Answer:
71°
Step-by-step explanation:
3x° + (x - 11)° + (2x - 55)° = 360°
3x + x - 11 + 2x - 55 = 360°
6x - 66 = 360°
6x = 360° + 66°
6x = 426°
x = 71°
Step-by-step explanation:
u/7 - 1 < 1
u/7 < 1 + 1
u/7 < 2
u < 2 x 7
u < 14
Answer:
Her income increase by 27.5% from 2004 to 2007
Step-by-step explanation:
Step 1 : Kieya's income in 2004 was $40,000
Step 2 : Kieya's income in 2007 was $51,000
Step 3 : Calculate difference in $
Income in 2007 - Income in 2004 = Increase (+ve) or decrease (-ve) in income
51000 - 40000 = 11000 increase in income
Step 4 : Calculate difference in terms of percentage
<u>Income of 2007-Income of 2004</u> x 100
Income of 2004
<u>51000-40000</u> x 100
40000
= 0.275 x 100
= 27.5 %

Answer:
y = C1x^(-1/2) cosx + C2x^(-1/2) sinx
Step-by-step explanation:
Given that
y1 = x^(-1/2) cosx
y2 = x^(-1/2) sinx
are linearly independent solutions of the nonhomogeneous equation
x²y'' + xy' + x² − 1 4y = x^(3/2)
Then the general equation of the differential equation can be written as
y = C1y1 + C2y2
y = C1x^(-1/2) cosx + C2x^(-1/2) sinx
The numbers are 16 and 32. 32 is 16 more than 16. 16+32=48
