E^4x– 6 e ^2x – 55=0

Answer:

Hi there!

The answer to this question is: 1.198945

Step-by-step explanation:

Treat eˣ like a "x" if you can temporarily replace eˣ with "x"

so now it's (x²- 11) (x²+6)=0 then replace "x" with eˣ

then you should get e²ˣ = 11 and e²ˣ = -6

next in order to solve for x, you must ln both sides

and you get 2x = ln(11) and you should get 1.198945

****keep in mind: e²ˣ = -6 will be undefined when you ln both sides

How can you use formulas you already know to find the area and perimeter of a composite figure? The six lane track shown in the
evablogger [386]

The area of the composite figure = 10,874.1 sq. m.

The perimeter of the composite figure = 406.9 m

<h3>What is the Area and Perimeter of a Rectangle and Circle?</h3>

Perimeter of a rectangle = 2(length + width)

Area of a rectangle = length × width

Perimeter of a circle = 2πr

Area of a circle = πr²

<h3>What is Area of the composite figure?</h3>

The figure is made up of two semicircles (1 full circle) and a rectangle.

Area of the composite figure = area of circle + area of rectangle

= πr² + length × width

r = 36.5 + 1.2 = 37.7 m

length = 85.0 m

width = 2(36.5) + 2(1.2) = 75.4 m

Substitute

Area of the composite figure = π(37.7)² + 85.0 × 75.4 = 10,874.1 sq. m.

<h3>What is Perimeter of the Composite Figure?</h3>

Perimeter of the composite figure = perimeter of circle + 2(length of the rectangle)

= 2πr + 2(L)

Plug in the values

= 2π(37.7) + 2(85.0)

Perimeter of the composite figure = 406.9 m

You have 7/8 of sour cream to make tacos if each tacos requires 1/16 cup of sour cream how many tacos can you make
vampirchik [111]
We need to find how many times 1/16 goes into 7/8. So, divide 7/8 by 1/16:
(7/8) / (1/16)
= (7/8) x (16/1)
= (7/8) x 16
= 7 x 16 / 8
= 7 x 2
= 14
The answer is 14.

(Intuitively, since 1/16 goes into 1/8 two times, it goes into 7/8 fourteen times.)
