Step-by-step explanation:
a^2-b^2
(a-b)(a+b)
Answer:
[tex](a-b)(a+b)[/tex]
Step-by-step explanation:
This particular pattern: [tex]a^2-b^2[/tex]; is the difference of squares pattern.
Difference of Squares Pattern: [tex](a-b)(a+b)=a^2-b^2[/tex]
There are other square of binomial patterns (though the difference of squares pattern isn't really a square of binomial, I learned these three at the same time)
[tex](a+b)^2=a^2+2ab+b^2[/tex]
[tex](a-b)^2=a^2-2ab+b^2[/tex]

Answer:
Step-by-step explanation:
for the right side :
its a triangular prism and the volume is 4 x 8 x 10 = 320.
the SA is 10x4 divided by 2 x 2which is just 40.
8x5x2= 80 and
10x10= 100, so
the SA of the right figure is 220 in^2

Cecily claims that the equation y = mx + b, where b is a real number,
represents a function whose graph is a line. Which statement BEST
classifies this claim?
Cecily's claim is true only when b is zero.
Cecily's claim is true for all values of b.
Cecily's claim is not true for any value of b.
Cecily's claim is true only when b is not zero
Answer:
Cecily's claim is true for all values of b.
Step-by-step explanation:
Cecily's claim is true for all values of b.
If she graphs y = mx, and then y = mx + b, and then y = mx + c, and so on, she will find that her graphs are all straight lines that are parallel to each other (as they will all have the same slope, m).

A student ran out of time on a multiple choice exam and randomly guessed the answers for two problems. Each problem had 4 answer choices - a, b, c, d - and
only one correct answer. What is the probability that she answered neither of the problems correctly?
Write your answer as a fraction in simplest forme
Answer:
3/4
Step-by-step explanation:
2 problems consist 8 choices of answers.
the events for the correct answer are 2
and the events for incorrect answer are 6
so, the probability that she answered neither of the problems correctly = 6/8 = 3/4

what is the slope of a line containing points (2,-1) (3,5)
Answer:
slope(m)=6
Step-by-step explanation:
(2 , -1)=(x1 , y1)
(3 , 5)=(x2 , y2)
use formula : y2 - y1/x2 - x1
=5-(-1)/3-2
=5+1/1
=6/1
=6
therefore slope of a line is 6.

Question 10 of 10 To find the inverse of f(x) = 2x - 1, Patel begins by replacing f(x) with y. He then switches x and y. What is the next step? A. Replace y with f-1(x). B. Subtract 1 from both sides of the equation. C. Solve the equation for y. O D. Solve the equation for x. SUBMIT
Answer:
f⁻¹(x) = (x+1)/2
Step-by-step explanation:
Given the function f(x) = 2x - 1, we are to find its inverse;
Let y = f(x)
y = 2x - 1
Replace y with x
x = 2y - 1
Make y the subject of the formula
2y = x + 1
Divide both sides by 2
2y/2 = (x+1)/2
y = (x+1)/2
Replace y with f⁻¹(x)
f⁻¹(x) = (x+1)/2
Hence the required inverse is (x+1)/2
How much money should be deposited in an account today that earns 4% compounded monthly so that it will accumulate to $10,000 in 5 years?
Answer:
$8206.37
Step-by-step explanation:
According to the Question,
Given, Some money should be deposited in an account today that earns 4% interest Annually. but it is compounded monthly so (4/12)% Will be the new interest Rate .
Now, What Money Should be Invested For 5 years(60 months) to get $10000 in Return .
The Formula for Compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex] .
We have, r=4% , n=12 , t=5 & A=$10000 Put These all value in above equation.
[tex]10000=P(1+\frac{0.04}{12})^{60}[/tex]
[tex]P= \frac{10000}{1.0033^{60} }[/tex] ⇔ $8206.37 Should be invested .

FIND BD !!!!!!!!!!!!!!!!!!!!
BD = 2x-4
But it's also BE - CE + CD
BE is 3x-1
CE is 2x-3
CD is 2
so
BD = 3x-1 -(2x-3) +2
simplified
BD = 1x +4
since BD = BD (obviously), we can also say that the righthand sides of the two equation must be equal
2x -4 = 1x +4
let's solve for x and that put it into either of the 2 equations.
2x -4 = 1x +4
subtract 1x on both sides
x -4 = 4
add 4 on both sides
x = 8
substitute x for its value in 2x -4 = 1x +4
(this way we double check BD in two expressions at once. the equation should come out true, meaning same value for BD in each expression. both sides should be equal).
2*8 -4 = 1*8 +4
12 = 12
seems true
BD is safely 12

The base of triangle M is four times the base of tri-
angle N, while the height of triangle N is half the
height of triangle M. The area of triangle M is how
many times that of triangle N ?
Answer:
two times
Step-by-step explanation:
ΔM: let 'h' = height; let '4b' = base
ΔN: let 'h/2' = height; let 'b' = base
Area (ΔM) = 2bh
Area (ΔN) = bh

A cylindrical flower vase has a diameter of 6cm and a volume of 171cm^(3)
Determine the height of the vase.
Answer:
h = 6.05 cm
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
Pi, π = 3.14
Radius, r = diameter/2 = 6 cm/2
= 3 cm
Height, h = ?
Volume if the cylinder = 171 c ³
Volume of a cylinder = πr²h
171 = 3.14 * 3² * h
171 = 3.14 * 9 * h
171 = 28.26 * h
171 = 28.26h
h = 171/28.26
h = 6.0509554140127
Approximately,
h = 6.05 cm
