Complete Question
Marla sawed a 12-meter wood plank into 8 equal pieces. Which statement best explains how Marla cut the wood plank?
a) She cut the wood into pieces that are each 1/3 meter long.
b) She cut the wood into pieces that are each 1/2 meter long.
c) She cut the wood into pieces that are each 1 meter long.
d) She cut the wood into pieces that are each 1 1/2 meter long.
Answer:
d) She cut the wood into pieces that are each 1 1/2 meter long.
Step-by-step explanation:
Marla sawed a 12-meter wood plank into 8 equal pieces.
Hence,
8 equal pieces = 12 meter
1 equal pieces = x meter
Cross Multiply
8 × x = 1 × 12
x = 12/8 meters
x = 3/2 meters long
x = 1 1/2 meters long.
Therefore, Option d is the correct Option
Answer:
y intercept is 0
Step-by-step explanation:
y=2/3x+b
if x=0 y=0 (0,0)
if x=3, y=2 (3,2)
y=2/3x+b
2=2+b
b=0

Answer: Only first two are exponential growth function and last three functions are exponential decay functions.</h3>
Step-by-step explanation: We need to describe exponential growth or decay for the given functions.
The standard exponential function equation is
.
Where a is the initial value and b is the growth factor.
Note: If value of b > 1, it would be an exponential growth and if b < 1, it would be an exponential decay.
Let us check them one by one.
=> 
=>
.
Value of b is 1.008 > 1, therefor it's an exponential growth function.
y=250(1+0.004)^t, also have b>1 therefor it's an exponential growth function.
All other functions has b values less than 1, therefore only first two are exponential growth function and last three functions are exponential decay functions.
