Answer:

n = 3

Explanation:

−5n+8=−7

Step 1: Subtract 8 from both sides.

−5n+8−8=−7−8

−5n=−15

Step 2: Divide both sides by -5.

-5n/-5 = -15/-5

n = 3

The position of an atom moving inside a cathode ray tube is given by the function f(t) = t^3− 4t^2 + 3t where t is in seconds an
murzikaleks [220]

Answer:

A

Step-by-step explanation:

The position of an atom moving inside a cathode ray tube is given by the function:

f(t)=t^3-4t^2+3t

Where f(t) is in meters and <em>t</em> is in seconds.

And we want to determine its instantaneous velocity at <em>t</em> = 2.5 seconds.

The velocity function is the derivative of the position function. Thus, find the derivative of the function:

<em />f'(t)=3t^2-8t+3<em />

<em />

Then the instantaneous velocity at <em>t</em> = 2.5 will be:

f'(2.5)=3(2.5)^2-8(2.5)+3=1.75\text{ m/sec}

Our answer is A.

suter [353]

Answer:

Option A: 1.50x +15

Option B: 3x

After 10 rides, the total cost of each option will be the same. This total cost is $30

Step-by-step explanation:

X represents how many rides you take. After 10 rides, the total cost of each option will be the same. To find that, keep plugging in numbers into x until the numbers are the same. This total cost where the numbers are the same is $30.

Rays dad bought a vintage car for $23000. If it increases in value 3% a year, how much will it be worth in 7 years?
kirill115 [55]

Answer:

It should be $27830 if I'm reading this right.

Step-by-step explanation:

3% of $23000 is $690

$690 * 7 = $4830

$23000 + $4830 = $27830

F(x)=x^3-9x<br> What is the average rate of change of f over the interval (1,6]?
Rzqust [24]

Answer:

34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

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

Here [ a, b ] = [ 1, 6 ]

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8, thus

average rate of change = \frac{162-(-8)}{6-1} = \frac{170}{5} = 34
