Answer:
f(x) = 2x3 + 4
Stretch vertically be a factor of 2:
f(x) = 2*2x3 + 4 = 4x3 + 4
Shift 5 units to the left:
f(x) = 4(x+5)3 + 4
Answer:
![\frac{s}{2t}](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7B2t%7D)
Step-by-step explanation:
When you have exponents above a like term and they are being multiplied together, you add them.
For example:
![a^{x} *a^{y} = a^{x + y}](https://tex.z-dn.net/?f=a%5E%7Bx%7D%20%2Aa%5E%7By%7D%20%3D%20a%5E%7Bx%20%2B%20y%7D)
So let's group like terms in the numerator:
We can add terms like in the example.
![4 r^{-2} s^{-3} t](https://tex.z-dn.net/?f=4%20r%5E%7B-2%7D%20s%5E%7B-3%7D%20t)
Let's rearrange the denominator.
![8r^{-2} s^{-4} t^{2}](https://tex.z-dn.net/?f=8r%5E%7B-2%7D%20s%5E%7B-4%7D%20t%5E%7B2%7D)
Now we have:
Cancel like terms
4/8 = 1/2
= 1 So it cancels
= s Since s is raised to the -1 it goes on top and becomes s.
![t / t^{2} = 1/t](https://tex.z-dn.net/?f=t%20%2F%20t%5E%7B2%7D%20%20%3D%201%2Ft)
Now we combine everything back together:
![\frac{s}{2t}](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7B2t%7D)
Answer and explanation:
Discrete random variables can be counted as integers and you can't divide them. Continuous random variables are counted as real numbers and are magnitudes that can´t be counted as an exact number (there will always be an uncertainty in the measurement).
a. The random variable is continuous. Distance is a measurement.
b. The random variable is discrete. You can count how many people are sitting at a computer.
c. The random variable is continuous. Weight is a measurement.
d. The random variable is discrete. You can count how many fishes were caught.
e. The random variable is discrete. You can count how many hints a web site had.
16*8=128
12*12=144
128
+ 144
$272

Answer:
Infinitely many solutions.
Step-by-step explanation:
4v=6v-2v Combine like terms.
4v=4v These are already equal without diving, so there are infinitely many solutions.
Hope this helps and have a nice day ❤
