplify it as shown:

$2x^2(4x^3 - 3x^2 + 6x)$

$8x^{(2+3)} - 6x^{(2+2)} + 12x^{(2+1)}$

$8x^{5} - 6x^{4} + 12x^{3}$

Thus, the simplified form of the provided expression is $8x^{5} - 6x^{4} + 12x^{3}$

atroni [7]

First month's profit of the company = $2,400.

After the first month, the profit is modeled by the function

J(t) = 2.5t + 1,250, t is the number of months after the first month the shop opened.

Now, P(t) describes the total profit earned by the company.

So, P(t) = (Profit earned from first month) + (Profit earned from remaining 11 months of the year)

= 2400 + (2.5t + 1250)

= 2.5t + 3650

Hence, total profit earned for the year = 2.5t + 3650.

Answer:

-3+15i

Step-by-step explanation:

Apply complex arithmetic rule: $\left(a+bi\right)\left(c+di\right)=\left(ac-bd\right)+\left(ad+bc\right)i$

$\left(-3\cdot \:3-3\left(-2\right)\right)+\left(-3\left(-2\right)+3\cdot \:3\right)i$

-3 * 3 -3 (-2) = -3

$-3+15i$

Complete parts (a) through (c) below.

Yuki888 [10]

Answer:

a) $t_{crit}= 1.34$

b) $t_{crit}=-2.539$

c) $t_{crit}=\pm 2.228$

Step-by-step explanation:

Part a

The significance level given is $\alpha=0.1$ and the degrees of freedom are given by:

$df = n-1= 15$

Since we are conducting a right tailed test we need to find a critical value on the t distirbution who accumulates 0.1 of the area in the right and we got:

$t_{crit}= 1.34$

Part b

The significance level given is $\alpha=0.01$ and the degrees of freedom are given by:

$df = n-1= 20-1=19$

Since we are conducting a left tailed test we need to find a critical value on the t distirbution who accumulates 0.01 of the area in the left and we got:

$t_{crit}=-2.539$

Part c

The significance level given is $\alpha=0.05$ and $\alpha/2 =0.025$ and the degrees of freedom are given by:

$df = n-1= 11-1=10$

Since we are conducting a two tailed test we need to find a critical value on the t distirbution who accumulates 0.025 of the area on each tail and we got:

$t_{crit}=\pm 2.228$
