Answer:
(B)-4
Step-by-step explanation:
From the table, consider the points (-4,-2), (-2,-10) and (-1,-14)
![\text{Slope, m }=\dfrac{y_2-y_1}{x_2-x_1} \\=\dfrac{-10-(-2)}{-2-(-4)} \\=\dfrac{-10+2}{-2+4} \\=\dfrac{-8}{2} \\\\m=-4](https://tex.z-dn.net/?f=%5Ctext%7BSlope%2C%20m%20%7D%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%5C%5C%3D%5Cdfrac%7B-10-%28-2%29%7D%7B-2-%28-4%29%7D%20%5C%5C%3D%5Cdfrac%7B-10%2B2%7D%7B-2%2B4%7D%20%5C%5C%3D%5Cdfrac%7B-8%7D%7B2%7D%20%5C%5C%5C%5Cm%3D-4)
The slope of the function is -4.
The correct option is B.
Answer:
Volume is 80 cc
Ratio is 23 skittles per 20 cubic centimeter
Volume of a skittle is .416 cubic centimeters per skittle
Step-by-step explanation:
Volume = l*w*h = 4*4*5 = 80 cubic centimeters
192 skittles / 80 cubic centimeters is the ratio. You have to simplify it though.
192/80=46/40 23 skittles per 20 cubic centimeters
The volume of a skittle is 80 cubic centimeters/192 skittles = .416 cm^3/skittle
A=future amount
P=present amount
r=rate in decimal
t=time in years
when A=2P, then that is double
A=Pe^(rt)
2P=Pe^(rt)
divide by P
2=e^(rt)
r=3.1% or 0.031 solve for t
2=e^(0.031t)
take the ln of both sides
ln(2)=0.031t
divide both sides by 0.031
(ln(2))/0.031=t
use calculator
22.359=t
round to tenth
22.4 years to double
