What is the equation of the line that is perpendicular to
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
[tex]y = \stackrel{\stackrel{m}{\downarrow }}{-\cfrac{3}{4}}x+6 ~~ \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
therefore then
[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{-3}{4}} ~\hfill \stackrel{reciprocal}{\cfrac{4}{-3}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{4}{-3}\implies \cfrac{4}{3}}}[/tex]
so we're really looking for the equation of a line whose slope is 4/3 and passes through (3 , 9)
[tex](\stackrel{x_1}{3}~,~\stackrel{y_1}{9})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{4}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{9}=\stackrel{m}{\cfrac{4}{3}}(x-\stackrel{x_1}{3}) \\\\\\ y-9=\cfrac{4}{3}x-4\implies y=\cfrac{4}{3}x+5[/tex]

Geometry is so hard help me!
Answer:
x = 2√5
Step-by-step explanation:
Isosceles right angle triangles have two congruent sides ( for more reference , kindly check the attached image ) making it a special 45-45-90 degree triangle.
Special triangles have simple easy rules to help identify the lengths of the other sides lengths. For the 45-45-90 degree triangle, the hypotenuse (longest side) is equal to the value of the triangles leg(shorter sides) times √2 ( for more reference kindly check the other attached image )
Here, the value of the leg it equal to √10
If the value of the hypotenuse (x) = leg × √2
Then the value of x = √10 × √2
x = √10 × √2 = √(10 × 2) = √20
==> simplify radical
x = 2√5
prove fermat's last theorem:no three positive integers a, b, and c satisfy the equation a^n + b^n = c^n for any integer value of n greater than 2
The proofing of Fermat's last theorem shows that y = a² - b², z = a² + b² and x = 2ab.
How to prove fermat's last theorem?The equation x² + y² = z². We can assume that x, y, and z are positive and relatively prime. Suppose that x is even. Then:
(z - y/2)(z + y/2) = (x/2)²
Hence,
(z - y)/2 = b²
(z + y)/2 = a²
Then, y = a² - b², z = a² + b² and x = 2ab.

1. Are the side lengths congruent?
2. Are the opposite sides parallel?
3. Are the adjacent sides perpendicular?
Answer:
1:If three pairs of sides of two triangles are equal in length, then the triangles are congruent. ASA (angle-side-angle): If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent. 2:All sides are equal in length. Diagonals bisect each other at a 90-degree angle. The sum of any two adjacent interior angles is 180 degrees. Opposite sides are equal and parallel to each other.3:Each pair of opposite sides is parallel, and adjacent sides are perpendicular. This means that every angle in a rectangle is a right (90∘) angle.

(b) Explain how can you define ſ so that it is continuous at x=0?
b
(a)The domain of the function is, [tex]\rm x \geq -c^2 \ x\neq0[/tex]
(b)The given function is discontinuous at x=0.
What is the domain and range of a function?
Domain is the set of values for which the given function is defined. Range is the set of all values which the given function can output.
The standard function is;
[tex]\rm f(x)= \frac{\sqrt{x+c^2-c} }{x} , c > 0[/tex]
The domain of the given function is found as;
[tex]\rm x+c^2 \geq 0 \ x\neq 0 \\\\ x\geq-c^2 \ x\neq 0[/tex]
The domain of the function is,
[tex]\rm x \geq -c^2 \ x\neq0[/tex]
To find the function is continuous or not, we have to find the continuity;
[tex]\rm f(x) = \frac{\sqrt{ x+c^2-c}}{x} ,c > 0[/tex]
At x= 0 the function is undefined. So that the function is discontinuous at x=0.
Hence, The domain of the function is, [tex]\rm x \geq -c^2 \ x\neq0[/tex] and the function is discontinuous at x=0.

- In the 1940s, the U.S. Department of Commerce reported a new way to test the tensile
strength, in pounds per square inch, of concrete. Several samples of concrete specimens
were used to estimate the mean tensile strength of 430 pounds per square inch with a
margin of error of 10 pounds per square inch. After the study was published, another
group proposes to run the same test on concrete specimens but with samples including
many more concrete specimens in each sample. (2 points)
Which of these statements is most likely to be true about the second study?
A. The estimated mean will be greater than 440 pounds per square inch.
B. The margin of error for the second study will likely be around 10 pounds per square inch.
C. The margin of error for the second study will likely be greater than 10 pounds per square inch.
D. The margin of error for the second study will likely be less than 10 pounds per square inch.
Using the Central Limit Theorem, it is found that the statement that is likely to be true about the second study is given by:
D. The margin of error for the second study will likely be less than 10 pounds per square inch.
What does the Central Limit Theorem states?It states that the sampling distribution of sample means of size n has standard error [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
That is, higher sample sizes leads to lower amounts of error, and since the second study has a higher sample size, it should have lower error, hence option D is correct.

