Answer:
1. 21.6
2. 54
3.16.22
Step-by-step explanation:
1. 3(1.8)(4)
2. 7.5(1.8)(4)
3. (1.4)(4) + (5.9)(1.8)
Answer:
Step-by-step explanation:
Simplifying
N(t) = 300.9
Multiply N * t tN = 300.9 Solving tN = 300.9
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Divide each side by 'N'. t = 300.9N-1
Simplifying t = 300.9N-1
Answer:
2x²-2x-24
Step-by-step explanation:
Something has roots of 4 and -3 we can write
(x-4)(x+3)
We then attach a constant, a that will ensure that it passes through the correct point
a(x-4)(x+3)
now plug in the numbers and solve for a
a(3-4)(3+3)= -12
a(-1)(6)= -12
-6a= -12
a=2
So we have
2(x-4)(x+3)
and now it's just a matter of mulitplying/simplifying things
(x-4)(x+3)= x²-x-12
2(x²-x-12)= 2x²-2x-24
