Mathematics
1 answer:
BabaBlast [244]2 years ago
4 0

Answer:

∠ L ≈ 21.6°

Step-by-step explanation:

Using the Sine rule in the triangle

\frac{MN}{sinL} = \frac{LM}{sinN} , that is

\frac{34}{sinL} = \frac{42}{sin27} ( cross- multiply )

42 × sinL = 34 × sin27° ( divide both sides by 42 )

sinL = \frac{34sin27}{42} , then

∠ L = sin^{-1} ( \frac{34sin27}{42} ) ≈ 21.6° ( to the nearest tenth )

How does the value of 874.12 change if the decimal point is moved two places to the left?
Rashid [163]

Answer:

C

Step-by-step explanation:

When you move the decimal either to the right or the left, you change the value. To divide any number by 10, move the decimal point one place to the left. For example:  

0.7

7

70

700

7,000

So, for any decimal, when you move the decimal point one place to the right, you multiply that number by 10.

Which algebraic expression is equivalent to
poizon [28]
Hey there :)

( 2x⁵ - 3x⁴ + x² + 5x + 7 ) - ( - 4x⁵ - x⁴ - 3x² - 5x + 2 )

Let us combine like-terms
2x⁵ - ( - 4x⁵ ) - 3x⁴ - ( - x⁴ ) + x² - ( - 3x² ) + 5x - ( - 5x ) + 7 - 2

Minus and minus becomes plus
2x⁵ + 4x⁵ - 3x⁴ + x⁴ + x² + 3x² + 5x + 5x + 7 -2

6x⁵ - 2x⁴ + 4x² + 10x + 5

Your answer will be option A) 6x⁵ - 2x⁴ + 4x² + 10x + 5
