Answer:

the average change in stock prices over the two days is -155

Step-by-step explanation:

= (-One day points - second day points) ÷ number of days

= (-250 points - 60 points ) ÷ 2 days

= -310 points ÷ 2 days

= -155

Hence, the average change in stock prices over the two days is -155

We simply applied the above formula so that the average change could come

Answer:xy^2+3x^2y;\text{  -24}

Explanation:

The given expression is:

xy+3xy^2-2xy+3x^2y-2xy^2+xy

Combine like terms

xy+xy-2xy+3xy^2-2xy^2+3x^2y

Simplify the resulting expression

\begin{gathered} 2xy-2xy+3xy^2-2xy^2+3x^2y \\  \\ xy^2+3x^2y \end{gathered}

Substitute x = 3 and y = -1 into the simplified expression

\begin{gathered} xy^2+3x^2y \\  \\ 3(-1)^2+3(3)^2(-1) \\  \\ 3(1)+(-27) \\  \\ 3-27 \\  \\ =-24 \end{gathered}

Find the measure of Angle 1.
BartSMP [9]

Answer:

85°

Step-by-step explanation:

  • Angles in a triangle add up to 180°.
  • 40° + 55° = 95° - This means that there is already 95° in the triangle
  • To find the missing angle (angle 1) we need to do 180 - 95 which is 85°.

Hope this helps!

27x³ – 108x² + 144x – 64

Step-by-step explanation:

(3x – 4)³

(3x – 4) × (3x – 4) × (3x – 4)

(9x² – 12x – 12x + 16) × (3x – 4)

(9x² – 24x + 16) × (3x – 4)

27x³ – 36x² – 72x² + 96x + 48x – 64

27x³ – 108x² + 144x – 64

Thus, The answer is 27x³ – 108x² + 144x – 64
