A sphere with a radius of 4.217 cm (true or false)

A sphere with a diameter of 4.217 cm (true or false)

A cone with a radius of 10 cm and a height of 3 cm(true or false)

A cylinder with a radius of 1 cm and a height of 10 cm(true or false)

A cylinder with a radius of 4.47 cm and a height of 5 cm(true or false)

Answer:

(1 cm)cos3πt

Step-by-step explanation:

Since the piston starts at its maximal height and returns to its maximal height three times evert 2 seconds, it is modelled by a cosine functions, since a cosine function starts at its maximum point. So, its height h = Acos2πft

where A = amplitude of the oscillation and f = frequency of oscillation and t = time of propagation of oscillation.

Now, since the piston rises in such a way that it returns to the maximal height three times every two seconds, its frequency, f = number of oscillations/time taken for oscillation where number of oscillations = 3 and time taken for oscillations  = 2 s

So, f = 3/2 s =1.5 /s = 1.5 Hz

Also, since the the piston moves between 3 cm and 5 cm, the distance between its maximum displacement(crest) of 5 cm and minimum displacement(trough) of 3 cm is H = 5 cm - 3 cm = 2 cm. So its amplitude, A = H/2 = 2 cm/2 = 1 cm

h = Acos2πft

= (1 cm)cos2π(1.5Hz)t

= (1 cm)cos3πt

Answer:

The circumference of the tires is of 94.25 inches.

Step-by-step explanation:

Circumference of a circle:

The circumference of a circle, with radius measuring r, is given by:

[tex]C = 2\pi r[/tex]

In which the radius is half the diameter.

In this question:

Diameter of 30 inches, so the radius is 30/2 = 15 inches.

The circumference is:

[tex]C = 2\pi (15) = 30\pi = 94.25[/tex]

The circumference of the tires is of 94.25 inches.

Answer:

Value of x = -7

Step-by-step explanation:

Given:

First angle = 83°

Second angle = 24°

Third angle = (38 - 5x)°

Find:

Value of x

Computation:

We know that sum of all interior angle in triangle is 180°

So,

83 + 24 + 38 - 5x = 180

145 - 5x = 180

-5x = 35

x =  -7

Value of x = -7

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] ) point - slope form of a line.

y = mx + b slope- intercept form of a line.

~~~~~~~~~~~~~~~~~

( - 2, - 7 )

( 0, - 4 )

m = [tex]\frac{- 4 - (-7)}{0 - (- 2)}[/tex] = [tex]\frac{3}{2}[/tex]

y - ( - 4 ) = [tex]\frac{3}{2}[/tex] ( x - 0 )

y + 4 = [tex]\frac{3}{2}[/tex] x

y = [tex]\frac{3}{2}[/tex] x - 4 slope- intercept form

3x - 2y = 8 standard form

I think it is 6 because 10 is half of 20 so 6 is half of 12

Sam should wear green shirt for 6 days in next 12 days.

Fraction is a number that represent part of a whole quantity. It has two parts, numerator and denominator, the number above the horizontal line is numerator, and number under the the line is denominator.

Given,

Sam wore green shirt on 10 of the last 20 days

Fraction of days the wearing green shirt to total days = 10/20 = 1/2

Number of days of wearing green shirt in next 12 days

= 12 × 1/2

= 6 days

Hence, in next 12 days, Sam should wear green shirt for 6 days.

Answer:

x = 33

Step-by-step explanation:

cross-multiply:

x-9 = 2(12)

x-9 = 24

x = 33

Answer:

The answer is 33.

Step-by-step explanation:

1) Multiply both sides by 2.

[tex]x - 9 = 12 \times 2[/tex]

2) Simplify 12 × 2 to 24.

[tex]x - 9 = 24[/tex]

3) Add 9 to both sides.

[tex]x = 24 + 9[/tex]

4) Simplify 24 + 9 to 33.

[tex]x = 33[/tex]

Hence, the answer is 33.
