Answer:

To solve this problem you can divide the figure is known figures that have exact formulas for calculate their areas. As you can see in the figure attached, you can divide in two trapezoids, one rectangle and two right triangles. Therefore, you have:

Area=((4+3)6)/2+((6+3)5)/2+(3x1)+(3x4)/2+(3x3)/2

Area=21+22.5+3+6+4.5

Area=57

The answer is: The area is 57

Verify this identity: secx-cosx = 1-cos^2x/cosx

Sauron [17]

Step-by-step explanation:

sec x − cos x

Secant is the inverse of cosine:

(1 / cos x) − cos x

Find the common denominator:

(1 / cos x) − (cos² x / cos x)

Subtract:

(1 − cos² x) / cos x

Answer:

Compound Interest= $3440

Final Amount= $5440

Step-by-step explanation:

Compound Interest's formula= P(1+r/100)^n

where P is Principal, r is Rate then n is Years

So in this case,,2000(1+.72)^1 = $3440

Hence, Total Amount = Principal+Interest

therefore T.A= $2000+$3440

T.A=$5440

Answer:

The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56.

2^x-4x=0 find the value of x in the equation

ella [17]

9514 1404 393

Answer:

x ≈ 0.309906932381 or 4

Step-by-step explanation:

There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.

Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.
