The prime factors of a number are 2, 2, 2, and 5. What is the number?
fgiga [73]

Answer: 40

Step-by-step explanation:

Since 40 could be = 1 x 40, 2 x 20, 4 x 10, or 5 x 8.

The Factors of 40 will therefore be: 1, 2, 4, 5, 8, 10, 20, 40.

The Prime factor then is: 2, 2, 2, 5

Multiplying them together gives 40.

Answer:

81.75 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = \frac{1}{2} h (a + b)

where a, b are the parallel bases and h is the perpendicular height

Calculate h using the right triangle and the sine ratio

sin30° = \frac{opposite }{hypotenuse} = \frac{h}{10}

Multiply both sides by 10

10 × sin30° = h, thus

h = 5

a = 12 and b = 8.7 + 12 = 20.7, hence

A = \frac{1}{2} × 5 × (12 + 20.7)

   = 0.5 × 5 ×32.7

   = 81.75 ft²

In this exercise, consider a particle moving on a circular path of radius b described by r(t) = b cos(ωt)i + b sin(ωt)j, where ω
Bingel [31]

Answer:

Acceleration of the particle = bw^{2}

Step-by-step explanation:

We are given the position vector of a particle moving in a circle of radius b units.

r(t) = b cos(ωt)i + b sin(ωt)j

Velocity , v =\frac{dr}{dt} = -bω sin(ωt)i + bω cos(ωt)j

The magnitude of velocity, v =\sqrt{v_x^{2} +v_y^{2} }

Squaring both sides,

v^{2} = b^{2} w^{2}(sin^{2}(wt)+cos^{2}(wt))

Since sin^{2}(wt)+cos^{2}(wt)) = 1

v^{2} = b^{2}w^{2}

The acceleration towards the centre is called the centripetal acceleration and is given by

a = \frac{v^{2} }{r}

a = \frac{b^{2}w^{2}}{b}

a = bw^{2}
