For the function defined by y = 1/x4, y varies inversely as what quantity
gregori [183]

ANSWER

y varies inversely as x exponent 4.

EXPLANATION

The inverse variation equation is given as:

y =  \frac{1}{ {x}^{4} }

We can see that there is an inverse relation between the quantity y and x.

If the it were y =  \frac{1}{ {x}^2 }, we say y varies inversely as the square of x.

Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.

What is the domain of y=cot x?
MissTica

We have to find the domain of y = cotx

We know that cotx = cos x / sinx

And also when sinx becomes zero cotx becomes undefined

And again we know that value of cosx and sinx can be between -1 to 1

But value of cotx can lie in between -∞ to +∞

Just for example cot30 is cos30 / sin30

= √3/2/1/2 = √3

Therefore domain of cotx is x

x ∈ R , x ≠ πn for any integer n

Please help!!!! will mark brainlest

Answer: B. 84 in²

Step-by-step explanation:

Divide the area into two regions: a rectangle and a trapezoid (depicted in the attached photo).

Find the area of the rectangle:

Area of a rectangle=length*width

Area of rectangle=(5 in)( 10 in)

Area of rectangle=50 in²

Next, calculate the area of the trapezoid:

Area of trapezoid=\frac{h(b_{1} +b_{2}) }{2}

h=10 in-6 in

h=4 in

b_{1} =15 in

b_{2} =15 in-5 in

b_{2} =10 in

Area of trapezoid=\frac{4in(7 in+10in)}{2}

Area of trapezoid=\frac{4(17in^{2})  }{2}

Area of trapezoid=\frac{68in^{2} }{2}

Area of trapezoid=34in^{2}

Add the area of the trapezoid to the area of the rectangle to find the total area: 50 in²+34 in²=84 in²
