I’m trying to figure out the domain and range of this, could someone explain and give the answer? Thank you
Answer:
The domain is all the possible inputs for this function. The range is all the possible outputs for this function.
The line starts at the x-value of 0 and ends at the x-value of 12. Therefore, your domain is D: [0, 12].
The line starts at the y-value of 9000 and ends at the y-value of 0. Therefore, your range is R: [0, 9000].

Need someone who’s really good at math to help me please!! Suppose you buy 3500 worth of furniture for a new house. The furniture store is offering a fixed installment loan with three year financing with no money down at 11.96% annual interest. What is the monthly payment? Round to nearest cent.
Answer:
monthly payment $132.11
Step-by-step explanation:
Interest = Principal x Rate x Time
I = 3500(.1196)(3)
I = 1255.80
Amount = Principal + Interest
A = 3500 + 1255.80
A = 4755.80
Monthly payment = 4755.80 / 36 months = $132.11 monthly

3 ÷ 60% = 5
Alan worked 5 hours on the project.
What is a percentage?A percentage is a proportion or value that may be expressed as a fraction of 100. Furthermore, the notation "%" is used to denote it.
Let H be the hours he worked on the model.
Alan spent 3 hours building a model for his science project. This was 60% of the total time he spent on the project.
To find the H;
we use the percentage property,
3 = H x 60 / 100
H = 300 /60
H = 5 hours.
Therefore, 5 hours he worked on the project.

List the key features of the quadratic equation y = x2 + 6x - 16.
A. x-intercepts: (-8,0) and (2,0), y-intercept: (0,–16), vertex: (-3,-25).
B. X-intercepts: (-8,0) and (2,0), y-intercept: (0,–6), vertex (-3,-25).
C. X-intercepts: (8,0) and (-2,0), y-intercept: (0.-16), vertex: (-3,-25).
D. x-intercepts: (-8,0) and (2,0), y-intercept: (0,16), vertex: (-3,-25).
Answer:
Correct choice is A
Step-by-step explanation:
Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The x-intercepts are the points where the graph of the function crosses the x-axis, they are also called zeros or roots. They can be found by solving the equation y=0,
The y-intercepts are the points where the graph of the function crosses the y-axis. They can be found by setting x=0.
We are given the function:
[tex]y = f(x)=x^2+6x-16[/tex]
Find the y-intercept. x=0:
[tex]f(0)=0^2+6*0-16=-16[/tex]
y-intercept: (0,-16)
Find the x-intercepts, y=0. Solve the equation
[tex]x^2+6x-16=0[/tex]
Factoring:
[tex](x-2)(x+8)=0[/tex]
Which gives x=2, x=-8.
X-intercepts (2,0) (-8,0)
This leaves us only choice A as correct. But we'll compute the vertex also.
Completing squares:
[tex]y=x^2+6x-16=x^2+6x+9-16-9=(x+3)^2-25[/tex]
Comparing with the vertex form of the function, we have: h=-3, k=-25, thus the vertex is located at (-3,-25)
This confirms that the correct choice is A
2 A sample of two items is selected without replacement from a batch. Describe the (ordered) sample space for each of the following batches: a. The batch contains the items {a, b, c, d}. b. The batch contains the items {a, b, c, d, e, f , g}. c. The batch contains 4 defective items and 20 good items. d. The batch contains 1 defective item and 20 good items.
Answer:
a.{a b, a c, a d, b c, b d, c d, b a, d c ,d b, c a, d a, c b}
b.{a b, a c, a d, a e ,a f, a g, b c, bd,be,bf,bg,cd,ce,cf,cg,fg,ba,ca,da,ea,fa,ga,cd,db,eb,fb,gb,dc,ec,fc,gc,fe,ge,gf,de,df,dg,ed,fd,gd,ef,eg}
c.{d d, dg, g d, g g}
d.{dg, g d, gg}
Step-by-step explanation:
We have to find the sample space
a. We are given items
{a, b, c, d}
Therefore, the sample space
{a b, a c, a d, b c, b d, c d, b a, d c ,d b, c a, d a, c b}
b. Items
Therefore, the sample space
{a b, a c, a d, a e ,a f, a g, b c, bd,be,bf,bg,cd,ce,cf,cg,fg,ba,ca,da,ea,fa,ga,cd,db,eb,fb,gb,dc,ec,fc,gc,fe,ge,gf,de,df,dg,ed,fd,gd,ef,eg}
c.
Defective items (d)=4
Good items(g)=20
Therefore, the sample space
{d d, dg, g d, g g}
d.
Defective items (d)=1
Good items(g)=20
Therefore, the sample space
{d g, g d, g g}

