Rounded it is 11.7 cubic cm.
N + 3n+4 + 4n-1 = 59
8n + 3 = 59
8n = 56
n = 7
The sides are 7, 3(7)+4, 4(7)-1
The three side lenght are 7, 25, 27
Answer:
13/15
Step-by-step explanation:
I assume you mean the ratio 4/5 : 12/13
Ratio means division, so it's 4/5 / 12/13
Multiply by reciprocal: 4/5 * 13/12 = 13/15
30 because 0.3 * 100 = 30
Try this option:
the rule: if f(-x)=f(x), then the function f(x) is even, if f(-x)=-f(x) then the function is odd.
1. f(x)=-5x⁴-2;
if to substitute x→(-x), then f(-x)=-5*(-x)⁴-2; ⇔ f(-x)=-5x⁴-2, in other words f(x)=f(-x), it means that this function is even.
2. f(x)=x³+2x.
if to substitute x→(-x), then f(-x)=(-x)³+2*(-x); ⇔ f(-x)=-(x³+2x), in other words f(-x)=-f(x), it means that this function is odd.
