Step-by-step explanation:
an account transaction log is simply a sequence of basic additions and subtractions.
he made a mistake in line 4 : $180 - $188 = -$8 and not $8.
he missed that this was going below zero and needed a "-" sign.
from there on everything else is wrong too (although the individual calculations are correct) - the balances are off by $16 (2×8 from -8 to +8) :
+$20 gave the real balance of $12 and not $28.
-$5.95 gave the real balance of $6.05 and not $22.05.

Write an equation of the circle with center (7, 6) and radius 5.
Answers
Answer:
( x-7)^2+(y-6)^2 = 25
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2
where ( h,k) is the center and r is the radius
( x-7)^2+(y-6)^2 = 5^2
( x-7)^2+(y-6)^2 = 25
Answer:
(x-7)^2+(y-6)^2=25
Explanation:
If I were you, I would mark 7 as x and 6 as y. Whatever is in your parenthesis for center of the circle, do the opposite in your equation. Since you have positive 7 & positive 6, turn those into negative numbers for your equation. And for the radius, just times it two times. So 5•5=25
What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
Answers
The simplified value of the exponential expression is 2.
How to get the simplified expression?
Here we need to simplify the expression:
[tex]16^{1/4}[/tex]
First, you need to remember that:
[tex]\sqrt[n]{x} = x^{1/n}[/tex]
Then we can just write:
[tex]16^{1/4} = \sqrt[4]{16}[/tex]
And now, you can remember that:
2*2 = 4
Then:
2*2*2*2 = 4*4 = 16
From this, we can conclude that:
[tex]2^4 = 16\\\\\sqrt[4]{16} = 2[/tex]
So we conclude that the simplified value is 2.

Step-by-step explanation:
Concepts
The volume of any prism is represented as Bh, where B = Area of the Base and h = height of the prism.
Application
In this case, we're given the area of the base as five feet² and the height as 12 feet. Now, we just multiply these two numbers to get the volume.
Solution
12 × 560 feet³Which best describes independent events?
A. The results of all events have different individual probabilities.
B. The results of any previous events affects the probability of future events.
C. The results of all events have the same individual probability.
D. The results of all previous events do not affect the probability of future events.
Answers
The option that best describes independent events is the results of all previous events do not affect the probability of future events.
What are independent events?Independents events are events whose occurrence do not depend on each other. They are random events.
For example, there is no relationship between the the colour of shoes you wear and the chances that it would rain. Thus, they are independent events.

The side b is 2√6 unit
Step-by-step explanation:
in right triangle ΔABC,∠C=900,a=5,c=7;c is
the side opposite to the right angle, so it is hypotenuse,
aandb are the adjacent sides of the right angle .
We know in right triangle ΔABC,a²+b²=c²
∴5²+b²=7²or
b²=49−25=24
∴√b²=√24
b=√24
b=2√6
. The side b is 2√6 unit [Ans]
AB = 7 cm
CB = 5 cm
AC = 2√6cm
According to Pythagoras Theorem,
AC²=BC²+AB²
(2√6)²=5²+7²
24=25+49
24=74
Hence, it is not a right-angled triangle ABC.

The distance between the points (9, –6) and (–4, 7) will be 13√2. Then the correct option is C.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D² = (x - p)² + (y - q)²
The points are (9, –6) and (–4, 7). Then the distance will be
D² = (-4 - 9)² + (7 + 6)²
D² = 13² + 13²
D² = 169 + 169
D² = 338
D = √338
