3) Scenario 1 Scenario 2 y = 50x x is time in hours y is distance in miles Compare the scenarios and determine which shows the g

Olegator [25]

Answer:

Option A.

Step-by-step explanation:

Consider the below figure attached with this question.

Scenario 1 represented by the graph.

From the graph it is clear that the line passes through the points (1,60) and (2,120).

Slope of the line is

$y=\dfrac{y_2-y_1}{x_2-x_1}$

$y=\dfrac{120-60}{2-1}=60$

The slope of line is 60. It means the speed is 60 miles per hour.

Scenario 2 defined by the equation,

$y=50x$

If an equation defined as $y=mx+b$ , then m is slope and b is y-intercept.

$m=50$

The slope of line is 50. It means the speed is 50 miles per hour.

The slope of Scenario 1 is greater than slope of Scenario 2. So, the Scenario 1 shows the greater speed.

Hence, the correct option is A.

Answer: 16) $\bold{\sqrt{x}}$ (17) $\bold{\dfrac{x-4}{2}}$ (18) $\bold{\sqrt{x}-2}$ (19) 3x - 18

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

$\bold{\sqrt{x} =y}$

17) Given: y = 2x + 4

Swapped: x = 2y + 4

x - 4 = 2y

$\bold{\dfrac{x-4}{2}=y}$

18) Given: y = (x + 2)²

Swapped: x = (y + 2)²

√x = y + 2

$\bold{\sqrt{x}-2=y}$

19) Given: $y=\dfrac{1}{3}x+6$

Swapped: $x=\dfrac{1}{3}y+6$

$x - 6 = \dfrac{1}{3}y$

3(x - 6) = y

3x - 18 = y

An object is thrown upward from the top of 80 ft tower.The height h of the object after t seconds is represented by the quadrati

Sedaia [141]

Answer:The object will hit the ground after 5 seconds

Step-by-step explanation:

Given height of tower =80 ft

h=-16 $t^{2}$ +64t+80

When the object will hit the ground its height=0

0=-16 $t^{2}$ +64t+80

Multiplying both sides by -1

16t²-64t-80=0

Dividing by 16 both sides

t²-4t-5=0

(t-5)(t+1)=0

t=5 or -1

So t=5 since time cannot be negative

The object will fall after 5 seconds
