Answer:
The Martian satellite Phobos travels in an approximately circular orbit of radius 9.4x10^6m with a period of 7 h39 min. Calculate the mass of Mars from this information.
Answer:
Sample space: {1, 2, 3, 4, 5, 6}
Simple event
Step-by-step explanation:
Sample space is a list of all the possible outcomes.
This is a simple event because you are only doing one event, such as rolling a die.
A compound event would be multiple simple events, such as flipping a coin <em>and </em>choosing a marble from a bag.
d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let p represent the bacteria population in thousand after d days.
Since each day, the bacteria population grows by a factor of 2, hence:

Hence, d = log₂p represents a logarithmic function
The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

Answer:
its close 9.45
Step-by-step explanation:
7(x+9)=132
7x+63=132
7x=132-63
7x=69
x=69/7
x=9.45
Answer:
21 days
Step-by-step explanation:
in one week, there are 7 days
hence in 3 weeks, there are 7 x 3 = 21 days
