we have
we know that
so
two solutions
<u>first solution </u>
the first solution is the interval---------> (-1,∞)
<u>second solution</u>
the second solution is the interval---------> (-∞,-1)
therefore
the solution is all real numbers except the number 
the answer in the attached figure
Answer:
73.74°
Step-by-step explanation:
sin Ф = opposite/hypotenuse
sin Ф = 24/25
(24/25) = 73.74
Answer:
First find the inner angle:
[ given hypotenuse = 500 ft ]
using sine rule:
using pythagoras theorem:
Answer:
0
Step-by-step explanation:
If the line goes straight it has no slope
In this case you equation should be just
X=2
Not sure if you can do this but it sounds like a velocity/time/distance equation.
d=vt
v=d/t
t=d/v
70 w/m = t
15 pages - 350 w/p
She can type 70 words per minute (w/m). There are 350 words per page (w/p). She needs 15 pages. So first you have to find how many words she can type in one hour. 60 minutes in an hour, she can type 70 w/p.
60x70=4,200 words per hour (w/h).
Next you should find out how many words on 15 pages total.
350x15= 5,250.
I would put 4,200/5,250 as a fraction to gage how much she has left. She has most of it done already in ONE HOUR. Reduced, she has done 4/5s of the essay. Now you just need to get 1/5 of 5250, which is 1050.
She needs to do 1050 words. If one minute is 70, do 1050/70 which is 15.
The answer is 1 hour and 15 minutes.
I think... ;)
