Answer:
D. -3/2
Step-by-step explanation:
if two lines are perpendicular, their gradients will multiply to give -1
For example, green line, m=2/3
2/3 × M2 =-1
M2=-3/2
Answer:
Step-by-step explanation:
The volume v in cubic feet of a shipping box is modeled by the polynomial function V(x)=x^3-2x^2-19x+20, where X is the length of the box. To determine if x = - 2 is not a zero of the polynomial function, we would substitute x = - 2 into the polynomial function, V(x)=x^3-2x^2-19x+20. If the result is not zero, it means that x = - 2 not a zero of the polynomial function. Therefore
(-2)^3-2(-2)^2-19(-2)+20
= - 8 - 8 + 38 + 20 = 42
Since 42 is not equal to 0, then x = - 2 not a zero of the polynomial function.

Since you can 4 pieces from 1 foot, you multiply 4 by 5 and you get 20 pieces.
Answer:
10.626
Step-by-step explanation:
There's multiple ways to go about it. See how
5.06 * 2.1 = (5 + 0.06)(2 + 0.1) = 5*2 + 0.06*2 + 5*0.1 + 0.06*0.1 =
= 10 + 0.12 + 0.5 + 0.006 = 10.626
Please notice how breaking up the product into smaller parts has let us make all the computations without too much hassle.
