What is the equation?

X2+11x+30 what does x2 mean
Alexxandr [17]

x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.

Which graph shows the solution to this system of linear inequalities?
galben [10]

Answer:

C

Step-by-step explanation:

Since all the graphs have the same line, you’re just looking for the correct shaded region. Since for both equations you want the shaded region to be less than the line, answer c solves the inequality.

Yuri’s sister Karina is 12 years old. In the equation below, y represents Yuri’s age in years.
OLga [1]
In the given equation above, it can be deduced that 2 subtracted from 3 times Yuri's age is equal to the age of Karina which was given to be twelve. This statement is similar to that which is given in the choice number four. Thus, the answer is D.

use the picture to write each ratio as a simplified fraction (how are you going to find the length of the third side?) show your
Butoxors [25]

Answer:

<h3>See below</h3>

Step-by-step explanation:

to figure out the ratios we must figure out the length of <u>hypotenuse</u> first to do so we can consider <u>Pythagoras</u><u> theorem</u> given by

\displaystyle  {a}^{2}  +   {b}^{2}  =  {c}^{2}

\displaystyle \implies c =  \sqrt{ {a}^{2} +  {b}^{2}  }

substitute:

\displaystyle c =  \sqrt{ {12}^{2} +  {9}^{2}  }

simplify squares:

\displaystyle c =  \sqrt{ 225 }

simplify square root:

\displaystyle c = 15

now recall that,

  • \displaystyle  \sin( \theta)  =  \frac{opp}{hypo}
  • \displaystyle\cos( \theta)  =  \frac{adj}{hypo}
  • \displaystyle   \tan( \theta)  =  \frac{opp}{adj}

the ratios with respect to angle w given by

  • \displaystyle  \sin( W)  =  \frac{12}{15}  =  \frac{4}{5}
  • \displaystyle  \cos(W)  =  \frac{9}{15}  =  \frac{3}{5}
  • \displaystyle  \tan( W)  =  \frac{12}{9}  =  \frac{4}{3}

the following ratio with respect to angle X

  • \displaystyle  \sin(X)  =  \frac{9}{15}  =  \frac{3}{5}
  • \displaystyle  \cos(X)  =  \frac{12}{15}  =  \frac{4}{5}
  • \displaystyle  \tan( X)  =  \frac{9}{12}  =  \frac{3}{4}
