Consider the following polynomial expression: 4x^5-16x^2+13x^8. Part A: Write the polynomial expression in standard form.

zavuch27 [327]

Answer:

13x^8 + 4x^5 - 16x^2

Step-by-step explanation:

Standard form is just rearranging each group of numbers so that the group with the most exponents on the variables is at the beginning. So it's basically least to greatest but with exponents. Hope this helped!

Thaddeus wants to cover an area around a pond with natural slate stone. If the cost of the slate is $6.50 per square foot, how m

igomit [66]

Answer:

Cost of slate path using π: $980.18 (nearest cent)

Cost of slate path using π = 3.14: $979.68

Step-by-step explanation:

<u>Formula</u>

Area of a circle = πr² (where r is the radius)

First, calculate the area of the slate path by subtracting the area of the pond from the area of the larger circle.

Area of larger circle = π · 8² = 64π ft²

Area of pond (smaller circle) = π · 4² = 16π ft²

⇒ area of slate path = 64π - 16π = 48π ft²

If the cost of the slate is $6.50 per ft² then,

Cost of slate path using π:

⇒ 48π × $6.50 = $980.18 (nearest cent)

Cost of slate path using π = 3.14:

⇒ 48 × 3.14 × $6.50 = $979.68

Answer:

The direct distance between the birds is 12.64 miles.

Step-by-step explanation:

We have, one bird flew 12 miles west and another bird flew 4 miles north. It is required to find the direct distance between the birds. It means we need to find the resultant of two displacement. It can be given by :

$d=\sqrt{12^2+4^2} \\\\d=12.64\ \text{miles}$

So, the direct distance between the birds is 12.64 miles.

I need to find the overall answer and explanation of how to get it

mixas84 [53]

Okay this one is simple once when you get an understanding of what they are asking. First divide the numerators by the denominators. 2/5=0.4 this is terminating because there are no numbers after it ends at 4. 7/45 is 0.15555556... this is repeating because it keeps on going. 5/99 is 0.05050505... repeating. Lastly 27/250 is 0.108 this is terminating because it stops. :) Hope this helps.
