The graph of g(x) shown below resembles the graph of f(x) = x2, but it has
been reflected over the x-axis. Which is the equation of g(x)?

Answers

Answer:

A. g(x) = - x²

Step-by-step explanation:

f(x) reflex over x-axis: g(x) = - f(x)

Using translation concepts, it is found that the equation of g(x) is given by:

A. g(x) = -x².

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function f(x) = x² was reflected over the x-axis, that is, it was multiplied by -1, hence the equation for g(x) is given by:

g(x) = -f(x) = -x².

Which means that option A is correct.

Nick spent 34 minutes on the phone while routing 17 phone calls. In all, how many phone calls does Nick have to route to spend a total of 50 minutes on the phone? Assume the relationship is directly proportional.

Answers

Answer:

25 phone calls

Step-by-step explanation:

Create a proportion where x is the number of phone calls for 50 minutes on the phone:

[tex]\frac{34}{17}[/tex] = [tex]\frac{50}{x}[/tex]

Cross multiply and solve for x:

34x = 850

x = 25

So, Nick would have to make 25 phone calls

Show two different ways to find the solution.Part B: The paintings have areas of 1,600in^2 and 484in^2, respectively. A potential buyer went to an exhibition and argued that the value of xfor both paintings is the same. Is he right? Prove it.

Answers

Answer:

56x² - 120x + 16 ; (9x - 5)² - (5x - 3)²

x in both equations is 5

Step-by-step explanation:

Painting 1 : 81x^2 - 90x + 25

Painting 2 : 25x^2 + 30x + 9

Expression for the difference between the two paintings :

Painting 1 - painting 2

(81x^2 - 90x + 25) - (25x^2 + 30x + 9)

81x^2 - 90x + 25 - 25x^2 - 30x - 9

81x² - 25x² - 90x - 30x + 25 - 9

56x² - 120x + 16

2.)

81x^2 - 90x + 25 = 1600in²

25x^2 + 30x + 9 = 484 in²

Factorizing each equation :

81x^2 - 90x + 25 = 1600 in²

(9x - 5)^2 = 1600 in²

25x^2 + 30x + 9 = 484 in²

(5x - 3)^2 = 484

(9x - 5)² - (5x - 3)²

2.)

(9x - 5)^2 = 1600

Take square root of both sides

9x - 5 = 40

9x = 40 + 5

9x = 45

x = 45/9

x = 5

(5x - 3)^2 = 484

Take square root of both sides

5x - 3 = 22

5x = 22 + 3

5x = 25

x = 25/5

x = 5

Elizabeth purchased a $20 bus pass. Each time she rides the bus $1.25 is deducted from the pass. What equation would represent this scenario? *

y= 1.25x - 20
y= -1.25x + 20
y= 20x - 1.25
y= 20x + 1.25

Answers

Answer:

Y = 1.25x - 20

Step-by-step explanation:

Everytime she rides the bus 1.25 is taken away from that 20.

The x = Every ride

For example

say she rode the bus 5 times so it would be

1.25 × 5 = 6.25 now you take the answer and subtract it from the 20

20 - 6.25 = 13.75

An object is dropped from a height of 150 feet. Its heights s at time, t is given by the

equation s(t) =-16t^2+150 ,where s is measured in feet and t is measured in seconds.

Find the average rate of change of the height over the interval [1, 2.5).

O 1) -56 ft/sec

O2) 77 ft/sec

03) 56 ft/sec

O4) -35 ft/sec

Answers

Answer:

The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

Step-by-step explanation:

Let [tex]s(t) = -16\cdot t^{2} + 150[/tex]. Geometrically speaking, average rate of change over a given interval ([tex]\bar v[/tex]), measured in feet per second, is determined by definition of secant line, which is defined:

[tex]\bar v = \frac{s(t_{2})-s(t_{1}) }{t_{2}-t_{1}}[/tex] (1)

Where:

[tex]s(t_{1})[/tex], [tex]s(t_{2})[/tex] - Initial and final position of the object, measured in feet.

[tex]t_{1}[/tex], [tex]t_{2}[/tex] - Initial and final times, measured in seconds.

If we know that [tex]t_{1} = 1\,s[/tex] and [tex]t_{2} = 2.5\,s[/tex], then the average rate of change over the interval [tex][1,2.5][/tex]:

[tex]s(1) = -16\cdot (1)^{2}+150[/tex]

[tex]s(1) = 134[/tex]

[tex]s(2.5) = -16\cdot (2.5)^{2}+150[/tex]

[tex]s(2.5) = 50[/tex]

[tex]\bar v = \frac{50\,ft-134\,ft}{2.5\,s-1\,s}[/tex]

[tex]\bar v = -56\,\frac{ft}{s}[/tex]

The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

3. The area A of a triangle varies jointly as the base b and the altitude h of the triangle. If the area
of a triangle is 70 cm2 when the base is 14 cm and the altitude is 10 cm, find the area if the base is
8 cm and the altitude is 12 cm.​

Answers

Answer:

48cm²

Step-by-step explanation:

If the area A of a triangle varies jointly as the base b and the altitude h of the triangle, this is expressed as;

A = kbh

k is the constant of proportionality

If A  = 70cm², b = 14cm and h = 10cm

Substitute

70 = k(14)(10)

70 = 140k

k = 70/140

k = 0.5

To get the area if base is  8 cm and the altitude is 12 cm;

A = 0.5*8*12

A = ​48cm²

Hence the required area is 48cm²
