Hey do you need to show your work for these? I found an answer key
Step-by-step explanation:
We need to use law of cosines
c²=a²+b²-2abcos(C)
let x= angle xzy
plugging in what we have the equation looks like
17²=22²+20²-2*22*20*cos(x)
289=484+400-880cos(x)
.676136364=cos(x)
x=47.45754235
b.)
The smallest angle should be opposite to the smallest side
Using the law of cosines again we get
9²=13²+17²-2*13*17*cos(x)
81=458-442cos(x)
.852941176=cos(x)
x=31.46697634
Store 1: $26.62/36=0.74 per oz.
Store 2: $22.42/28=0.80 per oz
So store 1 is .06 cents cheaper than store 2
Answer:
The correct answer is -8 and 7
Hope you have a wonderfull day :)
<span> lets say integrand is e^(y/x):
∫(x = 0 to 1) ∫(y
= 0 to x^2) e^(y/x) dy dx
= ∫(x = 0 to 1) xe^(y/x)
= ∫(x = 0 to 1) x(e^x - 1) dx
= ∫(x = 0 to 1) (xe^x - x) dx
= (xe^x - e^x) - (1/2)x^2
= 1/2. </span>
M=4b
m=27+b
subsitute
4b=27+b
minus b
3b=27
divide 3
b=9
sub back
4b=m
4(9)=m
36=m
michel=36 and brandon is 9
