Flipping a point across the y axis, the y coordinate should flip signs (negative if it was positive before, and vice versa). So
reflection across y axis = (-1 5/7, 1).
Similarly, reflecting across the x axis, the sign will also flip. So
reflection across x axis = (1 5/7, -1).

1.) The plane left LaGuardia Airport at 3:25 pm and, about two minutes later, struck a flock of birds. The plane had
travelled four miles from LaGuardia and was ascending at an angle of elevation of 7.7°. Calculate the plane's
height above ground level at the time of the bird strike to the nearest tenth of a foot.
The plane still climbed in altitude for 19 more seconds after the bird strike even after it lost thrust in both engines,
reaching a maximum height of 3060 ft.
2.) In order to reach its maximum height of 3060 ft., the plane had to increase its altitude by 242 ft and travel a
horizontal distance of 7150 ft.
(a) Calculate the distance the plane had to travel in order to increase its altitude by 242 ft. Round your answer
to the nearest tenth of a foot.
(b) Find the angle of elevation (to the nearest hundredth of a degree) at which the plane climbed during this
time interval. You do not have to draw a diagram to answer this part of the question.
3.) At this point, the plane started to descend. As the plane turned, its altitude dropped from 3060 feet to 1650 feet
above ground level. Calculate the angle of depression at which the plane descended to the nearest hundredth of
a degree if the horizontal distance it travelled was 0.5 miles.
4.) The plane continued to descend, but leveled off to an angle of depression of 3º.
(a) If the plane descended for two miles diagonally, how many feet (to the nearest tenth) did it drop in
b) Using the information provided in problem 3 and your answer to part (a) of problem 4, find the new
altitude of the plane at this time. Show your work.
5.) At this point, the plane crossed over the George Washington Bridge and landed in the Hudson River at an angle
of depression of 2º. From the time the plane crossed over the bridge to the time it landed in the river, it travelled
3.5 miles horizontally.
(a) By how many feet (to the nearest tenth) did the airplane descend in altitude during this time interval?
(b) Using the information from problem 4(b) and problem 5(a), find the new height of the plane (in feet) after
its descent.
(c) If the bridge is 212 feet above the water, by how many feet did the airplane clear the bridge? Show your
work.
(d) Air Traffic Control at La Guardia Airport reported seeing the aircraft pass less than 900 feet above the
George Washington Bridge. Do your calculations support this statement? Explain

Answer: He invests $470 and the balance is $517 at the end of 2 years
Answer:
$470
$517
Step-by-step explanation:
Simple interest formula: A = P(1 + rt)
where A is the final amount, P is the principal amount, r is the annual rate interest (in decimal form), t is time (in years)
Zachary invests $400 into an account that earns 3.5% simple interest for 5 years. So the account balance at the end of 5 years will be:
P = 400
r = 3.5% = 3.5/100 = 0.035
t = 5
⇒ A = 400(1 + 0.035 x 5) = 400 (1.175) = 470
So Zachary has $470 in his account after 5 years.
Now he is investing $470 into an account for 2 years earning 5% interest. So the new account balance at the end of 2 years will be:
P = 470
r = 5% = 5/100 = 0.05
t = 2
⇒ A = 470(1 + 0.05 x 2) = 470(1.1) = 517

Relaciona el número con su lectura. Luego,selecciona la respuesta correcta
De acuerdo con la información presentada se puede inferir que la relación entre los números y letras es 1b, 2d, 3a, y 4c (opción a)
¿Qué es un número entero?Los números enteros son todos los números que pertenezcan a la categoría de los números naturales. Adicionalmente, se incluyen sus opuestos negativos incluyendo el número cero (0).
De acuerdo con lo anterior, debemos asociar los números con la forma correcta de escribirlos. Primero debemos tener en cuenta el número que está antes de la coma.
Por ejemplo el primer número solo puede relacionarse con las opciones B y D, debido a que estos comienzan con el 3.
Posteriormente, nos fijamos en el número que está después de la coma que en el caso del primer número sería cuatro mil ciento cinco millonésimos. Entonces el número 1, se asociaría con la letra b.
Entonces la opción 2 se debe relacionar con la opción restante que dice tres, antes de la coma, es decir, la opción d.
En cuanto a las opciones que comienzan con el 32, antes de la coma realizamos el mismo procedimiento de fijarnos en el número que está después de la coma. En el caso del número 3. tiene el número cuatrocientos un mil cinco millonésimas después de la coma, entonces sería la opción A.
Por último, la única opción que queda sería la opción C que se relaciona con el número 4.

Notice that both ⌊x/2⌋ and ⌈2/x⌉ are integers, so they must be divisors of 17. But 17 is prime, so either
⌊x/2⌋ = 1 and ⌈2/x⌉ = 17
or
⌊x/2⌋ = 17 and ⌈2/x⌉ = 1
Let x = 2y for some real number y.
• Suppose ⌊x/2⌋ = 1 and ⌈2/x⌉ = 17. Then by definition of floor and ceiling,
⌊x/2⌋ = ⌊2y/2⌋ = ⌊y⌋ = 1 ⇒ 1 ≤ y < 2 ⇒ 2 ≤ x < 4
and
⌈2/x⌉ = ⌈2/(2y)⌉ = ⌈1/y⌉ = 17 ⇒ 16 < 1/y ≤ 17 ⇒ 2/17 ≤ x < 1/8
but this is impossible.
• Suppose ⌊x/2⌋ = 17 and ⌈2/x⌉ = 1. Then
⌊x/2⌋ = ⌊y⌋ = 17 ⇒ 17 ≤ y < 18 ⇒ 34 ≤ x < 38
and
⌈2/x⌉ = ⌈1/y⌉ = 1 ⇒ 0 < 1/y ≤ 1 ⇒ 2 ≤ x
The solution set is the intersection of these two intervals, which is
34 ≤ x < 38
Edit: 17 can also be factorized as (-1) × (-17), so we have two more cases to consider:
• If ⌊x/2⌋ = -1 and ⌈2/x⌉ = -17, then
⌊x/2⌋ = ⌊y⌋ = -1 ⇒ -1 ≤ y < 0 ⇒ -2 ≤ x < 0
⌈2/x⌉ = ⌈1/y⌉ = -17 ⇒ -18 < 1/y ≤ -17 ⇒ -2/17 ≤ x < -1/9
so that -2/17 ≤ x < -1/9 is also a solution.
• If ⌊x/2⌋ = -17 and ⌈2/x⌉ = -1, then
⌊x/2⌋ = ⌊y⌋ = -17 ⇒ -17 ≤ y < -16 ⇒ -34 ≤ x < -32
⌈2/x⌉ = ⌈1/y⌉ = -1 ⇒ -2 < 1/y ≤ -1 ⇒ 2 ≤ x < 4
but this is also impossible.

O cos-1
Answer:
our answer will be in quadrant 1 only.
Step-by-step explanation:
From the
cos−1(1) we have the side adjacent to ∠θ=1 and the side hypotenuse=2 . So this is a 30∘−60∘−90∘ triangle and θ=60∘therefore the opposite to ∠θ=√3.
Note that from the restrictions for the range of inverse circular functions cos−1x is restricted to quadrants 1 and 2 and since the argument is positive 12 our answer will be in quadrant 1 only.
The equation that can be used to find the measure of angle BAC is [tex]A = \tan^{-1}(\frac{12}5)[/tex]
To find the measure of angle BAC, we make use of the following tangent ratio
[tex]\tan(A) = \frac{12}5[/tex]
Next, we take the arc tan of both sides
[tex]\tan^{-1}(\tan(A)) = \tan^{-1}(\frac{12}5)[/tex]
So, we have:
[tex]A = \tan^{-1}(\frac{12}5)[/tex]
Hence, the equation that can be used to find the measure of angle BAC is [tex]A = \tan^{-1}(\frac{12}5)[/tex]

A new car is purchased for $47, 000 and over time its value depreciates by one half
every 4.5 years. What is the value of the car 23 years after it was purchased, to the
nearest hundred dollars?
Answer:
$1500
Step-by-step explanation:
you can figure it out by going in increments of 4.5 years because that is the info you have from the problem so
47000 4.5 years later is 23500
9 years = 11750
13.5y = 5875
18y = 2937.5
22.5 years later is 1468.75
22.5 years is about 23 years and to the nearest hundred dollars that is $1500 so that is the answer
Hope this helps! :)
we know the car depreciates every 4.5 years, and we also know its by one half or namely the depreciation rate is 50% of its value.
