D 0.8

sin^2(x)+cos^2(x)-1

if x=0.6

then 0.6^2+cos(x)=1

cos^2=1-0.36=0.64

cos(x)=±0.8

Fran works due north of home. Her husband Juan works due east. By the time Fran is 5 miles from home the distance between them i

lana66690 [7]

If I understood the question correctly, let's set the coordinates (5,5) from the origin (the home). To find the longer side of the triangle, (the distance between the husband and wife), we use A squared * B squared= C squared. 25*25=625, the square root of 625 is 25. So the distance between the husband and wife would be 25 miles. Therefore, one mile less than their distance would be 24 miles. To answer your question, Juan is 24 miles from home.

Please help me with geometry !! Been stuck a while

Nataly [62]

Answer:

area of circle having radius 3

is πr²=π*3²=9π square units

area of circle having radius 2

=πr²=π×2²=4π square units

again

area of big circle having radius [3+2]=5 units

=πr²=π×5²=25π square units

Now

area of shaded region=25π-4π-9π=12π or 37.7square units.

A fast typist can type 120 words in 100 seconds. At that rate, how many seconds would it take to type 258 words?

Alexeev081 [22]

Answer: 215 seconds

Step-by-step explanation:

This is a ratio problem so you can set up the ratio like this:

120 words : 100 second.

If you divide both sides of the ratio by 120 you get:

1 word: 0.8333 seconds

Multiply both sides of the ratio by 258 and you get:

258 words: 215 seconds.

Therefore typing 258 will take them 215 seconds.
