Answer:
∴surface area = 384 unit^2
Step-by-step explanation:
volume =512 unit^3
formula for cube volume is a^3 where a is the length and we know all the length in cube is similar
a^3 = 512
a=8
∴a = 8
∴surface area of cube formula : 6a^2
6 * ( 8 )^2
384 unit^2
hope this helps and appreciate if u mark this as brainliest answer
The Domain of f(x) is real number and the range is y ∈ [-∞, 4].
<h3>What is Modulus function?</h3>
A modulus function is a function which gives the absolute value of a number or variable. It produces the magnitude of the number of variables. It is also termed as an absolute value function.
Here, f(x) = - |x| + 4
Domain of f(x) = Real Number
Range of f(x) ; f(x) ≤ 4
y ∈ [-∞, 4]
Key features:
1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but reflected in the x-axis.
2. The +4 moves the function vertically 4 units upwards.

The distance travelled by an object at time t is given by: d = stwhere d is the distance, s is the speed and t is the time.
Given that the cheetah travels a maximum of 70mph, the distance travelled by the cheetah travelling at 70mph at time t is given by d = 70t
There are 60 mins in one hour, so the distance given in miles per minutes is d = 70/60t = 1.167 miles per minutes.
Part B:
Given that t = 10 minutes, the distance covered by the cheetah in 10 minutes is d = 1.167 x 10 = 11.67 miles.
Part C:
If the cheetah sprinted at maximum speed for 8 minutes and then slowed to 40 mph for the next 8 minutes, then the number of minutes the cheetah have traveled in the first 8 minutes is given by
d = 1.167 x 8 = 9.33 miles.
Part D:
If the cheetah sprinted at maximum speed for 8 minutes and then slowed to 40 mph for the next 8 minutes, then the number of minutes the cheetah have traveled in the second 8 minutes is given by
d = 40/60 x 8 = 5.33 miles
Part E:
The distance the cheetah traveled in the first 8 minutes more than in the second 8 minutes is given by
9.33 miles - 5.33 miles = 4 miles.
Part F:
The ratio of the distance travelled in the first 8 minutes to the distance travelled in the next minutes is given by
9.33 : 5.33 = 1.75 : 1.
Therefore, the distance traveled by the cheetah during the first 8 minutes is 1.75 times greater than the distance traveled during the second 8 minutes.
