What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!

Sedbober [7]

For f(-2), x will equal -2.

Plug the x-value into the equation:

$2 \times 2^{-2}$

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

$2^{-2} = \frac{1}{2^{2}} = \frac{1}{4}$

Solve the problem:

$2 \times \frac{1}{4} = \frac{1}{2}$

f(-2) will equal 1/2.

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 58-by-58 squar

Savatey [412]

Answer:

We need to find the area of the semicircles + the area of the square.

The area of a square is equal to the square of the lenght of one side.

As = L^2 = 58m^2 = 3,364 m^2

Now, each of the semicircles has a diameter of 58m, and we have that the area of a circle is equal to:

Ac = pi*(d/2)^2 = 3.14*(58m/2)^2 = 3.14(27m)^2 = 2,289.06m^2

And the area of a semicircle is half of that, so the area of each semicircle is:

a = (2,289.06m^2)/2 = 1,144.53m^2

And we have 4 of those, so the total area of the semicircles is:

4*a = 4* 1,144.53m^2 = 4578.12m^2

Now, we need to add the area of the square 3,364 m^2 + 4578.12m^2 = 7942.12m^2

This is nothing like the provided anwer of Val, so the numbers of val may be wrong.

What does x and y equal?

Olegator [25]

Answer:

32 + x= 90

x= 90- 32 = 58

x + y = 90

38 + y= 90

y= 90-38

y = 52
