Prove cosxtanx = sinx

Answers

Answer 1
cos(x)tan(x)

Transform the expression by using the formula for tan theta:
tan(t)= sin(t)/cos(t)

cos(x)= sin(x)/cos(x)

Cancel out the cos(x) since it’s on both sides

Final answer : sin(x)

cos(x)tan(x) is equal to sin(x)

Which equation represents a line which is perpendicular to the y-axis?

Answers

Answer:

The real answer is y=5

Step-by-step explanation:

because its horizontal

y=5  represents a line which is perpendicular to the y-axis

What is Straight line?

A line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects

We need to find the equation which  represents a line that is perpendicular to the y-axis

A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.

In the given options

x=-6

y=x-4

y=5

and x=-2y

The only horizontal line is y=5

Hence, y=5  represents a line which is perpendicular to the y-axis

The endpoints of directed line segment PQ have coordinates of P (-7, -5) and Q (5, 3). What are the coordinates of point A, on segment PQ, that divide segment PQ into a ratio of 1:3?

Answers

Answer:

(2,1)

Step-by-step explanation:

The coordinate point between two points divided between ratio a and b is expressed as;

(X, Y) = [(ax1+bx2/a+b,ay1+by2/a+b]

Given the coordinate points (-7,-5) and (5,3) divided within the ratio 1:3

X = ax1+bx2/a+b

X = 1(-7)+3(5)/1+3

X = -7+15/4

X = 8/4

X = 3

Similarly

Y = ay1+by2/a+b

Y = 1(-5)+3(3)/1+3

Y = -5+9/4

Y = 4/4

Y = 1

Hence the required coordinate point is (2,1)

Answers

Answer:

this problem has this form, (x,y) (x-7)(y+5) and tells you that the X and Y coordinates are translated to X-7 and Y+5.

Step-by-step explanation:

The translated point A' of the triangle is given by A' ( -3 , 13 )

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.

Given data ,

Let the triangle be represented as ΔABC

Now , the coordinates of the triangle are

A ( 7 , 5 ) , B ( 2 , 9 ) and C ( 1 , 3 )

Now , the triangle is translated 4 units left and 8 units up

To translate the point A(7,5) 4 units to the left and 8 units up, we subtract 4 from the x-coordinate and add 8 to the y-coordinate:

A'(3,13)

To reflect this point across the y-axis, we change the sign of the x-coordinate:

A'(-3,13)

Hence , the translated point is A' ( -3 , 13 )
