1. Continuous Compounding A certain investment is
subject to continuous compounding. The value of
the investment after t years is given by
V = 5000e0.05t dollars.
a. Make a graph of the value of the investment over
the first 20 years.
4. E
C
How do I make a graph
The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.
We are provided with the equation V = 5000[tex]e^{0.05t}[/tex]
The equation can be simplified as
V = 5000 e0* (0.05t)
V= 250t
This linear equation can be plotted for different values of t which are
If t=0, V = 0
If t=1, V = 250
If t=2, V = 500
If t=3, V = 750
If t=4, V = 1000
If t=5, V = 1250
If t=6, V = 1500
If t=7, V = 1750
If t=8, V = 2000
If t=9, V = 2250
If t=10, V = 2500
If t=11, V = 2750
If t=12, V = 3000
If t=13, V = 3250
If t=14, V = 3500
If t=15, V = 3750
If t=16, V = 4000
If t=17, V = 4250
If t=18, V = 4500
If t=19, V = 4750
If t=20, V =5000
Now, we just have plot these 20 coordinates
The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.

Which of the following can be used to evaluate the series 9 k=1 2(4) k=1?
Answer:
Option (3)
Step-by-step explanation:
Given expression represents the sum of k terms of a geometric sequence.
[tex]\sum_{k=1}^{9}2(4)^{k-1}[/tex]
Since, formula to calculate the sum of a geometric sequence is given by,
[tex]\sum_{n=1}^{n}a(r)^{n-1}=\frac{a(1-r^n)}{1-r}[/tex]
By this formula,sum of 9 terms of the given sequence will be,
[tex]\sum_{k=1}^{9}2(4)^{k-1}=\frac{2(1-4^9)}{1-4}[/tex]
Therefore, Option (3) will be the answer.

Which of the following types of angles DO NOT have equal measure in the figure shown?
Choose one 4 points
O Alternate Interior Angles
Alternate Exterior Angles
O Adjacent Angles
O Corresponding Angles
5/6
7/8
1/2
3/4
Intersecting Lines
Out of the following types of angles adjacent angles do not have equal measure.
Here, from the given figure, we can see that the 2 horizontal lines are parallel to each other and a transversal is drawn between them.
When 2 lines are parallel and joined by a transversal, any two pairs or alternate exterior angles, alternate interior angles and corresponding angles will be equal.
However, any to pairs of adjacent angle will not be equal. The sum of a pair of adjacent angles that lie on the straight line is 180°.
Here, one pair of adjacent angles is ∠1 and ∠2. Thus-
∠1 + ∠2 = 180
∠1 and ∠2 will be equal only when both of them are 90° each. Here, we are not given that they are 90.
Hence, out of the following types of angles adjacent angles do not have equal measure.

Given b = - 14 which equation is true
A. -28 + 2b = 53
B. 2b + 7 = 20
C. 6/7 + 18 = 16
D. b/2 + 7.4 = 1.4
Answer:
b/2 + 7.4 = 1.4 thus D. is the answer
Step-by-step explanation:
Solve for b:
b/2 + 7.4 = 1.4
Put each term in b/2 + 7.4 over the common denominator 2: b/2 + 7.4 = b/2 + 14.8/2:
(b/2 + 14.8/2) = 1.4
b/2 + 14.8/2 = (b + 14.8)/2:
((b + 14.8)/2) = 1.4
Multiply both sides of (b + 14.8)/2 = 1.4 by 2:
(2 (b + 14.8))/2 = 2×1.4
(2 (b + 14.8))/2 = 2/2×(b + 14.8) = b + 14.8:
b + 14.8 = 2×1.4
2×1.4 = 2.8:
b + 14.8 = 2.8
Subtract 14.8 from both sides:
b + (14.8 - 14.8) = 2.8 - 14.8
14.8 - 14.8 = 0:
b = 2.8 - 14.8
2.8 - 14.8 = -12:
Answer: b = -12

A rental company charges $70 a day and 20 cents a mile for renting a truck. Michael rents a truck for 3 days, and his bill came to $295. How many miles did he drive?
Michael drove 1125 miles and paid $295 for renting the truck for 3 days
Rental company charges per day = $70
Rental company charges per mile = $0.20
Number of days truck is rented by Michael = 3 days
The total amount paid by Michael for the truck = $295
Let x be the number of miles Michael drives the truck
Formulating the equation using the information given in the question:
295 = 70 + 0.20(x)
295-70 = 0.20(x)
225 = 0.20(x)
x = 1125 miles
Therefore, the total miles driven by Michael is 1125 miles.
Michael paid $295 for driving the truck for 1125 miles and renting it for 3 days.

Mai earns $7 per hour mowing her neighbors' lawns. She also earned
$14 for hauling away bags of recyclables for some neighbors. Priya
babysits her neighbor's children. She earns $8.40 per hour. Priya and
Mai have agreed to go to the movies the weekend after they have
earned the same amount of money for the same number of hours. How
many hours do they have to work before they can go to the movies?
How much will they have earned?
Answer:
10 hours, $84
Step-by-step explanation:
System of equations is:
7x+14=y
8.4x=y
Substitute to get:
7x+14=8.4x
subtract 7x from both sides
14=1.4x
x=10
So they will have to have worked for 10 hours
8.4*10=y
84=y
So they will have earned 84 dollars each
x=10 y=84

Bob's average golf score at his local course is 93.6 from a random sample of 34 rounds of golf. Assume that the population standard deviation for his golf score is 4.2. The 90% confidence interval around this sample mean is:_______.
a. (92.4, 94.8).
b. (89.0, 98.3).
c. (90.5, 96.7).
d. (93.2, 94.0).
Answer:
a. (92.4, 94.8)
Step-by-step explanation:
Given that:
Mean (m) = 93.6
Standard deviation (σ) = 4.2
Sample size (n) = 34
α = 90%
Confidence interval around sample mean :
Mean ± Zstatistic * s/√n
Z0.90 = 1.645 (Z probability calculator)
s / √n = 4.2 / √34 = 0.7202940
Lower limit = 93.6 - (1.645 * 0.7202940) = 92.41511637 = 92.4
Upper limit = 93.6 + (1.645 * 0.7202940) = 94.78488363 = 94.8
