Answer:
Step-by-step explanation:
The current area is 60 sq. in. You wish to increase this area to 300 sq. in. by adding x in two dimensions: namely length and width.
These measurements would be 5 + x wide and 12 + x long.
(5 + x)(12 + x) = 300
x^2 + 17x + 60 = 300
Subtracting 300 from both sides and using the quadratic formula for
x^2 + 17x - 240 = 0,
we find that the one reasonable answer for the measure x is 9.2 inches.

f(x)=x2 g(x)=– 3x+1 Write your answer as a polynomial or a rational function in simplest form.
The simplest form of the polynomial is (x²)-3x+1.
A polynomial is a mathematical expression consisting of constants, variables, and exponents. It can be written in the form of a polynomial equation, which is a mathematical equation with one or more variables.
In this example, we have two functions, f(x) and g(x). The polynomial of these two functions can be written in simplest form by combining the functions together.
The polynomial of f(x) and g(x) is written in simplest form as (x²)-3x+1.
This means that for any value of x, the polynomial will evaluate to the value given by the equation.
If x=2, then the polynomial will evaluate to (2(2)²)-3(2)+1=3.

What is the arc measure of major arc BAC in degrees?
Answer:
arc BAC = 276°
Step-by-step explanation:
the sum of the angles around point D is 360°
sum the central angles and equate to 360
7n + 12 + 6n + 13n - 16 = 360
26n - 4 = 360 ( add 4 to both sides )
26n = 364 ( divide both sides by 26 )
n = 14
Then
∠ ADB = 7n + 12 = 7(14) + 12 = 98 + 12 = 110°
∠ ADC = 13n - 16 = 13(14) - 16 = 182 - 16 = 166°
• the arc of a circle is equal to the central angle it subtends
arc BA = ∠ ADB = 110°
arc AC = ∠ ADC = 166°
Then
arc BAC = arc BA + arc AC = 110° + 166° = 276°
Can you help me figure out the equation

g- given that a part produced in the plant is defective, what is the probability that it went through an electronic inspection?
The probability that a defective part went through an electronic inspection is 0.2058 or approximately 20.58%.
In order to find the probability that a defective part went through an electronic inspection, Bayes' Theorem will be used. The theorem states that the conditional probability of event A given event B can be calculated as:
P(A | B) = P(B | A) × P(A) / P(B)
where P(A) is the prior probability of event A, P(B | A) is the conditional probability of event B given event A, and P(B) is the overall probability of event B.
In this case, event A is the part that went through an electronic inspection, and event B is the part that is defective. The prior probability of a part going through an electronic inspection is:
P(A) = 0.15, and the overall probability of a part being defective is P(B) = 0.15 × 0.97 + 0.85 × (1 - 0.15) = 0.14695.
The conditional probability of a part being defective given it went through an electronic inspection is P(B | A) = 0.03. The probability of a part that went through an electronic inspection given it's defective is:
P(A | B) = P(B | A) × P(A) / P(B) = 0.03 × 0.15 / 0.14695 = 0.2058
So, the probability that a defective part went through an electronic inspection is 0.2058 or approximately 20.58%.

3(x - 5) - 7 = 2 true?
Answer:
x=8
Step-by-step explanation:
We can first take out 3(x-5) and expand it into: (3*x) + (3*-5) = 3x-15
Now, let's plug it into the original equation:
3x-15-7 = 2
Let's solve for x:
3x = 2+15+7

A circle has a circumfrence of 75.4, what is the diameter?
The diameter of the circle is 24 units.
What is a circle:In geometry, the circle is a curved and closed polygon whose boundary line is at equidistance from a point called the center.
A diameter is a line drawn through the circle's center and joining two points on its circumference. The diameter of a circle is twice its radius
The circumference of a circle is known as the circle's perimeter and is the distance a circle travels around its boundary line.
The formula for the circumference of a circle is given by
Circumference of circle = 2πrHere we have
The circumference of a circle is 75.4 units
Let 'r' be the radius of the circle
As we know Circumference of a circle = 2πr
=> 2πr = 75.4
=> 2r(22/7) = 75.4
=> 2r = (75.4 × 7)/22
=> 2r = [527.8]/22
=> 2r = 23.99
=> 2r = 24 (approx)
Therefore,
The diameter of the circle is 24 units.

Claire says that the AA Criterion should be called the AAA Criterion. Explain why Claire might say this. Do you agree? Explain.
No, AA Criterion should not be called the AAA Criterion, because we need only two angles to be equal to prove the similarity.
What is AA criterion?According to the AA triangle similarity criterion, two triangles are considered similar if their three angles are identical to one another. Equi-angular triangles are comparable in a nutshell.
Since just two pairs of angles must be equal in order for the third pair to be automatically equal thanks to the angle sum property of triangles, the proper term for this criterion would then be the AAA(Angle-Angle-Angle) criterion. However, we refer to it as the AA criterion instead.
Hence, no, because we need only two angles to be equal to prove the similarity.

A rectangular room is 6 meters longer than it is wide, and its perimeter is 36
meters. Find the dimension of the room.
TH
L
Step-by-step explanation:
length = width + 6
the perimeter of a rectangle is
2×length + 2×width
by using the first equating as identity in the second we get
36 = 2×(width + 6) + 2×width =
= 2×width + 12 + 2×width = 4×width + 12
24 = 4×width
width = 6 m
length = width + 6 = 6 + 6 = 12 m
he dimensions of the rectangular room are 6 meters by 12 meters of the rectangular room is 6 meters longer than it is wide, and its perimeter is 36 meters by solving equations and geometric measurements.
Given that the room is 6 meters longer than it is wide, we can represent the width as W. Therefore, the length of the room would be W + 6.
The perimeter of a rectangle is calculated by adding all four sides, which in this case is given as 36 meters. We can express this as an equation:
Perimeter = 2 * (Length + Width)
Substituting the values, we get:
36 = 2 * (W + (W + 6))
Simplifying the equation further, we have:
36 = 2 * (2W + 6)
Dividing both sides of the equation by 2, we get:
18 = 2W + 6
Subtracting 6 from both sides, we obtain:
12 = 2W
Dividing both sides by 2, we find:
W = 6
Now that we have the width, we can calculate the length:
Length = Width + 6 = 6 + 6 = 12
Therefore, the dimensions of the rectangular room are 6 meters by 12 meters of the rectangular room is 6 meters longer than it is wide, and its perimeter is 36 meters by solving equations and geometric measurements.
