If 154 people do both activities, then 196-154=42 people ski but don't snowboard.

If 42 people don't snowboard, then 200-42=158 people snowboard.

200 - 196(ski) = 4 snowboard

196(ski) - 154(both) = 42 ski

154(both) - 42(ski) = 112 snowboard

112 + 4 = 116 snowboard

The answer is 116 ... I think...

Determine whether the given function is a solution to the given differential equation.
lesantik [10]

Given :

A function , x = 2cos t -3sin t               .....equation 1.

A differential equation , x'' + x = 0      .....equation 2.

To Find :

Whether the given function is a solution to the given differential equation.

Solution :

First derivative of x :

x'=\dfrac{d(2cos t - 3sin t)}{dt}\\\\x'=\dfrac{d(2cost)}{dt}-\dfrac{(3sint)}{dt}\\\\x'=-2sint-3cost

Now , second derivative :

x''=\dfrac{d(-2sint-3cost)}{dt}\\\\x''=-\dfrac{d(2sint)}{dt}-\dfrac{d(3cost)}{dt}\\\\x''=-2cost+3sint

( Note : derivative of sin t is cos t and cos t is -sin t )

Putting value of x'' and x in equation 2 , we get :

=(-2cos t + 3sin t ) + ( 2cos t -3sin t )

= 0

So , x'' and x satisfy equation 2.

Therefore , x function is a solution of given differential equation .

Hence , this is the required solution .

Simplify using the laws of exponents: x4 x6 =
aksik [14]
Hey there!
The law of multiplication of exponents is:
a^b * a^c = a^b+c
Therefore, we have:
x^4 * x^6= x^4+6 = x^10
Hope this helps!

The bisector of an obtuse angle forms:acute anglesright anglesobtuse anglesstraight angles
Lerok [7]
It forms an acute angle.

The obtuse angle is greater than 90 degrees but less than180 degrees. So if a bisector is introduced, the resulting angle is acute. An acute is less than 90 degrees.
