Answer:

Step-by-step explanation:

Solving For V.

2v=−10x

You need to divided both sides by 2.

2v /2 = −10x /2

v = −5x

Answer:

v = −5x

PLEASE HELP ME I AM HORRIBLE AT TRIGONOMETRY!!! TRIANGLES ARE SO HARD!!!

OleMash [197]

Answer:

A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.

(this may be more of an architect's job, as they are the ones that design the houses)

or

An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.

A cable company wants to provide cell phone service for residents on an island. The function for the cost of laying the cable fr

laila [671]

Answer:

C) domain: all real numbers greater than or equal to 0

range: all real numbers greater than or equal to 13,000

Step-by-step explanation:

We have, the function for the cost of laying cable is given by,

$c(x)= 6500\sqrt{x^2+4}$ , where x is the length of the cable (in feet).

As, 'x' represents the length of the cable.

We have that, the value of x cannot be negative.

So, x ≥ 0.

Since, the domain of $c(x)= 6500\sqrt{x^2+4}$ is the set of points where $x^2+4\geq 0$ and we have that x ≥ 0.

Thus, the domain is 'Set of all real numbers greater than or equal to 0'.

Now, we substitute x= 0 in $c(x)= 6500\sqrt{x^2+4}$ .

i.e. $c(0)= 6500\sqrt{0^2+4}$

i.e. $c(0)= 6500\sqrt{4}$

i.e. $c(0)= 6500\times 2$

i.e. c(0) = 13000.

So, we get that the vertex point of the function is (0,13000).

Thus, the range is 'All real numbers greater than or equal to 13,000'.

All property tax in Wyoming is based on the assessed value of the property being taxed. For county revenue, the tax rate cannot

omeli [17]

Answer:

The property tax is <u>$1008</u>.

Step-by-step explanation:

Given:

All property tax in Wyoming is based on the assessed value of the property being taxed.

The assessed value of a hotel is $84,000.

Tax rate is 1.2%.

Now, to find the property tax.

Property tax = Tax rate of the property assessed value.

$Property\ tax =1.2\%\ of\ \$84,000.$

$Property\ tax=\frac{1.2}{100}\times 84000.$

$Property\ tax=\frac{100800}{100}$

$Property\ tax=\$1008.$

Therefore, the property tax is $1008.

In parallelogram ABCD, m Find m

Nuetrik [128]

Answer:

The angle C measures 120 degrees.

Step-by-step explanation:

For a polygon of n sides, the sum of internal angles, in degrees is given by:

$S = (n-2) \times 180$

Parallelogram

4 sides, so

$S = (4-2)*180 = 360$

Two pairs of equal angles

B and D measure 60

A and C measure x. So

$2x + 2*60 = 360$

$2x = 240$

$x = \frac{240}{2}$

$x = 120$

The angle C measures 120 degrees.
