Final kinetic energy is equal to gravitational potential energy

KE=PE

(mv^2)/2=mgh

v^2=2gh

Given h=7m and g=9.8m/s^2

v^2=2(9.8)7

v^2=137.2 m^2\s^2

v=11.7 m/s

They rounded to 11.8 m/s for whatever reason :)

Solve the system of equations by using substitution.​

Answers

Answer:

(x,y) = (-1,1)

Step-by-step explanation:

Given the equations

y = 2x + 3

x - y = -2

substitute the value of y in the first equation into the second

x - (2x + 3) = -2

x -2x - 3 = -2

-x - 3 = -2

add 3 to both sides

-x = -2 + 3

- x = 1

Divide both sides by -1

x = -1

Substitute into the first equation

y = 2(-1) + 3

y = -2 + 3

y = 1

Answers

Answer:

∠x = 72°

Step-by-step explanation:

since two sides are equal, their opposite angles are equal.

Then the upper angle is also equal to 54°.

All triangle angles add up to 180°.

∠x = 180 - 54 - 54 = 72°

Answer:

x = 2, y = 4.47, z = 2.24

Step-by-step explanation:

As per diagram we see similar triangles:

ΔADC ≅ ΔCDB

The ratio of corresponding sides:

AD/DC = DC/DB1/x = x/ 4x² = 4x = 2

Use Pythagorean to find the values of y and z:

z = [tex]\sqrt{1^2+2^2}[/tex] = [tex]\sqrt{5}[/tex] = 2.24y = [tex]\sqrt{2^2+4^2}[/tex] = [tex]\sqrt{20}[/tex] = 4.47

Alguém sabe a resposta

Answers

Answer:

6 23/24

Step-by-step explanation:

First, find the least common factor of 8 and 12, the denominators.

8 16 24

12 24

24, is now the current denominnator,

8x 3 = 24

Now you go do it to the numerator, 3 x 3 = 9

9/24 + ?

Now, 12 x 2 = 24, do it to the numerator, 7 x 2 = 14

4 9/24 + 2 14/24

Now add the front numbers to make 6, than add the numerators and keep the denominator.

6 23/24, since you can not simplify this fraction, this is the answer.

Elena and Kiran are playing a board game. After one round, Elena says, "You earned so many more points than I did. If you earned 5 more points, your score would be twice mine!"
Kiran says, "Oh, I don't think I did that much better. I only scored 9 points higher than you did."
If both students were correct, how many points did each student score? Show your reasoning.

Answers

Answer:

Elena's points = 14

Kiran's points = 23

Step-by-step explanation:

Let p = Elena's points

p + 9 = Kiran's points

2p = p + 9 + 5

2p = p + 14

p = 14 = Elena's points

     14 + 9 = 23 = Kiran's points

If Kiran scores 5 more points, he would have 28 points which is twice Elena's 14 points

Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3). Determine the point of intersection of the medians, and state the coordinates

Answers

Answer:

(-5, 3)

Step-by-step explanation:

Let O(x, y) be the centroid of the triangle.

The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.

The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.

For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:

[tex]x=\frac{3 + (-7)+(-11)}{3}=-5\\\\y=\frac{-3 + 9 + 3}{3} =3[/tex]

The centroid is at (-5, 3)

A group of 46 friends are going to a beach house in
Pismo for the weekend. They plan on renting small cars
and large cars to make the trip.
Each small car can hold 2 people and each large car
can hold 4 people. They rented 8 more small cars than
large cars.
Determine the number of small cars they rented and
the number of large cars they rented.
1) Define your variables with "Let" statements.

Answers

5 large cars, 13 small cars

Let s = # of small cars (2 people)
Let l = # of large cars (4 people)

2s + 4l = 46
l + 8 = s

2(l + 8) + 4l = 46
2l + 16 + 4l = 46
6l = 30
l = 5

Check:
2s + 4l = 46
2(13) + 4(5) = 46
26 + 20 = 46
46 = 46
small car (x) seat 2 people
large car (y) seat 4 people
Total number of people is 46
8 more small cats than large cats(8+y=x)
2x+4y=46
x=8+y
2(8+y)+4y=46
16+2y+4y=46
6y=46-16
6y=30
y=30/6
y=5 aka 5 large cars

x=8+y
x=8+5
x=13 aka 13 small cars

2•13+4•5=26+20=46 seats for everyone
