Although a linear equation frequently includes a proportional component in addition to some constant number, a linear relationship can also be proportional.
A relationship is proportionate if its graph is a line or ray that passes through the origin. It is not proportionate if the line or ray does not go through the origin. Additionally, something is not proportionate if it is not linear.
As shown in the graph, the straight line passed through the origin which means that it is a proportional relationship.
The constant of proportionality in this case is therefore:
= Calories at a minute / Minute
= 20 / 2 minutes
= 10 calories per minute

The first seven terms of the Fibonacci sequence are: 0, 1, 1, 2, 3, 5, 8, 105, 225.
What is sequence?Sequence is an ordered arrangement of elements, usually numbers or objects, which follows a specific pattern. It is a mathematical concept that is used in a variety of areas, such as computer science, data analysis, and number theory. A sequence can be finite, like the first 10 numbers in the counting sequence, or it can be infinite, such as the set of natural numbers. It is important to understand the concept of a sequence in order to be able to use it in various areas.
The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding numbers, starting from 0 and 1.
The Fibonacci sequence is named after mathematician Leonardo Fibonacci, who introduced the sequence in his book Liber Abaci in 1202.
The sequence is also known as the Golden ratio, because the ratio of successive numbers in the sequence converges on the Golden ratio of 1.618. The first seven terms of the Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, and the fourth and sixth terms of the sequence are 105 and 225 respectively.

Find four numbers forming a geometric sequence such that the second term is 35 less than the first term and the third term is 560 more than the fourth term. Show your work.
Four numbers forming a geometric sequence such that the second term is 35 less than the first term and the third term is 560 more than the fourth term are -35/3, -140/3, - 560/3, -2240/3 and 7, -28, 112, - 448
Four numbers forming a geometric sequence can be calculate as follows
these terms: a₁, a₂, a₃, a₄
a₁ = a₂ + 35
a₃ = a₄ + 560
Use the formula for the n-term:
a₂ = a₁r
a₃ = a₁r²
a₄ = a₁r³
replace
a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35
a₁r² = a₁r³ + 560 ⇒ a₁(1 - r)r² = 560
Subtracting from the first equation to the second:
r² = 560/35
r² = 16
r = √16
r = ± 4
Use the first equation to find the first term:
a₁( 1 ± 4) = 35
1. a₁ = 35/-3 = -35/3
2. a₁ = 35/5 = 7

Now consider just a small mass element of the string. What is the vertical velocity of the string at the origin at time, t
The vertical velocity of the string at the origin at time t would be zero, as the origin is a fixed point.
The origin is a fixed point, so it does not move. This means that the vertical velocity of the string at the origin at time t would be zero.
The origin of the string is a fixed point, meaning that it does not move. This implies that the vertical velocity of the string at the origin at time t would be zero, as the origin does not move or change its position. Since the origin is a fixed point, the vertical velocity of the string at the origin at time t would remain constant, and would be equal to zero.

What does it mean aspect ratio 1 to 3?
Aspect ratio refers to the proportion of the width to the height of a rectangular image or screen. It is commonly represented as two numbers separated by a colon, such as 4:3 or 16:9.
An aspect ratio of 1:3 means that the width of the image or screen is one-third of its height. This aspect ratio is not commonly used for standard images or screen sizes but it can be used for special cases such as vertical videos.
In general, for images and videos, the aspect ratio of 4:3 was used in the past, but now the aspect ratio of 16:9 is more common, and it's the standard aspect ratio used in most modern televisions, computer monitors, and digital cameras.
Also, it's worth noting that the aspect ratio of 1:3 represents a very elongated shape, and it's not suitable for most practical uses, as it would not be able to display most standard content without black bars on the top and bottom of the screen.

Diana will enclose her rectangular tomato garden with 42 feet of fencing material. She wants the length of her garden to be two times the width. What length will meet Diana’s conditions?
a. 28 feet
b. 21 feet
c. 14 feet
d. 7 feet
In order to have length twice width the answer should be 28 feet.
How can you explain it ?Let x be the width of the garden.
The length of the garden is 2x.
The perimeter of a rectangle is equal to 2(length + width)
So 42 = 2(2x + x)
42 = 2(3x)
x = 14
The width of the garden is 14 feet and the length is 2x = 2(14) = 28 feet.
The answer is 28 feet (Option a).

Sheila either walks or cycles to school
the probability she walks to school is 0.65
if she walks to school, the probability she is late is 0.4
If she cycles, the probability she is late is 0.1
Work out the probability that on any one day Sheila is late
The probability that Sheila is late on any one day is 0.295 or 29.5%.
We can use the law of total probability to find the probability that Sheila is late on any one day.
The law of total probability states that for any event B, the probability of event B occurring can be calculated by summing the probability of event B occurring given that event A has occurred, multiplied by the probability of event A occurring. Symbolically, this can be represented as:
P(B) = P(B|A1) * P(A1) + P(B|A2) * P(A2) + ... + P(B|An) * P(An)
In this case, event B is Sheila being late, and events A1 and A2 are Sheila walking or cycling to school, respectively. The probabilities of these events occurring are:
P(A1) = 0.65 (the probability that Sheila walks to school)
P(A2) = 0.35 (the probability that Sheila cycles to school, since 1- 0.65)
P(B|A1) = 0.4 (the probability that Sheila is late given that she walks to school)
P(B|A2) = 0.1 (the probability that Sheila is late given that she cycles to school)
Plugging these values into the equation gives:
P(B) = P(B|A1) * P(A1) + P(B|A2) * P(A2) = 0.4 * 0.65 + 0.1 * 0.35 = 0.26 + 0.035 = 0.295
So the probability that Sheila is late on any one day is 0.295 or 29.5%.
