Answer:
4.52 x 10
Step-by-step explanation:
45.2 in scientific notation, move the point one place to the left , it becomes
4.52 x 10
If you mean to say to find the 11th term, then know that this is an arithmetic sequence (where you have a common difference).
The common difference in this case is -2.
The formula for finding any term in an arithmetic sequence (specifically the explicit formula) is:
where a_n is the term, a_1 is the first term, n is the term number (position) and d is the common difference.
Let's substitute the corresponding values to the formula.
The 11th term is -17.
Answer:
P = 10
Step-by-step explanation:
First, find the unit rate.
Since the car travels 476 miles with 14 gallons of gas, then 476/14 = 34, so the car can travel 34 miles per gallon.
The distance is 34 times the number of gallons
d = 34g
Now you are given 578 miles, and you need to find the gallons.
578 = 34g
Solve for g by dividing both sides by 34.
g = 17
He needs 17 gallons.
<u>Answer-</u>
<em>The cubic equation-</em>
<em></em>
<em>Milk consumption in 1994 was </em><em>58.4 pounds.</em>
<u>Solution-</u>
The general form of a cubic model is,
x = input variable = year - 2000 i.e number years after 2000
y = output variable = milk consumed in pounds
Then putting the values from the table,
--------------------------1
-------------2
-------------3
------------4
Solving equations (1), (2), (3) and (4) simultaneously we get,
So, the equation becomes,
In order to get the milk consumption in 1994, putting x=94
Therefore, milk consumption in 1994 was 58.4 pounds.
