Answer: C complete reversal
Step-by-step explanation:
When there is a complete reversal error which is also known as an " error of complete reversal entry", the debit entry is switched with the credit entry. This is one of the more difficult errors to pick up because the Trial balance remains balanced when this happens as the debits and the credits would still be equal.
When rent is received from a tenant. The correct entries are to debit it to cash which is an asset and so will be debited when it increases.
Then credit it to Rent Receivable because this is a revenue account and these are credited when they increase.
The entries were therefore reversed.

Both boxes are -20.25
Step-by-step explanation:
The y-value for the vertex is when you plug in the x-value of the vertex in. The vertex is at (2.5, -20.25). SInce the vertex is the lowest or highest point on a parabola, the range is y>=-20.25.
the polygons in each pair are similar. find the scale factor of the smaller figure to the larger figure.
Answer:
Smaller factor/larger figure = 3/6 = ½
Step-by-step explanation:
Scale factor of similar figures is usually the ratio of one to the other.
In the diagram given, the scale factor is the length of any side of the smaller figure divided by the length of the corresponding side length of the bigger figure.
Length of smaller figure = 3
Corresponding length of larger figure = 6
Scale factor = smaller figure/larger figure = 3/6
Simplify
Scale factor = ½

A geometric series has three terms. The sum of the three terms is 42. The third term is 3.2 times the sum of the other two. What are the terms?
Answer is : 2,8, and 32
Please show steps because I'm very confused
Let x be the first term in the geometric sequence. Then the next two terms in the sequence are xr and xr ², where r is some constant. (This is the defining characteristic of geometric sequences.)
The sum of the first three terms is 42, so
x + xr + xr ² = 42
x (1 + r + r ²) = 42
The third term is 3.2 times the sum of the other two, so that
xr ² = 3.2 (x + xr )
Solve the second equation for r :
xr ² = 3.2 x (1 + r )
We can divide both sides by x since x ≠ 0. (This is obvious, since if x was zero, then all three terms in the sequence would be 0.)
r ² = 3.2 (1 + r )
r ² = 3.2 + 3.2r
r ² - 3.2r - 3.2 = 0
r ² - 16/5 r - 16/5 = 0
5r ² - 16r - 16 = 0
(5r + 4) (r - 4) = 0
==> r = -4/5 or r = 4
Since there are two possible values of r that might work, there are two possible sequences that meet the criteria.
Plug either of these solutions into the first equation:
r = -4/5 ==> x (1 + (-4/5) + (-4/5)²) = 42
… … … … … … 21/25 x = 42
… … … … … … x = 50
r = 4 ==> x (1 + 4 + 4²) = 42
… … … … … 21x = 42
… … … … … x = 2
Then the two possible answers would be
• if r = -4/5, then the three terms are {50, -40, 32}
• if r = 4, then they are {2, 8, 32}
Answer:
Step-by-step explanation:
A geometric series means that we multiply one number by a common ratio to get the second number. Let's say our first number is x, and our common ratio is y. We can write the first term is x, and to get the second number, we multiply x by our common ratio, y. For example, if 5 was the first number and 2 was the common ratio, the second number would be 5*2 = 10, and the third would be 10 * 2 = 20.
For our question, the first number is x, the second is x*y, and the third is x*y*y = x*y²
The sum of these three terms is 42, so we can say
x + x*y + x*y² = 42
Next, the third term is equal to 3.2 times the sum of the other two. First, we have 3.2 times something. That something is the sum of the other two, so we must prioritize calculating the sum of the first two numbers, and then multiply that by 3.2 to get the third. We can write this as
(x + x*y) * 3.2 = x*y²
factor out x
x * 3.2(1 +y) = x*y²
divide both sides by x
3.2(1+y) = y²
expand
3.2 + 3.2y = y²
subtract (3.2 + 3.2y) from both sides to make this a quadratic equation
y²-3.2y-3.2 = 0
use the quadratic formula to solve for y (note that +- here stands for "plus or minus")
[tex]y = \frac{-(-3.2) +- \sqrt{3.2^{2}-4(-3.2)(1)} }{2} \\= \frac{3.2+-\sqrt{10.24+12.8} }{2} \\= \frac{3.2+- 4.8}{2}[/tex]
= -0.8 or 4
With these two possibilities, we can try each in our other equation to see what works.
x + x*y + x*y² = 42
for y = -0.8
x + -0.8x + 0.64x = 42
x - 0.16x = 42
0.84x = 42
multiply both sides by 1/0.84 to isolate the x
x=50
This works, with x (the first number) =50, the second number being 50 * -0.8 = -40, and the third being -40 * -0.8 = 32. 50+(-40) = 10, 10*3.2=32, and 50-40+32 = 42
Next, for y=4, we have
x+4x + 16x= 42
21x = 42
divide both sides by 21 to isolate the x
This works as well, with x=2, the second value being 2*4 = 8, and the third value being 8*4 =32. 2+8=10, 10*3.2 = 32, and 2+8+32 = 42

