Answer:

50.3

Step-by-step explanation:

Volume = pi * h * r^2   *** Diameter = 2 * radius

<em>Substitute</em>

Volume = pi * 4 * (4/2)^2

<em>Simplify</em>

Volume = pi * 4 * 4

<em>Simplify</em>

Volume = 16 pi, which is approx. 50.3

Which of the following is not equal to the other values? cos31.7° cos211.7° cos328.3° cos(-391.7°)
luda_lava [24]

Answer:

* cos 211.7 not equal the other values

Step-by-step explanation:

* Lets revise the angles in the four quadrant

- If the angle in the first quadrant is Ф, then the equivalent angles to

 it in the other three quadrant are

# 180° - Ф ⇒ 2nd quadrant (sin only +ve)

# 180° + Ф ⇒ 3rd quadrant (tan only +ve)

# 360° - Ф ⇒ 4th quadrant (cos only +ve)

# -Ф ⇒ 4th quadrant (cos only +ve)

# -180 + Ф ⇒ 3rd quadrant (tan only +ve)

# -180 - Ф ⇒ 2nd quadrant (sin only +ve)

# -360 + Ф ⇒ 1st quadrant (all are +ve)

* Lets solve the problem

∵ Ф = 31.7°

∵ cos 31.7 = +ve value

∵ 180° + Ф° = 180° + 31.7° = 211.7°

∵ cos (180° + Ф°) = - cos Ф° ⇒ cos (180° + Ф°) in the 3rd quadrant is

  same value as cos Ф but with -ve sign

∴ cos 211.7° = - cos 31.7°

∴ cos 31.7° ≠ cos 211.7°

∵ 360° - Ф° = 360° - 31.7° = 328.3°

∵ cos (360° - Ф°) = cos Ф° ⇒ cos (360° - Ф°) in the 4th quadrant has the

  same value and sign with cos Ф°

∴ cos 328.3° = cos 31.7°

∴ cos 31.7° = cos 328.3°

∵ -391.7° + 360° = -31.7° ⇒ more then clockwise turn by 31.7°

∵ cos (-Ф°) = cos Ф° ⇒ cos (-Ф°) in the 4th quadrant has the same value

  and sign with cos Ф°

∴ cos (-31.7°) = cos 31.7°

∴ cos 31.7° = cos (-390.7°)

* cos 211.7 not equal the other values

A line has a slope of 1/4.What is a slope parallel to it?What slope is perpendicular?
Pepsi [2]
A slope parallel to it will have the same slope. So it will be 1/4.

A perpendicular slope will have the opposite reciprocal of the given slope. So it will be -4.

Answer:

Step-by-step example explanation:

DOMAIN:

{

x

∣

x

≠

3

2

}

RANGE:

{

y

∣

y

≠

3

2

}

Explanation:

The domain consists of all numbers you can legally plug into the original. The excluded "illegal" values would be dividing by zero or negatives under square roots.

This expression has a denominator, so there is a risk of illegally dividing by zero. This would happen only if

2

x

−

3

=

0

2

x

=

3

x

=

3

2

This means that

x

=

3

/

2

is excluded from the domain. Therefore,

Domain: All real numbers except

x

=

3

/

2

. More formally, you could state the domain as

{

x

∣

x

≠

3

2

}

.

For rational functions, you find the range by evaluating the degree of the numerator compared to the degree of the denominator. If the degree of the top > degree of bottoms, then you have a horizontal asymptote at

y

=

0

. If they are equal, you have a horizontal asymptote. The coefficient of highest degree in the numerator is divided by the coefficient of the highest degree on the bottom. The result is

y

=

that fraction. So in our case, you have a horizontal asymptote at

y

=

3
