If you vertically stretch the square root parent function, F(x)= square roor x, by 7 units, what is the equation of the new function?

Answers

Answer:

g(x) = 7√x

Step-by-step explanation:

Parent function:  f(x) = √x

Parent function vertically stretched by a factor of 7:  g(x) = 7√x

The equation of the new function is 7√x.

What is a scale factor?

Scale factor is that it is a number that multiplies times a given quantity to produce a smaller or larger version of the original number. The ratio of any two corresponding lengths in two similar geometric figures.

For the given situation,

The equation is F(x) = √x

The parent function is vertically stretched by 7 units.

So, the new function is

⇒ [tex]7(\sqrt{x} )[/tex]

⇒ [tex]7\sqrt{x}[/tex]

Hence we can conclude that the equation of the new function is 7√x.

Write an inequality that describes the graph

Answers

Answer:

x<4

Step-by-step explanation:

The arrow is facing left, making it less than. Next, the open circle on 4 means that it does not include 4, therefore the inequality is x<4.  

The inequality that represents this situation is - ∞ ≤  x < 4.

What are inequalities and their types?

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a b.

a is bigger or equal value of an is indicated by the notation a b.

Assuming the number line is represented by x.

An open circle on the right-hand side of the line at 4 represents it is less than 4.

We can also observe that the line is going infinitely in the direction of negative infinity.

So, this situation can be represented by an inequality of the form

- ∞ ≤  x < 4.

If the spinner is spun 40 times, then it should land on Red:

Jacob sold 40 candy bars and made $65. He sold two types of
bars - chocolate for $2 each and peanut butter for $1 each.
How many of each type of candy bar did Jacob sell?

Answers

Answer:

Jacob sold 25 bars - chocolates and 15 peanut butter.

Step-by-step explanation:

Jacob sold 40 candy bars.

Let the bars - chocolate be x and peanut butter be y and made $65.

Now,

x + y = 40 ...(1)

2x + y = 65 ...(2)

Now, From equation (1) we get,

x + y = 40

x = 40 - y

Now, put the value of x = 40 - y in equation (2) we get,

2x + y = 65

2(40 - y) + y = 65

80 - 2y + y = 65

y = 80 - 65

y = 15

Now, put the value of y in equation (1)

x + y = 40

x + 15 = 40

x = 40 - 15

x = 25

The bars - chocolate = x = 25 and

peanut butter = y = 15

Thus, Jacob sold 25 bars - chocolates and 15 peanut butter.

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)

Answers

Answer:

the answer is A. y=2sin(1/2x)+1

Step-by-step explanation:

I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph

The function that matches the graph is y= 2 sin(1/2x) +1.

What is graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

let y = A sin ([tex]\omega[/tex]x + Ф)+  k

T= 4π, w= 2π/T = 1/2

Now, midline= 1/2( max + min)

=1/2(3-1)= 2/2

k=1

and, A= 3-1 = 2

So, y= 2 sin(1/2x  + Ф) +1

as, Ф=0

So, y= 2 sin(1/2x) +1

What is the surface area of a cube with a side length of 3/4 inch? Use the expression 6s 2, where is the side length of the cube

Answers

Answer: The surface area of the cube would be 3^3/4.

Step-by-step explanation:

A cube has 6 faces [ 6 surfaces ]. Each surface has a square shape.

The area of 1 surface=  (side)^2=  3/4 · 3/4= 9/16 sqr.in.

Surface area of cube =9/16 · 1/6= 54/16.

divide both top and bottom (54 and 16) by 2. you should end up with 27/8.
