Answer:

Option C and D that is y= tan x and y= cot x

Step-by-step explanation:

The range is the values of y means the values that y can take in a function:

So, range of tan x and cot x are all real numbers.

Period of  tan x is \pi

Period of cot x is \pi

Option A and B that is secx and csc x are discarded

Answer with explanation:

Given a function, y=f(x)

The Set of values that ,x can take for which y is defined is called domain of the function.

And,the set of values that ,y can take for which x ,is defined is called range of function.

For example:→Consider the function, y=x²

→y is defined for all values of x,so Domain is set of real numbers.→(-∞,∞)

→x is defined for positive values of y,so range of this function is [0, ∞).

A:→ y =sec x

Range =(-∞,-1]∪[1,∞)

B: →y=Cosec x

Range =(-∞,-1]∪[1,∞)

C:→y=tan x

Range =(-∞,∞)

D:→y=cot x

Range=(-∞,∞)

→→Option C and D⇒Tan x and Cot x, are trigonometric function ,whose range are set of all Real Numbers.

Let R be the region enclosed by the y-axis, the line y=1 and the curve y=x^3. A solid is generated by rotating R about the line
scZoUnD [109]

Answer:

The volume of the solid is 19.\overline{142857} unit³

Step-by-step explanation:

The given function is y = x³

The solid is created by revolving R about the line y = 1

We have that when y = 1, x = 1

Taking the end point as x = 2, we have the volume given by the washer method as follows;

V = \pi \cdot \int\limits^a_b {\left( [f(x)]^2 - [g(x)]^2 \right)} \, dx

Where;

a = 1, and b = 2, we have;

g(x) = 1

V = \pi \cdot \int\limits^{2}_1 {\left( [x^3]^2 - [1]^2 \right)} \, dx  = \pi \cdot \left[\dfrac{x^7}{7} + x \right]_1^{2} = \pi \cdot \left[\dfrac{2^7}{7} +2 -\left( \dfrac{1^7}{7} + 1\right)\right] =19\dfrac{1}{7}

The volume of the solid, V = 19\dfrac{1}{7} unit³ = 19.\overline{142857} unit³

aleksandrvk [35]

Answer: Type I error

Step-by-step explanation:

A type 1 error is also referred to as the false positive and it is when a true null hypothesis is incorrectly rejected by the researcher.

On the other hand, type II error which is also refered to as the false-negative is when a null hypothesis which is false is failed to be rejected by the researcher but rather accepted.

Based on the information given in the question, since the data leads to the rejection of the null hypothesis such was later found out to be true, then a type I error has occured.

The coordinates of the image of triangle are transformation are X = (1,3), Y = (5,-3) and Z = (-1, -7)

<h3>How to determine the transformation?</h3>

From the figure, the coordinates of the triangle are:

A = (-1, -1)

B = (1, 2)

C = (-2,4)

The transformation rule is given as:

\triangle XYZ = T_{ < 3,1 > }(R_{x-axis}(D_2(\triangle ABC)))

This means that, we start by dilating the triangle by a scale factor of 2.

So, we have:

A' = (-2, -2)

B' = (2, 4)

C' = (-4,8)

Next, we rotate the triangle across the x-axis

So, we have:

A'' = (-2, 2)

B'' = (2, -4)

C'' = (-4,-8)

Lastly, we translate the triangle by (x + 3,y + 1) to get the triangle XYZ

So, we have:

X = (1,3)

Y = (5,-3)

Z = (-1, -7)

See attachment for the image of the transformation
