You could do this step by step.
The first year is left alone: 90,000 kt
The second year is 90000 * 0.96 That represents a 4% reduction
Second year = 86400
Third year = 86400 * .96 = 82944
Fourth year = 82944 * 0.96 = 79626.24 Here's where you run into your first dilemma. What do you do with that 0.24? The answer is, you round it here, but leave it in your calculator.
Fourth year = 79626
Fifth year = 79626.24 * 0.96
Fifth year = 76441
Sixth year = 79626.1904 * 0.96
Sixth year = 73383.542
Sixth year = 73384
Of course once you have gone through all that, you could do it this way
Sixth year = 90000 * 0.96^(n - 1) = 73383.54 = 73384
Same answer both ways.
I'm going to leave the addition to you.
Sum = a* (r^(n) - 1)/ (r - 1)
Sum = 90000 * (0.96^5 - 1) / (0.96 - 1 ) = 415411 rounded. I think that's right, but check it out.

Write the expression for 2 added to the product of a number p and 43
Answer:
43p + 2
Step-by-step explanation:
Product of p and 43 = 43p
2 added to the product of p and 43 = 43p + 2
Answer:
Step-by-step explanation:
The product of a number p and 43 means
p * 43 = 43p
And 2 added to the product gives;
43p + 2
However; the expression is 43p + 2.

x + 3 > 70
How do I solve this step by step?
Answer:
x > 67
Step-by-step explanation:
x+3 >70
subtract from each side
x+3-3 > 70 -3
x > 67
Algebra
To solve this, simplify the algebra inequality.
Subtract three from both sides.
x>67
Meaning, x is bigger than 67.
HELP ASAP !! Which is more, 1 mile or 365 yards?
Answer:
1 mile is longer than 365 yards
Step-by-step explanation:
there are 1,760 yards in a mile
Hi there!
»»————- ★ ————-««
I believe your answer is:
One mile.
»»————- ★ ————-««
Here’s why:
A mile is 1,760 yards. Since the number of yards given in the question, 365, is less than 1,760, a mile would be more than 365 yards. Side note: 365 yards is about 0.2 of a mile.»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.

In a 30-60-90 special right triangle, if long leg is 5√3 then the short leg = ___, and the hypotenuse is ____
Answer:
short = 5, hypotenuse = 10
Step-by-step explanation:
In a 30-60-90 triangle, the long leg is x√3, the short leg is x, and the hypothenuse is 2x.
As the long leg is 5√3, we can see that x is 5. So, the short leg would be 5 and the hypothenuse would be 2x5, which is 10.

Mike and Sarah are packing boxes at a factory. Mike packs 30 boxes each hour. Sarah packs 15 boxes each hour. How many boxes will each person have packed after an 8 hour shift?
Answer:
Mike= 240 boxes
Sarah= 120 boxes
Step-by-step explanation:
Mike and Sarah are packing boxes at a company
Mike packs 30 boxes each hour, after an 8 hour shift the number of boxes he will pack is
= 30×8
= 240
Sarah packs 15 boxes each hour, afterr an 8 hour shift the number of boxes she will pack is
= 15×8
= 120
Hence after the 8 hours shift Mike will pack 240 boxes while Sarah will pack 120 boxes
The center of circle Q has coordinates (3,-2). If circle Q passes through R(7,1), what is the
length of its diameter?
A. 50
B. 25
C. 10
D. 5
Answer:
C.
Step-by-step explanation:
We can use the distance formula to find the distance between the center of circle Q and point R, which is also the radius of the circle. Then, we can multiply this value by 2 to get the diameter of the circle.
Distance Formula:
The distance between two points with coordinates (x1, y1) and (x2, y2) is given by the formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Using the distance formula, we can find the radius of circle Q:
radius = sqrt((7 - 3)^2 + (1 - (-2))^2)
= sqrt(4^2 + 3^2)
= 5
Therefore, the diameter of the circle is:
diameter = 2 * radius
= 2 * 5
= 10
So, the length of the diameter of circle Q is 10 units.

Which type of graph would be best for displaying the frequencies of weights of several juvenile monkeys at a wild animal preserve according to equal-sized weight categories?
A. a bar graph
B. a circle graph
C. a histogram
D. a line graph
Answer:
C. A histogram
Step-by-step explanation:
Histograms are commonly used to denote the frequency of a range of categories of a set of values. Generally, the y-axis represents frequency and the x-axis represents intervals of data based on the given set of values.
Which values of x would make a polynomial equal to zero if the factors of the
polynomial were (x+4) and (x+8)?
A. 4 and -8
B. 4 and 8
O c. -4 and -8
O D. -4 and 8
Answer:
C
Step-by-step explanation:
Given the factors of a polynomial.
To find the zeros ( the values that make the polynomial equal to zero ), then
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x + 8 = 0 ⇒ x = - 8
Find the value of the term in the arithmetic sequence using an = a^1+ (n-1)d. 3,5,7,9,11, (8th term)
=========================================================
Work Shown:
a1 = 3 = first term
d = 2 = common difference (since we add 2 to each term to get the next one)
Let's compute the nth term.
an = a1 + (n-1)*d
an = 3 + (n-1)*2
an = 3 + 2n-2
an = 2n+1
-----------------------
To check things so far, we can plug in something like n = 2
an = 2n+1
a2 = 2*2+1
a2 = 5
Showing that the 2nd term is 5, which matches with the sequence given to us
Let's check n = 3
an = 2n+1
a3 = 2*3+1
a3 = 7
That matches as well. I'll let you check the others.
-----------------------
Plug in n = 8 to find the 8th term
an = 2n+1
a8 = 2*8+1
a8 = 17
The eighth term is 17, which is the final answer.
-----------------------
You could extend out the given sequence by adding 2 each time until you reach the 8th term
3,5,7,9,11,13,15,17
Though this method is slow if you need to find say the 38th term
Answer:
17 is the answer for the value of the term in the arithmetic sequence using the above

Find the equation of a circle with a center at (7,2) and a point on the circle at (2,5)?
Answer:
[tex](x-7)^2+(y-2)^2=34[/tex]
Step-by-step explanation:
We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).
First, recall that the equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
Since our center is at (7, 2), h = 7 and k = 2. Substitute:
[tex](x-7)^2+(y-2)^2=r^2[/tex]
Next, the since a point on the circle is (2, 5), y = 5 when x = 2. Substitute:
[tex](2-7)^2+(5-2)^2=r^2[/tex]
Solve for r:
[tex](-5)^2+(3)^2=r^2[/tex]
Simplify. Thus:
[tex]25+9=r^2[/tex]
Finally, add:
[tex]r^2=34[/tex]
We don't need to take the square root of both sides, as we will have the square it again anyways.
Therefore, our equation is:
[tex](x-7)^2+(y-2)^2=34[/tex]

What is the y-intercept of a line that has a slope of 2 and passes through point (8,3)?
1
3
5
11
Answer:
the y intercept is -13
Step-by-step explanation:
First of all we need the line equation so let's find it first :
y = mx + b
y = 2x + b
_______________________________
The line passes through point ( 8 , 3 ) which means if put 8 instead of x the y must equals to 3 :
2(8) + b = 3
16 + b = 3
b = 3 - 16
b = - 13
______________________________
Now we have the equation of the line :
y = 2x - 13
To find the y-intercept we just need to out 0 (zero ) instead of x ; Let's do it :
y = 2(0) - 13
y = 0 - 13
y = - 13
Thus the y-intercept = - 13
