a 10-kg object traveling at 6 m/s collides head on with a 2-kg object at rest. What is the total momentum of the system after the collision?
Answer:
M1V1i+M2V2i=(M1 + M2)vf
(10)(6)+(2)(0)=(10+2)vf
60=12vf
60÷12 =12vf÷12
5=vf
::Vf=5ms-1 to the right

When a shape is dilated, the size of the shape changes
The true statement is (d) The scale factor is 2.5.
What is dilation?Dilation involves changing the size of a shape or figure
How to determine the scale factorIn figure A, we have:
Length = 0.6
In figure B, we have:
Length =1.5
The scale factor is then calculated as:
[tex]k = \frac{1.5}{0.6}[/tex]
Divide
[tex]k = 2.5[/tex]
Hence, the true statement is (d) The scale factor is 2.5.

Question 4 The 6th grade class is raising money for a camping trip to the mountains. So far they have raised $900, which is 60% of the total cost. How much money does the total trip cost?
Answer:
1500
Step-by-step explanation:
Total cost would be 60%+40%
Since we have 60% amount already
0.60* total cost=900
total cost=90000/60
=1500

show that (4p^2-3q)^2+48p^2q =(4p^2+3q^2)
Given:
The statement is
[tex](4p^2-3q)^2+48p^2q=(4p^2+3q^2)[/tex]
To prove:
The given statement.
Solution:
We have,
[tex](4p^2-3q)^2+48p^2q=(4p^2+3q^2)[/tex]
Now,
[tex]LHS=(4p^2-3q)^2+48p^2q[/tex]
Using [tex](a-b)^2=a^2+b^2-2ab[/tex], we get
[tex]LHS=(4p^2)^2+(3q)^2-2(4p^2)(3q)+48p^2q[/tex]
[tex]LHS=(4p^2)^2+(3q)^2-24p^2q+48p^2q[/tex]
[tex]LHS=(4p^2)^2+(3q)^2+24p^2q[/tex]
It can be rewritten as
[tex]LHS=(4p^2)^2+(3q)^2+2(4p^2)(3q)[/tex]
Using [tex](a+b)^2=a^2+b^2+2ab[/tex], we get
[tex]LHS=(4p^2+3q^2)[/tex]
[tex]LHS=RHS[/tex]
Hence proved.

Combine the like terms to create an equivalent expression:
-k+3k
Answer:
=ykvnn
Step-by-step explanation:
Answer: 2k
Step-by-step explanation:
Like terms are terms that have the same variables and powers.
k is the same variable so you would take away k (or 1k we just don’t write 1k in algebra) from 3k=2k
x2 + 13x + 36
x2 – 7x + 10
Answer:1.1 Factoring x2 - 13x - 36
Step-by-step explanation:
Find the mistake!
1/4(x+12)=2
1/4x=10
x=-40
26x + 13y = 39
.
Rearrange this equation so it is in the form y = mx + b
After you have rearranged the equation, identify the slope and the y-intercept.
If x = 6, what should y =? Show all necessary work and steps. Round any decimals to
1 place as necessary.
If y = -1, what should x =? Show all necessary work and steps. Round any decimals
to 1 place as necessary.
Answer:
Rearrange: y=-2x+3
if x=6 then y = -9
if y=-1 then x = 2
Step-by-step explanation:
Algebra
to rearrange here are the steps
26x+13y=39
First move x to other side by subtraction
13y= -26x+39
to get y as just y divide everything by 13. Since 13/13=1 or 13y/13= y
y=-2x+3

A four-sided polygon has sides that measure 1 cm, 5cm, and 7 cm. (Forth side not given). What is the perimeter?
Answer:
(13+x)cm
Step-by-step explanation:
Given data
Length of sides
1cm, 5cm, 7cm
Since the shape is four-sided and the fourth side is not given, let the fourth side be x
so
The perimeter of the polygon is
P= 1+5+7+x
P= 13+x
Hence the perimeter of the polygon is
P= (13+x)cm
Given the point and its image, determine the scale factor. B(2,5) B'(1,2.5) 0 -1/2 02 0-2 O 1/2
Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as
[tex]k=\dfrac{\text{x-coordinate of the point on image}}{\text{x-coordinate of the corresponding point on the original figure}}[/tex]
x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is
[tex]k=\dfrac{1}{2}[/tex]
Therefore, the scale factor is [tex]\dfrac{1}{2}[/tex] and the correct option is D.
