Answer:
y= (-7/9)(x-1)
Step-by-step explanation:
finding the slope:
slope= rise/run
rise= 7-0=7
run= -8-1= -9
slope= -7/9
point slope form:
y= (-7/9)(x-1)
Answer:
20% of 240 is 48
Step-by-step explanation:
48 times 5 equals 240
20% times 5 equals 100%
100% = 240 text messages
From the law of sines, we have
![l = h\sin(\theta) = h\cos(\alpha)](https://tex.z-dn.net/?f=%20l%20%3D%20h%5Csin%28%5Ctheta%29%20%3D%20h%5Ccos%28%5Calpha%29)
where
is the leg we're interested in,
is the hypothenuse,
is the angle opposite to
, and
is the angle between
and
.
So, in the first case, we can use
![x = 15\sin(35) \approx 8.6](https://tex.z-dn.net/?f=%20x%20%3D%2015%5Csin%2835%29%20%5Capprox%208.6%20)
And in the second excercise, we use
![x = 11\cos(44) \approx 7.6](https://tex.z-dn.net/?f=%20x%20%3D%2011%5Ccos%2844%29%20%5Capprox%207.6%20)
Answer:
4.5
Step-by-step explanation:
Use the distance formula to get sqrt(2^2+4^2) or sqrt20, which is 2sqrt5. sqrt5 is approximately 2.236, so 2*2.236 is 4.472 or 4.5.
