Answer:
A 5.5% = 5400 B 5% = 1800
Step-by-step explanation:
A + B = 7200
A * 0.055 + B * 0.05 = $387
A = 7200 - B
(7200 - B)*0.055 + B*0.05 = 387
396 - 0.055B + 0.05B = 387
396 - 0.005B = 387
0.005B = 9
B = 1800
A = 7200 - B = 7200 - 1800
A = 5400
Hello from MrBillDoesMath!
Answer:
11
Discussion:
Solution by distance formula:
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt ( (-1 - (-1)
)^2 + (4 - (-7))^2 )
= sqrt ( ( -1 + 1) ^2 + (4+7)^2)
= sqrt ( 0^2 + 11^ 2 )
= sqrt ( 11^2)
= 11
Solution by contemplation!
Note the x coordinate of both points is the same (i.e. -1) This means the line joining the points is vertical and its length is simply the difference of the y coordinates: 4 - (-7) = 4 + 7 = 11
Thank you,

Answer:
sec Θ = 
Step-by-step explanation:
Using the trigonometric identity
sec²Θ = tan²Θ + 1
Since 270° < Θ < 360° ← that is fourth quadrant, then
sec Θ > 0, thus
sec²Θ = (- 
)² + 1 = 
+ 1 = 
, then
sec Θ = 
=
