Answer:
1: a
2: a
3: a
4: b
Step-by-step explanation:
a right triangle means the pythagorean theorem applies
a^2 + b^2 = c^2
is true for the triange
a and b are the two shorter sides and c is the long side
test with values to see if true
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
true, it is a right triangle
3 root^2 + 8 root^2 = 11 root^2
3 + 8 = 11
11=11
true, it is a right triangle
3^2+ 10 root^2 = 19 root^2
9 + 10 = 19
19=19
true, it is a right triangle
3^2 + 5^2 = 6^2
9+25= 36
34= 36
false not a right triangle
i hope this helps
Answer:
Z=+6
Step-by-step explanation:
Z^5=-7776i
Let's note that i I mathematics means negative one i.e
i = -1
So the equation is equal to
Z^5=-*-(7776)
Z^5 = 7776
Z= 5√7776
Since it's a divisible by 6
It's giving us a clue that 6 it's the answer.
Ok let's check the 5th root of 7776 in our calculator.
Z=+6
+6 is the solution to the equation
Z^5=-7776i
Sue has saved $54 more than Bill
Step-by-step explanation:
Given
Sue saves $5 a week. so after 36 weeks he will have
= 36 * 5
= $180
Bill's saving is modeled by
m = 3.5w where w is the number of weeks
After 36 weeks,
The difference between savings of Bill and Sue
Hence,
Sue has saved $54 more than Bill
