It is graph w because it starts at a price of 40 and goes up by 20 every hour.
Answer:
90 clockwise
Step-by-step explanation:
rotate it by 90 degrees. it lines up
Answer:
(-1,5), (0,4) ,(1,3) ,(3,1) is linear so dont pick it
(-4,-7), (-2,-6), (2,-4), (4,-3) is linear
you know what I'll just say it wait a minute is there like a other option
Step-by-step explanation:
U can tell by graphing them out yourself and if u see a straight line then it linear, and if you see a curved loop then it's non- linear. but I'll do it :)
Answer: SAS
Step-by-step explanation:
The Side Angle Side (SAS) postulates that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent
Alright, so you have the basic formula- good.
You have the A value (400), the interest rate r (7.5% -> .075 in decimal), and the final P value (8500). So, we only need to solve for t.
8500 = (400)(1+.075)^t
/400 /400
21.25 = 1.075^t
logarithms are the inverse of exponents, basically, if you have an example like
y = b^x, then a logarithm inverts it, logy(baseb)=x
Makes sense if you consider a power of ten.
1000 = 10^3
if you put logbase10(1000), you'll get 3.
Anyways, though, to solve the problem make a log with a base of 1.075 in your calculator
log21.25(base 1.075) = t
also, because of rules of change of base (might want to look this up to clarify), you can write this as log(21.25)/log(1.075) = t
Thus, t is 42.26118551.
Rounded to hundredths, t=42.26
