Elena-2011 [213]
<h3>Answer: D) 0</h3>

Work Shown:

f(x) = 4x^(-2) + (1/4)x^2 + 4

f ' (x) = 4*(-2)x^(-3) + (1/4)*2x .... power rule

f ' (x) = -8x^(-3) + (1/2)x

f ' (2) = -8(2)^(-3) + (1/2)*(2)

f ' (2) = 0

Solve for c<br><br><br> R=5(c/a-0.3)
aalyn [17]

we have

R=5(c/a-0.3)

Solve for c--------> that means that clear variable c

so

Divide by 5 both sides

R/5=(c/a-0.3)

Adds 0.3 both sides

(R/5)+0.3=(c/a)

Multiply by a both sides

a[(R/5)+0.3]=c

so

c=a[(R/5)+0.3]

therefore

<u>the answer is</u>

c=a[(R/5)+0.3]

The lengths of the sides of a rectangle are 12.4 and 26. What are the measures of the angles between its diagonals? Round your a
Sergeu [11.5K]

Answer:

129 and 51 degrees.

Step-by-step explanation:

Drawing a diagonal gives us a triangle  with the opposite side = 12.4 and the adjacent side = 26.

tan x = 12.4 / 26

x = 25.497 degrees.

The other angle will be 90 - 25.497

= 64.503 degrees.

One of the diagonal angles is  180 - (2*25.497)

= 129 degrees

and the other  is 180 - 129 = 51 degrees.
