Answer:
I think the solution to 4-7 is 3
Answer:
A: Designing the layout.
Step-by-step explanation:
Remember this: Geometry uses shapes.
Let's use the process of elimination.
D is eliminated because it does not use shapes.
C is eliminated because it uses numbers, not shapes.
B is eliminated because it uses science, not math or shapes.
A uses shapes in order to design a structure.
Answer:
40% decrease
50=100
30/50=x/100
30=60% of 50
40% decrease of 50 is 30

Answer
g(x) = e^ (x)^1/2
Derivate with respect to x
g'(x) = (1/2 -1)*x^(1/2 -1) * e^ (x)^1/2
g'(x) = (-1/2)*x^(-1/2) * e^ (x)^1/2
Let x be the amount invested at 7%, leaving 30000-x to be invested at 9%.
The equation is
2320 = 0.07 x + 0.09 (30000 - x)
2320 = -0.02 x + .09(30000)
0.02 x = .09(30000) - 2320
x = ( .09(30000) - 2320) / .02
x = 19000
Answer: $19000 at 7%, $11000 at 9%
Check:
19000(.07)+11000(.09) = 2320, good
