expeople1 [14]

Answer:

I think the answer is

$x = \frac{9}{7}$

Step-by-step explanation:

Reason :

$4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7}$

Therefore

$x = \frac{9}{7}$

Can you help me please

alexira [117]

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

|v|=38

Ф = 120°

<u>Finding the horizontal component</u>

The horizontal component can be obtained using the formula

Vx = |v| cos Ф

= 38 cos 120°

= 38 (-0.5)

= -19

Thus, the horizontal component is:

Vx = -19

<u>Finding the vertical component</u>

The vertical component can be obtained using the formula

Vy = |v| sin Ф

= 38 sin 120°

= 38 (0.86)

= 32.68

Thus, the vertical component is:

Vy = -19

A vector 'v' with magnitude |v| and direction Ф can be written as:

v = |v| cos Ф i + |v| sin Ф j

As

|v|=38

Ф = 120°

Thus, the vector is

v = 38 cos 120° i + 38 sin 120° j

or

v = -19 i + 32.68 j

Find the Circumference of a circle with a Diameter of 9 inches Group of answer choices 9 pi inches 9 pi inches^2 9 pi inches^3 1

katen-ka-za [31]

Answer: $9\pi\ in.$

Step-by-step explanation:

Given

The diameter of a circle is $d=9\ in.$

So, the radius is $r=\frac{d}{2}=4.5\ in.$

The circumference is given by $2\pi r$

Insert the values

$\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.$

Thus, the circumference of the circle is $9\pi\ in.$
