The area of the base of a triangular pyramid with faces that are equilateral triangles is 64 ft squared. Can you find the surfac

e area of the​ pyramid? Explain. Here are the choices
A. No, because the area of the base of a pyramid is not related to the area of its​ faces, so the surface area cannot be found without more information.

b. No, because the base of a pyramid with equilateral triangle faces does not necessarily have the same area as its equilateral faces.

C.Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.

D.Yes, because the area of the base will be the edge length of each​ face, which can be used to find the area of each face

scoray [572]

Answer:

After population (A) = 62,902 (Approx)

Step-by-step explanation:

Given:

Current population (P) = 19613

Number of years (n) = 2020 - 2000 = 20 year

Rate of growth (r) = 6% = 0.06

Find:

After population (A)

Computation:

After\ population (A) = Current\ population (P)[1+r]^n \\\\After\ population (A) = 19613[1+0.06]^{20} \\\\After\ population (A) = 19613[1.06]^{20} \\\\After\ population (A) = 62,901.548

Find the absolute maximum and absolute minimum values, if any, of the function. (If an answer does not exist, enter DNE.)f(x) =
lyudmila [28]

Answer:

The absolute minimum value is "-\frac{21}{4}" and the absolute maximum value is "15".

Step-by-step explanation:

Given:

f(x)=x^2-x-5

on,

[0,5]

By differentiating it, we get

⇒ f'(x)=2x-1

Set f'(x)=0

then,

⇒ 2x-1=0

          2x=1

            x=\frac{1}{2} (Critical point)

When x=0,

⇒ f(x)=-5

When x=\frac{1}{2},

⇒ f(x)=-\frac{21}{4} (Absolute minimum)

When x=5

⇒ f(x)=15 (Absolute maximum)
