Answer:
Step-by-step explanation:
1+sin²(a) +cos²(a) =2
note : for all a in R : sin²(a) +cos²(a) =1
so : 1+sin²(a) +cos²(a) = 1+1 =2
10% = 25
1% = 25 ÷ 10 = 2.5
100% = 2.5 x 100 = 250
Answer: 250 t-shirts
Easy peasy
slope intercept form is y=mx+b where m=slope
we see taht we have y=7/2x-2
therefor m=slope=7/2
the slope is 7/2
