Problem 1

Answer:

  1. The square root of the <u>   expression   </u> of the <u>   difference   </u> of <u>   x^2   </u>  and 11.
  2. The <u>   quotient   </u> of <u>   2   </u> times a number and -1
  3. The <u>   sum   </u> of the <u>   square root   </u>of two times a number and 11.

------------

Explanation:

The term "difference" is the result of subtraction. We're subtracting the x^2 and 11. Then applying the square root to the result.

Question 2 has the blanks filled correctly.

For the last sentence, we have a sum of the terms \sqrt{2x} and 11.

===========================================================

Problem 2

Answer:

The value of an algebraic expression depends on its <u>   variables   </u>

  1. Substitute the known value for each variable.
  2. Simplify using the <u>   order   </u> of <u>   operations   </u>
  3. Use the work to answer any word problems related to the expression.

------------

Explanation:

The variables are placeholders for numbers

So for instance, saying x+5 is like saying "some unknown number plus 5".

We could replace it with something like x = 10 to get x+5 = 10+5 = 15

Once the variable is replaced, you use the order of operations PEMDAS (some books refer to it as BODMAS).

If you add the lengths of the focal radii of an ellipse, what other value will you produce?
ss7ja [257]

Equation of an ellipse

→having center (0,0) , vertex ((\pm a ,0) and covertex (\pm b ,0) and focus (\pm c ,0) is given by:

\frac{x^2}{a^2} + \frac{y^2}{b^2}=1

As definition of an ellipse is that locus of all the points in a plane such that it's  distance from two fixed points called focii  remains constant.

Consider two points (a,0) and (-a,0) on Horizontal axis of an ellipse:

Distance from (a,0) to (c,0) is = a-c = F_{1}

Distance from (-a,0) to (c,0) is = a + c = F_{2}

F_{1} + F_{2} = a -c + a +c

          = a + a

        = 2  a  →(Option A )

A bakery sells 2 croissants for $3 they sold 31 croissants on Monday, how much money did they make
Alisiya [41]
Since 2 croissants = $3 we can work out that 1 croissant = $1.50

Multiply $1.50 by 31 and we get $46.50

Therefore 31 croissants is $46.50
