Answer:
63 ft^2
Step-by-step explanation:
We know that the area for the rectangle is 72 feet squared.
We also know that the area for the triangle is 9 feet squared.
To find out the area of the whole thing you subtract 72-9 whcih gives you 63.
Answer:
Step-by-step explanation:
a=30
b= 17
c= 18
we actually already found angles B and C for the last problem I think we said 30 and 32 so we would be able to guess that angle A is about 118° but.. let's do the math... and see
angle A = arcCos[ b^2 + c^2 - a^2 / 2*b* c ]
A = arcCos[ 289 +324 - 900 / 2*17*18]
A = arcCos[ -287 / 612 ]
A = arcCos[ -0.468954 ]
A = 117.9664 °
ohh and we're off by 0.0336 phooy :P soo far off... :P
rounding to nearest 10th
A = 118.0 ° ( ohh right on the money :P) yay, I feel better. :P
(a) Fermat's little theorem states that for any prime , we have
for any integer . Then
so 7 does indeed divide 999,999.
(b) Generalizing, we have
for positive integer . Now, since 1 = 1001 - 1000 and , it follows that is its own inverse modulo 1001, i.e.
This means
which is what we wanted to show.
