Tyler just lit a new candle and then let it burn all the way down to nothing. The initial
length of the candle was 15 inches and the candle burned at a rate of 1.25 inches per
hour. Write an equation for L, in terms of t, representing the length of the candle
remaining unburned, in inches, t hours after the candle was lit.
Answer: L=
Answers
1.25 in/hr is an equation for L, in terms of t, representing the length of the candle remaining unburned, in inches, t hours after the candle was lit.
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.L(t) is a function of time, t: L(t) = 15 in - (1.25 in/hr)t
Note that when the candle has burned down to nothing, L(t) = 0. How long does that take? Set 15 in - (1.25 in/hr)t equal to zero and solve for t:
(1.25 in/hr)t = 15 in, or
15 in
t = ---------------- = 12 hrs
L = 1.25 in/hr

Step-by-step explanation:
In the first equation, there is a negative slope (-[tex]\frac{1}{2}[/tex]) so the line should be going downwards and pass by the y-intercept which is 3.
In the second equation, there is a positive slope ([tex]\frac{1}{2}[/tex]) so the line should be going upwards and pass by the y-intercept which is (-1).

Find the sum of first 15 terms of an AP whose 4th and 9th t terms are -15 and -30 respectively.
Answers
Answer:
Sum of the first 15 terms = -405
Step-by-step explanation:
a + 3d = -15 (1)
a + 8d = -30 (2)
Where,
a = first term
d = common difference
n = number of terms
Subtract (1) from (1)
8d - 3d = -30 - (-15)
5d = -30 + 15
5d = -15
d = -15/5
= -3
d = -3
Substitute d = -3 into (1)
a + 3d = -15
a + 3(-3) = -15
a - 9 = -15
a = -15 + 9
a = -6
Sum of the first 15 terms
S = n/2[2a + (n − 1) × d]
= 15/2 {2×-6 + (15-1)-3}
= 7.5{-12 + (14)-3}
= 7.5{ -12 - 42}
= 7.5{-54}
= -405
Sum of the first 15 terms = -405

Step-by-step explanation:
The domain of the function does not include the values x = -3 and x = 3 is the only correct option.
What is a function ?"Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences."
This relationship is commonly symbolized as y = f(x)—which is said “f of x”—and y and x are related such that for every x, there is a unique value of y. That is, f(x) can not have more than one value for the same x. To use the language of set theory, a function relates an element x to an element f(x) in another set. The set of values of x is called the domain of the function, and the set of values of f(x) generated by the values in the domain is called the range of the function."
In the graph plotted,
The graph has no y intercept.
Vertical asymptotes is x = 0
No horizontal asymptotes
Slant asymptotes is y = 2x + 3
Hence, F is the True and A, B, C, D, E are false.

Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds a 150% markup to the total price she paid for the shirt (including the cost of shipping). What is the selling price of each T-shirt?
A. $4.27 per shirt
B. $4.41 per shirt
C. $4.20 per shirt
D. $4.11 per shirt
Answers
Answer: B, $4.41 per shirt
Step-by-step explanation:
To figure this out you want to first take the 200 shirts and multiply them by the cost of $2.80. This gives you a total of $560, without tax. The tax is 5%, so you want to take 560 and multiply it by .05 to find the amount of tax. This leaves you with $28 of taxes. Add that onto the already cost of $560, and it gives you a grand total of $588. She wants to sell the shirts with a 150% markup, so all you do is first find what Michelle really paid for each shirt with tax. Take the total cost of 588 and divide it by the number of total shirts which is 200. 588/200=$2.94 per shirt that Michelle paid. Times that by 1.5% and you get $4.41 per shirt that Michelle is selling.

a cell phone company charges an initial price of $500 for a new phone and then $60 each month after the purchase. if c (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function? r: (0, 500) r: (60, 560) r: ℝ r: (–[infinity], [infinity])
Answers
The range of C(t), the function of the average monthly cost of owning the cell phone, is (60, 560].
The range of a function is the set of all y-values obtained after substituting all possible x-values.
Steps to find the range of a function:
Find the possible domain of the function.For example, Given f(x) = √ (4–x²) ,then, the function is only defined for x² ≦ 4 or –2 ≦ x ≦ 2, or [–2, 2].
Sometimes, the domain is given.Evaluate some values of x into the function to give insight the function's behaviors.Find the minimum and maximum values of f(x).Sketch its graphic, if necessary.
For the given problem:
The price of the device = $500
Monthly plan = $60
C(t) is defined as the average monthly cost of owning the phone.
Let t = number of months of owning the cell phone.
Then, total cost after t month = 500 + 60 t.
Hence, the average is:
C(t) = (500 + 60t)/t
C(t) = 500/t + 60
For t = 1, C(1) = 500 + 60 = 560
For t > 1, C(t) < 560
Therefore the maximum value of C(t) = 560
For t →∞ then 500/t will approach zero, hence:
C(t) →(0 + 60), or C(t) will approach 60.
Therefore, we can conclude that 60 < C(t) ≦ 560, or the range of C(t) is (60, 560].

Rebecca is baking three cakes for a big party. If the recipe for one cake calls for 123 cups of flour, how many cups of flour does she need for three cakes?
Answers
The total number of cups of flour that Rebecca will need to bake three cakes is 369 cups of flour.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the recipe for one cake calls for 123 cups of flour. Also, Rebecca needs to bake three cakes, therefore, the total number of cups of flour that Rebecca will need is,
Total number of cups of flour = Number of cakes × Number of cups of flour in a cake
= 3 cakes × 123 cups of flour per cake
= 369 cups of flour
Hence, the total number of cups of flour that Rebecca will need to bake three cakes is 369 cups of flour.

4. Tell if the measures 6, 14, and 13 can be side lengths of a triangle. If so, classify the triangle as acute,
right, or obtuse.
a. Yes; acute triangle
c. Yes; right triangle
b. Yes; obtuse triangle
Answers
Answer:
A. Yes; acute triangle
Step-by-step explanation:
a=6
b=14
c=13
Using Pythagorean theorem-
c^2 = a^2 + b^2
13^2 = 6^2 + 14^2
169 = 36 + 196
169 = 232
169 < 232
Therefore, (a) the triangle is acute.
If 169 =169 there would be a right triangle.
If c were greater than a + b there would be an obtuse triangle.

Because the bottom of the figure is a line which equals 180°, so you would subtract 80 from 180 to get the angle on the other side of the line dividing the triangles.
Then, you would use the triangle sum theory which states that the angles of a triangle equals to 180.
100 + 25 + x = 180
125 + x = 180
x = 55°
So angle CBD = 55°
