C. Most of the data was relatively close in value, but there must have been a few very small numbers in the data.

DIA [1.3K]

<u>c) 3, 6, 9 12</u> is NOT a geometric progression

<h3>Further explanation </h3>

Geometry sequences are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

$\large {\boxed {\bold x_n = ar ^ {n-1}}}$

where:

a is the first term, and

r is the common ratio

So we have to see the series has the same ratio or not

a. $\dfrac{5}{1}=\dfrac{25}{5}=5\to \rm geometric\:progression$

b. $\dfrac{8}{4}=\dfrac{16}{8}=2\to \rm geometric\:progression$

c. $\dfrac{6}{3}\neq \dfrac{9}{6}\to \rm not\:geometric\:progression$

d. $\dfrac{6}{2}=\dfrac{18}{6}=3\to \rm geometric\:progression$

A triangle has two constant sides of length 5 feet and 7 feet. The angle between these two sides is increasing at a rate of 0.9

o-na [289]

Answer: $12.74 ft^2/s$

Step-by-step explanation:

Given

Two sides of triangle of sides 5 ft and 7 ft

and angle between them is increasing at a rate of 0.9 radians per second

let $\theta$ is the angle between them thus

Area of triangle when two sides and angle between them is given

$A=\frac{ab\sin C}{2}$

$A=\frac{5\times 7\times \sin \theta }{2}$

Differentiate w.r.t time

$\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\cos theta }{2}\times \frac{\mathrm{d} \theta }{\mathrm{d} t}$

at $\theta =\frac{\pi }{5}$

$\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\times cos(\frac{\pi }{5})}{2}\times 0.9$

$\frac{\mathrm{d} A}{\mathrm{d} t}=12.74 ft^2/s$

the big wheel could have a 52 inch diameter and the small wheel could have an 18 inch diameter.What is the circumference of the

BlackZzzverrR [31]

Before we begin, let's cross out "the small wheel could have an 18 inch diameter". This is useless information and should be disregarded to avoid confusion. Lots of questions include extraneous information to make you second guess yourself, so it is important to be aware of what the question is asking you and what you need in order to answer it.

The formula for circumference is $\pi$ x diameter. With this formula, we can substitute the value of the diameter, 52, into the equation.

Circumference = 3.14 x 52
Circumference = 163.28

Final Answer: the circumference of the big wheel is 163.28 inches

Find the size of the marked angles

morpeh [17]

Answer:

b = 55°

c = 35°

Step-by-step explanation:

b° = 180° - (85°+40°) = 180° - 125° = 55°

c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
