Please please please help

sattari [20]

Answer:

Part A: It would be a rectangle because the top face is a triangle and since the cut is parallel it would be the same shape.

Part B: It would be a rectangle because the faces that are perpendicular to the base of the rectangle are rectangles so the cut would be the same shape.

Note: The perpendicular sides look like squares, but you do not want to assume that they are squares unless it is stated.

Find function domain f(x) = sqrt( 2sin x - 1 )

vekshin1

Answer:

{x ∈ ℝ : x ≥ π/6 +2πn and x ≤ π/6 + 2πn and n ∈ ℤ}

Step-by-step explanation:

sinx can run from -1 to +1

2sinx can run from -2 to +2

2sinx -1 can run from -3 to +1

However, the square root is imaginary when x < 0. So, the condition is

2sinx -1 ≥ 0

2sinx ≥ 1

sinx ≥ ½

x ≥ π/6 (30°)

So, in the interval [0, 2π], π/6 ≤ x ≤ 5π/6

However, the sine is a cyclic function and repeats itself every 2π.

Over all real numbers, the condition is (π/6 +2πn) ≤ x ≤ (5π/6 + 2πn).

The domain is then

{x ∈ ℝ : x ≥ π/6 +2πn and x ≤ π/6 + 2πn and n ∈ ℤ}

Please help me, I dont know this :double s, then subtract t from the result

lesantik [10]

Basically just convert this into an equation:
Let’s use “x” as the result
“•” is the multiplication symbol

Double s: s•2
Subtract t from result: =x-2

So, s•2=x-2

A blimp is flying at a speed of 40mph and going in a direction of 80 degrees. After 3 hours of flying it turns and travels 1 hou

kykrilka [37]

Bearing is a topic that can be used to locate the position of an object at a given time. Therefore, the blimp is 80 m far away from its starting point. And in the North-East direction.

The speed of an object relates the distance it covers to the time taken to cover the said distance.

i.e speed = $\frac{distance}{time taken}$
