2 x pi radians = 360 degrees, [remember this formula]
2 x 3.14 = 6.28 radians = 360 degrees
therefore 1 radian = 360 degree/ 6.28 or 57.32 degrees approx.
3.5 radians is therefore = 57.32 x 3.5 = 200.62

closest answer would be b ) 200.54 degrees

The distance traveled (d) varies directly as the time (t) of
Helen [10]

Answer:

2.70 hours to travel 180 mi.

Step-by-step explanation:

The distance traveled (d) varies directly as the time (t) of travel, by the following formula:

s = \frac{d}{t}

In which s is the velocity.

It takes 63 min to travel 70 mi.

So i am going to find the velocity in miles per minute

s = \frac{70}{63} = 1.11

how many hours would it take to travel 180 mi?

I am first going to find the time in minutes, then divide by 60 to pass to hours.

s = \frac{d}{t}

st = d

t = \frac{d}{s}

t = \frac{180}{1.11}

t = 162.16

It takes 162.16 minutes = 162.16/60 = 2.70 hours to travel 180 mi.

Two students use different methods to solve this multiplication problem: 1/2 • -4 4/5
sesenic [268]

Solution:

\frac{1}{2}\times-4 \frac{4}{5}

As one of the fraction is a proper fraction and another one is Mixed fraction.

There are two methods of solving it.

1. \frac{1}{2}\times-4 \frac{4}{5}=\frac{1}{2} \times \frac{-24}{5}=\frac{-12}{5}=-2\frac{2}{5}

2. \frac{1}{2}\times-4 \frac{4}{5}=\frac{1}{2}[-4-\frac{4}{5}]=\frac{1}{2}\times (-4)+\frac{1}{2}\times\frac{-4}{5}=-2+\frac{-2}{5}=\frac{-10-2}{5}=\frac{-12}{5}=-2\frac{2}{5}→→Here i have used Distributive property with respect to addition and Subtraction i.e a×(b+c)= a ×b + a×c or a×(b-c)=a×b-a×c

Now, you can fill the blanks by yourself.

How is this written in an expanded version?
Yuri [45]

Powers distribute over multiplications:

(ab)^c = a^c\cdot b^c

So, you have

(3k^5)^2 = 3^2 \cdot (k^5)^2

Now, 3^2 is simply 9.

As for (k^5)^2, we have to use the rule

(a^b)^c = a^{bc}

to get

(k^5)^2=k^{5\cdot 2}=k^{10}

So, the final answer is

(3k^5)^2 =9k^{10}

Help please ASAP 10 points
Reika [66]

Answer:

The answer is D

Step-by-step explanation:

Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary

This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.

You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other

Hope this helped you!!!

:)
