Answer: True.

Step-by-step explanation:

In geometry , we have three undefined terms as :

1) point [ no dimension]

2) line [ one dimension]

3) plane [ two dimension]

A point is just a tiny mark on Cartesian plane which has no length like a line , no width and area like a plane or no volume like a three dimensional shape . We can use only its location but cannot measure it.

Hence, it has no dimension.

Hence, the given statement "a point occupies zero dimensions" is a true statement.

Which of the following ratios is not equivalent to the other three 2/3 4 to 6 4/5 8 to 12

lara [203]

Answer:

4/5

Step-by-step explanation:

Because 2/3 is the same as 4/6 and 8/12.

Multiply 2/3 by two and you get 4/6 (4/6 is just the unsimplifyed ratio and so is 8/12)

Leaving 4/5 as the odd one out

Express your answer exactly

Inessa [10]

Answer:

sin(θ) = $\frac{3\sqrt{13} }{11}$

Step-by-step explanation:

See the attachment.

We know that cosine is adjacent divided by hypotenuse. So since cos(θ) = -2/11, then the adjacent is -2 and the hypotenuse is 11.

Sine is opposite divided by hypotenuse. Find the opposite, which is the unlabelled side, by using the Pythagorean Theorem:

x = $\sqrt{11^2-(-2)^2} =\sqrt{121-4} =\sqrt{117} =3\sqrt{13}$

So, sin(θ) = $\frac{3\sqrt{13} }{11}$

Hope this helps!

A horse walks around a circular track while its trainer stands in the center. The trainer is 14 feet from the horse at all times

max2010maxim [7]

The horse traveled 439.6 feet after walking around the track 5 times

Solution:

Given that, horse walks around a circular track while its trainer stands in the center

The trainer is 14 feet from the horse at all times

Therefore, radius of circular track = 14 feet

The circumference of circle is the distance traveled by horse for 1 lap

The circumference of circle is given as:

$C = 2 \pi r$

Where, "r" is the radius and $\pi$ is a constant equal to 3.14

$C = 2 \times 3.14 \times 14\\\\C = 87.92$

Thus the distance traveled by horse for one time in circular track is 87.92 feet

About how far had the horse traveled after walking around the track 5 times?

Multiply the circumference by 5

$distance = 5 \times 87.92\\\\distance = 439.6$

Thus the horse traveled 439.6 feet after walking around the track 5 times

5-t3 when t=12 what's the answer ?

Fantom [35]

Answer:

-1723

Step-by-step explanation:

Evaluate 5 - t^3 where t = 12:

5 - t^3 = 5 - 12^3

12^3 = 12×12^2:

5 - 12×12^2
