3858.

Define 1) factor 2 ) multiple, Given two examples of each

Answer»

$\huge\tt\fcolorbox{lavenderblush}{plum}{⌗Aŋʂwɛr♡༉}$

FACTOR - A factor divides a number completely without LEAVING any remainder.

➘ For example:-

30 ÷ 6 = 5, and there is no remainder. So, now 5 and 6 are the factors of 30.
10 ÷ 2 = 5, and there is no remainder. And so, 5 and 2 are the factors of 10.

Multiple - A multiple is the product that we get when one number is multiplied by another number.

➘ For example:-

4 × 5 = 20, here 20 is a multiple of 4 and 5.
2 × 6 = 12, here 12 is a multiple of 2 and 6.

In the figure ABC is a right angle triangle in which angle B is 90°BC = 6 cm, angle C is 60° then the length of AC is, A) 12cm D) 10cm

Answer»

Answer:12cm

Step-by-step explanation:

SINCE here only one side is given, then you have to consider sin,cos,TAN

sin cos tan

Opposite side Adjacent side Opposite side

Hypotenuse Hypotenuse Adjacent side

There is only one angle given here APART from the right angle.

Here, we have to find, AC (hypotenuse) and the side BC, which happens to be adjacent to 60 DEGREE is given.

The only trigonometry function which includes both Hypotenuse and Adjacent is cos.

cos 60 = Adjacent side

Hypotenuse

= 6cm

Value of cos 60 is 1/2

So, $\frac{1}{2}x = 6$

$x=$ 6 ÷ $\frac{1}{2}$

The function is defined by f(x)= 2xcube + 7xsquare+7x+2, find the linear factors of f(x) and sketch the curve of fx

Answer»

$\large\underline{\sf{Given- }}$

The function,

$\rm :\longmapsto\:f(x) = {2x}^{3} + {7x}^{2} + 7x + 2$

$\large\underline{\sf{To\:Find - }}$

1. The linear FACTORS of f(x)

2. The graph of f(x).

$\large\underline{\sf{Solution-}}$

Given function is

$\rm :\longmapsto\:f(x) = {2x}^{3} + {7x}^{2} + 7x + 2$

can be regrouped as

$\rm \: = \: \: ( {2x}^{3} + 2) + ( {7x}^{2} + 7x)$

$\rm \: = \: \: 2( {x}^{3} + 1) + 7( {x}^{2} + x)$

We know,

$\boxed{ \rm{ {x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2})}}$

So, using this identity, we get

$\rm \: = \: \: 2(x + 1)( {x}^{2} - x + 1) + 7x(x + 1)$

On taking ( x + 1 ) common, we get

$\rm \: = \: \: (x + 1)(2 {x}^{2} - 2x + 2 + 7x)$

$\rm \: = \: \: (x + 1)(2 {x}^{2} + 5x + 2)$

$\rm \: = \: \: (x + 1)(2 {x}^{2} + 4x + x + 2)$

$\rm \: = \: \: (x + 1)\bigg(2x(x + 2) + 1(x + 2)\bigg)$

$\rm \: = \: \: (x + 1)(x + 2)(2x + 1)$

HENCE,

$\boxed{ \bf \: { f(x) \: = \: (x + 1)(x + 2)(2x + 1) \: }}$

To sketch the graph of f(x).

Let assume that

$\boxed{ \bf \: { y \: = \: f(x) \: = \: (x + 1)(x + 2)(2x + 1) \: }}$

Point of intersection with x - axis.

On x - axis, y = 0

$\rm :\longmapsto\:(x + 1)(x + 2)(2x + 1) = 0$

$\bf\implies \:x = - 1, \: - 2, \: - \: \dfrac{1}{2}$

Hence, Point of intersection with x- axis are

$\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf - 1 & \sf 0 \\ \\ \sf - 2 & \sf 0 \\ \\ \sf - \dfrac{1}{2} & \sf 0 \end{array}} \\ \end{gathered}$

Point of intersection with y - axis

On y - axis, x = 0

$\rm :\longmapsto\:y = (0 + 1)(0 + 2)(2(0) + 1)$

$\rm :\longmapsto\:y = 1 \times 2 \times 1$

$\bf\implies \:y = 2$

So, point of intersection with y axis is ( 0, 2 ).

3899.

If sec theta + tan theta = 2. find sin theta { theta belongs to(0-90°)}

Answer»

ANSWER:3/5

Step-by-step EXPLANATION:secθ+tanθ=2⟶(1)

Now, sec^2θ−tan^2θ=1

⇒(secθ−tanθ)(secθ+tanθ)=1

⇒2(secθ−tanθ)=1

⇒secθ−tanθ=1/2 ⟶(2)

Adding equations (1)&(2), we get

⇒2secθ=2+1/2 =5/2

⇒secθ=5/4

Or cosθ=4/5

Now, sinθ= $\sqrt{1-cos^2$ ∅

$\sqrt{1-(4/5)^2} \\\sqrt{1-16/25\\} \\\sqrt{9//25}$

Hence,the answer is 3/5
