Un objeto cae accidentalmente de un vehículo con una velocidad de
50 km / hy recorra 20 m antes de detenerse.
Calcular:
a) La aceleración:
b) El tiempo que tarda en detenerse:
Responder:
1.439 s
-9,645 m / s²
Explicación paso a paso:
Dado que:
Velocidad en m / s = (50 * 1000) / 3600 = 13.899 m / s
Distancia (d) = 20
Tiempo = distancia / velocidad
Tiempo = 20 / 13.889
Tiempo = 1.439 s
Aceleración (a):
Cambio de velocidad / tiempo empleado
= (0 - 13,889) / 1,439
- 13.889 / 1.439
= -9,645 m / s²
Which of the following inequalities has a solution x≥−3
3(x−1)≤4x
x≥x+32
x6≤x2−1
x+4≥x3
Answer: A
Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3
The inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.
What is inequality?inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The inequality 3(x-1) ≤ 4x will be solved as below:-
3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3. The complete solution is given below:-
3(x-1) ≤ 4x
3x - 3 ≤ 4x
-3 ≤ 4x - 3x
-3 ≤ x
x ≥ -3
Therefore, the inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.

Which graph represents the polynomial function h(x) = x3 + 2x2 – 11x – 12?
y
Answer:
I attached a pic of the answer. I just did the quiz. Hope this helps!!!
Step-by-step explanation:
The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.
Given that,
To determine the graph of the polynomial function h(x) = x³ + 2x² - 11x -12.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups and down,
So the graph can be drawn as shown in the image.
Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

A restaurant bill or lunch is $18 and the sales tax will be 6.5%. Savannah wants to leave a 15% tip. How much will lunch cost including the tax and the tip?
Answer:
$21.87
Step-by-step explanation:
Given that :
Cost of lunch = $18
Sales tax = 6.5%
Intended tip to leave = 15%
Cost of lunch including tip and tax =?
Sales tax = 0.065 * 18 = $1.17
Tip = 0.15 * $18 = $2.70
Cist of lunch including tip and tax :
($18 + $1.17 + $2.70)
= $21.87

Describe how to find the slope of a line through two points
Answer:
There are three steps in calculating the slope of a straight line when you are not given its equation.
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
Step-by-step explanation:
Answer:
Step one: identify two point on the line
Step two:. select one to be ( x1, y1) and the other to be (x2, y2).

Answer:
y= -2x + 80
Step-by-step explanation:
First, you need to find the slope, which can be done by subtracting the change in y over the change in x. The easiest points to pick are (30,20) and (40,0). Do 20-0 which is -20, then divide that by 40-30, and you get -2. Then to find the y intercept, pick a point (like 40,0). Then do 0 = -2(40) + b, and solving for b you get 80.

M=y2-y1/x2-x1
Answer:
4/3
Step-by-step explanation:
Use the formula
x2-x1 over y2-y1
since it goes by (x,y) label the given points
(6,7) and (10,10)
6 is your first x (x1)
7 is you first y (y1)
onto the next point...(10,10)
10 would be your second x (x2)
and your second y would also be 10 (y2)
Now plug into formula x2-x1 over y2-y1
10-6 over 10-7= 4/3

A dog kennel boards dogs for $8 a day. The kennel will also groom a dog for $12. The DeVilles have $52 budgeted for caring for the dog while they are on vacation. How many days, d, can they put the dog in the kennel if they are going to have the dog groomed? Write an equation to model this situation and solve
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that a dog kennel boards dogs for $8 a day, the kennel will also groom a dog for $12 and that DeVilles have $52 budgeted for caring for the dog while they are on vacation.
Let the number of days that they can put the dog in the kennel if they are going to have the dog groomed be represented by d.
Therefore,
8d + 12d ≥ 52
20d ≥ 52
d ≥ 52/20
d ≥ 2.6
Since DeVilles have $52 budgeted for caring for the dog, the number of days they can put the dog in the kernel will be 2 days.

Johan has 15 bags of potato chips. All his 6 friends want 3/5 of a bad of chips, so he pours the chips into bowls. He takes a whole bag. How many full bags are left?
Please help!
Answer:
3/5 is equal to 0.6 multiply 0.6 by 6... subtract 3.6 from 15 and subtract one more bag because Johan took one whole bag of chips... there would be 10.4 bags of chips (about 10.5 bags of chips left).

This if for my study guide and I'm so confused, can someone help me with this one?
Answer:
The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a.
The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.
The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.
A line is a relationship between two things - but not just any relationship. When you have a linear relationship, one that can be graphed as a line, there is one big condition:
No matter how much you have of a thing (often called x), if you add one more you always get a consistent amount more of the other thing (often called y).
