4. Factor (2a – b)^2- 4a^2
Answer:
(-b) (4a-b)
Step-by-step explanation:
(2a – b)^2- 4a^2
Let m = 2a-b
m^2 - (2a)^2
We know this is the difference of squares
x^2 - y^2 = (x-y)(x+y)
(m-2a) (m+2a)
Replace m with 2a -b
(2a -b-2a) (2a-b+2a)
Simplify
(-b) (4a-b)
Answer:
(4a - b)(-b)
Step-by-step explanation:
If we let x = 2a - b and y = 2a, our expression now looks like
[tex]x^2-y^2[/tex]
This kind of a expression is a common pattern in algebra called a difference of squares, and it can be factored like this (for a visual proof, see the attached image, courtesy of Great Maths Teaching Ideas):
[tex]x^2-y^2=(x+y)(x-y)[/tex]
Replacing x and y with 2a -b and 2a, our expression now becomes
[tex][(2a-b)+2a][(2a-b)-2a]\\=(2a-b+2a)(2a-b-2a)\\=(4a-b)(-b)[/tex]
So in factored form,
[tex](2a-b)^2-4a^2=(4a-b)(-b)[/tex]
The histogram shows the distributions of essay scores for high school sophomores and juniors in a contest. Which comparison of the distributions is true? Both distributions are nearly symmetric. Both distributions are right-skewed. The distribution of sophomores’ scores is right-skewed, and the distribution of juniors’ scores is left-skewed. The distribution of sophomores’ scores is left-skewed, and the distribution of juniors’ scores is right-skewed.
Both distributions are nearly symmetric. And the correct answer is A.
What is a distribution?The distribution of values in a field is described by a statistical distribution, often known as a probability distribution. In other words, the statistical distribution identifies the typical and unusual values. The bell-shaped normal distribution is one of many varieties of statistical distributions.
A histogram is a graphical illustration of information in bars of diverse heights.
A histogram displays the shape and spread of continuous sample data.
The true statements about the data of essay scores for high school sophomores and juniors in a contest are;
the juniors tended to have higher essay scores than the sophomores, the medians of both data sets are equal,
and the histogram is the best way to show that both distributions are nearly symmetric.
Therefore, distributions are symmetric.

Answer:
compounded quaterly
Step-by-step explanation:
hope this helps
plzz mark me brainliest
Answer:
Let's say:
AM = current amount of money = 3000
APR = interest rate = 2.25
n = number of compounding periods
t = 5 years
Final amount of money:
FAM = AM x [1 + 2.25/n]^(n x 5) = 3000 x [1 + 2.25/n]^(n x 5)
Annual Compounding: FAM = 3000 x (1 + (2.25% / 1))^(1 x 5) = 3353.03
Quarterly Compounding: FAM = 3000 x (1 + (2.25% / 4))^(4 x 5) = 3356.16
Monthly Compounding: FAM = 3000 x (1 + (2.25% / 12))^(12 x 5) = 3356.86
Continuous Compounding: FAM = 3000 x 2.7183^(2.25% x 5) = 3357.22
=>Continuous Compounding gives largest benefit.
=> Option C is correct
Hope this helps!

Solve for f.
-f + 2 + 4f = 8 - 3f
-f +2+4f = 8-3f
3f+2 = 8-3f
6f = 6
f = 1
Answer:
f = 1
Step-by-step explanation:
Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other.
Add 3f and subtract 2 from both sides:
-f + 2 (-2) + 4f (+3f) = 8 (-2) - 3f (+3f)
-f + 4f + 3f = 8 - 2
Simplify:
(-f + 7f) = 6
7f - f = 6
6f = 6
Isolate the variable, f. Divide 6 from both sides:
(6f)/6 = (6)/6
f = 6/6
f = 1
1 is your answer for f.

A meteorologist reports that the temperature today will be colder than −1° Fahrenheit. The inequality is t < −1. The variable t represents the temperature. A number line going from negative 2 to positive 2. Which numbers are solutions of the inequality? Choose all that apply. –2 0 1 –10 –3 –1
For the inequality t < -1, the numbers that are solutions to this inequality are -2, -3, and -10, as they are all less than -1.\
The inequality in question is t < -1, which indicates that the temperature (t) is colder than -1 degrees Fahrenheit. On a number line from -2 to +2, the numbers that satisfy this inequality would be all the numbers that are less than -1. Therefore, the solutions to the inequality would be the numbers that are to the left of -1 on the number line.
-2
-3
-10
The numbers 0, 1, and -1 do not satisfy the inequality because they are not less than -1.

