Well you can report me but I think it should be halved to get the answer if trapezoid is also a 3d figure and the number 1,500 should be divided by 2,

1,500 divided by 2=750 . so maybe the volume for A=750 oh and rounded to the nearest 10 is 760

Mrrafil [7]

Answer:

<h3><em>π/4 and 3π/4</em></h3>

Step-by-step explanation:

Given the equation 2\sin^2(x) = 1 \\, we are to find all the values of x in the interval  [0, 2π] that satisfies the equation.

Simplifying the equation:

2\sin^2(x) = 1 \\\\sin^2x = \frac{1}{2} \\\\

Square both sides of the equation;

\sqrt{sin^2x } = \sqrt{\frac{1}{2} } \\\\sin(x) = \sqrt{0.5}\\ \\sin(x) = 0.7071\\\\x = sin^{-1}0.7071\\\\x \approx 45^0

The general formula for sin(x)  is x = nπ + (-1)ⁿ∝ where n = 0, 1, 2, 3...

Since ∝ = 45° = π/4.

x = nπ + (-1)ⁿπ/4

when n = 1

x = π + (-1)¹π/4

x =  π - π/4

x = 3π/4

<em>Hence the values of x within the given interval are π/4 and 3π/4</em>

mina [271]

Answer:

B. 62.5 m

Step-by-step explanation:

∠EDF and ∠ADC are vertical angles, and therefore equal.

EF and AC are parallel, so ∠DEF and ∠DAC are alternate interior angles, as well as ∠DFE and ∠DCA.  Therefore, each pair is equal.

From this, we can say ΔDEF and ΔDAC are similar triangles.  So we can write a proportion:

10 / 20 = DB / 125

DB = 62.5
