1. Which statement correctly describes the perpendicular bisector construction below?
Answer:
option c is correct....
Suppose g ( x ) = √ x − 3 / x − 11 . what is the domain of g?
The domain of the function g ( x ) = √ x − 3 / x − 11 is R - 11.
What does a function's domain entail?Inputs are assigned outputs by functions. The collection of all potential inputs for a function is its domain. For instance, the domain of f(x)=x2 and g(x)=1/x are all real integers with the exception of x=0.
How do you determine a function's domain?Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.

how to find f (8)
Answer:
f(8) = -208
Step-by-step explanation:
Apply 8 into the equation
f(8) = -3(8)² - 2(8)
= -192 - 16
= -208
8 will be your x value since it's implied within the question itself.
Answer:
-208
Step-by-step explanation:
Given function:
[tex]\text{f}(x)=-3x^2-2x[/tex]
To find f(8), substitute x = 8 into the function:
[tex]\begin{aligned}\text{f}(x) & =-3x^2-2x\\\implies \text{f}(8) & =-3(8)^2-2(8)\\& =-3(64)-2(8)\\& =-192-16\\& = -208\end{aligned}[/tex]

Find the measures of complementary angles with measures 9x+6 and 3x degress
Step-by-step explanation:
As we know that the value of Complementary angle is always 90°
9x° + 6° + 3x° = 90°
12x° + 6° = 90°
12x° = 90° - 6
12x° = 84°

No, 12 17 and 14 19 determined ratio are not proportional.
What are proportional ratios?If two ratios depict the same connection, they are said to be proportionate. By writing two ratios as fractions and then reducing them, one may determine if they are proportionate. Your ratios are proportional if the reduced fractions are equal.
We can observe that 17 and 19 are prime numbers,
So, 12 : 17 cannot be simplified further,
Neither 14 : 19 can be simplified.
⇒ 12 : 17 ≠ 14 : 19

Pretty sure I answered this before, but here you go.
Quotient means The answer when you divide' So we are working in the division.
n ÷ 4 is the division part
It says 'and' which can also mean addition. So we add 6. So far our equation is: (n ÷ 4) + 6 (Brackets are needed as we are dividing n by 4 and not dividing n by 4+6)
Lastly it says the answer must be 8 so we add that at the end. So the answer is:

1.2 A pyramid, with the base similar to an obtuse-angled triangle as indicated by the diagram below. A = 110°, B = 40° and BC = 6 meters. The perpendicular height of the pyramid is 8 meters
1.Calculate the length of AB
2.Calculate the area of the base.
3.Calculate the volume of the pyramid
a) The length of the side AB is approximately 11.276 meters.
b) The area of the base of the pyramid is approximately equal to 6.161 square meters.
c) The volume of the pyramid is equal to 16.429 cubic meters.
What are the length of a side, the surface area and the volume of a pyramid?a) The picture shows a pyramid with a triangular base, the triangle has one obtuse angle and the length of the side AB can be found by the law of the sine:
6 / sin 110° = AB / sin 30°
AB = 6 × (sin 30° / sin 110°)
AB ≈ 3.193 meters
The length of the side AB is approximately 11.276 meters.
b) First, find the length of the side AC:
6 / sin 110° = AC / sin 40°
AC = 6 × sin 40° / sin 110°
AC ≈ 4.104 meters
Second, determine the area of the triangular base by Heron's formula:
s = 0.5 · (AC + BC + AB)
s = 0.5 · (4.104 m + 6 m + 3.193 m)
s = 6.649 m
A = √[s · (s - AC) · (s - BC) · (s - AB)]
A = √[6.649 · (6.649 - 4.104) · (6.649 - 6) · (6.649 - 3.193)]
A ≈ 6.161 square meters
The area of the base of the pyramid is approximately equal to 6.161 square meters.
c) The volume of the pyramid can be found by using the following expression:
V = (1 / 3) · A · h
Where:
A - Area of the pyramid base, in square meters.h - Height, in meters.If we know that A ≈ 6.161 square meters and h = 8 meters, then the volume of the pyramid is:
V = (1 / 3) · (6.161 m²) · (8 m)
V = 16.429 m³
The volume of the pyramid is equal to 16.429 cubic meters.

Area of rectangle = length × width
= 6 × 3
= 18m²
Area of semi circle = 180/360 × π × radius²

motorcycle maker, says that it expects to build 312,000 motorcycles this year, up from 290,700 last year. Find the percent of increase in production.
Explanation:
A = last year's value = 290,700
B = this year's value = 312,000
C = change in values
C = B - A
C = 312,000 - 290,700 = 21,300
The positive result shows the increase of 21,300 more motorcycles made this year, compared to last year. A negative C value would represent a percent decrease.
Divide this change over the original.
C/A = (21,300)/(290,700) = 0.07327141382869
which is approximate. Let's say we rounded to four decimal places to get 0.0733 which then converts to the percentage 7.33%
