What is the effect on the graph of the function f(x) = x when f(x) is replaced with -1/2 f(x)?
inn [45]

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

f(x)=x

The new function is

g(x)=-\frac{1}{2}f(x)

g(x)=-\frac{1}{2}x        .... (1)

It is in the form of

g(x)=mx                   .... (2)

Where, m is a constant.

If m is negative, then there is a vertical reflection over x-axis. If the constant is greater than 1, we get a vertical stretch and  if the constant is between 0 and 1, we get a vertical compression.

From (1) and (2), we get

m=-\frac{1}{2}

Since the value of m is negative and absolute value of m is between 0 and 1, therefore the graph g(x) shows the vertical reflection over x-axis and vertical compression.

Option B is correct.

Answer:

the ratio is equal to

x:y:z=1,000:269:61

Step-by-step explanation:

Let

x ---> the amount of water in ml

y ---> the amount of sucrose in ml

z ---> the amount of saline in ml

Remember that

1\ L=1,000\ ml

Convert 1 L of water in ml

1\ L=(1)(1,000)=1,000\ ml

the ratio is equal to

x:y:z=1,000:269:61 -----> irreducible

I need your help (circle theorem question).
bixtya [17]

Answer:

b = 108

c = 72

Step-by-step explanation:

The triangle formed by the two tangents is an isosceles triangle.

180 - 72 = 108

108/2 = 54

The other two angles in the triangle are equal to 54 degrees.

A tangent always meets the radius line at a right angle. Therefore, the radius line (between b and c) meets the tangent at 90 degrees.

90 - 54 = 36

Therefore the other two angles of 'b' triangle are equal to 36 degrees.

36 x 2 = 72

180 - 72 = 108

b = 108

And therefore b is equal to 108 degrees.

b + c = 180 (because a straight line is always equal to 180 degrees)

180 - 108 = 72

So c = 72
