\bf 4sin(\theta)+1=3\implies 4sin(\theta)=2\implies sin(\theta)=\cfrac{2}{4}
\\\\\\
sin(\theta)=\cfrac{1}{2}\implies sin^{-1}[sin(\theta)]=sin^{-1}\left( \cfrac{1}{2} \right)\implies \theta=sin^{-1}\left( \cfrac{1}{2} \right)

Find the product of (x − 5)2. (1 point) Group of answer choices x2 + 10x + 25 x2 − 10x + 25 x2 − 25 x2 + 25
Anuta_ua [19.1K]

Answer:

x^2 - 10x + 25

Step-by-step explanation:

Hello!

Expand the square using the Distributive Property.

<h3>Expand</h3>
  • (x - 5)^2
  • (x - 5)(x-5)

Distributive x - 5 to each factor

  • x(x - 5) -5 (x - 5)
  • x^2 - 5x - 5x+25
  • x^2 - 10x + 25

The answer is x^2 - 10x + 25.

We can also use a special binomial product formula.

Formula: (a - b)^2 = a^2 - 2ab + b^2

  • (x - 5)^2 = x^2 - 2(x)(5) + 5^2
  • (x - 5)^2 = x^2 - 10x + 25

We get the same answer both ways.

t hits the square dartboard shown below at a random point. Find the probability that the dart lands in the shaded circular regio
masha68 [24]

Given:

Required:

To find the probability that the dart land will be in the shaded region.

Explanation:

Area of the circle is given by the formula:

A=\pi r^2

Where r = radius

Thus the area of the circular region

\begin{gathered} =(3.14)\times(2)^2 \\ =3.14\times4 \\ =12.56\text{ square in.} \end{gathered}

The area of the square is given by the formula:

=(side)^2

Thus the area of the given square

\begin{gathered} =(6)^2 \\ =36\text{ square in.} \end{gathered}

The probability of an event is given by the formula:

P=\frac{number\text{ of possible outcomes}}{Total\text{ number of outcomes}}

The probability that the dart land will be in the shaded region

=\frac{Area\text{ of the shaded region}}{Area\text{ of the square}}

Thus probability

\begin{gathered} P=\frac{12.56}{36} \\ P=0.3488 \\ P=0.349 \end{gathered}

Final answer:

Thus the probability that the dart land will be in the shaded region is 0.349.