That's the Riemann Zeta function. Here s is a complex number. If you can prove that all the non-trivial zeros of ζ(s) (which includes its analytic continuation to the entire complex plane) are on the line Re(s) = -1/2 then you will become a famous mathematician. You didn't even ask a question; not a very auspicious start, but don't give up.
If we restrict s to the reals, as Euler first did, we can prove there are an infinity of primes. Ever since the Zeta function has been closely related to the prime numbers.
One fun fact is ζ(-1) = -1/12, which has spawned lots of bad math claiming the sum of the natural numbers is -1/12,
[tex]-\dfrac{1}{12} = \zeta(-1) = \dfrac{1}{1^{-1}} + \dfrac{1}{2^{-1}} + \dfrac{1}{3^{-1}} + ... = 1 + 2 + 3 + 4 + ...[/tex]

what is the area of the square that shares a side with the third side of the triangle?
Step-by-step explanation:
Cuz sides of square are same, we just find hypotenusa side of triangle (use Phytagoras Theorem) :
c² = a² + b²
c² = 2² + 4²
c² = 4 + 16
c² = 20
c = √20
Side of square is √20 units.
The area of square :
A = s²
= √20²
= √20 × √20
= 20 units²
So, the area of square is 20 units²

If f(x) = 3x + 7, find:
f(3) = [ ? ]
Answer:
f(3) =16
Step-by-step explanation:
f(x) = 3x + 7
Let x= 3
f(3) = 3*3 +7
= 9+7
= 16
Answer: 16
Step-by-step explanation: f(x) = 3x + 7 means that if we put an x into our function, a 3x + 7 comes out.
So if we want to find f(3), we're putting a 3 into our function which means that a 3(3) + 7 comes out which simplifies to 9 + 7 or 16.
So f(3) = 16 or the value of the function at 3 equals 16.
A path through the middle of a circular garden is 14 feet long. [a] What is the distance around the outside of this garden? [b] What is the area of the garden? Use 3.14 for π.
Answer:
a. 43.96 feet
b.153.86 square feet
Step-by-step explanation:
Hi, the path through the middle of the circular garden is the diameter.
Since the diameter is equal to:
Diameter = 2 radius (r)
Solving for r
14 =2r
14/2 = r
r = 7 feet
The distance around the outside of this garden is the perimeter.
Perimeter of a circle (P) = 2 π r
Replacing with the values given:
P = 2 (3.14) 7 = 43.96 feet
b. area of the circle-
Area of a circle (A)= π r²
Replacing with the values given:
A = 3.14 (7²) =153.86 square feet

Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.
What is the probability of Sarah picking a blue marble on 2 consecutive draws without replacement?
15.8%
40%
20%
3.8%
The required probability of Sarah picking a blue marble on 2 consecutive draws without replacement is 15.8%. Option A is correct.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total marbles [sample space] = 100
Total favorable outcome = 40 = 40%
Now,
Picking another blues marble,
Total marble becomes 99 and the total favorable outcome becomes 39,
Probability of picking marble in two consecutive drawn,
= 40/100 × 39 / 99
= 0.158
= 15.8%
Thus, the required probability of Sarah picking a blue marble on 2 consecutive draws without replacement is 15.8%. Option A is correct.

Last softball season, Jenny hit 32% of the times she was at bat. If she had 80 hits, how many times was she at bat?
I think the answer is 26 because you have to take 32% of 80.
-Dhruva;)
Jenny was at bat 250 times.
What is the percentage?The percentage refers to a number that is out of 100. When describing components of a whole in mathematics, percentages are employed similarly to fractions and decimals. When employing percentages, the idea is that there are 100 equal pieces that make up the whole. In addition, the sign "%" is used to indicate that a number is a percentage. In stores, online, in commercials, and in the media, percentages are nearly always present. A crucial talent that may help you save time and money and raise your employability is the ability to comprehend what percentages represent.
Given jenny hit 32% of the time when she was at bat and also she had 80 hits. let's assume she had a total of x hits. so 32% of x will be equal to 80.
From that,
32% x = 80
32*x = 80 * 100
x = 250
Hence, Last season ball jenny was at bat 250 times.

If 5x² + 7x = 6, which statement is correct?
A)
X= 2 or x= 3/5
x = -2 or x= 3/5
x = 2 or x =-3/5
x = -2 or x = -3/5
Answer:
2nd choice: x = -2 or x= 3/5
Step-by-step explanation:
5x² + 7x = 6
We can solve.
5xx + 7x - 6 = 0
try the diamond method first
-30 = 5*-6.... -3*10 = -30 and -3x + 10x = 7x
So...
5xx - 3x + 10x - 6 = 0
x(5x - 3) + 2(5x - 3) = 0
(x +2)(5x - 3) = 0
roots x = -2 and x = +3/5
