Answer:

Step-by-step explanation:

If you put x+x+x+x into a calculator, then you get a line that is equivalent to 4x. Other than that, I can't really explain that any more.

Hope that this helps!

A soccer team played 160 games and won 65 percent of them. How many games did it win ? Please show work

galben [10]

To find the percent of games the soccer team won, you would do 160 multiplied by 0.65, because if you were to convert the 65% into a decimal, you would get 0.65. Notice the key word, "of". This refers to multiplication. So when doing 160*0.65, you get 104 games won. Therefore the soccer team won 104 of their games.

Hope this helps! :D Feel free to ask more questions, or ask me questions about my explanation.

According to the Rational Root Theorem, which number is a potential root of f(x) = 9x8 + 9x6 – 12x + 7?

bogdanovich [222]

Answer:

Seven-thirds

Step-by-step explanation:

The give equation is $f(x)=9x^8+9x^6-12x+7$ .

The leading coefficient is 9

The constant term is 7

According to the rational root theorem, the ratio of factors the constant terms to that of the coefficient of the leading term are all possible rational roots of the given polynomial.

Base on this theorem, $\frac{7}{3}$ or seven thirds is a potential root because the numeration is a factor of 7 and the denominator is a factor of 9.

A circle of radius of 4 inches has an arc length of 5.8 inches. Find the measure of the central angle.

kondor19780726 [428]

<h3>SOLUTION : </h3>

The radius of the circle is 4 inch and has an arc length of 5.8 inches . We know that if the central angle is 360° then the arc length is $2\pi r$ . Similarly when angle is theta ,

$\implies Arc = radius \times \theta$

Now substitute respective values , from the given data ,

$\implies 5.8 inch = 4inch * \theta \\\\\implies 0.14 m = 0.1 * \theta \\\\\implies \boxed{\red{\theta \approx 1.4 \ rad }}$

This is our required answer!
