Answer:
The 4-pack light bulbs
Step-by-step explanation:
Price of a light bulb in 3-pack
= 3.45÷3
= $1.15
Price of a light bulb in 4-pack
= 4.20÷4
= $1.05
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)

Distances in space are measured in light-years. The distance from Earth to a star is 4.1 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)? (5 points)
0.23 light-year
2.36 light-years
4.33 light-years
5.36 light-years
Answer:
5.36 light years
Step-by-step explanation:
if a light-year = 9.46 x 1012
9.46 x 1012 = 9512.8
4.1 x 1013 = 4153.3
After that you would subtract
9512.8 - 4152.3 = 5.360.5
the real answer is 5.36 light years
So the distance in light years from earth is 5.36 light years

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?
Answer:
the aswer is 32
Step-by-step explanation:
The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.
To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.
Let's begin by dividing the entire equation by 3 to simplify it:
y = (2/3)x^2 - (16/3)x + 6
Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:
y = (2/3)(x^2 - (8/3)x) + 6
Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:
(8/3) / 2 = 4/3
(4/3)^2 = 16/9
Now, we add and subtract 16/9 inside the parentheses:
y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6
Now, we group the first three terms and factor the perfect square trinomial:
y = (2/3)((x - 4/3)^2 - 16/9) + 6
Next, distribute the (2/3):
y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6
Now, simplify:
y = (2/3)(x - 4/3)^2 - (32/27) + 6
Finally, bring everything together:
y = (2/3)(x - 4/3)^2 + (142/27)
Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).
To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):
m + n = 4/3 + 142/27
To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:
4/3 = (4/3) * (9/9) = 36/27
Now we can add the fractions:
m + n = 36/27 + 142/27
m + n = (36 + 142)/27
m + n = 178/27

Determine the intercepts of the line.
Answer:
x: (5/2,0)
y: (0,5)
Step-by-step explanation:
To solve for x-intercept, substitute 0 for y.
-4x+7=2(0)-3
-4x+7=-3
-4x=-10
x=10/4 or 5/2
To solve for y-intercept, substitute 0 for x.
-4(0)+7=2y-3
7=2y-3
10=2y
y=5

What is the diagonal space of a cube? Can someone detail it to me with an example? Thanks
Answer:
four
Step-by-step explanation:
Space diagonals contrast with face diagonals, which connect vertices on the same face (but not on the same edge) as each other. For example, a pyramid has no space diagonals, while a cube (shown at right) or more generally a parallelepiped has four space diagonals.
