Answer:
[i] 12x + 5 = 1/2(83 +95)
12x + 5 = 89
12x = 84
x = 7.
[ii] 9x + 7 = 1/2(198 + 7x - 8)
18x + 14 = 198 + 7x - 8
11x = 176
x = 16.
[iii] 15x - 8 = 1/2(16x +1 + 5x + 19)
30x16 21x + 20
9x = 36
x = 4.
[iv] 20x - 4 = 360 - 2 × 72
20x = 220
x=220/20=11°
[v] 13x - 1 = 2(6x + 11)
13x - 1 = 12x + 22
x = 23.
[vi] 46 = 1/2(21x-5-x-23)
20x2892
20x = 120
x = 6.
[vii] 6x - 21 = 1/2(13x - 3-3x - 11)
12x - 4210x - 14
2x = 28
x = 14.
[viii] 2x + 1 = 1/2(9x − 14 − 4x + 7)
4x + 2 = 5x - 7
x = 9.
[ix] 9x - 4 = 180 - 76
9x - 4 = 104
9x = 108
x = 12.

Determine if the side lengths listed create a right triangle, acute triangle, obtuse triangle, or do not make a triangle. 3, 9, 10 Determina si las longitudes de los lados enumeradas crean un triángulo rectángulo, un triángulo agudo, un triángulo obtuso o no forman un triángulo. 3, 9, 10 * 1 point right acute obtuse not a triangle
Answers
Answer:
Obtuse triangle
Step-by-step explanation:
Given the side lengths :
3, 9, 10
Let :
a = 3 ; b = 9 ; c = 10 (longest side)
If a² + b² = c² (right angle)
If a² + b² > c² (acute angle)
If a² + b² < c² (obtuse angle)
a² + b²
3² + 9²
9 + 81 = 90
c² = 10² = 100
90 < 100
Hence,
a² + b² < c² (then we have an obtuse triangle)

An ant stands atop a grassy hill looking at a castle. A horizontal bridge 20 feet long crosses the gap, forming a right angle with the castle wall. The hill slopes down to a moat (water) that is 10 feet wide. The moat has 0 alligators because this is a math problem, not Louisiana. The castle is 38 feet tall, measuring from moat to roof.
a) Draw a sketch showing all the information you have right now.
b) The angle of elevation from the ant to the castle roof is 54.5°. Find the height of the castle above the bridge to the nearest foot (whole number).
c) What is the distance of the vertical drop from the bridge into the moat?
d) Find the angle between the hillside and the underside of the bridge. You may assume that the hill's slope is perfectly straight.

Suppose you invest $34,600 into a savings account with a 11.25% annual interest rate
that compounds interest semi-annually. Use the TVM solver on your calculator to find the
future value of the account after ten years.
Answers
Answer:
$103,373.81
Step-by-step explanation:
The calculation of the future value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
where,
rate of interest = 11.25% ÷ 2 = 5.625%
And, the number of years is = 2 × 10 = 20
Therefore, the future value is
= $34,600 × (1 + 5.625%)^20
= $34,600 × 2.987682472
= $103,373.81

You are paying off a student loan in monthly installments. After
the 4rd payment the remaining balance is $13,900. After the 5th
payment your remaining balance is $13,500. If n is the number of
payments that have been made, what is the nth term rule?
Answers
Answer:
The loan will be paid after 39 monthly installments.
Step-by-step explanation:
Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:
13900 - 13500 = 400
400 x 5 = 2000
2000 + 13500 = 15500
15500/400 = 38.75
Thus, the loan will be paid after 39 monthly installments.
Julio has $150. Each week, he saves an additional $10.Write a function ()that models the total amount of money Julio has after weeks.

Answer:
The function that models the total amount of money Julio has after weeks is:
f(x)=150+10x, where:
x is the number of weeks
Step-by-step explanation:
With the information provided, you can say that the total amount of money Julio has would be equal to the initial amount he has plus the result of multiplying the $10 that he saves every week for the number of weeks, which can be expressed as:
f(x)=150+10x, where:
x is the number of weeks
Answer: f(x)=150+10x,

How can you use transformations to graph this
function?
y=3.75 +2
Explain your steps.
Answers
Answer:
Sketch the graph of y=7^x
Reflect the graph across the y-axis to show the function y=7^-x
Stretch the graph vertically by a factor of 3 to show the function y=3*7^-x
Shift the graph up 2 units to show the function y=3*7^-x+2
Step-by-step explanation:
Answer: Draw a graph showing y=7x. The graph can be reflected across the y-axis to display the function y=7x-x. To display the function y=3*7-x, multiply the graph's vertical extent by 3. The graph should be moved up 2 units to display the function y=3*7-x+2.
