What is the length of DC? Show work.
Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:
[tex] \frac{AD}{AC} = \frac{AE}{AB} [/tex]
Plug in the values
[tex] \frac{9}{9 + DC} = \frac{12}{12 + 4} [/tex]
[tex] \frac{9}{9 + DC} = \frac{12}{16} [/tex]
[tex] \frac{9}{9 + DC} = \frac{3}{4} [/tex]
Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3

A company sells widgets. The amount of profit, y, made by the
company, is related to the selling price of each widget, x, by the given
equation. Using this equation, find out the maximum amount of profit
the company can make, to the nearest dollar.
y = -4x^2 + 183x – 1247
Answer:
846.06 units
Step-by-step explanation:
The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :
[tex]y = -4x^2 + 183x- 1247[/tex] ...(1)
We need to find out the maximum amount of profit the company can make.
For maximum profit put dy/dx = 0
So,
[tex]\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87[/tex]
Put x = 22.87 in equation (1). So,
[tex]y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06[/tex]
So, the maximum profit is 846.06 units.

Charlie made $198 for 11 hours of work. At the same rate, how many hours would he have to work to make $126?
Answer:
Charlie would have to work 7 hours to make $126.
Step-by-step explanation:
198 ÷ 11 = 18
$18 - 1 hour
126 ÷ 18 = 7

What is the volume of a rectangular prism whose length is 2x+1 units, width is x-2 units, and whose height is 3x units?
6x^3-9x^2-6x cubic units
6x^2-9x-6 square units
6x^3-9x^2+6x cubic units
6x^3-15x^2+6x cubic units
Answer:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
Step-by-step explanation:
The volume of a rectangular prism of length L, depth W and height H is
V = L * W * H.
Thus,
in this case,
V = (2x + 1)(x - 2)(3x).
The order in which we multiply these quantities together is immaterial.
Working from left to right, we get:
V = (2x^2 - 3x - 2)(3x), and then:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)

Answer:
Option B
Step-by-step explanation:
Scale factor by which the triangle ABC has been dilated to form the image triangle DEF,
Scale factor = [tex]\frac{\text{Dimension of image triangle}}{\text{Dimension of the original triangle}}[/tex]
= [tex]\frac{EF}{BC}[/tex]
= [tex]\frac{1}{2}[/tex]
Therefore, Option B will be the correct option.
Joey ate 3/5 of a pizza and Rachel ate 2/3 of a pizza. About how much pizza did they eat altogether? Show and explain how you estimate how much pizza they ate.
Answer:
The answer is 1 4/15 of a pizza.
Step-by-step explanation:
You have to change both fractions to their least common denominator. 3/5 would = 9/15 and 2/3 would equal 10/15. You add the two together and you get 19/15 or
1 4/15.

The chance of rain is 20%, the chance of it being sunny is 60%, and the chance of it
being sunny and rainy at the same time is 10%. Calculate, the probability that it is
either sunny or rainy.
Answer:
0.6 = 60% probability that it is either sunny or rainy.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Event A: Rain
Event B: Sun
The chance of rain is 20%
This means that [tex]P(A) = 0.2[/tex]
The chance of it being sunny is 60%
This means that [tex]P(B) = 0.6[/tex]
The chance of it being sunny and rainy at the same time is 10%.
This means that [tex]P(A \cap B) = 0.1[/tex]
Calculate, the probability that it is either sunny or rainy.
This is:
[tex]P = P(A) + P(B) - 2P(A \cap B) = 0.2 + 0.6 - 0.2 = 0.6[/tex]
0.6 = 60% probability that it is either sunny or rainy.
State one of the De Morgan’s laws for Logic
In set theory, De Morgan's Laws relate the intersection and union of sets through complements. In propositional logic, De Morgan's Laws relate conjunctions and disjunctions of propositions through negation. De Morgan's Laws are also applicable in computer engineering for developing logic gates.
ABC has vertices A(2,3), B(4,6), C(7,4) Describe a sequence of two transformations that would move ABC to Quadrant III.
Answer:
Some examples
Step-by-step explanation:
1.The vertices of triangle ABC are A(2,-3), B(-3,-5), and C(4,1). For each translation, give the vertices of triangle A'B'C'. When the transformation (-2,3). When the T (-4,-1) and T
C
2.Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three medians of triangle ABC
Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three altitudes of the same triangle
Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three perpendicular bisectors of the same triangle.
A(−3, 0), B(0, 6), and C(4, 6)
using the midpoint formula: we can find all of their midpoint which is necessary to complete question 1 and 2
Mid AB=(-1.5, 3), Mid BC=(2, 6), Mid AC=(0.5,3)
Next, we have to find the slope of from the vertex and the midpoint of each side. We use the slope formula: .
You would get -6, 6/5, and 6/11.
Next you substitute in the coordinates for the equation of each for example: y=-6x, you switch in the set of cords AB which is (-1.5, 3). 3=-6(-1.5)+z and find that z=6, so the equation is y=-6x+6. As for the rest, repeat the same process until you find all 3 cords. You should get an answer of
For question 2,
The line has to be perpendicular bisector to the midpoint, signifying that it has to split 2 angles into congruent angles and a side into half. In order to do that we need to first find the opposite reciprocal of each side's slope. Which means we need to once again use the slope formula and get the opposite reciprocal by . For all the opposite reciprocal slopes you get will be incorporated into the final formulas. That gives us the slopes of -1/2, 0 and -7/6.

-6x+5y=1 and 6x+4y=10.substitution
Answer:
(23/27, 11/9)
Step-by-step explanation:
Given the simultaneous equation;
-6x+5y=1..... 1
6x+4y=10.... 2
Add both equations
5y + 4y = 1+10
9y = 11
y = 11/9
Substitute y = 11/9 into 1;
From 1;
-6x+5y=1.
-6x + 5(11/9) = 1
-6x + 55/9 = 1
-6x = 1- 55/9
-6x = (9-55)/9
-6x = -46/9
x = -46/-54
x = 23/27
The solution to the system of equation is (23/27, 11/9)
