Select the correct function which corresponds to the following graph: (0,0.5)

exis [7]

Answer: $The\text{ correct function is f\lparen x\rparen= 2}^{x-1}\text{ \lparen option B\rparen}$ Explanation:

Given:

An exponential graph with a given point (0, 0.5)

To find:

the function that corresponds to the graph

To determine the correct function, we will substitute x in each of the functions with the x coordinate of the given point and compare the result with the y coordinate of the given point.

$\begin{gathered} for\text{ point: \lparen0, 0.5\rparen: } \\ x\text{ = 0, y = f\lparen x\rparen = 0.5} \\ \\ a)\text{ f\lparen x\rparen = 2}\times2^{x-1} \\ when\text{ x = 0} \\ f(x)\text{ = 2}\times2^{0-1}\text{ = 2}\times2^{-1} \\ f(x)\text{ = 2}\times\frac{1}{2}\text{ = 1} \\ This\text{ is different from the f\lparen x\rparen value of the given point} \end{gathered}$ $\begin{gathered} b)\text{ f\lparen x\rparen= 2}^{x-1} \\ f(x)\text{ = 2}^{0-1}\text{ = 2}^{-1} \\ f(x)\text{ = }\frac{1}{2}\text{ = 0.5} \\ This\text{ is the same as the f\lparen x\rparen value of the given point} \end{gathered}$ $\begin{gathered} c)\text{ f\lparen x\rparen = 2}\times2^x \\ f(x)\text{ = 2}\times2^0\text{ = 2}\times1 \\ f(x)\text{ = 2} \\ This\text{ is different from the f\lparen x\rparen value of the given point} \end{gathered}$ $\begin{gathered} d)\text{ f\lparen x\rparen= 2}^x \\ f(x)\text{ = 2}^0\text{ = 1} \\ This\text{ is different from the f\lparen x\rparen value of the given point} \end{gathered}$ $\begin{gathered} e)\text{ f\lparen x\rparen= 2}^{x+1} \\ f(x)\text{ = 2}^{0+1}\text{ = 2}^1 \\ f(x)\text{ = 2} \\ This\text{ is different from the f\lparen x\rparen value of the given point} \end{gathered}$

Hence, the correct function that represents the graph is f(x) = 2^(x-1)

A line with a slopeof 8/7 passes through the point (7,8). what is its equation in slope-intercept form?

saw5 [17]

8x - 7y = 0 is the equation in slope-intercept form of the line with a slope of 8/7 passes through the point (7,8). This can be obtained using the formula of equation for the Slope Intercept Form.

<h3>What is its equation in slope-intercept form?</h3>

The formula of equation for the Slope Intercept Form is given below,

y = mx + b,

where m is the slope of the line, b is the y intercept where the line crosses the y-axis at (0, b).

Here in the question it is given that,

The slope of the line is 8/7

The line passes through the point (7,8)

We have to find the equation in slope-intercept form.

By using formula of equation for the Slope Intercept Form we get,

y = mx + b,

here,

⇒ from the point (7, 8), x = 7 and y = 8

⇒ slope, m = 8/7

To find y intercept we use the slope-intercept form equation,

y = mx + b

8 = (8/7)7 + b

8 = 8 + b

⇒ b = 0

Thus the equation in slope-intercept form will be,

y = mx + b

⇒ y = (8/7)x + 0

⇒ 7y = 8x

⇒ 8x - 7y = 0

Hence 8x - 7y = 0 is the equation in slope-intercept form of the line with a slope of 8/7 passes through the point (7,8).

It costs $10 to make earphones, and the start-up costs for manufacturing are $5,000. How many earphones must be produced to get

WINSTONCH [101]

With that information we can create the equation

10x + 5000 = 20x

where x is the number of earphones produced

10x is the cost to make each earphone, 5000 being the fixed costs of manufacturing, and 20x being the total revenue of selling each earphone for $20

Now to solve the equation:

subtract both sides by 10x

10x - 10x + 5000 = 20x - 10x

5000 = 10x

Now divide both sides by 10

5000/10 = 10/10 x

500 = x

Answer: D
