Find the first derivative of y = sin^2(cos2x)

AveGali [126]

Hello,

y=sin²(cos(2x))
y'=2*sin(cos(2x))*cos(cos(2x))*(-sin(2x)*2)
= -4*sin(cos(2x))*cos(cos(2x))*sin(2x)

A triangle has sides represented by 7, x, and x−1. If the perimeter is 28, find the length of the longest side.

aleksley [76]

Answer:

x (11 unit) is the longest side

Step-by-step explanation:

Given:

Sides;

7, x, and x−1

Perimeter = 28

Find:

Longest side

Computation:

Perimeter = sum of all sides

So,

7 + x + (x -1) = 28

2x + 6 = 28

x = 11

So,

x -1 = 11 - 1 = 10 unit

x (11 unit) is the longest side

Answer:

Δ HGI ≅ ΔEDF

Step-by-step explanation:

Given:

Δ DEF ≅ Δ GHI

From the given congruence statement we can figure out the corresponding sides that are congruent.

The arrangement shows:

$D\rightarrow G\\E\rightarrow H\\F\rightarrow I$

So the rearranged statement can be written as:

ΔEDF ≅ Δ HGI

∴ Δ HGI ≅ ΔEDF
