The correct answer is A) 2.30×10^2

This is further explained below.

<h3>What is the estimated distance traveled?</h3>

Generally,

Distance = speed* time  

Distance = 9.50 * speed

distance = 2.30×10^2

In conclusion,It is necessary for an item to move in a straight line at a constant speed for it to be said to have a constant velocity. The object is restricted to moving in an instantaneous course in accordance with the constant route, which is a steady speed way motion in a straight line at a constant velocity.

A good example of steady speed is when a vehicle travels the same distance in the same amount of time while it is traveling at the same constant pace. The ratio of the distance covered by the vehicle from the beginning of its function until it reaches a positive distance in time is used to calculate a car's speed.

A thing's velocity may either be constant or variable, depending on how it's being measured. The speed does not change during the course of uniform motion; rather, it stays the same and gradually increases or decreases whenever the c programming language value is zero. A steady pace is a rate that maintains both its direction and its value in a consistent manner.

Y=(x-3)^2-4

<h2>Steps:</h2>
  • Vertex Form: y = a(x - h)² + k with (h,k) as the vertex

So firstly, let's start with the vertex. Since this is in vertex form, we can find the vertex easily. Since 3 is in the h variable and -4 is in the k variable, <u>the vertex is (3,-4).</u>

Next, the axis of symmetry. Remember that the vertex's x-coordinate and the axis of symmetry are the same. In this case, since the vertex's x-coordinate is 3, this means that <u>the axis of symmetry is x = 3.</u>

Next, whether the vertex is a minimum or a maximum. To determine whether it's a minimum or a maximum, we look towards the a variable of the vertex form. If a is negative, then the parabola opens down and the vertex is a maximum. However, if a is positive, then the parabola opens up and the vertex is a minimum. In this case, a = 1 and since 1 is positive, <u>this makes the vertex a minimum.</u>

Next, to find the y-intercept plug 0 into the x-variable and solve:

y=(0-3)^2-4\\y=(-3)^2-4\\y=9-4\\y=5

<u>The y-intercept is (0,5).</u>

Next, to find the x-intercepts plug 0 into the y-variable to solve. Since it's a bit less straightforward than finding the y-intercept, I will walk through the steps:

0=(x-3)^2-4

Firstly, add 4 to both sides:

4=(x-3)^2

Next, square root both sides:

\pm\ 2=x-3

Next, add 3 to both sides:

3\pm2=x

Lastly, solve the left side twice: once with the plus sign, once with the minus sign:

3+2=x\\5=x\\\\3-2=x\\1=x

<u>Your x-intercepts are (5,0) and (1,0).</u>

<h2>Answers:</h2>

In short:

  • Vertex: (3,-4)
  • x-intercept(s): (5,0) and (1,0)
  • y-intercept(s): (0,5)
  • Axis of symmetry: x = 3
  • Minimum or Maximum? Minimum.

Part 1= You are shopping for a shirt, and you want to get the best deal. You go to two stores, the first of which is JCPenney. W
DedPeter [7]

Answer:

Macy’s

Step-by-step explanation:

let’s find the cost of each shirt

JCPenny’s: 14.99 x 0.80 = $11.99

                   11.99 x 1.06 = $12.70

                   The final cost of the JCPenny shirt is $12.70

Macy’s: 17.99 x 0.65 = $11.69

             11.69 x 1.07 = $12.51

             The final cost of the Macy’s shirt is $12.51

$12.51 is less than $12.70

So, the Macy’s shirt is the better deal :)

Elza [17]

Answer:

West.

Step-by-step explanation:

An old treasure map has the following instructions: stand next to the black rock and face west. Walk 20 yards and then turn 90 degrees clockwise. Walk another 10 yards and then turn 45 degrees anticlockwise. Walk another 15 yards, reverse your directions and walk 5 yards back. Turn 135 degrees clockwise and walk another 10 yards. To determine in which direction you are now facing, the following logical reasoning must be carried out:

You start by walking 20 yards west, then turning 90 degrees clockwise, turning south. Then you walk 10 yards and turn counterclockwise 45 degrees, to the southwest. Later, you walk another 15 yards, turn the direction to the northeast, and walk 5 more yards. From the northeast turn 135 degrees clockwise to the west and walk 10 yards. Thus, the final sense in which the person is walking is to the West.
