Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h
X*94 +688*6 = 267*100
94x+4128=26700
94X=22572 /94
X=240.128
C is the closest answer
Answer:
b=8
Step-by-step explanation:
7b-7-8b=-15
Combine like terms
-b-7=-15
Add 7 on both sides
-b=-15+7
-b=-8
Divide by -1
b = 8
Answer:
so your answer would be 60$
Step-by-step explanation:
I = P * r * t
Here, P = $600
r = 0.05 (decimal value for 5%)
t = 2 years
Part a)
The interest earned will be:
I = P * r * t
I = 600 * 0.05 * 2
I = $60
Part b)
The balance in the account will be $600 plus the interest earned or:
$600 + 60 = $660
Answer:
y=a(x-p)(x-q)
y=a(x+2+√2)(x+2-√2)
passing through point (-1,1)
substitute
1=a(-1+2+√2)(-1+2-√2)
1=a(1+√2)(1-√2)
1=a(1-2)
1=a(-1)
a=1/(-1)
a=-1
y=-(x+[2+√2])(x+[2-√2])
y=-(x2+4x+2)
