Which function is quadratic?

Function f is defined by f(x) = 1.5^x. Function g is defined by g(x) = 500x^2 + 345x

1. Function f
2. Function g

Answers

Answer 1

Answer:

g(x) is a quadratic function ⇒ 2

Step-by-step explanation:

The quadratic function is the function that has 2 as the greatest power of the variable The form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant

Let us use the information above to solve the question

f(x) = [tex]1.5^{x}[/tex]

∵ x is the exponent of the base 1.5

→ That means f(x) is not in the form of the quadratic function

∴ f(x) is not in the form of the quadratic function above

∴ f(x) does not represent a quadratic function

f(x) is not a quadratic function

g(x) = 500x² + 345x

∴ The greatest power of x is 2

→ That means g(x) is in the form of the quadratic function above

∵ g(x) is in the form of the quadratic function above, where a = 500,

   b = 345, and c = 0 (constant values)

∴ g(x) represents a quadratic function

g(x) is a quadratic function

A racing car travels at a speed of 193 miles per hour.
Work out an estimate for the number of seconds the racing car travels in 10 miles.

Answers

Answer:

The estimate is 186.5 seconds.

Step-by-step explanation:

To calculate the estimate of the time the racing car will take to travel 10 miles, we have to first find the ratio of the original distance to the requested distance.

The number of seconds in an hour is [tex]60 \cdot 60[/tex] seconds, which equals to 3600 seconds.

[tex]\frac{193}{10} = \frac{3600}{x}[/tex]

[tex]19.3 = \frac{3600}{x}[/tex]

[tex]x = \frac{3600}{19.3}[/tex]

[tex]x \approx 186.5[/tex]

Hence, the estimate is 186.5 seconds.

48 people attended the Sunday matinee to watch a film. .Three over 8 of the people went to see a romantic comedy. .One over six of the people went to see an action movie. .The remaining people saw a horror movie. How many people saw a horror movie?

Answers

Answer:

22 people saw an horror movie

Step-by-step explanation:

Total people who attended the Sunday matinee = 48

People who saw romantic comedy = 3/8 of 48

= 3/8 × 48

= (3*48) / 8

= 144 / 8

= 18 people

People who saw action movie = 1/6 of 48

= 1/6 × 48

= 48/6

= 8 people

People who saw horror movie = x

Total people who attended the Sunday matinee = People who saw romantic comedy + People who saw action movie + People who saw horror movie

48 = 18 + 8 + x

48 = 26 + x

Subtract 26 from both sides

48 - 26 = 26 - 26 + x

22 = x

x = 22 people

22 people saw an horror movie

by the definition of supplementary angles, the base angles of the top isosceles triangle have the measure of

Answers

Answer:

128

Step-by-step explanation:

Top Triangle

Let the base angles of the top triangle = y

y + 102 = 180

y = 78

The vertex

Is found by adding the two base angles together and subtract that from 180

y + y + vertex = 180

78 + 78 + vertex = 180

156 + vertex = 180

vertex = 180 - 156

vertex = 24 degrees

Bottom Triangle

Because the base angles are connected by a vertically opposite angle on the bottom triangle, both base angles are 26

Therefore 26 + 26 + x = 180

52 + x = 180

x = 180 - 52

x = 128

An Auditorium has 29 rows, with 115 chairs in each rows. How many chairs does the auditorium have in all? Show your work

Answers

Answer:

3335 chairs

Step-by-step explanation:

To find the total number of chairs, multiply 29 by 115, since there are 29 rows that have 115 chairs:

29(115)

= 3335

So, the auditorium has 3335 chairs in all

Answer: 3335 Chairs

Work: So, the question already gave us how many seats are there per row, now we need to find out how many are there in 29 rows. You multiply 115 by 29 to find out how many seats are there, and you get 3335 chairs. I hope this helps you, and stay safe. :)

equation 1

y = -2x

equation 2

y = x-3

Solution to both

(1,-2)

Step-by-step explanation:

We need to get the equations of both lines

General form is;

y = mx + c

where m is slope and c is the y-intercept

Table 1

since we have a point 0,0; the y-intercept here is zero

Let us get the slope. We can do this by selecting any two points

m = (y2-y1)/(x2-x1)

m = (2-10)/(-1+5) = -8/4 = -2

So the equation of the first line is;

y = -2x

Table 2

we get the slope

m = (4+2)/(7-1) = 6/6 = 1

The partial equation is;

y = x + c

To get c, we select any two point and substitute

4 = 7 + c

c = 4-7

c = -3

So the equation is;

y = x-3

To get the solution to both systems, we equate the y

-2x = x - 3

-2x-x = -3

-3x = -3

x = -3/-3

x = 1

To get y, we substitute;

recall; y = -2x

y = -2(1)

y = -2

Solution to the system is;
