Answer:
exponential decay: A=(0.97)^t, y=3.7(0.2)^t,
exponential growth: y=(9/11)(4)^t, P=(7/9)(5/4)^t, V=0.8(9)^t, P=0.9(8.3)^t
neither: g(x)=2.1(x)
Step-by-step explanation:
exponential decay happens when the ratio (the value inside the parenthesis) is less than 1. exponential growth happens when the ratio is greater than 1.
Let's find the unit rates and compare. The hardware store's one is already given, so we only need to find the one for the stand.
85/4 = 0.2125
0.2125 > 0.19
You would want to buy at the store. Hope this helps!
Answer:
x = 14
< A = 58 degrees
< B = 52 degrees
< C = 70 degrees
Step-by-step explanation:
Recall that the addition of the three internal angles of a triangle must render 180 degrees, then we can write:
<A + <B + <C = 180
and now replace with the algebraic expressions given for each angle:
2(x + 15) + 3 x + 10 + 5 x = 180
eliminate parenthesis
2 x + 30 + 3 x + 10 + 5 x = 180
combine like terms
10 x + 40 = 180
subtract 40 from both sides
10 x = 140
divide both sides y 10 to isolate x
x = 14
Now that we know x, we can calculate each of the angles using the fiven expressions:
< A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees
< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees
< C = 5 x = 5 * 14 = 70 degrees
