<h2>Answer :</h2>

Error (e) = 12 - 9 = $ 3

assumed value (a) = $ 9

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

$\mathrm{ \% \: error =\dfrac{3}{9} ×100}$

$\mathrm{ \% \: error = \dfrac{1}{3} ×100}$

$\mathrm{ \% \: error = 33.33 \%}$

F(x) = 300(1-.06)^5
f(x) = 300(.7339040224...)
f(x) = 220.17120672
After 5 years, the club should still have 220 members.

Graph each equation by using the x- and y-intercepts

Alex Ar [27]

You have the correct graph. Plug in y = 0 and solve for x to get x = -3. Do the same for x = 0 and solve to get y = -3.

x intercept = -3 which is the point (-3,0)
y intercept = -3 which is the point (0,-3)

Nice job on getting the correct graph with the correct points.

Jacob needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.

dalvyx [7]

An inequality that represent the number of cans, c, that Jacob must still collect is $c\geq 56$ .

<u>Step-by-step explanation:</u>

Here we have , Jacob needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. We need to solve the following :

Write and solve an inequality to represent the number of cans, c, that Jacob must still collect.

Jacob has collected 64 cans . Jacob need to collect at least 120 cans for a food drive to earn community service credit , Let Number of cans that Jacob have to collect is c , So following is the inequality for above scenario:

⇒ $c+64\geq 120$

⇒ $(c+64)-64\geq 120-64$

⇒ $c\geq 56$

Therefore , An inequality that represent the number of cans, c, that Jacob must still collect is $c\geq 56$ .
