Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1? f(x) = (x – 2i)(x – 3i) f(x) =
kykrilka [37]

Answer:

P(x)=(x-2i)(x-3i)

Step-by-step explanation:

Build a Polynomial Knowing its Roots

If we know a polynomial has roots x1, x2, ..., xn, then it can be expressed as:

P(x)=a(x-x1)(x-x2)...(x-xn)

Where a is the leading coefficient.

Note the roots appear with their signs changed in the polynomial.

If the polynomial has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1, then:

P(x)=1(x-2i)(x-3i)

\mathbf{P(x)=(x-2i)(x-3i)}

A circular field has arey 144001 square feet.<br> What is the radius of the field?
anzhelika [568]

Answer:

about 214.1

Step-by-step explanation:

Since pi r squared is the formula for a circle's area, you would do the opposite. First, you would divide 144001 by pi which is about 45,836.94. Then, you would find the square root of that which is about 214.1.

Drag each tile to the correct box. Order the expressions from least value to greatest value. ​
wel

Answer:

\frac{5}{-1.6}

Step-by-step explanation:

We will solve the given expressions and find the answer in decimals.

1). 5\frac{6}{15}+(-2\frac{4}{5}) = 5\frac{2}{5}-2\frac{4}{5}

                   = 5.4 - 2.8

                   = 2.6

2). -3\frac{3}{10}-(-\frac{7}{20})=-3\frac{3}{10}+\frac{7}{20}

                           = -3.3 + 0.35

                           = -2.95

3). \frac{5}{-1.6}=-\frac{5}{1.6}

      = -3.125

4). (-4.5) × (-2.3) = 10.35

Solution of the expressions in the increasing order will be,

-3.125 < -2.95 < 2.6 < 10.35

\frac{5}{-1.6}

Fiction Cruiseline offers three ways to exercise on their cruise ships. 73 of the 86 passengers participated in at least one met
lutik1710 [3]

Answer:

The probability of exercise in cruise ships = 73

Step-by-step explanation:

Let A be the probability of rock climbing

Let B be the probability of ice skating

Let C be the probability of fitness center

P(A) = 36, P(B) = 44, P(C) = 27

P(A ∩ B) = 14, P(A ∩ C) = 11, P(B ∩ C) = 9

P(A ∩ B ∩ C)=0

By formula,

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B) − P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C).

Substituting the values in the above formula,

P(A ∪ B ∪ C) = 36 + 44 + 27 - 14 - 11 - 9 + 0

  = 107 - 14 - 11 - 9

P(A ∪ B ∪ C)  = 73
