20% off. Sales tax is 8%. Sallie says she has enough money to buy the skateboard.
The discounted sale price of the skateboard without tax can be found by multiplying the regular price by _____ . The total cost for the skateboard with sales tax can be found by multiplying the discounted sale price by ________. The total cost for the skateboard will be ______$. Sallie (has, or does not have) enough money to buy the skateboard.

Sallie has $115 which is not enough to buy the skateboard as it costs $119.22

Step-by-step explanation:

Given,

Regular price of skateboard = $137.99

Discount = 20% = $\frac{20}{100}=0.2$

The discounted sale price of the skateboard without tax can be found by multiplying the regular price by <u>0.2</u>

Discount = 137.99*0.2 = $27.60

Discounted sale price = Regular price - discount

$Discounted\ sales\ price = 137.99-27.60\\Discounted\ sales\ price = \$110.39\\$

Sales tax = 8% = $\frac{8}{100}=0.08$

The total amount of sales tax can be found by multiplying the discounted sale price by <u>0.08</u>

Total cost with sales tax = 110.39*0.08 = $8.83

Total cost of skateboard = Discounted sale price + sales tax

Total cost of skateboard = $110.39+8.83 =\$119.22$

Sallie has $115 which is not enough to buy the skateboard as it costs $119.22

Part A: Create a third-degree polynomial in standard form. How do you know it is in standard form? (5 points)

Svetlanka [38]

Answer:

(See explanation for further details)

Step-by-step explanation:

a) Let consider the polynomial $p(x) = 5\cdot x^{3} +2\cdot x^{2} - 6 \cdot x +17$ . The polynomial is in standards when has the form $p(x) = \Sigma \limit_{i=0}^{n} \,a_{i}\cdot x^{i}$ , where $n$ is the order of the polynomial. The example has the following information:

$n = 3$ , $a_{0} = 17$ , $a_{1} = -6$ , $a_{2} = 2$ , $a_{3} = 5$ .

b) The closure property means that polynomials must be closed with respect to addition and multiplication, which is demonstrated hereafter:

Closure with respect to addition:

Let consider polynomials $p_{1}$ and $p_{2}$ such that:

$p_{1} = \Sigma \limits_{i=0}^{m} \,a_{i}\cdot x^{i}$ and $p_{2} = \Sigma \limits_{i=0}^{n}\,b_{i}\cdot x^{i}$ , where $m \geq n$

$p_{1}+p_{2} = \Sigma \limits_{i=0}^{n}\,(a_{i}+b_{i})\cdot x^{i} + \Sigma_{i=n+1}^{m}\,a_{i} \cdot x^{i}$

Hence, polynomials are closed with respect to addition.

Closure with respect to multiplication:

Let be $p_{1}$ a polynomial such that:

$p_{1} = \Sigma \limits_{i=0}^{m} \,a_{i}\cdot x^{i}$

And $\alpha$ an scalar. If the polynomial is multiplied by the scalar number, then:

$\alpha \cdot p_{1} = \alpha \cdot \Sigma \limits_{i = 0}^{m}\,a_{i}\cdot x^{i}$

Lastly, the following expression is constructed by distributive property:

$\alpha \cdot p_{1} = \Sigma \limits_{i=0}^{m}\,(\alpha\cdot a_{i})\cdot x^{i}$

Hence, polynomials are closed with respect to multiplication.

Find the area of this sector

slavikrds [6]

Answer:

1492.885

Step-by-step explanation:

the whole circle has 360° and an area of pi*r² =pi*24²=pi* 576

for 360° and A=pi*576

for 360-63= 297° and A= (297*576*pi) / 360 = 1,492.885 m²
