Step-by-step answer:
The base of the exponential function is 1.29 for 7 days, as in
f(x) = 86*(1.29)^x
The new rate for days can be calculated by dividing x by 7 (where x remains the number of weeks), namely
f(x) = 86*1.29^(x/7)
Using the law of exponents, b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x
we simplify by putting b=1.29, a=7 to get
f(x) = 86*(1.29^(1/7))^x
f(x) = 86*(1.037)^x since 1.29^(1/7) evaluates to 1.037
Rounding 1.037 to 1.04 we get a (VERY) approximate function
f(x) = 86 * (1.04^x)
1.04 is very approximate because 1.04^7 is supposed to get back 1.29, but it is actually 1.316, while 1.037^7 gives 1.2896, much closer to 1.29.

It’s either B or D. I’m sorry I’m not so sure but I think it’s either one of those.
#3 describes an isosceles triangle.
#5 describes an equilateral triangle.
#7 describes a right triangle.
Answer:
U' = (0,2)
V' = (0,5)
W' = (-5,5)
Step-by-step explanation:
To get these, you can subtract 2 from the x-value because they are moving 2 units to the left and add 2 to the y-value because they are moving 2 units up.
