Let f(x)
40e^.06t. What is the average rate of change of f over the
interval [0,3]? Give your answer as a decimal with one place of
accuracy to the right of the decimal point.
Answer:
[tex]R= 2.6[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 40e^{.06t[/tex]
[tex][a,b] = [0,3][/tex]
Required
Determine the average rate of change (R)
This is calculated as follows:
[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]
Where
[tex]a = 0[/tex] and [tex]b = 3[/tex]
Substitute 0 for a and 3 for b
[tex]R = \frac{f(3) - f(0)}{3 - 0}[/tex]
[tex]R = \frac{f(3) - f(0)}{3}[/tex]
[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]
Calculate f(3)
[tex]f(x) = 40e^{.06t[/tex]
[tex]f(3) = 40e^{.06*3}[/tex]
[tex]f(3) = 40e^{0.18}[/tex]
[tex]f(3) = 40 * 1.197[/tex]
[tex]f(3) = 47.88[/tex]
Calculate f(0)
[tex]f(x) = 40e^{.06t[/tex]
[tex]f(0) = 40e^{.06*0}[/tex]
[tex]f(0) = 40e^{0}[/tex]
[tex]f(0) = 40*1[/tex]
[tex]f(0) = 40[/tex]
So, the expression:
[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]
[tex]R= \frac{1}{3}[47.88 - 40][/tex]
[tex]R= \frac{1}{3}[7.88][/tex]
[tex]R= 2.62666666667[/tex]
[tex]R= 2.6[/tex]
Hence, the average rate of change is approximately 2.6

Which inquality is graft below?
Answer:
Option C - 2x + y > 2
Step-by-step explanation:
We don’t have to do some serious math here. We can already eliminate half of the options just looking at it, because the graph has a dotted line, which means it does not include those values.
So, choses A and B are eliminated because the inequality shows the ≥ and ≤ symbol, which means that it does include those values. It’s either C or D because they have the > and < symbol, which means that the inequality does not include those values.
To have a better look at the inequalities, write them in slope-intercept form, which is y=mx+b:
Option C: y > -2x + 2
Option D: y < -2x +2
Just looking at the inequlaity symbol, we can tell that Option C is the correct one because it shows that all the y-values are greater than -2x + 2. Which is true because it’s shaded above the line. When it’s shaded above the line, it means that the y-values are greater.
To make sure my answer was correct, I graphed Option C. The image below shows Option C (2x + y > 2) graphed.
Hope this helps! :)
What is the solution to the system of equations?
y = 1/3x -10

What is 4(2 + a) = 24
a=
Answer:
2/5
Step-by-step explanation:
Rearrange terms:
4(2 + a) = 24a
4(a + 2) = 24a
Distrbute:
4(a + 2) = 24a
4a + 8 = 24a
Subtract 8 from both sides of the equation:
4a + 8 = 24a
4a + 8-8 = 24a-8
Simplify:
4a = 24a - 8
Subtract 24a from both sides of the equation:
4a = 24a - 8
4a - 24a = 24a - 8 - 24a
Combine like terms:
-20a = -8
Divide both sides of the equation by the same term:
-20a = -8
-20a/-20 = -8/-20
Simplify:
Cancel terms that are in both the numerator and denominator
Divide the numbers
a = 2/5
I hope that helps! :D

State all integer values of x in the interval (2,8) that satisfy the following inequality:
5x + 4 > 19
Answer:
3,4,5,6 and 7
Step-by-step explanation:
Given
[tex]5x + 4 \ge 19[/tex]
Required
State the values of x within 2 and 8
[tex]5x + 4 \ge 19[/tex]
Collect Like Terms
[tex]5x \ge 19 - 4[/tex]
[tex]5x \ge 15[/tex]
Divide both sides by 5
[tex]\frac{5x}{5} \ge \frac{15}{5}[/tex]
[tex]x \ge 3[/tex]
(2,8) is an open interval which means that 2 and 8 are not inclusive of the values of x.
So:
The values of [tex]x \ge 3[/tex] are: 3,4,5,6 and 7

Karen finished watching a movie at 1:10pm. The movie lasted 1 hour 38 minutes. Click on the time Karen started watching the movie.
Answer:
11:32
Step-by-step explanation:
Karen probably started watching the movie at 11:32 because 11:32 + 1:38 = 1:10.
32+ 38= 70, so 11:00 + 70 = 12:10, plus 1 hour = 1:10.

Step-by-step explanation:
So basically what you want to do is divide how much ounces of oats you need in total by the amount the spoon will hold.
Total amount of oats needed ÷ How much the spoon holds = ?
So now you just add your values:
26 ÷ 4 = ?
26 ÷ 4 = 6.5
6.5 IS greater than 1
So, your equation could be one of these two:
Total oats needed ÷ How many oats the spoon will hold = ?
OR
26 ÷ 4 = ?