Suppose you roll a special 9-sided die. What is the probability that the number rolled is a "1" OR a "2"?
Answer:
P(1 or 2) = 2/9
Step-by-step explanation:
OR means we add each probability
If it is 9-sided, I will assume the die will be numbered 1-9
Probability of getting a 1 in mathematical notation is:
P(1) = 1/9
Probability of getting 2:
P(2) = 1/9
We add their probabilities since we want to know if we get either 1 or 2
P(1) + P(2) = 1/9 + 1/9 = 2/9
If the question asked what the probability was of getting a 1 and a 2 by rolling the die twice, we would multiply the probabilities together
1/9 x 1/9 = 1/81

7. Hunter has a choice between 2 pizzas: a circular pizza with a 10-inch diameter, and a square pizza with a 9-inch side. Which statement below is true? O The pizzas have the same area. The area of the square pizza is larger. The area of the circular pizza is 100 square inches The area of the circular pizza is larger.
Answer:
(b) The area of the square pizza is larger
Step-by-step explanation:
The areas can be computed using the appropriate formulas, then compared.
__
circular pizzaA = πr² . . . . . r = half the diameter
A = π(5 in)² = 25π in² ≈ 78.5 in²
square pizzaA = s² . . . . . s is the side length
A = (9 in)² = 81 in²
The area of the square pizza (81 in²) is larger than that of the circular pizza (78.5 in²).
binomial distribution
Answer:
Using the binomial distribution, it is found that
P(X > 3) = 0.0256
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, with p probability.
[tex]P(X = x) = C_{n, x} * p^{x} (1 - p)^{n- x }[/tex]
[tex]C_{n, x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n, x} = \frac{n!}{p!(n - x)!}[/tex]
Binomial distribution:In this question, we have that n = 4, p = 0.4The desired probability is:P(X > 3) = P(X = 4) since it above next whole number above 3
In which
[tex]P(X = x) = C_{n, x} * p^{x} (1 - p)^{n- x }[/tex]
[tex]P(X = 4) = C_{4, 4} * (0.4)^{4} (1 - 0.4)^{4 - 4}\\C_{4, 4} = \frac{4!}{4!(4 - 4)!}\\\\P(X = 4) = \frac{4!}{4!(0)!} * (0.4)^{4} (0.6)^{0}\\[/tex]
Then
P(X > 3) = P(X = 4)
P(X > 3) = 0.0256

A percent is a rate in which the first term is compared to ______
Answer:
From what we know about percentages and unit rates, the correct options are:
1) 100
2) 1
What is a percent?
Suppose we have an amount A, this would be the 100%.
If we want to know how much a quantity B represents, compared to A, we have:
A = 100%
B = x
where x is a percentage, to find the value of x we compute:
x = (B/A)*100%
While there is a dependence on A, we actually are comparing the term with 100 (because A represents a 100%), so the correct option is A: 100

A machine uses pieces of tape to seal packages. It cuts the tape Into pieces exactly 2.375 Inches long. If It uses 4 pieces of tape for a package,
how many packages can it seal with a roll of tape 1,900 Inches long?
OA
200 packages
OB. 400 packages
OC 600 packages
OD.
800 packages
Answer:
A. 200 packages
Step-by-step explanation:
The number of packages per roll can be found by dividing the length of a roll by the length of tape needed for each package.
__
For each package:
(2.375 in/piece)×(4 piece/package) = 9.5 in/package
Per roll:
(1900 in/roll) / (9.5 in/package) = (1900/9.5) packages/roll
= 200 packages/roll
The machine can seal 200 packages with a roll of tape 1900 inches long.

0.65
Assuming that the availability of cherries and the availability of asparagus are
independent of each other, which market should Elena choose to maximize
her chance of buying both?
O A. South market. There is a 0.77 probability of both cherries and
asparagus being available.
B. North market. There is a 0.77 probability of both cherries and
Elena should go to the south market because there is 0.52 probability of both cherries and asparagus being available.
How to determine the market to choose?The table is given as:
North market South market
Cherries 0.96 0.8
Asparagus 0.5 0.65
The probability of buying both produce at both markets is calculated as:
P(North) = 0.96 * 0.5 = 0.48
P(South) = 0.8 * 0.65 = 0.52
0.52 is greater than 0.48
Hence, Elena should go to the south market because there is 0.52 probability of both cherries and asparagus being available.
