(07.03 LC) The steps below show the incomplete solution to find the value of q for the equation 4q − 2q − 4 = −1 + 21: Step 1: 4

Elza [17]

Answer:

3: 2q − 4 = 20

Step-by-step explanation:

Solve for q:

2 q - 4 = 20

Add 4 to both sides:

2 q + (4 - 4) = 4 + 20

4 - 4 = 0:

2 q = 20 + 4

20 + 4 = 24:

2 q = 24

Divide both sides of 2 q = 24 by 2:

(2 q)/2 = 24/2

2/2 = 1:

q = 24/2

The gcd of 24 and 2 is 2, so 24/2 = (2×12)/(2×1) = 2/2×12 = 12:

Answer: q = 12

According to data from a General Motors study, the average speed of your trip A (in miles per hour) is related to the number of

polet [3.4K]

Answer:

$(a)\hspace{3}-79.61mi/h^2$

$(b)\hspace{3}-4.36mi/h^2$

Step-by-step explanation:

Let's rewrite the equation as:

$A=26.5*(x^{-0.45 })$

Now, let's find its derivate:

$\frac{dA}{dx} =(-0.45)*(26.5)*x^{-0.45-1} =-11.925*x^{-1.45} =-\frac{11.925}{x^{1.45} }$

Let's evaluate x=0.27 and x=2:

$\frac{dA}{dx} \left \{ {x=0.27}} \right. =-\frac{11.925}{0.27^{1.45} } =-79.61mi/h^2$

$\frac{dA}{dx} \left \{ {x=2}} \right. =-\frac{11.925}{2^{1.45} } =-4.36mi/h^2$

Keep in mind that when we derivate A(average speed) we find the average acceleration, thats why the result is given in mi/h^2, also it explains the minus sign, because for every stop you make on the trip you are decelerating.
