(7w3-4w+3)+(5w3-3w-3)

1 answer:

7 0

That is a simple polynomial addition:
(7w3-4w+3)+(5w3-3w-3)
= (7w^3 - 4w + 3) + (5w^3 - 3w - 3)
= 7w^3 - 4w + 3 + 5w^3 - 3w - 3
= 12w^3 - 7w
= w(12w^2 - 7)

The angle of deperession of aPt A, as measured form the top of

lara [203]

Answer:B

Step-by-step explanation:

Given

Height of building $h=30\ m$

Angle of depression $\theta =45^{\circ}$

Suppose distance of Point A from base of building be $x$

From diagram we can write

$\Rightarrow \tan \theta =\dfrac{h}{x}$

$\Rightarrow \tan (45^{\circ})=\dfrac{30}{x}$

$\Rightarrow 1=\dfrac{30}{x}$

$\Rightarrow x=30\ m$

So, point A is $30\ m$ from base of building

What is a postulate?

zloy xaker [14]

Answer:

A statement, also known as an axiom, which is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived.

Step-by-step explanation:

The Addition Postulate: If you have one apple and Sally has one apple, when you both add the same quantity to your existing number of apples, you'll still have the same number of apples. Using algebra, the postulate states:

If x = y, then x + 4 = y + 4

The Subtraction Postulate: If you have ten apples and Sally has ten apples, when you both subtract the same quantity of apples from your existing number of apples, you'll still have the same number of apples.

If x = y, then x - 3 = y - 3

Without being repetitive, these same principles apply to both multiplication and division.

The Multiplication Postulate: If x = y, then x * 3 = y * 3

The Division Postulate: If x = y, then x / 7 = y / 7

Solve the equation on the interval [0, 2π). √2 cos x - 1 = 0

jek_recluse [69]

Answer:

Step-by-step explanation:

$\sqrt{2} cos x-1=0\\cos x=\frac{1}{\sqrt{2} } =cos (\frac{\pi }{4} ),cos (2\pi -\frac{\pi }{4} )\\cos x=cos(2n\pi +\frac{\pi }{4} ),cos(2n\pi +\frac{7\pi }{4} )\\x=2n\pi +\frac{\pi }{4} ,2n\pi +\frac{7\pi }{4} \\n=0\\x=\frac{\pi }{4} ,\frac{7\pi }{4}$
