Hi there!
We can look at each function, f(x) and g(x), to determine which is exponential.
Use slope formula: m = y2-y1/x2-x1
f(x) starts off with a slope at about $1800/year, but becomes about $1100/year.
g(x) starts off with a slope of about $1500/year, but becomes about $1874/year.
Thus, g(x) is exponential, because g(x)'s slope is increasing across the interval.
A = pi (r)^2
so with 222r
circle changes by a factor of 222^2
126/7=18 (so that's 18 ounces per bag)
now subtract the 3 ounces that were added to each bag:
18-3=15
so the old almond bag weighed 15 ounces
Here is an example on how you should do your multiplication. The website should give you your answer to any multiplication.
Hope this helps love!! <3
Julie wants to express $108 in 6 weeks as a unit rate.
Her errors are:
$108 = $54 (Not true)
6 weeks = 3 weeks (Not true).
Instead,
The correct unit rate is 18 $/week.
