The graph below shows the fine that a college student pays to the library based on the number of minutes a loaner laptop is overdue:
A graph is shown. The values on the x axis are 0, 2, 4, 6, 8. The values on the y axis are 0, 0.70, 1.40, 2.10, 2.80. Points are shown on ordered pairs 0, 0 and 2, 0.70 and 4, 1.40 and 6, 2.10. These points are joined by a line. The label on the x axis is Minutes Overdue. The title on the y axis is Fine.
Which statement best describes the point (0, 0) on the graph?
Answers
This graph shows an increasing linear trend. It shows that the fine is directly proportional with time. At time 0 minutes, the college student does not have to pay a fine because he hasn't even used the laptop yet. Therefore, the origin (0,0) signifies the starting point of the observation. But when he used 2 minutes of the time, he would pay $0.7. The trend goes on until he used up 6 minutes and paid a total of $2.1
Answer:
So the answer would be No fine is paid if the laptop is returned exactly at the time at which it is due

14/6
Now we can convert the improper fraction back into a proper fraction.
How many times does 6 fit into 14? 2 with a remainder of 2
The Fraction would be: 2 2/6 or reduced to 2 1/3
She used 2 1/3 yards of fabric.
The question asks for how much she has left so, we must subtract 2 1/3 from 3 1/2
However, we must have a common denominator to subtract.
To find this, we can list the multiples of both of the denominators:
2: 2,4,6,8,10
3: 3,6,9,12,15
The LCM (Lowest Common Denominator) is 6.

an ellipse has a center at the origin, a vertex along the major axis at (13, 0), and a focus at (12, 0). What is the equation of the ellipse?
Answers
Answer: The equation of the ellipse is
[tex]\dfrac{x^2}{169}+\dfrac{y^2}{25}=1.[/tex]
Step-by-step explanation: We are given to find the equation of an ellipse that has a center at the origin, a vertex along the major axis at (13, 0) and a focus at (12, 0).
Since the focus lies on the X-axis, so the standard equation of an ellipse with major axis as X-axis is given by
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
According to given information, we have
a vertex along the major axis, (a, 0) = (13, 0)
⇒ length of the major axis, a = 13,
co-ordinates of focus, (c, 0) = (12, 0)
⇒ c = 12.
We know that
[tex]c^2=a^2-b^2.[/tex]
Therefore,
[tex]12^2=13^2-b^2\\\\\Rightarrow 144=169-b^2\\\\\Rightarrow b^2=169-144\\\\\Rightarrow b^2=25\\\\\Rightarrow b=5.[/tex]
Thus, from equation (i), we get
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1\\\\\\\Rightarrow \dfrac{x^2}{13^2}+\dfrac{y^2}{5^2}=1\\\\\\\Rightarrow \dfrac{x^2}{169}+\dfrac{y^2}{25}=1.[/tex]
The equation of the ellipse is
[tex]\dfrac{x^2}{169}+\dfrac{y^2}{25}=1.[/tex]
The equation of the ellipse along the major axis at (13, 0), and a focus at (12, 0) is; x²/169 + y²/25 = 1
Equation of an ellipseThe equation of an ellipse whose center is the origin, (0,0) usually takes the form;
x²/a² + y²/b² = 1The coordinates of the vertex on the major axis is given as; (13,0) and the focus at (12,0)
Hence, the square of the length of the minor axis;
b² = a² - c²b² = 169 - 144b² = 25.Hence, the equation of the described ellipse is;
x²/169 + y²/25 = 1Read more on equation of an ellipse;