If BD bisects AC and AC bisects BD, is ABE ≅ CDE? Explain.
A. Yes; the triangles are congruent by AAS.
B. Yes; the triangles are congruent by ASA.
C. Yes; the triangles are congruent by SAS.
D. No; the triangles are not congruent.
Answer:
C. Yes; the triangles are congruent by SAS.
Step-by-step explanation:
From the question, we understand that:
AC and BD bisects one another
The bisection is better illustrated with a diagram. (See attachment).
From this point, I'll use the attachment as a point of reference.
From the attachment:
[tex]AE = CE[/tex] --- Side
and
[tex]BE = DE[/tex] --- Side
When both lines bisect one another, they form a pair of vertical angles [tex]\angle AEB[/tex] and [tex]\angle CED[/tex]
When we apply the theorem of vertical angles to this, we have that:
[tex]\angle AEB[/tex] [tex]=[/tex] [tex]\angle CED[/tex] --- Angle
At this point, we have established:
Two sides of ABE and CDE are congruent
and
One angle in each of ABE and CDE are also congruent
Hence, the triangles are congruent by SAS.

The hanger image below represents a balanced equation
Answer:
9.1 = a + 4
Step-by-step explanation:
Equations
If the hanger image represents a balanced equation, then the left and the right 'weights' on the hanger must be equal.
On the left side, there is a weight of 9.1, and on the right side, the weight is a+4. Balancing the hanger, we obtain the required equation:
9.1 = a + 4
Answer:
the equation would be 9.1 = a + 4

The formula for the volume of a right cylinder is V = (pi)r^2h. Find the rate of change of the volume when r = 2 inches if dr/dt = 1/8 in./min and h = 5r. Show all your work.
Answer:
The volume is increasing at a rate of 15π/2 squared inches per minute.
Step-by-step explanation:
The formula for the volume of a right cylinder is:
[tex]V=\pi r^2h[/tex]
We want to find dV/dt when r = 2, dr/dt = 1/8 in/min, and h = 5r.
Since h = 5r:
[tex]V=\pi(r)^2(5r)=5\pi r^3[/tex]
Differentiate both sides with respect to t:
[tex]\displaystyle \frac{dV}{dt}=15\pi r^2\frac{dr}{dt}[/tex]
Since r = 2 and dr/dt = 1/8:
[tex]\displaystyle \frac{dV}{dt}=15\pi(2)^2\Big(\frac{1}{8}\Big)=\frac{15\pi}{2}[/tex]
So, the volume is increasing at a rate of 15π/2 squared inches per minute.
What is the length of the line TR
Answer:
15
Step-by-step explanation:
If the other triangle is part of the problem the triangle increased by 2.5
2.5 * 6 is 15
so 15 is the length of TR
Answer:
[tex]\Large \boxed{\sf 15}[/tex]
Step-by-step explanation:
Both triangles are similar so the two corresponding sides are proportional.
[tex]\displaystyle \frac{4}{6} =\frac{10}{TR}[/tex]
[tex]TR= 15[/tex]

Tan(F) = x/y
Step-by-step explanation:
Tan(F) = opposite Side / Adjacent side. The hypotenuse is not involved.
The opposite side is the side that you hit when drawing a line inside F to DE
The Adjacent side is one of the lines forming angle F.
Opposite side = x
Adjacent side = y
Tan(F) = x/y
