Answer:

x ≈ 80.4

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan15° = \frac{opposite}{adjacent} = \frac{x}{300} ( multiply both sides by 300 )

300 × tan15° = x , then

x ≈ 80.4 ( to the nearest tenth )

(2x^3+6x-1)+(3x^2-7x)
sattari [20]

For this case we must simplify the following expression:

(2x ^ 3 + 6x-1) + (3x ^ 2-7x)

We eliminate the parentheses taking into account that:

+ * + = +\\+ * - = -

So, we have:

2x ^ 3 + 6x-1 + 3x ^ 2-7x =

We add similar terms taking into account that:

Different signs are subtracted and the sign of the major is placed:

2x ^ 3 + 3x^2-x-1

Answer:

2x ^ 3 + 3x^2-x-1

77julia77 [94]

Answer:

Expanded form : 300,000 +80,000 +2000 +700 +6.

Step-by-step explanation:

Given  : 382,706.

To find : Write this number in expanded form.

Solution : We have given  382,706.

We can  see 3 is at hundred thousand place = 300,000

8 is at ten thousand place = 80,000.

2 is at thousand place  = 2000.

7 is at hundred place  = 700.

6 is at ones place = 6

Then

Expanded form : 300,000 +80,000 +2000 +700 +6.

Therefore, Expanded form : 300,000 +80,000 +2000 +700 +6.

In AEFG, F = 61 inches, ZF=79º and ZG=34°. Find the length of g, to the nearest<br> 10th of an inch.
DENIUS [597]

Answer:

  g ≈ 34.7 in

Step-by-step explanation:

The law of sines is useful for this:

  f/sin(F) = g/sin(G)

Multiplying by sin(G), we have ...

  g = f·sin(G)/sin(F) = (61 in)·sin(34°)/sin(79°)

  g ≈ 34.7 in
