Which of the following functions have a vertical asymptote for values of θ such that cos θ = 1? Select two answers.

1 answer:

3 0

Well costheta=1, at 0, 2pi,...
knowing this we can exclude the first two as the are not undefined anywhere.
tan is sin/cos, at 0 sin is also 0 so it becomes 0/1 which is 0, not undefined.
sec is1/cos, cos is 1, this is just 1
csc is 1/sin, sin is 0, 1/0 is undefined, meaning there will be an asymptote
cot is cos/sin, this is again 1/0, so it is also an asymptote
The last two answers are the ones you want

The area of a circular field is 154msqu. What is the perimeter of the field?(pi=22/7) 44 49 88 176

OLga [1]

Answer:

44m

Step-by-step explanation:

A = $\pi$ r² = 154

= 22/7 * r² = 154

= r² = 154 * 7/22

= r² = 49

= r = √49

= r = 7m

Perimeter of circle = 2 $\pi$ r

= 2 * 22/7 * 7

= 44/7 * 7

= 44 m

In Exercise, find the derivative of the function. y = ln(3 + x2)

erastovalidia [21]

Answer: $\dfrac{2x}{3 + x^2}$

Step-by-step explanation:

We know the property of derivative: $\dfrac{d}{dx}(\log (x))=\dfrac{1}{x}$

Given function : $y=\ln(3 + x^2)$

Differentiate both sides with respect to x , we get

$\dfrac{dy}{dx}=\dfrac{d}{dx}(\ln(3 + x^2))$

$\Rightarrow\ \dfrac{dy}{dx}=\dfrac{1}{3 + x^2}\cdot\dfrac{d}{dx}(3 + x^2)$ [By Chain rule]

$\Rightarrow\ \dfrac{dy}{dx}=\dfrac{1}{3 + x^2}\cdot(0+2x)$

[Since $\dfrac{d}{dx}(a)=0$ , where a is scalar and $\dfrac{d}{dx}(x^n)=n(x)^{n-1}$ ]

$\Rightarrow\ \dfrac{dy}{dx}=\dfrac{2x}{3 + x^2}$

Hence, the derivative of the given function is $\dfrac{2x}{3 + x^2}$ .

1. the pitcher is full because it can hold 1 liter, which is 1000ml and 500+400=900 so there would be 100ml before it would overflow.
2. Grant uses 3000ml of ginger, since 3g=3000ml.
3.<
4.>
5.=
6. 4L = 4000ml
9L = 9000ml
7. 6g = 6000mg
11g = 11000mg
