The Washington Monument in Washington, D.C. is surrounded by a circle of 50 American flags that are each 100 feet from the base of the monument. The distance from the base of a flag pole to the top of the monument is 564 feet. What is the angle of elevation from the base of a flag pole to the top of the monument?
Answer:
Step-by-step explanation:
cosx=100/564
x=arccos(100/564)
x=79.79 degrees (to the nearest hundredth of a degree)
The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.
Calculation of the angle of elevation;Since there is 100 feet from the base of the monument.
And, The distance from the base of a flag pole to the top of the monument is 564 feet
Now the angle should be like
cosx = 100/564
x = arc cos(100/564)
x=79.79 degrees
hence, The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.

Step-by-step explanation:
A number is divided by 3 and decreased by 5 is 6. What is the number???
Answer:
Given : x/3-5=6
answer = 23
Step-by-step explanation:
x-5=6*3
x-5=18
x=18+5
x=23
Answer:
33
Step-by-step explanation:
let the number be n , then the number divided by 3 is [tex]\frac{n}{3}[/tex] and decreased by 5
[tex]\frac{n}{3}[/tex] - 5 = 6 ( add 5 to both sides )
[tex]\frac{n}{3}[/tex] = 11 ( multiply both sides by 3 )
n = 33
The number is 33
Use the Associative Property of Addition to write an expression equivalent to (u + 2) + 8.
Which expression is equivalent to (u + 2) + 8 by the Associative Property of Addition?
OA. U + 2 + 8
OB. 8+ (u + 2)
OC. (u + 8) + 2
OD. u + (2+8)
Answer:
D
Step-by-step explanation:
First of, associative property of addition is rearranging the parenthesis and not moving the numbers
A is incorrect because you can not take out the parenthesis in the equation
B is inccorrect because they change the position of the number
C is incorrect because they change the position of number
D is correct. It only change the position of the parenthesis
In the year 2005, a person bought a new car for $24500. For each consecutive year
after that, the value of the car depreciated by 9%. How much would the car be worth
in the year 2008, to the nearest hundred dollars?
Answer:
18500
Step-by-step explanation:
Percent decrease:
\text{Multiply by }(1-r)=(1-0.09)=(0.91)
Multiply by (1−r)=(1−0.09)=(0.91)
2005: \color{green}{24500}
2005:24500
2006: \color{green}{24500} (0.91) = \color{blue}{22295}
2006:24500(0.91)=22295
2007: \color{blue}{22295} (0.91) = \color{red}{20288.45}
2007:22295(0.91)=20288.45
2008: \color{red}{20288.45} (0.91) = \color{orange}{18462.49}
2008:20288.45(0.91)=18462.49

For f (x) = 2x+1 and g(x) = x2 - 7, find (fºg)(2).
Answer:
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8

A farmer recently sold a large plot of land. The sale decreased his total acreage by 6%. Let v be the original acreage. Find two equivalent expressions that will give the new acreage. Use the expressions to describe two ways to find the new acreage. Name two expressions that would give the new acreage. (A)0.06v
(B)6v
(C)v-6v
(D)0.94v-0.06v
(E)v-0.06v
(F)0.94v
Answer:
[tex]v - 0.06v[/tex] and [tex]0.94v[/tex]
Step-by-step explanation:
Given
[tex]Acreage = v[/tex]
[tex]Decrement = 6\%[/tex]
Required
Determine the new acreage
Because a reduction occur, the new acreage can be calculated using:
[tex]New = Acreage - Decrement * Avreage[/tex]
[tex]New = v - 6\% * v[/tex]
[tex]New = v - 0.06 * v[/tex]
[tex]New = v - 0.06v[/tex] ------ (1)
Evaluate the expression
[tex]New = 0.94v[/tex] ---- (2)