Find the value of z such that 0.04 of the area lies to the left of z. Round your answer to two decimal places.
Answer: The value of z is -1.75.
Step-by-step explanation:
Given: P(Z<z)=0.04
To find the value of z such that 0.04 of the area lies to the left of z.
We will use z-score table to get the value of z here.
IN z-score table, we have
For P(Z<-1.7507)=0.04
Hence, the value of z is -1.7507.
Its approximate value is -1.75
So the final answer is z=-1.75.

The rocket reaches its greatest height at
feet after
second(s)
Answer:
Step-by-step explanation:
This is most easily solved with calculus, believe it or not. It is way more direct and to the point, with a whole lot less math!
The position function is given. The velocity function is the first derivative of the position, so if we find the velocity function and set it equal to 0, we can solve for the amount of time it takes for the rocket to reach its max height. Remember from physics that at the top of a parabolic path, the velocity is 0.
If:
[tex]s(t)=-16t^2+112t+360[/tex], then the velocity function, the first derivative is:
v(t) = -32t + 112 and solve for t:
-112 = -32t so
t = 3.5 seconds. Now we know how long it takes to get to the max height, we just need to find out what the max height is.
Go back to the position function and sub in 3.5 for t to tell us that position of the rocket at 3.5 seconds, which translates to the max height:
[tex]s(3.5)=-16(3.5)^2+112(3.5)+360[/tex] and
s(3.5) = 206 feet. I imagine that your answer, if you had to choose one from the list, would be 200 feet, rounded a lot.

3. Given the graph below, determine whether each statement is true or false.
Answers:
TrueTrueTrueFalseFalse======================================
Explanation:
In this context, a zero is another term for x intercept or root. This is where the graph either touches or crosses the x axis. This occurs in three locations: x = -3, x = 2, and x = 0. So those are the three roots. That makes the first three statements true, while the remaining two others are false.
Side note: x = 0 doesn't always have to be involved. Its quite possible to have x = 0 not be an x intercept. The term "zero" is a bit misleading in that regard. I prefer either "root" or "x intercept" instead.

Step-by-step explanation:
cos theta = adj / hyp
We can find the opp by using the Pythagorean theorem
adj^2 + opp ^2 = hyp^2
10^2 +opp^2 = 17^2
100 + opp^2 = 289
opp^2 = 289-100
opp^2 = 189

opp = sqrt(189)
opp = 3 sqrt(21)
Since we are in the first quad, opp is positive
sin theta = opp /hyp
sin theta = 3 sqrt(21)/17
Using a secant and a tangent, find angle WVT.
Answer:
[tex]m\angle WVT=40^{\circ}[/tex]
Step-by-step explanation:
When two secants or a secant and a tangent of a circle intersect outside the circle, the measure of the acute angle formed is equal to half of the positive difference of smaller and larger arc formed.
Therefore, we have the equation:
[tex]m\angle WVT=\frac{1}{2}(\widehat{TW}-\widehat{UW}),\\3x+4=\frac{1}{2}(14x+7-(7x+11))[/tex]
Distribute:
[tex]3x+4=\frac{1}{2}(14x+7-7x-11),\\\\3x+4=\frac{1}{2}(7x-4),\\\\3x+4=3.5x-2[/tex]
Add 2 to both sides and subtract [tex]3x[/tex] from both sides:
[tex]6=0.5x[/tex]
Divide both sides by 1/2:
[tex]x=\frac{6}{\frac{1}{2}}=6\cdot 2=12[/tex]
Now substitute [tex]x=12[/tex] into [tex]3x+4[/tex]:
[tex]m\angle WVT=3(12)+4,\\m\angle WVT=36+4,\\m\angle WVT=\boxed{40^{\circ}}[/tex]
