Answer:

2.1 s

Step-by-step explanation:

1. Write the equation

The formula for vertical displacement is

y =  h + v₀t - ½gt²

h = 50     ft

v₀ = 10     ft/s

g = 32.2 ft/s²

Insert the values

y = 50 + 10t - ½ × 32.2t²

y = 50 + 10t - 16.1t²

The graph below shows the height as a function of time.

2. Solve the equation

a = -16.1; b = 10; c = 50

[tex]\begin{array}{rcl}x & = & \dfrac{-b\pm\sqrt{b^2 - 4ac}}{2a}\\\\& = & \dfrac{-10\pm\sqrt{10^2-4(-16.1) \times 50}}{2(-16.1)}\\\\& = & \dfrac{-10\pm\sqrt{100 - (-3220)}}{-32.2}\\\\& = & \dfrac{-10\pm\sqrt{100 + 3220}}{-32.2}\\\\& = & \dfrac{-10\pm\sqrt{3300}}{-32.2}\\\\& = & \dfrac{-10\pm 57.62}{-32.2}\\\\\end{array}[/tex]

[tex]\begin{array}{rcl}x = \dfrac{-10 + 57.62}{-32.2}& \qquad & x = \dfrac{-10 -57.62}{-32.2}\\\\x = \dfrac{47.62}{-32.2}& \qquad & x = \dfrac{-67.62}{-32.2}\\\\x = -1.479& \qquad & x =\textbf{ 2.1 s}\\\\\end{array}\\\text{It takes the stunt double $\large \boxed{\textbf{2.1 s}}$ to reach the ground.}[/tex]

Answer:

y = -1/3x - 11/3

Step-by-step explanation:

line a: y = -1/3x - 5

3 = -1/3(2) - b

3 = -2/3 - b

3 + 2/3 = b

3/1 + 2/3 = b

9/3 + 2/3 = b

11/3 = b

The answer is 10√2

The airplane's path is an illustration of right-triangles

Represent the angle of descent with [tex]\theta[/tex]

The angle of descent, [tex]\theta[/tex] is then calculated using the following tangent identity

[tex]\tan(\theta) = \frac{35000\ feet}{150 \ miles}[/tex]

Convert feet to miles

[tex]\tan(\theta) = \frac{6.6287879\ miles }{150 \ miles}[/tex]

Divide

[tex]\tan(\theta) = 0.0442[/tex]

Take the arc tan of both sides

[tex]\theta = \tan^{-1}(0.0442)[/tex]

Evaluate the arc tan

[tex]\theta = 2.5[/tex]

Hence, the angle of descent is 2.5 degrees

Represent the plane's path with p

The plane's path is calculated using the following Pythagoras theorem

[tex]p^2 = (150\ miles)^2 + (35000\ feet)^2[/tex]

Convert feet to miles

[tex]p^2 = (150\ miles)^2 + (6.6287879\ miles)^2[/tex]

Evaluate

[tex]p^2 = 22543.940829[/tex]

Take the square roots

[tex]p = 150.15[/tex]

Hence, the plane's path is 150.15 miles

Answer:

The answer would be 116

Step-by-step explanation:

The angles X and Z would be equal at 32 so multiply them by 2 and you would get 64 subtract 64 from 180 and you would get 116

Answer:

Y =116

Step-by-step explanation:

We know that angle Z = angle X since they are base angles  and  the sides are the same length

The sum of the angles of a triangle are 180

X+Y+Z = 180

32+ Y + 32 = 180

64+Y=180

Y = 180-64

Y =116

g = 9y

this is true because khan academy

The missing factor of the given equation is 9y.

The factors of the expressions are the simplified expression which when multiplied results in the original expression.

Divide 18y³ by 2y² to determine the missing factor.

G=18y³/2y²

Express the numerator and denominator in the factored form and simplify.

G=(2·3·3·y·y·y)/(2·y·y)

G=3·3·y

G=9y

So, the missing factor of the given equation is 9y.

Answer:

Debit Salaries Expense $480 and credit Salaries Payable $480

Step-by-step explanation:

Firstly, we will need to calculate the salary expense of the company on these two employees.

Mathematically, that would be

2 employees * 2 days * 120/employee/day = 2 * 2 * 120 = $480

Thus, the month-end adjusting entry to record the salaries earned but unpaid is that salaries expense will be debited $480 and salaries payable will be credited $480

Answer:

None

Step-by-step explanation:

In this case we must pass everything to the same unit of measure, we know that the total is 5 liters of soft drink and that each plastic cup has a capacity of 250 cubic meters.

We know that 1 liter is equivalent to 0.001 cubic meters, therefore we will pass the cubic meters of the plastic cup to liters, like this:

250 m ^ 3 * 1 L / 0.001 m ^ 3 = 250,000 L

Therefore we realize that the glass has a very large capacity, which suggests that there is an error in the statement, maybe it is not a cubic meter but a cubic centimeter, but as it is, it cannot serve any plastic cup because the capacity of this cup is very large with respect to the total amount of soft drink.
