The average miles per gallon is 379/16=23.69 mpg
Answer: 0.9
Step-by-step explanation:
<u>Let x be the number</u>
<u>Determine the value of the number</u>
x² = 81
√x² = √81
x = 9
<u>Find the 10% of the number</u>
Final number = rate of percentage × original number
Final number = 10% × 9
Final number =

Hello ,
there are 12 combinations

8 10 3 0
9 15 0 1
10 15 2 0
11 20 1 0
12 25 0 0
DIM x AS INTEGER, y AS INTEGER, z AS INTEGER, k AS INTEGER
'OPEN "c:\nosdevoirs\monnaie.sol" FOR OUTPUT AS #1
k = 0
FOR x = 0 TO 25
FOR y = 0 TO 5
FOR z = 0 TO 3
IF x + 5 * y + 10 * z = 25 THEN
k = k + 1
PRINT k, x, y, z
' PRINT #1, k, x, y, z
END IF

Answer:
Problem 20)
Problem 21)
A)
The velocity function is:
The acceleration function is:
B)
Step-by-step explanation:
Problem 20)
We want to differentiate the equation:
We can take the natural log of both sides. This yields:
Since ln(aᵇ) = bln(a):
Take the derivative of both sides with respect to <em>x: </em>
<em /><em />
Implicitly differentiate the left and use the product rule on the right. Therefore:
Simplify:
Simplify and multiply both sides by <em>y: </em>
<em /><em />
Since <em>y</em> = (cos x)ˣ:
Problem 21)
We are given the position function of a particle:
A)
Recall that the velocity function is the derivative of the position function. Hence:
Differentiate:
The acceleration function is the derivative of the velocity function. Hence:
Differentiate:
B)
The position at <em>t</em> = 0 will be:
The velocity at <em>t</em> = 0 will be:
And the acceleration at <em>t</em> = 0 will be:
