An airplane flying at an altitude of 18,000 feet has just begun its descent, and it will descend at a rate of 450 feet per minute.
Which of these equations represents the airplane's altitude, y, in feet after it has been descending for x minutes?
A. y equals negative 450 x minus 18,000
B. y equals negative 450 x plus 18,000
C. y equals 450 x minus 18,000
D. y equals 450 x plus 18,000
Answer:
Choice B
y = -450x +18,000
Step-by-step explanation:
18,000 = b
descent rate = 450 = m
x = minutes

Answer:
A = 139.5 cm^2
Step-by-step explanation:
Ok, let's break it down into pieces. First let's find the area of the main rectangle. We know that the area of a rectangle is as follows:
A = L x W
A = 9 x 12
A = 108 cm^2
Now we need to find the area of the two triangles. There are two ways to approach this. If you can visualize that you can flip the first triangle and slide it against the second, it becomes a rectangle. Then you can simply use the same formula as before with modified numbers.
L = 7 (height of the triangle
W = 4.5 (base of the triangle (half of 9))
A (both triangles) = 7 x 4.5
A (both triangles) = 31.5 cm^2
If you can't quite figure out how to visualize that, you can simply treat them as two independent right triangles. The formula for the area of a right triangle is as follows:
A = (1/2)b x h
b = 4.5
h = 7
A (first triangle) = (1/2)4.5 x 7
A (first triangle) = 15.75 cm^2
The area of the second triangle is identical
A (second triangle) = 15.75 cm^2
The area of the two triangles added together is
A (both triangles) = A (first triangle) + A (second triangle)
A (both triangles) = 31.5 cm^2
As you can see we got the same answer both ways. Now we just have to add the area of the two triangles to the area of the rectangle
A = 108 + 31.5
A = 139.5 cm^2

Answer:
a) The golf ball reaches a height of 64 feet.
b) The golf ball will take 2 seconds to reach maximum height.
c) The golf ball will take 4 seconds to land after being hit.
d) The golf ball will be 48 feet above ground 1 and 3 seconds after being hit.
Step-by-step explanation:
a) The parabolic motion of the golf ball is described by a second order polynomial, that is, the equation of the parabola. To determine the maximum height of the golf ball, we need to transform the equation of the parabola given into vertex form:
[tex]h = -16\cdot (t^{2}-4\cdot t)[/tex]
[tex]h - 64 = -16\cdot (t^{2}-4\cdot t + 4)[/tex]
[tex]h - 64 = -16\cdot (t-2)^{2}[/tex]
From this form we can obtain relevant information of the maximum height of the golf ball, contained in the left side of the equation. On this approach, we conclude that the golf ball reaches a height of 64 feet.
b) The time taken by the golf ball is contained in the right side of the formula. That is, the golf ball will take 2 seconds to reach maximum height.
c) In this case, we need to factor the polynomial to find right times, that is:
[tex]h = 64\cdot t - 16\cdot t^{2}[/tex]
[tex]h = 16\cdot t \cdot (4 - t)[/tex]
The time taken by the golf ball to land is contained in the second binomial. In a nutshell, the golf ball will take 4 seconds to land after being hit.
d) If we know that [tex]h = 48[/tex], the time taken by the golf ball to be 48 feet above the ground is:
[tex]64\cdot t - 16\cdot t^{2} = 48[/tex]
[tex]16\cdot t^{2}-64\cdot t +48 = 0[/tex]
By Quadratic Formula, we have the following roots:
[tex]t_{1} = 3[/tex], [tex]t_{1} = 1[/tex]
The golf ball will be 48 feet above ground 1 and 3 seconds after being hit.
∠X=5x+30
∘
\angle \mathrm{Y}=3\mathrm{x}+60^{\circ}∠Y=3x+60
∘
Corresponding angles on parallel lines cut by a transversal are equal
5x + 30 = 3x + 60
Subtract 3x from both sides
2x + 30 = 60
Subtract 30 from both sides
2x = 30
Divide both sides by 2
X = 15
Find the area of this triangle
Use Heron's formula.
A = sqrt{(s - a)*s - b)(s - c)}, where a, b, and c represent the sides of the triangle.
We need to find s first.
So, s = (a + b + c)/2.
s = (13 + 6 + 9)/2
s = 28/2
s = 14
We now plug everything into the Heron's area formula.
A = sqrt{(14 - 13)(14 - 9)(14 -6)}
A = sqrt{(1)(5)(8)}
A = sqrt{40}
A = 6.3245553203
Let us now round to one decimal place as instructed. We round to the tenths place, in other words.
A = 6.3 cm^2

x ^ 2 - 2x = - 26
Answer:
Step-by-step explanation:
x²-2x=-26
add both sides (-2/2)² or 1
x²-2x+1=-26+1
x²-2x+1=-25
(x-1)²=25×-1
(x-1)²=5²×i²=(5i)²
x-1=±5i
x=1±5i

Answer:
x = 63.43...
Step-by-step explanation:
Ok, so the angle x is the same measure as the bottom right angle of the triangle because the bottom of the triangle and the dashed line are parallel. Knowing this we can simply solve for the bottom right angle and it will be the same as angle x.
To do this we can set up and equation with tangent because we are working with the opposite and adjacent sides of the triangle.
[tex]Tan(x) = \frac{opposite}{adjacent} = \frac{50}{25} = 2[/tex]
[tex]Tan(x)=2\\[/tex]
Now to isolate the variable, we can simply use the cotangent or inverse tangent.
[tex]Tan^{-1}(Tan(x)) = Tan^{-1}(2)\\x = Tan^{-1}(2)\\x = 63.43...[/tex]

2x - 5 < 33 what are all the values to this inequality
Answer:
x < 19
Step-by-step explanation:
Given that,
An inequality 2x - 5 < 33.
LHS of the inequality is 2x - 5
RHS of the inequality is 33
LHS < RHS
i.e.
2x - 5 < 33
Add 5 to both sides of the inequality
2x - 5 +5 < 33+5
2x < 38
Divide both sides by 2.
x < 19
So, the value of x is less than 19.
