MissTica3 years ago

Answer:

a = 18

Step-by-step explanation:

Step 1: Cross-multiply.

  • 0.5 * a = 10*0.9
  • 0.5a =9  

Step 2: Divide both sides by 0.5

  • \frac{0.5a}{0.5} =\frac{9}{0.5}
  • a = \frac{90}{5}
  • a = 18

Step 3: Check if solution is correct.

  • \frac{0.9}{0.5}=\frac{18}{10}
  • \frac{9}{5} =\frac{18}{10}  
  • \frac{18/2}{10/2} =\frac{9}{5}
  • \frac{9}{5} =\frac{9}{5}

Therefore, a = 18.

Identify a transformation of the function f(x) = x by observing the equation of the function g(x) = x − 90.
ycow [4]

The transformation of a function may involve any change. The transformation of the function is Right shift by 90 units.

<h3>How does the transformation of a function happen?</h3>

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:

y=f(x+c) (same output, but c units earlier)

Right shift by c units:

y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k \times f(x)

Horizontal stretch by a factor k: y = f\left(\dfrac{x}{k}\right)

Since the function is transformed from f(x)=x to g(x)=x-90, therefore, the transformation of the function is Right shift by 90 units.

If pr = 4x – 2 and rs = 3x – 5, which expression represents ps?
slamgirl [31]
This is from simple math knowledge of lines, segments and points. From the given data, pr and rs are line segments in the line ps. Thus, we add segments pr and rs together to solve for the line ps. 

pr + rs = ps
4x - 2 + 3x - 5 
(Add like terms) = 7x -7
(Further simplify) = 7(x-1)

Therefore, the final answer or expression of ps = 7(x-1).

Identify the initial amount a and the growth or decay factor b in the exponential function. y = 0.01025^x
Nastasia [14]

Answer:

The initial amount a = 1

The growth or decay factor  = 0.01025

Step-by-step explanation:

The exponential function.

y = 0.01025^x

The initial amount a = 1

The growth or decay factor  = 0.01025

The exponential equation can be rewritten as Y = 1(0.01025)^x
