Simplify the expression

Travka [436]

Answer:

$Hi, ~I'm ~beinggreat78,~ and~ am~ here~ to~ help~ you.$

The answer is D. Tanɵ. But why? Let's break it down. Tan pi + theta in the base equation should look like this...

$\frac{tan\pi+ tanTheta}{1 - tan\pi * tanTheta}$

We now have to simplify this expression. Let's do that.

$tan(\pi) = \frac{sin\pi }{cos\pi } = \frac{0}{-1} = 0$

Now that we have broken this problem into simpler fragments, we have to put it all together, The final equation should look like the one below!

$tan(\pi + Theta) = \frac{0 + tanTheta}{1 - 0} = tanTheta$

With that information, we have solved the problem, your final answer is tanɵ

The linear momentum is a constant when the mass varies inversely of the velocity. If the velocity is 16 meters per second and th

kiruha [24]

Answer:

the weight for an object with a velocity of 12 meters per second is 600 kilograms

Step-by-step explanation:

The linear momentum of an article is : p = mv

Where p = Momentum

m = mass

v = velocity

The velocity is 16 meters per second and the object weighs 450 kilograms

So, $p = 450 \times 16$

We are supposed to find the weight for an object with a velocity of 12 meters per second

So, p = 12m

We are given that the linear momentum is a constant when the mass varies inversely of the velocity.

So, $450 \times 16 = 12 \times m\\\frac{450 \times 16}{12}=m\\600=m$

Hence the weight for an object with a velocity of 12 meters per second is 600 kilograms

If a 45 45 90 triangle has the hypothenuse of 10 what would the legs x and y be

melamori03 [73]

Answer:

Step-by-step explanation:

When working with 45-45-90 triangles the hypotenuse is the same as the other legs multiplied by root 2. Therefore if you need to find the legs and already have the hypotenuse, divide the hypotenuse by root 2.

10/ sqrt(2) = 7.1 is the rounded answer.

to double check your work just multiply 7.1 by the square root of 2 and you'll get <em>close</em> to 10. (because the answer is rounded and not exact.)

David has 36 apple and pear trees in his gardens. If he plant 4 more apple trees, he will have the same amount of apple and pear

amm1812

Answer:

16 apples, 20 pears

Step-by-step explanation:

36+4=40

So 40/2= 20 or an even amount of both apples and pears

20-4= 16 ~Original amount of apples

36-16=20 ~Amount of pears