[tex]P_1=11.7\\P_2=15.21\\P_n=9\cdot1.3^n\\P_{10}\approx124.07[/tex]
Step-by-step explanation:
An exponential function can be written in the form ...
y = a·b^x
where x is the independent variable, b is the common ratio, and 'a' is the initial value (when x=0). The "common ratio" is the ratio of each term to the one before. For example, b = P₁/P₀.
Here, you are told the initial value (P₀) is a=9, and the common ratio is b=1.3. The independent variable is given as n, so your population formula is ...
P(n) = 9·1.3^n
__
You are asked for values when n = 1, 2, and 10. Since you know the common ratio, you can simply multiply P₀ by 1.3 to get P₁:
P₁ = 1.3·P₀ = 1.3·9 = 11.7
Similarly, ...
P₂ = 1.3·P₁ = 1.3·11.7 = 15.21
__
You could continue up to P₁₀, but it is easier to use a calculator to evaluate the exponential function.
P(10) = 9·1.3¹⁰ ≈ 124.07

There is a patch of lily pads on a lake. Every day, the patch doubles in size.
If it takes 48 days for the lily pads to cover the entire lake how much days does it take for the lily pads to cover half the lake.
Answer:
is it 47? I'm not sure
if not can you explain it to me
Answer:
47 days
Step-by-step explanation:
Since the patch of lily pads double each day, the day before day 48 would cover half of the lake.
those are currency exchange rates 1 us dollar = 7.76 hk dollars 1 us dollar =1.47 nk dollars work out the value of 1000 hk dollars in nz dollars
Answer: 1000 HK dollars has the same value as 188.15 NZ dollars.
Step-by-step explanation:
We know that:
1 US dollar = 7.76 HK dollars
1 US dollar = 1.46 NZ dollars.
We have 1000 HK dollars, and we want to know the value in NZ dollars.
First, let's rewrite the 1000 HK dollars in US dollars.
Here we use the relation:
1 US dollar = 7.76 HK dollars
Then:
1 = (1 US dollar/7.76 HK dollars)
Then we can write:
1000 HK = (1000 HK)*1 = (1000 HK)*( (1 US /7.76 HK ))
1000 HK = (1000 HK/7.76 HK)* 1 US = 128.87 US
1000 HK = 128.87 US
Now we can use the relationship:
1 US = 1.46 NZ
Then:
1 = (1.46 NZ)/(1 US)
So we can rewrite:
128.87 US = (128.87 US)*1 = (128.87 US)*( (1.46 NZ)/(1 US))
128.87 US = (128.87 US/1 US)*1.46 NZ = 188.15 NZ
Then:
1000 HK = 128.87 US = 188.15 NZ
So we can conclude that 1000 HK dollars has the same value as 188.15 NZ dollars.

---the system of simoultanious equation
X+2y+z=6
2x+y+2z=6
X+y+z=5
Answer:
The system of equations has no solution.
Step-by-step explanation:
Let the following system of linear equations:
[tex]x +2\cdot y + z = 6[/tex] (1)
[tex]2\cdot x + y + 2\cdot z = 6[/tex] (2)
[tex]x + y + z = 5[/tex] (3)
Since the quantity of equations and variables are the same, there is only one solution to this system. First, we clear [tex]x[/tex] in (3):
[tex]x = 5 - y - z[/tex]
And make substitution both in (1) and (2):
[tex](5-y-z) +2\cdot y + z = 6[/tex]
[tex]2\cdot (5-y-z)+y+2\cdot z = 6[/tex]
[tex]y = 1[/tex] (4)
[tex]y = 4[/tex] (5)
Which lead to a contradiction, since [tex]4\ne 5[/tex]. Therefore, the system of linear equations has no solution.

(2) the diagonals bisect each other
(3) opposite sides are congruent
(4) adjacent angles are supplementary
Would this be correct ladies and gents
Answer:
You can use the useful mnemonic: SOH CAH TOA to determine what function to use. Since we have information about the hypotenuse (H) and opposite (O), we should use sine (S) for "SOH".
So yes, sine would be correct.
