Answer:
so i'm assuming you'd use Pythagoras:
so 15^2-12^2=81
square root it=9 which is I
to find T we do 41^2-9^2=1600
square root that is 40 so T=40
Answer:
(If you were asking for the answer for question 7)
c. Initially, Cassie has $20 in her account.
Step-by-step explanation:
-20 represents the slope or rate of change of the line and 275 represents the y-intercept or starting point of the line on the y-axis. C is the right answer because initially Cassie had $275 in her account, not $20.
Wouldnt that be zero cuz they used more then they started of with?
X^2+14x-176=0
(x+22)(x-8)
x=-22,8
This is because the 2 numbers in the factorisation must have multiple of 176& and a sum of 14
Answer:
z= 69
Step-by-step explanation:
79+122+90+z=360 angle sum property
360-291=69
so z=69 degree
