I’m having problems doing questions 1-6, which ask to write the numbers in scientific and decimal notation, which I have no idea

of. Btw this is maths and we’re learning about Scientific Notation. If someone knows how to do these, it would be very much appreciated. Thanks

OX and OY are two straight lines which intersect at an acute angle of 60°. OX = 4.5cm and OY = 5cm . The point M is on OX such t
Neko [114]

Therefore the point P is at 3.46 cm from O and it lies on the angle bisector of ∠XOY

<h3>What is an Angle Bisector ?</h3>

The ray that bisects the angle into half is called Angle Bisector.

It is given that ∠XOY = 60 degree

the length of OX = 4.5 cm

OY =5 cm

The point M is on OX such that

OM = 2 MX

so The M is at 3 cm from O

The point P lies in the acute angle such that the distance between point P and OX and OY is always same and at 3 cm from M

According to the angle bisector theorem converse states that if a point is in the interior of an angle and is at equal distance from the sides  then it lies on the bisector of that angle.

As it can be seen from the image that a point equidistant from the rays , at 3 cm from M will be at

By Pythagoras Theorem

3² +3² = OP²

OP = 2\sqrt{3} = 3.46 cm from O

What are the terms in the expression 2x−4y+8 ?
rodikova [14]

Answer:

<u>The correct answer is D. 2x, -4y, and 8.</u>

Step-by-step explanation:

The concept of the terms of an equation is used for the monomials of each member participating in the equation. In Mathematics we distinguish between two types of terms:  

1. The terms in x: when the terms are accompanied by a literal.

2. The independent terms: when the terms are constituted by numerical elements.

In regina, saskatchewan, the average mid-afternoon temperature in january is -12.6°C.The average mid afternoon temperature in ju
Andrews [41]

Finding the difference between the two temperatures, it is found that Regina is 38.7ºC degrees colder in January than in July.

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

  • The mid-afternoon temperature in January is of -12.6ºC.
  • In July, it is of 26.1ºC.
  • The difference of the temperatures is given by:

26.1 - (-12.6) = 26.1 + 12.6 = 38.7

From the difference of 38.7ºC, there are two interpretations:

  • Regina is 38.7ºC degrees colder in January than in July.
  • Regina is 38.7ºC degrees warmer in July than in January.
