Find the area of a circle with a radius of 7.1 m to the nearest square unit.

Answers

Answer 1
Answer:

Answer:

158 m2

Step-by-step explanation:

A=πr2=π·7.12≈158.36769m²
Answer 2
Answer: To find the area you do pi r squared. 7.1 squared is 52.54. 52.54 X pi =165.06. The answer is 165.06 cm2.

5. What is a cubic polynomial function in standard form with zeros 1, –2, and 2? (1 point)= x3 + x2 – 3x + 4
= x3 + x2 – 4x – 2
= x3 + x2 + 4x + 4
= x3 – x2 – 4x + 4

Answers

Answer:

Option D is correct

The cubic polynomial function in standard form is :

x^3-x^2-4x+4

Step-by-step explanation:

Given the zeroes of the polynomial function 1 , -2 and 2.

i.e,   x = 1 , -2 and 2  where x is the zero of the polynomial function.

we can write this as

x - 1 = 0,

x + 2 = 0 or

x - 2 = 0  

(x - 1)(x + 2)(x - 2) =0  

Using identities (a+b)(a-b) =a^2-b^2

then;

(x-1)(x^2-4)=0

Multiply the first term of the first expression with second expression;

x (x^2-4) =x^3-4x

also,

Multiply the second term of the first expression with second expression;

1(x^2-4) = x^2 -4

Now, subtract x^3-4x and x^2 -4

we get;

x^3-4x-x^2+4

then, we have;

x^3-x^2-4x+4=0

Cubic function is any function of the form y = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants and a≠0

therefore, the given function is cubic function;

so, the cubic function f(x) = x^3-x^2-4x+4
Hello,

Answer D
(x-1)(x+2)(x-2)=(x-1)(x²-4)=x^3-x²-4x+4

Answers

Answer:

  D  Numbers that can be written as fractions

Step-by-step explanation:

A rational number is one that can be written as a ratio: a fraction with integer numerator and denominator.

__

The term "decimal" as used here is sufficiently non-specific that we cannot seriously consider it to be part of a suitable answer. A terminating or repeating decimal will be a rational number. A non-terminating, non-repeating decimal will not be a rational number.

While integers and whole numbers are included in the set of rational numbers, by themselves, they do not constitute the best description of the set of rational numbers.
