Answer:

\boxed {\boxed {\sf x= -13}}

Step-by-step explanation:

We are asked to solve the following one-step equation.

-104 = 8x

We solve the equation by solving for x. We must isolate the variable by performing the inverse operation.

x is being multiplied by 8 (8x = 8*x). The inverse operation of multiplication is division. Divide both sides of the equation by 8. This eliminates the 8 on the right side of the equation so only x remains.

\frac {-104}{8}= \frac{8x}{8}

\frac {-104}{8}= x

-13=x

We can check our answer by substituting it back into the original equation.

-104= 8x

-104= 8(-13)

-104= -104

This checks out, so we know our answer is correct and x is equal to <u>-13.</u>

Answer:

See below in bold.

Step-by-step explanation:

Ship's vector:

Horizontal component = 30 cos 30  = 25.98.

Vertical component = 30 sin(-30) = -15.

So it is <25.98, -15).

The current's vector:

Horizontal component =  5 sin 20 = 1.71.

Vertical component = 5 cos 20 = 4.7.

So it is <1.71, 4.7>.

You look down at an object on the ground. If your eyes are
wolverine [178]

Answer:

We can think of this as a triangle rectangle.

We know that you eyes are 55ft above the ground, this can be one cathetus.

We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.

Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.

So we only know one angle and the opposite cathetus to this angle, then we can use the relation:

Sin(θ) = (opposite cathetus)/(hypotenuse)

Then if we use this equation, we will get:

Sin(50°) = 55ft/hypotenuse

hypotenuse = 55ft/sin(50°) = 71.8 ft

This means that the distance between you and the object is 71.8 ft.

Hey can anyone pls help me in this real quick!!!!
Bas_tet [7]

Answer:

1.The Pythagorean theorem is used in football by telling the defender how much is necessary to run.For example the ball carrier is heading for the end zone 40 yards away.The defender stands 30 yards away and needs to defend him. Pythagorean theorem states A^2 +B^2=C^2.so comparing to Pythagorean theorem these sides are the legs of the triangle. forming 90 degree angle. The distance the defender need to run is the hypotenuse. So (40^2)times(30^2)=50^2.

2. It would be important for a football player to understand the Pythagorean theorem because that way they can now the direction there running, and angle defender needs to run, the speed need to use to outrun opponent, and so that the defender can now what distance to run in a the same time it takes the ball carrier to run to the same place. This can make a difference between a touchdown or a game saving tackle.
