An auto mechanic ordered eight car spark plugs and four truck spark plugs. Car spark plugs cost $.75, and truck spark plugs cost
Nataly_w [17]
The first thing we should know is the definition of commutative property.
 Commutative property:
 The distributive property of multiplication over addition in elementary algebra is that in which the result of a number multiplied by the sum of two or more addends is equal to the sum of the products of each summand by that number. In algebraic terms we have then:
 4 * ((2 * 0.75) + (3)) = (8 * 0.75) + (4 * 3) = 6 + 12 = 18 $
 answer:
 the total cost of these parts is $ 18

Find an equation for the nth term in the following sequence:<br> 2, 8, 32, 128, 512...
seraphim [82]

Answer:

a_n = 2(4) ^{n-1}

Step-by-step explanation:

The sequence shown matches that of a geometric sequence of radius 4. To prove it, divide the term \frac{a_{n + 1}}{a_n} and check that \frac{a_{n + 1}}{a_n}=4

Then the formula that represents this sequence is:

a_n = a_1(r)^{n-1}

Where a_1 is the first term of the series = 2 and r is the radius of convergence = 4.

Then the equation is:

a_n = 2(4) ^{n-1}

Justin launches a rocket straight up into the air. The table below gives the height(t) of the rocket (in meters) at a few times
Papessa [141]

Using it's formula, the average rates of change are given as follows:

a) 30 meters per second.

b) -10 meters per second.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output divided by the change in the input.</u> Hence, over an interval [a,b], the rate is given by the following equation:

r = \frac{f(b) - f(a)}{b - a}

For item a, taking the data from the table, we have that:

  • f(0) = 0.
  • f(4.6) = 138.

Hence the rate is given as follows:

r = (138 - 0)/(4.6 - 0) = 30 meters per second.

For item b, taking the data from the table, we have that:

  • f(9.2) = 23.
  • f(11.5) = 0.

Hence the rate is given as follows:

r = (0 - 23)/(11.5 - 9.2) = -10 meters per second.
