Answer:
654 grams
Step-by-step explanation:
When you set up this equation you want the number of grams you start with, 2616, and the factor by which it is decreasing, which is half, or 1/2. Because the half life is 11 days, but you want to find the amount left over after 22 days, you can make 22/11 as the exponent on the 1/2. The equation should look like this : 2616(1/2)^22/11. With these kinds of equations you always want to multiply the starting value by the factor of increase/decrease, and raise that factor to the time eclipsed divided by the set time(like the 11 day half life).

Algebraically, find the roots of x² - 4x - 5=0.
Algebraically, find the roots of x² - 4x - 5 = 0
Solution:-x² - 4x - 5 = 0 (Given equation)
Here a = 1, b = -4 and c = -5
[tex] \therefore [/tex] b² - 4ac = (-4)² - (-4) × 1 × -5 = 16 - 20 = -4 < 0
There are no real roots for the given equation. [Answer]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.

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,

Answer:
12) m∠BXD = 122°
13) m∠GXE = 50°
Step-by-step explanation:
12) m∠BXD = ∡BXC + ∡CXF + ∡FXD = 32° + 50° + 40° = 122°
13) m∠GXE = (90° - m∠AXG) = 90° - 40° = 50°
How can you use transformations to graph this
function?
y=3.75 +2
Explain your steps.
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.

CW: If the 5th term and the 10th term of an arithmetic
sequence is 44 and 89 respectively, what is the value of the
21st term? (show your work for a full mark)
Answer:
a₂₁ = 188Step-by-step explanation:
The n-th term of an arithmetic sequence: [tex]a_n=a_1+d(n-1)[/tex]
so:
[tex]a_5=a_1+d(5-1)\\a_5=a_1+4d\\a_1=a_5-4d\\a_1=44-4d\\\\a_{10}=a_1+d(10-1)\\ a_{10}=a_1+9d\\89=44-4d+9d\\45=5d\\d=9\\\\a_1=44-4\cdot9 = 8\\\\a_{21}=a_1+ 20d=8+20\cdot9=188[/tex]

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?
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.

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.
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

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
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)
