A person whose eyes are 5 feet above the ground is standing on the runway of an airport 100 feet from the control tower. That person spots one of the air traffic controller at the window of the 132 foot tall tower. What is the angle of elevation to the nearest tenth of a degree?
Answer:
132-5 therefore the height from the eyes to the window is 127
100 feet away from the base of the tower
This forms two legs of a triangle
trying to find the degrees of this triangle.
Since its the two legs, you can use tanx which = to opposite side/adjacent side
Therefore, it is tanx = 127/100
But you are looking for x so arctan(1.27)
Must use calculator to find x.
By rounding to one significant figure,estimate the answer to this question: 798 divided by 8 times 41 so I know it's 800 divided by 10=80 and 41 turns to 40 so it's 80x40 but no matter what I type in it's the wrong answer :/ just wanna make sure
Answer: Try this:
Step-by-step explanation:
798 rounded to one sig. fig. = 800.
8 is already just one sig. fig.
41 rounded to one sig fig. Is 40.
800/8x40
800/320 = 2.5.......
Rounded to one sig fig. =3
Or if you left the entire equation as is and just rounded the answer to 1 sig. fig.
798/(8x41) = 2.4329.......
rounded to one sig fig =2
Without knowing what specifically the question wants estimated to one significant figure, there could be multiple answers.
The estimate of the equation to one significant figure is 2.
What is a significant figure?Significant figures are the digits in a number that is significant and required to denote a value and also add to the correctness of that value.
The way we will solve this equation is to first determine the final value and then approximate it to 1 significant figure.
[tex]\mathbf{= \dfrac{798}{8 \times 41}}[/tex]
= 2.4329
≅ 2 (to one significant figure)

Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
Answer:
The amount Lilian needs to invest is $5,160
Step-by-step explanation:
The parameters of the amount Lilian is going to invest in an account are;
The interest rate the account pays = 5.7%
The final amount the investment is expected to reach after the given time period = $7,600
The number of years of the investment = 7 years
The formula for compound interest is presented as follows;
[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]
Where;
A = The final amount = $7,600
P = The amount Lilian is to invest
r = The interest rate = 5.7% = 0.057
n = The number of times the interest is applied per time period = 1
t = The number of period that passes = 7 (years)
Therefore, we get;
[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]
∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754
The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

Answer:
y= (x - 12)^3
y= (x - 4)^3
Step-by-step explanation:
Shift to the right is a horizontal shift so it needs to be with x in the parenthesis. And negative because it is to the right.
y= (x - 12)^3
y= (x - 4)^3
are the two that fit those criteria
Answer:
y = (x - 12)^3
y = (x - 4)^3
Step-by-step explanation:
If you look in the picture, red line is y = x^3 (the original parent equation), green line is y = (x - 4)^3, and blue line is y = (x - 12)^3

The polynomial 3x²+12x+14 cannot be factored by factoring out a GCF. Therefore, option D is the correct answer.
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
Here,
a) 9x²-81x+27
In the given trinomial, in each term 9 is the common factor, so, the GCF of the trinomial is 9.
Thus, 9(x²-9x+3)
b) 15x²+3x
The factors of each terms of binomial is listed below
15x²=3×5×x×x
3x=3×x
So, the GCF is 3x
Now, 3x(5x+1)
c) 2x+4
The factors of each terms of binomial is listed below
2x=2×x
4=2×2
So, the GCF is 2
Now, 2(x+2)
d) 3x²+12x+14
In this trinomial there is no common term.
Therefore, option D is the correct answer.

if the radius of the circle becomes two times what will be the new area of the circle
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.
