First step is 5+7(36x+8y) because you have to distribute
Using the Law of Cosines:
d= √(840^2 + 800^2 - 2*840*800*cos(105))
d = √1693452.796
d = 1301 miles.
The answer is B.
Answer: D
Step-by-step explanation:be cause you have to add 4 to negetive 5 and and that negetive 1 which is greater than -5
Answer:
height AB is 8 cm
Step-by-step explanation:
AB= √AC^2- BC^2
= √(10)^2- (6)^2
= √100-36
= √64
= 8
We want to find one-half of the reciprocal of 7/sqrt(98). Let's write down an expression for this:

We can rewrite 98 into 


The square root of 49 is 7
