Answer:
9.22
Step-by-step explanation:
The distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the given coordinates, the distance between them is ...
d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22
The length of AB is about 9.22 units.
Answer:
13
Step-by-step explanation:
500 - 302=198
198 divided by 15 = 13. 2 round down to 13. 13 guests.
The 6 is in the ones place the 1 is in the tens place and the 2 is in the hundreds place.
Answer
A
Step-by-step explanation:
First, lets go through B-D and explain why they are correct.
B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.
C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.
D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.
A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.
Hope this helps!
Answer:
Step-by-step explanation:
Given
z=119+120 i
Let 
Squaring both sides
Comparing real and imaginary part
Re(LHS)=Re(RHS)
-----------1
comparing Im(LHS)=Im(RHS)
120=2pq
Substitute q in 1
Let 
we take only Positive value because 
x=149.85
thus 
thus
