Answer 1

Answer:

Answer:

1) h = -1/2t^2 +10t

2) h = -1/2(t -10)^2 +72

3) domain: [0, 20]; range: [0, 50]

Step-by-step explanation:

1.) I find it easiest to start with the vertex form when the vertex is given. The equation of the presumed parabolic path for Firework 1 is ...

h = a(t -10)^2 +50

To find the value of "a", we must use another point on the graph. (0, 0) works nicely:

0 = a(0 -10)^2 +50

-100a = 50 . . . . . . subtract 100a

a = -1/2 . . . . . . . . . divide by -100

Then the standard-form equation is ...

h = (-1/2)(t^2 -20t +100) +50

h = -1/2t^2 +10t

2.) The path of Firework 2 is translated upward by 22 units from that of Firework 1.

h = -1/2(t -10)^2 +72

3.) The horizontal extent of the graph for Firework 1 is ...

domain: 0 ≤ t ≤ 20

The vertical extent of the graph for Firework 1 is ...

range: 0 ≤ h ≤ 50

David says he has 2/3 of a pipe length left, while Don says he has 11/16 of a length left. Which person has the longest section left?

Answers

Don has the longest section of pipe because the fraction number 11/16 is greater than the fraction number 2/3.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The decimal number is the sum of a whole number and part of a fraction number. The fraction number is greater than zero but less than one.

David says he has 2/3 of a line length left, while Wear says he has 11/16 of a length left.

Convert the fraction numbers 2/3 and 11/16 into the decimal number. Then we have

2/3 = 0.6667

11/16 = 0.6875

The decimal number 0.6875 is greater than 0.6667. Then the fraction number 11/16 is greater than the fraction number 2/3.

Don has the longest section of pipe because the fraction number 11/16 is greater than the fraction number 2/3.

#SPJ2

Answer:

Don

Step-by-step explanation:

1. We make the fractions have common denominators so it is easier to compare them. We can do this buy multiplying 2/3 by a factor of 16, so it becomes 32/48. For 11/16, we multiply by a factor of 3 so it becomes 33/48. It is now apparent that Don has the longer pipe.

Answer:

the correct answer is marked

Step-by-step explanation:

When the graph of the left side of the equation does not intersect the graph of the right side of the equation, there are no solutions.

Additional comment

Even if you extend the domain to complex numbers, there are no solutions. The f(x) = |x| function always returns a positive real value, even for complex numbers.

Answer:

y=20x+25, this equation is linear, the rate of change is constant

Step-by-step explanation:

She starts with 25$, that doesn't change so its our constant. Let x represent each week. Each week she ears 20$

So, let y represent the total amount of money she has

y=20x+25, this equation is linear, the rate of change is constant

the answer is y=20x+25
