Here we use the equation

y = a(b)^x

Taking points (0,4), (1,2)

Substituting the point (0,4) , we will get

4 = a(b)^0
\\
4 = a(1)  \\
a =4

Substituting (1,2) we will get

2 = 4 (b)^1
\\
2/4 = b
\\
b = 1/2

So we have

a = 4, b = 1/2

Therefore , required equation is

y = 4(1/2)^x

Given:

The base of the given triangle has two part:

Left( left side of the hypotenuse) = 25

Right ( right side of the hypotenuse) = x

The altitude (h) = 60

To find the value of x.

Formula:

By Altitude rule we know that, the altitude of a triangle is mean proportional between the right and left part of the hypotenuse,

\frac{left}{altitude} =\frac{altitude}{right}

Now,

Putting,

left = 25, altitude = 60 and right = x we get,

\frac{25}{60} =\frac{60}{x}

or, (25)(x )=(60)(60) [ by cross multiplication]

or, x = \frac{3600}{25}

or, x = 144

Hence,

The value of x is 144.

The graph of function g is a vertical stretch of the graph of function f ​​by a factor of 3. Which equation describes function g
anyanavicka [17]

Answer:


Step-by-step explanation:

A vertical stretch by a factor of k means that the point (x, y) on the graph of f (x) is transformed to the point (x, ky) on the graph of g(x), where k <1.

If k =1, then same graph we obtain and if k>1 we get a vertically shrink graph.

In our question, there is a vertical stretch of 3. This means new graph would have points as (x,y/3)

i.e. instead of f(x) = y, we have now f(x) = y/3

So transformation is g(x) = 3f(x)

Option A is correct.

2) Here f(x) = 3x+8 is transformed to g(x) =3x+6

i.e. y intercept is reduced by 2 units.  Hence there is a translation of 2 units down.
