Theo needs 12 feet of boards all together.
4 x 3 = 12
Answer:
100
Step-by-step explanation:
f(n+1)=-10 f(n)
f(1)=1
put n=1
f(2)=-10f(1)=-10×1=-10
put n=2
f(3)=-10f(2)=-10×-10=100
X^2 + x - 6
------------- <= 0
x - 7
(x + 3)(x - 2)
---------------- <= 0
x - 7
2 critical values are x = -3 and x = 2
if x <= -3 the the function <= 0 so that's one part of the solution
also x >= 2
x must be < 7 if its = 7 then the function is indeterminate. and values between 2 and 7 will give negative valu to function
The answer is choice A.
Answer:
π(12.1)²
Step-by-step explanation:
12.1 is the radius
Formula for base = πr²
= π(12.1)²
F(x) = 4x + 3
the domain: Df = R
g(x) = -2x + 5
the domain: Dg = R
Df = Dg therefore (f · g)(x) = f(x) · g(x)
f(5) = 4 · 5 + 3 = 20 + 3 = 23
g(5) = -2 · 5 + 5 = -10 + 5 = -5
(f · g)(5) = f(5) · g(5) = 23 · (-5) = -115