For what value of a does 9=(1/27)^a+3
Answers
[Note: Please review rules of PEMDAS.
The question posted as is means
9=[(1/27)^a]+3 which is probably not what you mean. It has been interpreted with (a+3) as the exponent, please check.]
Need to find value of a that satisfies above.
We will first isolate a in order to solve for its value.
9=(1/27)^(a+3)
Switch unknown to the left
(1/27)^(a+3) = 9
Since both 27 and 9 are powers of 3, we can take log to base 3.
take log (base 3) on both sides, applying rule of logarithm of exponents.
(a+3)log_3(1/27)=log_3(9)
(a+3)log_3(3^(-3))=log_3(3^2)
Apply definition of logarithm [log_a(a^k)=k]
(a+3)(-3)=2
(a+3)=-2/3
a=-3 2/3=-11/3
Check: (1/27)^(-11/3+3)=(1/27)^(-2/3)=(3^(-3))^(-2/3)=3^(-3(-2/3))=3^2=9 ok
Answer: a=-11/3 or a=-3.667 (approx.)
The value of a in the equation [tex]9=(\frac{1}{27})^{a+3}[/tex] is a = -11/3
Solving indical equationsThe given equation is:
[tex]9=(\frac{1}{27})^{a+3}[/tex]
This can be rewritten as:
[tex]9=27^{-1(a+3)}[/tex]
Which can be further simplified as:
[tex]3^2=3^{-3(a+3)}[/tex]
Since the bases are equal, they cancel out
The equation becomes:
2 = -3(a + 3)
2 = -3a - 9
2+9 = -3a
-3a = 11
a = -11/3

A 34 - m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 36 m . Find the length of the shadow. If necessary, round your answer to the nearest tenth.
Answers
34^2 + b^2 = 36^2
1156 + b^2 = 1296
b^2 = 1296 - 1156
b2 = 140
b = sqrt 140
b = 11.8 m <==
Answer:
Length of the shadow is 11.8 meters.
Step-by-step explanation:
In the figure attached,
AB is a 34 meter tall building casting a shadow BC.
Let the measure of BC = x meters
It is given that the distance between A and C is 36 meters.
To find the length of BC we will apply Pythagoras theorem in the triangle.
AB² + BC² = AC²
(34)² + x² = (36)²
1156 + x² = 1296
x² = 1296 - 1156
x² = 140
x = √140
x = 11.832 meters
≈ 11.8 meters
Therefore, length of the shadow will be 11.8 meters.

now, how many days? simply multiply t * 365.
It would take approximately 39 years and 183 days for the deposit to grow to $1 million.
Use the concept of compound interest defined as:
The interest that is computed using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.
Given that,
Initial deposit: $1300
Target amount: $1 million
Interest rate: 17%
Compounding: Continuous
Time to calculate: To the nearest day
To find the amount of time it would take,
Use the formula:
[tex]t = \dfrac{ln(\frac{M}{P})}{r}[/tex]
Where,
t = time in years
M = final amount ($1 million)
P = initial deposit ($1300)
r = interest rate (17% or 0.17)
Find the natural logarithm of the ratio M/P:
ln(1,000,000 / 1,300) ≈ 6.64
Divide the result by the interest rate:
t = 6.64 / 0.17
t ≈ 39.05 years
So, it would take approximately 39 years to grow the deposit to $1 million.
To determine the number of days,
Multiply the decimal part of the years by 365 (assuming a non-leap year):
0.05 x 365 ≈ 183 days
Hence,
Rounding to the nearest day, it would take approximately 39 years and 183 days for the deposit to grow to $1 million.

vito just put some money into a cd that pays 12.7 interest compound quarterly. according to the rule of 72,in the approximately how years will he have 4 times the amount of money that he has now
Answers
Answer:
11.34 years.
Step-by-step explanation:
We have been Vito put some money into a cd that pays 12.7 interest compound quarterly.
Since the rule of 72 states that to find the number of years it will take an amount to double, we need to divide 72 by annual interest rate.
First of all let us find the number of years it will take to double Vito's money by dividing 72 by 12.7.
[tex]\text{Time it will take to double Vito's money}=\frac{72}{12.7}[/tex]
[tex]\text{Time it will take to double Vito's money}=5.66929133858\approx 5.669[/tex]
Since it will take 5.669 years to double Vito's money, so to find the time it will take Vito to have 4 times the money, we will multiply 5.669 by 2.
[tex]\text{Time it will take to have 4 times Vito's money}=5.669*2[/tex]
[tex]\text{Time it will take to have 4 times Vito's money}=11.338\approx 11.34[/tex]
Therefore, approximately in 11.34 years Vito will have 4 times the amount of money that he has now.
