Answer:

  288 km²

Step-by-step explanation:

The surface area is the sum of the area of the square base and the area of the four triangular faces.

  SA = (10 km)² + 4(1/2)(10 km)(9.4 km) = 288 km²

____

The area formulas for a square and a triangle are ...

  A = s² . . . . area of a square of edge length s

  A = 1/2bh . . . . area of a triangle with base b and height h

Let f be the function given by f(x)=5cos2(x2)+ln(x+1)−3. The derivative of f is given by f′(x)=−5cos(x2)sin(x2)+1x+1. What value
lesya [120]

Answer:

The value of c that satisfies the conclusion of the Mean Value Theorem applied to f on the interval [1,4] is approximately 0.1793.

Step-by-step explanation:

Given f(x) = 5cos²x² + ln(x + 1) - 3

The Mean Value Theorem applied to f on an interval [a, b] is given as

f'(x) = c = [f(b) - f(a)]/(b - a)

= [f(4) - f(1)]/(4 - 1)

c = [f(4) - f(1)]/3

f(4) = 5(cos4²)² + ln(5) - 3

= 3.2296

f(1) = 5(cos1²)² + ln(2) - 3

= 2.6916.

c = (3.2296 - 2.6916)/3

= 0.538/3

≈ 0.1793

jek_recluse [69]

Answer:

1/5 or A

Step-by-step explanation:

Hello. Please excuse the idiot above we do not know how he formed or why he speaks like a gorilla on crack. Anyways, we, humans, believe that 1/5 is the correct answer since their are 5 intervals between 0 and 1 between one of the tick marks is 1/5 since there are 5 intervals. I really hope you guys are human not this gorilla above us. I hope I made your day please rate 5 stars , add thanks and please mark brainliest. :)
