Which of the following represents a geometric sequence?

grin007 [14]

Answer:

Option 1 is a geometric sequence.

I 1/4, 1/4, 1/4, 1/4

II 1/4, 1/5, 1/6

III 1/4, 1, -4, 1/6

IV 1/4, -4, 1/4, -4

For any geometric sequence there should be a common ratio

To find common ratio we divide consecutive terms

lets check option I

I 1/4, 1/4, 1/4, 1/4

When we divide 1/4 by 1/4 we will get 1

Same 1 for other two terms, so common ratio is 1

Hence the first option is a geometric sequence

The total weight of 30 bags of flour and 4 bags of sugar is 42.6 kg. if each bag of sugar weighs 0.75 kg, what is the weight of

slavikrds [6]

X = weight of each bag of flour

30x + 4*0.75 = 42.6
30x + 3 = 42.6
30x = 39.6
x = 39.6/30
x = 1.32kg

A circle has a circumference of 20π cm. What is the measure(in degrees) of an arc length of 4π cm?

Alexeev081 [22]

Answer:

The degree measure of the requested angle is $72^o$

Step-by-step explanation:

Recall that the formula for the arc length (S) is given by:

$s=R\,*\theta$

where R is the circle's radius and the angle $\theta$ (which is the angle subtended by the arc "S") must be given in radians.

So first, we need to find the radius of the circle, given the information on its circumference ( $20\,\pi \,$ cm).

Since the circumference of a circle is given by: $2\,\pi\,R$ ,

then we can find what the radius is in our case:

$2\,\pi\,R = 20\,\pi\,\,cm\\R=\frac{20\,\pi}{2\,\pi} \,cm\\R=10\,\,cm$

Now, with the radius (10 cm) we can use the arc length formula to find the subtended angle $\theta$ in radians:

$s=R\,*\theta\\4\,\pi\,\,cm=(10\,\,cm)\,\theta\\\theta=\frac{4\,\pi}{10} \\\theta=\frac{2}{5} \,\pi$

Now we find the degree equivalent to this angle, via multiplying it by $\frac{180^o}{\pi}$ , which renders:

$\frac{2}{5} \pi\,(\frac{180^o}{\pi} )=72^o$

So this is the degree measure of the requested angle.
