Answer:
convex
Step-by-step explanation:
its convex because it has six outer perimeters
2 over 45 just so that you know
Answer:
y= 4 sinx/2-3
Step-by-step explanation:
y= a sin2πt/T
where : a is the amplitude , t is the time in seconds, and T is a period of wave is seconds.
y=A sin (B(x+C)) +D
amplitude A = 4
2π/B is period = 4
C is the phase shift = -2
D is vertical shifts = -2
now substitute the numbers in the equation :
y= A sin ( B(x+C)) + D
y= 4 sin (4(x-2) -2
y=4sin(4x-8)-2
Answer: The interest rate can he afford to pay on his | loan =7.5%
Step-by-step explanation:
Given: Principal amount = 375,000
Interest amount per year = $28,125
Interest percentage = 
Hence, The interest rate can he afford to pay on his | loan =7.5%
If he saves $ 8 each week...and his mom is giving him 0.25 for each dollar, then he will have (8 + 0.25(8)) = 8 + 2 = $ 10 per week
10w = 100.....with w being the number of weeks
w = 100/10
w = 10...so he will have it in 10 weeks <==
