In a report it is said that the predicted minimum temperature is -24 ° C and the maximum is -20 ° C. If the minimum temperature represents colder than the maximum temperature, should it not appear on the reverse? Explain your answer.
Solution
No, it shouldn't appear on the reverse. This is because, just as negative numbers work, they decrease, the further we move away from 0.
Celsius temperature scales are calibrated with respect to the freezing point of water. The freezing point of water serves as the reference point and is called the 0°C.
Temperatures higher than the freezing point of water taken on positive values and temperatures lower, take on negative values. The lower the temperature, the bigger the absolute value of the negative value is.
For example, just like In the question provided, -24°C represents a temperature that is 24° lower than the freezing point of water while -20°C represents a temperature that is 20° lower than the freezing point of water. It is evident that -24°C really is a lower temperature than -20°C.

Answer:
The volume of the resulting cylinder is 385 cm³
Step-by-step explanation:
The formula of the rule of a cylinder is V = π r² h, where
- r is the radius of its base
<em>When a rectangular paper folded to form a cylinder, then one of its dimension will be the circumference of the base and the other dimension will be the height of the resulted cylinder</em>
∵ ABCD is a rectangle
∵ It is folded where AB coincides with DC
∴ AB is the height of the resulted cylinder
∴ BC is the circumference of the base of the resulted cylinder
∵ AB = 10 cm
∴ h = 10 cm
∵ BC = 22 cm
∴ The circumfrence of the base = 22 cm
∵ The circumference of a circle = 2 π r
→ Equate the rule by 22 to find r
∴ 2 π r = 22
∵ π = 
∴ 2 × × r = 22
∴ 
r = 22
→ Divide both sides by
∴ r = 3.5 cm
→ Use the formula of the volume above to find the volume of the cylinder
∵ V = × (3.5)² × (10)
∴ V = 385 cm³
∴ The volume of the resulted cylinder is 385 cm³
Answer:
c = 3
Step-by-step explanation:
Function g is defined as,
g(x) = f(x) - c
Which states that the image function 'g' is formed by shifting function 'f' by c units down along y-axis.
Since, function 'f' has been shifted 3 units down to form the image function 'g'.
Therefore, value of c = 3 will be the answer.
Answer:
The answer would be -439
Step-by-step explanation:
To find this, start by finding t(-7)
t(x) = 3x
t(-7) = 3(-7)
t(-7) = -21
Now that we have this answer, we input it into the s(x) equation.
s(x) = 2 - x^2
s(-21) = 2 - (-21)^2
s(-21) = 2 - 441
s(-21) = -439
