Given:
Fixed charges = $40
Variable charges = $1.70 for each mile.
To find:
The equation that represents the total cost y for x miles towed.
Find the y-intercept and interpret its meaning in the context of the situation.
Solution:
Let y be the total cost for x miles.
Fixed charges = $40
Variable charges for 1 mile = $1.70
Variable charges for x mile = $1.70x
Now,
Total changes = Fixed charges + Variable changes

Therefore, the required equation is
.
Putting x=0 in the above equation, we get



Therefore, the y-intercept is 40. It means the charges to hook a car is $40 if it is towed 0 miles.
Answer:
300 kcal of energy.
Explanation:
Grass produces 30,000 kcal of energy through the process of photosynthesis. The zebra eat this grass and would acquire 3000 kcal of energy because only 10% of energy will transferred from one trophic level to another. In this way, when the cheetah feed on zebra, it acquire 300 kcal of energy and again 10% of energy is transferred from zebra to cheetah while the remaining release in the atmosphere in the form of heat energy.
By predicting how the sodium-potassium pump becomes integrated into outer cell membrane. The prediction that is false is the mRNA coding into sodium pump is translated into the pump on two ribosomes.
<h3>What is sodium-potassium pump?</h3>
The sodium-potassium pump is an enzyme (an electrogenic transmembrane ATPase) present in the membrane of all animal cells. It is also known as sodium-potassium adenosine triphosphatase, Na+/K+-ATPase, or sodium-potassium ATPase. It serves a number of purposes in cell physiology.
The enzyme Na+/K+-ATPase is activated (i.e. it uses energy from ATP). Three sodium ions are exported and two potassium ions are imported for each ATP molecule used by the pump. As a result, each pump cycle results in the net export of one positive charge.
There are four distinct sodium pump isoforms or subtypes in mammals. Each has distinct qualities and patterns of tissue expression. The P-type ATPase family includes this enzyme.
