Answer:

C≈90

Step-by-step explanation:

remember circumference formula

\displaystyle C =  2\pi r

given that,r=15 thus substitute:

\displaystyle C =  2\pi .15

simplify mutilation:

\displaystyle C =  30\pi

substitute the given value of π:

\displaystyle C =  30.3

simplify multiplication:

\displaystyle C = 90

and we are done!

Is 1.5 miles greater than 2500 yards
worty [1.4K]
Hey there!

According to our customary units of miles, 1 mile is equal to 5,280 feet - and 3 feet is a yard. That means, we have to divide 5,280 by 3 to figure out how many yards are in a mile:

5280/3 = 1760

That means that one mile is 1760 yards. But we're not finished yet. It says 1/5 miles, not one mile. Therefore, we take one half of the total distance in yards of a mile and add it to that 1760, because it's 1.5, or 1-and-a-half. Which, in technical terms means "1-plus-a-half".

We have:

1760 + 1760/2 = 1760 + 880 = 2640

Therefore, 1/5 miles, since it's 2640 yards, is greater than the 2500 yards specified in the question.

Hope this helps!

Answer:

0.0017

Step-by-step explanation:

A percent is part of 100%. It converts to a decimal by moving the decimal point two place values to the left.

For example, 60%=0.60

For 0.17% = 0.0017

Find all unit vectors that are parallel to the line tangent to the curve y = 2 sin x at the point (π/6, 1). (b) Find the unit ve
liberstina [14]

Answer:

For (a) ±< cos ( π /6) , sin( π /6 ) > = ± < 1 /2 , √ 3 /2 > For (b)=   < √ 3 /2 ,- 1 /2 > For (c) see attachment.

Step-by-step explanation:

y'atx=π/6 is 2cos(π/6)=√3.

This direction θ=ψ is given by tanψ=√3.

Inversely, ψ=tan−1√3 is π/6. For the opposite direction ,

it is π+π/6.

The unit vector in the direction θ=π/6 is

<cos(π/6),sin(π/6)>.

For the opposite direction, it is

<cos(π+π/6),sin(π+π/6)>

=<−cos(π/6),−sin(π/6)> .

For Part (b)

That is, the slope of the tangent line is √3. So

(1,√3)

gives the direction of the line and

(√3,−1)

gives the direction of the perpendicular line.

(Note that (b,−a)⊥(a,b) for any vector.)

For Part C
