(502)2 - (498)2
Solution:
(502)2 -(498)2
Since the given algebraic expression is in the form of a2 – b2 so, here we will directly apply the formula a2 - b2 = (a + b) (a – b) to evaluate the difference of two squares.
HOPE IT HELPS YOU!!!The difference of the squares of, 104² - 96², can be written as: (104 - 96)(104 + 96).
It is evaluated as: 104² - 96² = 1,600
Recall:
The difference of two squares, i.e. x² - y², can be expressed and evaluated as;
x² - y² = (x - y)(x + y)Given:
104² - 96²
The difference can be expressed and evaluated as shown below:
104² - 96² = (104 - 96)(104 + 96)
104² - 96² = (8)(200)
104² - 96² = 1,600Therefore, the difference of the squares of, 104² - 96², can be written as: (104 - 96)(104 + 96).
It is evaluated as: 104² - 96² = 1,600

Triangle Deff is shown below. 110°, e, d, f, 135°
Answers
Answer:
Step-by-step explanation:
a° + 110° = 180° [Linear pair of angles]
a = 180° - 110°
a = 70°
b° + 135° = 180° [Linear pair of angles]
b = 180° - 135°
b = 45°
a + b + c = 180° [Triangle sum theorem]
45° + 70° + c = 180°
c = 180° - 115°
c = 65°
Therefore, a triangle similar to DEF will have an angle that measures 45 degrees, an angle that measures 70 degrees and an angle that measures 65 degrees.

Determine the center and radius of the following circle equation: x^2+y^2-8x+6y-75=0 x 2 +y 2 −8x+6y−75=0 Center: \big(( , \big)) Radius:
Answers
Answer:
Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0
-2a =-8 And -2b=-6
a=4 b=3
c=-75
To find the radius use the equation
r^2=a^2+b^2-c
r^2=4^2+ 3^2-(-75)
r^2=25+75=100
r=10(radius is always positive)
Hence the center is (4,3) and radius 10

A company is desinging a square prism. Its height is 3 yarss longer than a side of its base. The volume of the prism must be 20 cubic yards. Write a representative function for the volune of the solid..
Answers
Answer:
[tex]a^{2} (a+3) = 20\\OR\\a^3 +3a^2 -20 = 0[/tex]
Step-by-step explanation:
Given that:
There is a square prism which has height equal to 3 yards longer than that of the base of the prism.
Let the base of prism = [tex]a[/tex] units
As per question statement:
Height, [tex]h = (a+3)[/tex] units
Volume of the prism = 20 cubic yards
Now, we have to find a representative function that will represent the volume of the solid.
First of all, let us have a look at the formula for volume of a prism.
[tex]V = B\times h[/tex]
Where, [tex]B[/tex] is the area of base and
[tex]h[/tex] is the height of prism.
And the base is a square, whose area will be represented as:
[tex]B = Side \times Side[/tex]
Now, putting the values in the formula for Volume:
[tex]V = a^2(a+3) = 20\\OR\\a^3+3a - 20 =0[/tex]

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s and the water strikes the door horizontally and doesnt bounce back. What average force is exerted by the stream of water?
Answers
Answer:
[tex]6400\ \text{N}[/tex]
Step-by-step explanation:
[tex]\dfrac{m}{t}[/tex] = Mass flow rate of water = 320 kg/s
[tex]m[/tex] = Mass of water on the door
[tex]t[/tex] = Time
[tex]v[/tex] = Velocity of water on the door = 20 m/s
Force is given by
[tex]F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}[/tex]
The average force is exerted by the stream of water is [tex]6400\ \text{N}[/tex].
Ashley has $9.05 in dimes and nickels. If she has a total of 108 coins, how many of each type does she have?
Answers
Answer:
[tex]73\:\mathrm{dimes},\\35\:\mathrm{nickels}[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}10d+5n=905,\\d+n=108,\\\end{cases}[/tex], where [tex]d[/tex] is the number of dimes she has and [tex]n[/tex] is the number of nickels she has.
Multiply the second equation by [tex]-5[/tex] and add both equations to solve for [tex]d[/tex]:
[tex]\begin{cases}10d+5n=905,\\-5d-5n=-540,\\\end{cases}\\5d=365,\\d=\fbox{$73$}[/tex].
Plug [tex]d=73[/tex] into any equation to solve for [tex]n[/tex]:
[tex]73+n=108, \\n=\fbox{$35$}[/tex]
There are 73 dimes and 35 nickels.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Ashley has $9.05 in dimes and nickels. If she has a total of 108 coins,
dime = 10
A nickel = 5
We can write the following system of equations;
10D + 5N = 905
N + D = 108 coins
where D is the number of dimes she has and N is the number of nickels she has.
Multiply the second equation by -5 and add both equations to solve for :
10D + 5N = 905
-5N -5 D = -540 coins
Use the Distributive Property:
Add the like terms:
5D = 365
Divide both sides by 5
D = 73
Plug D into any equation to solve for N
Nickels = 108 - 73 = 35
There are 73 dimes and 35 nickels.

Answer:
x = 1z = 11Step-by-step explanation:
If we assume that the segment marked (2x+1) is a midsegment, then it is half the length of the parallel base:
2(2x+1) = 8x-2
4x +2 = 8x -2 . . . . eliminate parentheses
4 = 4x . . . . . . . . . . add 2-4x to both sides
1 = x . . . . . . . divide by 4

The above assumption makes the two segments marked with z-expressions be the same length:
3z = z +22
2z = 22 . . . . . . subtract z
z = 11 . . . . . . . . . divide by 2
The values of X and Z are 1 and 11, respectively.
